There are some who confine logic to the consistency of sets of
statements and the validity of inference, and others who mix it up
with metaphysics. I belong to the former camp.

The law of identity is a property of statements, not things.

CB: So, there is no law that a thing must be identical with itself ?

How can I get a copy of your book ?
Why is it important to have a law that entities in statements are
identical with themselves, but no similar law for actually existing
things ?

Probably the most widely used ones are the books
Irving Copi's including his book,
Introduction to Logic
www.amazon.com/Introduction-Logic-Irving-M-Copi/dp/0130102024
and his, Symbolic Logic
A=A is not static.
BTW, as a Trotskyist, Copi was subject to McCarthyite persecution,
but I think he squeezed through by sticking to logic. Anyway, it's
all in George Reisch's book.

A remains A. That's static. A turning into its opposite is change.
