The system of nature, of which man is a part, tends to be self-balancing, self-adjusting, self-cleansing. Not so with technology.

It is doubly chimerical to build peace on economic foundations which, in turn, rest on the systematic cultivation of greed and envy, the very forces which drive men into conflict.

True art is the intermediary between man's ordinary nature and his higher potentialities.

The substance of man cannot be measured by Gross National Product.

Modern economic thinking...is peculiarly unable to consider the long term and to appreciate man's dependence on the natural world.

The modern world tends to be skeptical about everything that makes demands on man's higher faculties. But it is not at all skeptical about skepticism, which demands hardly anything.

Call a thing immoral or ugly, soul-destroying or a degradation to man, a peril to the peace of the world or to the well-being of future generations: as long as you have not shown it to be "uneconomic" you have not really questioned its right to exist, grow, and prosper.

Modern man talks of a battle with nature, forgetting that, if he won the battle, he would find himself on the losing side

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?
