ABSTRACT
The Method of Doubt, radically and generally applied, has left Descartes, it seems, with nothing. God, the world, his own body, the past, all seem to have succumbed to it; all might be illusions. Is there anything at all that he can know to be true, that can survive the process of doubt? At this point Descartes makes the reflection which brings the Doubt for the first time to a halt, and which sets him off in the opposite direction, on the path of positive knowledge.
