Discourse on the Method"The greatest minds, as they are capable of the highest excellencies, are open likewise to the greatest aberrations; and those who travel very slowly may yet make far greater progress, provided they keep always to the straight road, than those who, while they run, forsake it."
Discourse on the Method of Rightly Conducting One's Reason and of Seeking Truth in the Sciences is a philosophical and autobiographical treatise published by René Descartes in 1637. It is best known as the source of the famous quotation "Je pense, donc je suis", which occurs in Part IV of the work. A similar argument without this precise wording is found in Meditations on First Philosophy (1641),
"Each problem that I solved became a rule, which served afterwards to solve other problems."
"The first precept was never to accept a thing as true until I knew it as such without a single doubt."
"The last rule was to make enumerations so complete, and reviews so comprehensive, that I should be certain of omitting nothing."
"Divide each difficulty into as many parts as is feasible and necessary to resolve it."
"Car ce nest pas assez davoir lesprit bon, mais le principal est de lappliquer bien."
"Of all things, good sense is the most fairly distributed: everyone thinks he is so well supplied with it that even those who are the hardest to satisfy in every other respect never desire more of it than they already have. (fr; en)"
