The forthcoming second volume of collected essays on The

Reprint of “L’Intuition philosophique.”  Introduction a la
metaphysique, “La Perception du Changement.”

Three articles, bearing the titles “Memoire et reconaissance,” “Perception et matiere” and “L’Idee de neant,” which appeared respectively in Revue philosophique (1896), Revue de metaphysique et de morale (1896) and Revue philosophique (1906) have been omitted from their places in the above list because they were subsequently incorporated into the larger works Matiere et Memoire and L’Evolution creatrice.
