Political and social progress, though less astonishing, was substantial. In 1830 England, nominally a monarchy, was in reality a plutocracy of about a hundred thousand men--landed nobles, gentry, and wealthy merchants--whose privileges dated back to fifteenth century conditions. The first Reform Bill, of 1832, forced on Parliament by popular pressure, extended the right of voting to men of the 'middle class,' and the subsequent bills of 1867 and 1885 made it universal for men. Meanwhile the House of Commons slowly asserted itself against the hereditary House of Lords, and thus England became perhaps the most truly democratic of the great nations of the world. At the beginning of the period the social condition of the great body of the population was extremely bad. Laborers in factories and mines and on farms were largely in a state of virtual though not nominal slavery, living, many of them, in unspeakable moral and physical conditions. Little by little improvement came, partly by the passage of laws, partly by the growth of trades-unions. The substitution in the middle of the century of free-trade for protection through the passage of the 'Corn-Laws' afforded much relief by lowering the price of food. Socialism, taking shape as a definite movement in the middle of the century, became one to be reckoned with before its close, though the majority of the more well-to-do classes failed to understand even then the growing necessity for far-reaching economic and social changes. Humanitarian consciousness, however, gained greatly during the period. The middle and upper classes awoke to some extent to their duty to the poor, and sympathetic benevolent effort, both organized and informal, increased very largely in amount and intelligence. Popular education, too, which in 1830 had no connection with the State and was in every respect very incomplete, was developed and finally made compulsory as regards the rudiments. Still more permanently significant, perhaps, was the transformation of the former conceptions of the nature and meaning of the world and life, through the discoveries of science. Geology and astronomy now gradually compelled all thinking people to realize the unthinkable duration of the cosmic processes and the comparative littleness of our earth in the vast extent of the universe. Absolutely revolutionary for almost all lines if thought was the gradual adoption by almost all thinkers of the theory of Evolution, which, partly formulated by Lamarck early in the century, received definite statement in 1859 in Charles Darwin's 'Origin of Species.' The great modification in the externals of religious belief thus brought about was confirmed also by the growth of the science of historical criticism.
