Utopias appear to be much easier to realize than formerly believed. We currently face a question that fills us with much more anguish: How to avoid their becoming definitively real? Utopias can made real. Life is moving toward utopias. And perhaps a new century is beginning, a century in which the intellectuals and the educated classes will dream about how to avoid utopias, and how to return to a non-utopian society, with less "perfection" and more freedom.
