The Matrix was a wonderful movie that graphically demonstrated the 'Brain In A Vat' thought experiment, suggested by Descartes' Evil Demon hypothesis.
If you saw a someone whitewater rafting, is she moving? or is it the kayak moving? Or is the water moving the kayak? There's three possibilities right there. The kayaker, the kayak and the water don't move at all. That's impossible. Instead... only try to realize the truth. It is not the kayak that moves, it is only your Consciousness.
