Hermann Poppelbaum said this quote

“ ...the great experiences which form him, arise out of the discontinuity and disharmony between man and the world. Particularly in great personalities, we see how much of their beauty and excellence is really due to trials suffered earlier at the hands of the world. Beauty--as many have recognized--is pain suffered and transformed. Because the animal is adapted to its environment, it is denied the possibility of developing inward maturity and greatness. As an individual creature it cannot grow beyond the limits of its kind; and again, at death, it falls back with its capacities into the group Ego, from which its soul was something like an offshoot or a patrol sent out on reconnaissance. ”
