occultism (n.)

"the doctrine, principles, or practices of occult sciences," 1870, from occult + -ism. Related: Occultist.

Occultism, I should add, is to be distinguished from the primitive magic described by anthropologists, which is prescientific, prephilosophical, and perhaps prereligious, whereas occultism is a pseudo-science or system of pseudo-sciences, often supported by an irrationalist philosophy, and always exploiting the disintegrated débris of preexisting religions. [E.R. Dodds, "The Greeks and the Irrational," 1951, footnote]
