With the extension of democratic rights in the first half of the nineteenth century and the ensuing decline of the Federalist establishment, a new conception of education began to emerge. Education was no longer a confirmation of a pre-existing status, but an instrument in the acquisition of higher status. For a new generation of upwardly mobile students, the goal of education was not to prepare them to live comfortably in the world into which they had been born, but to teach them new virtues and skills that would propel them into a different and better world. Education became training; and the student was no longer the gentleman-in-waiting, but the journeyman apprentice for-upward mobility.In the nineteenth, century a college education began to be seen as a way to get ahead in the world. The founding of the land-grant colleges opened the doors of higher education to poor but aspiring boys from non-Anglo-Saxon, working-class and lower-middle-class backgrounds. The myth of the poor boy who worked his way through college to success drew millions of poor boys to the new campuses, And with this shift, education became more vocational: its object was the acquisition of practical skills and useful information.For the gentleman-in-waiting, virtue consisted above all in grace and style, in doing well what was appropriate to his position; education was merely a way of acquiring polish. And vice was manifested in gracelessness, awkwardness, in behaving inappropriately, discourteously, or ostentatiously. For the apprentice, however, virtue was evidenced in success through hard work. The requisite qualities of character were not grace or style, but drive, determination, and a sharp eye for opportunity. While casual liberality and even prodigality characterized the gentleman, frugality, thrift, and self-control came to distinguish the new apprentice.

Perhaps only a small boy training to be a wizard at the Hog warts school of magic could cast a spell so powerful as to create the biggest book launch ever. Wherever in the world the clock strikes midnight on June 20th, his followers will flock to get their paws on one of more than 10m copies of’’Harry Potter and the Order of the Phoenix". Bookshops will open in the middle of the night and delivery firms are drafting in extra staff and bleater trucks. Relaxed toys, games, DVDs and other merchandise will be everywhere. There will be no escaping Pottennania.Yet Mr. Potter’s world is a curious one, in which things are often not what they appear. While an excitable media (hereby including The Economist, happy to support such a fine example of globalization) is helping to hype the launch of J.K. Rowling's fifth novel about the most adventurous thing that the publishers (Scholastic in America and Britain's Bloomsbury in English elsewhere) have organized is a reading by Ms. Rowling in London's Royal Albert Hail, to be broadcast as a Jive webcast. Hollywood, which owns everything else to do with Harry Potter, says it is doing ev
