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

But too often the goal of the planners is a universal gray state of health corresponding to absence of disease rather than to a positive attribute conducive to joyful and creative living. This kind of health will not rule out and may even generate another form of ill, the boredom which is the penalty of a formula of life where nothing is left unforeseen.

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.

The earth is literally our mother, not only because we depend on her for nurture and shelter but even more because the human sepcies has been shaped by her in the womb of evolution. Our salvation depends upon our ability to create a religion of nature.

One may wonder indeed whether the pretense of superior health is not itself rapidly becoming a mental aberration.

Social evolution may be the result of intention, but it rarely, if ever, produces the result intended.

Human life is now molded to a large extent by the changes that man has brought about in his external environment and by his attempts at controlling body and soul.
