L'Idéalism de Lachelier (review)

112 HISTORY OF PHILOSOPHY Gallie's Peirce and Pragmatism (1952). She believes that the translation of Peirce's theory of the categories into the conceptual framework of British empiricism and naturalism misrepresents Peirce's cosmology which had very peculiar traits--traits which the author associates with the Platonic tradition. She shows in detail how Peirce tried at first (1868) to relate his three categories to the Scotist, Scholastic, concepts of "essence" and "substance," and how, in his various phaneroscopic experiments, he gradually repudiated the Scholastic languages and by 1902 was ready to interpret his three categories as an adequate ontology. What led Peirce in this direction was his critique of perceptual judgment. He realized that subject and object are in dynamical, social, and historical relation to each other. A logical object is, therefore, also a "dynamic object" or objective. This insight led him at first to regard his doctrine of signs and their interpretation as a humanist or idealist doctrine, for the idealists had also recognized objects as objectives. Nynfa Bosco is quick to appreciate that this interpretation of acts of knowing is closely related to Gentile's idealism. But gradually a more ontological and Platonic interpretation emerges in Peirce, until in the end "thirdness" is a modernist version of the reality of universals. She believes Peirce's greatest achievement was his exposition of "thirdness" as an ontological mediation between modern idealism and Scholastic realism and his theory of evolution as a continuity of physical and mental events. The volume closes with chapters on Peirce's mathematics, ethics, esthetics, philosophy of religion, theology, and psychology. Those chapters are not mere expositions but critical evaluations. To review Nynfa Bosco's criticisms would take us far beyond the limits of an historical review. Suffice it to say that her criticisms are acute as well as sympathetic, and that they reflect well some of the differences between Italian and American tendencies in philosophical analysis. For several reasons, in short, this work deserves to be known internationally. It probably deserves also to be translated, though a translator would find it difficult to maintain the liveliness of her Italian style, which makes reading the book a pleasure as well as an instruction. HERBERT W. SCHNEIDER Claremont, Calilornia L'Iddalism de Lachelier. By Gaston Mauchaussat. (Paris: Presses Universitaires , Biblioth6que de Philosophie Contemporaine [N.F. 18], 1961. Pp. 224.) This is really an intellectual biography of Jules Lachelier (1832-1918); it traces the development of his idealism from 1866 to 1913 and of his moral BOOK REVIEWS I13 philosophy from 1868 to 1918. According to Lachelier himself, there was a significant change in his thinking when, in 1875, he ceased being a teacher, but M. Mauchaussat finds significant elements of the later development even in his earliest works. In general, according to this account, there was a continuous development from subjective to Platonic idealism and from empirical ethics to his axiological theodicy. The documentation and exposition are detailed and precise. The figure of Lachelier emerges as an important historical link between the romantic idealism of the early nineteenth century and the objective value theory or "philosophie de l'esprit" of the twentieth. Though Lachelier himself seems to have forgotten or discounted the early influence on him of Maine de Biran, the author of this biography finds good evidence that his early "Berkeleyan" idealism was derived largely from Maine de Biran and led him to make a careful study of the empirical psychology of thinking and of the importance of habit. D~s 1858, lisant l'introduction du M6moire de Maine de Biran sur l'influence de I'habitude, il en tire cette cons6quence que les esprits ne peuvent d6velopper leurs diverses puissances que par leur union avec le corps et qu'en somme l'homme pense parce qu'il parle (p. 13). It is evident that Lachelier's primary concern was to find in an empirical idealism a mediator between dogmatic naturalism and the equally dogmatic "spiritualism" which the school of Victor Cousin had established in academic circles. It was Ravaisson who guided him in this search. His course at the Ecole Normale Superieur, to which he was called in 1864, gave him an opportunity to work...
