Disgust — an emotion that makes us human. It can keep us safe from drinking milk that's gone off, thanks to the revolting smell. And as Charles Darwin suggests, disgust serves as part of our core evolutionary function. But it also has a dark side. Disgust has been co-opted by culture, to religious and political divides. Scholars say we need to reckon with this complicated emotion that has the ability to make the world more dangerous.
