As bearing on the development and propaganda of the new ideas, the existence of a new intellectual class, rendered possible by the new method of exchange through money (as opposed to that of barter), which for a generation past had been in full swing in the larger towns, must not be forgotten. Formerly land had been the essential condition of livelihood; now it was no longer so. The "universal equivalent," money, conjoined with the printing press, was rendering a literary class proper, for the first time, possible. In the same way the teacher, physician, and the small lawyer were enabled to subsist as followers of independent professions, apart from the special service of the Church or as part of the court-retinue of some feudal potentate. To these we must add a fresh and very important section of the intellectual class which also now for the first time acquired an independent existence--to wit, that of the public official or functionary. This change, although only one of many, is itself specially striking as indicating the transition from the barbaric civilization of the Middle Ages to the beginnings of the civilization of the modern world. We have, in short, before us, as already remarked, a period in which the Middle Ages, whilst still dominant, have their force visibly sapped by the growth of a new life. To sum up the chief features of this new life: Industrially, we have the decline of the old system of production in the countryside in which each manor or, at least, each district, was for the most part self-sufficing and self-supporting, where production was almost entirely for immediate use, and only the surplus was exchanged, and where such exchange as existed took place exclusively under the form of barter. In place of this, we find now something more than the beginnings of a national-market and distinct traces of that of a world-market. In the towns the change was even still more marked. Here we have a sudden and hothouse-like development of the influence of money. The guild-system, originally designed for associations of craftsmen, for which the chief object was the man and the work, and not the mere acquirement of profit, was changing its character. The guilds were becoming close corporations of privileged capitalists, while a commercial capitalism, as already indicated, was raising its head in all the larger centres. In consequence of this state of things, the rapid development of the towns and of commerce, national and international, and the economic backwardness of the country-side, a landless proletariat was being formed, which meant on the one hand an enormous increase in mendicancy of all kinds, and on the other the creation of a permanent class of only casually-employed persons, whom the towns absorbed indeed, but for the most part with a new form of citizenship involving only the bare right of residence within the walls. Similar social phenomena were, of course, manifesting
