Descartes:00008

The famous words cogito ergo sum (which render themselves so elegantly in English as “I think, therefore I am”) never appear in the original version of the Meditations, only in a later and indeed rather casual translation. The actual words used are better translated as: “let the Demon deceive me as much as he may, he will never bring it about that I am nothing so long as I think I am something. So, after considering everything very thoroughly, I must conclude that this proposition, I am, I exist, is necessarily true, every time that I say it, or conceive it in my mind.”
