The saving of energy is another form of the question of continuity of work. The ideal of work—as varied as possible, and as interesting as possible—being the joy of life and the greatest good, is an aim hardly yet grasped by more than a very few persons. To the majority, work is a hateful thing, to be done solely in order to get means for enjoyment in some other way. This essentially savage and uncultivated ideal needs to be steadily rooted out by the better adaptation of work to the individual. An education which started by cultivating the natural interests, using them for mental development, and only superadding what further knowledge was really requisite for life, would greatly help to eradicate the false and low idea of work which prevails. There is a common feeling that business cannot be interesting in itself; but there are few, if any, businesses which if intelligently followed will not yield scope for some real interest of observation and study. The greater application of mind to the work of life will leave far less scope for fruitless amusement and—as a great painter remarked—"there is nothing of interest in life to be compared with work."

To minds which are incapable of continuity of work, or of relaxation by variation of work, mere amusements are needful. Darwin's health prevented more than two hours' work a day, and the flimsiest of novels was his needful relaxation. But the need of amusement for this purpose must be taken as the index of incapacity for continuity—as an unfortunate failure of mental and physical health—as a disastrous defect when it occurs along with great abilities which can only thus work at low speed. The same may be said of athletics; the need of physical exercise outside of work is an index of incapacity for physical health adapted to the work, an unfortunate failure of those who are of defective condition. The idea that no one can be too strong and robust is a wild exaggeration; physical strength needs to be proportioned to the nature of work, and a slender wiry man will do far better for indoor life than a plethoric mass of brawn and muscle which needs much exercise to keep in health. Unlimited robustness is not an absolute good, to be pursued at all costs, or else we should make every schoolboy a Hun, living without shelter, and feeding on flaps of raw meat which form the only saddle of his horse. In brief, the need of athletics shows a weakness of body to be remedied, or a physical over-development unsuited to the person's work in life; it is the mark of unfitness, and the need ceases so soon as a man is adapted to his work. The need of spending any considerable time on amusement is the sign of an incapacity, which has to be removed by strengthening the mind in the individual or in the race. The passion for amusement is the sure evidence of a defective education, which has left the mind incapable of continuity, or bare of interests. An important advance therefore lies in better use of the time which is at present wasted in fruitless action of mind or body; better adaptation and education for the work of life will gradually raise the standard so that this form of waste will be avoided. We do not expect a uniform type of horse to be equally adapted to draught or hunting or racing; and similarly we ought to specialise on different types of men fitted for agriculture, or mechanical work, or office work.

The great subject of the waste by renewal of the population in each generation has an immense variety of aspects; but the essential importance of it is seen when we reflect that about half the labour of the world is swallowed up in this renewal. The burden of production, of rearing, of education, and the waste and loss in the process, exceeds that of any other activity, such as supply of food or shelter, for the adult. Hence any possible saving in this great mass of labour, or reduction of waste, is of the first importance to the individual and the race.

Those who have proposed temporary marriage hardly seem to have considered that one of the most important economies adopted, perhaps dating from a pre-human period, was that of permanent marriage. This saved at a stroke the enormous loss of time and energy in the rivalries of repeated mating. The gain to the race by leaving the members free for continuous work is greater than the loss by reproducing inferior stocks. There is no need for the system to have been intentionally adopted for this purpose; but merely a race which economised the time of repeated mating would soon oust a race in which it was customary. For this reason any fancied reconstruction of society without permanent marriage is entirely futile; even if it could be universal, yet the advantage given to the lazy and emotional type of man above the continuous worker would soon pull down the race. One frequent argument for a more revocable union is the number of divorces effected or desired. But nearly all such are among people whose judgment in any other line of life would certainly not be trusted, and who habitually get into trouble over other communal obligations. To abolish marriage for their benefit would be as reasonable as allowing all debts to be repudiated because such people cannot pay their I.O.U.'s. There is moreover a great gain in permanent marriage when judiciously effected, by the new mental pivot of a sense of permanent ensurance of various of the conditions of life, which liberates the attention of both parties from a large number of points, and leaves each free to concentrate attention on a partial phase of feelings and duties. It is a far higher and a spiritual counterpart of a successful business partnership, where each member trusts the other to manage a different part of the affair. All this mental economy and help would be impossible without permanence.

Another wastage which has been greatly reduced in modern times is that of high birth rate and high death rate. The allusions in mediaeval times show a state much like that now described among the Slovenes, where incessant maternity is only balanced by the reduction of children due to filth, neglect, and bad conditions. The modern ideal of a small family carefully tended is an immense advance, both for the individual life and for the saving of waste. But its benefits should be sought and not commanded. If the neglectful, dirty, and wasteful stocks of low type in our midst let their children die off, it is the only balance to their overgrowth, which would soon outnumber the better class of population. The right end to begin at is by insisting on hard work and tidy living, under penal enactments; the saving of the children may then be left to take care of itself. To begin at the sentimental end, as is now the fashion, is to degrade the whole race by swamping it with the worst stocks.

The line of progress in invention is the remorseless "scrapping" of poorer machines. The more serious the progress becomes, the more scrapping needs to be done. We must not be surprised then if a sign of human progress of mind and body should be the large number of inefficients who are thrown out of work on the scrap heap of society.

In another direction advance has been made by general lengthening of the stages of life. The early marriage and early deaths of past times brought the cost of renewal at every twenty years, which was a much severer tax on the community than renewal in thirty or forty years. There is probably also a great benefit in the higher development of parents before each generation. It is well recognised how the later children of a family are more able, and of a more finished quality than the earlier; great examples of such a view in older literature being Joseph and David, and in our own history, Alfred. The longer growth of mind before each generation appears to be a great gain of advance for the race. Among the lower races, by far the most advanced are those like the Zulu, which have a long period of hard training and active life before settling down to family duties.

The often debated problem dealing with the human refuse of bad stocks is one which presses most on an advanced civilisation. We will not do like the Christian Norseman, when he put the ne'er-do-weel family into a wide grave in the churchyard, and wiped his hands of them. We will not even leave them to exterminate themselves by their own follies, vices, and ignorance. But if the state takes up the burden of such wastrels it must have an entire control of them. Responsibility without rule is worse than rule without responsibility. The only safe course is a rigorous enforcement of parental duties; with the alternative of penal servitude in state workshops, the mother and children together, the father elsewhere. There is no middle course, of semi-maintenance by school meals, which will not injure the children by their being correspondingly neglected at home, injure the parents by lowering the spur of necessity to work, and injure the state by flooding it with the worst types.

Much more drastic treatment of the unfit has been advocated, as by Dr. Rentoul. In a future period of civilisation a logical course of treatment might have a chance of adoption; but in our age any serious changes of the habits of thought and action will not be tolerated, unless brought about very gradually under small influences, such as we have noticed as acting through taxation. What we need is to try to give effect to the gospel of giving to him that hath, and taking away from him that hath not. The most likely opening for such a line of advance would be giving partial state maintenance to the best stocks, so as to ensure large returns from them, and taxing down the worst stocks—exactly the opposite course to the present craze. Let us try to realise if there be a practical system for this advance.
