With Matthew Arnold it is assumed that education can make him so, that is, that education, the right education, can develop our full potential and render us "perfect." The other four utopias are already inhabited by good people, or in the case of Swift by good quadrupeds. The question that arises in these cases is "What has made them good?" or more universally "What makes people good?" The answer to this query, I think, will take us to the essential problem, the very crux of the utopian idea. I shall leave the thought for you to wrestle with.
My other observation is related, I believe. It is that the utopian phenomenon is linked to a transcendent vision, that is, to our religious consciousness. I mentioned this earlier when I was discussing Rabelais' Abbey of Thélème. But it seems fairly obvious in that case. 10 In the others, I would say, it springs from even a deeper source, from that striving for perfection which arises naturally from the depths of the human heart. And in one idiom or another we all pray "Thy kingdom come" and in our innermost being desire that realization.
