3

ANSWERS AND DEPOSITION OF G. BRENT DALRYMPLE, Ph.D.,

a witness produced on behalf of the Defendant, taken in the above style and numbered cause on the 3rd of December, 1981, before Laura D. Bushman, a Notary Public in and for Pulaski County, Arkansas, at the office Mr. Robert Cearley, 1014 West 3rd Street, Little Rock, Arkansas at 10:35 a.m., pursuant to the agreement thereinafter set forth.

G. BRENT DALRYMPLE, Ph.D.

the witness hereinbefore named, being first duly cautioned and sworn to tell the truth, the whole truth, and nothing but the truth testified as follows:

DIRECT EXAMINATION

BY MR. WILLIAMS:

Q. Would you please state your full name, please?

A. Gary Brent Dalrymple.

MR. WOLFE: David, perhaps before we begin we ought to speak about the documents.

MR. WILLIAMS: All right, sir.

MR. WOLFE: Dr. Dalrymple has — has made a document production in response to defendants request for documents. The only two points of interest about the production are that Mr. Williams and I have agreed that all the materials which were not reprints of published articles will be given circulation limited to the purposes of this lawsuit, and I've also informed Mr. Williams that plaintiffs
 

4

have withheld certain products under the Work Product Doctrine. They are specifically certain letters and notes, and reprints of a few articles which were sent and exchanged

between Dr. Dalrymple and attorneys for plaintiffs in preparing the case, and a proposed question and answer list relating to Dr. Dalrymple's possible testimony.

MR. WILLIAMS: Is that it?

MR. WOLFE: That's it.

MR. WILLIAMS: For the record, I want to object to the claim of Work Product Privilege. I think that this is not the client of the plaintiff — of these — of these attorneys. Mr. — Dr. Dalrymple is an expert witness who is supposed to be testifying objectively. Therefore to claim a Work Product Privilege on parti — particularly documents that he has written, I think it's inappropriate and not supported by the law. Further, I think it is particularly inappropriate in light of what I think will be shown in this deposition that Dr. Dalrymple is not supposed to be testifying for either side but presenting objective facts in this case. Therefore to claim the Work Product Privilege when he is not to be a witness for either side is — is — is particularly inappropriate.

MR. WOLFE: Well, we certainly agree that — that there is no attorney/client relationship here and the Work Product Doctrine is asserted because the questions
 

5

that were addressed to Dr. Dalrymple and the areas that he was asked to consider we regard as evidencing the workings of the minds of the attorneys on the plaintiffs' side here, and that's the basis for our asserted privilege.

BY MR. WILLIAMS:

Q. Dr. Dalrymple, have you ever had a deposition taken before?

A. No.

Q. Have you ever testified in court before?

A. No.

Q. Has Mr. Wolfe or some other attorney for the plaintiffs explained to you what a deposition is?

A. Yes.

Q. All right. Well, then if I do ask any questions that are unclear, I want you to please tell me so and I will try to make them clear. There will probably be several when I get into some of the — some of the dating methods.

A. Okay.

Q. Also, let me tell you that our purpose here is to simply try to discover what your testimony might be, and as this colloquia we just had over the — over the Work Pro — Product that doesn't concern you personally I don't think, and we are simply trying to make our record in — in doing our job for our clients.

A. I understand.
 

6

Q. I've been supplied with a copy of a document which appears to be your curriculum vitae. I would like to have this marked as exhibit — defendants' exhibit one to the deposition.

[Thereupon State's Exhibit #1 was marked for the record.]

Q. Can you identify that as being your curriculum vitae?

A. Yes.

Q. It includes a list of publications. Is that correct?

A. That's right.

Q. Is that list of publications everything that you have ever had published not limited — I'm not limiting myself now but — now to simply scientific articles?

A. Yes. The only thing I've ever had published has been scientific articles.

Q. Where are your daughters attending school?

A. At Gunn High School in Palo Alto.

Q. Is that a public or private school?

A. That's a public school.

Q. Do you know if they have taken any science courses as of yet?

A. Yes, they have

Q. What courses have they taken?

A. Well, I don't think I can remember a complete list they have taken mathematics, general science courses.
 

7

My two older daughters have taken a course in biology. My oldest daughter is taking a physics. Two oldest ones have had courses in chemistry.

Q. Uh-huh. Do you know whether the creation-science model or theory of origin was ever mentioned in a classroom?

A. As far as I know, it was not.

Q. Has the evolution-science model or theory of origins ever been mentioned in their classroom?

A. In the — they were taught some evolution in the biology course and perhaps another general science course. I really don't know.

Q. Are you aware that back in 1969, I think it was, that the California Board of Education issued a statement on creation-science as being — it — I'm paraphrasing now so I'm — I — `a scientific alternative to evolution'?

A. I am generally aware that at one time they did make such a statement, yes. Then it was later revised.

Q. That was later revised? But — but to your knowledge as a citizen of the state of California do — do you know whether in Palo Alto public schools for example whether creation-science was presented pursuant to that resolution?

A. I have no knowledge one way or the other.

Q. Is your wife employed? I — she's a teacher according to your vitae I —

A. She's a teacher
 

8

Q. Where does she — she teach?

A. She teaches at a private school.

Q. What school is that?

A. It's called Pinewood. Pinewood Private School in Los Altos.

Q. Is that — what does she teach there?

A. She teaches mathematics presently to six grade, I believe.

Q. What is her degree?

A. She has a bachelor's degree.

Q. In what area?

A. Education.

Q. Elementary education or —

A. Yes.

Q. Is that a private school or affiliated with any group or church?

A. No. It's — it's purely a private school. It's nonprofit.

Q. Nonprofit.

A. It's not affiliated with any church.

Q. Do you know whether in that school the creation-science model of origins is discussed?

A. I have not heard that it is.

Q. Is that school to your knowledge — well, how long has that school been in existence?

A. I don't know but for many years.
 

9

Q. Do you know who formed it or the reasons why it was formed?

A. I — I know who — I know who formed it. I do not know the reasons why it was formed.

Q. Who formed it?

A. I'm trying to think of their names and now I've forgotten them. Perhaps it will come to me later, I'm sorry.

Q. Okay. Has it at any time been affiliated with any — any group, any religious sect or any other group?

A. To my knowledge, the school has not.

Q. Why does your wife teach in a public a private school as opposed to a public school?

A. Because at present, positions in public schools are extremely hard to get in California and at one time she did teach in a public school and then she quit to have a family, and when she went back jobs were not easily available particularly in Palo Alto.

Q. Are you a member of any organized religious faith?

A. No.

Q. Have you ever been a member?

A. When I was a teenager I attended church regularly, yes.

Q. What church did you attend at that time?

A. A variety. Methodists, Baptists, Friends, a few services in a Catholic church.

10

Q. Were you ever a member of any of those churches?

A. No.

Q. When did you begin attending churches, your — as I best you recall now?

A. I really can't remember. When I was quite small.

Q. When did you cease to attend church services?

A. When I was in my mid-teens.

Q. What is your personal opinion as to the existence of a god?

A. Well, I — hmm. The reason I am pausing is because I don't normally give that question much thought. I have seen no evidence that requires me personally to believe in a god.

Q. Do you have any statement of your religious faith that you would subscribe to or the lack thereof?

A. I have never tried to put myself in a category if that is what you're — what you're asking.

Q. Well, I am sure you are familiar with the terms which are sometimes used such as deist, agnostic, atheist. Would any term or any such similar term be accurate in describing your own religious faith?

A. I have not studied the definition of those carefully enough that I think I want to commit to one or the other. If you would care to define for me maybe I could —

Q. Well, if a deist means simply that someone who believes
 

11

there is some sort of sub — god but not in the sense of a personality, as a person, as a personality or maybe — maybe agnostic is someone who doubts the existence of a god and an atheistic is one who believes that there is no god. Between those three terms could one more accurately describe your own views?

A. Well, I guess perhaps half way between an agnostic and an atheistic.

Q. Okay.

A. I try to remain open minded on questions like that.

Q. You said you have seen no evidence which would require you to believe that there is a god. Do you — for you to believe that would there have to be some evidence?

A. Yes.

Q. What sort of evidence do you think it would take to convince you?

A. I am a scientist and I tend to deal in scientific evidence but that's a difficult question to answer because, I know people at certain stages of their life sometimes are willing to accept evidence and other times they're not. So I guess the answer to your question is I don't know.

Q. You're not aware of what — of what evidence it would take?

A. No. Because I think that would be a highly personal happening, if and when it ever did happen and I'm not sure
 

12

how that would happen or what it would take.

Q. Okay. Did you at one time when you were attending church in your childhood and your teens, did you at that time have a belief in a god?

A. I think that I was brought up to have a belief in a god. My family had a tradition of such beliefs. Is — does that answer your question?

