René Descartes

René Descartes’s famous words “Cogito, ergo sum” (“I think, therefore I am”) were the starting point from which he went on to examine the basis for knowledge. Descartes held that, by means of reason alone, certain universal, self-evident truths could be discovered, and from these the remaining content of philosophy and the sciences could be deductively derived.
