"I feel transported from the modern to a Mesozoic era, freed from the blindness caused by our clocked environment of time. Ages turn to seconds as I voyage back and forth. Man becomes a recent advent among Earth's contending forms, and civilization but a flash in evolutionary progress. Surrounded by wildness I become less aware of my individuality than the life stream individuals manifest: that tenuous, immortal quality probing an unknown future and trailing, unbroken, beyond the vaguest past. Thus stripped of my culture's armor, I am an animal among various others, emerged to represent my species' progress, the momentary form and outlook of mankind. Whether in Florida's Everglades, Tanzania's Serengeti, or Java's Udjung Kulon, I see animals about me as earthly experiments with life; and so I feel myself. Each of us represents a life stream attempting to survive, to take advantage of every opportunity arising. The heron lengthens its legs to wade. The lion sharpens its teeth to kill. The rhinoceros thickens its skin for protection. Man develops his intellect to gain domination of the Earth, and by comparison, the speed with which he has gained this domination is astounding–another of those exponential curves that mount like an explosion. In civilization's sky-scraping cities I feel my superiority to lower animals confirmed by man's unchallenged rule. I view other creatures with a god's aloofness; for I have intellect, and they, no more than instinct. But surrounded by wildness, representing the human life stream with diverse competing life streams close at hand, I start doubting my superiority. I am struck by the physical perfection of other species in contrast to my own, amazed at the beauty, health and balance nature has achieved through instinct's influence. I ask myself what the intellect has done to warrant its prestige. As Earth's most messy, destructive and defective animal, man's record gives him little cause for pride. Our present intellectual superiority is no guarantee of great wisdom or survival power in our genes. Anthropologists often warn that Homo sapiens may be only an overspecialized branch on the trunk of evolution."
