Bernardin de SAINT-PIERRE (1737-1814). Autograph manuscript, De la nature; 1 oblong page in-4 with erasures and corrections. Draft for his Studies of Nature, first ideas in the form of a dialogue with Jean-Jacques ROUSSEAU: "I said one day to Jean-Jacques, there are five hundred ways of seeing nature, yes he answered me without the real one. Nature resembles a vast mountain, of which one side I also believe that the organs and the reason given to each man to observe it are not less vain"... Etc.
