Tragedy is the highest form of art.
Perhaps the inevitable tragedy of our complex civilization is that we must be specialists in our fields - and our fields have become increasingly difficult, so that communication is nearly impossible.
I don't think I'm morbid by nature. Serious writers have always written about serious subjects. Lighthearted material doesn't appeal to me, and I don't read it. I think I'm a realist, with a realistic sensibility of history and the tragedy of history.
