The Rectitude of Inclination

THE RECTITUDE OF INCLINATION NICHOLAS INGHAM, 0.P. Provincial Archives Providence, Rhode Island 0 F THE MOST plausible mainline treatments of the relation of inclination to action and of their combination to moral estimation-Kantian, Classical Utilitarian, and Aristotelian-Thomist--only the third, remarkably enough, provides for the possibility of intrinsic rectitude as regards inclination . For Kant, of course, inclination is not only indifferent to morality but censurable as a criterion for action; indeed, any act done from inclination is, for Kant, pre-moral at best and immoral at worst. Classical Utilitarianism would appear to hold that the desire for pleasure, since it is correct by nature, must also be indefectibly and intrinsically correct. But this is not so, since in any choice situation an inclination toward a given pleasure , right by nature, may be counterbalanced by competing claims, whether these claims themselves arise from other inclinations within the one moral subject or from distinct subjects with differing claims. Hence, Classical Utilitarianism must accept a doctrine of extrinsic correctness as regards the evaluation of any inclination unless the version in question can establish a universally valid overriding principle of right-in which case it is Utilitarianism no longer but some form of deontological ethics. Only in the moral thought of Aristotle and Aquinas do we actually find a plausible case for the rectitude of inclination. And it is therefore surprising that so little attention has been paid this and that so many doctrinal Aristotelian-Thomists seem unaware of it. For many scholars, otherwise well acquainted with the basic philosophical views defended by St. Thomas Aquinas in his 417 418 NICHOLAS INGHAM, O.P. Aristotelian commentaries, remain surprisingly unfamiliar with one of the most interesting parts of his metaphysics of morals: right appetite, inclination, or emotion as an integral part of moral science, moral activity, and reflexive knowledge of the morality of conduct and of disposition.' I should like to set out what seem to me to be the general Aristotelian-Thomist views, as expressed in the commentary on the Nicomachean Ethics, and to develop from them a full account of intrinsic, extrinsic, stable, and per se rectitude as regards inclination or appetite. The first step in this development requires us to consider whether a moral science is possible and, if so, of what kind it must be. I Initially both St. Thomas and Aristotle appear to neglect altogether the problem whether there can be moral science as such. In listing the five intellectual virtues (understanding, science, wisdom, prudence, and art) neither mentions a science of right action. Would such a discipline be theoretical? Ordinarily the theoretical sciences in Aristotle and Aquinas perfect only theoretical powers. Does right action fall only under prudence? Prudence ordinarily is taken to be a practical virtue, not one specifically pertaining to the sciences. Three solutions to the difficulty offer themselves at once: first, moral science belongs essentially among ·the theoretical disciplines , even where allowance is made for the inclusion of practical elements in some methodologically defensible way; second, it is science but only in a highly derivative and improper sense and, in fact, is more correctly treated as providing something like a schema for the exercise of the cardinal virtues, especially prudence; third, it is thoroughly scientific in the strict and unqualified sense of the term, yet essentially not a theoretical but a practical discipline. 1 It is surprising how little serious attention seems to have been paid to Aristotle's remark in Ethics VII, 3, 1147a26-28, that, while the immediate conclusion of theoretical reasoning is affirmation, the immediate result of practical reasoning is action. THE RECTITUDE OF INCLINATION 419 The first solution, as one might easily imagine, has been championed by many of the most illustrious commentators. John of St. Thomas appears to hold that moral science is, as such, purely theoretical, even though it has practical application in prudential application.2 Maritain seems to believe that it is the theoretical treatment of a subject matter intrinsically practical in nature.3 Lottin holds that it is speculatively practical-a mixture 2 "Scientia moralis potest dupliciter considerari; uno modo, ut etiam includit prudentiam , alio modo, ut earn excludit et solum versatur circa cognitionem virtutum...
