I Silmarillion talar Eru själv om det, när han berättar för Ulmo att det inte skulle vara så mycket skönhet utan Melkor meddling.
And Ilúvatar spoke to Ulmo, and said: ‘Seest thou not how here in this little realm in the Deeps of Time Melkor hath made war upon thy province? He hath bethought him of bitter cold immoderate, and yet hath not destroyed the beauty of thy fountains, nor of thy clear pools. Behold the snow, and the cunning work of frost! Melkor hath devised heats and fire without restraint, and hath not dried up thy desire nor utterly quelled the music of the sea. Behold rather the height and glory of the clouds, and the everchanging mists; and listen to the fall of rain upon the Earth! And in these clouds thou art drawn nearer to Manwë, thy friend, whom thou lovest.’ - AINULINDALË
Det är det onda och det ledsen som skapar den verkliga skönheten i ordet.
