CARTESIAN

From Philosopedia

CARTESIAN • Cartesian, adj. Relating to Descartes, a famous philosopher, author of the celebrated dictum, Cogito ergo sum—whereby he was pleased to suppose he demonstrated the reality of human existence. The dictum might be improved, however, thus: Cogito cogito ergo cogito sum—I think that I think, therefore I think that I am; as close an approach to certainty as any philosopher has yet made. —Ambrose Bierce The Devil’s Dictionary
