Men are naturally most impressed by diseases which have obvious manifestations, yet some of their worst enemies creep on them unobtrusively.

Human destiny is bound to remain a gamble, because at some unpredictable time and in some unforeseeable manner nature will strike back.

Biologically, man is still the great amateur of the animal kingdom; he is unique in his lack of anatomical and physiological specialization.

Clearly, health and disease cannot be defined merely in terms of anatomical, physiological, or mental attributes. Their real measure is the ability of the individual to function in a manner acceptable to himself and to the group of which he is a part.

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.

As far as life is concerned, there is no such thing as "Nature". There are only homes. Home is that environment to which the individual has become adapted; and almost everything is unnatural outside his range of adaptation. Harmonious equilibrium with nature is an abstract concept with a Platonic beauty but lacking the flesh and blood of life. It fails, in particular, to convey the creative emergent quality of human existence.
