" One thinks of the flamboyant student slogan of Paris 1968: ‘Be realistic: demand the impossible!’’ For all its hyperbole, the slogan is accurate enough. What is realistically needed to repair society is beyond the powers of the prevailing system, and in that sense is impossible. But it is realistic to believe that the world could in principle be greatly improved. Those who scoff at the idea that major social change is possible are full-blown fantasists. The true dreamers are those who deny that anything more than piecemeal change can ever come about. "
