Descartes' Argument for the Claim that his Essence is to Think

Two previous attempts to discern the argument Descartes intended to establish the claim that his essence is to think have failed to meet with success. I examine those arguments and offer an interpretation of my own that follows one of Descartes' strategies in the cogito passages. The suggested interpretation involves discarding every candidate that falls victim to hyperbolic doubt. However, while my strategy may have been intended by Descartes, it does not successfully yield his conclusion.
