[1] Also called Analogeticists. As explained by Prof. Alex. Wilder, F.T.S., in his “Eclectic Philosophy,” they were called so because of their practice of interpreting all sacred legends and narratives, myths and mysteries, by a rule or principle of analogy and correspondence: so that events which were related as having occurred in the external world were regarded as expressing operations and experiences of the human soul. They were also denominated Neo-Platonists. Though Theosophy, or the Eclectic Theosophical system, is generally attributed to the third century, yet, if Diogenes Laertius is to be credited, its origin is much earlier, as he attributed the system to an Egyptian priest, Pot-Amun, who lived in the early days of the Ptolemaic dynasty. The same author tells us that the name is Coptic, and signifies one consecrated to Amun, the God of Wisdom. Theosophy is the equivalent of Brahma-Vidya, divine knowledge. [2] Eclectic Theosophy was divided under three heads: (1) Belief in one absolute, incomprehensible and supreme Deity, or infinite essence, which is the root of all nature, and of all that is, visible and invisible. (2) Belief in man’s eternal immortal nature, because, being a radiation of the Universal Soul, it is of an identical essence with it. (3) _Theurgy_, or “divine work,” or _producing a work of gods_; from _theoi_, “gods,” and _ergein_, “to work.” The term is very old, but, as it belongs to the vocabulary of the MYSTERIES, was not in popular use. It was a mystic belief—practically proven by initiated adepts and priests—that, by making oneself as pure as the incorporeal beings—_i.e._, by returning to one’s pristine purity of nature—man could move the gods to impart to him Divine mysteries, and even cause them to become occasionally visible, either subjectively or objectively. It was the transcendental aspect of what is now called Spiritualism; but having been abused and misconceived by the populace, it had come to be regarded by some as necromancy, and was generally forbidden. A travestied practice of the theurgy of Iamblichus lingers still in the ceremonial magic of some modern Kabalists. Modern Theosophy avoids and rejects both these kinds of magic and “necromancy” as being very dangerous. Real _divine_ theurgy requires an almost superhuman purity and holiness of life; otherwise it degenerates into mediumship or black magic. The immediate disciples of Ammonius Saccas, who was called _Theodidaktos_, “god-taught”—such as Plotinus and his follower Porphyry—rejected theurgy at first, but were finally reconciled to it through Iamblichus, who wrote a work to that effect entitled “De Mysteriis,” under the name of his own master, a famous Egyptian priest called Abammon. Ammonius Saccas was the son of Christian parents, and, having been repelled by dogmatic spiritualistic Christianity from his childhood, became a Neo-Platonist, and like J. Boehme and other great seers and mystics, is said to
