Isis unveiled, Volume 1 (of 2), Science

The work challenges orthodox science and theology by arguing that ancient esoteric traditions preserve a systematic body of knowledge about psychic phenomena, the ether or astral medium, and latent human powers. It reviews mystical and philosophical systems, critiques materialist and positivist explanations, and surveys contemporary theories of mesmerism, mediumship, and related experiments. Chapters examine lost arts, elemental beings, healing by will, and the relation of visible and invisible forces, proposing cyclical evolution and an occult framework intended to reconcile spiritual doctrine with empirical inquiry.
