Techgnosis uncovers the hidden mystical and religious impulses that animate our contemporary obsessions with media and technology. It is a wild ride, chock full of curious characters, esoteric information and visionary insights. The book tells the story of the alchemical origins of electricity, the occult dimension of computer games, and the Zen of cybernetics. It reminds us of the irrational, even dreamlike underside of our supposedly rational machines. Techgnosis was first published in 1998, and it is now a cult classic, one of the key texts of the media underground. It has been translated into five languages. This updated edition will feature a new afterword, placing the book in our moment.
