The work of Erik Davis

Erik Davis is an American writer, scholar, journalist, and public speaker whose writings range from rock criticism to cultural analysis to esoteric explorations of California’s history.

I’ve been publishing stuff for over three decades, and most of it—with the exception of my books—resides on this site, which I have maintained through various iterations since the late 1990s. With Burning Shore now disseminating my fresher communiqués, Techgnosis.com acts more than ever as an archive of my work, including lectures, interviews, personal reflections, and almost a decade of the Expanding Mind podcast. Like Techgnosis itself, still in print and more relevant than ever, my stuff combines deep research with vivid writing and oracular aims that resonate through the years. For this revamped trans-temporal site, I and my team have introduced more robust searching and cross-linking of materials, as well as a roll-the-dice feature, which will hopefully allow for richer, more entertaining, and more synchronistic wanders through this wunderkammer.  — Erik