Q. Well, you were brought up to — no, I don't think that really it does. Because I asked you did you have?

A. I'm not sure how — how fastly I ever held that belief. One of the reasons I went to different church with what — what I was hearing. So I think that I was more inquisitive then held any belief very hardly.

Q. Do you think that a religious person can be a competent scientist?

A. Oh, yes.

Q. Do you think that a person — do you think there is any correlation between the presence and degree of a person's religious faith and their competence as a scientist?

A. I don't think there has to be but it depends on how the individual wants those two disciplines to interact, I think.

Q. Do you have a — heard of a code of personal conduct?

A. Yes.

Q. Could you describe it for me?
 

13

A. Well, I think it pretty much probably parallels to the Ten Commandments. I come from basically a Christian background and I think that the morals and code of ethics that are taught there are — are fairly valuable to — including not lying, cheating, stealing, hurting other people and so forth.

Q. Have you ever been a member of any other sort of group such as the ethic — Ethical Society or Society of Religious Humanists or any group like that?

A. No.

Q. Where are you presently employed?

A. I am employed by the Department of Interior, Geological Survey in Menlo Park, California.

Q. And what position do you hold there?

A. I am the assistant chief geologist for the western region.

Q. Okay. Would you just very briefly describe what the purpose of the U.S. Geological Survey is?

A. Well, it has a multiplicity of purposes. It conducts geological research, it makes topographic maps of the United States and its territories, it manages and collects royalties on mineral and oil resources on federal lands and it's concerned with water quantity and quality throughout the United States.

Q. How long have you been involved — been employed in
 

14

one capacity or another for the U.S. Geological Survey?

A. It's been since about June of 1963. So that would be about what — about eighteen years. Eighteen and a half.

Q. And prior to that time you were with the National Foun — Foundation?

A. No. I was a student at the University of California at Berkeley.

Q. From when to when?

A. Well, that would have been from about September of 1959 until June of 1963.

Q. And you received your Ph.D. in 1963, correct?

A. That's correct.

Q. Did you write a dissertation?

A. Yes. I did.

Q. What was the topic of your dissertation?

A. The topic was described in the title. It's the Cenozoic chronology of the Sierra Nevada.

Q. What is Cenozoic?

A. Well, the Cenozoic is a period of geologic time that goes from the present back to about sixty-five or seventy million years.

Q. How is that spelled?

A. C-E-N-O-Z-O-I-C. Usually with a capital C.

Q. When did you first study radiometric dating?
 

15

A. When I was first a graduate student at Berkeley.

Q. What is Occidental College?

A. That's a liberal arts college in southern California.

Q. Is it affiliated with any private groups?

A. Not — it's a private school if that is what you are asking?

Q. Right. Is it affiliated with any sort of private groups such as religious or specific groups?

A. It has not been affiliated with a religious group for many decades. I do not recall but there originally was, I believe.

Q. As assistant chief geologist, are your duties more administrative than they are research?

A. Yes. I've only held that position for a few months, however.

Q. Since May?

A. The end of May or the first of June, yes.

Q. What area is covered by the western region?

A. It consists of the six western states plus Alaska plus Hawaii and the Pacific trust territories. Would you like me to name the states?

Q. No. That's all right. And prior to that time you were branch representative for the Menlo Park, Branch of Isotope Geology?

A. That's correct
 

16

Q. Were your duties there more in the area of research or administration?

A. Primarily research.

Q. Of your publications, approximately how many have been written in the course of your employment?

A. With the Geological Survey?

Q. Yes.

A. All but about two, I believe.

Q. I also notice that on your list of publications there is either a P or an A or in some cases there is an O. What do those represent?

A. The P's are publications published in the traditional scientific literature. The A's are abstracts for scientific meetings. We normally don't count those as publications. They are brief paragraphs describing a talk. And the O's, if I remember correctly, are internal administrative type reports but the ones listed in there are — are scientific internal administrative reports.

Q. So you have studied radiometric dating for approximately I twenty-one years, is that correct?

A. That's approximately correct.

Q. When did the concept of radiometric dating originate?

A. It started with a paper by Boltwood in the early 1900's shortly after it became known that there was such a thing as radioactivity.
 

17

Q. And could you just briefly sketch for me the history of radiometric dating in terms of it's acceptance within the scientific community as you view it?

A. Well, I think it was accepted as a viable possibility from — from the earliest proposal that such a scheme might work.

Q. Uh-huh.

A. But in the early days not all of the physical principles had been developed. For example, when the first lead ages had been — were calculated by Boltwood it was not known that there were things like isotopes and there was not equipment developed then to measure them. I think it's been accepted as an accurate, reliable technique generally for probably close to thirty years now. It's —

Q. For the rate continually —

A. — continually improves.

Q. All right. But there was a period there of — in the early 1900's until approximately in somewhere of the 1940's 50's when it was — it was not fully accepted, is that correct?

A. That's correct. It was highly experimental. There seemed to be lots of problems and gradually those have been overcome.

Q. Is there one point to which you can direct me or one article or event in which — kind of established radiometric
 

18

dating in your mind as being scientific and eliminated the problems which had been viewed earlier?

A. I don't think so. Because there are a variety of different radiometric techniques and each one has it's own history and most of them have evolved through a series of experiments from things that were highly speculative to an end point which is considered highly reliable. And I don't think there was any single point probably in any of those that would — would have been considered definitive.

Q. Prior to the rise of radiometric dating as a dating technique, what techniques were utilized in the scientific community?

A. To do what?

Q. To date — to date rocks and to date — date the earth?

A. Oh, there were a variety of things that were attempted including rates of sedimentation, cooling of the earth. Geologists used to attempt to estimate the age of the earth based on the general rate at which they saw general processes working and none of those worked very well.

Q. Have all of those now been discarded?

A. Yes.

Q. You are a member, actually a fellow I think of The Geophysical Society of America? Could you briefly describe what The Geophysical Society of America is?

A. You mean the American Geophysical Union?
 

19

Q. No. The Geophysical Society of America. Oh, excuse me. I'm sorry. I think I was reading on two lines. It's Geological Society of America.

A. Geological Society of America. Okay. That's I suppose the principal geological organization of geoscientists in the United States perhaps in North America.

Q. What's the active membership to your knowledge?

A. I really don't know.

Q. And when were you selected a fellow? Were you elected first of all?

A. Well, a fellowship in The Geological Society is not elected.

Q. Okay.

A. It's after five years you can apply and I think pay a small fee and you're made a fellow. That's not true of some of the other societies like the AGU. That's a different situation.

Q. The American Geophysical Union. Do you care to describe what that is?

A. That's basically a geophysical society. That consists of an affiliation of oh about a dozen or so sections, each section with different interests. There is a section on volcanology, geochemistry and petrology. There's a section on hydrology. There are sections on upper atmosphere physics. There is a section on planetology.
 

20

Q. What sections are you a member of?

A. Volcanology, geochemistry and petrology. That's one section.

Q. Okay. And you were selected as a fellow by what method?

A. Fellowship in the American Geophysical Union is — is elective. It's restricted to, oh, I think about three per cent of the membership.

Q. When were you elected?

A. Oh, I don't remember. I think it was about 1975.

Q. And what is the American Quaternary —

A. Quaternary.

Q. —Quaternary Association?

A. That is a group of scientists who are interested in problems of the Quaternary period of geologic history which is just the last few million years.

Q. Have any of these societies taken a formal or informal position on creation-science?

A. Not that I know of.

Q. Did you take any courses in biology in the undergraduate or graduate school?

A. No.

Q. Do you have any expertise in the area of biology?

A. No, I do not. I had one course in paleontology as undergraduate. I don't know if you want to include that in biology or not but I'll mention it.
 

21

Q. Okay.

A. In case you'd like to.

Q. Do you recall, you know, in your undergraduate or graduate school days studying theories of origin of the universe, of life, of man and of the earth?

A. I guess that depends on what you mean by origin. If you mean by that the way things were shaped as we now see them, then the answer is yes. If you mean by that ultimate origins, then the answer is no.

Q. Could you explain how you see the difference between those two?

A. Well, the first one is basically how the things that we observe today got to be that way by natural processes. How they I hate to use the word `evolve' but will you let me use it in a different sense? How they change —

Q. You mean it in a nontechnical sense —

A. — in a nonevolutionary sense. Yes, that's right. Okay. The other one, the question of ultimate origins of the universe and of matter is primarily a philosophical or religious subject in that — that I did not study in any of those courses.

Q. Have you ever taken any courses in religion?

A. Yes. At Occidental College everyone was required to take a one semester course, I believe, in religion and the the course consisted of the Bible as literature.
 

22

Q. The Bible as literature?

A. Yes.

Q. Taking then your first definition of theories of origin, how things got to be the way they are today, what courses or what disciplines did you study which would address that subject?

