orcs and trolls

[Orald]

From Letter 153:

I think I agree about the 'creation by evil'. But you are more free with the word 'creation' than I am. Treebeard does not say that the Dark Lord 'created' Trolls and Orcs. He says he 'made' them in counterfeit of certain creatures pre-existing. There is, to me, a wide gulf between the two statements, so wide that Treebeard's statement could (in my world) have possibly been true. It is not true actually of the Orcs – who are fundamentally a race of 'rational incarnate' creatures, though horribly corrupted, if no more so than many Men to be met today. Treebeard is a character in my story, not me; and though he has a great memory and some earthy wisdom, he is not one of the Wise, and there is quite a lot he does not know or understand. He does not know what 'wizards' are, or whence they came (though I do, even if exercising my subcreator's right I have thought it best in this Tale to leave the question a 'mystery', not without pointers to the solution).
