Descartes and his Method

The overall method of Descartes is a method of doubt. He dismisses knowledge derived from authority, senses, and reason (Watson, 2014). His demonstration is one of clarity and absolute certainty (Skirry). He is determined to bring any belief based on sensation into doubt because they might be a dream; mathematics included, because of the existence of an evil demon with supreme power of cunning about everything.
