"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 faith in immortality and able arguments in demonstration of the survival of man's spirit after death are all based on the Pythagorean system... 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... He...stoutly defended the theory of the individuality of every soul in which "personality, memory, and conscience will surely continue in the future state." He divided the astral spirit of man after its exit from the body into two distinct entities: the "aerial" and the "aethereal vehicle." During the time that a disembodied man moves in its aerial clothing, he is subject to Fate -- i.e., evil and temptation, attached to its earthly interests, and therefore is not utterly pure; it is only when he casts off this garb of the first spheres and becomes ethereal that he becomes sure of his immortality. "For what shadow can that body cast that is a pure and transparent light, such as the ethereal vehicle is? And therefore that oracle is then fulfilled, when the soul has ascended into that condition we have already described, in which alone it is out of the reach of fate and mortality.""
