A Brief Introduction to Propositional Logic
... • If the truth value of a sentence is 1, the truth value of its negation is 0. If the truth value of a sentence is 0, the truth value of its negation is 1. • The truth value of a conjunction is true if and only if the truth value of its conjuncts are both true; otherwise, the truth value is false. • ...

Inquiry
An inquiry is any process that has the aim of augmenting knowledge, resolving doubt, or solving a problem. A theory of inquiry is an account of the various types of inquiry and a treatment of the ways that each type of inquiry achieves its aim.
