An attitude to life which seeks fulfillment in the single-minded pursuit of wealth - in short, materialism - does not fit into this world, because it contains within itself no limiting principle, while the environment in which it is placed is strictly limited.

We think work with the brain is more worthy than work with the hands. Nobody who thinks with his hands could ever fall for this.

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.

I started by saying that one of the most fateful errors of our age is the belief that the problem of production has been solved. This illusion, I suggested, is mainly due to our inability to recognize that the modern industrial system, with all its intellectual sophistication, consumes the very basis on which is has been erected. To use the language of the economist, it lives on irreplaceable capital which it cheerfully treats as income.

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

Eagles come in all shapes and sizes, but you will recognize them chiefly by their attitudes.
