cogito ergo sum T-Shirt

Cogito, ergo sum is a philosophical statement that was made in Latin by René Descartes, usually translated into English as "I think, therefore I am". The phrase originally appeared in French as je pense, donc je suis in his Discourse on the Method, so as to reach a wider audience than Latin would have allowed. Descartes's statement became a fundamental element of Western philosophy, as it purported to provide a certain foundation for knowledge in the face of radical doubt. This original Latin phrase is a great birthday and holiday gift idea for people who like awesome Latin phrases and philosophy.
