QUOTE : the strangest phenomenon of all. While the sciences of old operated on practical theories built around things that could be seen and touched and felt, the sorcery of our own time operates on an entirely different principle. Its power is potent only when it is believed, for it is power over the mind which can neither be touched nor seen through human senses. If the mind does not truly find some basis for belief in its existence, then it can have no real effect. The Warlock Lord realizes this, and the mind’s fear of and belief in the unknown—the worlds, the creatures, all the occurrences that cannot be understood by men’s limited senses—offer him more than enough basis upon which to practice the mystic arts.
