2 And in this matter effort is the more needful because perils everywhere abound. The great virtues of our forefathers have in large measure disappeared; the most violent passions have claimed a freer indulgence; the madness of opinion which knows no restraint, or at least no effective restraint, every day extends further; of those whose principles are sound there are many who, through a misplaced timidity, are frightened, and have not the courage even to speak out their opinions boldly, far less to translate them into deeds; everywhere the worst examples are affecting public morals; wicked societies which We ourselves have denounced before now, skilled in all evil arts, are doing their best to lead the people astray, and as far as they are able, to withdraw them from God, their duty, and Christianity.
