|That's the basis for comment to Eric: it's a tautology in the same way as e=mc^2.|
Which is to say, not a tautology at all. "Survival of the fittest" would be a tautology only if biologists defined the "fittest" as "those who survive". E=mc2 would be a tautology only if m were defined as E/c2. Physicists don't define m in that way, and so E=mc2 is not a tautology.
|It's a production, and equivalence for sure, but it's based on reality-grounded, empirical principles (and both are falsifiable).|
Right. It just seems odd to me that you would call it a tautology when it's falsifiable. "A falsifiable tautology" is an oxymoron. To use the classic example, we don't need to examine a single actual bachelor in order to determine that "all bachelors are unmarried" is a tautology. It's true by definition.
