Clairvoyance is one of Charles Webster Leadbeater's most systematic expositions of "second sight," arranging visionary perception into categories such as simple clairvoyance, clairvoyance in space, and clairvoyance in time. Written in the lucid, classificatory prose characteristic of late Victorian occult scholarship, the book blends anecdote, metaphysical theory, and practical caution. Its literary context is the Theosophical revival, where Eastern religious concepts, Spiritualist phenomena, and scientific language were combined to argue for unseen planes of reality. Leadbeater, a former Anglican clergyman who became a prominent member of the Theosophical Society, wrote from within a milieu deeply invested in occult investigation and spiritual evolution. His association with figures such as Helena Blavatsky and Annie Besant shaped his conviction that clairvoyance was not supernatural fantasy but a latent human faculty capable of disciplined development. His clerical background also informs the book's moral seriousness and hierarchical vision of spiritual progress. This volume is recommended to readers interested in esotericism, Victorian intellectual history, comparative religion, and the genealogy of modern New Age thought. Whether approached as spiritual instruction or as a cultural document, Clairvoyance remains an influential and revealing text.
