@GrantGooch@MartinusLogicus That's tricky, because many shapes that were thought impossible to exist were made, such as in non-euclidean geometry.
A contradiction works for propositions. Reality is not just propositions.
@reubsey@radiofreeautumn No faith at all.
Logic is simply a formalization of cognitive process. I don't have faith in them, in the same way I don't have faith in vision.
@reubsey@radiofreeautumn Sure.
The fact is that logic can't be proven, because any proof presupposes it. That's why Aristotle called the principle of non contradiction an axiom.
@reubsey@radiofreeautumn Ad hoc like your god?
Where is the contradiction in something self evident? SPOILER: There's not.
Also, the fact that logic is possible is not a methaphysical claim, it's an experiential one.
You are conflating a lot of things. I guess you never actually studied philosophy.
@reubsey@radiofreeautumn Logical reasoning is experientally happening. Therefore it's self evident like touching a tree.
Abstract semantic games don't provide any stronger justification.