A. Do you mean in a broad sense like geology or specific courses within geology?

Q. First just take the broad sense.

A. Well, I've had courses in geology, some courses in physics and chemistry. Most of them that would fall in that category would be geology.

Q. How many courses in physics or chemistry did you take?

A. Oh, I really don't know. Totalling perhaps half a dozen. I don't remember.

Q. Did you ever study the creation-science model of origins in school?

A. No.

Q. Now, are the three professional societies which you have listed on your curriculum vitae the only groups of which you are a member? Science and non-science?

A. Do I take it then that you mean formalized groups?

Q. I mean formal groups, you know, where you have joined, you are a member.
 

23

A. I belong to a yacht club.

Q. I assume that they have not taken a position on creation-science?

A. As far as I know, they have not.

Q. What is the Society of Irre — Irre — Irreproducible Research?

A. Oh, that's a sort of lighthearted organization to which one really doesn't belong you simply subscribe to their journal which is series of articles that spoof science.

Q. Uh-huh.

A. It's sort of science's Punch if you — if that's a good analogy.

Q. Have you ever written any articles?

A. No. I have been tempted but I've not yet.

Q. What's the American Nuclear Society?

A. That's — that's a group to which I don't belong but which has — which — is that a committee task that you're — Yes. That's — that's a group that is concerned with factors involving nuclear reactors and nuclear standards, and I was invited to be on a working group to write standards for siting earthquake — for siting of nuclear reactors with specific regard to earthquake hazards. I'm not a member of that society.

Q. You said earlier that there were various methods of radiometric dating, is that correct?
 

24

A. That's correct.

Q. Could you list for me what you consider to be the main areas — the main types of radiometric dating?

A. I think potassium-argon including its variation of argon-40/argon-39.

Q. So those would be kind of sub-areas of potassium-argon?

A. Yes. Those are based on the same decays

Q. That's argon-40, you said?

A. Yes. Argon-40/argon-39. And those two go together usually with a slash between them or something like that.

Q. Okay.

A. The difference is basically in how the measurements are made. Rubidium/strontium would be another one. I'll write that one down. Uranium/lead concordia-discordia method.

Q. Uh-huh.

A. Carbon-14 and there are a few new ones that are now being used because analytical techniques have developed to the stage where it is now possible to make measurements it wasn't possible to do before. And those include neodymium-samarium.

Q. Is that neo?

A. Neodymium, yes. N-E-O-D-Y-M-I-U-M. Samarium. S- A-M-A-R-I-U-M. And lutetium, L-U-T-E-C-I-U-M, I believe. I'm not even sure how that one is spelled.
 

25

MR. WOLFE: T. L-U-T-E-T-I-U-M.

BY THE WITNESS:

A. T-I-U-M. That's right. Hafnium. H-A-F-N-I-U-M.

Q. Is this the third one?

A. No.

Q. Oh, part of lutetium?

A. Yeah.

Q. Hafnium? Okay.

A. Now, those are not — the last two are not in terribly common use because the measurements are difficult but they are becoming the principal methods for certain kinds of studies. I think that those are the major ones which is —

Q. Are you — do you consider yourself, placing humility aside, to be an expert in all these areas?

A. I suppose it depends on what you mean by expert. Most of the measurements that I've been involved in myself are concerned with potassium/argon, some with rubidium/strontium and I've studied the others.

Q. Have you ever used the other?

A. I've never used the others.

Q. Why have you used essentially potassium/argon and rubidium/strontium?

A. Those are the two that have probably the broadest applicability for most geologic problems in which I've been interested. In particular, the potassium/argon method.
 

26

Q. A document has been filed in this case earlier which is entitled, Radiometric Dating, Geologic Time, and The Age of The Earth. A Reply to Your "Scientific" Creationism by G. Brent Dalrymple, and it's dated 8-4-81. Did you write this document?

A. The title page looks familiar, yes.

Q. Would you like to —

MR. WOLFE: There's another copy here.

MR. WILLIAMS: Okay. If he — you might want to get that for him.

BY THE WITNESS:

A. Yes.

Q. When did you write this document?

A. I started writing that about March of 1981. And the draft you have was typed on the date that you see on the bottom.

Q. And what was the occasion that you began to write this document?

A. I wrote this after the Segraves trial in California.

Q. Why did you write it after the trial?

A. As you probably know the complaint in that trial was changed so that most of the scientific witnesses did not appear. And some of us discussing our experiences over dinner one evening —
 

27

MR. WOLFE: Excuse me a second —

[Off The Record Discussion.]

BY MR. WILLIAMS:

Q. You — you want to read back what he said?

[Thereupon the Court Reporter read back the preceding answer]

A. — decided to take advantage of the time we had put into preparing for that trial by writing up what we had learned and possibly putting it in a book

Q. And who over dinner discussed this?

A. There was Bill Mayer, Richard Dickerson of Cal Tech, Tom Jukes of Berkeley. I believe Junji Kumimoto was there from UC Riverside and myself. That's all I can remember

Q. Is this going to be published?

A. Yes

Q. Where is it going to be published?

A. We're not sure who the publisher is going to be. We have a tentative agreement with the publisher at the moment

Q. And what publisher is that?

A. It's William Kaufmann Company of Los Altos

Q. And to what audience have you written this? Do you have a plan on to whom it will be marketed and distributed?

A. It's directed primarily at people who have to deal with scientific creationism in their literature It is intended to be a partial reply to some of the criticisms
 

28

that those people have to some of the conclusions of science.

Q. When did you actually first start writing this?

A. I think I said it was in March.

Q. Has your involvement in this case here in Arkansas, has it affected what you have written here?

A. No. That was completed before I was approached about this.

Q. Have you read Act 590?

A. Yes. I did several months ago.

Q. I am going to refer you to your manuscript. Page 1 the introduction where you state, "scientific creationism as represented by Morris, Kofahl and Segraves and others is a model for the creation and history of the universe based on a literal interpretation of parts of the book of Genesis". Have you made a decision in your own mind if that is what Act 590 requires? The teaching of the literal interpretation of Genesis?

A. Act 590 I think specifies the teaching of scientific creationism and from the body of literature on scientific creationism that I have read that, is the conclusion that that I come to, yes.

Q. Much of the literature on scientific creationism that you have read does include references to religious works, does it not?
 

29

A. Yes.

Q. Are you aware that Act 590 specifically prohibits any religious instruction and also prohibits any references to religious writings?

A. Yes. I am aware of that but I think that would be difficult to do.

Q. So many of the — without asking for a legal judgement are you aware that many of the books and articles on the sci — creation-science of which you have read and on which you may rely may very well violate the Act?

A. Would you repeat that for me?

Q. That many of the articles which you have read may very well violate the Act?

MR. WOLFE: Is that a question and if so I didn't catch it.

BY MR. WILLIAMS

Q. Are you aware of that fact whether they will violate the Act? And I'm not asking for a legal judgment I'm just — just —

MR. WOLFE: No. No. I'm — I'm — object to the form of the question and ask whose view that is that that is a fact and I would like to have that specified within the question.

MR. WILLIAMS: I'm not asking him not if it is a fact but I'm asking him if he is aware
 

30

as to whether many of these publications on scientific creationism which he has read, if he is aware as to whether or not they would violate the Act.

BY THE WITNESS:

A. Well, I — without interpreting the law I don't know how I could answer that.

[Thereupon State's Exhibit #2 was marked for the record.]

Q. Let me show you what has been marked as State's Exhibit #2 and ask you to look at it and tell me if you can identify that — those documents, please?

A. Is this the top sheet or the whole package?

Q. The whole package is State's exhibit. Can you identify that?

A. Yes. That's a reply that I received from Bill Mayer.

Q. Do you have the letter that you sent to him?

A. I could not find it.

Q. Did you — could you tell me as best you recall what your letter to him said?

A. Well, I asked him if he could send me any copies of resolutions opposing the teaching of creationism as science from professional scientific organizations. And in reply he sent me that letter and the copies that are attached to it.

Q. Why did you write him for — for those resolutions?

A. I was interested in the possibility of drafting a similar resolution for the American Geophysical Union and I wanted to find out what other societies had said.

Q. Why did you become interested in drafting a resolution for the American Geophysical Union?

A. Because I thought it was fairly important that religious subjects not be introduced in the science classroom and I thought it was appropriate for the AGU to at least consider this matter as part of their involvement in science education.

Q. When did you first decide that you were going to try to draft a resolution?

A. Well, I don't remember. Spring or summer. What is the date on Bill Mayer's letter? It would not have been too much before that?

Q. March 30 of 1981.

A. Okay. It would have been in March then.

Q. Do you have any authority within the AGU for resolutions on education?

A. I'm the secretary of the section of volcanology, geochemistry and petrology and as such am an officer of one of the sections. And any member is allowed to submit any matter for consideration by the council. Yes.

Q. But are you charged with the responsibility of either drafting resolutions or being responsible for matters in education within that organization?
 

