A Textbook of Theosophy is a religious philosophy/theosophy studies classic by C.W. Leadbeater. "There is a school of philosophy still in existence of which modern culture has lost sight." In these words Mr. A.P. Sinnett began his book, The Occult World, the first popular exposition of Theosophy, published thirty years ago. [Namely in 1881.] During the years that have passed since then, many thousands have learned wisdom in that school, yet to the majority its teachings are still unknown, and they can give only the vaguest of replies to the query, "What is Theosophy?" Charles Webster Leadbeater (16 February 1854 - 1 March 1934) was a member of the Theosophical Society, author on occult subjects and co-initiator with J. I. Wedgwood of the Liberal Catholic Church. Originally a priest of the Church of England, his interest in spiritualism caused him to end his affiliation with Anglicanism in favour of the Theosophical Society, where he became an associate of Annie Besant. He became a high-ranking officer of the society, but resigned in 1906 amid a sex scandal. Accusations of his detractors were never proven, and after Annie Besant became President of the Society, he was readmitted in 1908. Leadbeater went on to write over 69 books and pamphlets as well as maintain regular speaking engagements. His efforts on behalf of the society assured his status as one of its leading members until his death in 1934.
