Dutch titles have been omitted in both parts of the Bibliography unless they are referred to in the translation. The book by Halmos replaces a Dutch introduction to set theory. I am greatly indebted to Miss Veronique Kroon for expert assistance in improving the English of the translation. The remaining imperfections are probably the cases where I did not follow her advice. v CONTENTS TRANSLA TOR'S NOTE V FOREWORD IX PREFACE XI I. SCIENCE AS A CULTURAL FACTOR (1948) 1 11.

He had already prepared the greater part ofthe volume for the press and had also decided on the title Science a Road 10 Wisdom. His original selection was somewhat more comprehensive, which is still partly reflected in the Preface. Knowing how much he wished to see this collection published, I respectfully and lovingly fulfil his request, thanking Else M. Barth and J. J. A. Mooij for their extensive and expert care in putting the final touches to the volume. ADDITION TO THE TRANSLATION Finally, I wish to thank Peter G. E. Wesly for his willingness to undertake the translation of the book into English. c. P. c. BETH-PASTOOR IX PREFACE In this republication of a number of philosophical studies I have refrained from including articles of a specialized nature on symbolic logic and the methodology of the exact sciences. There was no cause to include my contributions towards the didactics of mathematics and physics, nor did I consider it appropriate to reprint pieces of a predominantly polemical nature. I decided, however, that a very modest selection from my purely historical work would not be out of place. Of the four stages in my intellectual development as set forth in Essay XI, the first stage (up to 1935) is not represented, the second (1935-42) is represented by Essay VI, the third (1942-50) by Essays I, 111 and IV. The remaining essays (11, V and VII-XII) are characteristic of the position I have taken up since about 1950. Thus the earlier periods are represented comparatively scantily, the explanation being that I only started publishing towards the end ofthe first stage and that most ofthese publications are not suitable for thiscollection, for thereasons stated above. Two essays (IV and V) originally appeared in English, the others in Dutch. Ofthe essay which is now VIII, the middle part has been dropped. I have made corrections in most of the papers, as weIl as some small modifications ensuring the necessary uniformity of style, spelling, notation and, as much as possible, of terminology. Moreover, I have supplemented the bibliographical references and combined them into a single bibliography. Although I should hardly wish to answer for Bergson's weIl-known dictum Un philosophe digne de ce nom n'a jamais dit qu'une seule chose (nobody deserving the name of philosopher has ever said more than one single thing), it still reassured me when I found that in some cases the same line of thought, with slight variations, returned in several articles. If all the alternative versions but one had been dropped, stylistically unacceptable gaps would have appeared. Indeed, a number of alternative readings may facilitate an accurate comprehension, while the recurrence of the same line of thought in several different contexts gives an im- XI SCIENCE A ROAD TO WISDOM pression of its fruitfulness. Taking all this into account, I have decided on the following policy. Of each set of variants, one has been rendered as completely as possible; the remaining variants have been shortened as much as the context allows and have been provided with a reference to the complete version. Tbe material has been arranged systematically, not chronologically, for the aim of this volume is, above all, to give the reader a coherent and more or less complete survey of my ideas and my work in the field of general philosophy, so that, I hope, there will be less misunderstanding and uncertainty ab out it in the future. It is probably clear now that I have not aimed at being exhaustive. For further elaboration and more detailed explanations I refer to my monographs. This book is intended for all who are interested in philosophy. A reasonable amount of general knowledge is required, and the reader should not object to some intellectuallabour: a book such as this is not meant as light entertainment. I should be particularly gratified if it were to be read by the younger generation. It cannot be denied that many young people, especially those destined by their talents and education to occupy leading positions in our society in the near future, are much given to irrationalistic trends. This is quite understandable; it is explained by the decline of traditional rationalism and by the strongly increased attention for and knowledge ofthe irrational forces in man. Moreover, ours is a time of unprecedented and yet ever increasing rationalization of all forms of human life, and seeking refuge in irrationality is no doubt partly a natural reaction to these conditions of our time. One does not, however, have to be an extreme rationalist to realize that unbridled irrationalism can hardly be conducive to the adjustment of the intellect to modern man's present and apparently self-chosen environment, or to be concerned about the eventual consequences of the lack of adjustment. If we wish to enjoy the benefits that our rational civilization has to offe r without understanding the foundations on which it rests, we shall not be able to make a critical evaluation of undesirable forms of rationalization or to recognize dangerous developments before it is too late. We would thus be powerless against the collectivism that could proceed from undesirable forms of rationalism combined with certain manifestations of the irrational drives in man. XII PREFACE In order to adjust the intellect to contemporary conditions of life, to make a critical evaluation of the different forms of rationalization and to control the irrational forces in man, we shall require scientific discern ment and a capacity for rational discussion. Certainly, these requirements, while enabling us to act efficiently, do not guarantee sensible behaviour; nevertheless, the wisdom we are seeking should be closely connected with scientific insight. I do not claim to have even so much as drawn the outlines of the modern rationalism wh ich in my opinion our time stands in need of, though I believe to have done some preliminary work for the development of such a rationalism. In the first place, I have pointed out some weak spots in the foundations of traditional systematic philosophy, which is predominantly rationalistic. These foundations date back mainly to Aristotle; my criticism does not, however, detract from my admiration for this thinker whose work has determined the structure and develop ment of western philosophy for over 2000 years. In the second place I believe to have given modern logic a form which renders it a suitable foundation for the development of a new epistemology and a new ontology. Moreover, the conditions have thus partly been created for the development of a new ethics which does justice to modern psychological insight and at the same time avoids the extremism of present-day irrationalism.
