If I limit myself to knowledge that I consider true beyond doubt, I minimize the risk of error but I maximize, at the same time, the risk of missing out on what may be the subtlest, most important and most rewarding things in life.

The technology of mass production is inherently violent, ecologically damaging, self-defeating in terms of non-renewable resources, and stultifying for the human person.

At present, there can be little doubt that the whole of mankind is in mortal danger, not because we are short of scientific and technological know-how, but because we tend to use it destructively, without wisdom. More education can help us only if produces more wisdom.

That soul-destroying, meaningless, mechanical, moronic work is an insult to human nature which must necessarily and inevitably produce either escapism or aggression, and that no amount of 'bread and circuses' can compensate for the damage done-these are facts which are neither denied nor acknowledged but are met with an unbreakable conspiracy of silence-because to deny them would be too obviously absurd and to acknowledge them would condemn the central preoccupation of modern society as a crime against humanity.

By means of trees, wildlife could be conserved, pollution decreased, and the beauty of our landscapes enhanced. This is the way, or at least one of the ways, to spiritual, moral, and cultural regeneration.

Any intelligent fool can invent further complications, but it takes a genius to retain, or recapture, simplicity.
