Rene Descartes was the first to develop a system for plotting ordered pairs on a grid. But he was not just famous for his geometry, or for being a mathematician, Rene was a philosopher that influenced much of modern philosophy. Rene Descartes’ philosophy (Cogito Ergo Sum – I think therefore I am) consisted of 4 rules: the first was never to accept anything as true. The second is to divide each of the difficulties into as many parts as possible. The third rule is to direct and organize your thoughts from the simplest and step by step ascend to the most complex of your knowledge. The 4th and last throughout is to make numerations.
Rene believed that you could be fooled by your senses and the only truth and reality was inside your head. Your thoughts were the only truth and nothing could exist without your thought. You were to never accept anything you see, touch, smell, hear or taste unless there is NO doubt that it is true. You start everything with yourself. Thomas Hobbes was the first to reply to his theory.