32

A. No more so than any other officer or member of the AGU.

Q. Are any other officers charged with that responsibility, either responsibility?

A. Well, the officers of the AGU are charged with the responsibility to oversee all the functions of the society and one of those includes attitudes toward public education. There is also a committee on — on education — science education.

I don't remember the exact title of that committee. I'm not a member of that committee.

Q. Who is chairman of that committee?

A. His name is Chris Russell.

Q. What specifically motivated you to write Bill Mayer and drafting such a resolution?

A. My motivation was that I think it would be very unhealthy for science and the public at large to teach nonscience topics as science in the public schools.

Q. Was there any one event which prompted you to take this course of action?

A. I — not specifically but I think if there was one event it was probably the Segraves trial.

Q. What involvement did you play in the Segraves — role did you take in the Segraves trial?

A. Well, in the end I played virtually no role but I was asked by the Deputy Attorney General of California to appear as witness. And did go to Sacramento and was prepared to
 

33

appear on essentially the same basis that I am appearing here, but the complaint was changed and I did not in fact appear.

Q. In anticipation of your testimony in that case, did you review books or works on creation-science or scientific creationism?

A. Yes I did. On request from the Deputy Attorney General.

Q. And how did you select which books you reviewed or articles?

A. I started with the ones that he sent to me and some of those books or articles referred to other articles which I then obtained and read in whole or in part.

Q. Was that your first exposure to creation-science?

A. It was not my first exposure, but it was my first involvement.

Q. Do you recall when you were first exposed to creation-science or scientific creation?

A. Yes. It was back in approximately 1975 give or take a year when Duane Gish and Henry Morris of the Creation Research Institute came to Menlo Park to give a talk at the Geological Survey to a group of geologists. There were several hundred present at the evening lecture. And the next morning they requested a tour of the radiometric dating labs which a colleague of mine and I gave them. And I sat down across the table with Morris and Gish and we
 

34

discussed scientific creationism and the second law of thermodynamics for about thirty minutes. They had a tour of the laboratory and that was the complete extent. After — after they left they had left copies of some of their works including a book by Henry Morris called, Scientific Creationism: Public School-Edition, and I believe a paper by Slusher, "Critique of Radiometric Dating" and a paper by Thomas Barnes on The Decay of the Magnetic Field. And I read through those just out of interest after hearing their talk, and then I put the matter aside and didn't even think about it until contacted by the State of California.

Q. What was the subject of the talk that evening?

A. Well I don't remember what the titles were. Each of them gave, a — gave a talk. It was basically what they considered to be the scientific evidence for creationism.

Q. And do you recall now what your response or opinion was of their talks?

A. Well, I thought scientifically they were extremely poor talks.

Q. Is that all that you can recall about your reactions to it?

A. I was somewhat appalled that they were attempting to pass what appeared to be religious beliefs as science.

Q. Do you know if you plan to rely on any statements that were made during that talk or that meeting that you
 

35

had with them in your testimony in this case?

A. Not as far as I know, no.

Q. Do you recall if they talked about Genesis during that talk?

A. I don't really remember specifically what the topics were. That's been a long time ago.

Q. In 1975 you had that brief involvement and exposure to creation-science or scientific creationism at least as practiced or espoused by these two individuals?

A. Yes

Q. And then you say your next involvement was not until the Segraves case in California?

A. A few months before the Segraves case when I was contacted by the Deputy Attorney General and he asked me to read and evaluate some of their literature.

Q. When were you contacted by the California Attorney General's office?

A. I don't remember I think it was about December in the year before but I'm not clear. It was — it was a few months before the trial.

Q. What year was that now? That would be September —

A. Well, that would have been in late — late 1980, very late 1980 or perhaps it could have been January 1981. I just don't recall.

Q. During that five year period, did you make any effort
 

36

to try to read on any basis, regular or irregular, some of the scientific creation-science literature?

A. No.

[Thereupon State's Exhibit #3 was marked for the record.]

Q. Dr. Dalrymple, I want to show to you what has been marked as State's Exhibit #3 and ask you to look at that document and tell me if you can identify it?

A. Yes, I can.

Q. And what is it?

A. Well, that's the series of correspondence between myself and other officers of the AGU discussing a draft of a resolution opposing the teaching of scientific creationism as science.

Q. When were you first contacted about possibly testifying in this case?

A. I don't remember, but I think I have that in a notebook which is here today. If you would like me to look that up I probably could find that out?

Q. I would like you to.

A. This may take a little time.

Q. While your looking through let me inquire of Mr. Wolfe —

MR. WILLIAMS: Is the notebook that he is looking through something you claim is a privilege,
 

37

a Work product?

MR. WOLFE: Off the record.

[Off the Record Discussion.]

BY THE WITNESS:

A. The contact that I have is September 17th.

Q. 1981?

A. 1981.

Q. The second page of the Exhibit #3 to your deposition is styled a, "Resolution Opposing the Teaching of Creationism as Science in the Public Schools Draft 19 May 1981". Did you personally draft this?

A. Yes, I did.

Q. And did you model this after any other resolution?

A. It's a — it's a composite model after many of the resolutions in that exhibit package plus some statements that would be specifically appropriate to the AGU.

Q. In this resolution or draft of a resolution it says, "science is the rational investigation of the physical world and its phenomena". Is that a definition of science to which you would ascribe?

A. That's a fairly accurate single sentence definition.

Q. What else would you add to the definition of science?

A. Well, if I had to broaden that a bit I think I would say that science is a system of thought or endeavor that attempts to determine the history and natural laws of the
 

38

physical world and its parts, and that it excludes supernatural causes. I think that would be a more complete definition.

Q. Is a definition of science a matter of science? Does it follow within a realm of science?

A. I think so.

Q. Or is it a matter of philosophy?

A. I think the boundary between science and philosophy is a matter of discussion for both disciplines but the definition of science is probably primarily a matter of — left to science. But I say that with the qualification I'm not a philosopher.

Q. On what basis do you define science?

A. I thought I just defined it for you.

Q. I'm — I'm not asking for your definition, I'm asking on what basis you have arrived at that definition? Have you taken it from somewhere else; have you formulated this yourself?

A. Well, throughout my career I've been exposed to various parts of the philosophy of science and I think parts of that definition you also find in Websters Dictionary. In order to practice science one has to know what it is.

Q. What do you mean by the term of rational investigation of the physical world and its phenomena?

A. In the sense that I used it there, I think it's probably, I mean a logical — logical use of physical facts.
 

39

Q. Is there a difference between science or what a scientific theory is to you?

A. Oh, yes.

Q. Could you describe the difference?

A. Well, science is the entire field of scientific endeavor. Scientific theory is one of the tools that scientists work with.

Q. What is a scientific theory to you?

A. A scientific theory is a framework for explaining a large body of physical data. And usually by the time that something becomes generally accepted as the theory there is a rather large preponderance of physical data to support it.

Q. I want to make sure that I got this correctly. A framework for explaining a large amount of physical data, is that what you said?

A. Yes. Connected physical data not random physical data. And I guess what I'm saying is that I don't know of any very tiny theories. Most of them tend to encompass large pieces of science.

Q. You state that science — in your resolution that, "the scientific method prohibits any and all appeals to supernatural or divine agents". What do you mean by the term, `appeal'?

MR. WOLFE: Excuse me. Is that a
 

40

quote?

MR. WILLIAMS: That is a quote. That is a quote.

MR. WOLFE: Could you indicate that on other parts that you are quoting in the future?

MR. WILLIAMS: Sure.

BY THE WITNESS:

A. What do I mean by the word, appeal?

Q. Yeah.

A. Well, I mean one is not permitted to call upon supernatural agents to explain what we see in the physical universe.

Q. You're not allowed to call upon them to —

A. You're not allowed to use those —

Q. — explain them?

A. You're not allowed to use those as an explanation of what we see.

Q. Does that mean that it did not occur?

A. No. That simply means that supernatural causes that science is not equipped to deal with.

Q. What is supernatural?

A. Well, anything that is not natural. Anything that can not be explained by physical laws. And I would include in that appeals to a deity, magic, voodoo, that sort of thing.

Q. When you look at what can be explained by natural law.
 

41

As you look down the road say twenty years from now, do you think that our concepts of what the natural laws are and our knowledge of the natural laws will have changed in those twenty years?

A. Well, if history is any indication of what is going to happen in the future, of course.

Q. We don't — we don't know about all natural laws do we?

A. Of course not. If we did, scientists would be out of business.

Q. So based on our present knowledge of natural law, might there not be things which today would be considered supernatural which as we know more about the laws would be — come into the realm of the natural law?

A. I suppose that's possible.

Q. I guess another way in saying that would be that in trying to explain the natural laws we're unfortunately limited by our own intellects.

MR. WOLFE: Is that a question. If so I object to the form.

MR. WILLIAMS: It is a question.

