Cogito, Agito, Dualism

The relation between Agito--I Act--and Cogito emerges from an examination of an erroneous interpretation of the latter.  Kant represents it as an impersonal function, but Certainty, as opposed to Necessity, is a personal condition, so Descartes' attribution of Certainty to Cogito indicates that it is not impersonal.  Instead, 'X is certain that P', like 'X believes that P', and 'X doubts P', are what Russell calls Propositional Functions.  Accordingly, Doubting, Believing, and Thinking, in general, are empty without some Proposition as an object.  Thus, 'Doubting that one Doubts' must be elliptical for 'Doubting that one Doubts some P', so that Descartes' inference from 'I cannot doubt that I am doubting' to 'I am certain that I am thinking' can only be elliptical for an inference to 'I am certain that I am thinking some P'.  In other words, his derivation of an ontologically detached Cogito from this Doubting exercise is invalid, i. e. I Think essentially has some other Proposition as an object.  Now, as the Pragmatists argue, to believe that P means to be willing to act on P, and, correspondingly, for doubting that P and unwillingness to act on it.  For example, to believe that it is raining out means to be willing to carry an umbrella.  Thus, Cogito, in general, guides Agito, just as the arrow of a Vector signifies the direction of motion away from an origin.  Furthermore, Spinoza argues that Cogito is essentially volitional, i. e. that the fundamental Propositional Attitude is Intention, in which case the arrow of a Vector signifies, specifically, the whither of Agito, i. e. a purpose.  In either case, the Vector illustrates that Descartes' Mind-Body dualism, and its subsequent mediation by a deity or the pineal gland, is already the product of a hypothetical fragmenting of an original continuum, i. e. the separation of the point of origin of a Vector, from the directed line that emerges from it.  Thus, Descartes' Geometry illustrates what Doubting the thesis confirms--that his Mind-Body Dualism is derived not Methodically, but from his Theological commitments, i. e. even the certainty that 'God exists' does not prove the separation of Mind and Body.
