Still, everybody was not like them, and the vices of the clergy explain the innumerable heresies of that day. All of them had a certain success, from those which were simply the outcry of an outraged conscience, like that of the Waldenses, to the most absurd of them all, like that of Eon de l'Etoile. Some of these movements were for great and sacred causes; but we must not let our sympathies be so moved by the persecutions suffered by heretics as to cloud our judgment. It would have been better had Rome triumphed by gentleness, by education and holiness, but unhappily a soldier may not always choose his weapons, and when life is at stake he seizes the first he finds within his reach. The papacy has not always been reactionary and obscurantist; when it overthrew the Cathari, for example, its victory was that of reason and good sense. The list of the heresies of the thirteenth century is already long, but it is increasing every day, to the great joy of those erudite ones who are making strenuous efforts to classify everything in that tohu-bohu of mysticism and folly. In that day heresy was very much alive; it was consequently very complex and its powers of transformation infinite. One may indicate its currents, mark its direction, but to go farther is to condemn oneself to utter confusion in this medley of impulsive, passionate, fantastic movements which were born, shot upward, and fell to earth again, at the caprice of a thousand incomprehensible circumstances. In certain counties of England there are at the present day villages having as many as eight and ten places of worship for a few hundreds of inhabitants. Many of these people change their denomination every three or four years, returning to that they first quitted, leaving it again only to enter it anew, and so on as long as they live. Their leaders set the example, throwing themselves enthusiastically into each new movement only to leave it before long. They would all alike find it difficult to give an intelligible reason for these changes. They say that the Spirit guides them, and it would be unfair to disbelieve them, but the historian who should investigate conditions like these would lose his head in the labyrinth unless he made a separate study of each of these Protean movements. They are surely not worth the trouble.
