What happens in the mind of man is always reflected in the disease of his body.

There is a demon in technology. It was put there by man and man will have to exorcise it before technological civilization can achieve the eighteenth-century ideal of humane civilized life.

Each civilization has its own kind of pestilence and can control it only by reforming itself.

The wooing of the Earth thus implies much more than converting the wilderness into humanized environments. It means also preserving natural environments in which to experience mysteries transcending daily life and from which to recapture, in a Proustian kind of remembrance, the awareness of the cosmic forces that have shaped humankind.

Wherever human beings are concerned, trend is not destiny.

Nature always strikes back. It takes all the running we can do to remain in the same place.

In man, at least, satisfaction is commonly followed by boredom.
