“Chaos magic, also spelled chaos magick, is a contemporary magical practice. It was initially developed in England in the 1970s, drawing heavily from the philosophy of artist and occultist Austin Osman Spare. Sometimes referred to as “success magic” or “results-based magic”, chaos magic claims to emphasize the attainment of specific results over the symbolic, ritualistic, theological or otherwise ornamental aspects of other occult traditions.

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.

Early leading figures include Peter J. Carroll and Ray Sherwin.

Chaos magic rejects the existence of absolute truth, and views all occult systems as arbitrary symbol-systems that are only effective because of the belief of the practitioner. Chaos magic thus takes an explicitly agnostic position on whether or not magic exists as a supernatural force, with many chaos magicians expressing their acceptance of a psychological model as one possible explanation.

The word chaos was first used in connection with magic by Peter J. Carroll in Liber Null (1978), where it is described as “the ‘thing’ responsible for the origin and continued action of events.” Carroll goes on to say that “It could as well be called ‘God’ or ‘Tao’, but the name ‘Chaos’ is virtually meaningless and free from the anthropomorphic ideas of religion.”
