There is only one reason why all grown-up people do not play with toys; and it is a fair reason. The reason is that playing with toys takes so very much more time and trouble than anything else. Playing as children mean playing is the most serious thing in the world; and as soon as we have small duties or small sorrows we have to abandon to some extent so enormous and ambitious a plan of life. We have enough strength for politics and commerce and art and philosophy; we have not enough strength for play. This is a truth which every one will recognize who, as a child, has ever played with anything at all; any one who has played with bricks, any one who has played with dolls, any one who has played with tin soldiers. My journalistic work, which earns money, is not pursued with such awful persistency as that work which earned nothing. ..... Take the case of bricks. If you publish a book to-morrow in twelve volumes (it would be just like you) on “The Theory and Practice of European Architecture,” your work may be laborious, but it is fundamentally frivolous. It is not serious as the work of a child piling one brick on the other is serious; for the simple reason that if your book is a bad book no one will ever be able ultimately and entirely to prove to you that it is a bad book. Whereas if his balance of bricks is a bad balance of bricks, it will simply tumble down. And if I know anything of children, he will set to work solemnly and sadly to build it up again. Whereas, if I know anything of authors, nothing would induce you to write your book again, or even to think of it again if you could help it. Take the case of dolls. It is much easier to care for an educational cause than to care for a doll. It is as easy to write an article on education as to write an article on toffee or tramcars or anything else. But it is almost as difficult to look after a doll as to look after a child. The little girls that I meet in the little streets of Battersea worship their dolls in a way that reminds one not so much of play as idolatry. In some cases the love and care of the artistic symbol has actually become more important than the human reality which it was, I suppose, originally meant to symbolize. I remember a Battersea little girl who wheeled her large baby sister stuffed into a doll’s perambulator. When questioned on this course of conduct, she replied: “I haven’t got a dolly, and Baby is pretending to be my dolly.” Nature was indeed imitating art. First a doll had been a substitute for a child; afterwards a child was a mere substitute for a doll. But that opens other matters; the point is here that such devotion takes up most of the brain and most of the life; much as if it were really the thing which it is supposed to symbolize. The point is that the man writing on motherhood is merely an educationalist; the child playing with a doll is a mother.
