translate English to French: We have on other occasions, and especially in Our encyclical letter Immortale Dei ,(2) in treating of the so-called modern liberties, distinguished between their good and evil elements; and We have shown that whatsoever is good in those liberties is as ancient as truth itself, and that the Church has always most willingly approved and practiced that good: but whatsoever has been added as new is, to tell the plain truth, of a vitiated kind, the fruit of the disorders of the age, and of an insatiate longing after novelties.
Ce que Nous avons directement en vue, c'est la liberté morale considérée soit dans les individus, soit dans la société. Il est bon cependant de dire tout d'abord quelques mots de la liberté naturelle, laquelle, bien que tout à fait distincte de la liberté morale, est pourtant la source et le principe d'où toute espèce de liberté découle d'elle-même et comme naturellement.
