occultism

This term describes a pursuit of hidden knowledge that claims to operate beyond the reach of conventional science or public awareness. It carries a heavy connotation of secrecy and exclusivity, often evoking images of clandestine societies, ancient grimoires, and ritualistic practices. As an uncountable noun, it refers to the general field of study or the belief system itself. It does not typically take a plural form because it represents an abstract concept or a collective body of knowledge rather than a discrete object.
