I will, to the best of my power, state my objections to your arguments respecting the measure of value. You have yourself stated, as an objection to my view on this subject, that a commodity produced with labour and capital united, cannot be a measure of value for any other commodities than such as are produced precisely under the same circumstances, and in this I have agreed that you are substantially correct. If all commodities were produced in one day and by labour only without the assistance of capital, they would vary in proportion as the quantity of labour employed on their production increased or diminished. If the same quantity of labour was constantly employed on the production of money, money would be an accurate measure of absolute value, and, if shrimps or nuts or any other thing rose or fell in such money, it would only be because more or less labour was employed in procuring them. Under such circumstances every commodity which was the produce of a day's labour would naturally command a day's labour, and therefore the value of a commodity would be in proportion to the quantity of labour which it would command. But, though such a money would measure accurately the value of every commodity produced under circumstances exactly similar, it would not be an accurate measure of the value of other commodities produced with a large quantity of capital, employed for a length of time. In the case just supposed a quantity of shrimps would be as accurate a measure of value as a quantity of money produced by the same quantity of labour; but, when capital is employed and cloth is the product of labour and capital, you justly say that cloth is not a correct measure of the value of shrimps and of silver, picked up by labour alone, on the sea shore; and yet with singular inconsistency, as I cannot help thinking, you contend that the shrimps and the silver, picked up by labour alone on the sea shore, are accurate measures of the value of cloth. If you are right, then must cloth be also an accurate measure of value, because the thing measured must be as good a measure as the thing with which you measure. When I say that £4 and a quarter of wheat are of the same value, I can measure other values by the quarter of wheat as well as by the £4. You say: 'It is conceded that, when labour alone is concerned in the production of commodities, and there is no question of time, both the absolute and exchangeable values of such commodities may be accurately measured by the quantity of labour employed upon them.' Nothing can, I think, be more correct, and it is perfectly accordant with what I have been saying. Your mistake appears to me to be this: you show us that under certain conditions a certain commodity would be a measure of absolute value, and then you apply it to cases where the conditions are not complied with, and suppose it to be a measure of absolute value in those cases also. You appear to me, too, to deceive yourself when you think you prove your proposition, because your proof only amounts to this, that your measure is a good measure of exchangeable value but not of absolute value. You say: 'If the accumulated and immediate labour worked up in a commodity be of any assumed value, £100 for instance, and the profits of the value of £20, including the compound profits upon the labour worked up in the materials, the whole will be of the value of £120. Of this value 1/6 only belongs to profits, the rest or 5/6 may be considered as the product of pure labour.' This is quite true, whether we value the commodity by the quantity of labour actually employed upon it, by the quantity which it will command when brought to market, or by the quantity of money, or any other commodity, for which it is exchanged; 5/6, in all cases, will belong to the workmen and 1/6 to the master. 'Consequently the value of 5/6 of the produce is determined by the quantity of labour employed on the whole; and the value of the whole produce by the quantity of labour employed upon it with the addition of 1/6 of that quantity.' This is really saying no more than that, when profits are one sixth of the value of the whole commodity (in which no rent enters), the other 5/6 go to reward the labourers, and that the portion so going to the labourers may itself be resolved into labour and profits in the same proportion of 5 and 1. Five men produce six pieces of cloth, of which 5 are paid to them, the men; if profits fall one half, the men will receive 5½ pieces, and then you say the cloth is of less value; but in what medium? In labour, you answer. You appear to me to advance a proposition that cloth is of less value when it will exchange for less labour, and to prove it by showing the fact, merely, that it actually does exchange for less labour.
You say: 'But, when labour is concerned, it follows from what has been conceded that the value of the produce is determined by the quantity of labour employed upon it.' By value here you mean absolute value; and then you immediately apply this measure of absolute value, which is only conceded in a particular case, to a general proposition, and say 'consequently;' consequently on what? On this particular case; 'consequently the value of 5/6 of the produce is determined by the quantity of labour employed on the whole,' that is to say 'consequently the quantity of labour which 5/6 of the produce will command is determined by the quantity of labour employed on the whole;' the same is true, in the same sense, of 5/6, 5/7, 5/8, 5/9 or of any other proportions in which the whole may be divided. My only object has been to show, and, if I am not mistaken, I have succeeded in showing, that a measure of value, which is only allowed to be accurate in a particular case where no capital is employed, is arbitrarily applied by you to cases where capital and time necessarily enter into the consideration.
I fear I have been guilty of many repetitions. I shall not regret it, however, if I have made myself understood.

