Andrew Anthony:

Nonetheless, Hitchens mentions a “narrow but quite deep difference” between himself and Dawkins. Unlike the evangelical biologist, he has no wish to convert everyone in the world to his point of view, even if it were possible. In other words, he savours the counterargument. Like John Stuart Mill, he is aware of the empty end of achieved objectives. The true satisfaction lies in the means. Although Hitchens is often seen as a provocateur or a contrarian, and both are indeed aspects of his character, at heart he’s incurably in love with the dialectic.

Right on. Let me quote this Nietzschean aphorism again:

Even if we were mad enough to consider all our opinions true, we should still not want them alone to exist: I cannot see why it should be desirable that truth alone should rule and be omnipotent; it is enough for me that it should possess great power. But it must be able to struggle and have great opponents, and one must be able to find relief from it from time to time in untruth – otherwise, it will become boring, powerless and tasteless to us, and make us the same.
