In Humanism of the Other, Emmanuel Levinas argues that it is not only possible but of the highest exigency to understand one's humanity through the humanity of others. Based in a new appreciation for ethics, and taking new distances from the phenomenology of Hegel, Heidegger, Husserl, and Merleau-Ponty, the idealism of Plato and Kant, and the skepticism of Nietzsche and Blanchot, Levinas rehabilitates humanism and restores its promises. 

He expresses disappointment with the revolutions that became bureaucracies and totalitarian governments, and the national liberation movements that eventually led to oppression and international wars. Defining the human as subject, ego, synthesis, ... Read moreidentification, cognition, and mood all too easily lead to subjugation, persecution, and murder. 

Painfully aware of the long history of dehumanization which reached its apotheosis in Hitler and Nazism, Levinas does not underestimate the difficulty of reconciling oneself with another. The humanity of the human, Levinas argues, is not discoverable through mathematics, rational metaphysics or introspection. Rather, it is found in the recognition that the suffering and mortality of others are the obligations and morality of the self.
