It appears, then, that human industry 13 concerned, more or less, in the production of almost every thing that we consume, or that 1s of any utility for the support, the comfort, or the convenience of life; it follows that whatever cause may afect that industry in such a manner as to inﬂuence the quantity, the quality, or the nature of its productions, must necessarily par take of the importance of that industry itself. It IS necessary here to point out a distinction which has been wholly overlooked by political economists, but which nevertheless 1s essential to a knowledge of the true nature of the science of political economy. We mean the distinction between the causes which inﬂuence industry, and those which inﬂuence production. The former are to the latter as a part to the whole. Whatever influences industry, inﬂuences production, but it does not follow, that, whatever in fluences production, influences industry.
