Uncommondescent has established a shiboleth for commenters: They must answer the question, "Can the moon exist and not exist at the same time and in the same formal relation?" And the only answer that will be accepted is "No." I read the first answer by the ID critic, Petrushka:
"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
I thought this was something generally agreed upon. I thought it was the foundation of Plato’s 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."
That sounded like a fairly reasonable answer to me. However, the moderator didn't see it that way, and Petrushka was banned. So I thought I would extend an invitation to Petrushka and all other commenters who have been banned from UD: You're welcome to comment here.
By the way, if you don't find my posts interesting enough to comment on, feel free to recommend another topic. If I find it interesting, I'll post something, and then you can comment on it.
