War must be, while we defend our lives against a destroyer who would devour all; but I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend: the city of the Men of Númenor; and I would have her loved for her memory, her ancientry, her beauty, and her present wisdom.
