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

The belief that we can manage the Earth and improve on Nature is probably the ultimate expression of human conceit, but it has deep roots in the past and is almost universal.

It is often by a trivial, even an anecdotal decision, that we direct our activities into a certain channel, and thus determine which of the potential expressions of our individuality become manifest. Usually we know nothing of the ultimate orientation or of the outlet toward which we travel, and the stream sweeps us to a formula of life from which there is no returning. Every decision is like a murder, and our march forward is over the stillborn bodies of all our possible selves that will never be.

Eradication of microbial disease is a will-o'-the-wisp; pursuing it leads into a morass of hazy biological concepts and half truths.

The word "wilderness" occurs approximately three hundred times in the Bible, and all its meanings are derogatory.

Human life implies adventure, and there is no adventure without struggles and dangers.

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.
