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"
