Moral Science; a Compendium of Ethics

by Alexander Bain

The ethical writings of Kant, in the order of their appearance, are—Foundation for the Metaphysic of Morals (1785); Critique of the Practical Reason (1788); Metaphysic of Morals (1797, in two parts—(1) Doctrine of Right or Jurisprudence, (2) Doctrine of Virtue or Ethics proper). The third work contains the details of his system; the general theory is presented in the two others. Of these we select for analysis the earlier, containing, as it does, in less artificial form, an ampler discussion of the fundamental questions of morals; but towards the end it must be supplemented, in regard to certain characteristic doctrines, from the second, in some respects more developed, work.[26]

In the introduction to the Metaphysic of Morals, Kant distinguishes between the empirical and the rational mode of treating Ethics. He announces his intention to depart from the common plan of mixing up the two together, and to attempt for once to set forth the pure moral philosophy that is implied even in the vulgar ideas of duty and moral law. Because a moral law means an absolute necessity laid on all rational beings whatever, its foundation is to be sought, not in human nature or circumstances, but à priori in the conception of pure reason. The most universal precept founded on mere experience is only a practical rule, and never a moral law. A purely rational moral philosophy, or Metaphysic of Morals, will serve the double end of meeting a speculative requirement, and of furnishing the only true norm of practice. It investigates the idea and principles of a potentially pure Will, instead of the acts and conditions of human volition as known from psychology. Not a complete Metaphysic of Morals, however, (which would be a Critique of the pure Practical Reason), but merely a foundation for such will be given. The supreme principle of morality is to be established, apart from detailed application. First, common notions will be analyzed in order to get at this highest principle; and then, when the principle has been sought out, they will be returned upon by way of synthesis.

In the first of the three main sections of the work, he makes the passage from Common Rational Knowledge of Morals to Philosophical. Nothing in the world, he begins, can without qualification be called good, except Will. Qualities of temperament, like courage, &c., gifts of fortune, like wealth and power, are good only with reference to a good will. As to a good will, when it is really such, the circumstance that it can, or cannot, be executed does not matter; its value is independent of the utility or fruitlessness of it.

This idea of the absolute worth of mere Will, though it is allowed even by the vulgar understanding, he seeks to establish beyond dispute, by an argument from the natural subjection of Will to Reason. In a being well-organized, if Conservation or Happiness were the grand aim, such subjection would be a great mistake. When Instinct could do the work far better and more surely, Reason should have been deprived of all practical function. Discontent, in fact, rather than happiness comes of pursuit of mere enjoyment by rational calculation; and to make light of the part contributed by Reason to happiness, is really to make out that it exists for a nobler purpose. But now, since Reason is a practical faculty and governs the will, its function can only be to produce a Will good in itself. Such a Will, if not the only good, is certainly the highest; and happiness, unattainable by Reason as a primary aim, and subject in this life altogether to much limitation, is to be sought only in the contentment that arises from the attainment by Reason of its true aim, at the sacrifice often of many a natural inclination.

He proceeds to develop this conception of a Will in itself good and estimable, by dealing with the commonly received ideas of Duty. Leaving aside profitable actions that are plain violations of duty, and also actions conformed to duty, but, while not prompted directly by nature, done from some special inclination—in which case it is easy to distinguish whether the action is done from duty or from self-interest; he considers those more difficult cases where the same action is at once duty, and prompted by direct natural inclination. In all such, whether it be duty of self-preservation, of benevolence, of securing one's own happiness (this last a duty, because discontent and the pressure of care may easily lead to the transgression of other duties), he lays it down that the action is not allowed to have true moral value, unless done in the abeyance or absence of the natural inclination prompting to it. A second position is, that the moral value of an action done from duty lies not in the intention of it, but in the maxim that determines it; not in the object, but in the principle of Volition. That is to say, in action done out of regard to duty, the will must be determined by its formal à priori principle, not being determined by any material à posteriori motive. A third position follows then from the other two; Duty is the necessity of an action out of respect for Law. Towards an object there may be inclination, and this inclination may be matter for approval or liking; but it is Law only—the ground and not the effect of Volition, bearing down inclination rather than serving it—that can inspire Respect. When inclination and motives are both excluded, nothing remains to determine Will, except Law objectively; and, subjectively, pure respect for a law of practice—i.e., the maxim to follow such a law, even at the sacrifice of every inclination. The conception of Law-in-itself alone determining the will, is, then, the surpassing good that is called moral, which exists already in a man before his action has any result. Conformity to Law in general, all special motive to follow any single law being excluded, remains as the one principle of Volition: I am never to act otherwise, than so as to be able also to wish that my maxim (i.e., my subjective principle of volition) should become a universal law. This is what he finds implied in the common notions of Duty.

