Levinas and Adorno on the inhuman dimension

The relation between Emmanuel Levinas and Theodor W. Adorno centers on a problem their ethics and social criticism both expose but do not, in the account presented here, fully resolve: whether the inhuman is merely a violence to be opposed or also an opaque limit that makes any definition of the human possible. Levinas foregrounds responsibility to the other, while Adorno exposes the violence hidden in claims to define humanity. The proposed difficulty lies beneath both positions: human beings are not made human by achieving complete autonomy or fitting into a universal account, but neither is every form of imposed vulnerability ethically acceptable.

Shared Critique of the Human

Emmanuel Levinas’s limitation is not described simply as Eurocentrism, even though a narrow account of humanity can quietly exclude non-Europeans from full recognition. The deeper omission is the inhuman dimension itself: what cannot be gathered into a face-to-face relation between people. Ethical attention to another person’s face does not, by itself, account for an otherness that resists recognition and inclusion in a human narrative.

Theodor W. Adorno is more alert to how prevailing definitions of the human exert violence by excluding whole dimensions as nonhuman. Yet his account tends to treat the inhuman as alienated humanity, or as barbarism that must be fought. The criticism is not that Adorno fails to condemn barbarism. It is that this opposition still leaves the inhuman outside the positive account of what being human is.

The difficulty is therefore shared but not identical. Levinas’s ethical encounter risks leaving out what cannot enter the face-to-face relation; Adorno recognizes exclusion but tends to understand what is excluded as something to overcome. Against both tendencies, the argument identifies an impenetrable ground of inhumanity: a remainder that resists being incorporated into any complete account of the human. Such opacity is not simply an accidental defect in a definition. It is the condition against which any normative definition takes shape.

Finitude and Enlightenment’s Contradiction

Adorno’s account of the Enlightenment makes the problem especially sharp. With Max Horkheimer, he treats the catastrophes and barbarisms of the twentieth century as consequences internal to the Enlightenment project, rather than as leftover barbarism that a completed Enlightenment could simply abolish. Yet the response is still to fight those consequences by means of Enlightenment itself. The critical project thus relies on the very tradition whose excesses it diagnoses.

That contradiction raises two possibilities. One is to supply a positive normative framework capable of guiding criticism. The other, associated here with Jacques Lacan, is to redefine humanity through the limitation that universal ideals tend to conceal. On this second route, being human involves finitude, passivity, and vulnerable exposure, rather than an ideal of an unlimited, self-sufficient subject. The issue is not whether Enlightenment should be abandoned, but whether its limits can be understood as internal to its meaning rather than treated as an obstacle that further progress will remove.

This distinction also prevents a simple equation between vulnerability and violence. Situations in which an external force violates or thwarts someone’s will should be condemned as inhuman. But it does not follow that humanity is therefore identical with autonomy of will. A certain passive exposure to overwhelming otherness may itself be constitutive of being human. The account leaves the distinction difficult: it insists on opposing coercive violence while refusing to make invulnerable self-determination the measure of human worth.

The Muselmann as a Limit Case

The Muselmann in the concentration camps gives this problem its starkest formulation. The figure represents a human being reduced to inhumanity, an otherness that cannot be assimilated to the familiar ethical encounter with another person. The example is not offered as a positive ideal of passivity, nor as a reason to accept the violence that produces such reduction. It marks the point at which a confident definition of humanity, whether grounded in autonomous will or in a recognizable face, fails to contain what has happened.

This limit also bears on how ethical reflection approaches catastrophe. The discussion challenges the assumption that a general language of responsibility necessarily reproduces the thought of those who experienced the ethical abyss at first hand. In its account, the emphasis on questioning one’s own right to exist and accepting unconditional responsibility is characteristic of people observing catastrophe from a minimal distance and feeling guilty about that distance; it is not how a survivor thinks and writes. The contrast does not dismiss ethical responsibility. It warns that a philosophical description of responsibility may reveal the position of its speaker as much as it describes the experience of its subject.

The Unresolved Ethical Stakes

The relation between Levinas and Adorno is consequently organized around a tension rather than a settled synthesis. Levinas’s attention to the other cannot encompass every form of otherness; Adorno’s critique of exclusion does not fully establish how the inhuman can be constitutive of being human without being confused with the barbarism that must be resisted. Their shared challenge to a complete, self-authorizing human subject remains essential, but it does not by itself distinguish imposed dehumanization from the vulnerable exposure that the argument treats as part of human existence.

The resulting account refuses two easy conclusions: that humanity can be secured by autonomy alone, or that whatever lies beyond autonomy should be accepted as ethically meaningful. Instead, it holds together a demand to condemn violence and a recognition that human life is finite, exposed, and not fully captured by normative definitions. The unresolved gap between those claims is not a side issue in the comparison. It is the point at which its account of the human begins.
