JustinLK reacted to a post in a topic: What logical systems categorize A->~A as a contradiction.?

O.k. so if I understand correctly, essentially "A->~A" is a proposition, and NOT the same as saying "A is not A", which is simply stating a contradiction- that if A exists, then not A exists (and therefore a contradiction). I think I was equivocating the use of the boolean value of A in propositional logic with the axiom of A is A (in which case A is always true).

Hello, I'm new to this forum and discussing philosophy, and would like to hear some thoughts. A post on the philosophy stack exchange forum had the following posed http://philosophy.stackexchange.com/questions/23180/what-logical-systems-categorize-a-a-as-a-contradiction As of this moment, I haven't seen an objectivist weigh in. Unless I'm reading this wrong, it seems to be throwing theories around right in the face of the objectivist philosophy, and the axiom of existence exists (A is A). Isn't objectivism a logical system? Am I missing something here? Has everyone on that forum drunk the anti-axiomatic Kool Aid? Thanks, Justin
