in considering or designing any kind of work the first and most essential condition is the quality of material that has to be used. "you cannot make a silk purse out of a sow's ear." and what is true materially is true also mentally; the character of a people is the essential basis of all their institutions and government. if we intend to consider what improvements are possible, or what degradations may occur, we must treat the matter entirely as a question of character. "for forms of government let fools contest, whate'er is best administered is best," and the administration depends upon the character of the people. we see on all sides that races of a low character necessarily pass, by the force of events, under the domination of other races who have a higher or stronger character. it is the quality of the race which is the most essential and determining factor in its history. that every nation has the kind of government which it deserves, is an old remark, which implies that its character determines its fate.2 the diligent but cautious scot; the slovenly slovene; the self-deceived gaul; the tediously complete and logical german; these all show the manner in which their administration is the product of the individual character. further, happiness is essentially dependent upon character, and is—by comparison—determined by character alone, almost apart from external circumstances.

it is therefore a matter of the first importance to consider how character is produced or modified. possibly to some it may appear presumptuous to apply to the mind those natural laws which it is now generally agreed apply to bodily development. yet even the probabilities of chance distribution may be shown to apply to the varieties of mind; both by rough observation in general, and also by a test case quantitatively applied (see religion and conscience in ancient egypt). a feeling against this treatment of the mind by material law is based on the idea that it implies an absence of free-will. but, to take an illustration, a railway company may be certain of carrying very closely the same number of passengers each day, without in the least embarrassing the free-will of any passenger as to whether or no he will travel. let us notice, therefore, how the various principles of physical modification are applicable also to mental change. whether it may be that changes take place by the inheritance of acquired characteristics, or whether they occur solely by accidental variation which proves beneficial, is a much debated question which is not requisite for us to settle here. it is agreed that in the physical life of all animals it may be seen that: (1) favourable variations give a3 determining advantage to one individual over another, or to one more than another against a common enemy; (2) useful variations tend to be maintained in successive generations; (3) artificial conditions tend to produce variation; (4) greater variability accompanies unusual developments; (5) growth is directed and encouraged by use; and (6), as the total activity is limited, therefore disuse causes atrophy and degradation, by favouring of parts more used. to these follows the important corollary (7): variation being only of benefit where there is competition in which it gives an advantage, its improvements will cease to be maintained in the absence of competition; it is only competition which makes improved variations permanent. for instance, if there were no carnivora the swifter deer would not have found their pace a benefit, and there would be no sufficient cause for their attaining their present swiftness. in place of looking on selection as merely a struggle we must look on it as the sole physical means of permanent elevation, the motor which has raised every species to its present point of ability.

to these principles common to all organic nature must be added another which is almost peculiar to man alone. we often hear that environment is the determinant of the nature of both animals and man. but the distinctive quality of man is the subjection of the environment to the ruling faculty; man is not necessarily conditioned by his environment, but a direct measure of his civilisation is the extent to which he creates his own conditions. other communal animals, as the ant, the bee, or the beaver, have anticipated this to some extent; but in man alone can4 the ruling faculty rise to an entire reversal of almost every condition of environment.

the mental equivalents of these physical modifications are obviously true in common experience and in historical example.

(1) that a favourable variation of mind gives a determining advantage needs no illustration, as every sharp and able man of business has shown this in all ages.

(2) that mental qualities are inherited has been pretty generally recognised, and the work of galton on hereditary genius has enforced this by statistical example. but the historical consequences have not been sufficiently noticed; for it is obviously possible by selective action to increase or diminish not only the bodily activity but also the mental ability seen in the whole community. the series of proscriptions of all the leading men of rome, alternately on one side and then on the other, from marius down to octavius, was so disastrous a drain of political ability, that only the julian family was left; and there was never an able emperor of roman ancestry after that line was extinct. the expulsion of the huguenots from france drained it of the active middle class minds, and left the great gap in the continuity of sympathy which made the revolution possible. the later expulsion or extermination also of the active upper class minds drained that land of nearly all the hereditary ability of the race: the consequence has been to leave at the present day a nation of mediocrities, among whom there is but a fraction of the genius seen in germany and england on either side of it. almost every leading name is that of a foreigner, as for5 instance waddington, zurlinden, eiffel, reinach, rothschild, gambetta, maspero. another very important consideration is that sporadic ability is not inherited in the same manner as long continued family ability. not a single roman emperor who rose solely from his individual powers left a worthy and capable son. the gordians were a good senatorial family, and ran through three generations on the throne. in england the same thing is seen. the main source of new men of ability is from sturdy puritan or quaker stocks that have long practised self-denial and hard work; old families with long traditions of public service continue usually on the same line of ability; but the nouveaux riches who have sprung forward on some lucky speculation or trade enterprise usually go hopelessly to pieces in the next generation. the longer a useful type has been maintained the more stable it is.

