 A second question—call it the evaluation question—concerns morality: How should we evaluate the moral status of manipulation? A satisfactory answer to this question should tell us whether manipulation is always immoral. And if manipulation is not always immoral, it should tell us how to determine when manipulation is immoral. But more importantly, a satisfactory answer to the evaluation question should explain why manipulation is immoral when it is immoral. What feature of manipulation makes it immoral in those situations when it is immoral?
