...Beauty is a terrible and awful thing! It is terrible because it never has and never can be fathomed, for God sets us nothing but riddles. Within beauty both shores meet and all contradictions exist side by side. I'm not a cultivated man, brother, but I've thought a lot about this. Truly there are mysteries without end! Too many riddles weigh man down on earth. We guess them as we can, and come out of the water dry. Beauty! I cannot bear the thought that a man of noble heart and lofty mind sets out with the ideal of the Madonna and ends with the ideal of Sodom. What's still more awful is that the man with the ideal of Sodom in his soul does not renounce the ideal of the Madonna, and in the bottom of his heart he may still be on fire, sincerely on fire, with longing for the beautiful ideal, just as in the days of his youthful innocence. Yes, man's heart is wide, too wide indeed. I'd have it narrower. The devil only knows what to make of it! but what the intellect regards as shameful often appears splendidly beautiful to the heart. Is there beauty in Sodom? Believe me, most men find their beauty in Sodom. Did you know this secret? The dreadful thing is that beauty is not only terrifying but also mysterious. God and the Devil are fighting there, and their battlefield is the heart of man. But a man's heart wants to speak only of its own ache. Listen, now I'll tell you what it says....
