[211] In fact, here again, Say's only achievement lies in having given a pompous and dogmatic form to an idea that others had expressed before him. As Bergmann points out, in his _Theory of Crises_ (Stuttgart, 1895), the work of Josiah Tucker (1752), Turgot's annotations to the French pamphlets, the writings of Quesnay, Dupont de Nemours, and of others contain quite similar observations on a natural balance, or even identity, between demand and supply. Yet the miserable Say, as Marx once called him, claims credit as the evangelist of harmony for the great discovery of the '_théorie des débouchés_', modestly comparing his own work to the discovery of the principles of thermo-dynamics, of the lever, and of the inclined plane. In the preface and table of contents, e.g. to the 6th edition of his _Traité_ (1841, pp. 51, 616) he says: 'The theory of exchange and of vents, such as it is developed in this work, will transform world politics.' The same point of view is also expounded by James Mill in his 'Commerce Defended' of 1808, and it is he whom Marx calls the real father of the doctrine of a natural equilibrium between production and demand.

Say indicts Sismondi as the arch-enemy of bourgeois society in the following ranting peroration: 'It is against the modern organisation of society, an organisation which, by despoiling the working man of all property save his hands, gives him no security in the face of a competition directed towards his detriment. What! Society despoils the working man because it ensures to every kind of entrepreneur free disposition over his capital, that is to say his property! I repeat: there is nothing more dangerous than views conducive to a regulation of the employment of property' for 'hands and faculties ... are also property' (ibid., p. 30).
