There is nothing in the world more pitiable than an irresolute man, oscillating between two feelings, who would willingly unite the two and who does not perceive that nothing can unite them
Johann Wolfgang von GoetheWithout my attempts in natural science, I should never have learned to know mankind such as it is. In nothing else can we so closely approach pure contemplation and thought, so closely observe the errors of the senses and of the understanding, the weak and strong points of character.
Johann Wolfgang von Goethe
