I shall try, in the briefest possible manner, to give an outline of the most important ethical problems.

Ethical judgments, judgments concerning good and bad, in their simplest form are expressions of feeling, and never lose that character however much influence clear and reasoned knowledge may acquire with respect to them. An act or an institution that could awaken no feeling whatsoever would never become the object of an ethical judgment, could never be designated as good or bad. And the character of the judgment will be dependent upon the character of the feeling that dictates the judgment. From the point of view of pure egoism the judgment of the same act will be wholly different from what it is when regarded, say, from a point of view that is determined by motives of sympathy embracing a larger or smaller circle of living beings. An ethical system, accordingly, will acquire its character from the motive principle of judgment upon which it builds. This motive principle is the power that originally and constantly again gives rise to ethical judgments.

If our motive principle is to operate with clearness and logical consequence it must set up a definite standard. A test principle of judgment must be established that will furnish guidance in individual cases by enabling us to infer consequences from it in instances where simple, instinctive feeling fails. The natural course will be that the test-principles will correspond directly with the motive principles at their base. The relation between the two may, however, be more or less simple. If we fix upon the feeling of sympathy as our basis, regarding it as the main element of ethical feelings, it follows of itself that the criterion we adopt must be the principle of general welfare, that is the principle that all acts and institutions shall lead to the greatest possible feeling of pleasure among living beings. This principle merely defines with greater precision what is unconsciously contained in the feeling of sympathy and in the instinct that springs from this feeling. The same test-principle (as Bentham's "Deontology," for example, shows) may also be accepted as valid from the point of view of pure egoism, only in this case the relation between the motive principle and the test-principle is more indirect. We must in this case endeavor to prove that the happiness of others is a necessary means to our own happiness. Our own happiness is then the real end, but in order to reach this end we must take a roundabout course, and ethics is the presentation of the system of the courses thus taken. Kant arrives in a different way again at establishing the happiness of others as an end of ethics. It would be the business of a special investigation to determine the extent to which this varying motivation of the principle of test must influence the consequences derivable from it.

A third question is, By what motive shall an individual act be determined? The motive to action is not necessarily the same as the motive that dictates judgment. The man who is animated with love for his fellow-creatures has reason to rejoice that ambition and the instinct of acquisition constitute grounds of action of so very general a character; in that results become thereby possible which,—for such is the unalterable character of human nature,—would otherwise remain unaccomplished. A special investigation would have to point out whether cases occur in which motive of action and motive of judgment must coincide if the act is to be approved of, and whether there are not motives to action which would rob the act of all ethical character.

Different from the problems already mentioned is the pedagogic problem: How can the proper and necessary motives be developed in man? This problem arises as well with respect to the motive principle of judgment as with respect to the motive principle of action. It is clear that between points of view that rest upon entirely different psychological foundations, (the one, for example, starting from egoism, the other from sympathy, and the third from pure reason,) the discussion can be carried only to a certain point. The person who with conscious logic makes himself the highest and only aim can never be refuted from a point of view which regards every individual as a member of society and of the race, and therefore not only as an end but also as a means. If an understanding is to become possible, the emotional foundation adopted (the motive spring of judgment) must be changed; but the change is not effected by mere theoretical discussion: a practical education is demanded in addition thereto which life does not afford all individuals, although our inclination to make ourselves an absolute centre is always obstructed by the tendency of society to subject us all to a general order of things. There is an education of humanity by history the same as there is an education of single individuals in more limited spheres. This education demands its special points of view, which are not always directly furnished by general ethical principles. The same is true of the motive to action. For pedagogical reasons it may be necessary to produce or to preserve motives that do not satisfy the highest demand, because such motives are necessary transitional stages to the highest motives. Thus, ambition and the instinct of acquisition may be the means of attaining to true ethical self-assertion. Reverence for authorities historically given can be of extraordinary effectiveness in the development of character, since only thereby are concentration or fixity of endeavor as well as the power of joyful resignation acquired,—without our being able to see in such reverence the highest ethical qualities. A ground-color in fact must often be laid on before the final, required tint can be applied. The law of the displacement of motives operates here which in ethical estimation generally is of the utmost importance.

There must still be mentioned here finally the socio-political problem. This problem has reference to that particular ordered arrangement of society which is best adapted to a development in the direction of ethical ideals. As the former problem leads inquiry out of the domain of ethics into that of pedagogics, so this one leads us from ethics into political economy and political science.

Although in the present discussion I intend to occupy myself only with a single one of these problems, I have nevertheless mentioned them all in order that the light that I shall attempt to throw upon the problem I deal with may be seen in its proper setting. As will be observed from what follows, the principle of welfare will be misunderstood if the problem to whose solution it is adapted is confounded with any one of the other ethical problems. The systematism of ethical science is still so little advanced that it is necessary to draw out a general outline before we pass on to any single feature. The value of systematism is namely this, that we are immediately enabled to see the connection of the single questions with one another as well as their distinctive peculiarity. In ethics we are not yet so far advanced.

II.

1) If we accept the principle of welfare as our test or criterion in judging of the value of actions and of institutions, these are then good or bad according as in their effects (so far as we can trace them) they produce a predominance of pleasurable feeling or a predominance of painful feeling in a larger or smaller circle of sentient beings. Every action may be compared to a stone thrown into the water. The motion produced is propagated in large or in small circles; and the estimation of its value depends upon whether it produces in the places it strikes predominant pleasure or pain. Just as theoretical science explains the single natural phenomenon by its connection with other natural phenomena, so ethics tests the single feeling by its relation to other feelings: the satisfaction of a person acting over the accomplishment of the act is only then to be called justifiable or good when it does not create a disturbance in the pleasurable feeling of other beings, or when such a disturbance can be proved to be a necessary means of a greater or more extended pleasurable feeling. This principle, as a principle of test or valuation, corresponds directly with sympathy as motive of judgment. The extent to which it is possible to accept this from other points of view I cannot here investigate in detail.

The act of estimation, the testing, does not stop at the outer action but goes down to the motives of the person acting, to the qualities of his character, to the whole inner life from which the act has sprung. This has its ground in the nature and significance of the estimating judgment. Ethical judgments, in fact, are in their original and simplest form spontaneous expressions of feeling. But the great practical significance of such expressions of feeling lies in the fact that they operate decisively upon the will (upon the individual will and that of others) and produce motives of future action. Logically, accordingly, they must be directed towards the point at which an altering effect on the power that produces the act is possible, and this point lies precisely in the inner life, in the character of mind of the person acting. For this reason feelings and impulses, disturbances and desires, are also judged of according to the tendency which they have of producing acts and effects that will increase pleasurable feeling or avoid unpleasurable feeling in more extended or more limited circles.