Having illustrated at length this reading, in regard to the duty of keeping a promise, he contrasts, at the close of the section, the all but infallibility of common human reason in practice with its helplessness in speculation. Notwithstanding, it finds itself unable to settle the contending claims of Reason and Inclination, and so is driven to devise a practical philosophy, owing to the rise of a 'Natural Dialectic' or tendency to refine upon the strict laws of duty in order to make them more pleasant. But, as in the speculative region, the Dialectic cannot be properly got rid of without a complete Critique of Reason.

In Section II. the passage is made from the popular moral philosophy thus arising to the metaphysic of morals. He denies that the notion of duty that has been taken above from common sage is empirical. It is proved not to be such from the very assertions of philosophers that men always act from more or less refined self-love; assertions that are founded upon the difficulty of proving that acts most apparently conformed to duty are really such. The fact is, no act can be proved by experience to be absolutely moral, i.e., done solely from regard to duty, to the exclusion of all inclination; and therefore to concede that morality and duty are ideas to be had from experience, is the surest way to get rid of them altogether. Duty, and respect for its law, are not to be preserved at all, unless Reason is allowed to lay absolute injunctions on the will, whatever experience says of their non-execution. How, indeed, is experience to disclose a moral law, that, in applying to all rational beings as well as men, and to men only as rational, must originate à priori in pure (practical) Reason? Instead of yielding the principles of morality, empirical examples of moral conduct have rather to be judged by these.

All supreme principles of morality, that are genuine, must rest on pure Reason solely; and the mistake of the popular practical philosophies in vogue, one and all—whether advancing as their principle a special determination of human nature, or Perfection, or Happiness, or Moral Feeling, or Fear of God, or a little of this and a little of that—is that there has been no previous consideration whether the principles of morality are to be sought for in our empirical knowledge of human nature at all. Such consideration would have shown them to be altogether à priori, and would have appeared as a pure practical philosophy or metaphysic of morals (upon the completion of which any popularizing might have waited), kept free from admixture of Anthropology, Theology, Physics, Hyperphysics, &c., and setting forth the conception of Duty as purely rational, without the confusion of empirical motives. To a metaphysic of this kind, Kant is now to ascend from the popular philosophy, with its stock-in-trade of single instances, following out the practical faculty of Reason from the general rules determining it, to the point where the conception of Duty emerges.

While things in nature work according to laws, rational beings alone can act according to a conceived idea of laws, i.e., to principles. This is to have a Will, or, what is the same, Practical Reason, reason being required in deducing actions from laws. If the Will follows Reason exactly and without fail, actions objectively necessary are necessary also subjectively; if, through subjective conditions (inclinations, &c.), the Will does not follow Reason inevitably, objectively necessary actions become subjectively contingent, and towards the objective laws the attitude of the will is no longer unfailing choice, but constraint. A constraining objective principle mentally represented, is a command; its formula is called Imperative, for which the expression is Ought. A will perfectly good—i.e., subjectively determined to follow the objective laws of good as soon as conceived—knows no Ought. Imperatives are only for an imperfect, such as is the human, will. Hypothetical Imperatives represent the practical necessity of an action as a means to an end, being problematical or assertory principles, according as the end is possible or real. Categorical Imperatives represent an action as objectively necessary for itself, and count as apodeictical principles.

To the endless number of possible aims of human action correspond as many Imperatives, directing merely how they are to be attained, without any question of their value; these are Imperatives of Fitness. To one real aim, existing necessarily for all rational beings, viz., Happiness, corresponds the Imperative of Prudence (in the narrow sense), being assertory while hypothetical. The categorical Imperative, enjoining a mode of action for itself, and concerned about the form and principle of it, not its nature and result, is the Imperative of Morality. These various kinds of Imperatives, as influencing the will, may be distinguished as Rules (of fitness), Counsels (of prudence), Commands or Laws (of morality); also as technical, pragmatical, moral.
