invariable, which at all times requires the same sacrifice of toil and labour to produce it. Of such a commodity we have no knowledge, but we may hypothetically argue and speak about it, as if we had; and may improve our knowledge of the science, by shewing distinctly the absolute inapplicability of all the standards which have been hitherto adopted. But supposing either of these to be a correct standard of value, still it would not be a standard of riches, for riches do not depend on value. A man is rich or poor, according to the abundance of necessaries and luxuries, which he can command; and whether the exchangeable value of these for money, for corn, or for labour, be high or low, they will equally contribute to the enjoyment of their possessor. It is through confounding the ideas of value and wealth, or riches, that it has been asserted, that by diminishing the quantity of commodities, that is to say, of the necessaries, conveniences, and enjoyments of human life, riches may be increased. If value were the measure of riches this could not be denied, because by scarcity the value of commodities is raised; but if Adam Smith be correct, if riches consist in necessaries and enjoyments, then they cannot be increased by a diminution of quantity.
It is true, that the man in possession of a scarce commodity is richer, if by means of it he can command more of the necessaries and enjoyments of human life; but as the general stock out of which each man's riches are drawn, is diminished in quantity, by all that any individual takes from it, other men's shares must necessarily be reduced in proportion as this favoured individual is able to appropriate a greater quantity to himself.
Let water become scarce, says Lord Lauderdale, and be exclusively possessed by an individual, and you will increase his riches, because water will then have value; and if wealth be the aggregate of individual riches, you will by the same means also increase wealth. You undoubtedly will increase the riches of this individual, but inasmuch as the farmer must sell a part of his corn, the shoemaker a part of his shoes, and all men give up a portion of their possessions for the sole purpose of supplying
