"As we have seen, Heidegger secularizes the Single One of Kierkegaard, that is, he severs the relation to the absolute for which Kierkegaard’s man becomes a Single One. And as we have seen, he does not replace this “for” with any other worldly and human “for”. He ignores the decisive fact that only the man who has become a Single One, a self, a real person, is able to have a complete relation of his life to the other self, a relation which is not beneath but above the problematic of the relations between man and man, and which comprises, withstands and overcomes all this problematic situation."
