The succeeding chapters of this book will, it is hoped, supply some evidence of the concrete reality of progress, as well as of the tendency to greater coherence and purity in the ideal itself. It would have been easy to accumulate evidence; some sides of life are hardly touched on at all. The collective and the intellectual sides are fully dealt with both in this and in the volume on _The Unity of Western Civilization_. But if we make our survey over a sufficient space, coming down especially to our own days, our conclusion as to the advance made in the physical and moral well-being of mankind, will be hardly less emphatic. Our average lives are longer and continue to lengthen, and they are unquestionably spent with far less physical suffering than was generally the case at any previous period. We are bound to give full weight to this, however much we rightly deplore the deadening effect of monotonous and mechanical toil on so large a part of the population. And even for these the opportunities for a free and improving life are amazingly enlarged. We groan and chafe at what remains to be done because of the unexampled size of the modern industrial populations with which we have to deal. But we know in some points very definitely what we want, and we are now all persuaded with John Stuart Mill that the remedy is in our own hands, 'that all the great sources of human suffering are in a great degree, many of them entirely, conquerable by human care and effort.' This conviction is perhaps the greatest step of all that we have gained. In morality some pertinent and necessary questions are raised in Chap. VI, but the general progress would be doubted by very few who have had the opportunity of comparing the evidence as to any previous state of morals, say in the Middle Ages or in the Elizabethan age--the crown of the Renascence in England--with that of the present day. The capital advance in morality, which by itself would be sufficient to justify our thesis, is the increase in the consciousness and the obligation of the 'common weal', that conception of which Government, increasingly better organized, is the most striking practical realization. It has its drawback in the spread of what we feel as a debasing 'vulgarity', but the general balance is overwhelmingly on the side of good. And in all such discussions we are apt to allow far too little weight to the change which the New World, and especially the United States, has brought about. In matters of personal prosperity and a high general standard of intellectual and moral competence, what has been achieved there would outweigh a good deal of our Old World defects when we come to drawing up a world's balance-sheet.
