Kantian tolerance and Levinasian exposure are both immunologically structured

Evidence

Thus, Kant’s moral subject practices tolerance, which represents a genuinely immunological category. That is, tolerance concerns Otherness. Kant’s ethics is an ethics of negativity, which Hegel leads to completion with his theory of recognition. Levinas, on the other hand, reduces immunological tolerance to absolute zero. Thus, the ego stands “exposed” to the “violence” that comes from the Other and puts it into question radically. The emphasis on the wholly Other lends Levinas’s ethics an immunological character. — Byung-Chul Han, The Burnout Society, 164
