We know too much for one man to know too much.

Both the man of science and the man of action live always at the edge of mystery, surrounded by it.

The optimist thinks this is the best of all possible worlds. The pessimist fears it is true.

Discovery follows discovery, each both raising and answering questions, each ending a long search, and each providing the new instruments for a new search.

The open society, the unrestricted access to knowledge, the unplanned and uninhibited association of men for its furtherance-these are what may make a vast, complex, ever growing, ever changing, ever more specialized and expert technological world, nevertheless a world of human community.

We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita; Vishnu is trying to persuade the Prince that he should do his duty and, to impress him, takes on his multi-armed form and says, "Now I am become Death, the destroyer of worlds." I suppose we all thought that, one way or another.

We know too much for one man to know too much.
