Statements about a person's good slip into and out of our ordinary discourse about the world with nary a ripple. Such statements are objects of belief and assertion, they obey the rules of logic, and they are often defended by evidence and argument. They even participate in common-sense explanations, as when we say of some person that he has been less subject to wild swings of enthusiasm and disappointment now that, with experience, he has gained a clearer idea of what is good for him. Statements about a person's good present themselves as being about something with respect to which our beliefs can be true or false, warranted or unwarranted. Let us speak of these features as the descriptive side of discourse about a person's good

Traditional virtue-oriented approaches to ethics suppose that acquiring relatively stable character traits, such as courage and compassion, is crucial in addressing the question of how to be. However, recent psychological studies cast doubt on the idea that people develop such traits. In light of this pessimism, the paper raises the question: what is left of virtue theory? It argues that much remains once one shifts from a traditional understanding of virtues to one of cognitive/affective “if…then” dispositions that form a person’s character. The central proposal is to understand such dispositions as “habitudes” – habitual ways of thinking, feeling, and acting that are acquired by example and repetition, and that enable one to competently react to varying situations one confronts. The resulting model of ethical comportment represents a psychologically realistic understanding of virtue. Furthermore, this account fits well with what we learn from the field of positive psychology about subjective well-being, thus helping to vindicate eudaimonism.

Nous pouvons tous, je crois, reconnaître la justesse de la thèse d'Aristote à l'effet que le véritable raisonnement pratique a pour résultat non pas une simple croyance à propos du caractère désirable, ou même du caractère obligatoire, d'un acte, mais plutôt l'initiation effective d'une action. Cette thèse donne lieu à une énigme : comment la délibération, archétypiquement une inférence propositionnelle rationnelle , peut-elle logiquement aboutir à un acte ? L'action présuppose la motivation, mais la motivation est une force appétitive active, et non pas une proposition concernant le désir ou le caractère désirable d'un acte . La raison pratique n'est pas similaire aux substances qui peuvent manifestement être mélangées les unes aux autres, mais elle est censée constituer une fusion normative régie par des principes — le choix est un appétit délibéré , comme le dit Aristote. Comment ceci est-il possible ? Les premiers pas vers une réponse peuvent être trouvés à un endroit surprenant : chez Kant. Dans la Métaphysique des Moeurs , Kant présente une théorie du désir comme appétit pour un objet par le biais d'une idée non-sensorielle de cet objet, et ce, par opposition à une inclination , un appétit direct basé sur la sensation. Kant emploie cette notion du désir pour expliquer à la fois la volonté et la possibilité d'une action accomplie par devoir : la volonté appartient à la faculté de désirer, et le devoir est l'action motivée par un désir pour un acte par le biais d'une idée appropriée de cet acte. Kant nomme notre susceptibilité à ce type de désir laquelle constitue une condition nécessaire à la moralité le sentiment moral . Ce sentiment rend compte du caractère pratique de la délibération morale et de son rapport au plaisir et à la douleur pratiques d'une façon qui aurait, je crois, plu à Aristote. Le devoir est donc un exemple d'un appétit délibératif . Ce schème kantien n'est pas simplement intéressant d'un point de vue historique : il s'accorde remarquablement bien avec certains travaux récents en psychologie motivationnelle et hédonique.We all can, I think, appreciate the justness of Aristotle's view that genuine practical reasoning ends not in a mere belief about the desirability, or even obligatoriness, of an act, but in the actual initiation of action. This yields a puzzle: how can deliberation, archetypically a rational, propositional inference , logically terminate in an act? Action presupposes motivation, yet motivation is an active appetitive force, not a proposition about desire or desirability . Unlike substances can obviously be mixed together, but practical reason is supposed to a principled, normative fusing — choice is deliberated appetite , as Aristotle puts it. How is this possible? The beginnings of an answer can be found in a surprising place: Kant. In The Metaphysics of Morals Kant gives a theory of desire as appetite for an object through a non-sensory idea of it, in contrast to inclination , a sensation-based direct appetite. Kant uses this notion of desire to explain both will and the possibility of action from duty : will belongs to the faculty of desire, and duty is action motivated by a desire for an act through an appropriate idea. Kant terms our susceptibility to this sort of desire moral feeling , a necessary condition for morality. It accounts for the practicality of moral deliberation, and its linkage to practical pleasure and pain, in a way Aristotle would, I think, have found congenial. Duty, then, is an example of deliberated appetite . The Kantian scheme is not merely of historical interest: it fits surprisingly well with recent work in motivational and hedonic psychology.

An adequate theory of the nature of belief should help us explain the most obvious features of belief as we find it. Among these features are: guiding action and reasoning non-inferentially; varying in strength in ways that are spontaneously experience-sensitive; ‘aiming at truth’ in some sense and being evaluable in terms of correctness and warrant; possessing inertia across time and constancy across contexts; sustaining expectations in a manner mediated by propositional content; shaping the formation and execution of plans; generalizing spontaneously projectively; and being independent of the will and resisting instrumentalization. Using the method of ‘creature construction’, I attempt to show how we can build an attitude with these features step-by-step from simpler components, thereby avoiding the problems of regress or circularity affecting a number of influential accounts of belief.
