How Lust Works

Author's Note

Since lust gets such a bad rap, I was pleased to have the chance to offer some scientific evidence to help burnish its Sodom and Gomorrah reputation. Although the motivational drive of lust has a tendency to get people in trouble at times, it's nevertheless crucial to the sweeter romantic sentiments that human culture holds so dear. Moreover, the principles of morality, yet another cultural byproduct, have glossed over the brighter sides of lust for centuries, and only in recent decades has factual understanding of brain-body connections illuminated the practical purposes and mechanisms of sex drives. But most importantly, grasping how lust works better allows us answer the all-important question: When do you know when it's love?
