Hermeticism’s three-fold root of knowledge: Alchemy, Astrology and Theurgy
The hermetic writings contain a set of principles of knowledge known as”The three parts of the wisdom of the whole universe”:
1. Alchemy — An investigation into the spiritual essence of matter through an application of the mysteries of birth, death, and resurrection. In this sense, the metaphysical backdrop of the hermetic mysteries should be understood as a kind of panpsychism or vitalism.
2. Astrology — Hermes states that Zoroaster taught astrology to humanity. The movements of bodies in space symbolically illustrate spiritual properties that exist in God.
3. Theurgy - Giovanni Pico della Mirandola’s Apology distinguishes between Goëtia (black magic) associated with divination of evil spirits and Theurgy, which focuses on reliance upon other, more benevolent, divine spirits.
