"We have to know cognitively what another mind is thinking and also empathically what they're feeling. And of course, in general, that's always the case, but it's often very generic. Like with Leo Cullum's doctor, it's just the fact that people in general are cruel and insensitive. But in the Barbara Smaller cartoon, we understand it's this particular person or this specific sub-class of person and her particular needs and desires, and that's different than a pun cartoon in which it's just semantic."
