The Key Ideas or basic principles circulating around the Theosophical Society since 1875—

derived from Vedanta, Buddhism, Plato, the Kabbalah, Alchemy, the ancient Mysteries and various other sources and put together in a new synthesis by HP Blavatsky, her Teachers and her followers

and treated as hypotheses, propositions and premises not binding on any member

The name given to the above by HP Blavatsky was Theosophy, but, principally, the word theosophy means divine wisdom (theosophia) and does not refer to these ideas at all but rather to a state of wisdom that is an inherent property of the Soul, or of Consciousness, when divested of all accretions in the form of thought.

The Theosophical Society is not the only place one might encounter these ideas, which particularly since the 1970s have gained a fairly wide currency in one form or another, synthesized anew by the likes of Aldous Huxley, Paul Brunton and Ken Wilber. But to give credit where it is due, the Theosophical Society was ahead of its time in its vindication of ancient traditions, and its critique of dogmatic theology and scientific materialism—a stand that is as relevant today as it was in 1875.
