Descartes gave the human intellect the central role in rationalism, his system therefore is a variant of intellectual rationalism. Other forms of rationalism had emerged in scholastic philosophy and the ancient philosophies of Plato and Aristotle. While Descartes had reservations with respect to all of them, he still adopted some of their elements: not even such a self-directed and critical philosopher as Descartes could have proceeded on the difficult journey towards truth without any baggage of tradition whatsoever. Those who treated this baggage as a useless burden and have attempted to pursue truth without carrying it, have only discovered things which had long been known.
