“Historia in nuce [history in a nutshell]. Friend and Enemy. The friend is he who affirms and confirms me. The enemy is he who challenges me (Nuremberg 1947). Who can challenge me? Basically, only myself. The enemy is he who defines me. That means in concreto: only my brother can challenge me and only my brother can be my enemy.”– Carl Schmitt, while interned by American forces following World War II
