Guests:  Agnes Callard is an associate professor of philosophy at the University of Chicago and a columnist at The Point. Myisha Cherry is an assistant professor of philosophy at the University of California, Riverside. This episode was produced in partnership with Boston Review. Learn more about your ad choices.
