Millions upon millions of years ago, when the continents were already formed and the principal features of the earth had been decided, there existed, then as now, one aspect of the world that dwarfed all other ... a mighty ocean, resting uneasily to the east of the largest continent, a restless ever-changing, gigantic body of water that would later be described as Pacific.

The dead are dead but they rely on us to fulfill their hopes.

I feel myself the inheritor of a great background of people. Just who, precisely, they were, I have never known. I might be part Negro, might be part Jew, part Muslim, part Irish. So I can't afford to be supercilious about any group of people because I may be that people.

Although most of us know Vincent van Gogh in Arles and Paul Gauguin in Tahiti as if they were neighbors -- somewhat disreputable but endlessly fascinating -- none of us can name two French generals or department store owners of that period. I take enormous pride in considering myself an artist, one of the necessaries.

I am a humanist because I think humanity can, with constant moral guidance, create reasonably decent societies. I think that young people who want to understand the world can profit from the works of Plato and Socrates, the behaviour of the three Thomases, Aquinas, More and Jefferson - the austere analyses of Immanuel Kant and the political leadership of Abraham Lincoln and Franklin Roosevelt.

We risk great peril if we kill off this spirit of adventure, for we cannot predict how and in what seemingly unrelated fields it will manifest itself. A nation that loses its forward thrust is in danger, and one of the most effective ways to retain that thrust is to keep exploring possibilities. The sense of exploration is intimately bound up with human resolve, and for a nation to believe that it is still committed to a forward motion is to ensure its continuance.

Contrary to what people think, I slave over my books.
