I’m having trouble with your handwriting, which I have to read backwards. If you’re talking about the philosopher Levinas you’re talking about ethics, but not necessarily ethics the way other philosophers talk about it. Bernasconi in the Routledge Encyclopedia of Philosophy has a good description of his major works and how the Other has claims on the Self which are impossible to meet. The bibliography has some suggested reading which looks promising. Let me know if you’d like more, or if I’m totally misreading your question. bit.ly/bc-levinas
