I have no great faith in political arithmetic, and I mean not to warrant the exactness of either of these computations.

The interest of the dealers, however, in any particular branch of trade or manufactures, is always in some respects different from, and even opposite to, that of the public. To widen the market and to narrow the competition, is always the interest of the dealers.

Thus the labour of a manufacture adds, generally, to the value of the materials which he works upon, that of his own maintenance, and of his masters profits. The labour of a menial servant, on the contrary, adds to the value of nothing.

To hinder, besides, the farmer from selling his goods at all times to the best market, is evidently to sacrifice the ordinary laws of justice to an idea of public utility, to a sort of reasons of state; an act of legislative authority which ought to be exercised only, which can be pardoned only in cases of the most urgent necessity.

Men of the most robust make, observe that in looking upon sore eyes they often feel a very sensible soreness in their own, which proceeds from the same reason; that organ being in the strongest man more delicate, than any other part of the body is in the weakest.

That this is the source of our fellow-feeling for the misery of others, that it is by changing places in fancy with the sufferer, that we come either to conceive or to be affected by what he feels, may be demonstrated by many obvious observations, if it should not be thought sufficiently evident of itself. When we see a stroke aimed and just ready to fall upon the leg or arm of another person, we naturally shrink and draw back our own leg or our own arm; and when it does fall, we feel it in some measure, and are hurt by it as well as the sufferer.
