If it be argued that in practice they do not press their principle to its most extreme consequences, I willingly grant it. This is always the case when one sets out with a false principle. Such a principle soon leads to results so absurd and so mischievous that we are obliged to stop short. This is the reason why practical industry never admits _sisyphism_; punishment would follow error too closely not to expose it. But in matters of speculation, such as theorists and statesmen deal in, one may pursue a false principle a long time before discovering its falsity by the complicated consequences to which men were formerly strangers; and when at last its falsity is found out, the authors take refuge in the opposite principle, turn round, contradict themselves, and seek their justification in a modern maxim of incomparable absurdity: in political economy, there is no inflexible rule, no absolute principle. Let us see, then, if these two opposite principles which I have just described do not predominate by turns, the one in practical industry, the other in industrial legislation. I have already noticed the saying of M. Bugeaud (that "when bread is dear, agriculturists become rich"); but in M. Bugeaud are embodied two separate characters, the agriculturist and the legislator. As an agriculturist, M. Bugeaud directs all his efforts to two ends,--to save labour, and obtain cheap bread. When he prefers a good plough to a bad one; when he improves his pastures; when, in order to pulverize the soil, he substitutes as much as possible the action of the atmosphere for that of the harrow and the hoe; when he calls to his aid all the processes of which science and experiment have proved the efficacy,--he has but one object in view, viz., to diminish _the proportion of effort to result_. We have indeed no other test of the ability of a cultivator, and the perfection of his processes, than to measure to what extent they have lessened the one and added to the other. And as all the farmers in the world act upon this principle, we may assert that the effort of mankind at large is to obtain, for their own benefit undoubtedly, bread and all other products cheaper, to lessen the labour needed to procure a given quantity of what they want. This incontestable tendency of mankind once established, should, it would seem, reveal to the legislator the true principle, and point out to him in what way he should aid industry (in as far as it falls within his province to aid it); for it would be absurd to assert that human laws should run counter to the laws of Providence.
