Conscience is not infallible in its application of the objective principle; a wider experience may show it to have erred. Conscience is highest authority, but still an authority which may continually perfect itself. The objective principle makes possible the mutual correction of different consciences and the self-correction of the conscience of the individual through self-judgment.
The difference between Subjective Ethics and Objective Ethics, as here explained, does not coincide with the difference between Individual Ethics and Social Ethics. Objective Ethics includes both the latter, since it recognizes individual peculiarities. It has yet to be decided whether, within the bounds of Objective Ethics, Individual Ethics and Social Ethics are dependent upon each other, or whether one, and if one then which one, determines the other. It has to be decided whether, according to the principle of welfare, the free self-development of the individual is to be limited by the conditions of social life, or vice versa. Within the limits of Objective Ethics, there may arise an Individualism of another sort than that before mentioned, founded, not upon the sovereignty of the individual, but upon the principle of welfare, which demands as many independent and peculiar points of departure for action as possible. The like is true, also, of the question of smaller organizations within larger ones.
The history of Ethics shows us that the ethical judgment of actions at first regarded the outer act itself and its results, but was gradually extended to include the motive, the disposition, the character of the acting subject. It is perfectly natural that regard should first be attracted to that which is the object of sense-perception. Moreover, action at an earlier stage of development is essentially reflex action, and the expression of instinct; the motives are simple and transparent, and interest does not linger long with them. The great revolutions in Ethics appear as essentially progress with regard to the importance accorded, in ethical judgment, to the inner factors of action. This greater inwardness is combined with a generalization; for the rejection of a motive is the rejection of all action occasioned by it, and the ethical acceptance of a motive the acceptance of all action springing from it. Hence the transference of regard to inner conditions represents a great simplification of the ethical law. Examples of such a transference may be found in the rupture between Christianity and Judaism, and between Protestantism and Catholicism.
In this way, too, Objective Ethics leads to Subjective Ethics. The objective judgment not only presupposes a subjective basis, but also finds some of its best objects in actions which spring from the same mental constitution which is the basis of the judgment. Here, the basis of mental constitution and the motive coincide; the ethical law demands the existence of the moral disposition by which it itself exists in the species. This Kant expresses in the assertion that it is a duty to possess conscience. Since the recognition of duties presupposes the existence of conscience, it might seem as if here were an argument in a circle. But that this is an illusion may be seen from the fact that the basis of ethical judgment and the motive do not necessarily coincide and that it is not necessarily an imperfection when they do not coincide. It may be necessary in some cases, in accordance with the principle of welfare, that other motives than the sense of duty shall guide the action; it may be necessary and healthful, for example, that in some cases man should be led by the instinct of self-preservation, or by an immediate sympathy, to labor for the welfare of others, and that conscience should not be aroused in every single act. It may even be a sign of perfection when actions that demand exertion and sacrifice are carried out without the intervention of a sense of duty. Indeed, mental drill in the end renders that which at first took place by means of a long psychological process of reflection and will, direct and without special consciousness of its reason.
All Ethics is practical Idealism. All systems assume an end, and an end is not anything at present existing, but something which ought to be. All systems assume, therefore, strong feeling, impulse, and endeavor, combined with the image of that which is the object of the endeavor. But the ideal must have points of contact with actuality, so that at least an approach to it is practicable; it must be physically, psychologically, and historically possible.
Ethical ideals deviate from the actual in three ways. In the first place, there is often in actual willing and doing something directly opposed to the principle of welfare. In this case, the office of Ethics is to restrain and forbid. To this function corresponds, in the practical life of the will, the hemming by which involuntary, original, or acquired impulses and inclinations are repressed. Again, actual willing and doing often exhibit only a weak and imperfect realization of that which Ethics demands. Here there must be an increase in the degree as well as in the extent of the realization. To this corresponds, in the practical life of the will, effort and attention, the power of the will, through its influence upon conceptions and feelings, to react upon itself. And finally, there may be, in willing and doing, a lack of unity and harmony; various opposed tendencies and impulses may make themselves felt. Here a process of harmonizing and concentration is necessary. And to this corresponds, in the practical life of the will, a drilling in connected action and trains of thought, and in the power to make an end of reflection by decision. In all three cases, the principle of welfare is to be followed; and the three processes are to be applied not only in the development of the individual but also in that of societies, and of the species.
That which manifests itself in conscience is a species-instinct. In the feeling of judgment, the relation between central and peripheral factors finds expression, neither of which, and least of all the central factors, are developed by individual experience, but both of which are, on the contrary, the product of the experience of the species. What Kant called the Categorical Imperative is, in fact, an instinct; and every instinct speaks unconditionally, categorically, gives no reasons and admits of no excuse.
No instinct finds expression without the existence of conditions which call it forth; but all manner of individual and social circumstances may furnish such conditions.
When conscience begins to be conscious of its office, it manifests itself as an Impulse.[77] The thought of actions which the instinctive judgment has recognized, or to the performance of which it has perhaps incited, is combined with pleasure, the conception of actions of the opposite nature with pain. The tendency arises to linger with the former and to repeat them, and to turn from the latter, if no stronger impulses of another sort make themselves felt.
