Discours de la méthode
By an almost universal agreement among philosophers and historians, Rene' Descartes is considered the originator of modern philosophy, or at least the first important philosopher of our times. If we add to this the common belief that philosophy points the way for developments in all other fields, it will be evident that to Descartes is ascribed an importance comparable to that of the beginnings of intellectual culture in Greece or of the origin and spread of Christianity in the Mediterranean regions, and surpassing all other events in history. The study of Descartes can start in no more appropriate way than by inquiring into his reputation, and deciding in what sense and to what extent it is justified. Discourse on Method was originally published in 1637.
