A vice in common can be the ground of a friendship but not a virtue in common. X and Y may be friends because they are both drunkards or womanizers but, if they are both sober and chaste, they are friends for some other reason.
W. H. AudenAs readers, we remain in the nursery stage so long as we cannot distinguish between taste and judgment, so long, that is, as the only possible verdicts we can pass on a book are two: this I like; this I don't like. For an adult reader, the possible verdicts are five: I can see this is good and I like it; I can see this is good but I don't like it; I can see this is good and, though at present I don't like it, I believe that with perseverance I shall come to like it; I can see that this is trash but I like it; I can see that this is trash and I don't like it.
W. H. Auden
