Rob and Massimo interview Liz Gloyn, author of The Ethics of the Family in Seneca. We talk about the radical approach of the Stoics to human relationships, the concepts of oikeiosis (appropriation of other people's concerns) and cosmopolitanism, and why Seneca was a far more innovative thinker than he is often given credit for.
