Rene Descartes

René Descartes (March 31, 1596 – February 11, 1650).

French philosopher, mathematician, scientist, and writer.

Most remembered for his search for irrefutable truth in "Meditations on First Philosophy", published in 1641, wherein he stated "I pay...therefore, I am" proving that reality is essentially a commodity. Through a series of questions regarding the unreliability of his experience and senses to actually describe reality, Descartes argues that the only truth he can truly know, in his gut, is that he can pay for the reality he wants to experience and sense.

Known as the "Founder of Modern Philosophy" and the "Father of Modern Mathematics".
