René Descartes (Latinized: Renatus Cartesius; adjectival form: "Cartesian"; March 31, 1596 – February 11, 1650) was a French philosopher, mathematician, and scientist. Dubbed the father of modern western philosophy, much of subsequent Western philosophy is a response to his writings, which are studied closely to this day. (Click here for full Wikipedia article)

The greatest minds are capable of the greatest vices as well as of the greatest virtues.
The reading of all good books is like conversation with the finest men of past centuries.
