Discours de la méthode is the original French text of René Descartes’s Discourse on the Method, published in 1637. In it Descartes sets out his method of doubt and reasoning and arrives at his celebrated principle “je pense, donc je suis” — I think, therefore I am.
Please note that this edition is in French. A founding work of modern philosophy and science, the Discourse helped establish the rationalist tradition and was deliberately written in the vernacular to reach beyond the learned. This free EPUB edition presents the complete French text for readers of French and students of early modern philosophy.
