"However much," says Lea, "we may deprecate the means used for its suppression, and commiserate those who suffered for conscience' sake, we cannot but admit that the cause of orthodoxy was in this case the cause of progress and civilization. Had Catharism become dominant, or even had it been allowed to exist on equal terms, its influence could not have failed to prove disastrous. Its asceticism with regard to commerce between the sexes, if strictly enforced, could only have led to the extinction of the race.... Its condemnation of the visible universe, and of matter in general as the work of Satan rendered sinful all striving after material improvement, and the conscientious belief in such a creed could only lead man back, in time, to his original condition of savagism. It was not only a revolt against the Church, but a renunciation of man's domination over nature."[1] Its growth had to be arrested at any price. Society, in proceeding against it without mercy, was only defending herself against the working of an essentially destructive force. It was a struggle for existence. We must, therefore, deduct from the number of those who are commonly styled the victims of ecclesiastical intolerance, the majority of the heretics executed by the State; for nearly all that were imprisoned or sent to the stake, especially in northern Italy and southern France, were Cathari.[1] [1] Jean Guiraud has proved that the Waldenses, Fraticelli, Hussites, Lollards, etc., attacked society, which acted in self-defense when she put them to death. _La répression de l'hérésie au moyen âge_, in the _Questions d'histoire et d'archéologie Chrétienne_, p. 24 and seq. This important observation has so impressed certain historians, that they have been led to think the Inquisition dealt only with criminals of this sort. "History," says Rodrigo, "has preserved the record of the outrages committed by the heretics of Bulgaria, the Gnostics, and the Manicheans; the death sentence was inflicted only upon criminals who confessed their murders, robberies, and acts of violence. The Albigenses were treated with kindness. The Catholic Church deplores all acts of vengeance, however strong the provocation given by these factious mobs."[1] [1] _Historia verdadera de la Inquisición_, Madrid, 1876, vol. i, p. 176, 177.
