If, however, by value, Mr. Ricardo had meant _exchangeable_ value, his proposition would still have been remote from the truth. Profits depend no more upon the exchangeable value of the labourer's remuneration, than upon its quantity. The truth is, that by the exchangeable value is meant the quantity of commodities which the labourer can purchase with his wages; so that when we say the exchangeable value of wages, we say their quantity, under another name. Mr. Ricardo, however, did not use the word value in the sense of exchangeable value. Occasionally, in his writings, he could not avoid using the word as other people use it, to denote value in exchange. But he more frequently employed it in a sense peculiar to himself, to denote cost of production; in other words, the _quantity of labour_ required to produce the article; that being his criterion of cost of production. Thus, if a hat could be made with ten days' labour in France and with five days' labour in England, he said that the value of a hat was double in France of what it was in England. If a quarter of corn could be produced a century ago with half as much labour as is necessary at present, Mr. Ricardo said that the value of a quarter of corn had doubled. Mr. Ricardo, therefore, would not have said that wages had risen, because a labourer could obtain two pecks of flour instead of one, for a day's labour; but if last year he received, for a day's labour, something which required eight hours' labour to produce it, and this year something which requires nine hours, then Mr. Ricardo would say that wages had risen. A rise of wages, with Mr. Ricardo, meant an increase in the cost of production of wages; an increase in the number of hours' labour which go to produce the wages of a day's labour; an increase in the _proportion_ of the fruits of labour which the labourer receives for his own share; an increase in the ratio between the wages of his labour and the produce of it. This is the theory: the reasoning, of which it is the result, has been given in the preceding paragraphs. Some of Mr. Ricardo's followers, or more properly, of those who have adopted in most particulars the views of political economy which his genius was the first to open up, have given explanations of Mr. Ricardo's doctrine to nearly the same effect as the above, but in rather different terms. They have said that profits depend not on _absolute_, but on _proportional_ wages: which they expounded to mean the proportion which the labourers _en masse_ receive of the total produce of the country.
