Kind of. Descartes said, “What am I? I am a thinking thing,” but Descartes saw the thinking thing as entirely rational, perfect intellect incapable of error as long as it does not allow itself to be hindered by will. So, for Descartes, the Self is pure intellect in tension with the will. I do not divorce the will from the Self as Descartes did. I also do not see the Self as disembodied, obviously it is embodied, but I do not reduce Self to the body, as materialists do.
