Context

“But who desires to see him—him, who is yet the most sober and moderate of the whole gang of philosophers, lay about him with greater boldness, and relate his miracles upon this subject, I refer him to his treatise of the Moon, and of the Demon of Socrates, where he may, as evidently as in any other place whatever, satisfy himself that the mysteries of philosophy have many strange things in common with those of poetry; human understanding losing itself in attempting to sound and search all things to the bottom; even as we, tired and worn out with a long course of life, return to infancy and dotage. See here the fine and certain instructions which we extract from human knowledge concerning the soul. Neither is there less temerity in what they teach us touching our corporal parts.” source
