It is remarkable that the moral decisions of the JESUITS and other relaxed casuists, were commonly formed in prosecution of some such subtilties of reasoning as are here pointed out, and proceed as much from the habit of scholastic refinement as from any corruption of the heart, if we may follow the authority of Mons. Bayle. See his Dictionary, article Loyola. And why has the indignation of mankind risen so high against these casuists; but because every one perceived, that human society could not subsist were such practices authorized, and that morals must always be handled with a view to public interest, more than philosophical regularity? If the secret direction of the intention, said every man of sense, could invalidate a contract; where is our security? And yet a metaphysical schoolman might think, that, where an intention was supposed to be requisite, if that intention really had not place, no consequence ought to follow, and no obligation be imposed. The casuistical subtilties may not be greater than the snbtilties of lawyers, hinted at above; but as the former are PERNICIOUS, and the latter INNOCENT and even NECESSARY, this is the reason of the very different reception they meet with from the world.
It is a doctrine of the Church of Rome, that the priest, by a secret direction of his intention, can invalidate any sacrament. This position is derived from a strict and regular prosecution of the obvious truth, that empty words alone, without any meaning or intention in the speaker, can never be attended with any effect. If the same conclusion be not admitted in reasonings concerning civil contracts, where the affair is allowed to be of so much less consequence than the eternal salvation of thousands, it proceeds entirely from men's sense of the danger and inconvenience of the doctrine in the former case: And we may thence observe, that however positive, arrogant, and dogmatical any superstition may appear, it never can convey any thorough persuasion of the reality of its objects, or put them, in any degree, on a balance with the common incidents of life, which we learn from daily observation and experimental reasoning.]
These reflections are far from weakening the obligations of justice, or diminishing anything from the most sacred attention to property. On the contrary, such sentiments must acquire new force from the present reasoning. For what stronger foundation can be desired or conceived for any duty, than to observe, that human society, or even human nature, could not subsist without the establishment of it; and will still arrive at greater degrees of happiness and perfection, the more inviolable the regard is, which is paid to that duty?
The dilemma seems obvious: As justice evidently tends to promote public utility and to support civil society, the sentiment of justice is either derived from our reflecting on that tendency, or like hunger, thirst, and other appetites, resentment, love of life, attachment to offspring, and other passions, arises from a simple original instinct in the human breast, which nature has implanted for like salutary purposes. If the latter be the case, it follows, that property, which is the object of justice, is also distinguished by a simple original instinct, and is not ascertained by any argument or reflection. But who is there that ever heard of such an instinct? Or is this a subject in which new discoveries can be made? We may as well expect to discover, in the body, new senses, which had before escaped the observation of all mankind.
But farther, though it seems a very simple proposition to say, that nature, by an instinctive sentiment, distinguishes property, yet in reality we shall find, that there are required for that purpose ten thousand different instincts, and these employed about objects of the greatest intricacy and nicest discernment. For when a definition of PROPERTY is required, that relation is found to resolve itself into any possession acquired by occupation, by industry, by prescription, by inheritance, by contract, &c. Can we think that nature, by an original instinct, instructs us in all these methods of acquisition?
These words too, inheritance and contract, stand for ideas infinitely complicated; and to define them exactly, a hundred volumes of laws, and a thousand volumes of commentators, have not been found sufficient. Does nature, whose instincts in men are all simple, embrace such complicated and artificial objects, and create a rational creature, without trusting anything to the operation of his reason?
But even though all this were admitted, it would not be satisfactory. Positive laws can certainly transfer property. It is by another original instinct, that we recognize the authority of kings and senates, and mark all the boundaries of their jurisdiction? Judges too, even though their sentence be erroneous and illegal, must be allowed, for the sake of peace and order, to have decisive authority, and ultimately to determine property. Have we original innate ideas of praetors and chancellors and juries? Who sees not, that all these institutions arise merely from the necessities of human society?
All birds of the same species in every age and country, built their nests alike: In this we see the force of instinct. Men, in different times and places, frame their houses differently: Here we perceive the influence of reason and custom. A like inference may be drawn from comparing the instinct of generation and the institution of property.
How great soever the variety of municipal laws, it must be confessed, that their chief outlines pretty regularly concur; because the purposes, to which they tend, are everywhere exactly similar. In like manner, all houses have a roof and walls, windows and chimneys; though diversified in their shape, figure, and materials. The purposes of the latter, directed to the conveniencies of human life, discover not more plainly their origin from reason and reflection, than do those of the former, which point all to a like end.
I need not mention the variations, which all the rules of property receive from the finer turns and connexions of the imagination, and from the subtilties and abstractions of law- topics and reasonings. There is no possibility of reconciling this observation to the notion of original instincts.
What alone will beget a doubt concerning the theory, on which I insist, is the influence of education and acquired habits, by which we are so accustomed to blame injustice, that we are not, in every instance, conscious of any immediate reflection on the pernicious consequences of it. The views the most familiar to us are apt, for that very reason, to escape us; and what we have very frequently performed from certain motives, we are apt likewise to continue mechanically, without recalling, on every occasion, the reflections, which first determined us. The convenience, or rather necessity, which leads to justice is so universal, and everywhere points so much to the same rules, that the habit takes place in all societies; and it is not without some scrutiny, that we are able to ascertain its true origin. The matter, however, is not so obscure, but that even in common life we have every moment recourse to the principle of public utility, and ask, WHAT MUST BECOME OF THE WORLD, IF SUCH PRACTICES PREVAIL? HOW COULD SOCIETY SUBSIST UNDER SUCH DISORDERS? Were the distinction or separation of possessions entirely useless, can any one conceive, that it ever should have obtained in society?
Thus we seem, upon the whole, to have attained a knowledge of the force of that principle here insisted on, and can determine what degree of esteem or moral approbation may result from reflections on public interest and utility. The necessity of justice to the support of society is the sole foundation of that virtue; and since no moral excellence is more highly esteemed, we may conclude that this circumstance of usefulness has, in general, the strongest energy, and most entire command over our sentiments. It must, therefore, be the source of a considerable part of the merit ascribed to humanity, benevolence, friendship, public spirit, and other social virtues of that stamp; as it is the sole source of the moral approbation paid to fidelity, justice, veracity, integrity, and those other estimable and useful qualities and principles. It is entirely agreeable to the rules of philosophy, and even of common reason; where any principle has been found to have a great force and energy in one instance, to ascribe to it a like energy in all similar instances. This indeed is Newton's chief rule of philosophizing [Footnote: Principia. Lib. iii.].
