Why does the sexual appetite cause so much unspeakable joy and irrational misery, so much suicidal and homicidal madness, and so much absurd theological ranting? Because every sexual choice is going to play a role in determining the temperament and talents of the next generation, and of all future generations who will inherit the earth from us. To be simple about it for once, a single friendly fuck can fill a continent with morons or geniuses in only a few thousand years.
