Abstract

Descartes’ version of the Cosmological Argument in the Third Meditation is usually considered a failure, not because its conclusion doesn't follow from its premises, but because the truth of two of its premises is doubtful. One of these premises is that the objective reality of an idea is derived from a cause in which there is at least as much formal reality; the other, that only a being that possesses the qualities normally attributed to God could be responsible for the idea of God. Typically there are two objections made in response to the first of these premises. First, we don't understand the concepts of formal and objective reality well enough to know whether or not the premise commands our assent.
