supposed of equal labour to that of producing an ounce of Silver" (p. 66).
This is, to begin with, the "real and not an imaginary way of computing the prices of Commodities" (p. 66). 1 The second point which has now to be examined is the value of labour: "for then the Law that appoints such Wages were ill made, but which would allow the Labourer but just wherewithal to live; for if you allow double, then he works but half so much as he could have done, and otherwise would; which is a loss to the Publick of the fruit of so much labour" (page 64).
This passage is to be understood as follows: If the worker were to get for six hours' labour the value of six hours, he would get twice as much as he now gets when he is given the value of six hours' labour (for twelve hours' labour). He will then work only six hours. The value of labour is therefore determined by the necessary means of subsistence. The worker is impelled to produce surplus value and to perform surplus labour only by the fact that he is forced to use the whole of the labour power within his capacity in order to get for himself just as much as he needs to live. The cheapness or dearness of his labour, however, is determined by two factors: natural productivity, and the standard of expenditure (needs) conditioned by the climate: "Natural dearness and cheapness depends upon the few or more hands requisite to necessaries of Nature: As Corn is cheaper where one man produces Corn for ten, then where he can do the like but for six; and withal, according as the ____________________ | 1 | In Petty Political Anatomy of Ireland, London, 1672 (the edition here quoted is that of 1682), he says however: "Wherefore the days food of an adult Man, at a Medium, and not the days labour, is the common measure of Value, and seems to be as regular and constant as the value of fine Silver.... Wherefore I valued an Irish Cabbin at the number of days food, which the Maker spent in building of it" (p. 65). This has quite a Physiocratic ring. "That some Men will eat more than others, is not material, since by a days food we understand 1/100 part of what 100 of all Sorts and Sizes will eat, so as to Live, Labour, and Generate" (p. 64). But what Petty seeks here in the Irish statistics is not the immanent measure of values, but the measure of values in the sense that money is a measure of values. | -16- |
