OCCULT, something hidden, secret, or invisible. The occult sciences are magic, necromancy, and some others. Occult qualities, in philosophy, were those qualities of bo-
dy or spirit which baffled the investigation of philosophers, and for which they were unable to give any reason. Unwilling, however, to acknowledge their ignorance, they deceived themselves and the vulgar by an empty title, calling what they did not know occult.
