My argument against God was that the universe seemed so cruel and unjust. But how had I got this idea of just and unjust? A man does not call a line crooked unless he has some idea of a straight line . . . Thus, in the very act of trying to prove that God did not exist in other words, that the whole of reality was senseless I found I was forced to assume that one part of reality namely my idea of justice was full of sense.
