On the other hand, the progressive peoples have been those who remained in a savage or barbarous condition until a relatively late period, and who then acquired by imitation the arts of writing and of reducing custom to written law, acquired them in a fully developed condition from the peoples who had invented and developed these arts. They have, therefore, enjoyed the advantages of written laws from the beginning of their civilisation.

But, as Maine recognised, the acquisition of writing at the outset of national life is by no means sufficient to account for the progressiveness of the nations of South and Western Europe; we must seek other causes and conditions of their mental progress.

We have already noted certain features of the racial constitution which were probably essential to the continued progress of the European peoples—namely, the high degree of evolution of the social disposition through group selection in the long prehistoric or race-making period; a group selection which probably was far more severe and prolonged than the peoples of any other part of the world were subjected to; and which in turn was due probably, as we have seen, to the great diversity of physical surroundings and to the comparative severity of the climate of Europe, especially of the northerly parts in which the most progressive European race was formed; for these physical conditions generated in the race an innate energy, a capacity for sustained effort.

Without the highly developed social disposition in the mass of their members, primitive societies could not have survived those changes of custom and institution which were essential features of their progress. Without their innate energy, active rivalry and competition, which have been chief factors in social progress, would not have been constant features of the relations of these societies. Still the possession of a highly evolved social disposition by the European peoples does not in itself suffice to account for the continued mental evolution of the leading nations. For not all the European peoples have progressed; and, of those that have progressed, some have done so much more effectively than others.

Let us first examine the question—In what has progress primarily consisted? Has it been primarily a progress of the moral or of the intellectual traditions? As I mentioned in an earlier chapter, we have here one of the main points of dispute.

Buckle was the great advocate of the primacy of intellectual development in the sense of increase of natural knowledge. The argument by which he sought to establish the position runs as follows: Progress must have been due to improvement either of moral or of intellectual principles. But moral principles have been almost the same in all ages. “To do good to others; to love your neighbour as yourself; to honour your parents—these and a few others, are the sole essentials of morals; but they have been known for thousands of years, and not one jot or tittle has been added to them by all the sermons, homilies and text-books which moralists and theologians have been able to produce.” On the other hand, knowledge and intellectual principles have made immense strides; hence all progress must have been primarily intellectual rather than moral. Buckle did not deny that there has been some moral progress; rather he insisted upon it as an essential feature of the progress of civilisation; but it has, according to him, consisted only in the more effective operation of unchanging principles, and this more effective operation is secondary to, and due to, intellectual progress.

I think we must agree with Buckle that the increasing store of knowledge and the increased command over nature that comes with it has been the primary condition of the progress of nations. For, since the early middle ages, the moral natures of men and the teaching of Christianity have been the same in all essentials; yet for many centuries there was practically no progress. Kidd himself admitted that progress only set in rapidly about the time of the Reformation. And it is notorious that this progress, including the Reformation itself, was due to the stimulation of the intellect by a number of influences—by the renewed study of classical art and literature, by the discovery of the New World, by the increased intercourse of nations resulting from the improvement of the art of navigation, by the accumulation of wealth and the formation of a powerful middle class. It is clear also that religion, far from having been the sufficient cause or instrument of progress, was largely responsible for the stagnation of the middle ages, through sternly repressing the sceptical spirit and leading off men’s minds from inquiry into natural laws, to the discussion of many topics on which it was impossible to achieve knowledge and which were necessarily barren of results making for human progress. Nevertheless the Christian religion has in the long run co-operated in forwarding the mental evolution of the European peoples in an important manner which we must briefly consider later—namely, through its effects upon social organisation.

Without raising the question of the natural or supernatural origin of religion or of any particular religion, we may say that from the point of view of national life, a religion is essentially a system of supernatural sanctions for social conduct, for conduct conforming to the moral code of the society, and especially for customs regulating the family and the relations of the sexes, on which, more than on anything else, social stability depends. It is, thus, the great conservative agency; for it enforces the observance of custom by a system of rewards and punishments; in the earlier stages of society, especially by punishments. It is essentially intolerant of change of custom or belief; and even the Christian religion has exemplified this principle in the terrible persecutions and innumerable wars for which it has been responsible.

The great function and tendency of any religion, once established among a people, is to preserve intact the current moral code and to secure conformity to it. Nevertheless, some religions are less prohibitive of progress than others; and, when such a religion replaces a more restrictive one, an important condition of progress is realised. But, in so far as progress is then favoured, this is not due to the changed operations of the religious emotions and sentiments; it is due to the great religious teachers who have succeeded in breaking down the bonds imposed by the more primitive religion, and so have given freer play to the intellectual faculties; the improvements of religious systems have been negative or permissive conditions of progress, rather than its effective cause.

Progress has, then, always resulted primarily from the gains made by the intellect and added to the intellectual tradition, that is to say, from the progress of knowledge. Nevertheless, the free play of the intellect is always a danger to society, for the reason that the customs and moral code of a society, however imperfect and sanctioned by a religion however narrow, are yet the bonds by which alone it can be held together; to their influence has been largely due in every age the subordination by the members of a society of their individual egoistic ends to the welfare of the society as a whole.
