 The possibilities that Descartes mentions early in the Meditations are not a part of his ontology. When he talks about these, he is not interested in truth but, rather, in helping his reader to move through and past  confusion.[7]  Unless we are going to saddle Descartes with the view that it really is possible that our minds are radically defective and that nonetheless we ought to go on reasoning anyway, we should conclude that Descartes holds that the possibilities of the First Meditation were never created and that hence they are nothing at all.
