Prologue

In the first volume of this work, which is inscribed: "On Principles," there are found declared the wholly general principles of the whole of moral theology, and besides those special principles which regard the theological virtues. But since these virtues are concerned with the ultimate end itself, and in operable things the end is the first principle, hence those things which regard the theological virtues are also held among the more general principles of those things which rule practical science.

Now we come to treat of those things which are concerned with the means to the ultimate end. Some means are intrinsically necessary from the very nature of the thing, and to these the moral virtues dispose us, which are the four cardinal virtues with their annexed virtues; others are due from the positive and extrinsic ordination of God, namely, the sacraments instituted by Christ.

Leaving sacramental doctrine for the third volume, in this second volume is contained the ample matter concerning the cardinal and annexed virtues, with their acts, and the precepts and gifts pertaining to them, the opposite sins being at the same time considered; and indeed according to the doctrine and ordering of St. Thomas.

But since there are several positive determinations concerning these things, such as of ecclesiastical law concerning religion or temperance, or of civil law especially in the matter of justice, present-day law also will have to be considered, both canonical and civil: especially French law, which, having been worked out earlier and having been adopted in our country for a great part, was an exemplar for very many modern legislations, whose dispositions nevertheless, at least in the principal matters, should not seem to be passed over, so that their analogies and differences and particular orderings may be brought to light.

Whatever good, friendly reader, you will find in the work, attribute to God, the fountain of all goods, and to the great doctors and masters whose doctrine is reported, especially St. Thomas; whatever there is of defect or imperfection, attribute to the author and his weakness.

May God will that not weakness prevail, but His Truth and Wisdom, unto His praise and glory and the salvation of souls.
