With the growth of knowledge our ideas must from time to time be organized afresh. The change takes place usually in accordance with new maxims as they arise, but it always remains provisional.
Johann Wolfgang von GoetheHe who does not know foreign languages does not know anything about his own.
Johann Wolfgang von GoetheWhen I consider the narrow limits within which our active and inquiring faculties are confined; when I see how all our energies are wasted in providing for mere necessities, which again have no further end than to prolong a wretched existence; and then that all our satisfaction concerning certain subjects of investigation ends in nothing better than a passive resignation... when I consider all this... I am silent.
Johann Wolfgang von Goethe
