To Seek Power is to Lose Liberty
Men in great place are thrice servants: servants of the sovereign or state; servants of fame; and servants of business. So as they have no freedom; neither in their persons, nor in their actions, nor in their times. It is a strange desire, to seek power and to lose liberty: or to seek power over others, and to lose power over a man's self. The rising unto place is laborious; and by pains, men come to greater pains; and it is sometimes base; and by indignities, men come to dignities. The standing is slippery, and the regress is either a downfall, or at least an eclipse, which is a melancholy thing. Cum non sis qui fueris, non esse cur velis vivere. Nay, retire men cannot when they would, neither will they, when it were reason; but are impatient of privateness, even in age and sickness, which require the shadow; like old towns men, that will be still sitting at their street door, though thereby they offer age to scom. Certainly great persons had need to borrow other men's opinions, to think themselves happy; for if they judge by their own feeling, they cannot find it; but if they think with themselves, what other men think of them, and that other men would fain be, as they are, then they are happy, as it were, by report; when perhaps they find the contrary within. For they are the first, that find their own griefs, though they be the last, that find their own faults.
