“That being said, is there anything to say in support of utopian thinking? Everything, if the meaning of the word is somewhat restricted. If utopia means the highest set of values we want to defend and see implemented in social life, nothing prevents us from hanging on to all of them even if we know that they will never be perfectly compatible with each other. If utopia is a regulative idea of the optimum and not an assurance that we have mastered the skill to produce the optimum, then utopia is a necessary part of our thinking. But it would be a puerile fantasy to pretend that we know how to rid the world of scarcity, suffering, hatred, and injustice: nobody knows that. Whatever can be done in softening these conditions can be done only in specific points, on small scales, by inches. That this should be so unacceptable to the genuine utopian mentality which looks for the vision of the Last Day, the great leap, the final battle; everything else seems (and is, indeed) grey, boring, lacking pathos, requiring specific knowledge instead.”
