§ Of Aulë and Yavanna The Silmarillion

But Aulë answered: 'That shall also be true of the Children of Ilúvatar; for they will eat and they will build. And though the things of thy realm have worth in themselves, and would have worth if no Children were to come, yet Eru will give them dominion, and they shall use all that they find in Arda: though not, by the purpose of Eru, without respect or without gratitude.'
