Truth and Beauty (perhaps Keats was wrong in identifying them: perhaps they have the relation of Wit and Humour, or Rain and Rainbow) are of interest only to hungry people. There are several kinds of hunger. If Socrates, Spinoza, and Santayana had had free access to a midnight icebox we would never have heard of them. Shall I be ashamed of my little mewing truths?. . . I ask to be forgiven: they are such tiny ones.
The 60s were a continuation of the 50s much more than people realized. Certainly in some countries, like Britain, there was still a culture of deference, whereas in the 70s we really are in a time of angry transition. The generation that came into young adulthood in the 70s couldn't find jobs; that wasn't true in my generation. They entered a time when two depressing things hit them both at the same time.
