The parallel existing between the Sicilian and Languedocian civilizations in origin, in progress, in thought, in education, in skepticism, in the repudiation of ecclesiastical interference, is continued even in the date and the method of their extirpation. Both reached their climax during the pontificate of Innocent III., the exemplar of Papal autocracy, the ruthless foe of religious freedom, the evil genius of the thirteenth century. Each was destroyed by a crusade which under the mask of piety appealed to the most sordid impulses and degrading instincts of humanity. Both were followed by conflicts, seditions, and persecutions which endured for centuries. But the fires, while apparently quenched, still smouldered under the ashes of their victims. The principles advocated by philosophical thinkers at the courts of Raymond and Frederick formed the basis of the creeds of Lollard, Huguenot, Puritan. All of the blessings of civil and religious liberty now enjoyed by the enlightened nations of the earth, all of the wonderful mechanical contrivances which lighten toil, diminish suffering, facilitate communication, encourage commerce, promote manufactures, and conduce to the general happiness of the human race, are indirectly derived from the impulse given to philosophical inquiry and scientific progress by the Norman kings of Sicily, the Emperor Frederick II., and the Counts of Provence, animated by the spirit and emulous of the achievements of Arab civilization. These inestimable benefits are inseparable from the innate right of every individual to freely exercise and profit by his mental faculties. That right the Church has always denied as subversive of her alleged prescriptive title to universal sovereignty over the opinions of mankind. In Europe it was first publicly asserted upon the banks of the Guadalquivir, and the advantages its untrammelled practice affords the present generation are a priceless legacy of the founders of the Moslem empire in Spain.
