Byung-Chul Han

The positivation of the world allows new forms of violence to emerge. They do not stem from the immunologically Other. Rather, they are immanent in the system itself. Because of this immanence, they do not involve immune defense. Neuronal violence leading to psychic infarctions is a terror of immanence. It differs radically from horror that emanates from the foreign in the immunological sense. Medusa is surely the immunological Other in its extreme form. She stands for radical alterity that one cannot behold without perishing in the process. Neuronal violence, on the other hand, escapes all immunological optics, for it possesses  no negativity. The violence of positivity does not deprive, it saturates; it does not exclude, it exhausts. That is why it proves inaccessible to unmediated perception.