Note.—On 12th June, 1822, in one of Ricardo's most important speeches on Resumption (afterwards published as a pamphlet), he speaks of those who propose to make Corn, on a ten years' average, the standard of value instead of money. To prove gold more variable than corn, they and their authorities, Locke and Adam Smith are (he says) obliged to begin by supposing gold invariable. 'Unless the medium in which the price of corn is estimated could be asserted to be invariable in its value, how could corn be said not to have varied in relative value? If they must admit the medium to be variable—and who could deny it?—then what became of the argument?' Nothing is more difficult than to ascertain the variations in the value of money: 'To do so with any accuracy we should have an invariable measure of value; but such a measure we never had nor ever can have.' (Cf. Pol. Econ. and Tax. ch. i. § 7, Works, p. 28.) But we can speak with accuracy of depreciation; we can see to it that the standard is always the same standard, and that our currency conforms to it, even if the standard itself may vary in value.

LXXXV.
London, 13 July, 1823.
My dear Malthus,
McCulloch and I did not settle the question of value before we parted,—it is too difficult a one to settle in a conversation; I heard everything he had to urge in favour of his view, and promised, during my holiday, to bestow a good deal of consideration on it. He means exactly what you say;—he does not contend that commodities exchange for each other according to the quantity of labour actually worked up in them, but he constitutes a commodity the general measure, by which he estimates the value of all others. A pipe of wine kept for three years has no more labour worked up in it than a pipe of wine kept for a day, but he says the additional value on account of time must be estimated by the accumulations which a like amount of capital actively employed in the support of labour would make in the same time. An oak-tree which has been growing for 200 years has very little labour actually worked up in it, but its value is to be estimated by the accumulated capital which the original labour employed would give in the same time. He and you in fact differ as to your original measure. I think he could not give any other good reason for choosing a medium which requires labour and capital to produce it, rather than one which requires labour only, excepting that commodities in general require the combination of the two, and that a measure, to have any claim to be even an approximation to an accurate one, should itself be produced under circumstances somewhat similar to the commodities which it is to measure. If all things required precisely the same quantities of capital and labour, and for the same length of time, to produce them, any one of them would be an accurate measure of the rest; but this is not the case; the conditions admit of infinite variety, and therefore whichever we choose it can only be an approximation to truth, and we are bound to give good reasons for preferring it.
I should, indeed, be wanting in candour if I refused to admit that my money measure would not measure the quantity of labour worked up in commodities. I have admitted it over and over again. I am also ready to admit that your money measure will measure exactly the quantity of labour and profits together of which commodities are composed, but so will my money measure. Neither of them will measure the quantity of labour alone worked up in commodities, but they will both measure the quantity of labour and profits together of which commodities are composed. Suppose gold always to require the same quantity of labour, for one year, before it can be brought to market, will you say that all variations in wages and profits may not be estimated in this medium? You would indeed say that many of those variations would be ascribable to the variations in the value of the medium, and not to any alteration in the value of the thing measured, because you do not think that it is any proof of invariability in a commodity that it requires always the same quantity of labour, and the same duration of time to produce it. If I allow the justice of your objection, I am at liberty to apply the same to your medium. The same quantity of labour applied for a day will always produce the same given quantity of gold; gold is therefore an invariable measure, you say. I find this gold vary in relation to another commodity which always requires the same quantity of labour and capital to produce it; you say it is never the gold but it is always the commodity which varies, and, when you are asked why, you answer because labour never varies. Double the quantity of labour in a country or diminish it one half, always leaving the funds which are to employ it at precisely the same amount, and you tell us, notwithstanding the condition of the labourer is in the one case a very distressed one, in the other a very prosperous one, that the value of his labour has not varied. I cannot subscribe to the justness of this language. The question is whether you are right, not whether I am wrong. Suppose that a man in India could pick up in a day precisely the same quantity of gold as in England, and that all trade in provisions were forbid between the two countries. The small quantity of rice and clothing in India which are necessary for the support of a labourer would be of precisely the same value as the quantity of wheat and clothing necessary for a labourer in England. But this would not long continue. All manufactured commodities would be of a high comparative money value in India, and consequently we should export manufactured commodities and import gold; the reward of a labourer in England would come to be a much larger quantity of gold than he could actually pick up here. No gold would be then obtained in England but by means of importation. Under these circumstances you would say that money was of a low value in England, and you would be correct if all men agreed to constitute labour the measure of value; but in this they do not agree, and, as we should find that at the very moment that gold was low, relatively to labour, in England, it was high relatively to manufactured commodities of every description, with which in fact gold would be purchased from India, if we took these commodities for the measure, we should be bound to say that gold was cheap in England and dear in India. You must remember that the point in dispute is whether labour be the correct measure of value; you must not then take the fact for granted, and then offer it as a proof of your correct conclusion.
