Rene Descartes:

I suppose therefore that all the things I see are false; I believe that none of those things ever existed which my fallacious memory represents to me; I consider that I possess no senses; I imagine that body, figure, extension, motion and place are but fictions of my mind. What then, in short, can be esteemed as true? Perhaps nothing at all, unless that there is nothing certain.
