Utopian thinking, and utopias as a genre, flourished as forms of the imaginary until recently. The emergence of the genre, with Thomas More, emphasizing spatial arrangement and with Louis-Sébastien Mercier invoking future orientation, I argue, is illuminated by placing them next to the economic enclosures of their time. Their utopias, however, closed off both the individual and time from the capitalist changes around them, allowing for little or no variation or expression of self. Thus, their imagined virtuous societies actually sought (...) to foreclose the future and other spaces. The paradox is that capitalist development, with its admitted inequities and horrors, favored an expansive self and vital societies, which carry with them their own virtues. In spite of the ameliorative tendencies of utopias, their limitations, that is, their closed-mindedness, slowly but surely discredited the genre itself. Its place has been taken today by science fiction, futurist studies and the exercise of the imaginary in terms of social science. (shrink)
