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

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

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.

It fails, in particular, to convey the creative emergent quality of human existence.
