Every craft may engross the whole of a man's attention, and has a mystery which must be studied or learned by a regular apprenticeship. Nations of tradesmen come to consist of members, who, beyond their own particular trade, are ignorant of all human affairs, and who may contribute to the preservation and enlargement of their commonwealth, without making its interest an object of their regard or attention. Every individual is distinguished by his calling, and has a place to which he is fitted. The savage, who knows no distinction but that of his merit, of his sex, or of his species, and to whom his community is the sovereign object of affection, is astonished to find, that in a scene of this nature, his being a man does not qualify him for any station whatever: he flies to the woods with amazement, distaste, and aversion. By the separation of arts and professions, the sources of wealth are laid open; every species of material is wrought up to the greatest perfection, and every commodity is produced in the greatest abundance. The state may estimate its profits and its revenues by the number of its people. It may procure, by its treasure, that national consideration and power, which the savage maintains at the expense of his blood. The advantage gained in the inferior branches of manufacture by the separation of their parts, seem to be equalled by those which arise from a similar device in the higher departments of policy and war. The soldier is relieved from every care but that of his service; statesmen divide the business of civil government into shares; and the servants of the public, in every office, without being skilful in the affairs of state, may succeed, by observing forms which are already established on the experience of others. They are made, like the parts of an engine, to concur to a purpose, without any concert of their own: and equally blind with the trader to any general combination, they unite with him, in furnishing to the state its resources, its conduct, and its force. The artifices of the beaver, the ant, and the bee, are ascribed to the wisdom of nature. Those of polished nations are ascribed to themselves, and are supposed to indicate a capacity superior to that of rude minds. But the establishments of men, like those of every animal, are suggested by nature, and are the result of instinct, directed by the variety of situations in which mankind are placed. Those establishments arose from successive improvements that were made, without any sense of their general effect; and they bring human affairs to a state of complication, which the greatest reach of capacity with which human nature was ever adorned, could not have projected; nor even when the whole is carried into execution, can it be comprehended in its full extent.
