Davis grew up in the milieu of Southern California during the heyday and simultaneous decline of the 70's "lifestyle" revolution in North American culture of which his native state was considered the center.His early interest in philosophy led him to both study the history of philosophy and the folk contemporary "religions" and spiritual movements of his native state. His first critical and scholarly work of note began as a thesis on Philip K. Dick which he completed at Yale.

Davis became an independent scholar, author, lecturer, and freelance intellectual in the 80's and 90's.

His distinctive work continues to focus on the history of both material culture and the imaginative investment and subjectivity that haunts it.
