Professor Bochenski, as he himself points out in the prologue, is a logician; he is best known in England and the United States for his work in the history of logic, and more recently in Soviet and East European philosophy. But he has taught philosophy for many years - in Rome, in Switzerland, and on a number of visits to the United States - and in this book provides an elementary introduction to contemporary work in the field. As a means (...) to this end he has chosen to deal with four alternative methods employed by philosophers in the twentieth century. Philosophical methodology has not attracted much attention, in English speaking circles, as a distinct branch of the discipline of philosophy; the term "methodologist", if used at all, would ordinarily be taken to refer to somebody concerned with scientific rather than philosophical method. When, therefore, Professor Bochenski refers, as he frequently does, to "contemporary methodologists", meaning people who debate the re spective merits of phenomenology and mathematical logic as ways of approaching the world, the phrase has an odd ring. But philosophical methodology really makes a great deal more sense than scientific method ology. In science methodology is almost superfluous; given all the avail able information and a reasonably clear idea of what is wanted, there is usually not much ambiguity as to the means of getting it, or not much that could be resolved by mere argument.

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. 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, 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 aim of the present paper is to present a logical analysis of the concept of the free society. The symbolism used will be that of the Principia Mathematica—a few extra-logical symbols being explained when introduced. Regarding logical symbolism, it must be stressed, that the use of artificial symbols is not to be understood as a formalization. For formalization is a procedure by which one abstracts from the meaning of terms and operates on the shapes of the symbols alone—which will (...) not be done here. The symbolism is rather used as a useful shorthand, without which it would be difficult to obtain statements of the desired precision. (shrink)

The author presents Leszek Kołakowski from the perspective of his private acquaintanceship, lasting for about 47 years, as a witty man and a workaholic. L. Kołakowski never formed a classic “school”, but there is something all his disciples share: a thesis, key to understanding his ideas, which holds that “THERE IS MORE THAN ONE CORRECT OPINION IN THE HUMANITIES”, i.e. we will ALWAYS have opinions for and against, which goes against any dogmatism, wherever it may appear; this also bears consequences (...) in diagnosing the socio-political reality past and present.
