The first and most important truth illustrated in the table is, that, from the division of value into labour and profits, and the mode in which profits are always estimated, it follows necessarily, that the quantity of labour required to produce the wages of a given number of men, with the addition of the profits upon these advances estimated in labour, must always be exactly the same as the quantity of labour which the wages will command, and must together always make up the constant quantity which appears in the seventh column. But the quantity of labour required to produce the varying wages of ten men is, under the different circumstances supposed, very different, as appears in the fifth column; and it is obvious, that while the numbers in the fifth column vary, the numbers in the seventh column, or the quantity of labour and profits united, cannot be constant, unless, as the quantity of labour required to produce the wages of ten men increases, the quantity of profits estimated in labour diminishes exactly in the same degree. But this, from what has before been stated, must, under the circumstances supposed, be the case. And it follows, that if the natural value of a commodity may be estimated by the labour and profits of which it is composed, the natural value of the corn wages of a given number of men must always be the same. But such wages, according to the postulate with which we commenced, must necessarily be equal to the quantity of labour for which they will exchange. Consequently the value of a given quantity of labour must, under every variety which can take place in the fertility of the soil and the corn wages of labour, be always constant. It is, however, of the greatest importance to remark, that an exact balance of labour, and of profits estimated in labour, so as to yield always a constant quantity, cannot take place in the production of any one commodity or given portion of a commodity; because any one commodity, or given portion of a commodity, is liable to vary in relation to labour, and such variation will either increase or decrease the amount of the labour and profits united. It is only the varying wages of a given number of men bearing, as the terms imply, a constant relation to labour, which, under any changes in the quantity of labour required to produce them, can still continue of the same natural value. And it is precisely this necessary constancy in the natural value of the varying corn wages of labour, which renders the labour which a commodity will command, a standard measure both of its natural and exchangeable value.
