 Descartes holds an internalist account requiring that all justifying factors take the form of ideas. Various texts imply that ideas are, strictly speaking, the only objects of immediate perception or awareness. (More on the directness or immediacy of sense perception in  Section 9.1.)  Independent of assumptions about the directness of perception, Descartes’ method of doubt underwrites an assumption with similar force: for almost the entirety of the Meditations, his meditator-spokesperson – hereafter, the ‘meditator’ – adopts the methodological assumption that all his thoughts and experiences are occurring in a dream. This assumption is tantamount to requiring that justification comes in the form of ideas, rather than via direct perception of an extramental world.
