Chaos Magic

Chaos magic has been described as a union of traditional occult techniques and applied postmodernism – particularly a postmodernist skepticism concerning the existence or knowability of objective truth. Chaos magicians subsequently treat belief as a tool, often creating their own idiosyncratic magical systems and frequently borrowing from other magical traditions, religious movements, popular culture and various strands of philosophy.
