 The broader argumentative strategy is revealed at the end of the pivotal fourth paragraph of the Third Meditation: “in order to remove even this slight reason for doubt, as soon as the opportunity arises I must examine whether there is a God, and, if there is, whether he can be a deceiver.” So, in the effort to establish the C&amp;D Rule, the meditator makes arguments to the conclusion that his creator is not an evil genius, but an all-perfect creator who would not allow him to be deceived about what he clearly and distinctly perceives.
