of Languedoc, and, at a later period, of Epicureanism in the Ghibelline circles of Florentine society; while, conversely, when the Ciompi or poorer artisans of Florence rose in revolt against the rich traders, one of the first demands made by the successful insurgents was, that a preaching friar should be sent to give them religious instruction. At a still later period, the same opposition of intellectual interests continues to be defined by the same social divisions. Two distinct currents of thought co-operated to bring about the Protestant Reformation. One, which was religious and reactionary, proceeded from the people. The other, which was secularising, scholarly, and scientific, represented the tendencies of the upper classes and of those who looked to them for encouragement and support. Throughout the sixteenth and seventeenth centuries, many noble names are to be found among the champions of reason; and while speculative liberty is associated with the ascendency of the aristocratic party, superstition and intolerance are associated with the triumph of the people, whether under the form of a democracy or of a levelling despotism. So, also, the great emancipating movement of the eighteenth century was fostered by the descendants of the Crusaders, and, until after the Revolution, met with no response among the bourgeoisie or the people; indeed the reaction in favour of supernaturalism was begun by a child of the people, Rousseau. All this, as we have already observed, has been reversed in more recent times; but the facts quoted are enough to prove how natural it was that in the ancient world decay of class privileges should be equivalent to a strengthening of the influences which made for supernaturalism and against enlightened criticism.
