"Theosophy is a word and a concept known since antiquity, but commonly understood in the modern era to describe the studies of religious philosophy and metaphysics as originating with Helena Petrovna Blavatsky from the 1870s. In this context, theosophy holds that all religions are attempts by the "Spiritual Hierarchy" to help humanity in evolving to greater perfection, 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."
