 Experimental philosophers can agree with this objection, up to a point. No one is suggesting that we read morality directly off survey results. But, to return to the point with which we began, while morality is normative, it is also essentially practical. Moral theory is a theory about what we ought to do: a theory about how creatures like us ought to conduct ourselves and interact with one another. A morality completely divorced from our natures, that demanded acts impossible from us, would surely be unacceptable. This is not just a point about experimental philosophy; utilitarianism is sometimes critiqued as making unrealistic demands of impartiality. Alongside the famous proscription against deriving an ought from an is, we also find the dictum that ought implies can. The exact extent to which morality can be demanding without being unrealistic is itself a philosophical question, and so experimental moral philosophy works in conjunction with philosophical analysis; it does not aim to eliminate it. Exactly how the two relate to each other, and how empirical evidence will bear on and influence debates in moral theory in the future, is a contested issue, but surely traditional moral theory and experimental moral philosophy have much to learn from one another (Doris, Machery &amp; Stich 2017).
