Descartes was wrong when he said "I think, therefore I am," concluding that above all else only one's own conscious experience could be definitely affirmed. What I think he should have said was, "I think, therefore I am thinking." In my view, "I," "self," "ego," are not what is doing the thinking---though that is certainly the illusion---but themselves just other thoughts part of the stream of consciousness.
