It's a simplification to say that the men [during Stone Age] went to war to maintain their dominance over the women. The men would help dig agricultural ditches because they were superb farmers. That was very heavy lifting work. But then they just preened themselves, and put bird-of-paradise plumes [in their hair], and smoked dope.

Amazingly, we take for granted that instinct for survival, fear of death, must separate us from the happiness of pure and uninterpreted experience, in which body, mind, and nature are the same. This retreat from wonder, the backing away like lobsters into safe crannies, the desperate instinct that our life passes unlived, is reflected in proliferation without joy, corrosive money rot, the gross befouling of the earth and air and water from which we came.

I can watch elephants (and elephants alone) for hours at a time, for sooner or later the elephant will do something very strange... There is mystery behind that masked gray visage, and ancient life force, delicate and mighty, awesome and enchanted, commanding the silence ordinarily reserved for mountain peaks, great fires, and the sea.

I ... had what Kierkegaard called 'the sickness of infinitude,' wandering from one path to another with no real recognition that I was embarked upon a search, and scarcely a clue as to what I might be after. I only knew that at the bottom of each breath there was a hollow place that needed to be filled.

The sun is roaring, it fills to bursting each crystal of snow. I flush with feeling, moved beyond my comprehension, and once again, the warm tears freeze upon my face. These rocks and mountains, all this matter, the snow itself, the air- the earth is ringing. All is moving, full of power, full of light.

When we are mired in the relative world, never lifting our gaze to the mystery, our life is stunted, incomplete; we are filled with yearning for that paradise that is lost when, as young children, we replace it with words and ideas and abstractions - such as merit, such as past, present, and future - our direct, spontaneous experience of the thing itself, in the beauty and precision of this present moment.

There's an elegiac quality in watching [American wilderness] go, because it's our own myth, the American frontier, that's deteriorating before our eyes. I feel a deep sorrow that my kids will never get to see what I've seen, and their kids will see nothing; there's a deep sadness whenever I look at nature now.
