Rene Descartes
René Descartes did not begin by looking for certainty; he began by discovering how easily the mind can be fooled, and then asked what, if anything, survives when every borrowed belief is taken away.

Timeline
Birth of René Descartes
**1596-03-31** — René Descartes was born in La Haye en Touraine, in central France. His later philosophy would be shaped by the intellectual tensions of an age that demanded both faith and method, tradition and innovation.
Begins Jesuit education at La Flèche
**1606** — Descartes entered the Collège Royal Henry-Le-Grand at La Flèche, where he received a rigorous Jesuit education. The scholastic curriculum gave him command of the tradition he would later rework from the inside.
Meets Isaac Beeckman
**1618** — In the Dutch Republic, Descartes met Isaac Beeckman, who encouraged his mathematical and mechanical interests. The encounter helped direct him toward a new kind of natural philosophy built on quantitative reasoning.
The intellectual breakthrough traditionally linked to his dreams
**1619** — Descartes later described a powerful sequence of dreams and reflections that convinced him of a unified scientific method. The episode became part of the mythology of Cartesian certainty, though scholars treat it cautiously as biographical evidence.
Publication of Discourse on Method
**1637** — Descartes published the Discourse on Method, along with essays on optics, geometry, and meteorology. The work presented his four rules of method and showcased the ideal of clear, orderly reasoning.
Publication of Geometry
**1637** — The Geometry annexed to the Discourse demonstrated a powerful algebraic treatment of geometric problems. It became one of the key texts in the mathematization of natural philosophy.
Publication of Meditations on First Philosophy
**1641** — The Meditations set out methodic doubt, the Cogito, proofs of God, and the distinction between mind and body. It became the central statement of Cartesian epistemology and metaphysics.
Objections and Replies appear
**1641** — A collection of objections from leading critics, including Arnauld and Hobbes, was published with Descartes’s replies. The exchange exposed the deepest vulnerabilities in the new system while refining its claims.
Publication of The Passions of the Soul
**1649** — In this late work Descartes offered a psychology of emotion, bodily movement, and the union of mind and body. It shows how far his project extended beyond abstract doubt into lived human experience.
Moves to Sweden
**1649** — Descartes went to Stockholm at the invitation of Queen Christina. The move placed him in a new courtly and climatic environment, far from the Dutch Republic where much of his mature work had been formed.
Death of Descartes
**1650-02-11** — Descartes died in Stockholm in 1650. His death did not end Cartesianism; it marked the beginning of its transformation into one of the defining projects of modern philosophy.
Cartesianism becomes a European controversy
**1680** — By the later seventeenth century, Descartes’s ideas had spread through philosophy, science, and theology, provoking both development and resistance. His work became the background against which rationalists, empiricists, and critics defined themselves.
