"Although neither an alchemist, magician, nor astrologer, but simply a great philosopher, Henry More, of Cambridge University — a man universally esteemed, may be named as a shrewd logician, scientist, and metaphysician. His belief in witchcraft was firm throughout his life. His faith in immortality and able arguments in demonstration of the survival of man's spirit after death are all based on the Pythagorean system, adopted by Cardan, Van Helmont, and other mystics. The infinite and uncreated spirit that we usually call God, a substance of the highest virtue and excellency, produced everything else by emanative causality. God thus is the primary substance, the rest, the secondary; if the former created matter with a power of moving itself, he, the primary substance, is still the cause of that motion as well as of the matter, and yet we rightly say that it is matter which moves itself. "We may define this kind of spirit we speak of to be a substance indiscernible, that can move itself, that can penetrate, contract, and dilate itself, and can also penetrate, move, and alter matter,"("Antidote," lib. i., cap. 4.) which is the third emanation."
