Rene Descartes' overall objective in publichising "Discourse of Method" is to developing a new system of knowledge that is free of prior prejudices for establishing the truth of In Part 4 of the book he explains the philosophical basing (the mediatations) for establishing the new system. These mediatations were based on the epistomological theory of rationalism: that is if someone truly knows something then they could not possibly be mistaken.

He has difficulty embracing the diverse, and sometimes hypocrtical, ideas that he encountered in his studies. He thought all of his confusions and indeterminate ideas were caused by the senses.

In fact, no single criterion can be established to distinguish between the conscious and a sleeplike state. Consequently, this very instance may be a dream, all beliefs based upon the sensory organs are dubitable.Besides, many of us, at one point in our lives, have wondered this very philosophical ques...
