1 La philosophie Bergsonienne, études critiques, Paris: Marcel Rivière, 1914; second edition, with preface, Paris: Téqui, 1930. The English translation (Bergsonian Philosophy and Thomism, New York: Philosophical Library, 1955), for which the French text was revised and trimmed, may be regarded as the definitive edition of this work.

2 On the original outburst and first great formulation of this effort and this ambition, see our work The Dream of Descartes, New York: Philosophical Library, 1944. ("Rationalism dreams a great deal" could be read on the jacket of the original French edition, published in Paris by Correa in 1932.)
