Max Nettlau's Utopian Vision provides a historically grounded presentation of the entire literature of utopianism. Nettlau shows an encyclopaedic knowledge of the subject. He passionately believed that the value of utopian thinking and class struggle should not be underestimated as utopian desire exists in all of us. Utopian thinking, according to Nettlau, stimulates the imagination and awakens the desire to attain a better life for everyone. Nettlau argues that every idea begins as a utopia: some are realized; others are not. Utopian thinking also creates a desire for radical change in society without which no new reality could emerge. Every reality is first dreamed of and, then, the act of dreaming awakens the desire for realization. It is the same desire without which every piece of art would be unthinkable. When utopian ideas reach the masses, forces are released that build bridges into the future and make things possible that otherwise would only exist as dreamlike imaginings. Indeed, Nettlau claims that history is the record of utopian thought practically imagined.
