"Whence do I come and whence comes the world in which and by which I live? Whither do I go and whither goes everything that environs me? What does it all mean? Such are the questions that man asks as soon as he frees himself from the brutalizing necessity of laboring for his material sustenance. And if we look closely, we shall see that beneath these questions lies the wish to know not so much the 'why' as the 'wheretofore,' not the cause but the end."
