The change is affecting the meaning of marriage, since we are becoming inclined to suppose that man and woman are not simply male and female. Human individuality is given a new value; and there is no telling yet what the new attitude may involve in lessening the friction due to primitive and obsolete tradition or in making society more reasonable and civilized. The source of the change is undoubtedly an enthusiasm which has been influenced by men and women of all nations. Ibsen has a place in the history of social transformation. And besides, the contact between nations has made it possible for the freer position of women in one group to affect the domestic slavery of another. In the position of children, also, an immense change is proceeding. We cannot fail to call it social reform, that the child should be given so much more definite a place in the social organism. Aristotle thought woman was a mistake of nature's in the attempt to make man; and nearly all philosophers have treated children as if they ought to be rather ashamed of themselves for not being grown up. I speak of philosophers in the wide sense of the term, for I do not think the metaphysicians knew that there was such a thing as a child in the universe. However that may be, we can hardly believe that as late as the nineteenth century parents really imagined that they knew what was good for their children. In our more sceptical age, children have generally to be careful not to allow their parents to read certain books, and in every well brought up family, it is thought that parents should be seen and not heard. A social change has occurred in the comparative importance we assign to childhood and age. Thirdly, there is gradually coming about a transformation of social castes. One must speak carefully; for in the West we are supposed not to have castes. There is, however, an uncomfortable feeling that society is not one, that the two cities which Plato said would divide and destroy the true city of men are now established--the rich and the poor. I do not mean those with L3,000 a year, and those with L160 a year. It is not a question for the Exchequer. I mean that great numbers in all 'civilized' nations are ill-fed and ill-clothed from birth, and die prematurely. To perceive it is to desire action which perhaps no state can perform. But that we perceive it is something. Read the complacent rhymes of Lord Tennyson about 'freedom slowly broadening down' and then turn to contemporary literature, to Jean Richepin or John Galsworthy, and you will acknowledge that a common ideal of social reform has come into existence. We are at least restless in face of a social organization which wastes humanity during long years of peace almost as completely, though not so recklessly, as during a few months of war.
