PHILOSOPHY 267 



At the Faculty of Letters about a third of the courses 

 are organized exclusively with reference to the require- 

 ments for obtaining the two French degrees, the "licence" 

 and the "diplome d'etudes superieures," and for passing 

 the competitive examination, known as the " agregation," 

 which aims at selecting teachers for the lycees and 

 colleges. The rest of the courses cover an unlimited 

 range of subjects. DELACROIX, the most distinguished 

 representative of psychology of religion in France, 

 usually deals with some phase of this subject. (Vide his 

 "Essai sur le mysticisme speculatif en Allemagne au 

 XlVe siecle" and "Etudes d'histoire et de psychologic 

 du mysticisme.") BRUNSCHVICG is best known for his 

 study in Spinoza and his work on the logic of mathe- 

 matics, "Les etapes de la philosophic mathematique." 

 LALANDE always expounds some phase of the logic and 

 methods of science. (Vide his "La dissolution opposee 

 a 1'evolution dans les sciences physiques et morales.") 

 MILHAUD has made some remarkable contributions to 

 the history, criticism, and logic of science in his "Essai 

 sur les conditions et les limites de la certitude logique," 

 "Le rationnel," and his two series of studies in the 

 history of scientific thought. L. ROBIN has charge of 

 the work in ancient philosophy, and F. PICAVET of the 

 work in mediaeval philosophy. The former has pro- 

 duced two excellent studies in Plato: "Theorie platoni- 

 cienne des idees et des nombres d'apres Aristote" and 

 "La theorie platonicienne de 1'amour." The latter has 

 written two of the most accurate and impartial histories 

 of mediaeval philosophy and theology ever produced: 

 "Esquisse d'une histoire generale et comparee des 

 philosophies medie vales" and "Essais sur 1'histoire 

 generale et comparee des theologies et des philosophies 

 medievales." Of the achievements of DURKHEIM and 

 two of his associates at the Sorbonne, LEVY-BRUHL and
