So the proper order of learning will be the following. First, boys should be instructed in logical matters, because logic teaches the method of the whole of philosophy. Second, they are to be instructed in mathematics, which does not require experience and does not transcend the imagination. Third, they should be trained in the natural sciences which, though not transcending sense and imagination, nevertheless require experience. Fourth, they are to be instructed in the moral sciences, which require experience and a soul free from passion.... Fifth, they should be taught matters concerning wisdom and divine science, which go beyond the imagination and require a vigorous mind.

–St. Thomas Aquinas (Commentary on Aristotle's Ethics, VI. lect. 7)
