The Theory of Moral Sentiments

and cannot yet be considered as making part of the English tongue. The word approbation has but within these few years been appropriated to denote peculiarly anything of this kind. In propriety of language we approve of whatever is entirely to our satisfaction, of the form of a building, of the contrivance of a machine, of the flavour of a dish of meat. The word conscience does not immediately denote any moral faculty by which we approve or disapprove. Conscience supposes, indeed, the existence of some such faculty, and properly signifies our consciousness of having acted agreeably or contrary to its directions. When love, hatred, joy, sorrow, gratitude, resentment, with so many other passions which are all supposed to be the subjects of this principle, have made themselves considerable enough to get titles to know them by, is it not surprising that the sovereign of them all should hitherto have been so little heeded, that, a few philosophers excepted, nobody has yet thought it worth while to bestow a name upon that principle.

When we approve of any character or action, the sentiments which we feel, are, according to the foregoing system, derived from four sources, which are in some respects different from one another. First, we sympathize with the motives of the agent; secondly, we enter into the gratitude of those who receive the benefit of his actions; thirdly, we observe that his conduct has been agreeable to the general rules by which those two sympathies generally act; and, last of all, when we consider such actions as making a part of a system of behaviour which tends to promote the happiness either of the individual or of the society, they appear to derive a beauty from this utility, not unlike that which we ascribe to any well-contrived machine. After deducting, in any one particular case, all that must be acknowledged to proceed from some one or other of these four principles, I should be glad to know what remains, and I shall freely allow this overplus to be ascribed to a moral sense, or to any other peculiar faculty, provided anybody will ascertain precisely what this overplus is. It might be expected, perhaps, that if there was any such peculiar principle, such as this moral sense is supposed to be, we should feel it, in some particular cases, separated and detached from every other, as we often feel joy, sorrow, hope, and fear, pure and unmixed with any other emotion. This, however, I imagine, cannot even be pretended. I have never heard any instance alleged in which this principle could be said to exert itself alone and unmixed with sympathy or antipathy, with gratitude or resentment, with the perception of the agreement or disagreement of any action to an established rule, or last of all, with that general taste for beauty and order which is excited by inanimated as well as by animated objects.

II. There is another system which attempts to account for the origin of our moral sentiments from sympathy, distinct from that which I have been endeavouring to establish. It is that which places virtue in utility, and accounts for the pleasure with which the spectator surveys the utility of any quality from sympathy with the happiness of those who are affected by it. This sympathy is different both from that by which we enter into the motives of the agent, and from that by which we go along with the gratitude of the persons who are benefited by his actions. It is the same principle with that by which we approve of a well-contrived machine. But no machine can be the object of either of those two last-mentioned sympathies. I have already, in the fourth part of this discourse, given some account of this system.

Section IV

Of the Manner in Which Different Authors Have Treated of the Practical Rules of Morality

It was observed in the third part of this discourse, that the rules of justice are the only rules of morality which are precise and accurate; that those of all the other virtues are loose, vague, and indeterminate; that the first may be compared to the rules of grammar; the others to those which critics lay down for the attainment of what is sublime and elegant in composition, and which present us rather with a general idea of the perfection we ought to aim at, than afford us any certain and infallible directions for acquiring it.

As the different rules of morality admit such different degrees of accuracy, those authors who have endeavoured to collect and digest them into systems have done it in two different manners; and one set has followed through the whole that loose method to which they were naturally directed by the consideration of one species of virtues; while another has as universally endeavoured to introduce into their precepts that sort of accuracy of which only some of them are susceptible. The first have written like critics, the second like grammarians.

I. The first, among whom we may count all the ancient moralists, have contented themselves with describing in a general manner the different vices and virtues, and with pointing out the deformity and misery of the one disposition, as well as the propriety and happiness of the other, but have not affected to lay down many precise rules that are to hold good unexceptionally in all particular cases. They have only endeavoured to ascertain, as far as language is capable of ascertaining, first, wherein consists the sentiment of the heart, upon which each particular virtue is founded, what sort of internal feeling or emotion it is which constitutes the essence of friendship, of humanity, of generosity, of justice, of magnanimity, and of all the other virtues, as well as of the vices which are opposed to them: and, secondly, what is the general way of acting, the ordinary tone and tenor of conduct to which each of those sentiments would direct us, or how it is that
