This passage comes from a chapter entitled “Of the Origin of Ambition and of the Distinction of Ranks” in Adam Smith, The Theory of Moral Sentiments (1759):
Are you in earnest resolved never to barter your liberty for the lordly servitude of a court, but to live free, fearless, and independent? (Then…) (n)ever enter the place from whence so few have been able to return; never come within the circle of ambition; nor ever bring yourself into comparison with those masters of the earth who have already engrossed the attention of half mankind before you.
‘Love,’ says my Lord Rochfaucault, ‘is commonly succeeded by ambition; but ambition is hardly ever succeeded by love.’ That passion, when once it has got entire possession of the breast, will admit neither a rival nor a successor. To those who have been accustomed to the possession, or even to the hope of public admiration, all other pleasures sicken and decay. Of all the discarded statesmen who for their own ease have studied to get the better of ambition, and to despise those honours which they could no longer arrive at, how few have been able to succeed? The greater part have spent their time in the most listless and insipid indolence, chagrined at the thoughts of their own insignificancy, incapable of being interested in the occupations of private life, without enjoyment, except when they talked of their former greatness, and without satisfaction, except when they were employed in some vain project to recover it. Are you in earnest resolved never to barter your liberty for the lordly servitude of a court, but to live free, fearless, and independent? There seems to be one way to continue in that virtuous resolution; and perhaps but one. Never enter the place from whence so few have been able to return; never come within the circle of ambition; nor ever bring yourself into comparison with those masters of the earth who have already engrossed the attention of half mankind before you.
Of such mighty importance does it appear to be, in the imaginations of men, to stand in that situation which sets them most in the view of general sympathy and attention. And thus, place, that great object which divides the wives of aldermen, is the end of half the labours of human life; and is the cause of all the tumult and bustle, all the rapine and injustice, which avarice and ambition have introduced into this world. People of sense, it is said, indeed despise place; that is, they despise sitting at the head of the table, and are indifferent who it is that is pointed out to the company by that frivolous circumstance, which the smallest advantage is capable of overbalancing. But rank, distinction pre–eminence, no man despises, unless he is either raised very much above, or sunk very much below, the ordinary standard of human nature; unless he is either so confirmed in wisdom and real philosophy, as to be satisfied that, while the propriety of his conduct renders him the just object of approbation, it is of little consequence though he be neither attended to, nor approved of; or so habituated to the idea of his own meanness, so sunk in slothful and sottish indifference, as entirely to have forgot the desire, and almost the very wish, for superiority.
