Confused? How can that be? This is at the root of logic. Should be easy.

The law of identity, A = A

The law of contradiction, A cannot be both A and not A

The law of the excluded middle, A must be either A or not A

Proof? How can you ask that? This is at the root of logic. Should be easy. Cool

Well, what is your proof for the very basis of logic? It's pretty basic you know. Without proof anything goes.

Because A cannot be what it is not, and you must choose what you want to live by.

That's an argument (not proof) for: A ≠ ¬A

The only proof for it is itself.
Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day
