Sismondi’s essay against Ricardo in the Revue Encyclopédique of May 1824, was the final challenge for J. B. Say, at that time the acknowledged ‘prince of economic science’ (prince de la science économique), the so-called representative, heir and populariser of the school of Adam Smith on the Continent. Say, who had already advanced some arguments against Sismondi in his letters to Malthus, countered the following July with an essay on ‘The Balance Between Consumption and Production’ in the Revue Encyclopédique, to which Sismondi in turn published a short reply. The chronology of Sismondi’s polemical engagements was thus inverse to the sequence of the opposing theories, for it had been Say who first communicated his doctrine of a divinely established balance between production and consumption to Ricardo who had in turn handed it down to MacCulloch. In fact, as early as 1803, Say, in his Traité d’Économie Politique, book i, chapter xii, had coined the following peremptory statement: ‘Products are paid for with other products. It follows that if a nation has too many goods of one kind, the means of selling them would be to create goods of a different kind.’[210]

Here we meet again the all too familiar conjuring recipe which was accepted alike by Ricardo’s school and by the ‘vulgar economists’ as the corner-stone of the doctrine of harmony.[211]

Essentially, Sismondi’s principal work constitutes a sustained polemic against this thesis. At this stage Say charges to the attack in the Revue Encyclopédique with a complete volte-face, as follows:

‘Objection may be made that, because of man’s intelligence, because of the advantage he can draw from the means provided by nature and artifice, every human society can produce all the things fit to satisfy its needs and increase its enjoyment in far larger quantities than it can itself consume. But there I would ask how it is possible that we know of no nation that is supplied with everything. Even in what rank as prospering nations seven-eighths of the population are lacking in a multitude of things considered necessities in ... I will not say a wealthy family, but in a modest establishment. The village I live in at present lies in one of the richest parts of France; yet in 19 out of 20 houses I enter here, I see but the coarsest fare and nothing that makes for the well-being of the people, none of the things the English call comforts.’[212]

There is something to admire about the effrontery of the excellent Say. It was he who had maintained that in a capitalist economy there could be no difficulties, no surplus, no crises and no misery; since goods can be bought one for the other, we need only go on producing more and more and everything in the garden will be lovely. It was in Say’s hands that this postulate had become a tenet of the doctrine of harmony, that doctrine so typical of vulgar economics, which had evoked a sharp protest from Sismondi who proved this view untenable. The latter had shown that goods cannot be sold in any quantity you like, but that a limit is set to the realisation of goods by the income of society in each case, by v + s; inasmuch as the wages of the workers are depressed to a mere subsistence level, and inasmuch as there is also a natural limit to the consumptive capacity of the capitalist class, an expansion of production, Sismondi says, must inevitably lead to slumps, crises and ever greater misery for the great masses. Say’s come-back to this is masterly in its ingenuity: If you will insist that over-production is possible, how can it happen that there are so many people in our society who are naked, hungry and in want? Pray, explain this contradiction if you can. Say, whose own position excels by contriving blithely to shrug off the circulation of money altogether by operating with a system of barter, now censures his critic for speaking of an over-abundance of products in relation not only to purchasing power but to the real needs of society, and that although Sismondi had left no doubt at all about this very salient point of his deductions. ‘Even if there is a very great number of badly fed, badly clothed and badly housed people in a society, the society can only sell what it buys, and, as we have seen, it can only buy with its income.’[213]

A little further on, Say concedes this point but alleges that his opponent has made a new mistake: ‘It is not consumers, then, in which the nation is lacking,’ he says, ‘but purchasing power. Sismondi believes that this will be more extensive, when the products are rare, when consequently they are dearer and their production procures ampler pay for the workers.’[214]

That is how Say attempts to degrade, in his own trite method of thought, or better, method of canting, Sismondi’s theory which attacked the very foundations of capitalist organisation and its mode of distribution. He burlesques the Nouveaux Principes, turning them into a plea for ‘rare’ goods and high prices, and holds up to them the mirror of an artfully flattered capitalist accumulation at its peak. If production becomes more vigorous, he argues, labour grows in numbers and the volume of production expands, the nations will be better and more universally provided for, and he extols the conditions in countries where industrial development is at its highest, as against the misery of the Middle Ages. Sismondi’s maxims he declares subversive to capitalist society: ‘Why does he call for an inquiry into the laws which might oblige the entrepreneur to guarantee a living for the worker he employs? Such an inquiry would paralyse the spirit of enterprise. Merely the fear that the authorities might interfere with private contracts is a scourge and harmful to the wealth of a nation.’[215]

Not to be diverted from his purpose by this indiscriminate apologia of Say’s, Sismondi once more turns the discussion on the fundamental issue:

‘Surely I have never denied that since the time of Louis XIV France has been able to double her population and to quadruple her consumption, as he contends. I have only claimed that the increase of products is a good if it is desired, paid for and consumed; that, on the other hand, it is an evil if, there being no demand, the only hope of the producer is to entice the consumers of a rival industry’s products. I have tried to show that the natural course of the nations is progressive increase of their property, an increase consequent upon their demand for new products and their means to pay for them, but that in consequence of our institutions, of our legislation having robbed the working class of all property and every security, they have also been spurred to a disorderly labour quite out of touch with the demand and with purchasing power, which accordingly only aggravates poverty.’[216]

And he winds up the debate by inviting the preacher of harmony to reflect upon the circumstance that, though a nation may be rich, public misery no less than material wealth is constantly on the increase, the class which produces everything being daily brought nearer to a position where it may consume nothing. On this shrill discordant note of capitalist contradictions closes the first clash about the problem of accumulation.
