“From a Darwinian perspective, sexual jealousy is easily understood. Natural selection of our wild ancestors plausibly favored males who guarded their mates for fear of squandering economic resources on other men’s children. On the female side, it is harder to make a Darwinian case for the sort of vindictive jealousy . . . No doubt hindsight could do it, but I want to make a different point. Sexual jealousy may in some Darwinian sense accord with nature, but “Nature, Mr. Allnutt, is what we are put in this world to rise above.” Just as we rise above nature when we spend time writing a book or a symphony rather than devoting our time to sowing our selfish genes and fighting our rivals, so mightn’t we rise above nature when tempted by the vice of sexual jealousy? I, for one, feel drawn to the idea that there is something noble and virtuous in rising above naturein this way. I admit that I have, at times in my life, been jealous, but it is one of the things I now regret. Assuming that such practical matters as sexually transmitted diseases and the paternity of children can be sorted out (and nowadays DNA testing will clinch that for you if you are sufficiently suspicious, which I am not), what, actually, is wrong with loving more than one person? Why should you deny your loved one the pleasure of sexual encounters with others, if he or she is that way inclined? The British writer Julie Burchill is not somebody I usually quote . . . but I was struck by one of her remarks. I can’t find the exact quote, but it was to the effect that, however much you love your mate (of either sex in the case of the bisexual Burchill) sex with a stranger is almost always more exciting, purely because it is a stranger. An exaggeration, no doubt, but the same grain of truth lurks in Woody Allen’s “Sex without love is an empty experience, but as empty experiences go it’s one of the best.”"
Ladies and Gentlemen, meet biology’s version of Richard Posner, minus any sense of how people actually think or act. What’s the argument here? That jealousy is a legitimate emotion because it is genetically based (for men, but not for women) or that regardless of the Darwinian pull, it is something that women should must now rise above, because Dawkins wants to step out?
