In this essay, I shall describe both Plato and Levinas as philosophers of the other, and delineate their similarities and differences on violence. In doing so, I will open up for broader reflection two importantly contrasting ways in which the self is essentially responsive to-as well as vulnerable to violence from-the other. I will also suggest a new way of situating Levinas in the history of philosophy, not, as he himself suggests, as one of the few in the history of philosophy who has a philosophy of the other but, instead, as one of a number of 20th century philosophers who turn to pre-modern thinkers for aid in critiquing early modern thought on a variety of topics, including whether the self is essentially closed or, instead, vulnerable, open and responsive to what is outside it.
