[Sidenote: Influence of thought upon the arrangements of society.] Now, along with the literary revival, partly caused by, partly causing it, there had been also a wonderful stirring and uprising in the mind of Europe. The yoke of church authority still pressed heavily on the souls of men; yet some had been found to shake it off, and many more murmured in secret. The tendency was one which shewed itself in various and sometimes apparently opposite directions. The revolt of the Albigenses, the spread of the Cathari and other so-called heretics, the excitement created by the writings of Wickliffe and Huss, witnessed to the fearlessness wherewith it could assail the dominant theology. It was present, however skilfully disguised, among those scholastic doctors who busied themselves with proving by natural reason the dogmas of the Church: for the power which can forge fetters can also break them. It took a form more dangerous because of a more direct application to facts, in the attacks, so often repeated from Arnold of Brescia downwards, upon the wealth and corruptions of the clergy, and above all of the papal court. For the agitation was not merely speculative. There was beginning to be a direct and rational interest in life, a power of applying thought to practical ends, which had not been seen before. Man's life among his fellows was no longer a mere wild beast struggle; man's soul no more, as it had been, the victim of ungoverned passion, whether it was awed by supernatural terrors or captivated by examples of surpassing holiness. Manners were still rude, and governments unsettled; but society was learning to organize itself upon fixed principles; to recognize, however faintly, the value of order, industry, equality; to adapt means to ends, and conceive of the common good as the proper end of its own existence. In a word, Politics had begun to exist, and with them there had appeared the first of a class of persons whom friends and enemies may both, though with different meanings, call ideal politicians; men who, however various have been the doctrines they have held, however impracticable many of the plans they have advanced, have been nevertheless alike in their devotion to the highest interests of humanity, and have frequently been derided as theorists in their own age to be honoured as the prophets and teachers of the next.
