The Chalice: Mind Amplifiers

The Chalice is a recurring psychedelic salon held at the Berkeley Alembic the first Wednesday of every month. Instead of the mainstream focus on clinical trials, legal frameworks, and psychotherapy, the Chalice will draw from the deeper humanistic wells of history, poetry, the gods, ethnobotany, humor, and mystery. We are less interested in fetishizing psychedelic substances or psychedelic experiences than in cultivating psychedelic culture and exploring what it means to be psychedelic people.

For this month’s Chalice, we will be joined by writer, artist, technology critic, and OG mind amplifier Howard Rheingold. A Bay Area legend, a guiding light of arts, technology, and virtual community, Howard is a marvelous example of a psychedelicized person who has turned his expanded (and sympathetic) mind on the changing world at large — and especially the consciousness culture of tech, where he was often ahead of the curve. He has written books about consciousness (1988’s Exploring the World of Lucid Dreaming), mind-amplifying technology (1991’s Virtual Reality), the birth of social media (1993’s The Virtual Community), and the social revolutions growing from the hybrid of mobile telephones, digital media, and the Internet (2002’s Smart Mobs). In 2005, he gave a TED talk about the need for an interdisciplinary understanding of cooperation that has been viewed more than a million times. He has worked with the Institute for the Future on the topic of cooperation studies, and taught digital journalism and social media literacies at Berkeley and Stanford. He has also been painting for decades, and is currently crafting “magical objects of paint and light” using wood, acrylics, and arduino-controlled LEDs. If we are lucky he might bring one!

This first half of this event will be streamed online.

The co-hosts for Chalice are Erik Davis, author and Alembic co-founder; Maria Mangini, co-founder of the Women’s Visionary Council and old-school head; and Christian Greer, currently a lecturer on counterculture at Stanford University. The first half of each gathering will feature a talk or special guest interview; the second half of the evening is designed to develop the community, sometimes with breakout groups, story hours, and peer-to-peer discussion, and always with more questions than answers.
