Mr. Spencer argues well in Chapter V. as to the concomitance of pleasure-giving acts with life-sustaining acts, and of pain-giving acts with decrease of life; but which is prior in the chain of causation? Or, to repeat the old difficulty, is the subjective factor present in the line of causation at all? Is it merely a concomitant of the physical line of events?
Mr. Spencer proposes to deal with feelings and functions in their mutual dependence,[9] and so admits the subjective as a factor. Thus there are feelings which are sensations and serve partly as guides and partly as stimuli towards actions for the sustenance and preservation of life. And there are feelings which are classed as emotions which also act in a very potent way as guides and stimuli, such as fear and joy. Hence, in treating of conduct under its biological aspect we are compelled to consider that inter-action of feelings and functions which is essential to animal life in all its more developed forms.[10]
Following upon this we are taught that Pleasure is a feeling which we seek to bring into consciousness, and Pain a feeling which we seek to keep out of consciousness. This certainly accords to the subjective factor a commanding position in the physical action of organisms; it also implies a foresight of the results of actions, and a certain degree of advance in psychology but throws no light upon the lower stages of biological action. Mr. Spencer says, however, that "fit connections between acts and results must establish themselves in living things even before consciousness arises." This is followed by an interesting study of the proposition that "after the rise of consciousness these connections can change in no other way than to become better established," and that "whenever sentiency makes its appearance as an accompaniment, its forms must be such that in the one case the produced feeling is of a kind that will be sought—Pleasure, and in the other case is of a kind that will be shunned—Pain." "It is an inevitable deduction from the hypothesis of evolution that races of sentient creatures could have come into existence under no other conditions" than that "pains are the correlatives of actions injurious to the organism, while pleasures are the correlatives of actions conducive to its welfare."
All this may be admitted, granted the existence of the subjective factor; but at what stage does it commence to have such a potent influence upon the development of organisms, and whence came it at all? Mr. Spencer says, "fit connections between acts and results must establish themselves in living things even before consciousness arises." "At the very outset life is maintained by persistence in acts which conduce to it, and desistance from acts which impede it." It would seem that if life can be maintained by means of unconscious persistence in beneficial acts and unconscious desistance from injurious acts, such a process might continue in more complex organisms without the assistance of consciousness, and that the continuance and development of life could be explained in terms of the same factors and processes which originated life, and regulated and propagated the existence of races in the lowest forms of organisms. Mr. Spencer clearly holds that such races of organisms were originated and maintained by the action of physical laws before sentiency became a factor in their sustaining or generative actions. What need then for sentiency in the subsequent development? Mr. Spencer's argument is good, that, granted the concomitance of Pleasure and Pain with life-sustaining and life-diminishing acts respectively, the attainment of the one and the avoidance of the other acts on the increase of life; but he says that, previous to the advent of sentiency, life was sustained in much the same way. There is this difference in it, however, that only where the requisite acts were performed or avoided in pre-sentient organisms did such organisms continue to exist, and that these acts were not consciously performed, but only happened in the course of physical sequence; whereas in the case of sentient creatures Pleasure is consciously sought, and Pain is intentionally avoided. But it seems to us that when acts are determined by the anticipation of Pleasure or Pain, we enter upon the domain of psychology, and when they are determined by physical factors without consciousness we remain in the province of physics, so that there is no intermediate science of Biology at all. And by this we mean, not that for convenience we may not so arrange our classes of study, but that there are no laws of physics which will account for the development of organisms, and there are no biological processes which do not imply the action of a subjective factor; and that there is no true biological law which properly expresses the correllation of the two. Mr. Spencer starts with a Biology from which the subjective is completely absent, and ends with a Psychology of the highest description: but he fails to express the biological law which accounts for the growth of the one out of the other, or expresses the law of their correlation in a concomitant growth.
How then can we arrive at any ethical rule by the study of Biology? In this way. An organism is a moving equilibrium: it is a law of moving equilibria that they counterbalance by means of new adjustments antagonistic forces in the environment, and absorb forces from the environment favourable to their continuance. Their continued existence depends upon such continuous absorption and adjustment. But as environment varies, so do adjustments; and thus there is a wonderful variety of different moving equilibria, which form important parts of one another's environment. The suitable structures and functions which have thus been evolved are therefore relative to the environment, and the inherited structure and functions forming a moving equilibrium are fitted for particular environments and no other. There is no absolute moving equilibrium; all are relative. "That which was defined as a moving equilibrium, we define biologically as a balance of functions. The implication of such a balance is that the several functions in their kinds, amounts, and combinations, are adjusted to the several activities which maintain and constitute complete life; and to be so adjusted is to have reached the goal towards which the evolution of conduct continually tends." But completeness of life means primarily the completeness of life in each individual organism as regards its continued existence, and the full satisfaction of all its functions during the period of its existence. The biologically good is all that conduces to this end, and the biologically bad is all that detracts from it. The biologically good and bad are therefore relative to the consensus of functions which constitute an animal or other organism. The biologically good and bad are therefore individual. That which is good for the individual is the right conduct, and that which is bad for it is wrong conduct. It is therefore right for the big fishes to eat the little ones, for the bird to prey upon the insect; it is a fit satisfaction for the functions of the lion to devour the antelope, for one tribe to slay or drive out another tribe in order to possess itself of more fertile plains and more delightful countries. And so, as long as the functions delight in egoism, and there is no counterforce of sympathy included among them, it is right to tyrannise, to subject others to the service or passions of the dominant organisms. They subserve the biological law—they are conducive to complete relative life. The biological law does not recognise the lives of others until sympathy has become part of the functions of the organism.
