CONCERNING MORAL SENTIMENT
IF the foregoing hypothesis be received, it will now be easy for us to determine the question first started, [FOOTNOTE: Sect. 1.] concerning the general principles of morals; and though we postponed the decision of that question, lest it should then involve us in intricate speculations, which are unfit for moral discourses, we may resume it at present, and examine how far either REASON or SENTIMENT enters into all decisions of praise or censure.
One principal foundation of moral praise being supposed to lie in the usefulness of any quality or action, it is evident that REASON must enter for a considerable share in all decisions of this kind; since nothing but that faculty can instruct us in the tendency of qualities and actions, and point out their beneficial consequences to society and to their possessor. In many cases this is an affair liable to great controversy: doubts may arise; opposite interests may occur; and a preference must be given to one side, from very nice views, and a small overbalance of utility. This is particularly remarkable in questions with regard to justice; as is, indeed, natural to suppose, from that species of utility which attends this virtue [Footnote: See App. II.]. Were every single instance of justice, like that of benevolence, useful to society; this would be a more simple state of the case, and seldom liable to great controversy. But as single instances of justice are often pernicious in their first and immediate tendency, and as the advantage to society results only from the observance of the general rule, and from the concurrence and combination of several persons in the same equitable conduct; the case here becomes more intricate and involved. The various circumstances of society; the various consequences of any practice; the various interests which may be proposed; these, on many occasions, are doubtful, and subject to great discussion and inquiry. The object of municipal laws is to fix all the questions with regard to justice: the debates of civilians; the reflections of politicians; the precedents of history and public records, are all directed to the same purpose. And a very accurate REASON or JUDGEMENT is often requisite, to give the true determination, amidst such intricate doubts arising from obscure or opposite utilities.
But though reason, when fully assisted and improved, be sufficient to instruct us in the pernicious or useful tendency of qualities and actions; it is not alone sufficient to produce any moral blame or approbation. Utility is only a tendency to a certain end; and were the end totally indifferent to us, we should feel the same indifference towards the means. It is requisite a SENTIMENT should here display itself, in order to give a preference to the useful above the pernicious tendencies. This SENTIMENT can be no other than a feeling for the happiness of mankind, and a resentment of their misery; since these are the different ends which virtue and vice have a tendency to promote. Here therefore REASON instructs us in the several tendencies of actions, and HUMANITY makes a distinction in favour of those which are useful and beneficial.
This partition between the faculties of understanding and sentiment, in all moral decisions, seems clear from the preceding hypothesis. But I shall suppose that hypothesis false: it will then be requisite to look out for some other theory that may be satisfactory; and I dare venture to affirm that none such will ever be found, so long as we suppose reason to be the sole source of morals. To prove this, it will be proper t o weigh the five following considerations.
I. It is easy for a false hypothesis to maintain some appearance of truth, while it keeps wholly in generals, makes use of undefined terms, and employs comparisons, instead of instances. This is particularly remarkable in that philosophy, which ascribes the discernment of all moral distinctions to reason alone, without the concurrence of sentiment. It is impossible that, in any particular instance, this hypothesis can so much as be rendered intelligible, whatever specious figure it may make in general declamations and discourses. Examine the crime of INGRATITUDE, for instance; which has place, wherever we observe good-will, expressed and known, together with good-offices performed, on the one side, and a return of ill-will or indifference, with ill-offices or neglect on the other: anatomize all these circumstances, and examine, by your reason alone, in what consists the demerit or blame. You never will come to any issue or conclusion.
Reason judges either of MATTER OF FACT or of RELATIONS. Enquire then, first, where is that matter of fact which we here call crime; point it out; determine the time of its existence; describe its essence or nature; explain the sense or faculty to which it discovers itself. It resides in the mind of the person who is ungrateful. He must, therefore, feel it, and be conscious of it. But nothing is there, except the passion of ill-will or absolute indifference. You cannot say that these, of themselves, always, and in all circumstances, are crimes. No, they are only crimes when directed towards persons who have before expressed and displayed good-will towards us. Consequently, we may infer, that the crime of ingratitude is not any particular individual FACT; but arises from a complication of circumstances, which, being presented to the spectator, excites the SENTIMENT of blame, by the particular structure and fabric of his mind.
