Every individual necessarily labors to render the annual revenue of society as great as he can. He generally neither intends to promote the public interest, nor knows how much he is promoting it. He intends only his own gain, and he is, in this, as in many other cases, led by an invisible hand to promote an end which was not part of his intention.
The necessaries of life occasion the great expense of the poor. They find it difficult to get food, and the greater part of their little revenue is spent in getting it. The luxuries and vanities of life occasion the principal expense of the rich, and a magnificent house embellishes and sets off to the best advantage all the other luxuries and vanities which they possess ... It is not very unreasonable that the rich should contribute to the public expense, not only in proportion to their revenue, but something more than in that proportion.
Whenever the legislature attempts to regulate differences between masters and their workmen, its counsellors are always the masters. When the regulation, therefore, is in favor of the workmen, it is always just and equitable; but it is sometimes otherwise when in favor of the masters.
It may indeed be doubted whether butchers' meet is anywhere a necessary of life. Grain and other vegetables, with the help of milk, cheese, and butter, or oil where butter is not to be had, afford the most plentiful, the most wholesome, the most nourishing, and the most invigorating diet. Decency nowhere requires that any man should eat butchers' meat.

Adventure upon all the tickets in the lottery, and you lose for certain; and the greater the number of your tickets the nearer your approach to this certainty.
Though the profusion of Government must undoubtedly have retarded the natural progress of England to wealth and improvement, it has not been able to stop it.
By pursuing his own interest (the individual) frequently promotes that of the society more effectually than when he really intends to promote it. I have never known much good done by those who affected to trade for the public good.
It is the interest of every man to live as much at his ease as he can; and if his emoluments are to be precisely the same, whether he does or does not perform some very laborious duty, it is certainly his interest, at least as interest is vulgarly understood, either to neglect it altogether, or, if he is subject to some authority which will not suffer him to do this, to perform it in as careless and slovenly a manner as that authority will permit.
For a very small expence the public can facilitate, can encourage, and can even impose upon almost the whole body of the people, the necessity of acquiring those most essential parts of education.
