René Descartes (1596–1650)

"Cogito, ergo sum" (Latin: "I think, therefore I am") or Dubito, ergo cogito, ergo sum (Latin: "I doubt, therefore I think, therefore I am") is a philosophical statement used by René Descartes, which became a foundational element of Western philosophy. Descartes' original statement was in fact "Cogito ergo sum", as Descartes wrote in Latin, then the language of science in Europe. It is, however, often translated into his native French as "Je pense donc je suis.". The phrase occurs in his Discourse on Method (1637). (See Principles of Philosophy, Part 1, article 7: "Ac proinde hæc cognitio, ego cogito, ergo

Origin 

Possibly the best known of all philososophical quotations; this is from the French philosopher René Descartes in Discourse on Method, 1637, where he attempted to prove his existence as a thinking being, by thinking. 'I think, therefore I am' comes to us in English via two translations. Descartes' original statement in French was "Je pense, donc je suis". This is such a well-known line that it has spawned humourous alternatives, not least:

"I'm pink, therefore I'm spam"

"René Descartes was a drunken fart - I drink therefore I am".
