COGITO, ERGO SUM


COGITO, ERGO SUM
   "I think, therefore I am." Descartes' principle of certainty, and on which, as on a stable basis, he reared his whole philosophy. See DESCARTES, RENÉ. "Alas, poor cogitator," Carlyle exclaims, "this takes us but a little way. Sure enough, I am; and lately was not; but Whence? How? Whereto?"