(3) that artificial conditions tend to produce variation is obvious in every civilisation. the more intense is the artificiality of life, the greater are the extremes of ability and incompetence, of riches and poverty, accompanying it. it is often a problem to kind hearts that there should be such misery and degradation side by side with the ease and welfare of civilisation. the answer is that it is inevitable, because the very same artificiality which gives scope to the capable to rise, equally gives scope for the incapable to fall. every chance, every opening, every benefit attainable by exertion, is a means of advance to him who uses it; but it is accompanied by equal chances of failure, equal openings to loss, equal injuries resulting from sloth, which are the6 equally sure means of degradation for those who have not the wit or energy to avoid them. the "submerged tenth" is the inevitable complement of the leading tenth.

(4) greater variability of mind accompanies unusual development; this is seen in the great outbursts of mental activity which have occurred along with external expansion in the times of elizabeth and of victoria. or in earlier times the growth of greek literature following the periclean expansion, or of roman literature with the augustan settlement of the world.

(5) mental growth is directed and encouraged by use. this fact is so obvious that it is proverbial, as in the saying, "the mind grows by what it feeds upon." all mental training and teaching recognise this, but it is true in later life as well as in youth. it is well known how in the least civilised races small children are as advanced—or more so—than in higher races. the australian is said to come to a standstill at ten or twelve years old. the egyptian seldom advances mentally after sixteen. a low-class englishman does not improve after twenty or so. a capable man will continue to expand till thirty or forty. and the man of the greatest capacity will continue to grow mentally, and assimilate new lines of thought, until seventy or eighty.

thus the greater the power of use and the activity of the mind, the longer will it continue to grow. this may well be regarded as one of the main tests of a great mind; and it is strictly in accord with the system of the well-known embryonic changes passing from lower to higher stages, and continuing to grow7 in development into higher and higher types. the savage ceased to grow mentally even while in childhood; the sage continues the expansion of mind to extreme old age.

(6) disuse of mind causes atrophy and degradation. this principle is one of the most important of all in its practical bearings. the familiar figure of the later merovings, the rois fainéants, is an historical example: freed from all necessity of thought by the assiduity of the mayors of the palace, the family mind atrophied further in each generation, until the king became a puppet without volition in royal affairs. the same working may be seen in the upper classes of many countries, where the spur of the necessity of action ceases. within a century of the cessation of the moorish wars the chivalry of spain began to atrophy; the same was seen in a century after the cessation of civil war in france. in england the strong tradition of training for the public careers in the civil and military services and parliament, has saved the upper classes more than elsewhere. but a rich family without active interests almost always shows atrophy of mind. there is a fine saying of mencius, "those whom god destines for some great part, he first chastens by suffering and toil." the same tendency to atrophy is equally seen in the lower classes, when the necessity of self-help is removed. and many of the modern movements have been of a degrading tendency, leading to the holding back of the capable and the artificial help of the incapable. it is obvious that if persons have retrograded and got into difficulties, they are presumably less capable than those around them. if then they are8 relieved independently of their own exertions, their incapacity is fostered and they retrograde still further. to compensate them for their incapacity by relief works, by farm colonies, by outdoor relief doles, by maintenance of their children, will inevitably lead to further atrophy of mind. the doctrine of equality of wages in a trade is a double injury, it encourages the most incapable man that can possibly squeeze into the trade, and it discourages the capable man who is worth far more than the average. it must tend to drive capable men out of the trades which they might have raised by their example and stimulus, into other lines where capacity can still earn its value. the mental atrophy that has come over ordinary workmen is appalling, at least in the region of london. in case after case, the common sense and intelligence seems to have been entirely lost, and the grossest blunders will be made by well-paid men; and it is safe to say that in most business a really capable and active man can do from three to six times as much as the average workman, beside avoiding the loss of time by mistakes. in short a certified ease of conditions, and absence of direct penalties of incapacity, has atrophied the ordinary working mind to a point which is dangerously low in comparison with that of other races. the remedy lies in training the incapable by a stern discipline of gradually teaching them the maximum that they can perform in the day, with good direction and avoidance of bad conditions. after a couple of years of such intensive training they should be drafted into ordinary factories, with the warning that if they fall out of work again, another year's compulsory hard training will be the result.

