Descartes is, of course, perhaps most famous for the ideas he laid down in his Discourse on the Method and Principles of Philosophy. It is here that he decides that the only thing we can know without any doubt is that we are thinking beings.

That our bodies are merely the vessels in which we live. I want to find a way to convince you to understand that we think with our bodies, and feel with our minds.
That we feel, and therefore we are.
