It's rather obvious that it's JRR Tolkien speaking, since he's actually saying he's talking about the Lord of the Rings:
"Nothing that happens to Man is natural, since his presence calls the whole world into question. All men must die; but for each man, his death is an accident, and and even if he knows it, an unjustifiable violation". Now, you may agree with those words or not: but they are the keyspring of The Lord of the Rings'."
