Some quotes are so succinct as comments in themselves they need no additional commentary.
Of course a short snippet of Orwell means you might want to read the entire essay. Bangs has, of course, found the most irreducibly eloquent and succint point in the Orwell essay. :)
One ought to be able to hold in one’s head simultaneously the two facts that Dali is a good draughtsman and a disgusting human being. The one does not invalidate or, in a sense, affect the other. The first thing that we demand of a wall is that it shall stand up. If it stands up, it is a good wall, and the question of what purpose it serves is separable from that. And yet even the best wall in the world deserves to be pulled down if it surrounds a concentration camp. In the same way it should be possible to say, ‘This is a good book or a good picture, and it ought to be burned by the public hangman.’ Unless one can say that, at least in imagination, one is shirking the implications of the fact that an artist is also a citizen and a human being.
