If a great person has omitted rewarding your services, do not talk of it; perhaps he may not yet have had an opportunity, for they have always on hand expectants innumerable, and the clamorous are too generally gratified before the deserving; besides, it is the way to draw his displeasure upon you, which can do you no good, but make bad worse. If the services you did were voluntary, you ought not to expect any return, because you made a present of them unasked; and a free gift is not to be turned into a loan, to draw the person you have served into debt. If you have served a great person merely with a view to self-interest, perhaps he is aware of that, and rewards you accordingly: nor can you justly complain: he owes you nothing; it was not him you meant to serve.

That government only can be pronounced consistent with the design of all government, which allows to the governed the liberty of doing what, consistently with the general good, they may desire to do, and which only forbids their doing the contrary. Liberty does not exclude restraint; it only excludes unreasonable restraint. To determine precisely how far personal liberty is compatible with the general good, and of the propriety of social conduct in all cases, is a matter of great extent, and demands the united wisdom of a whole people. And the consent of the whole people, as far as it can be obtained, is indispensably necessary to every law, by which the whole people are to be bound; else the whole people are enslaved to the one, or the few, who frame the laws for them.

In mixed company, be readier to hear than to speak, and put people upon talking of what is in their own way; for then you will both oblige them, and be most likely to improve by their conversation.
