My own belief is that these great ideas like Equality and Justice are things which, like poetry, are born and cannot be made. That a number of earnest people should be thinking about them shows that they are in the air; but the interest felt in them is the sign and not the cause of their increase. I believe that one must go forwards, trying to avoid anything that is consciously harsh or pompous or selfish or base, and the great ideas will take care of themselves.
The two great obvious difficulties which seem to me to lie at the root of all schemes for producing a system of social equality are first the radical inequality of character, temperament, and equipment in human beings. No system can ever hope to be a practical system unless we can eliminate the possibility of children being born, some of them perfectly qualified for life and citizenship, and others hopelessly disqualified. If such differences were the result of environment it would be a remediable thing. But one can have a strong, vigorous, naturally temperate child born and brought up under the meanest and most sordid conditions, and, on the other hand, a thoroughly worthless and detestable person may be the child of high-minded, well-educated people, with every social advantage. My work as a practical educationalist enforced this upon me. One would find a boy, born under circumstances as favourable for the production of virtue and energy as any socialistic system could provide, who was really only fitted for the lowest kind of mechanical work, and whose instincts were utterly gross. Even if the State could practise a kind of refined Mendelism, it would be impossible to guard against the influences of heredity. If one traces back the hereditary influences of a child for ten generations, it will be found that he has upwards of two thousand progenitors, any one of whom may give him a bias.
