There was in these utterances an irresistible attraction to minds prone to mystic exaltation. Even the orthodox Cæsarius of Heisterbach argues that much is permitted to the saints which is forbidden to sinners; where is the Spirit of God, there is liberty--have charity, and do what thou pleasest.[359] When the fatal word had once been spoken, it could not be hushed to silence, and, in spite of the most persistent and unsparing efforts of repression, these dangerous heights of superhuman spirituality continued to be the goal of men dissatisfied with the limitations of frail humanity, down to the time of Molinos and the Illuminati, and the influence of the doctrine is to be traced in the reveries of Madame Guyon and the Quietists. Yet the Amaurian heresy was speedily crushed in its place of origin. In his proselyting zeal, Guillaume the goldsmith, in 1210, approached a certain Maître Raoul de Nemours, who feigned readiness of conviction, and reported the matter to Pierre, Bishop of Paris, and Maître Robert de Curzon, the papal supervisor of preaching in France. By their advice he pretended conversion and accompanied the Amaurians on a missionary tour which lasted for three months and extended as far as Langres. We learn something of the habits of the sectaries when we are told that to keep up the deception he would pretend to be wrapped in ecstasy, with face upturned to heaven, and on recovering himself would relate the visions which had been vouchsafed to him, though he successfully evaded the requests that he should preach the new doctrines in public. When fully informed as to all details, he communicated with the authorities, and arrests were made. A council of bishops was convened in Paris which found no difficulty in condemning all concerned; those who were in orders were degraded, and they were all handed over to the secular authorities. There were as yet no laws defining the punishment of heresy, so their fate was postponed until the return of the king, who was then absent. The result was that four of the leaders were imprisoned for life and ten were burned, who met their fate with unshrinking calmness. The simple folk of both sexes who had been seduced into following them were mercifully spared. A few executions took place elsewhere, such as that of one of the heresiarchs, Maître Godin, who was tried and burned at Amiens; the remains of Amauri were exhumed and exposed to the dogs, after which his bones were scattered in the fields; the writings of the enthusiasts were forbidden to be read; the study of natural science in the university was suspended for three years, and the works of Aristotle, which had given rise to the heresy, were publicly burned.[360]
