In cogitation the thought or attention flits aimlessly about the subject. In meditation it circles round it, that is, it views it systematically, from all sides, gaining perspective. In contemplation it radiates from a centre, that is, as light from the sun it reaches out in an infinite number of ways to things that are related to or dependent on it.
—Ezra Pound, 1909, recalling in his own words ideas from Richard of St. Victor
