is not Aristotle's.
He never said it in any form.
So much like all these phrases we have in the USA with regard to quotations from "Ben Franklin". Who knows if he said any of these things.

Re: A = A - Interesting That This "Law of Identity"
The reason I suspect it's attributed to Aristotle is because he argued often in the same manner. For example:xerosaburu wrote:is not Aristotle's.
He never said it in any form.
From his work Metaphysics IVAristotle wrote:It is impossible for the same thing to belong and not belong simultaneously to the same thing in the same respect (...) it is impossible to be in error about it.
From his work Prior Analytics - Book II: Chapter 2Aristotle wrote:First then that it is not possible to draw a false conclusion from true premisses, is made clear by this consideration. If it is necessary that B should be when A is, it is necessary that A should not be when B is not. If then A is true, B must be true: otherwise it will turn out that the same thing both is and is not at the same time. But this is impossible.
