Sismondi here lost his thread plainly because he tried to establish a connection between the capital concept and the material aspects of social reproduction. Earlier, so long as he was concerned with the individual capitalist, he listed means of subsistence for the workers together with means of production as component parts of capital—again a mistake in view of the material aspects of the reproduction of individual capitals. Yet as soon as he tries to focus the material foundations of social reproduction and sets out to make the correct distinction between consumer goods and means of production, the concept of capital dissolves in his hands.

However, Sismondi well knows that the means of production are not the sole requisites for production and exploitation; indeed, he has the proper instinct that the core of the relation of exploitation is the very fact of exchange with living labour. Having just reduced capital to constant capital, he now immediately reduces it exclusively to variable capital:

‘When the farmer has put in reserve all the corn he expects to need till the next harvest, he will find a good use for the surplus corn: he will feed what he has left over to other people who are going to work for him, till his land, spin and weave his hemp and wool, etc.... By this procedure, the farmer converts a part of his income into capital, and in fact, this is the way in which new capital is always formed.... The corn he has reaped over and above what he must eat while he is working, and over and above what he will have to sow in order to maintain the same level of exploitation, is wealth which he can give away, squander and consume in idleness without becoming any poorer; it was income, but as soon as he uses it to feed producers, as soon as he exchanges it for labour, or for the fruits to come from the work of his labourers, his weavers, his miners, it is a permanent value that multiplies and will no longer perish; it is capital.’[165]

Here there is some grain mixed up with quite a lot of chaff. Constant capital seems still required to maintain production on the old scale, although it is strangely reduced to circulating capital, and although the reproduction of fixed capital is completely ignored. Circulating capital apparently is also superfluous for the expansion of reproduction, for accumulation: the whole capitalised part of the surplus value is converted into wages for new workers who evidently labour in mid-air, without material means of production. The same view is expressed even more clearly elsewhere:

‘When the rich man cuts down his income in order to add to his capital, he is thus conferring a benefit on the poor, because he himself shares out the annual product; and whatever he calls income, he will keep for his own consumption; whatever he calls capital, he gives to the poor man to constitute an income for him.’[166]

Yet at the same time Sismondi gives due weight to the ‘secret of profit-making’ and the origin of capital. Surplus value arises from the exchange of capital for labour, from variable capital, and capital arises from the accumulation of surplus value.

With all this, however, we have not made much progress towards a distinction between capital and income. Sismondi now attempts to represent the various elements of production and income in terms of the appropriate parts of the aggregate social product.

‘The employer of labour, as also the labourer, does not use all his productive wealth for the sowing; he devotes part of it to buildings, mills and tools which render the work easier and more productive, just as a share of the labourer’s wealth had been devoted to the permanent work of making the soil more fertile. Thus we see how the different kinds of wealth successively come into being and become distinct. One part of the wealth accumulated by society is devoted by every one who possesses it to render labour more profitable by slow consumption, and make the blind forces of nature execute the work of man; this part is called fixed capital and comprises reclaiming, irrigation, factories, the tools of trade, and mechanical contrivances of every description. A second part of wealth is destined for immediate consumption, to reproduce itself in the work it gets done, to change its form, though not its value, without cease. This part is called circulating capital and it comprises seed, raw materials for manufacture, and wages. Finally, a third part of wealth becomes distinguishable from the second: it is the value by which the finished job exceeds the advances which had to be made: this part is called income on capitals and is destined to be consumed without reproduction.’[167]

After this laborious attempt to achieve a division of the aggregate social production according to incommensurable categories, fixed capital, circulating capital, and surplus value, Sismondi soon shows unmistakable signs that he means constant capital when he speaks of fixed capital, and variable capital when he speaks of circulating capital. For ‘all that is created’, is destined for human consumption, though fixed capital is consumed ‘mediately’ while the circulating capital ‘passes into the consumption fund of the worker whose wage it forms’.[168] Thus we are a little nearer to the division of the social product into constant capital (means of production), variable capital (provisions for the workers) and surplus value (provisions for the capitalists). But so far Sismondi’s explanations are not particularly illuminating on the subject which he himself describes as ‘fundamental’. In this welter of confusion, at any rate, we cannot see any progress beyond Adam Smith’s ‘massive thought’.

Sismondi feels this himself and would clarify the problem ‘by the simplest of all methods’, sighing that ‘this movement of wealth is so abstract and requires such great power of concentration to grasp it properly’.[168] Thus again we put on blinkers with a focus on Robinson [Crusoe], who in the meantime has changed to the extent that he has produced a family and is now a pioneer of colonial policy:
