Historical refutation as the definitive refutation.- In former times, one sought to prove that there is no God - today one indicates how the belief that there is a God arose and how this belief acquired its weight and importance: a counter-proof that there is no God thereby becomes superfluous.- When in former times one had refuted the 'proofs of the existence of God' put forward, there always remained the doubt whether better proofs might not be adduced than those just refuted: in those days atheists did not know how to make a clean sweep.
