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 and be the foundation of the laws of all nations. But tho’ the reasonings of lawyers did produce something of this kind, and though no man has treated systematically of the laws of any particular country, without intermixing in his work many observations of this sort; it was very late in the world before any such general system was thought of, or before the philosophy of law was treated of by itself, and without regard to the particular institutions of any one nation. In none of the ancient moralists, do we find any attempt towards a particular enumeration of the rules of justice. Cicero in his Offices, and Aristotle in his Ethics, treat of justice in the same general manner in which they treat of all the other virtues. In the laws of Cicero and Plato, where we might naturally have expected some attempts towards an enumeration of those rules of natural equity, which ought to be enforced by the positive laws of every country, there is however, nothing of this kind. Their laws are laws of police, not of justice. Grotius seems to have been the first, who attempted to give the world any thing like a system of those principles which ought to run through, and be the foundation of the laws of all nations; and his treatise of the laws of war and peace, with all its imperfections, is perhaps at this day the most complete work that has yet been given upon this subject. I shall in another discourse endeavour to give an account of the general principles of law and government, and of the different revolutions they have undergone in the different ages and periods of society, not only in what concerns justice, but in what concerns police, revenue, and arms, and whatever else is the object of law. I shall not, therefore, at present enter into any further detail concerning the history of jurisprudence. THE END.
