Occultism

The term occultism derives from occult, itself adopted from the Latin word occultus, meaning “hidden” or “secret.” In medieval and early modern Europe this term had been used in reference to “occult properties,” or forces that, even if invisible to the human eye, were believed to exist within material objects. In the 16th century the term occult gained additional meanings, coming to also describe specific traditions of thought, usually called “occult sciences” or “occult philosophies.” Among the traditions repeatedly labeled under these terms were alchemy, astrology, and magia naturalis (“natural magic”), all of which are now typically regarded as forms of esotericism.
