Corn is a necessary, silver is only a superfluity.

A power to dispose of estates for ever is manifestly absurd. The earth and the fulness of it belongs to every generation, and the preceding one can have no right to bind it up from posterity. Such extension of property is quite unnatural.

The great affair, we always find, is to get money.

In the long-run the workman may be as necessary to his master as his master is to him, but the necessity is not so immediate.

Among civilized and thriving nations, on the contrary, though a great number of people do no labor at all, many of whom consume the produce of ten times, frequently of a hundred times more labour than the greater part of those who work; yet the produce of the whole labour of the society is so great, that all are often abundantly supplied, and a workman, even of the lowest and poorest order, if he is frugal and industrious, may enjoy a greater share of the necessaries and conveniencies of life than it is possible for any savage to acquire.

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.

Have lots of experiments, but make sure they're strategically focused.
