Resignation as to knowledge of the world is for me not an irretrievable plunge into a scepticism which leaves us to drift about in life like a derelict vessel. I see in it that effort of honesty which we must venture to make in order to arrive at the serviceable world-view which hovers within sight. Every world-view which fails to start from resignation in regard to knowledge is artificial and a mere fabrication, for it rests upon an inadmissible interpretation of the universe.
