Following upon the increased recognition of pleasure and pain as motives, and upon the increased amount of rational judgment as to the sequences of actions, has come the adaptation of conduct to the pains and pleasures of others. Those adaptations have, however, been relative to the particular constitution of the Ego, and relative also to the constitution of the environing Egos.

The knowledge of the existence of sentiency in external organisms may be turned to the account of the Ego by inflicting pain, so as to coerce other sentient organisms to its own selfish objects; or, again, by conferring pleasure, so as to subserve the same end. Thus cruelty may be a natural pleasure in certain early stages of development, as a concomitant of necessities of existence, and may remain by inheritance long after the necessities have passed away. But with the increase of life has occurred the increase of sympathy. It is a law of nature that after the pleasures of the ego are satisfied they are augmented by the contemplation of similar enjoyments of others. But this again is relative. The gourmand likes the society of gourmands, and cares not for the company of the æsthetic or the ascetic. The man of taste revels in the society of kindred natures and despises the pleasures of the base. But the family relation has been the main source of all sweet and manly sympathies: and it has been the gradually widening scope of social organisations which has spread more and more the feeling of human sympathy. The course of history exhibits to us a constant growth, not merely in passively refraining from the infliction of pain, but also in the active endeavour to promote the happiness of our fellow creatures.

This is a general statement of the scientific view of purposed conduct. Its laws are derived from a study of its growth. The growth is one exhibiting several distinguishable features. There has been the ordinary biological "struggle for existence," and "survival of the fittest." There have been adaptations necessitated by the action of the environment, and there have been chance variations within the lines of causation which, benefitting the individual or some particular race, have given them such an advantage in the battle of life as to secure for their descendants a preponderating possession of the good things of the world. There has been the increase of intelligence, the increase in the organisation of society, the increase of rational judgments of phenomena and human actions. There has been increased knowledge of the determination of actions by motives. There has been increase of sympathy.

But what is the ethical virtue of this historical study is not very clear. The history of human developments is a matter of natural history and no more. And even if we proceed as we might do, to study more in detail the history of the development of notions of right and wrong and of the various changeful applications of those terms, we are still within the limits of a natural history—we are still holding the merely scientific or observant attitude. It is true such study may be essential to our future history: but the mere study of what has been, and the consequent pre-vision of what will be, establishes no rule of right. To prophecy the determining courses of future human conduct does not furnish an ethical imperative to the individual. "If so it will be," he may say, "so let it be, it is no affair of mine. The obligation rests with nature and not with me." Whence then the new "regulative system," the want of which fills Mr. Spencer with alarm? Where shall we look for the new gospel which shall restrain and vivify the moral conduct of future generations in place of the supernatural systems which are supposed to be tottering to their fall?

And if we go beyond this and find that this natural history of man is governed by general laws of adaptation and development we shall still have to question the ethical discernment and ethical authority in special junctures, when what is—is judged not to be what it ought to be; when, in fact, adaptations or biological facts, or equilibrations produced by evolution, are judged not to be ethically good equilibrations.

However, Mr. Spencer holds that rules of right conduct can be established on a scientific basis, and it is our task to examine his treatment of the problem.

"Though this first division of the work terminating the Synthetic Philosophy, cannot, of course, contain the specific conclusions to be set forth in the entire work; yet it implies them in such wise that, definitely to formulate them requires nothing beyond logical deduction.

"I am the more anxious to indicate in outline if I cannot complete this final work, because the establishment of rules of right conduct on a scientific basis is a pressing need. Now that moral injunctions are losing the authority given by their supposed sacred origin, the secularization of morals is becoming imperative. Few things can happen more disastrous than the decay and death of a regulative system, no longer fit, before another and fitter regulative system has grown up to replace it. Most of those who reject the current creeds, appear to assume that the controlling agency furnished by it may be safely thrown aside, and the vacancy left unfilled by any other controlling agency. Meanwhile, those who defend the current creeds allege that in the absence of the guidance it yields, no guidance can exist; divine commandments they think the only possible guides. Thus between these extreme opponents there is a certain community. The one holds that the gap left by disappearance of the code of supernatural ethics, need not be filled by a code of natural ethics; and the other holds that it cannot be so filled. Both contemplate a vacuum which the one wishes and the other fears. As the change which promises or threatens to bring about this state, desired or dreaded, is rapidly progressing, those who believe that the vacuum can be filled, are called on to do something in pursuance of their belief."[8]

It is clear, from the above passage, that Mr. Spencer seeks not merely a knowledge of the laws of past developments, which have landed us in our present position with regard to moral obligation in general and the varied social regulations extant in different societies, but he seeks in addition to strengthen and establish on a new basis the authority of all such obligations. What Mr. Spencer hopes for is a practical end. He seeks the art of good living. As there are sciences of chemistry, metallurgy, electricity, etc., and arts consequent upon them, so he looks for Rules of Life which shall benefit humanity, consequent upon the Science of Humanity. But it is a question whether the Moral Imperative can be regarded as the result of science. However, if not the result, yet science may be able to discern that the Moral Imperative is so firmly established in human nature, that it may be able to proclaim loudly its empire in the heart and over the actions of man; while at the same time Science may be able to guide it to wiser and better judgments.
