“No group-living nonhuman primate is monogamous, and adultery has been documented in every human culture studied- including those in which fornicators are routinely stoned to death. In light of all of this bloody retribution, it's hard to see how monogamy comes "naturally" to our species. Why would so many risk their reputations, families, careers- even presidential legacies- for something that runs against human nature? Were monogamy an ancient, evolved trait characteristic of our species, as the standard narrative insists, these ubiquitous transgressions would be infrequent and such horrible enforcement unnecessary. No creature needs to be threatened with death to act in accord with its own nature.”

“The destructive impulse with respect to nature all too often has psychological causes that go beyond the greed for material resource or the need to domesticate an environment. There is too often a deliberate rage and vengefulness at work in the assault on nature and its species, as if one would project onto the natural world the intolerable anxieties of finitude which hold humanity hostage to death. ”

“Marriage," "mating," and "love" are socially constructed phenomena that have little or no transferable meaning outside any given culture. The examples we've noted of rampant ritualized group sex, mate-swapping, unrestrained casual affairs, and socially sanctioned sequential sex were all reported in cultures that anthropologists insist are monogamous simply because they've determined that something they call "marriage" takes place there. No wonder so many insist that marriage, monogamy, and the nuclear family are human universals. With such all-encompassing interpretations of the concepts, even the prairie vole, who "sleeps with anyone," would qualify.”

“My argument has always been that nature has a master plan pushing every species toward procreation and that it is our right and even obligation as rational human beings to defy nature's fascism. Nature herself is a mass murderer, making casual, cruel experiments and condemning 10,000 to die so that one more fit will live and thrive.”

“I am convinced that the act of thinking logically cannot possibly be natural to the human mind. If it were, then mathematics would be everybody's easiest course at school and our species would not have taken several millennia to figure out the scientific method.”

“The distinctiveness that we have so assiduously ascribed to ourselves as humans is, in reality, an accident of history. Imagine, for instance, how much more distinct we could have claimed our species to be had all the great apes become extinct before we began pondering our position in the world of nature. If vervet monkeys were our closet relatives, humans would indeed appear to stand separate. Equally, if the species of hominid that links us to our common ancestor with the African apes had not become extinct, the gap between us and chimpanzees would be closed all the way. Gradations between human and ape would be present at every step, and our revered distinctiveness would vanish. It is simply a contingent fact of history that certain species did become extinct during the past five million years, leaving us to compare ourselves with the African apes as our closest living relatives. And it is a sobering fact of current history that the comparison between humans and apes may soon become virtually artificial, as each species of ape faces extinction in its natural populations. If this happens, it means we will lose the opportunity to learn about ourselves from our nearest living relatives, just at the time that we have indeed recognized them as our relatives. It also means that we will have frittered away our one remaining chance to allow our sibling species to live the way of life for which they, and we, co-evolved across the millennia.”
