Quote (Petrushka @ Feb 14 2012, 14:37)
I accept the definitional foundation of logic.

I also accept the findings of physics which make the concept of physical existence rather complicated. That just means that physical is not the same as the ideal, just as a physical circle is not an ideal circle.

I thought this was something generally agreed upon. I thought it was the foundation of Platoís thought.

But to answer the specific question, in formal logic, the moon cannot both exist and not exist.

The question faced by physics is somewhat different.

UD Moderator: Thatís not ďnoĒ Petrushka. Goodbye.
