Hiebert The clearest and most comprehensive statement of Mach's mature scientific epistemology is given in the compilation of twenty-five essays that he published in 1905 under the title: Erkenntnis und Irrtum. Skizzen zur Psychologie der Forschung. These essays were drawn, as Mach tells us, from his winter semester lecture course delivered in 1895/6 in Vienna and entitled Psychologie und Logik der Forschung. Translated, at least in part, into French (1908), Russian (1909) and Turkish (1935), it seems puzzling, to say the least, to see that the crowning work of Mach's philosophical deliberations - Knowledge and Error - should have waited seventy years to appear in English.! This delay is all the more surprising in view of the attention given to Mach's works by English scholars since at least the 1890's. The incentive for Mach's wide and sustained readership in the English-speaking world is, of course, closely related to the efforts of Paul Carus, editor of the Open Court Publ. Co. of LaSalle, Illinois. Mach's Die Principien der physikalischen Optik was dedicated to Carus posthumously in 1921. By 1926 all of Mach's important monographs had been brought out in English by Open Court with the exception of Wiirmelehre and Erkenntnis und Irrtum. The first American edition of Mach's Mechanics, for example, was published in 1890, and the sixth, with a new introduction, in 1960. With the publication of the present volume, and the Wiirmelehre (now in process of being translated), all of Mach's major treatises, finally, will be available in English. It may not be inappropriate to mention that this would have pleased Mach enormously. He was an outspoken Anglophile and attached himself to the empirical tradition of Berkeley, Hume and Mill. He cham pioned the approach to physics of Faraday and Maxwell. Among the staunchest of allies for his epistemological views, Mach included econo mist-logician W. S. Jevons, the mathematician-physicist-philosophers W. K. Clifford, P. E. B. Jourdain, and Karl Pearson. To Pearson he dedicated the third edition of Die Analyse der Empfindungen (1902). On the Continent Mach's favorite philosopher-scientists were Kirchhoff, Helmholtz, Hertz, Duhem and Poincare. XII INTRODUCTION Erkenntnis und Irrtum. Skizzen zur Psychologie der Forschung. Von E. MACH Emer. Professor an der Unlversltlt Wlen. LEIPZIG Verlag von Johann Ambrosius Barth 1905. INTRODUCTION XIII On a number of occasions Mach expressed the sentiment, especially in his correspondence, that America was the land of intellectual freedom and opportunity, the coming frontier for a new radical empiricism that would help to wash metaphysics out of philosophy. In 1901 he sponsored the German edition of Concepts and Theories of Modern Physics (1881) by J. B. Stallo, Cincinnati lawyer and philosopher.2 Mach warmly endorsed Stallo's book because his scientific aims so closely approximated his own, and because Stallo rejected the latent metaphysical elements and concealed ontological assumptions of the mechanical-atomistic inter pretation of the world. The second edition of Wiirmelehre was dedicated to Stallo in 1900. The fourth edition of Populiir-wissenschaftliche Vorlesungen (1910), containing seven new essays, was dedicated to Harvard Professor of physiology, philosophY, and psychology, William James. Mach had a strong intellectual affinity for James' pragmatism because, like himself, he recognized that James had come to radically empirical views from science. Both men took pure pre-conceptualized experience, from which the mental and physical predicates of experience are composed, to be neutral rather than real, unreal, objective or subjective. Mach was so taken with James that he thanked him for giving him his first understanding of Hegel. James was so impressed with his visit with Mach in Prague in 1882 that he wrote his wife: As for Prague, veni, vidi, vici. I went there with much trepidation to do my social scientific duty .... I heard Hering give a very poor physiology lecture, and Mach a beautiful physical one ...• Mach came to my hotel and I spent four hours walking and supping with him at his club, an unforgettable conversation. I don't think anyone ever gave me so strong an impression of pure intellectual genius. He apparently has read everything and thought about everything, and has an absolute simplicity of manner and winningness of smile ... 8 In a letter to Carl Stumpf at the same time, James wrote: [In Berlin] Helmholtz ... gave me the very worst lecture I ever heard in my life except one (that one was by our most distinguished American mathematician). The lecture I heard in Prague from Mach was on the same elementary subject as Helmholtz's, and one of the most artistic lectures I ever heard .... Oberhaupr I must say that the hospi tality of Prague towards wandering philosophers much surpasses that of Berlin and Leipzig.4 Stumpf thought Mach's "positivistic theory of knowledge ... impossible and unfruitful".5 XIV INTRODUCTION BibliotheqLle de PiJilosopiJie scientifique ERNST MACH "nU.·E~:::''':t:r. .\ L'LJNI\,KIISITi: Ot: Vn;NNE LA Connaissance et l'Erreur 'l'RADUl'f StiR LA DERNIERE f.:DI'l'ION ALLEUANDE PAR ]e D" MARCEL DUFOUR l'non;sSEun ACnEGK ~ I..\ F.\r.lU'; II ..

INTRODUCTION xv The circumstances that led to Mach's Knowledge and Error are signifi cant for an understanding of the dual historical and philosophical focus and implications of the work. Its completion, as a synthesis of epistemolo gical and methodological inquiries, was coupled with Mach's decision to begin a new chapter in his professional career when the opportunity presented itself. In 1895 Mach was invited to accept the third chair in philosophy at the University of Vienna.
