It is clear that the progress of the individual and the world alike depends upon the quickening of ideas. All civilisation, all law, all order, all controlled and purposeful life, will be seen to depend on these ideas and emotions. The growing conception of the right of every individual to live in some degree of comfort and security is nothing but the taking shape of these ideas and emotions; for the end of all civilisation is to ensure that there shall be freedom for all from debasing and degrading conditions, and that is perhaps as far as we have hitherto advanced; but the further end in sight is to set all men and women free to some extent from hopeless drudgery, to give them leisure, to provide them with tastes and interests; and further still, to contrive, if possible, that human beings shall not be born into the world of tainted parentage, and thus to stamp out the tyranny of disease and imbecility and criminal instinct. More and more does it become clear that all the off-scourings and failures of civilisation are the outcome of diseased brains and nerves, and that self-control and vigour are the results of nature rather than nurture. All this is now steadily in sight. The aim is personal freedom, the freedom which shall end where another's freedom begins; but we recognise now that it is no use legislating for social and political freedom, if we allow the morally deficient to beget offspring for whom moral freedom is an impossibility. And perhaps the best hope of the race lies in firmly facing this problem.
