From Middlemarch, by George Eliot

Most of us who turn to any subject with love remember some morning or evening hour when we got on a high stool to reach down an untried volume, or sat with parted lips listening to a new talker, or for very lack of books began to listen to the voices within, as the first traceable beginning of our love. Something of that sort happened to Lydgate. He was a quick fellow, and when hot from play, would toss himself in a corner, and in five minutes be deep in any sort of book that he could lay his hands on: if it were Rasselas or Gulliver, so much the better, but Bailey's Dictionary would do, or the Bible with the Apocrypha in it. Something he must read, when he was not riding the pony, or running and hunting, or listening to the talk of men. All this was true of him at ten years of age; he had then read through "Chrysal, or the Adventures of a Guinea," which was neither milk for babes, nor any chalky mixture meant to pass for milk, and it had already occurred to him that books were stuff, and that life was stupid. His school studies had not much modified that opinion, for though he "did" his classics and mathematics, he was not pre-eminent in them. It was said of him, that Lydgate could do anything he liked, but he had certainly not yet liked to do anything remarkable. He was a vigorous animal with a ready understanding, but no spark had yet kindled in him an intellectual passion; knowledge seemed to him a very superficial affair, easily mastered: judging from the conversation of his elders, he had apparently got already more than was necessary for mature life. Probably this was not an exceptional result of expensive teaching at that period of short-waisted coats, and other fashions which have not yet recurred. But, one vacation, a wet day sent him to the small home library to hunt once more for a book which might have some freshness for him: in vain! unless, indeed, he took down a dusty row of volumes with gray-paper backs and dingy labels--the volumes of an old Cyclopaedia which he had never disturbed. It would at least be a novelty to disturb them. They were on the highest shelf, and he stood on a chair to get them down. But he opened the volume which he first took from the shelf: somehow, one is apt to read in a makeshift attitude, just where it might seem inconvenient to do so. The page he opened on was under the head of Anatomy, and the first passage that drew his eyes was on the valves of the heart. He was not much acquainted with valves of any sort, but he knew that valvae were folding-doors, and through this crevice came a sudden light startling him with his first vivid notion of finely adjusted mechanism in the human frame. A liberal education had of course left him free to read the indecent passages in the school classics, but beyond a general sense of secrecy and obscenity in connection with his internal structure, had left his imagination quite unbiassed, so that for anything he knew his brains lay in small bags at his temples, and he had no more thought of representing to himself how his blood circulated than how paper served instead of gold. But the moment of vocation had come, and before he got down from his chair, the world was made new to him by a presentiment of endless processes filling the vast spaces planked out of his sight by that wordy ignorance which he had supposed to be knowledge. From that hour Lydgate felt the growth of an intellectual passion.
