PHILOSOPHICAL PEEIODICALS. 58$ stitutes more convenient means of expression and action for less con-' venient means. Thus also shall we get an altogether general idea of science, on the principles of positivism.] G-L. Duprat. ' Centre 1'in- tellectualisme en psychologic.' [A very brief sketch of the evolution of mind, with the view of showing the possibility of what the author calls a psychology liberated from the intellectualist prejudice, i.e. a scientific psychology whose principles of explanation would be derived from the consideration of genial tendencies and conservative habits.] Revue Critique.

Le Dantec. ' Les objections au monisme.' [A defence of monism as denned by the following formula : " Nothing happens in man without the modification of something that can be measured ". It is impossible for a monist who accepts this formula to conceive consciousness otherwise than as a mere epi-phenomenon. This latter theory, whose vindication seems to be the veritable aim of the author, will be studied in a second article.] Roerich. ' L'Attention spontanee dans la vie ordinaire et ses applica- tions pratiques.' [Spontaneous attention is either primitive or apper- ceptive. These forms in their relation to ordinary life are both studied by the writer, who states and illustrates, in a very interesting way, their scientific laws and the practical rules to be derived from them.] A. Chide. 'La Logique avant les logiciens. ' [Rationalistic logic or the philosophy of concepts has crushed down, by the genius of Socrates and the Platonists, the other logics or dialectics that could possibly have organised the ideation and life of our (so-called) Aryan race. But was this logic necessary ? The only method to find an answer is to seek whether the general original structure of our Indo-European languages- is in conformity with the rationalistic logic or not. A survey of the diverse linguistic theories of Bopp, Brugmann, Regnaud, etc., leads M. Chide to an identical conclusion, viz., that the primitive thought was not at all directed towards rationalism. The primordial conception is aware of all relations, all modalities : .subsumption is unknown to it. It is to a subsequent deviation from nature and a kind of aberration that the emergence of the characteristics of rationalised mind is to be ascribed.] Edme Tassy. ' Le Syinpathique et 1'ideation.'