BY THE WITNESS:

A. Well, we're limited by our intellects, we're limited the extent to which we can observe things and we're limited by our ability to measure things. And I think those situations
 

42

are continually changing.

Q. Is there any distinction in your mind between a supernatural and the divine agent?

A. In the sense that it is used there and the sense that is used in most definitions of science, no. The divine agent would be included under supernatural and by that it only means things that are not concerned with physical law.

Q. On what basis have you made a or reached a conclusion creationism is a religious apologetic?

A. On the basis —

Q. Have you reached that conclusion?

A. Yes, I have. On the basis of reaching — reading the creationist literature.

Q. All right. Could you tell me what you understand religious apologetics to be?

A. It's a framework for expanding — explaining one's religious beliefs.

Q. Do you consider yourself to he an authority on religious apologetics?

A. No. I do not.

Q. Then on what basis have you concluded that creationism is religious apologetics?

A. Well, I looked up apologetics in the Webster's Dictionary and it seemed to fit what I had been reading in the scientific creationist literature.
 

43

Q. Are you relying on any — what you have read anywhere else besides Webster's when you make that statement in this resolution?

A. Well, that plus discussions with colleagues I suppose over things like scientific creationism.

Q. I'd like to show you a copy of Act 590 and refer you specifically to Section 4-a which is the definition of creation science. The 4-a (1). Do you see four by the definition?

A. Yes, I do.

Q. Could you tell me where within Genesis — a literal reading of Genesis that would be found?

A. No. I'm not that familiar with Genesis but there are specific references in some of the creationist literature to — to specific passages in Genesis.

Q. Is that essentially what you are relying on when you make the conclusion that creationism, to paraphrase, is an attempt to reconcile the universe with a literal interpretation of Genesis is — what — the statement you have seen in so called creationist literature, is that what you're relying on when you made this conclusion?

A. Well, yes. I think one has to, you know, if one is interested in knowing what chemistry is you have to study the literature and textbooks of chemistry and in doing so you learn what the subject of chemistry is about. The same is true in geology and I presume that the same is
 

44

true in scientific creationism. I have read within my limited capacity as widely as I could the literature I could get my hands on scientific creationism and I presume that that represents what scientific creationism is.

Q. All right. Have you read any data or read any reports or literature within the referee journals which support creation-science?

A. No. I have not.

Q. Are you aware if there is any?

A. As far as I'm aware, there is none in the trad — traditional scientific literature.

Q. If there were some would that change your opinion?

A. It would depend on how much of it there was and exactly what the evidence was.

Q. Your resolution also states, "it", referring to creationism, "attempts to explain scientific data within the framework of divine biblical revelation as interpreted by certain groups of fundamental Christians". In your reading of Act 590, is there any thing in there that indicates to you that this is biblical revelation interpreted by certain groups of fundamental Christians — funda— fundamental organizations?

A. Well, there again you use the word, creation-science, and I have to take the definition of creation-science from what — from what the creation-scientists provide me.
 

45

You can't define a branch of science in a — in a law. It has to be based on a body of knowledge and that requires literature and textbooks. And I examined what I could in their literature and that tells me what scientific creationism is.

Q. You are aware though, aren't you Dr. Dalrymple, that we're dealing here with creation-science as defined in Act 590 of the Acts of Arkansas?

A. Yes. I understand that. But this requires that you teach something and if it is not based on the traditional scientific literature and it is not based on the literature of scientific creationism then you have me confused. I'm not sure what it is you are going to teach.

Q. As you read Section 4-a which defines creation-science, and I'd like you to read that now and just take a moment.

A. Okay. Including the ones, and twos and threes?

Q. Right. You don't have to read it out loud. Just please tell me when you've completed reading it.

A. Okay.

Q. 4-a (1) states, "sudden creation of the universe, energy and life from nothing". Where to the best of your knowledge of Genesis is that found in Genesis?

A. I could not quote you where that is found. I am not a student of the Bible.

Q. 4-a (2) says, "the insufficiency of mutation
 

46

and natural selection in bringing about developments of all living kinds from a single organism". Is that dealt with anywhere in Genesis to your knowledge?

A. I have — I — I told you I'm not a student, of the Bible and I don't know if or where any of those things are dealt with in the Bible.

Q. Rather than belabor the point, if I read you 4-a (3-6) as well. Would your answer be the same as to where these portions of the definition are found in Genesis that you could not say?

A. I could not give you the chapter or the verse.

Q. Are they found in Genesis?

A. According the creationists, they are.

Q. According to the creationist literature that you have read?

A. According the creationist literature that I have read.

Q. I assume that you are not the only person in the country who utilizes potassium/argon dating or rubidium/ strontium — strontium?

A. That's correct.

Q. And you read other articles on those methods of dating, haven't you?

A. Oh, yes.

Q. Have you agreed with everything that you have read
 

47

in those articles professionally?

A. Not always.

Q. Do you think that each time you have read articles by other people on these methods of dating that they have always fairly characterized what potassium/argon dating is?

A. I think primarily they, yes, they have.

Q. Are you aware — well, my point and I think that you can see and the question that I was going to ask you is simply because someone uses a label for example of potassium/argon dating doesn't mean that they have used it correctly or that you would agree with them, does it?

A. Well, no. That's why we have scientific literatures so that we can read in detail what they have found and draw our conclusions from that. Otherwise the scientific literature would be a collection of opinions and that's not — that's not permitted. We are required to show the evidence and demonstrate how we reach our conclusions.

Q. When you look at scientific evidence is it reasonable as part of the scientific method to infer from scientific evidence? The general principle?

A. I guess I don't know quite what you mean by infer. Do you mean draw up tentative conclusions?

Q. Right. If that is what it means to you? I — I — I don't want to limit —

A. You know, that's what people try to do. They draw up tentative conclusions from their experiments.

[Off The Record Discussion.]
 

48

Q. I'm sorry. Could you read back that last statement?

[Thereupon the court reporter read back the last answer given by the witness.]

Q. This draft resolution states, "The religious doctrine of creationism has no place in any science curriculum." If there is scientific evidence for creation or for the other things included in Act 590, including a relatively recent inception of the earth, do you think that should be taught in a — can appropriately be taught in a public school science classroom?

A. Well, if and when such evidence were gathered and at such time when it became preponderant such that it was believable and was sufficient to overweigh the other evidence that suggests the contrary, then at that time and only at that time it might be an appropriate thing to teach.

Q. So only when it really overcomes evolution to use the term in the broad sense?

A. Well, that's the sense the creationists use it. I have never thought of myself or geology as being evolutionists. But if you're using it in their sense, yes.

Q. Well, let me say that we are dealing with Act 590 and evolution-science, as defined in the Act, does include an inception several billion years ago of the earth.
 

49

A. Several bil —

Q. Yes. Several billion years ago of the earth.

A. Okay.

Q. And that would be your opinion as to the age of the earth; is that not correct?

A. Well, it's not an opinion. It's a conclusion that myself and thousands of other scientists have drawn because the preponderance of evidence is overwhelming in favor of that conclusion.

Q. All right. So to restate, my understanding of your answer is that if there is scientific evidence for creation, it should not be taught in a public school science classroom until such time as it has a preponderance or a majority of the scientific community, or at such time as there is a majority of scientific evidence which supports it.

A. That's a little bit difficult to answer, but let me do it in the best way I can. I think that science classes should teach, as best they can, two things. One is the history of science so we learn the development of ideas. And the second is the present state of scientific knowledge. Now that has to be simplified so much because it's a very complicated subject and you can't teach all of it. Nobody knows all of it.

If any hypothesis, theory, model or set of facts
 

50

becomes supported by enough evidence so that it is generally accepted by the scientific community, then that assumption becomes part of science and it should be taught. But you see, we don't vote on these things. They become accepted by informal consensus.

And so when you say, you know, what if this happens? It's a little difficult to answer that question because we don't know what's going to happen. You see, at present there is overwhelming evidence that the earth is very old. It's virtually 100% of the evidence. Therefore, it is not a feasible hypothesis to propose or to teach as a theory or a hypothesis or anything else that the earth is only 10,000 years old. That's simply not acceptable.

Q. But as I understand your previous answer — and please correct me if I'm wrong — that you don't think that, for example, if there is evidence of a young earth that it should not be taught until such time as it, in effect, overcomes and replaces the evidence which says that the earth is old.

A. That's — that is typically the way that science works, yes.

Q. So for example, if there is a valid scientific theory in the sense that you have defined it and it's a minority scientific theory, you don't think it should be taught in the public school science classroom?
 

51

A. I don't think there is any such thing as a minority scientific theory and I will tell you why. Because by the time a hypothesis reaches the status of a theory, there has to be a preponderance of evidence supporting it. It has to be almost overwhelming. Now at some later date the situation may change so that that theory has to be modified. But in terms of a minority theory, I can't think of any. Sometimes you will get minority hypotheses.

