Discourse on the Method by René Descartes

Free eBook The Discourse on the Method is one of the most influential works in the history of modern philosophy, and important to the development of natural sciences In this work, Descartes tackles the problem of skepticism, which had previously been studied by Sextus Empiricus, Al-Ghazali and Michel de Montaigne. Descartes modified it to account for a truth he found to be incontrovertible. Descartes started his line of reasoning by doubting everything, so as to assess the world from a fresh perspective, clear of any preconceived notions.

The book was originally published in Leiden in the Netherlands. Later, it was translated into Latin and published in 1656 in Amsterdam. The book was intended as an introduction to three works Dioptrique, Météores and Géométrie. La Géométrie contains Descartes' initial concepts that later developed into the Cartesian coordinate system. The text was written and published in French rather than the language in which philosophical and scientific texts were most frequently written and published in at the time, namely, Latin. Most of Descartes' other works were written in Latin.
