"All thinking must renounce the attempt to explain the universe. We cannot understand what happens in the universe. What is glorious in it is united with what is full of horror. What is full of meaning is united to what is senseless. The spirit of the universe is at once creative and destructive-- it creates while it destroys and destroys while it creates, and therefore it remains to us a riddle. And we must inevitably resign ourselves to this." --Albert Schweitzer
