Life not alone determines morality, but it determines religion as well. What else is the meaning of all those discarded forms of religious belief, those bodies of dead gods, that meet the student of history as the remains of extinct animals meet the geologist in his unravelment of the story of the earth's vicissitudes? They are the result of a lack of adaptation to new conditions to which they could not accommodate themselves. Once the gods lorded it over man as the gigantic dinosaur lorded it in his day over lesser animals. And in the one case, as in the other, a change in the environment brought about their doom. Natural selection determines the survival of religions as of animal forms, and a religion to survive must become increasingly utilitarian in character, certainly there is a point beyond which the opposite tendency cannot be carried.
Assume, for example, that a religion existed of a grossly anti-social character, one that teaches doctrines that are subversive of the general social well-being. One of two things must result. If the religion is strong enough to enforce its teaching the society it dominates will disappear, and the religion will die out with it. If, on the other hand, it cannot enforce its teaching, or can get it accepted only in a modified form, then either the religion disappears in its original form, or it is modified to get itself established. To live, religion must establish some sort of harmony between its teachings and the conditions of life. It may retard the development of life, but it must not retard to the point of destruction. This is all that is really involved in what is called the purification of religious teaching. In reality there is no such thing. The purification is a modification, and it is modified in order that it may become acceptable to the society in which it is existing. The ascetic epidemic, the various disgusting sects that have sprung into existence from time to time during the course of Christian history, have all died out from this cause. As with the individual, so with society, the forces of which we are conscious generally move upon the surface. Of the underlying ones we are mostly unaware.
The truth is, then, that behind all our consciously elaborated theories of life there are operative the unconscious or sub-conscious forces of evolution. There is, of course, a certain area of conduct in which speculative opinions play their part, and where actions may be arbitrarily classed as good or bad. But this area is, of necessity, limited, and for the reasons that have been given above. Properly understood morality is not something very abstract, but something that is very concrete. The underlying reason for morality is always the same, and we are compelled to hark back to it for justification. And no rejection of religion can alter the basis upon which morality rests.
The proposition that Atheist, Agnostic, and Theist breathe the same atmosphere and are affected by the same influences is, therefore, one that is two-edged. If our intellectual atmosphere is saturated with religious influences, it is also saturated with social influences of a much more fundamental character, and which have been perpetually correcting religious extravagances. And it is at least open to the Atheist to retort that we have to thank this circumstance that religious beliefs have not been more injurious than has been actually the case. If, for example, the ascetic epidemic of the early Christian centuries had increased in force and had continued operative, European society would have disappeared. That this was not the case was due to the strength of the sexual and social instincts, against which religion was unable to maintain its hold. In the change of opinion over the better way to spend Sunday, or in the decay of the doctrine of eternal damnation, we have the same point illustrated. Right through history it has been the social instincts that have acted as a corrective to religious extravagance. And it is worth noting that with the exception of a little gain from the practice of casuistry, religions have contributed nothing towards the building up of a science of ethics. On the contrary it has been a very potent cause of confusion and obstruction. Fictitious vices and virtues have been created and the real moral problem lost sight of. It gave the world the morality of the prison cell, instead of the tonic of the rational life. And it was indeed fortunate for the race that conduct was not ultimately dependent upon a mass of teachings that had their origin in the brains of savages, and were brought to maturity during the darkest period of European civilisation.
In dealing with the two first propositions I have, by implication, answered the third—namely, that a wholly secular authentic code of morals would be inadequate to form the highest type of character; it might supply a "must," but it could not supply an "ought."
The first and obvious reply to an objection of this kind is that our working code of morals is secular already. In life, if we observe without prejudice, it is not difficult to see that one's neighbours, friends, social class, etc., have far more force in shaping conduct than speculative theories. In its widest sense natural selection determines what actions shall be declared to be moral. Of this we may take the universal feeling against homicide. This is but an expression of the truth that social life would be impossible were it otherwise. And when we pass from the general to the special we meet with much the same principle operating in society. The average burglar pursues his calling with no special sense of its wrongness, although he may have a keen sense of its dangers. But while burgling with a fairly easy conscience, he does flinch at breaking the code of honour set up by his fellow-burglars. And at the other extreme we have the "gentleman" with his code of honour which forbids him not to pay a gambling debt, but takes no count of keeping a poor tradesman out of his money. In each of these cases the determining factor is not theory but fact, and the fact here is association with our fellow countrymen or with a special social class. Morality, in short, is social or nothing. Moral laws are meaningless apart from social life. Every moral command implies the existence of a social medium, and it is no more than a study in history to see how this social medium has been continuously shaping and reshaping human nature. The determination here is not conscious, but it is real, however much disguised it may be by various forms or theories. And when we realise this, it is no more than a truism to say that a change in religious belief can no more destroy morality than a change in government can destroy society.
But in saying that the essence of morality is unreasoning I do not mean that it is unreasonable. All I mean is that it can receive a reasonable justification, and that no matter how lofty the development it has its basis in the fundamental conditions of associated animal and human life. We may surround the subject with a vague and attractive idealistic verbalism, but we come back to this as a starting point. The love of family, with all its attendant values, rests upon the fact of crude sexual desire, refined, of course, during the passing of many generations, but dependent upon it all the same. Remove the sexual desire and the family feelings are inexplicable. Thus, the reason for the existence of the sexual instinct is race preservation, but the end has been achieved in a quite unreasoning manner. In the animal world at large there is certainly no conscious desire for the production of offspring, nor is there with the mass of human beings. There is the desire to gratify an impulse, and very little more. And for the strengthening of an instinct there need not be, nor is there, any consciousness of its social value. All that is necessary is that it shall be useful. Natural selection attends to the rest.
This will, I think, supply an answer to the contention that secular ethics can supply a "must," but not an "ought"; that is, it may show that an individual should act in accordance with his inclinations, but in cases where these clash with the social well being, it can supply no reason why the former should give way to the latter.
The argument rests upon a dual confusion. First, the moral "ought" is no more than an organised and conscious form of "must," and not something distinct from it. One may test the matter by taking a case. A man says, I ought so to work as to promote the general welfare of society. If we seek to find the source of this feeling we come ultimately upon the feeling of tribal solidarity in virtue of which certain tribes survive in the struggle for existence. It is gregariousness struggling into consciousness. The moral "ought" is an idealised form of the primitive tribal "must." And the "must" of primitive life is encouraged and developed because it is one of the conditions of survival.
The second point of confusion is based upon a supposed opposition between individual inclinations and an ideal conception of duty. That the two are often, as a matter of fact, in conflict, must be admitted. And the cause is that while our inclinations represent a heritage from the past, our ideals are a projection into the future. But the contention is based upon their supposed permanent hostility, and that need not be taken for granted. For the whole course of social evolution tends to bring about a substantial identification of personal and social well-being. More and more as the race develops it is being recognised that there is no real individual life apart from social life, of which it is the creation and the expression. Such antagonism as exists is the inevitable result of a conflict between an organism and its adaptation to a changing environment. And from this point of view the whole growth of man is in the nature of an expansion of his sympathies and sense of duty over an ever-widening area. The primitive egoism of the tribal individual is extended to the nation, that of the nation to the empire, and thence to the whole of humanity. There is no destruction or denial of self in such cases, it is a development of the sense of self over an enlarging area.