This representation, you say, is false. Crime, indeed, consists not in a particular FACT, of whose reality we are assured by reason; but it consists in certain MORAL RELATIONS, discovered by reason, in the same manner as we discover by reason the truths of geometry or algebra. But what are the relations, I ask, of which you here talk? In the case stated above, I see first good-will and good-offices in one person; then ill-will and ill-offices in the other. Between these, there is a relation of CONTARIETY. Does the crime consist in that relation? But suppose a person bore me ill-will or did me ill-offices; and I, in return, were indifferent towards him, or did him good offices. Here is the same relation of CONTRARIETY; and yet my conduct is often highly laudable. Twist and turn this matter as much as you will, you can never rest the morality on relation; but must have recourse to the decisions of sentiment.
When it is affirmed that two and three are equal to the half of ten, this relation of equality I understand perfectly. I conceive, that if ten be divided into two parts, of which one has as many units as the other; and if any of these parts be compared to two added to three, it will contain as many units as that compound number. But when you draw thence a comparison to moral relations, I own that I am altogether at a loss to understand you. A moral action, a crime, such as ingratitude, is a complicated object. Does the morality consist in the relation of its parts to each other? How? After what manner? Specify the relation: be more particular and explicit in your propositions, and you will easily see their falsehood.
No, say you, the morality consists in the relation of actions to the rule of right; and they are denominated good or ill, according as they agree or disagree with it. What then is this rule of right? In what does it consist? How is it determined? By reason, you say, which examines the moral relations of actions. So that moral relations are determined by the comparison of action to a rule. And that rule is determined by considering the moral relations of objects. Is not this fine reasoning?
All this is metaphysics, you cry. That is enough; there needs nothing more to give a strong presumption of falsehood. Yes, reply I, here are metaphysics surely; but they are all on your side, who advance an abstruse hypothesis, which can never be made intelligible, nor quadrate with any particular instance or illustration. The hypothesis which we embrace is plain. It maintains that morality is determined by sentiment. It defines virtue to be WHATEVER MENTAL ACTION OR QUALITY GIVES TO A SPECTATOR THE PLEASING SENTIMENT OF APPROBATION; and vice the contrary. We then proceed to examine a plain matter of fact, to wit, what actions have this influence. We consider all the circumstances in which these actions agree, and thence endeavour to extract some general observations with regard to these sentiments. If you call this metaphysics, and find anything abstruse here, you need only conclude that your turn of mind is not suited to the moral sciences.
II. When a man, at any time, deliberates concerning his own conduct (as, whether he had better, in a particular emergence, assist a brother or a benefactor), he must consider these separate relations, with all the circumstances and situations of the persons, in order to determine the superior duty and obligation; and in order to determine the proportion of lines in any triangle, it is necessary to examine the nature of that figure, and the relation which its several parts bear to each other. But notwithstanding this appearing similarity in the two cases, there is, at bottom, an extreme difference between them. A speculative reasoner concerning triangles or circles considers the several known and given relations of the parts of these figures; and thence infers some unknown relation, which is dependent on the former. But in moral deliberations we must be acquainted beforehand with all the objects, and all their relations to each other; and from a comparison of the whole, fix our choice or approbation. No new fact to be ascertained; no new relation to be discovered. All the circumstances of the case are supposed to be laid before us, ere we can fix any sentence of blame or approbation. If any material circumstance be yet unknown or doubtful, we must first employ our inquiry or intellectual faculties to assure us of it; and must suspend for a time all moral decision or sentiment. While we are ignorant whether a man were aggressor or not, how can we determine whether the person who killed him be criminal or innocent? But after every circumstance, every relation is known, the understanding has no further room to operate, nor any object on which it could employ itself. The approbation or blame which then ensues, cannot be the work of the judgement, but of the heart; and is not a speculative proposition or affirmation, but an active feeling or sentiment. In the disquisitions of the understanding, from known circumstances and relations, we infer some new and unknown. In moral decisions, all the circumstances and relations must be previously known; and the mind, from the contemplation of the whole, feels some new impression of affection or disgust, esteem or contempt, approbation or blame.
