We like to think of individuals as unique. Yet if this is true of everyone, then we all share the same quality, namely our uniqueness. What we have in common is the fact that we are all uncommon. Everybody is special, which means that nobody is. The truth, however, is that human beings are uncommon only up to a point. There are no qualities that are peculiar to one person alone. Regrettably, there could not be a world in which only one individual was irascible, vindictive or lethally aggressive. This is because human beings are not fundamentally all that different from each other, a truth postmodernists are reluctant to concede. We share an enormous amount in common simply by virtue of being human, and this is revealed by the vocabularies we have for discussing human character. We even share the social processes by which we come to individuate ourselves.
