The lessons of relationship that our primordial ancestors learned are deeply encoded in the genetics of our neurobiological circuits of love. They are present from the moment we are born and activated at puberty by the cocktail of neurochemicals. It’s an elegant synchronized system. At first our brain weighs a potential partner, and if the person fits our ancestral wish list, we get a spike in the release of sex chemicals that makes us dizzy with a rush of unavoidable infatuation. It’s the first step down the primeval path of pair-bonding.

We like to romanticize the wild, raw, majestic beauty of nature. But when you take a closer look, nature is really just a giant fuckfest. That beautiful bird chirping? It's a mating call. That pretty little bird is trying to get laid. And why does the peacock have such beautiful feathers? To attract females. Because he's trying to get laid.

The red lipstick? It's supposed to signal fertility and readiness to mate. Just like the swollen red butt of a baboon. That tight-fitting little dress that shows off your curves? From the standpoint of evolutionary biology, big breasts represent a healthy mate who can feed a lot of offspring. That's why men are programmed to like big tits. When you show off your curves, what you're really doing is advertising to the whole world: "Look at me! I'm a healthy female! I'd be a perfect mate! Come mount me!

Human material culture - the buildings and roads and works that would strike any human as an obvious sign of intelligence - had for years seemed like part of an elaborate mating ritual to the starlings, useless and flamboyant as the peacock's tail.

There is no moment that exceeds in beauty that moment when one looks at a woman and finds that she is looking at you in the same way that you are looking at her. The moment in which she bestows that look that says, "Proceed with your evil plan, sumbitch." The initial smash on glance. The, the drawing near. This takes a long time, it seems like months, although only minutes pass, in fact. Languor is the word that describes this part of the process. Your persona floats toward her persona, over the Sea of Hesitation. Many weeks pass before they meet, but the weeks are days, or seconds. Still, everything is decided. You have slept together in the glance.
