Peter J. Carroll, one of the founders of chaos magic, passed away earlier this week. Carroll was the author of Liber Null and Psychonaut in 1987 and Liber Kaos in 1992, two books that would define the chaos magic system for a whole generation of practitioners. Carroll's death was announced on his blog Specularium on April 25th.
The Wizard has gone.
The celebrated occultural author, teacher and innovator Peter J Carroll passed away unexpectedly in the early hours of Wednesday 22nd April 2026. He was a star whose books and ideas changed the lives of millions. He was instrumental in the birth of Chaos Magick, one the most significant new magical/philosophical streams of thought of our times.
He is survived by a wife and two daughters. Pete will be cremated in a simple private ceremony for close friends and family. He leaves a great legacy which will be the subject of a longer eulogy and memorial in due course.
An online memorial page will be hosted on this site in coming days.
Chaos magic brought an innovative, experimental approach to magick theory based on chaos theory and the manipulation of quantum uncertainty. Liber Kaos in particular was a big influence on several key aspects of my approach to magick. It highlighted the importance of experimentation and exploring magick in as scientific a manner as possible.
On this blog I have written about my operant equation, a calculation adapted from Carroll's work. As you can see from my explanation of its terms I do not agree entirely with Carroll's version, but the original idea was his and it was Liber Kaos that first got me thinking about the factors that go into a successful magical operation in this particular way.
Another big influence chaos magic had on my work is in how I structure rituals when using the Thelemic or Golden Dawn ritual forms. I open a space, invoke energies, build my intent, and then disconnect from it in order to release it into the universe rather than banishing my way back "down" following the operation. This structure is inspired by the vortex - sigil - banish by laughter structure from chaos magic, and in my experience it works a lot better than the traditional method.
Finally, chaos magick brought the discussion of chaos theory and quantum physics into esotericism. While I realize many New Agers throw "quantum" around these days like a synonym for "awesome," I am of the opinion that (A) magick must operate by manipulating probabilities and (B) these probability shifts must occur at the quantum level of reality. Liber Kaos introduced those ideas to my model of magick, and they have served me well ever since in my attempts to unravel that nature of the paranormal.
Unto Peter J. Carroll, from whose eyes the veil of life hath fallen, may he be granted the accomplishment of his will, yea, the accomplishment of his will.
