Descartes' "I think therefore I am," statement fascinates me. As does Cartesian dualism. I dont know of a more contentious, debated, or philosophized about idea. Are many recent philosophers right in totally disregarding and criticizing Descartes? And just what is consciousness? What is our mind? If I think a thought, is this thought not entirely extraneous to my body, and generally wholly individual to me? I'm especially interested in whether we all really have consciousness, can have knowledge etc; or whether it is nothing more than chemical reactions, and whether knowledge is possible for each person, or whether it is entirely socially constructed.
