Man is not by any means of fixed and enduring form (this, in spite of suspicions to the contrary on the part of their wise men, was the ideal of the ancients). He is nothing else than the narrow and perilous bridge between nature and spirit. His innermost destiny drives him on to the spirit and to God. His innermost longing draws him back to nature, the mother. Between the two forces his life hangs tremulous and irresolute.
