(2) We find, by looking into their books, that men most intimately acquainted with the facts of the moral life as revealed in different races and peoples may differ widely in the ethical doctrine which they are inclined to base upon them. Not all men, even when endowed with no little learning, are gifted with the clearness of vision which can detect the significance of given facts; nor are all equally capable of weaving relevant facts into a consistent and reasonable theory. The keenness and the constructive genius of the individual count for much. And breadth of view counts for much also. We have seen that ethics touches many fields of investigation, and the philosopher is supposed, at least, to let his vision range over a broad realm, and to grasp the relations of the different sciences to each other. He is, moreover, supposed to be trained in reflective analysis, and of this ethical theory appears to stand in no little need.
(3) Finally, the mere fact that ethics has for so many centuries been regarded as one of the disciplines falling within the domain of the philosopher is not without its significance. One may deplore the tendency to base ethics upon this or that metaphysical doctrine, and desire to see it made an independent science; and yet one may be compelled to admit that it is not easy to comprehend and to estimate the value of many of the ethical theories which have been evolved in the past, without having rather an intimate acquaintance with the history of philosophy. The ethical teachings of Plato, of Aristotle, of St. Thomas, of Kant, of Hegel, of Green, lose much of their meaning when taken out of their setting. The history of ethical theory is blind when divorced from the history of philosophy, and with the history of ethical theory the moralist should be acquainted.
The philosopher has no prescriptive right to preempt the field of ethics. Many men may cultivate it with profit. Nevertheless, he, too, should cultivate it, not independently and with a disregard of what has been done by others, but in a spirit of hearty cooperation, thankfully accepting such help as is offered him by his neighbors.
CHAPTER VII
THE AIM OF ETHICS AS SCIENCE
19. THE APPEAL TO REASON.—The proper aim of the scientific study of ethics appears to be suggested with sufficient clearness by what has been said in the chapters on the accepted content of morals.
Where individuals take up unreflectively the maxims which are to control their conduct, human life can scarcely be said to be under the guidance of reason. Where, moreover, the codes of individuals clash with each other or with the social conscience of their community, and where the codes of different communities are disconcertingly diverse, planful concerted action with a view to the control of conduct appears to be impracticable. Historical accident, blind impulse and caprice, cannot serve as guides for a rational creature seeking to live, along with others, a rational life.
"The aim of ethics," says Sidgwick, [Footnote: The Methods of Ethics, Book I, chapter vi, Sec 1.] "is to render scientific—i.e., true, and as far as possible systematic—the apparent cognitions that most men have of the rightness or reasonableness of conduct, whether the conduct be considered as right in itself, or as the means to some end conceived as ultimately reasonable." The use here of the word "cognitions" calls our attention to the fact that, when men say, "this is right, that is wrong," they mean no more than, "this I like, that I do not like"; and the use of the word "apparent" indicates that the judgments expressed may be approved by the man who makes them, and yet be erroneous. The appeal is to an objective standard; there is a demand for proof.
That most men recognize, in some cases dimly, in some cases clearly and explicitly, that the appeal to such a standard is justifiable, can scarcely be denied. Between "I choose" and "I ought to choose," between "the community demands," and "the community ought to demand," men generally recognize a distinction when they have attained to a capacity for reflection.
It has, however, been denied that the appeal is justifiable, and denied by no mean authority. "The presumed objectivity of moral judgments," writes Westermarck, [Footnote: 2 The Origin and Development of the Moral Ideas, chapter i, p. 17.] "being a chimera, there can be no moral truth in the sense in which this term is generally understood. The ultimate reason for this is, that the moral concepts are based upon emotions, and that the contents of an emotion fall entirely outside the category of truth. But it may be true or not that we have a certain emotion, it may be true or not that a given mode of conduct has a tendency to evoke in us moral indignation or moral approval. Hence a moral judgment is true or false according as its subject has or has not that tendency which the predicate attributes to it. If I say that it is wrong to resist evil, and yet resistance to evil has no tendency whatever to call forth in me an emotion of moral disapproval, then my judgment is false." The conclusion drawn from this is that there are no general moral truths, and that "the object of scientific ethics cannot be to fix rules for human conduct"; it can only be "to study the moral consciousness as a fact."
