It is a great and beautiful spectacle to see a man somehow emerging from oblivion by his own efforts, dispelling with the light of his reason the shadows in which nature had enveloped him, rising above himself, soaring in his mind right up to the celestial regions, moving, like the sun, with giant strides through the vast extent of the universe, and, what is even greater and more difficult , returning to himself in order to study man there and learn of his nature, his obligations , and his end. Jean - Jacques Rousseau Political philosopher
