“I am a member of a fragile species, still new to the earth, the youngest creatures of any scale, here only a few moments as evolutionary time is measured, a juvenile species, a child of a species. We are only tentatively set in place, error prone, at risk of fumbling, in real danger at the moment of leaving behind only a thin layer of of our fossils, radioactive at that.”

“One species on the planet, and one species only, has reached the point of being able to have an impact on the evolutionary fortunes of all other species and upon the functioning of all ecosystems. We also have, in a way that is not true for any other species, a relationship to the planet as a whole and to the future. We live with all life.”

“The plague of mankind is the fear and rejection of diversity: monotheism, monarchy, monogamy and, in our age, monomedicine. The belief that there is only one right way to live, only one right way to regulate religious, political, sexual, medical affairs is the root cause of the greatest threat to man: members of his own species, bent on ensuring his salvation, security, and sanity. ”

“We are, perhaps uniquely among the earth’s creatures, the worrying animal. We worry away our lives, fearing the future, discontent with the present, unable to take the idea of dying, unable to sit still.”

“The future is too interesting and dangerous to be entrusted to any predictable, reliable agency. We need all the fallibility we can get. Most of all, we need to preserve the absolute unpredictability and total improbability of our connected minds.”

“As a survival-happy species, our successes are calculated in the number of years we have extended our lives, with the reduction of suffering being only incidental to this aim. To stay alive under almost any circumstances is a sickness with us. Nothing could be more unhealthy than to “watch one’s health” as a means of stalling death. The lengths we will go as procrastinators of that last gasp only demonstrate a morbid dread of that event. By contrast, our fear of suffering is deficient.”

“The oldest, easiest to swallow idea was that the earth was man's personal property, a combination of garden, zoo, bank vault, and energy source, placed at our disposal to be consumed, ornamented, or pulled apart as we wished.”
