Rene Descartes Quotes on Mind

Descartes's Meditations gave the modern philosophy of mind its founding statement. The cogito establishes the indubitable existence of the thinking self; the real distinction between mind and body, rigorously argued in the Sixth Meditation, presents the human person as a thinking substance contingently united to an extended substance. The mind-body problem in its modern form follows directly: how can two such radically different substances causally interact, and how does the apparent unity of conscious experience emerge from their union?

Desargues puts me under obligations on account of the pains that it has pleased him to have in me, in that he shows that he is sorry that I do not wish to study more in geometry, but I have resolved to quit only abstract geometry, that is to say, the consideration of questions which serve only to exercise the mind , and this, in order to study another kind of geometry, which has for its object the explanation of the phenomena of nature... You know that all my physics is nothing else than geometry.”
