Methods of Logic Author:Willard Van Orman Quine from the preface: — This book understakes both to convey a precise understanding of the formal concepts of modern logic and to develop convenient techniques of formal reasoning. Logic books exist which are strong in theory and rigorous and elegant in the matter of proofs, but the reader who would discover further proofs on his own has had painful... more »ly to develop his own method of discovery. In this book, though rigor has been preserved, the objective of inculcating technical difficulty has been allowed to prevail over that of elegance.« less
