The Pequod Review:
The Theory of Moral Sentiments is Adam Smith’s best book, and one of the great works of political philosophy and morality. The book is part social psychology (describing the formation of human consciousness and empathy), part moral philosophy (reviewing what it means to be virtuous, and how it is that we can be both selfish and generous), and part sermon (explaining how we should live our life) — all with deep insights across a wide range of human behavior.
Here for example Smith imagines a hypothetical tragedy in order to show the limits (and inconsistencies) of human sympathies:
Let us suppose that the great empire of China, with all its myriads of inhabitants, was suddenly swallowed up by an earthquake, and let us consider how a man of humanity in Europe, who had no sort of connection with that part of the world, would be affected upon receiving intelligence of this dreadful calamity.
He would, I imagine, first of all, express very strongly his sorrow for the misfortune of that unhappy people, he would make many melancholy reflections upon the precariousness of human life, and the vanity of all the labors of man, which could thus be annihilated in a moment. He would too, perhaps, if he was a man of speculation, enter into many reasonings concerning the effects which this disaster might produce upon the commerce of Europe, and the trade and business of the world in general. And when all this fine philosophy was over, when all these humane sentiments had been once fairly expressed, he would pursue his business or his pleasure, take his repose or his diversion, with the same ease and tranquility, as if no such accident had happened.
The most frivolous disaster which could befall himself would occasion a more real disturbance. If he was to lose his little finger to-morrow, he would not sleep to-night; but, provided he never saw them, he will snore with the most profound security over the ruin of a hundred millions of his brethren, and the destruction of that immense multitude seems plainly an object less interesting to him, than this paltry misfortune of his own.
Despite this natural tendency, Smith recognizes the fact that no reasonable person would (if given the choice) allow millions to die in order to save his own finger:
To prevent, therefore, this paltry misfortune to himself, would a man of humanity be willing to sacrifice the lives of a hundred millions of his brethren, provided he had never seen them? Human nature startles with horror at the thought, and the world, in its greatest depravity and corruption, never produced such a villain as could be capable of entertaining it. But what makes this difference? When our passive feelings are almost always so sordid and so selfish, how comes it that our active principles should often be so generous and so noble? When we are always so much more deeply affected by whatever concerns ourselves, than by whatever concerns other men; what is it which prompts the generous, upon all occasions, and the mean upon many, to sacrifice their own interests to the greater interests of others?
So what accounts for our reluctance to behave in a selfish fashion? In an entirely unique insight, Smith goes beyond the typical explanations that attribute it to our "conscience" or to God, and shows how we often imagine the presence of an impartial third-party observer (someone we are looking to impress or at least not be ashamed in front of) who is viewing our actions:
It is not the soft power of humanity, it is not that feeble spark of benevolence which Nature has lighted up in the human heart, that is thus capable of counteracting the strongest impulses of self-love. It is a stronger power, a more forcible motive, which exerts itself upon such occasions. It is reason, principle, conscience, the inhabitant of the breast, the man within, the great judge and arbiter of our conduct.
It is he who, whenever we are about to act so as to affect the happiness of others, calls to us, with a voice capable of astonishing the most presumptuous of our passions, that we are but one of the multitude, in no respect better than any other in it; and that when we prefer ourselves so shamefully and so blindly to others, we become the proper objects of resentment, abhorrence, and execration. It is from him only that we learn the real littleness of ourselves, and of whatever relates to ourselves, and the natural misrepresentations of self–love can be corrected only by the eye of this impartial spectator. It is he who shows us the propriety of generosity and the deformity of injustice; the propriety of resigning the greatest interests of our own, for the yet greater interests of others, and the deformity of doing the smallest injury to another, in order to obtain the greatest benefit to ourselves. It is not the love of our neighbor, it is not the love of mankind, which upon many occasions prompts us to the practice of those divine virtues. It is a stronger love, a more powerful affection, which generally takes place upon such occasions; the love of what is honorable and noble, of the grandeur, and dignity, and superiority of our own characters.
Throughout the book, Smith brings so many such observations to human behavior. Here he explores the grey areas of dishonesty that we all operate in:
The prudent man is always sincere, and feels horror at the very thought of exposing himself to the disgrace which attends upon the detection of falsehood. But though always sincere, he is not always frank and open; and though he never tells any thing but the truth, he does not always think himself bound, when not properly called upon, to tell the whole truth. As he is cautious in his actions, so he is reserved in his speech; and never rashly or unnecessarily obtrudes his opinion concerning either things or persons.
And he understands just as well as the Buddhist philosophers that money doesn't lead to happiness:
The great source of both the misery and disorders of human life, seems to arise from over-rating the difference between one permanent situation and another. Avarice over-rates the difference between poverty and riches: ambition, that between a private and a public station: vain-glory, that between obscurity and extensive reputation. The person under the influence of any of those extravagant passions, is not only miserable in his actual situation, but is often disposed to disturb the peace of society, in order to arrive at that which he so foolishly admires. The slightest observation, however, might satisfy him, that, in all the ordinary situations of human life, a well-disposed mind may be equally calm, equally cheerful, and equally contented. Some of those situations may, no doubt, deserve to be preferred to others: but none of them can deserve to be pursued with that passionate ardor which drives us to violate the rules either of prudence or of justice; or to corrupt the future tranquility of our minds, either by shame from the remembrance of our own folly, or by remorse from the horror of our own injustice.
These are rich and timeless concerns, and this is a rich and timeless book. From start to finish, Adam Smith has an endless curiosity about human behavior and human psychology, and his observations are consistently enlightening. Highly recommended.
