156 - [AUTOGRAPH]. BERGSON (Henri). AUTOGRAPH LETTER SIGNED “H. Bergson” addressed to Henri DELACROIX. Vevey, July 20, 1934. Two handwritten pages on a double sheet (18 x 11 cm), with an autographed, stamped, and postmarked envelope addressed to “Mr. Henri Delacroix, Dean of the Faculty of Letters,” forwarded to the Hôtel des Bains in Aix-les-Bains. Horizontal fold. A BEAUTIFUL PHILOSOPHICAL LETTER ON MEMORY AND THE NATURE OF INTELLIGENCE. Bergson thanks his correspondent for sending him *Les Grandes Formes de la vie mentale*, a work published by Félix Alcan in 1934. He explains that his move to the countryside, “which is always rather difficult for me,” delayed his reading of it, and then expresses his admiration: “The book is of the utmost interest. On each of the subjects you study, it places us at a perspective that is uniquely your own and yet remains remarkably comprehensive, with nothing of importance being excluded. ” He particularly highlights two topics central to his own research: “I was especially struck by your chapter on memory, and also by your conception (which could give rise to such interesting discussions) of the nature of intelligence.” He concludes with his compliments and a friendly closing. The recipient, Henri DELACROIX (1873–1937), a philosopher and psychologist, was then dean of the Faculty of Letters in Paris. This letter attests to Bergson’s attention to his colleague’s work, combining praise with an invitation to philosophical discussion.
