The Devil's Dictionary: Cartesian

CARNIVOROUS

CAT

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.
