Ethics Before Ontology

Western philosophy has almost always started with ontology: the study of being, of what exists and how. From Aristotle's first philosophy to Heidegger's fundamental ontology, the question "what is?" precedes the question "what should I do?" Ethics, on this picture, is something you arrive at after settling the metaphysical furniture. You understand the nature of persons, of rationality, of the good, and then you derive moral obligations.

Emmanuel Levinas (1906–1995), Lithuanian-born, educated in the phenomenological tradition of Husserl and Heidegger, and a survivor of Nazi imprisonment, reversed this priority with a force that was both philosophical and deeply personal. For Levinas, ethics is first philosophy: not derived from ontology but prior to it, the very structure within which any encounter with being takes place. And the core of ethics is not a principle, a calculation, or a law, it is a relation: the face-to-face encounter with another person.

Levinas's critique of the Western tradition is sweeping. He argues that philosophy from the Greeks onward has been dominated by what he calls the philosophy of the Same: the drive to reduce everything encountered, including other people, to something the I can comprehend, categorize, and contain within its own conceptual system. When you encounter a stranger and immediately classify them by role, nationality, function, or type, you are performing this reduction: you are making the Other manageable by assimilating them to concepts you already possess. You replace the irreducible person with a representation.

Heidegger, his own teacher, is the sharpest target. Heidegger's Being and Time gives an account of Dasein's world-involving existence in which other people primarily appear as equipment-like, as the anonymous "they" of everyday life, or as co-workers in shared projects. Even Heidegger's analysis of authentic existence centers on the individual's own being-toward-death. For Levinas, Heidegger's entire edifice, despite its sophistication, remains a philosophy of the Same: Being is still the horizon that absorbs everything, including the Other person.

The way in which the other presents himself, exceeding the idea of the other in me, we here name face. [...] The face of the Other at each moment destroys and overflows the plastic image it leaves me, the idea existing to my own measure. [...] It expresses itself.

— Emmanuel Levinas, Totality and Infinity (1961), trans. Alphonso Lingis

The face (le visage) is Levinas's name for the Other's mode of self-presentation that cannot be reduced to any representation. It is not literally the physiognomy, the nose, eyes, and mouth. It is the nakedness and vulnerability of the Other's presence: the fact that this person stands before you undefended, exposed, making an appeal that precedes any words. "Naked and defenseless, the face signifies, with or without words, 'Do not kill me.'" It confronts you as a prohibition before it confronts you as a theme for thought.

This is the central move of Totality and Infinity (1961): the Other's face breaks open the closed world of the I's self-sufficiency. The I, left to itself, would be a self-enclosing economy, going out into the world and returning enriched, everything feeding back into the same. The Other's face interrupts this circuit. It introduces infinity, something that genuinely exceeds my capacity to contain, comprehend, or master, into the finite world of the subject.
