The work of which this is an English translation appeared originally in French as Precis de logique mathematique. In 1954 Dr. Albert Menne brought out a revised and somewhat enlarged edition in German (Grund riss der Logistik, F. Schoningh, Paderborn). In making my translation I have used both editions. For the most part I have followed the original French edition, since I thought there was some advantage in keeping the work as short as possible. However, I have included the more extensive historical notes of Dr. Menne, his bibliography, and the two sections on modal logic and the syntactical categories ( 25 and 27), which were not in the original. I have endeavored to correct the typo graphical errors that appeared in the original editions and have made a few additions to the bibliography. In making the translation I have profited more than words can tell from the ever-generous help of Fr. Bochenski while he was teaching at the University of Notre Dame during 1955-56. OTTO BIRD Notre Dame, 1959 I GENERAL PRINCIPLES O. INTRODUCTION 0. 1. Notion and history. Mathematical logic, also called 'logistic', .symbolic logic', the 'algebra of logic', and, more recently, simply 'formal logic', is the set of logical theories elaborated in the course of the last century with the aid of an artificial notation and a rigorously deductive method."

The three books presented in this volume, Integral Humanism, Freedom in the Modern World, and A Letter on Independence, were all written in the early 1930s, a time of dire trouble for France. France was then surrounded by enemies preparing for war and was itself so violently split between parties of Left and Right that it seemed on the verge of civil war. In this collection, Jacques Maritain accepts the responsibility of a Christian philosopher to actively address the agonizing practical problems of the time. Maritain discusses major political issues such as the relation of freedom and religion, the opposition of democracy to any form of totalitarianism, the relation of the spiritual and the temporal, the need for an integral and Christian humanism, and the prospects for a new Christian civilization, all in opposition to the materialism of both communism and capitalism. Against the fierce antagonism of the parties of the political Left and Right, Maritain declares a plague on both their houses and strongly affirms the need for independence from both of them. He does so by distinguishing between two senses of the terms Left and Right, one denoting a temperamental or physiological disposition, the other a definite political position. In the latter sense, Maritain asserts that he is an independent, while acknowledging that he is, by temperament, a man of the Left.
