The document discusses René Descartes and his contributions to philosophy and science during the Scientific Revolution. Descartes established modern philosophy and analytic geometry. He wrote Discourse on Method where he argued that nothing should be accepted on faith and everything must be doubted until proven through reason. His most famous conclusion was "I think, therefore I am", establishing that he knows he exists through his ability to think and doubt.
