“Past and present religious atrocities have occured not because we are evil, but because it is a fact of nature that the human species is, biologically, only partly rational. Evolution has meant that our prefrontal lobes are too small, our adrenal glands are too big, and our reproductive organs apparently designed by committee; a recipe which, alone or in combination, is very certain to lead to some unhappiness and disorder.”

“Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which we live. The earth is our home. Unless we preserve the rest of life, as a sacred duty, we will be endangering ourselves by destroying the home in which we evolved, and on which we completely depend.”

“Perhaps we were each allotted only a certain amount of love - enough for only an initial meeting - a serendipitous clumsiness. When it leaves to find others, the difficulty begins because we are faced with our humanness, our past, our very being.”

“For our own species, evolution occurs mostly through our behavior. We innovate new behavior to adapt.”

“Great rationalizations. All of which her adrenal gland middle-fingered and then carried right on.”