Q. What's the difference between a hypothesis and a theory?

A. Well, a hypothesis basically has less, much less support than a theory and it often encompasses a smaller chunk of something.

For example, I might hypothesize that this table is six feet long and I might perform an experiment to determine whether that hypothesis is correct. But I don't think that would ever become a theory just because I proved the table is six feet long.

So there is a difference in both the weight of evidence, and there's usually a difference in scale.

Q. If you have a hypothesis which rises to the level of a theory, at some point is it possible for the theory to rise to the level of a fact?

A. I don't — well, the way I think of a fact is essentially an observation or a set of observations that
 

52

are virtually universally accepted. I think, again, a fact would be that this table is six feet long or however long it is. Now, that's kind of a personal definition. Usually in science we use things like hypothesis and theory. Facts are primarily a set of data. That's the way I think of fact.

Q. Well, trying to recall one of the more prominent examples from the history of science. When Copernicus hypothesized, I guess, first that we did not have a geocentric universe. But in fact, the planets revolved around the sun. And then at some point I suppose that was tested. Is that to you today a fact or a theory?

A. Well, I think that is sufficiently a simple concept and has been measured to the degree that I would probably consider that a fact. I don't know of anyone who disputes that.

Q. And that was, at one time, a theory was it not?

A. I presume it was, yes. I don't really know the history of evolution of that particular line of thought as well — well enough to tell you at what point it was a hypothesis and at what point it was a theory. I think today most people would regard the fact that — well, I just used the word didn't I? Would regard that as a fact that the planets go around the sun.

Q. All right. So to take your position that there is
 

53

no such thing as a minority view of scientific theory, at one time the thought that we do have a geocentric universe. The earth is the center around which everything else revolves. Did that hold sway in the scientific community? Are you aware of that?

A. As far as I know, that's correct.

Q. And when Copernicus offered this new theory or hypothesis, whatever you want to term it, it was not immediately and fully accepted within the scientific community. Are you aware of that?

A. That's correct.

Q. So under your view, until such time as the scientific community accepted, by a general consensus, Copernicus' theory, you would not have wanted that to be taught in a public school science classroom.

A. I think that depends on whether I were living in Copernicus' time or whether I were living today. If you asked me that — if that evolution and thought were going on today, I think we would recognize that Copernicus' hypothesis was a reasonable alternative that did not conflict necessarily with any data. And you might hold those two as an alternative hypothesis for a short period of time.

You do have occasionally some overlap when one theory or hypothesis replaces another one. There will be
 

54

a time when it is difficult to decide between the two.

Q. Uh-huh.

A. There is seldom one definitive experiment, one breakthrough that happens at an instant in time so that you switch instantaneously from one theory to another. The theory of plate tectonics, for example in geology took several years to become accepted and replace the old ideas. So there was a brief period of overlap.

Q. Uh-huh.

A. But it only becomes an alternative when it becomes a reasonable explanation and when it doesn't conflict with an overwhelming amount of fact that opposes it or data.

Q. Well, during the time that there was this overlap or when both were being discussed — both being these two theories of the earth and of the universe — would it have been useful for those students who were studying science to study both theories you think?

A. Well, I don't — I don't know. That's difficult because in those days science and philosophy were mixed up together and I think with religion, too. Degrees in science weren't given, I think, until after Darwin graduated.

I don't think you could go to school and study science and get a degree in it when Darwin went to school. So part of the difficulty in answering that question is because I think there's been an evolution in the way
 

55

science operates. It's separated from philosophy and religion in a way that it wasn't in Copernicus' time.

Q. The methods of radiometric dating which you have previously listed, are any of those methods — can two of those methods be used to date some geologic formation or rock or whatever — the same type? I mean can you use more than one method to arrive at a conclusion as to the age of something?

A. Sometimes you can, yes.

Q. Are the methods, to any degree, conflicting?

A. I don't quite understand —

Q. Well, is there a conflict in the methods of radiometric dating?

A. I still don't know what you're —

Q. Can you answer the question? Is there a conflict?

A. Well I don't understand the question. That's why I can't —

MR. WOLFE: I guess I find the question ambiguous as well. I'm not certain whether you mean do the methods they use, are in some sense not the same? Are they conflicting? Or are you asking whether the results arrived at, whether they occasionally give conflicting dates, for instance. I'm afraid I would object to the form of the question as presently posed as ambiguous.
 

56

Q. All right. Let me see if I can rephrase it. Let me ask maybe a different question. Are you aware of generally some of the theories of evolution?

A. Only in the most general sense and primarily as a layman.

Q. All right.

A. I'm not prepared to answer any detailed questions on evolution at all. It is out of my field of expertise.

Q. Are you aware that there is something called the modern synthesis theory of evolution?

A. I'll just have to repeat my previous statement. I'm not an expert on evolution. I'm —

Q. I'm not asking you — I'm asking you as a layman are you aware — a layman in that field are you aware of that?

A. No.

Q. Are you aware of something called the punctuated equilibrium?

A. I have heard about it, yes.

Q. What do you understand that to be?

A. Well, my understanding is that — again, this is a layman's interpretation — is that evolution proceeds by a series of spurts and then long periods of stasis or non-change.

Q. And that is opposed — that theory would be as opposed to a slow gradual change; is that correct?
 

57

A. That's my general understanding, yes.

Q. Do you know as to whether one is held by a majority of people within this field of expertise or not?

A. You'd have to ask a biologist. I don't know that.

Q. Basic mathematics would tell you that both can't be held by a majority. Would you agree with that?

A. Both could be held as alternative explanations, alternative models until such time as there is enough evidence to decide which is which. I'm speaking now in a general sense.

Q. I understand.

A. I don't know about these specific things at all.

Q. Sure. Do you think it would be appropriate in a public school science classroom to study both of these theories?

A. Well, you're really asking me now I think what the — a question that's related to what the present state of biological science is. And I'm not sure enough of what that is. I think that science classes should teach the present state of science as it is perceived by scientists. Now I don't know whether scientists perceive those as being equal or whether more people are in favor of one or the other. So it is difficult for me to answer the question if that's enough of a qualification to explain my difficulty.

Q. Okay. If there is one that is held by more of a
 

58

majority of scientists and one that is held by a minority of scientists, do you think that the minority view should not be discussed in a science classroom?

A. Well, I suppose that depends on why it's a minority. If it's a minority because it's absurd, then I think it should not be discussed in the classroom. If it's a minority simply because there is slightly more evidence for one than the other and perhaps you have 60% of the people thinking that one may be correct and 40% thinking that the other is correct, then I would suggest that those things probably, then, should be both discussed in a classroom.

Q. Doesn't that conflict with your previous answer that there's no such thing as a minority scientific theory?

A. No, it doesn't. I think I said at time of transition when one theory might be replacing another one or when it is difficult to decide between the two, there may be periods of overlap. But I think those are rare. I'm not even sure that either one of those models has the status of a theory.

Q. Why do you say that?

A. Just because of my own ignorance. I'm not saying they don't have that status. What I'm saying is I don't know what the status of punctuated equilibrium versus gradual and continual evolution is. This is out of my

field.

Q. Was your earlier answer, though, to one of my questions that if a hypothesis is held by only a minority of the scientific community, then it cannot be a scientific theory?

A. Would you repeat that for me again?

Q. Okay. Let me rephrase it. I have it down earlier that you said there's no such thing as a minority view scientific theory.

A. I think I later qualified that to say that at times, perhaps, there might be.

Q. Now how do you define — how does science define when there is an overlap, this transition that you mentioned?

A. Well, usually when there's active debate on both models in the traditional literature then there's an overlap. When science has a difficult time deciding between two models or two hypotheses, that's usually fairly obvious because the literature reflects that disagreement or that uncertainty.

Q. So if there is an overlap, do I understand you to say that you would not, at that point, object to two perhaps conflicting theories being taught in a public school science classroom?

A. No, provided they're both scientific theories or hypotheses and provided they're both substantiated with
 

60

enough fact or observation that they — that both should be taken seriously, at least to a degree. Then I wouldn't object at all.

Q. Well, that last qualification you put on there of — of — could you read that back? That last part of that statement.

[Thereupon the court reporter read back the last answer given by the witness.]

Q. Okay. If there is a debate or publications in the scientific journals on both, would that not be sufficient evidence to you that there is enough facts or evidence for both as you said there?

A. Not necessarily. Every once in awhile a scientist will get an absolutely crazy idea and, publish it in the scientific literature as, uh, "Here's my crazy idea, colleagues. What do you think about it?" Just because that paper appears in the scientific literature does not give it the status of a hypothesis.

I think hypotheses have to be — have to be reasonable. They have to have some reasonable chance of being true before they're worth spending much time on.

