Everyone is the other, and no one is himself. The they, which supplies the answer to the who of everyday Da-sein, is the nobody to whom every Da-sein… - Martin Heidegger

Do the essences of proposition and of the truth determine themselves from out of the essence of the thing, or does the essence of the thing determine itself from out of the essence of the proposition? The question is posed as an either/or. However does this either/or itself suffice? Are the essence of the thing and the essence of the proposition only built as mirror images because both of them together determine themselves from out of the same but deeper lying root? However, what and where can be this common ground for the essence of the thing and of the proposition and of their origin? The unconditioned (Unbedingt)? We stated at the beginning that what conditions the essense of the thing in its thingness can no longer itself be thing and conditioned, it must be an unconditioned (Un-bedingtes). p. 47
