Goethe did not take such a step easily, for it was one of his scientific principles never to think out an idea prematurely. He was well aware that he who aspires to recognize and to express in idea the spirit which reveals itself through the phenomena of the sense-world must develop the art of waiting - of waiting, however, in a way intensely active, whereby one looks again and yet again, until what one looks at begins to speak and the day at last dawns when, through tireless 're-creation of an ever-creating nature', one has grown ripe to express her secrets openly. Goethe was a master in this art of active waiting.
