W.V.O. tried to prove that no statement is necessarily true. In this work, Quines argument is stated, analyzed, and shown to be a broken argument for a false conclusion. The role of necessary truth in scientific procedure is then discussed. It is then shown that necessary truths are no less integral than empirical truths to the empirical sciences- and it is thereby rigorously demonstrated that, in addition to being false, Deweys pragmatism, Wittgensteins verificationism, and Comtes positivism, are so thoroughly incoherent that any clear statement of them amounts to a refutation of them.
