“It is sometimes hard even for biologists to remember that sex is merely a genetic joint venture.”

“Piaget, who was originally trained as a biologist, views intellectual development as an interaction of an inherited genetic program with the environment. It is no coincidence that he calls this conception "genetic epistemology," in effect the study of the hereditary unfolding of understanding.”

“I would rather remember even if sometimes it can be very painful.”

“Virtue's a mere name,
Or 'tis high venture that achieves high aim.”

“Among men, sex sometimes results in intimacy; among women, intimacy sometimes results in sex.”

“It is kind of hard to hold a lot in. But for me… it’s sometimes even harder to let it out.”

“You can’t remember sex. You can remember the fact of it, and recall the setting, and even the details, but the sex of the sex cannot be remembered, the substantive truth of it, it is by nature self-erasing, you can remember its anatomy and be left with a judgment as to the degree of your liking of it, but whatever it is as a splurge of being, as a loss, as a charge of the conviction of love stopping your heart like your execution, there is no memory of it in the brain, only the deduction that it happened and that time passed, leaving you with a silhouette that you want to fill in again.”

“Love is essential. Sex, a mere accident.”

“No practical biologist interested in sexual reproduction would be led to work out the detailed consequences experienced by organisms having three or more sexes; yet what else should he do if he wishes to understand why the sexes are, in fact, always two?”

“If two bodies merely join together, that is not sex, it is merely pleasure. Sex goes far beyond pleasure. In sex, relaxation and tension go hand in hand, as do pain and pleasure, shyness and the courage to go beyond one’s limits.”