Q. How do you define whether they're reasonable?

A. Well, when I think enough scientists look at that and say, "Yeah, that's a possibility." May I use an example?
 

61

Q. Sure

A. I think today if a scientists published a hypothesis that said that the earth was flat, I think we now have enough data and have had enough data for so long that that's absurd. Now you could frame that proposition in terms of a scientific hypothesis. But it really is not because it's absurd and because it is so totally disproved.

Q. Let's go off the record.

[Off the record discussion.]

BY MR. WILLIAMS:

Q. Dr. Dalrymple, do you favor teaching all scientific evidence on theories of origins?

MR. WOLFE: I'll object to the form of the question unless you specify whether it's to high school students, graduate students, whatever.

MR. WILLIAMS: Oh. I really want to find out generally. I think we can qualify it later of if he wants to qualify it, he certainly can. But I want to — let's say generally teaching all scientific evidence.

MR. WOLFE: Well, then I want to object to the question.

Q. Okay. You can answer the question.

A. I guess I need to know before I do that what you mean by origin?
 

62

Q. Talking about theories of origin of the universe, the earth, of life and man.

A. You don't necessarily mean ultimate origin? You see, this is the problem I have. If you ask me how a particular rock originated in its present state, that's a fairly simple question. It might be scientifically complex, but its a fairly simple question. If you're asking me how matter and energy came into being in the beginning, whatever that means then that's a difficult question that I'm not sure is within the realm of science. So that's my difficulty.

Q. Well, please remember that in my question it's a given that we're talking about scientific evidence.

MR. WOLFE: Well, I'll object to the form of the modified or restated question because it may not, in fact, be possible to assume that there is scientific evidence on a — on a, by definition, a non- scientific question.

A. You know, there's scientific evidence that goes back to the "Big Bang" if I can use that phrase. It doesn't go beyond that.

Q. Well, for example the scientific evidence on the Big Bang. Do you think that should be taught or do you favor it being taught?

A. Yes. Yes. Those are scientific observations.
 

63

Q. What is the scientific evidence of which you are aware which supports the Big Bang theory?

A. Well, you're asking a question in astronomy and astrophysics and this is, again, out of my field. So if you want an answer, it would have to be a layman's answer. And as far as I know, the ideas or the data are primarily based on the fact that the galaxies are mutually receding away from each other and away from a common point in the universe.

Q. What happened to your resolution after you drafted it and circulated it?

A. Well, there's been no action on it yet. It has not been introduced to the council. I don't know whether it will be introduced to the council.

Q. Have you had a meeting of the council?

A. There's been no meeting.

Q. I take it you did get some opposition to your resolution?

A. Basically to the wording. This draft was circulated to try to find out whether there was enough interest in the subject that a resolution in any form should be considered. And this is why I say I'm not sure the resolution will even be introduced.

I think I would also like to say that that is a rough draft. It has the same status as an unfinished
 

64

manuscript and I fully expect that if it goes anywhere, it will be modified. I don't know in what way except that there'll be other people besides myself involved in it. They will have opinions of their own on how such a resolution might be worded.

Q. In some of your letters in here you state that if it should be defeated and not prevail or be defeated, you told the council that that would be, to paraphrase, disastrous. Why is that?

A. Well, I wouldn't use the term disastrous, but my guess is that the creationists would view that as a victory. That a scientific society has considered a resolution against scientific creationism and rejected it. In a sense, whenever you submit a resolution like this you are forcing a group to take a stand either yes or no. There is no in between. This is why I say I'm not even sure it will be introduced because I'm not sure they even want to consider the question. It maybe a subject in which there is not interest. And if that's so, it will be promptly dropped.

Q. Why would there perhaps be no interest in your opinion?

A. There is a — there are some people in the AGU who do not think that the AGU should become heavily involved in any public issues. That it should stick primarily to
 

65

the dissemination of scientific information strictly for the consumption of scientists.

Q. Uh-huh.

A. And I anticipate that might be the major objection of considering such a resolution.

Q. In one of your letters, this one to Dr. Leslie Meredith, you state that "We..." and from the context of the letter-I think that's Carl Sagan and yourself.

A. Uh-huh

Q. "...think that this is appropriate for the AGU to go on record on this issue, particularly as it is primarily a science education issue and not a political one." Could you tell me why you feel it is a science education issue and not a political one?

A. Because I think the issue is really what is going to be taught in science. That's the only issue that concerns me. I'm only concerned with science education. I have no qualms or reservations about teaching creationism as part of a social science curriculum or as part of a religion curriculum or a philosophy curriculum. But I have objections to teaching it as a science curriculum because I sincerely believe it is not science. That's why I think this is primarily an issue of what is science and what is not science.

Q. You wrote a letter, according to Exhibit #3, to
 

66

Dr. James A. Van Allen. Did you ever get a response from him on this?

A. No, I've not yet.

Q. Have you talked with him about it?

A. I've not.

Q. One of the letters that you did receive from someone by the name of C. T. Russell and he says that he thinks that Van Allen will be your main problem. Do you know why he has that opinion?

A. No, I don't.

Q. According to this letter, Van Allen strongly opposed the ERA resolution. And do you know from that — are you aware of that fact?

A. Yes, I'm aware of it. And my understanding of that is that Jim Van Allen is opposed to the AGU taking stances on public and political issues. And whether he would consider a resolution on creationism to be one of those or not, I will not know until I hear back from him or have. a chance to talk to him in person about it. The letter by Russell is obviously speculation based on what, I don't know.

Q. Let's mark this as Defendant's Exhibit #4 please.

[Thereupon State's Exhibit #4 was marked for the record.]

Q. I'd like to show you Exhibit #4 to your deposition
 

67

which is a letter to you from someone and your letter to a Sister Neal I think it is.

A. Noel.

Q. Noel? Excuse me. Do you recall writing that letter?

A. Yes. I recall writing one of the letters. I think she wrote the other one.

Q. Why did you write the letter to Sister Noel Riley?

A. She had written a column in a Southern California newspaper. I believe it was the Los Angeles Times but I'm not sure. I thought it was very well done and I wrote to her to tell her essentially that. She wrote back telling me basically that she appreciated my letter.

Q. All right.

A. I often do that when people have done things I like. I will often write them and say, "Congratulations" or "I think that was fine." "I appreciate what you've done" and so forth. I try to make that a regular habit.

Q. You stated in your letter to her that "Fortunately the number of scientists who draw religious inferences from physical data and the number of religious leaders who use the Bible as a science text are very small minority."

A. Yes.

Q. Who are the scientists of which you are aware who draw religious inferences from physical data?

A. I'm not aware of any in my personal knowledge. Those
 

68

were phrases taken out of her column. I don't personally know any who do.

Q. Do you know of any who do?

A. I do not know of any who do and the reason I phrased it the way I did is I'm perfectly willing to admit that there may be some. She, as I recall, said there were and I'm quite willing to grant that possibility. But from my experience they must be a very small minority because I don't know any of them.

Q. Do you recall what she was talking about and what kind of inferences, religious inferences scientists were trying to draw from physical data?

A. I don't recall the details of the column at all.

Q. Do you have an opinion as to whether religion can be based on science?

A. I'm not sure I have any opinion on that one way or the other. Let me think about that a minute. I guess the answer to that might depend on how religion was defined.

Q. How do you define religion?

A. Well, my — I guess my personal definition is belief in a supreme deity of some sort, or deities.

Q. Do you think it's necessary to have a supreme being or God in order to have a religion?

A. Well, within my upbringing in western culture, I guess the answer to that would be yes.
 

69

Q. You mentioned western culture. Would you acknowledge that there are religions, particularly some of the eastern mystic religions which don't have a God in a sense. Are you aware of that?

A. No, I'm not aware of that, but I'm willing to take your word for it if you say it's so.

Q. Okay.

A. I'm not a student of religion.

Q. You also used the phrase "religious leaders who use the Bible as a science text."

A. Yes.

Q. Does your reading of Act 590 indicate to you that the Bible could be used as a science text under this law?

A. May I look at this?

Q. Certainly.

A. Well, it says that the teaching must not include any religious instruction or references to religious writings. And I would presume that would preclude using the Bible as a text.

Q. Mark this Exhibit #5 please.

[Thereupon State's Exhibit #5 was marked for the record.]

Q. Let me show you Exhibit #5 which is a letter dated June 4, 1981 to Niles Eldredge from you and I believe there is another letter attached as part of that exhibit which
 

70

is from Niles Eldredge to you.

A. Uh-huh.

Q. Do you recall those letters?

A. Yes. I wrote them if that's what you're asking.

Q. What are the geophysical issues as you use that term in here as they relate to science and creationism?

A. Well, creationism has two geological propositions. One is that the earth is approximately 10,000 years old or less and the second is that all the sedimentary rocks in the geologic column were deposited during the great flood which lasted about a year and occurred sometime between 4,500 and 7,000 years ago. Those are the two propositions against which there is a preponderance of geophysical evidence.

