Incidently, the mid-20c school of thought called "General Semantics" held that A != A (or at least not always), and their logo was an A with a bar over it; I think it may have helped inspire the early cognitive psychologist Albert Ellis to invent a new language called E Prime which was simply English with all forms of the verb "to be" removed. He is supposed to have written one book in E Prime, and as far as I know that was the end of it.

Anyway General Semantics preceded Ayn Rand, so maybe it ticked her off.
