My modest aim in this piece is to frame and illuminate some of the issues surrounding normative motivation, rather than take a firm position on any of them. I begin by clarifying the key terms in my title of this essay, and unpacking some of the assumptions that underpin its question. I then distinguish four kinds of answers one might give. In this short essay I will not be able to properly develop and evaluate an argument for the view that (...) normative motivations are psychologically primitive, but I will have some comments about what such an argument might look like, and what it would have to show.

Thus declares Francis Hutcheson, expressing a view widespread during the Enlightenment, and throughout the history of philosophy. According to this tradition, we are by nature moral, and ourS concern for good and evil is as natural to us as our capacity to feel pleasure and pain. The link between morality and human nature has been a common theme since ancient times, and, with the rise of modern empirical moral psychology, it remains equally popular today. Evolutionary ethicists, ethologists, developmental psychologists, social (...) neuroscientists, and even some cultural anthropologists tend to agree that morality is part of the bioprogram (e.g., Cosmides & Tooby, 1992; de Waal, 1996; Haidt & Joseph, 2004; Hauser, 2006; Ruse, 1991; Sober & Wilson, 1998; Turiel, 2002). Recently, researchers have begun to look for moral modules in the brain, and they have been increasingly tempted to speculate about the moral acquisition device, and innate faculty for norm acquisition akin to celebrated language acquisition device, promulgated by Chomsky (Dwyer, 1999; Mikhail, 2000; Hauser, this volume). All this talk of modules and mechanism may make some shudder, especially if they recall that eugenics emerged out of an effort to find the biological sources of evil. Yet the tendency to postulate an innate moral faculty is almost irresistible. For one thing, it makes us appear nobler as a species, and for another, it offers an explanation of the fact that people in every corner of the globe seem to have moral rules. Moral nativism is, in this respect, an optimistic doctrine—one that makes our great big world seem comfortingly smaller. I want to combat this alluring idea. I do not deny that morality is ecumenical, but I think it is not innate—at least that the current state of evidence is unpersuasive. Morality, like all human capacities, depends on having particular biological predispositions, but none of these, I submit, deserves to be called a moral faculty. Morality is a byproduct—accidental or invented—of faculties that evolved for other purposes.. (shrink)

This paper considers the practical question of why people do not behave in the way they ought to behave. This question is a practical one, reaching both into the normative and descriptive domains of morality. That is, it concerns moral norms as well as empirical facts. We argue that two main problems usually keep us form acting and judging in a morally decent way: firstly, we make mistakes in moral reasoning. Secondly, even when we know how to act and judge, (...) we still fail to meet the requirements due to personal weaknesses. This discussion naturally leads us to another question: can we narrow the gap between what people are morally required to do and what they actually do? We discuss findings from neuroscience, economics, and psychology, considering how we might bring our moral behavior better in line with moral theory. Potentially fruitful means include nudging, training, pharmacological enhancement, and brain stimulation. We conclude by raising the question of whether such methods could and should be implemented.
