Must logic exist?

[Anomalocaris]

Yes logic must exist, you would need a logical framework within which to prove logic does not exist, so therefore logic would be a necessity.

Why is proving whether logic exist a necessity? If existence of logic is a topic of no concern, why must logic still exist? Where was logic when cynobacteria ruled the earth?

[Edwardo Piet]

If logic is to be defined as just the concept of logic, then without the concept of logic, logic doesn't exist at all.

If logic is to be defined as the totality of all logical things, then logic exists if anything exists at all.

Is it possible for logic to not exist? Must it exist?

If logic doesn't exist then, logically, that means it doesn't exist.... but since that logically means it mustn't then isn't that logical so therefore it must?

Logic as traditionally understood is an examination of arguments. No one to make the argument, no logic. No one to examine the argument, no logic. If there is everything else, except one to make or examine the argument, still no logic. Everything else might still be logically comprehensible if there were logic, but that by itself is not enough to conjure logic into existence.

What about logical absolutes?

A rock is still, logically, a rock, whether anyone is around to conceive of the concept of logic or not.

If there weren't anyone to conceive of the concept of logic, then rock might still be a rock, but it wouldn't logically still be a rock.

Without logic there is no framework to make comparitive statements so even the statement, "There is no logic." Can't be logically understood without logic, and yes the tree makes sound even without a perceiver.

A rock must be a rock, not might, and it must logically be so: Because the alternative is for it to illogically be a rock which would require it to not obey the Law of Identity and hence, not actually be a rock which is a self-contradiction and impossible.

It doesn't matter whether it might or must be a rock. It is not logically a rock unless someone is there to form the logic.

[Edwardo Piet]

A rock is either logically a rock or illogically a rock. Since illogical means not logical. How can a rock illogically be a rock if that would require it to disobey the Law of Identity and so not be a rock?

So the new question should be, "Is logic an intrinsic quality of reality or is it an artifact of the interaction between the perceived and the perceiver." I believe that logic is an intrinsic quality of reality, much like an inch is a measure of distance intrinsically present regardless of whether it is measured or not. If a tree falls in the woods it causes all things relating to sound even if nobody is there to perceive that sound.
