For this is the grand SOCIAL tragedy. It is the tragedy of an unlearned human society; it is the tragedy of a civilization in which grammar, and the relations of sounds and abstract notions to each other have sufficed to absorb the attention of the learned,--a civilization in which the parts of speech, and their relations, have been deeply considered, but one in which the social elements, the parts of life, and their unions, and their prosody, have been left to spontaneity, and empiricism, and all kinds of rude, arbitrary, idiomatical conjunctions, and fortuitous rules; a civilization in which the learning of 'WORDS' is put down by the reporter--invented-- and the learning of 'THINGS'--omitted. And in a movement which was designed to bring the human reason to bear scientifically and artistically upon those questions in which the deepest human interests are involved, the wrong and misery of that social state to which the New Machine, with its new combination of sense and reason, must be applied, had to be fully and elaborately brought out and exhibited. And there was but one language in which the impersonated human misery and wrong,--the speaker for countless hearts, tortured and broken on the rude machinery of unlearned social customs, and lawless social forces, could speak; there was but one tongue in which it could tell its story. For this is the place where science becomes inevitably poetical. That same science which fills our cabinets and herbariums, and chambers of natural history, with mute stones and shells and plants and dead birds and insects--that same science that fills our scientific volumes with coloured pictures true as life itself, and letter-press of prose description--that same science that anatomises the physical frame with microscopic nicety,--in the hand of its master, found in the soul, that which had most need of science; and his 'illustrated book' of it, the book of his experiments in it, comes to us filled with his yet living, 'ever living' _subjects_, and resounding with the tragedy of their complainings.
