André MAUROIS (1885-1967). Autograph manuscript signed, Le dehors et le dedans; 2 pages and a quarter in-4 in his small handwriting on lined paper, with erasures and corrections. Proposals on the correspondence between soul and body. "Moral beauty succeeds in suppressing physical ugliness [...] but the reciprocal action is no less powerful, and the exterior also models the interior". Fashion is "a prodigious instrument of racial equality" and can remain original despite the uniformity of hairstyles and outfits; "fashion imprints on the face, and also on feelings, a kind of serenity. You feel in line with society"... Attached is a L.A.S. in English, London October 25, 1925, to Mrs. Watts, declining an invitation to dinner (1p. in-8 on Hotel Rubens letterhead, stamped envelope).
