It is a mistake to think of creative activity as something unusual

The progress of science is the discovery at each step of a new order which gives unity to what had seemed unlike.

Science is a very human form of knowledge. We are always at the brink of the known; we always feel forward for what is to be hoped. Every judgment in science stands on the edge of error and is personal. Science is a tribute to what we can know although we are fallible.

Man is not the most majestic of the creatures; long before the mammals even, the dinosaurs were far more splendid. But he has what no other animal possesses: a jigsaw of faculties, which alone, over three thousand million years of life, made him creative. Every animal leaves traces of what he was. Man alone leaves traces of what he created.

The paradox of knowledge is not confined to the small, atomic scale; on the contrary, it is as cogent on the scale of man, and even of the stars.

Knowledge is an unending adventure at the edge of uncertainty.

Whether our work is art or science or the daily work of society, it is only the form in which we explore our experience which is different.
