Immanuel Kant is a profoundly influential figure in modern philosophy, and was one of the earliest proponents for universal democracy and international cooperation. He also thought that women have no place in civil society, that it was okay to kill illegitimate children, and that there was a ranking in the moral worth of different races.

Throughout history we’ve consistently believed, as common sense, truly horrifying things by today’s standards. According to University of Oxford Professor Will MacAskill, it’s extremely likely that we’re in the same boat today. If we accept that we’re probably making major moral errors, how should we proceed?

In this conversation from 2018, Will makes the case that we need to develop a moral view that criticises common sense intuitions, and gives us a chance to move beyond them.