Q. I'd like for you to look at Act 590 and tell me where the first of those propositions that the earth is approximately 10,000 years old is found in Act 590 if it is.

A. Well, it's not. But Section 4.(a)6 says, "relatively recent inception of the earth and living kinds." And from reading rather extensively in the scientific creationism literature, all of those writings seem to indicate — or most of them seem to indicate that the earth is less than 10,000 years old. There are numerous statements to that effect.

Q. However, as you personally understand the term
 

71

"relatively recent" given the age which you believe the earth is of some like 4.6 billion years old, "relatively recent" could mean a lot older than 10,000 years old couldn't it?

A. It could but I don't think you would get any scientific creationists to accept that definition. If they would, I've not seen it written down by them.

Q. Is there scientific evidence that the earth is, while older, than 10,000, is younger than 4.6 to 4.8 billion years old?

A. None that I know of.

Q. In Niles Eldredge's letter to you he states, "Your manuscript told me something, with crystal clarity, that (though I knew) I had been sweeping under the table: I have been fond of saying that creation science isn't science — but this is not strictly accurate." And he goes on to talk about that creation-science is science, but it is what he says is "bad" science. Is that your opinion?

A. Well, my opinion is that it's not science because it's religiously based. I think what he was talking about was the kind of treatment I did in here (indicating). In the introduction I said that there were two geological corollaries of what they call their creation model. And we can examine those as if they were hypotheses and see
 

72

whether they are absurd or whether they are reasonable.

Q. Uh-huh.

A. So often times you can treat things scientifically without them necessarily being science. Now if you look at these as religiously based, it's not science. If you divorce it from the religion, then it only becomes absurd. This is what I think he probably means by "bad" science. If you really want to know what he means in that letter you'd have to ask him.

Q. Well, earlier I think in discussing your draft resolution we talked about what was science and what was a scientific theory. And your resolution made statements about that a theory must be testable, capable of validation, that sort of thing. Now if you look at, for example, the statement that there has been a relatively recent inception of the earth and living kinds. Let's just take the portion dealing with the earth since that's really your area of expertise as I understand it.

A. Yes.

Q. What you are, in effect, I think saying here in this manuscript is that aspect of creation-science is subject to being tested and you have tested it and think it's false.

A. It's been tested. We've known for over 25 years that the earth was 4® billion years old and the solar system. And at this point, to say that it's very young regardless
 

73

of whether you draw that line at 10,000 years or 1,000,000 years or even 10,000,000 years, it is an absurd hypothesis. It is in the class of the flat earth.

You see, when things become absurd they cease to be science. We simply can't afford to waste our time reproving things that are already proven.

Q. Now you've added another qualification I think to what is a scientific theory. That is that it must not be absurd.

A. Well, I think I said before that a theory had a preponderance of evidence to support, even though it was still undergoing tests and may undergo modification. I think what I said earlier was that a hypothesis may not be absurd. I think the same thing holds true of a theory. A theory may not be absurd.

Q. And it goes without saying that if it is absurd, it's not a scientific theory or hypothesis in your mind; correct?

A. I think that's a fair statement, yes.

Q. Who is to determine the absurdity of a theory?

A. Well, that's generally done by a collection of scientists, by consensus. There is no formal procedure for doing that.

Q. So that if someone says — a consensus or majority of scientists say a theory is absurd, then at that point the scientific community can dismiss it and not consider
 

74

it further as a viable scientific theory?

A. That's basically correct, you see, but that's not just based on an opinion. People would come to the conclusion that it's absurd because they know of an overwhelming amount of evidence against it. That's what makes it absurd. It's not really a matter of opinion. It's a matter of evaluating the evidence.

Q. And you state in your letter to Eldredge that "Hypotheses that are clearly false, like above or a 10,000 year-old earth, are not scientific hypotheses — they're silly and the produce of emotionally and intellectually retarded minds." Is that an accurate representation of your beliefs and your feelings?

A. I wrote that, yes.

Q. So that anyone who believes in an age of the earth which is 10,000 years old is retarded?

MR. WOLFE: I will object to the characterization that counsel has just used. The letter was read into the record. The witness was asked whether he had, in fact, written it. He did say that he had, in fact, written it and I believe that it speaks for itself.

MR. WILLIAMS: The characterization is the witnesses, not counsel's.

MR. WOLFE: No, no. The
 

75

characterization is clearly that of Mr. Williams. The letter is clearly that of Dr. Dalrymple. And I think the record now is perfectly clear as to that distinction. I suggest that you made an effort to blur that distinction, which I prefer you not to do.

Q. Well, let me make sure that the record is perfectly clear. It is your belief that anyone who thinks that the earth is approximately 10,000 years old has an emotionally and intellectually retarded mind?

A. Well, I wrote that and those terms are used very loosely. This was a personal conversation between two people. If I may rephrase it a little bit, I think that people who attempt to put that proposition over as science rather than a personal belief or a personal religious belief can't be very bright because there is a tremendous amount of scientific evidence. Thousands and thousands and thousands of data which tell us that is not true. It's absurd. And they simply can't understand that. Therefore, there is something wrong with their process of thinking scientifically. I'm only restricting that to scientific reasoning. I have no qualms about what people choose to believe as religion or philosophy or anything else. As a scientific proposition, it's absurd.

Q. Do you agree or disagree with this statement? This is from Eldredge. "So, when the ACLU says that the
 

76

Arkansas law injects religion into the school curriculum, they're right, but they must avoid asserting that creation- science is pure religion. It's science — bad, bad science."

A. Well, I think there are two ways to look at that. It's hard to say whether I agree exactly with that or not. But scientific creationism is clearly religiously based, and in that sense, it's an introduction of religion into science teaching. On the other hand, if you want to try and divorce that and look at it as science, it is rotten, rotten, science. So there are really sort of two ways to look at it. I don't think we want to teach rotten science.

Q. He goes on to state, "But, unfortunately, it is not unconstitutional to teach bad science." Without asking for a legal judgement, do you agree with that?

MR. WOLFE: I would object to the form of the question. I would like to have some greater specification of whether there is any content to that question that does not call for a legal judgement.

MR. WILLIAMS: Okay. I think that's fair. I think that's probably inherently legal. WITNESS: I was going to say that the Supreme Court has enough trouble with that. I don't know why you're asking a poor geologist.

BY MR. WILLIAMS:

Q. This manuscript which we've previously discussed,
 

77

for purposes of this deposition, why don't I have this marked as Exhibit #6. I don't want to make it an exhibit to the deposition, but just marked for identification. [Thereupon State's Exhibit #6 was marked for identification.]

Q. As I understand it, is Exhibit #6 going to be part of a book or is it going to be published as a book itself?

A. The present intentions are that it will be a chapter of a book.

Q. Who, if you know, are going to be the authors of the other chapters?

A. I'll try to remember who they are. Bill Mayer, Norman Horowitz of Cal Tech, Richard Dickerson of Cal Tech and I believe Tom Jukes of Berkeley, plus myself. There may be others that I've forgotten. There is one more. Everett Olson of UCLA.

Q. And is Mayer going to be the editor?

A. He has taken the responsibility of editing the volume, yes. The scientific editor.

Q. Do you know who he refers to in "our brave little band"?

A. I think he's referring to the people who were supposed to be the scientific witnesses in the Segraves trial for the State of California.

Q. I notice you have in here some correspondence which
 

78

appears to be from Kelley Segraves. How did you come to have this correspondence?

A. That was sent to me by Tom Jukes if I recall correctly. Is there a letter attached to the front? I'm not sure but that came in a — I think that came from Tom Jukes. But I'm not sure.

Q. Do you plan to rely on this in your testimony?

A. No, it was put in there simply because it seemed to fit the description of the material that you asked for.

Q. Mark this please.

[Thereupon State's Exhibit #7 was marked for the record.]

Q. I show you what's been marked as State's Exhibit #7 to your deposition, which is a memorandum dated September 25, 1981 to the Assistant Chief Geologist, Western Region. from the Acting Assistant Director, Western Region.

A. Yes. Uh-huh.

Q. Do you recall receiving this document?

A. Yes.

Q. Was there a document which you sent to — is it Mr. Swinnerton —

A. Swinnerton.

Q. — in which he, in turn, gave you this one? I note Exhibit #7 says, "As requested, you are authorized to testify. . ."
 

79

A. Yes. I wrote him a letter stating that I had been asked to testify by the ACLU, gave him the case number and so forth; and I could not find that letter. But it was a simple standard form request for permission to testify.

Q. Could you tell me what you understand to mean by this, the following language in his memo to you? "You are not authorized to testify on behalf of either party. However, you are authorized to present factual data and furnish records in regards to radiometric dating."

A. What he means by that?

Q. What you understand that to mean, particularly that first sentence.

A. That's basically I'm authorized to
