Today, we discuss separately on the ethics of the dual (typically Levinasian ethics) and on the ethics of the multiplicity (contemporary ethics since Kant). But can we discuss on the contemporary ethics without reference to the ethics of the dual? Can it treat the other essentially? It seems that Hannah Arendt answers these questions in her way. We should be discreet in treating the other in a universal manner. The ethics of the dual is superior to the ethics of the multiplicity, and the latter cannot be justified only if it is based on the former.
