Theosophy, literally "god-wisdom" (Greek: θεοσοφία theosophia), designates several bodies of ideas. The 6th century neo-platonist Pseudo-Dionysius seems to have been the first philosopher the term applied to. There was a group of Renaissance philosophers: Cornelius Agrippa, Paracelsus, Robert Fludd, and, especially, Jacob Boehme; the Enlightenment theologian Emanuel Swedenborg was influenced by these. And finally, the word was revived in the nineteenth century by Helena Petrovna Blavatsky to designate her religious philosophy which holds that all religions are attempts by humanity to approach the absolute, and that each religion therefore has a portion of the truth. Together with Henry Steel Olcott, William Quan Judge, and others, Blavatsky founded the Theosophical Society in 1875. This society has since split into a number of organizations, some of which no longer use the term "theosophy".
A formal definition from the Concise Oxford Dictionary describes Theosophy as "any of various philosophies professing to achieve a knowledge of God by spiritual ecstasy, direct intuition, or special individual revelation; esp. a modern movement following Hindu and Buddhist teachings, and seeking universal brotherhood." Madame Blavatsky's theosophy would, however, not fall under this definition, as it is non-theistic
Adherents of Theosophy maintain that it is a "body of truth" that forms the basis of all religions. Theosophy, some claim, represents a modern face of Sanatana Dharma, "the eternal truth," as the proper religioncitation needed].
