The remarks I have now made will be sufficient, I hope, to throw some light upon those great questions concerning the relations of intellectual and moral progress which have of late years attracted so large an amount of attention. It has been contended that the historian of human progress should concentrate his attention exclusively on the intellectual elements; for there is no such thing as moral history, morals being essentially stationary, and the rudest barbarians being in this respect as far advanced as ourselves. In opposition to this view, I have maintained that while what may be termed the primal elements of morals are unaltered, there is a perpetual change in the standard which is exacted, and also in the relative value attached to particular virtues, and that these changes constitute one of the most important branches of general history. It has been contended by other writers that, although such changes do take place, and although they play an extremely great part in the world, they must be looked upon as the result of intellectual causes, changes in knowledge producing changes in morals. In this view, as we have seen, there is some truth, but it can only, I think, be accepted with great qualification. It is one of the plainest of facts that neither the individuals nor the ages most distinguished for intellectual achievements have been most distinguished for moral excellence, and that a high intellectual and material civilisation has often coexisted with much depravity. In some respects the conditions of intellectual growth are not favourable to moral growth. The agglomeration of men in great cities—which are always the centres of progress and enlightenment—is one of the most important causes of material and intellectual advance: but great towns are the peculiar seed-plots of vice, and it is extremely questionable whether they produce any special and equivalent efflorescence of virtue, for even the social virtues are probably more cultivated in small populations, where men live in more intimate relations. Many of the most splendid outbursts of moral enthusiasm may be traced to an overwhelming force of conviction rarely found in very cultivated minds, which are keenly sensible to possibilities of error, conflicting arguments, and qualifying circumstances. Civilisation has on the whole been more successful in repressing crime than in repressing vice. It is very favourable to the gentler, charitable, and social virtues, and, where slavery does not exist, to the industrial virtues, and it is the especial nurse of the intellectual virtues; but it is in general not equally favourable to the production of self-sacrifice, enthusiasm, reverence, or chastity.
