The word "occult" means that which is hidden. Occultism, consequently, is the science of hidden forces, and the art of subjecting such forces to human control. Here we will consider the data upon which occultism rests. The word carries with it an air of mystery, it is true; but all forces are mysterious to those who have not studied them; and what is mysterious to the ignorant is obvious to the learned. Yet in all nature, nothing can come permanently under this ban; for all mysteries may be solved. Thus the simplest conveniences of modern civilization are mysterious to the untutored savage. He is wont to attribute their power to some supernatural agency. But there is nothing supernatural—nothing, that is, not governed by natural laws.