in another way this atrophy of mind may be seen and felt as a temporary condition by members of boards and committees. what is everyone's business is nobody's business; and when each person feels that he is not personally responsible, a numbness and inaction ensues which is characteristic of such bodies. men, any one of whom would act sensibly when alone, will succumb to the paralysing sense that they need not think because nine other men are doing so, and the results are well known as characterising these assemblies which have "neither a body to be kicked nor a soul to be damned." there are very few public bodies which are not really dependent on the individual thought and design of one person, criticised and amended by the collateral views of others. in short, all action and rule must be personal and not corporate, however much the person may be checked and controlled by general opinion of the public, or of a restricted body. without personal initiative atrophy is the result.

another great theatre of mental atrophy is officialism, where a man is bound to follow certain rules and routine rather than to think. a german has remarked to me that a man who is perfectly reasonable and intelligent in private life becomes quite foolish as soon as he enters his office. this constant result is the strongest reason for not extending official control of affairs needlessly, or the management of public work by officials. private enterprise will always be more effective than an official system, because it is solely the result of individual initiative. the enormous monopolies of railways in england are on the whole far more beneficial to the public than the state10 railways of other countries. the evils of corporate monopoly, checked by law and supervision of the board of trade, are less than the evil of stagnation by official atrophy. in the republic of france the principal line runs its best trains slower than, and at three times the cost of, the best trains on great english lines.

(7) it is only competition which makes permanent the improved mental variations which occur. the evils of competition in physical things almost disappear in the mental field; and, unless misused as in a foolishly designed examination, there seems an unmixed benefit from unlimited competition of mind. it is only by such competition that higher types of ability have been established in the past, and it is to such that we must look for future improvement. it is true that in various directions we find a dislike of competition; but that is the surest sign that it is effective, and therefore beneficial to the whole body.

we see then that each of those principles which rule in physical modification is equally true of mental modification.

but though the modes of mental variation may be fairly clear, we must not be carried away by the view that therefore great changes in man are to be expected. the effects of various conditions upon the body are tolerably familiar, yet the average form of man has varied extraordinarily little during ten thousand years. the highest type of ancient man differs almost inappreciably from the highest type of modern man, certainly by not a tenth of the difference that may be seen between different types at present. it may be practically said that man is at a standstill11 in physical development. sanitary improvements and better feeding may do great things, but they leave the essential form and constitution unaltered. the same is true of mind. when we become familiar with details of early ages nothing is more astonishing than to see how unaltered the mind of man is in its essentials. in tales and maxims six thousand years old we see not only the common stock of primary instincts, but also the finesse of conduct in public life, the modes of ensuring respect in dealing with superiors and inferiors, the attention to very varied elements of character, and a fine suavity and kindliness pervading the whole. there is not a single class or a single public body at present that practically stands as high as the ideal of two hundred generations ago. and when we look at the material civilisation we see still farther back the appreciation of qualities of work which only a very small proportion of mankind care for now. the overwhelming zeal for minute accuracy was as perfect a mental state at 4700 b.c. as it is in a royal society paper of our day. the subject and the method have changed; but the mental attitude is the same in a man who demanded, and in those who executed, beautifully true plane surfaces, and long measurements exact to far within the variation of size caused by a hot or a cold day, and the men now who triangulate a continent and measure the world. the mind is the same, only the stock-in-trade of it has increased. at the beginning of history the palaces were adorned with table services cut in the hardest and most beautiful stones, exquisitely formed and polished; and such homes were assuredly inhabited by men whose tastes12 and artistic sense were closely the same as the best of ours, and who would, like us, have revolted at most of the products of the present time. not only was there the body of highly skilled and intelligent men to do such work, but there must have been a widely spread standard of taste demanding this exquisite work as an aesthetic pleasure. the nature of mind is unchanged, its motives, its feelings, its sense of life; only in knowledge and the applications of it do we differ from the earliest civilisation that we can trace.

it is, therefore, quite unreal for us to anticipate any change in the essential nature of man in the next few thousand years. the increase of knowledge and its applications will not alter that nature, or the relation of mind to mind. we shall still desire and admire the same things, and be moved by the same impulses; and we may neglect as ignorant dreams all speculations about any essential changes in the motives or constitution of man.
