We still have to learn how to live peacefully, not only with our fellow men but also with nature.

The truly educated man is not a man who knows a bit of everything, not even the man who knows all the details of all subjects (if such a thing were possible): the “whole man” in fact, may have little detailed knowledge of facts and theories...but he will be truly in touch with the centre. He will not be in doubt about his basic convictions, about his view on the meaning and purpose of his life. He may not be able to explain these matters in words, but the conduct of his life will show a certain sureness of touch which stems from this inner clarity.

Is there enough to go around? What is enough? Who can tell us? Certainly not the economist who pursues economic growth as the highest of all values, and therefore has no concept of enough.

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.

Development does not start with goods; it starts with people and their education, organization, and discipline. Without these three, all resources remain latent, untapped, potential.

Infinite growth of material consumption in a finite world is an impossibility.

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