Our culture loves a retro moment, and not only in its fashion trends. A common social, cultural, and political phenomenon is the resurgence, or revival, of beliefs, practices, and aesthetics from bygone eras. And there’s as much to learn about what these affinities say regarding the present moment as there is regarding history. One slice of this occurrence is the modern era’s rediscovery of seminal psychedelic and visionary science fiction-inflected ideas from the 1970s, especially by authors like Philip K. Dick, Terence McKenna, and Robert Anton Wilson. Based on his recent book High Weirdness: Drugs, Esoterica, and Visionary Experience in the Seventies, Erik Davis lectures on the topic at the Philosophical Research Society in the presentation High Weirdness Then & Now: Occult Revival in the ’70s and Today. Arrive early for a music session featuring vintage and contemporary occult music curated by Davis, or stay home and enhance your mood as you see fit because there will also be a ticketed live-stream.

The Philosophical Research Society, 3910 Los Feliz Blvd., Los Feliz; Mon., Oct. 28, 7:30-9 p.m.; $10. prs.org.
