A similar tendency shows itself in what has been written on the subject by Sombart, in 1894, by Engels in 1895, by myself in 1896, by Sorel in 1897, by myself more at length in 1897, and again by Sorel in June of last year (1898).[82] Certainly truth and falsehood cannot be decided by external signs, the intellect being the only judge of them, and a judge who allows scope for infinite appeals. But nevertheless it is natural that under the circumstances pointed out above, a feeling of hope and confidence must arise that the discussion is about to be closed, that the problem is at length ripe for solution.

II

Meaning of phrase crisis In Marxianism: Sorel's view of equivalence of value and labour mostly in agreement with view put forward above: An attempt to examine profits independently of theory of value: Is not possible: Surplus product same as surplus value.

I think it opportune, however, to return to those elaborations of Sorel, which Labriola summarily judges with such severity, in order to make some remarks about them, not in refutation but in support, and to explain a certain point where there may seem to be disagreement between us, which perhaps has no reason to exist.

But here I may be allowed to make a remark. Labriola is also waging war with Sorel: his book Discorrendo, etc., arising out of a series of friendly letters to Sorel, which I undertook to edit in Italy, is published in French with an appendix directed against me, and a preface directed against Sorel. The ground of the quarrel is especially in connection with the so-called crisis in Marxism.

Now if the crisis in Marxism be understood as the assertion of the need for a revision and correction of the scientific ideas, of the historical beliefs, of the material of observed facts, which are current in Marxian literature, well and good: in such a crisis I too believe. If it means also a change in the programmes and practical methods, I neither agree nor disagree, having never concerned myself with the subject in dispute. If the danger is really existent the apprehension of which seems to obsess and disturb Labriola, that a crisis in Marxism of whatever kind, or the commencement of it, may be neutralised by those to whose interest it is to lead astray and scatter the labour movement, then provideant consules. But whether there be crisis or no crisis, whether purely scientific or also practical, whether apprehensions are well-founded or imagined and exaggerated, all these things have no connection with the questions raised by me, which relate to the erroneousness of this or that theoretical or historical statement of Marxism, and the way in which this or that must be understood in order to be regarded as true. This is my standpoint and on this ground alone I admit discussion. I may be mistaken, but this must be proved to me. But if, on the contrary, the only answer vouchsafed to me is that the crisis in Marxism results from the international reaction, of which ingenious critics are taking advantage, I shall be left it is true, somewhat bewildered; but I shall not on this account be convinced that the theory of value is true, in the burlesque sense, for example, in which it is expounded by Stern in his well-known propagandist booklet.

Sorel at first supposes,[83] wittily enough, that Marx had built up different economic spheres, the first of which (that of labour-value) is the simplest; the second, including the phenomenon of an average rate of profit, and the creation of cost of production, is more complex, and the third, in which is observed the effect of rent of land, is still more complex. In passing from the simple to the more complex sphere, we should find again the laws of the preceding one, modified by the new data introduced, which would have given rise to new phenomena.

In his second article he abandons this interpretation, being convinced that Marx's ideal construction does not aim at supplying a complete explanation of the phenomena of economics by means of the increasing complexity of his combinations. And, in my opinion, he did well to abandon it; not only for the excellent reason stated by him, that Marx's inquiry does not include an entire system of economics, but also because the process suggested by him does not explain why Marx, in analysing the economic phenomena of the second or third sphere, ever used concepts whose place was only in the first one. It does not explain what I have called the eliptical comparison, and herein lies the difficulty of Marx's work, or rather of the literary statement of his thought. If the correspondence between labour and value is only realized in the simplified society of the first sphere, why insist on translating the phenomena of the second into terms of the first? Why give the name transformation of surplus value to what makes its appearance as the natural economic result of capital which must have (from its very nature as capital) a profit? Does Marx offer an explanation connecting ground and consequence, or does he not rather draw a parallel between two different phenomena, by which the diversities illuminating the origins of society are set in relief?

But Sorel now advances to precisely this conclusion, borrowing a happy phrase from his first article: that Marx's work is not intended to explain by means of laws analogous to physical laws, but only to throw partial and indirect light on economic reality.

The method which Marx employs in his inquiry, says Sorel, is a metaphysical instrument; he makes a metaphysics of economics. This expression may be satisfactory or not, according to the different meanings given to the word metaphysics; but the idea is accurate and true. Marx builds an ideal construction which helps him to explain the conditions of labour in capitalist society.
