Introduction: Rene Descartes Discoveries. René Descartes initiated analytic geometry and introduced skepticism as a crucial element of the scientific method. He is considered among the greatest philosophers in history. His analytic geometry was a tremendous conceptual breakthrough, associating the previously separate fields of geometry and algebra.
Descartes showed that he could solve once-complex problems in geometry by transforming them into more straightforward issues in algebra. He defined the horizontal direction as x and the vertical direction as y.
