His travels all over the world incited him to recount his experiences and adventures, the most famous works being "L'Usage du monde" and "Le Poisson-scorpion". His work is marked by a commitment to report what he sees and feels, shorn of any pretence of omniscience, leading often to an intimacy bordering on the mystical. His journey from Geneva to Japan was in many ways prescient of the great eastward wave of hippies that occurred in the sixties and seventies - slow, meandering progress in a small, iconic car, carefully guarded idiosyncrasy, a rite of passage. Yet, it differs in that the travelogues this journey inspired contain deep reflections on man's intimate nature, written in a style very much aware and appreciative of the traditions and possibilities of the language he uses. (He wrote mainly in French, though he does mention writing a series of travel articles in English for a local journal during his stay in Ceylon.)
