Public schools are particularly important in America, where presidential and congressional elections are apt to turn on financial issues which can scarcely be understood by men not thoroughly educated. Spencer's objections apply more closely to the European system, that of centralisation of management, than to the American. It is well to know also that he was misled by a hasty reference, perhaps by some assistant, to an English statistician named Fletcher. This high authority did admit, in 1849, that he found "a superficial evidence against instruction." He went on, however, to say much which is not mentioned in _Social Statics_, and which proved the evidence to be only superficial. By classifying crimes according to enormity, he showed that the worst were most frequent in the least educated districts. He also discovered that those counties in England where ability to sign the marriage register was most common were most free from paupers, dangerous criminals, and illegitimate children. "The conclusion is therefore irresistible," says Fletcher, "that education is essential to the security of modern society." Most of the other testimony brought forward in _Social Statics_ is invalidated by Fletcher's method; and Spencer added nothing in the second edition to the insufficient statements in the first. British education has improved greatly in both quality and quantity since 1876; but the prisons of England and Wales had only two-thirds as many inmates in 1890 as in 1878, and only one-half as large a part of the population. The most dangerous prisoners were only one-third as numerous in 1890 and 1891 as forty-five years earlier; and the percentage of forgers only one-tenth as great as in 1857. We ought further to remember the almost complete unanimity of opinion in favour of free education wherever it is universal.
