The Theory of Moral Sentiments

when he performs an operation upon his own person; and he is often equally bold who does not hesitate to pull off the mysterious veil of self-delusion, which covers from his view the deformities of his own conduct. Rather than see our own behaviour under so disagreeable an aspect, we too often, foolishly and weakly, endeavour to exasperate anew those unjust passions which had formerly misled us; we endeavour by artifice to awaken our old hatreds, and irritate afresh our almost forgotten resentments: we even exert ourselves for this miserable purpose, and thus persevere in injustice, merely because we once were unjust, and because we are ashamed and afraid to see that we were so.

So partial are the views of mankind with regard to the propriety of their own conduct, both at the time of action and after it; and so difficult is it for them to view it in the light in which any indifferent spectator would consider it. But if it was by a peculiar faculty, such as the moral sense is supposed to be, that they judged of their own conduct, if they were endued with a particular power of perception which distinguished the beauty or deformity of passions and affections; as then passions would be more immediately exposed to the view of this faculty, it would judge more accurately concerning them, than concerning those of other men, of which it had only a more distant prospect.

This self-deceit, this fatal weakness of mankind, is the source of half the disorders of human life. If we saw ourselves in the light in which others see us, or in which they would see us if they knew all, a reformation would generally be unavoidable. We could not otherwise endure the sight exposed to us.

Nature, however, has not left this weakness, which is of so much importance, altogether without a remedy; nor has she abandoned us entirely to the delusions of self-love. Our continual observations upon the conduct of others, insensibly lead us to form to ourselves certain general rules concerning what is fit and proper either to be done or to be avoided. Some of their actions shock all our natural sentiments. We hear everybody about us express the like detestation against them. This still further confirms, and even exasperates our natural sense of their deformity. It satisfies us that we view them in the proper light, when we see other people view them in the same light. We resolve never to be guilty of the like, nor ever, upon any account, to render ourselves in this manner the objects of universal disapprobation. We thus naturally lay down to ourselves a general rule, that all such actions are to be avoided, as tending to render us odious, contemptible, or punishable, the objects of all those sentiments for which we have the greatest dread and aversion. Other actions, on the contrary, call forth our approbation, and we hear everybody around us express the same favourable opinion concerning them. Everybody is eager to honour and reward them. They excite all those sentiments for which we have by nature the strongest desire; the love, the gratitude, the admiration of mankind. We become ambitious of performing the like; and thus naturally lay down to ourselves a rule of another kind, that every opportunity of acting in this manner is to be sought after.

It is thus that the general rules of morality are formed. They are ultimately founded upon experience of what, in particular instances, our moral faculties, our natural sense of merit and propriety, approve, or disapprove of. We do not originally approve or condemn particular actions; because, upon examination, they appear to be agreeable or inconsistent with a certain general rule. The general rule, on the contrary, is formed, by finding from experience, that all actions of a certain kind, or circumstanced in a certain manner, are approved or disapproved of. To the man who first saw an inhuman murder, committed from avarice, envy, or unjust resentment, and upon one too that loved and trusted the murderer, who beheld the last agonies of the dying person, who heard him, with his expiring breath, complain more of the perfidy and ingratitude of his false friend, than of the violence which had been done to him, there could be no occasion, in order to conceive how horrible such an action was, that he should reflect, that one of the most sacred rules of conduct was what prohibited the taking away the life of an innocent person, that this was a plain violation of that rule, and consequently a very blamable action. His detestation of this crime, it is evident, would arise instantaneously and antecedent to his having formed to himself any such general rule. The general rule, on the contrary, which he might afterwards form, would be founded upon the detestation which he felt necessarily arise in his own breast, at the thought of this and every other particular action of the same kind.

When we read in history or romance, the account of actions either of generosity or of baseness, the admiration which we conceive for the one, and the contempt which we feel for the other, neither of them arise from reflecting that there are certain general rules which declare all actions of the one kind admirable, and all actions of the other contemptible. Those general rules, on the contrary, are all formed from the experience we have had of the effects which actions of all different kinds naturally produce upon us.

An amiable action, a respectable action, an horrid action, are all of them actions which naturally excite for the person who performs them, the love, the respect, or the horror of the spectator. The general rules which determine what actions are, and what are not, the objects of each of those sentiments, can be formed no other way than by observing what actions actually and in fact excite them.

When these general rules, indeed, have been formed, when they are universally acknowledged and
