John Michael Greer (born 1962) is an American writer anddruid who writes on religious, environmentalist, andoccult topics.

Greer was born inBremerton, Washington and was raised in theSeattle area. He is an initiate inFreemasonry and theHermetic Order of the Golden Dawn.^[1]

In a 2005 abstract, calledHow Civilizations Fall: A Theory of Catabolic Collapse, he wrote an ecological model of collapse in which production fails to meet maintenance requirements for existing capital.^[2] Philosopher of scienceJerome Ravetz summarized Greer's theory in his 2006 book chapter, titled "When Communication Fails: A Study of Failures of Global Systems."^[3] Ravetz wrote:

A simple but powerful model of 'catabolic collapse', a self-reinforcing cycle of contraction converting most capital to waste, has been produced by John Michael Greer (Greer 2005). His activity in the 'contemporary nature spirituality movement' in Oregon has not prevented him from producing a model in the best economic style. His key variables are resources, capital, waste and production; crisis occurs when production fails to meet maintenance requirements for existing capital. The continuing degradation of the infrastructure, particularly in the USA, provides evidence for his approach. He claims that he can account for key features of historical collapse, and suggests parallels between successional processes in non-human ecosystems and collapse phenomena in human societies.^[3]

InThe King in Orange (2021), Greer analyses the contemporary American political landscape throughclass analysis and occult practices. Focusing on the election and opposition toDonald Trump as president of the United States, Greer predicts a continuing combination of magic and politics from the various class factions of the country. He criticised the public magical workings ofliberal occultists, arguing that political magic should be kept secret to prevent opposing magicians from tampering with the working.^[4]

Greer has written many novels, including a series of eleven fantasy novels based on the worlds created byH.P. Lovecraft and hisCthulhu Mythos entitled "The Weird of Hali".^[5]

Writing inThe Futurist magazine, Rick Docksai declared that Greer's bookThe Ecotechnic Future is "as realistic a portrayal of the end of civilization as one is likely to find."^[6] It was also positively reviewed inChoice: Current Reviews for Academic Libraries^[7] and was recommended in the industry journalEnergy Policy.^[8] TheInternational Journal of Agricultural Sustainability referred to his bookThe Wealth of Nature as "challeng[ing] the paradigms that underlie the complex system of wealth distribution we know as economics."^[9]

His bookThe New Encyclopedia of the Occult was selected as a reference text in 2005 byAmerican Libraries^[10] and noted byBooklist^[11] andPublishers Weekly.^[12]
