THREE: Infamy is a sign of public disapprobation, depriving a criminal of the good-will of his countrymen, of their confidence, and of that feeling almost of fraternity that a common life inspires. It does not depend upon the laws. Hence the infamy which the laws inflict should be the same as that which arises from the natural relations of things, the same as that taught by universal morality, or by that particular morality, which depends on particular systems, and sets the law for ordinary opinions or for this and that nation. If the one kind of infamy is different from the other, either the law loses in public esteem, or the ideas of morality and honesty disappear, in spite of declamations, which are never efficacious against facts. Whoever declares actions to be infamous which are in themselves indifferent, detracts from the infamy of actions that are really in themselves infamous.Divine justice and natural justice are in their essence immutable and constant, because the relation between similar things is always the same; but human or political justice, being nothing more than a relation between a given action and a given state of society, may vary according as such action becomes necessary or useful to society; nor is such justice easily discernible, save by one who analyses the complex and very changeable relations of civil combinations. When once these principles, essentially distinct, become confused, there is no more hope of sound reasoning about public matters. It appertains to the theologian to fix the boundaries between the just and the unjust, in so far as regards the intrinsic goodness or wickedness of an act; to fix the relations between the politically just and unjust appertains to the publicist; nor can the one object cause any detriment to the other, when it is obvious how the virtue that is purely political ought to give place to that immutable virtue which emanates from God.
