The sneaking arts of underling tradesmen are thus erected into political maxims for the conduct of a great empire; for it is the most underling trade… - Adam Smith

The evident justice and utility of the foregoing maxims have recommended them more or less to the attention of all nations.

The man of system, on the contrary, is apt to be very wise in his own conceit; and is often so enamoured with the supposed beauty of his own ideal plan of government, that he cannot suffer the smallest deviation from any part of it. He goes on to establish it completely and in all its parts, without any regard either to the great interests, or to the strong prejudices which may oppose it. He seems to imagine that he can arrange the different members of a great society with as much ease as the hand arranges the different pieces upon a chess-board. He does not consider that the pieces upon the chess-board have no other principle of motion besides that which the hand impresses upon them; but that, in the great chess-board of human society, every single piece has a principle of motion of its own, altogether different from that which the legislature might choose to impress upon it. If those two principles coincide and act in the same direction, the game of human society will go on easily and harmoniously, and is very likely to be happy and successful. If they are opposite or different, the game will go on miserably, and the society must be at all times in the highest degree of disorder.

We do not, however, reckon that trade disadvantageous which consists in the exchange of the hard-ware of England for the wines of France;and yet hard-ware is a very durable commodity, and were it not for this continual exportation, might too be accumulated for ages together, to the incredible augmentation of the pots and pans of the country. But it readily occurs that the number of such utensils is in every country necessarily limited by the use which there is for them;that it would be absurd to have more pots and pans than were necessary for cooking the victuals usually consumed there;and that if the quantity of victuals were to increase, the number of pots and pans would readily increase along with it, apart of the increased quantity of victuals being employed in purchasing them, or in maintaining an additional number of workman whose business it was to make them.
