X. If so, Phædrus, you must now acknowledge that it is a matter of perfect indifference to the hatter whether the price of hats rise or not, since he cannot under any circumstances escape the payment of the three shillings. If the price should not rise (as assuredly it will not), he pays the three shillings directly; if the price were to rise by three shillings, this implies of necessity that prices rise universally (for it would answer no purpose of your argument to suppose that hatters escaped an evil which affected all other trades). Now, if prices rise universally, the hatter undoubtedly escapes the direct payment of the three shillings, but he pays it indirectly; inasmuch as one hundred and sixteen pounds and ten shillings is now become necessary to give him the same command of labor and commodities which was previously given by one hundred pounds. Have you any answer to these deductions?

Phæd. I must confess I have none.

X. If so, and no answer is possible, then I have here given you a demonstration of Mr. Ricardo's great law: That no product of labor whatsoever can be affected in value by any variations in the value of the producing labor. But, if not by variations in its value, then of necessity by variations in its quantity, for no other variations are possible.

Phæd. But at first sight, you know, variations in the value of labor appear to affect the value of its product: yet you have shown that the effect of such variations is defeated, and rendered nugatory in the end. Now, is it not possible that some such mode of argument may be applied to the case of variations in the quantity of labor?

X. By no means: the reason why all variations in the value of labor are incapable of transferring themselves to the value of its product is this: that these variations extend to all kinds of labor, and therefore to all commodities alike. Now, that which raises or depresses all things equally leaves their relations to each other undisturbed. In order to disturb the relations of value between A, B, and C, I must raise one at the same time that I do not raise another; depress one, and not depress another; raise or depress them unequally. This is necessarily done by any variations in the quantity of labor. For example, when more or less labor became requisite for the production of hats, that variation could not fail to affect the value of hats, for the variation was confined exclusively to hats, and arose out of some circumstance peculiar to hats; and no more labor was on that account requisite for the production of gloves, or wine, or carriages. Consequently, these and all other articles remaining unaffected, whilst hats required twenty- five per cent more labor, the previous relation between hats and all other commodities was disturbed; that is, a real effect was produced on the value of hats. Whereas, when hats, without requiring a greater quantity of labor, were simply produced by labor at a higher value, this change could not possibly disturb the relation between hats and any other commodities, because they were all equally affected by it. If, by some application of any mechanic or chemical discovery to the process of making candles, the labor of that process were diminished by one third, the value of candles would fall; for the relation of candles to all other articles, in which no such abridgment of labor had been effected, would be immediately altered: two days' labor would now produce the same quantity of candles as three days' labor before the discovery. But if, on the other hand, the wages of three days had simply fallen in value to the wages of two days,—that is, if the laborer received only six shillings for three days, instead of nine shillings,—this could not affect the value of candles; for the fall of wages, extending to all other things whatsoever, would leave the relations between them all undisturbed; everything else which had required nine shillings' worth of labor would now require six shillings' worth; and a pound of candles would exchange for the same quantity of everything as before. Hence, it appears that no cause can possibly affect the value of anything—that is, its exchangeable relation to other things—but an increase or diminution in the quantity of labor required for its production: and the prices of all things whatsoever represent the quantity of labor by which they are severally produced; and the value of A is to the value of B universally as the quantity of labor which produces A to the quantity of labor which produces B.

Here, then, is the great law of value as first explained by Mr. Ricardo. Adam Smith uniformly takes it for granted that an alteration in the quantity of labor, and an alteration in wages (that is, the value of labor), are the same thing, and will produce the same effects; and, hence, he never distinguishes the two cases, but everywhere uses the two expressions as synonymous. If A, which had hitherto required sixteen shillings' worth of labor for its production, should to-morrow require only twelve shillings' worth, Adam Smith would have treated it as a matter of no importance whether this change had arisen from some discovery in the art of manufacturing A, which reduced the quantity of labor required from four days to three, or simply from some fall in wages which reduced the value of a day's labor from four shillings to three shillings. Yet, in the former case, A would fall considerably in price as soon as the discovery ceased to be monopolized; whereas, in the latter case, we have seen that A could not possibly vary in price by one farthing.

Phæd. In what way do you suppose that Adam Smith came to make so great an oversight, as I now confess it to be?

X. Mr. Malthus represents Adam Smith as not having sufficiently explained himself on the subject. "He does not make it quite clear," says Mr. Malthus, "whether he adopts for his principle of value the quantity of the producing labor or its value." But this is a most erroneous representation. There is not a chapter in the "Wealth of Nations" in which it is not made redundantly clear that Adam Smith adopts both laws as mere varieties of expression for one and the same law. This being so, how could he possibly make an election between two things which he constantly confounded and regarded as identical? The truth is, Adam Smith's attention was never directed to the question: he suspected no distinction; no man of his day, or before his day, had ever suspected it; none of the French or Italian writers on Political Economy had ever suspected it; indeed, none of them have suspected it to this hour. One single writer before Mr. Ricardo has insisted on the quantity of labor as the true ground of value; and, what is very singular, at a period when Political Economy was in the rudest state, namely, in the early part of Charles II's reign. This writer was Sir William Petty, a man who would have greatly advanced the science if he had been properly seconded by his age. In a remarkable passage, too long for quotation, he has expressed the law of value with a Ricardian accuracy: but it is scarcely possible that even he was aware of his own accuracy; for, though he has asserted that the reason why any two articles exchange for each other (as so much corn of Europe, suppose, for so much silver of Peru) is because the same quantity of labor has been employed on their production; and, though he has certainly not vitiated the purity of this principle by the usual heteronomy (if you will allow me a learned word),—that is, by the introduction of the other and opposite law derived from the value of this labor,— yet, it is probable that in thus abstaining he was guided by mere accident, and not by any conscious purpose of contradistinguishing the one law from the other; because, had that been his purpose, he would hardly have contented himself with forbearing to affirm, but would formally have denied the false law. For it can never be sufficiently impressed upon the student's mind, that it brings him not one step nearer to the truth to say that the value of A is determined by the quantity of labor which produces it, unless by that proposition he means that it is not determined by the value of the labor which produces it.

To return to Adam Smith: not only has he "made it quite clear" that he confounded the two laws, and had never been summoned to examine whether they led to different results, but I go further, and will affirm that if he had been summoned to such an examination, he could not have pursued it with any success until the discovery of the true law of Profits. For, in the case of the hats, as before argued, he would have said, "The wages of the hatter, whether they have been augmented by increased quantity of labor, or by increased value of labor, must, in any case, be paid." Now, what is the answer? They must be paid, but from what fund? Adam Smith knew of no fund, nor could know of any, until Mr. Ricardo had ascertained the true law of Profits, except Price: in either case, therefore, as Political Economy then stood, he was compelled to conclude that the fifteen shillings would be paid out of the price,—that is, that the whole difference between the twelve shillings and the fifteen shillings would settle upon the purchaser. But we now know that this will happen only in the case when the difference has arisen from increased labor; and that every farthing of the difference which arises from increased value of labor will be paid out of another fund, namely, Profits. But this conclusion could not be arrived at without the new theory of Profits (as will be seen more fully when we come to that theory); and thus one error was the necessary parent of another.
