Just the basics: This T-shirt carries a formula of symbolic propositional logic exemplifying the law of the excluded middle. In English, the symbols read as, for some proposition P, "either P or not-P". It's similar to saying that any claim is either true, or its negation is true. An axiom of classical logic, some other systems of logic do not require this.