The question here arises, how far the ethical law is to be determined by the biological law, for if the biological law is dominant, and the ethical dependant, the latter can only be explained and justified by the former. But we at once see that the two things are not identical and co-extensive. We recognise the difference between the biologically efficient and the ethically good and bad. The law of Biology refers to the actions of each individual in regard to itself alone, whatever the functions, etc., which constitute that self. It relates to its good alone, irrespective of the good of others, unless, and until, sympathy with others has become part of the functions of the individual.
But Mr. Spencer seeks to make the biological view of conduct identical with the ethical by introducing the conception of quantitative life. In this case an organism has more life the greater the number of correspondences it has with the environment. And since the environment is constituted of two classes of objects, the objective and the subjective—the purely physical and the organisms possessing feeling—so the correspondences established in the individual are of two kinds, the psychological and the emotional. In the former class are comprised all the objects and relations of the inorganic world, the great laws and intricacies of nature and her past history, including the history of organisms and of man. In the latter are included all the feeling, living creatures around us, with their pleasures, hopes, and pains, and all the characters, noble and beautiful, delicate or brutal, passionate or aspiring, who have ever trod the stage of history, or wrought or thought for us in antecedent ages. In fact all the patient work and mighty achievements of science, and all the emotional relations of men have afforded scope for the quantitative increase of life; and in proportion to the increase so it is suggested that life became ethical. The biological law is the continuous adjustment of organisms to environment, and the increase of adjustment is the increase of life.
This may be so; but it is a denial of Ethics as being coeval with Biology; it makes the one simply a late outcome of the other. According to this view, Ethics is something which has supervened upon the process, and which requires a separate analysis. But we have seen that increase of correspondence is of two kinds—it takes place in the direction of intellect, and it takes place in the direction of emotion, whether of sympathy or antipathy. But it is with the latter class of phenomena alone that Ethics is concerned. The increased quantitative life which is identical with the increase of knowledge has no ethical aspect. It is increased relations of an emotional nature only which admit that term. In fact it is to societarian relations alone that it is applicable. Increase of life may proceed in the direction of intellect or recognition of the facts and relations of the external world, and yet the life may never be termed ethical; while on the other hand there may be but little increase of intellect, yet a great increase of ethical relations. Therefore, increased quantitative life, considered as a mode of identifying the biological law with the ethical law, except by way of comprehension in a larger classification, fails in the end because it is not true that the increase of correspondences need be in the special direction of increase of emotional correspondences: and thus we find that ethics is not to be affiliated upon the main line of biological progress, but with one distinguishable result of it—namely the relation of the individual with its subjective environment—that is to say, Society.
And here it is fit that we should take notice of Mr. Spencer's account of Good and Bad Conduct, given in chapter 3 of the "Data of Ethics." A good knife, gun, or house are such in virtue of their capacity for fulfilling the purposes for which they were designed. A good day or a good season are such as satisfy certain of our desires. A good pointer or a good ox are so in reference to certain of our requirements. A good jump, or good stroke at billiards, are those which accomplish the desired ends. And bad things are those which do not subserve desired ends.
Mr. Spencer then proceeds to study the ethically good and bad, and to discuss the application of these terms to actions as regards the welfare of self, of offspring, and of fellow citizens. Acts are said to be good and bad according as they affect the welfare of self. Here it is indicated that acts are judged according to their degree of biological efficiency. In the next class—namely, acts relating to offspring—a father and mother are again judged according to their efficiency in those capacities, although the egoistic element is present in a subordinate degree. "Most emphatic, however, are the applications of the words good and bad to conduct throughout that third division of it comprising the deeds by which men affect one another. In maintaining their own lives" (biological laws) "and fostering their offspring, men's adjustments of acts to ends are so apt to hinder the kindred adjustments of other men, that insistence on the needful limitations has to be perpetual; and the mischiefs caused by men's interferences with one another's life-subserving actions are so great, that the interdicts have to be peremptory."
