The code of natural ethics which Mr. Spencer propounds, and which is a product of the process of evolution, may be summarized as follows: Conduct is an aggregate of actions which are not purposeless, but which include all acts that are adjusted to ends, from the simplest to the most complex. The division or aspect of conduct with which ethics deals, the behavior we call good or bad, is a part of an organic whole; but, although inextricably bound up with acts which are neither good nor bad, it is distinguishable as comprehending those acts with which morality is concerned. The evolution of conduct, from the simplest and most indifferent actions up to those on which ethical judgments are passed, is what Mr. Spencer means by the scientific method of investigating the origin of morality. We must begin with the conduct of all living creatures, because the complete comprehension of conduct is not to be obtained by contemplating the conduct of human beings only. "The conduct of the higher animals as compared with that of man, and the conduct of the lower animals as compared with that of the higher, mainly differ in this, that the adjustments of acts to ends are relatively simple and relatively incomplete. And as in other cases, so in this case, we must interpret the more developed by the less developed. Just as, fully to understand the part of conduct which ethics deals with, we must study human conduct as a whole, so, fully to understand human conduct as a whole, we must study it as a part of that larger whole constituted by the conduct of animate beings in general."[128]

Begin, for example, with an infusorium swimming about at random, determined in its course not by an object which it perceives and which is to be pursued or escaped, but apparently by varying stimuli in its medium, the water. Its acts, unadjusted in any appreciable way to ends, lead it now into contact with some nutritive substance which it absorbs, and now into the neighborhood of some creature by which it is swallowed and digested. Pass on to another aquatic creature, which, although of a low type, is much higher than the infusorium, such as a rotifer. With larger size, more developed structures, and greater power of combining functions, there comes an advance in conduct. It preserves itself for a longer period by better adjusting its own actions, so that, it is less dependent on the actions going on around. Again, compare a low mollusk, such as a floating ascidian, with a high mollusk, such as a cephalopod, and it is apparent how greater organic evolution is accompanied by more evolved conduct. And if you pass then to the vertebrate animals, you see how, along with advance in structure and functions, there is evolved an advance in conduct, until at length, when you reach the doings of the highest of mammals, mankind, you not only find that the adjustments of acts to ends are both more numerous and better than among the lower mammals, but you find the same thing on comparing the doings of the higher races of men with those of the lower races. There is a greater completeness of achievement by civilized men than by savages, and there is also an achievement of relatively numerous minor ends subserving major ends.

Recollecting, then, what conduct is—namely, the adjustment of acts to ends—and observing how this adjustment becomes more and more complete as the organism becomes more developed, we have to note the order of the ends to which the acts are adjusted. The first end, the first stage of evolving conduct, is the further prolongation of life. The next is that adjustment of acts to ends which furthers an increased amount of life. Thus far the ends are complete individual life. Then come those adjustments which have for their final purpose the life of the species. Then there is a third kind of conduct, which results from the fact that the multitudinous creatures which fill the earth can not live wholly apart from one another, but are more or less in presence of one another, are interfered with by one another. No one species can so act as to secure the greatest amount of life to its individuals and the preservation of the species—can make a successful adjustment of its acts to these ends—without interfering with the corresponding adjustments by other creatures of their acts to their ends. That some may live, others must die. Finally, when we contemplate those adjustments of acts to ends which miss completeness, because they can not be made by one creature without other creatures being prevented from making them, we reach the thought of adjustments such that each creature may make them without preventing them from being made by other creatures. Let me now quote Mr. Spencer's concrete illustrations of these abstract statements:

"Recognizing men as the beings whose conduct is most evolved, let us ask under what conditions their conduct, in all three aspects of its evolution, reaches its limit. Clearly while the lives led are entirely predatory, as those of savages, the adjustments of acts to ends fall short of this highest form of conduct in every way. Individual life, ill carried on from hour to hour, is prematurely cut short; the fostering of offspring often fails, and is incomplete when it does not fail; and in so far as the ends of self-maintenance and race-maintenance are met, they are met by destruction of other beings, of different kind, or of like kind. In social groups formed by compounding and recompounding primitive hordes, conduct remains imperfectly evolved in proportion as there continue antagonisms between the groups and antagonisms between members of the same group—two traits necessarily associated; since the nature which prompts international aggression prompts aggression of individuals on one another. Hence, the limit of evolution can be reached by conduct only in permanently peaceful societies. That perfect adjustment of acts to ends in maintaining individual life and rearing new individuals, which is effected by each without hindering others from effecting like perfect adjustments, is, in its very definition, shown to constitute a kind of conduct that can be approached only as war decreases and dies out.

"A gap in this outline must now be filled up. There remains a further advance not yet even hinted. For beyond so behaving that each achieves his ends without preventing others from achieving their ends, the members of a society may give mutual help in the achievement of ends. And if, either indirectly by industrial co-operation, or directly by volunteered aid, fellow-citizens can make easier for one another the adjustments of acts to ends, then their conduct assumes a still higher phase of evolution; since whatever facilitates the making of adjustments by each, increases the totality of the adjustments made, and serves to render the lives of all more complete."

In the outline which I have now given you of the evolution of conduct, you will perceive the foundation of Spencer's system of ethics. Actions begin to assume an ethical character—conduct becomes good or bad—when the acts tend to promote or to prevent the general well-being of the community. But how is the perception or recognition of this quality in an action reached? What is the determining reason for considering an action good or bad? Obviously, conduct is considered by us as good or bad according as its aggregate results to self, or others, or both, are pleasurable or painful. Mr. Spencer shows that every other proposed standard of conduct derives its authority from this standard: "No school can avoid taking for the ultimate moral aim a desirable state of feeling called by whatever name—gratification, enjoyment, happiness. Pleasure somewhere, at some time, to some being or beings, is an inexpugnable element of the conception. It is as much a necessary form of moral intuition as space is a necessary form of intellectual intuition."[129]

On this fundamental basis, Mr. Spencer rests his system of absolute ethics and relative ethics. Relative ethics are those by which, allowing for the friction of an incomplete life and the imperfections of existing natures, we may ascertain with approximate correctness what is the relatively right. This is often exceedingly difficult, because two cases are rarely the same in all their circumstances. But absolute ethics are the ideal ethical truths, expressing the absolutely right. Such a system of ideal ethical truths, which must have precedence over relative ethics, is reached only when there has been, in conformity with the laws of evolution in general, and in conformity with the laws of organization in particular, an adaptation of humanity to the social state, changing it in the direction of an ideal congruity. But, as in relative ethics, the production of happiness or pleasure is the aim, however imperfectly accomplished, so in the ideal state the aim is the same, the difference being that in the latter the accomplishment of happiness or pleasure and the exclusion or prevention of pain are complete.

Sophereus. And do I understand you that in this system of ethics the idea of a moral law proceeding from and consisting of the command of a Supreme Lawgiver is left out?

Kosmicos. Certainly it is. Did I not just now read to you from Mr. Spencer's preface his complete rejection of the supposed sacred origin of moral injunctions, and what he says of the necessity for the secularization of morals to take the place of that system which is losing its authority?
