There are three things healthy people most need to do - to be creatively productive, to render service, and to act in accordance with their moral impulses. In all three respects modern society frustrates most people most of the time.

The real problems of our planet are not economic or technical, they are philosophical. The philosophy of unbridled materialism is being challenged by events.

Few can contemplate without a sense of exhilaration the splendid achievements of practical energy and technical skill, which, from the latter part of the seventeenth century, were transforming the face of material civilization, and of which England was the daring, if not too scrupulous, pioneer.

If greed were not the master of modern man, how could it be that the frenzy of economic activity does not abate as higher standards of living are attained, and that it is precisely the richest societies which pursue their economic advantage with the greatest ruthlessness?

The art of living is always to make a good thing out of a bad thing.

A way of life that ever more rapidly depletes the power of the Earth to sustain it and piles up ever more insoluble problems for each succeeding generation can only be called violent.

Our task is to look at the world, and see it whole.
