"'Financial Psychedelia and the Commons' is an exceptionally innovative book in the field of social sciences. Andrea Fumagalli places the reader amidst counterculture and cyberculture, evoking the spirit of Grateful Dead's music and contemporary blows against the Empire that denounce capitalism for exploiting commons through its financial infrastructure." -- Stefano Lucarelli, University of Bergamo, Italy "Fumagalli's fascinating study reveals how traditions of US counterculture and contemporary radical economic projects share left libertarian tendencies. Particularly compelling is his argument that, despite the myriad ways in which digital technologies have been made to serve corporate and military interests, we can and should recuperate liberatory aspects that the utopian digital spirit of the 1990s still has to offer." -- Michael Hardt, Duke University, USA "Libertarianism is merging into a neo-fascism built by a plutocracy of narcissistic individualism, with a rejection of the fundamental human values of empathy, reviving eugenics as a dystopian political force. This book, derived from the psychedelic music of the Grateful Dead, is an apt warning of the dangers ahead." -- Guy Standing, SOAS University of London, UK.
