I suppose, then, that all the things that I see are false; I persuade myself that nothing has ever existed of all that my fallacious memory represents to me. I consider that I possess no senses; I imagine that body, figure,extension, movement and place are but the fictions of my mind. What, then, can be esteemed as true? Perhaps nothing at all, unless that there is nothing in the world that is certain.
Rene Descartes, Meditations on First Philosophy
Common sense is the most fairly distributed thing in the world, for each one thinks he is so well-endowed with it that even those who are hardest to satisfy in all other matters are not in the habit of desiring more of it than they already have.
Descartes
Perfect numbers like perfect men are very rare.
Rene Descartes
You ever have that feeling where you’re not sure if you’re awake or still dreaming?
The Matrix
If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.
Rene Descartes
Bernard Williams on Descartes
Doubt is the origin of wisdom.
Rene Descartes, Meditations on First Philosophy
