beautiful part of his country (the Auvergne region), Bergson found time
for private study and original work. He was engaged on his Essai sur les
donnees immediates de la conscience. This essay, which, in its English
translation, bears the more definite and descriptive title, Time and
Free Will, was submitted, along with a short Latin Thesis on Aristotle,
for the degree of Docteur-es-Lettres, to which he was admitted by the
University of Paris in 1889. The work was published in the same year by
Felix Alcan, the Paris publisher, in his series La Bibliotheque de
philosophie contemporaine.

It is interesting to note that Bergson dedicated this volume to Jules
Lachelier, then ministre de l'instruction publique, who was an ardent
disciple of Ravaisson and the author of a rather important philosophical
work Du fondement de l'Induction (1871), who in his view of things
endeavoured "to substitute everywhere force for inertia, life for death,
and liberty for fatalism."[Footnote: Lachelier was born in 1832,
Ravaisson in 1813. Bergson owed much to both of these teachers of the
Ecole Normale Superieure. Cf. his memorial address on Ravaisson, who
died in 1900. (See Bibliography under 1904.)]

Bergson now settled again in Paris, and after teaching for some months
at the Municipal College, known as the College Rollin, he received an
appointment at the Lycee Henri-Quatre, where he remained for eight
years. In 1896 he published his second large work, entitled Matiere et
Memoire. This rather difficult, but brilliant, work investigates the
function of the brain, undertakes an analysis of perception and memory,
leading up to a careful consideration of the problems of the relation of
body and mind. Bergson, we know, has spent years of research in
preparation for each of his three large works. This is especially
obvious in Matiere et Memoire, where he shows a very thorough
