From the Theory of Moral Sentiments:
Smith: Theory of Moral Sentiments: When we consider the condition of the great, in those delusive colours in which the imagination is apt to paint it. it seems to be almost the abstract idea of a perfect and happy state. It is the very state which, in all our waking dreams and idle reveries, we had sketched out to ourselves as the final object of all our desires. We feel, therefore, a peculiar sympathy with the satisfaction of those who are in it. We favour all their inclinations, and forward all their wishes. What pity, we think, that any thing should spoil and corrupt so agreeable a situation! We could even wish them immortal; and it seems hard to us, that death should at last put an end to such perfect enjoyment. It is cruel, we think, in Nature to compel them from their exalted stations to that humble, but hospitable home, which she has provided for all her children.
"Great King, live for ever!" is the compliment, which, after the manner of eastern adulation, we should readily make them, if experience did not teach us its absurdity. Every calamity that befals them, every injury that is done them, excites in the breast of the spectator ten times more compassion and resentment than he would have felt, had the same things happened to other men…. To disturb, or to put an end to such perfect enjoyment, seems to be the most atrocious of all injuries. The traitor who conspires against the life of his monarch, is thought a greater monster than any other murderer. All the innocent blood that was shed in the civil wars, provoked less indignation than the death of Charles I.
A stranger to human nature, who saw the indifference of men about the misery of their inferiors, and the regret and indignation which they feel for the misfortunes and sufferings of those above them, would be apt to imagine, that pain must be more agonizing, and the convulsions of death more terrible to persons of higher rank, than to those of meaner stations.
Upon this disposition of mankind, to go along with all the passions of the rich and the powerful, is founded the distinction of ranks, and the order of society. Our obsequiousness to our superiors more frequently arises from our admiration for the advantages of their situation, than from any private expectations of benefit from their good-will…. Neither is our deference to their inclinations founded chiefly, or altogether, upon a regard to the utility of such submission, and to the order of society, which is best supported by it. Even when the order of society seems to require that we should oppose them, we can hardly bring ourselves to do it.
That kings are the servants of the people, to be obeyed, resisted, deposed, or punished, as the public conveniency may require, is the doctrine of reason and philosophy; but it is not the doctrine of Nature. Nature would teach us to submit to them for their own sake, to tremble and bow down before their exalted station, to regard their smile as a reward sufficient to compensate any services, and to dread their displeasure, though no other evil were to follow from it, as the severest of all mortifications. To treat them in any respect as men, to reason and dispute with them upon ordinary occasions, requires such resolution, that there are few men whose magnanimity can support them in it, unless they are likewise assisted by familiarity and acquaintance…
