Esotericism
The Invisible college of the Rosicrucians,
Theophilus Schweighardt Speculum sophicum rhodo-stauroticum, 1618Definition
Esotericism, properly, is the study of transmitted and secret knowledge of any kind. While the knowledge is generally philosophical or ethical and mystic, it can, in theory, be of any kind.
Many groups or schools of thought embrace an esoteric tradition or philosophy:
Freemasons, Gnosticism, Kabbalists, Esoteric Buddhists, Rosicrucians, Magic, Occultism, Scientology, G. I. Gurdjieff
Camp is esoteric [...]
A sensibility (as distinct from an idea) is one of the hardest things to talk about; but there are special reasons why Camp, in particular, has never been discussed. It is not a natural mode of sensibility, if there be any such. Indeed the essence of Camp is its love of the unnatural: of artifice and exaggeration. And Camp is esoteric - something of a private code, a badge of identity even, among small urban cliques. --Susan Sontag
