Dreaming in Descartes à la Wilson
Descartes argues that since there are no certain marks to distinguish waking experiences from dreams, we need to justify our belief that waking experiences are veridical experiences of physical objects while dreams are illusions. He resolves this problem by arguing that the absence of marks distinguishing dreams from waking experiences notwithstanding, we are justified in ascribing different cognitive values to waking experiences and dreams. For, our belief in God rules out any other explanation of the agreement of all our faculties in supporting the instinctive belief that waking experiences are caused by physical objects.
