He who wishes to exert a useful influence must be careful to insult nothing. Let him not be troubled by what seems absurd, but concentrate his energies to the creation of what is good. He must not demolish, but build. He must raise temples where mankind may come and partake of the purest pleasure.
Johann Wolfgang von GoetheThe day is committed to error and floundering; success and achievement are matters of long range.
Johann Wolfgang von GoetheInsofar as he makes use of his healthy senses, man himself is the best and most exact scientific instrument possible. The greatest misfortune of modern physics is that its experiments have been set apart from man, as it were, physics refuses to recognize nature in anything not shown by artificial instruments, and even uses this as a measure of its accomplishments.
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
