Metodin esitys Finnish edition

Philosopher and mathematician René Descartes is regarded as the father of modern philosophy for defining a starting point for existence, "I think; therefore I am." René Descartes was born on March 31, 1596, in La Haye, France. He was extensively educated, first at a Jesuit college at age 8, then earning a law degree at 22, but an influential teacher set him on a course to apply mathematics and logic to understanding the natural world. This approach incorporated the contemplation of the nature of existence and of knowledge itself, hence his most famous observation, "I think; therefore I am."
