"Our sex organs were kind of like hands or feet, they were obedient," says Eric Berkowitz, author of Sex and Punishment: Four Thousand Years of Judging Desire. "After we ate the apple and did what we did, the sex organs to Augustine became like little dictators that we have to either succumb to or overpower."

ReasonTV's Tracy Oppenheimer sat down with Berkowitz to discuss original sin, trends in sex laws, and societies' perceptions of sexual transgressions.
