as every individual, therefore, endeavors as much as can both to employ hid capital in the support of domestic industry, and so to direct that industry that its produce may be of the greatest value; every individual necessarily labors to render the annual revenue of the society as great as he can. He generally, indeed, neither intends to promote the public interest, nor know how much he is promoting it. By preferring the support of domestic to that foreign industry , he intends only his own security; and by directing the industry in such a manner as its produce may be of the greatest value, he intends only his own gain, and he is in this, as in many other case, led by an invisible hand to promote the an end which was on part of his intention. Nor is it always the worse for the society that is no part of it. By pursuing his own interest he frequently promote that of the society more effectually than when he really intends to promote it.
