Document Summary
Rene descartes :passions of the soul: he is the author of discourse on method (1637), meditations on first. Philosophy (1641), and principles of philosophy (1644): descartes is best-known for the cogito argument of the meditations, in which he claims: cogito ergo sum, or, i think therefore i am. This phrase does not appear in the meditations, but the french equivalent appears in his discourse on method: challenges his presuppositions , thinks that you cant appeal to authority in order to challeges presuppostitions. The mediations: descartes maintains that he will doubt everything until he discovers either a certain, indubitable principle or the principle that nothing it certain, he argues that if he can be persuaded or deceived then he must exist. I have persuaded myself that there is absolutely nothing in the world but doubtless i did exist, if i persuaded myself of something.
