[74] _Socialisme et philosophie_ by ANTONIO LABRIOLA. Paris, Giard et Brière, 1899, see pp. 207-224. Postscript to the French edition. [75] See chap. III. [76] Like an impenitent sinner I shall come back to this distinction, which is essential for the solid foundation of the principles of economics, and the evil effects of whose neglect are apparent in the discourses of economists. [77] I write _equivalence_ because Marx writes thus, and because for the present question this other is quite irrelevant: viz. whether the relation of value can be expressed in the mathematical form of a relation of equivalence. But, for my part, and I follow the hedonists in this; I deny entirely that the relation of value is a relation of equivalence. The proof of this has already been supplied by others, and there is no occasion to repeat it. [78] See CROCE _Giambattista Basile e il 'Cunto de li Cunti_,' Naples, 1891; _Ricerche ispano-italiane_, series I, last paragraph, (_Atti dell' Acc. Pontan_; vol. xxviii, 1898); _I predicatori italiani del seicento e il gusto spagnuolo_, Naples, Pierro, 1899; _I trattatisti italiani del 'concettismo' e Baltasar Gracian_ (_Atti dell' Acc. Pontan_; vol. xxix, 1899). [79] LABRIOLA--who reproduces Marx's style very well here and there in his own--writes in his essay on '_Das Kommunistische Manifest_,' 2nd Ed., p. 79. 'The _Manifesto_ ... does not shed tears over nothing. The tears of things have already risen on their feet of themselves, like a spontaneously vengeful force.' The _tears_ which rise _on their feet_ may make the hair rise _on the head_ of a man of moderate taste; but the expression, although violently imaginative, is not in seventeenth century style. [80] Als Hegel auf dem Todbette lag, sagte er:--Nur einer hat mich verstanden! Aber gleich darauf fügte er verdriesslich hinzu. Und der hat mich auch nicht verstanden!' (_Heine. Zur Geschichte der Religion und Philosophie in Deutschland._ Bk. III). [81] 'Now, if my map shows me true, we are not far from the sight of our haven....' (Ariosto, _Orlando Furioso_.)
