The Theory of Moral Sentiments - Adam Smith [229]
Something, indeed, not unlike the doctrine of the casuists, seems to have been attempted by several philosophers. There is something of this kind in the third book of Cicero’s Offices, where he endeavours like a casuist to give rules for our conduct in many nice cases, in which it is difficult to determine whereabouts the point of propriety may lie.14 It appears too, from many passages in the same book, that several other philosophers had attempted something of the same kind before him. Neither he nor they, however, appear to have aimed at giving a complete system of this sort, but only meant to show how situations may occur, in which it is doubtful, whether the highest propriety of conduct consists in observing or in receding from what, in ordinary cases, are the rules of duty.
Every system of positive law may be regarded as a more or less imperfect attempt towards a system of natural jurisprudence, or towards an enumeration of the particular rules of justice. As the violation of justice is what men will never submit to from one another, the public magistrate is under a necessity of employing the power of the commonwealth to enforce the practice of this virtue. Without this precaution, civil society would become a scene of bloodshed and disorder, every man revenging himself at his own hand whenever he fancied he was injured. To prevent the confusion which would attend upon every man’s doing justice to himself, the magistrate, in all governments that have acquired any considerable authority, undertakes to do justice to all, and promises to hear and to redress every complaint of injury. In all well-governed states too, not only judges are appointed for determining the controversies of individuals, but rules are prescribed for regulating the decisions of those judges; and these rules are, in general, intended to coincide with those of natural justice. It does not, indeed, always happen that they do so in every instance. Sometimes what is called the constitution of the state, that is, the interest of the government; sometimes the interest of particular orders of men who tyrannize the government, warp the positive laws of the country from what natural justice would prescribe. In some countries, the rudeness and barbarism of the people hinder the natural sentiments of justice from arriving at that accuracy and precision which, in more civilized nations, they naturally attain to. Their laws are, like their manners, gross and rude and undistinguishing. In other countries the unfortunate constitution of their courts of judicature hinders any regular system of jurisprudence from ever establishing itself among them, though the improved manners of the people may be such as would admit of the most accurate. In no country do the decisions of positive law coincide exactly, in every case, with the rules which the natural sense of justice would dictate. Systems of positive law, therefore, though they deserve the greatest authority, as the records of the sentiments of mankind in different ages and nations, yet can never be regarded as accurate systems of the rules of natural justice.
It might have been expected that the reasonings of lawyers, upon the different imperfections and improvements of the laws of different countries, should have given occasion to an inquiry into what were the natural rules of justice independent of all positive institution. It might have been expected that these reasonings should have led them to aim at establishing a system of what might properly be called natural jurisprudence, or a theory of the general principles which ought to run through
