Occult science is the systematic research into or formulation of occult concepts in a manner that follows - in its method or presentation - the way natural science researches or describes phenomena of the physical world.
The idea of Occult Science appears in late-19th and early 20th century occultism, especially Theosophy, including:
- Helena Blavatsky (who describes it as "The science of the secrets of nature — physical and psychic, mental and spiritual");
- Rudolf Steiner, whose Occult Science, a sequel to his earlier work Theosophy, deals with the evolution of the human being and the cosmos, as well as referring to the attainment of supersensible knowledge;
- Alice Bailey, who brought the idea of occult science into association with esoteric astrology.
Kabbalah and Tarot have also been described as Occult sciences; Papus (Gerard Encausse)'s book originally published in French in 1889 as Le Tarot des Bohémiens: Le plus ancien Livre du monde, was translated into English in 1910 as The Tarot of the Bohemians: The Absolute Key to Occult Science.
