Vie de Monsieur Turgot …

First edition, an uncut copy in wrappers, of the sole example of Condorcet’s economic writings to employ mathematics. Condorcet’s use of ‘the sign ∫ as a sign of summation of finite quantities’ is an ‘innovation’ in his ten-page footnoted discussion of the various ways ‘in which indirect taxation could be replaced by direct taxation and the effects of such a change’ (Theocharis, p. 65). This biography, together with that of Dupont, is the chief contemporary account of the renowned financial reformer and physiocratic sympathizer, Turgot.

Condorcet’s ‘mathematical treatment of probabilities, and his discussion of differential equations and finite differences, show an ability which might have put him in the first rank had he concentrated his attention on mathematics’ (Ball, A Short Account of the History of Mathematics, p. 388).

The work was much called for; four editions were published in 1786. This is the earliest, with a misprint in the errata: page 134 instead of 104 (identified as edition ‘A’ in Anton Gerits’ Condorcet’s Vie de Monsieur Turgot, Harvard Library Bulletin 1992-1993, vol. III, no. 4, p. 35).

Einaudi 1217; Goldsmiths’ 13128; Fisher, p. 174; INED 1186 (a later 1786 edition); Jevons, p. 278; Kress B.1032; Mattioli 746; see Theocharis, p. 65.

### LORD CHANCELLOR’S LIVES FROM THE AGE OF THE FOUNDATION OF ‘POLITICAL ECONOMY’ BROUGHAM, Lord Henry.

**Lives of men of letters and science who flourished in the time of George III … with portraits, engraved on steel.**

First edition of the first volume (1845), later edition of the second volume (dated 1847, first published 1846) of Brougham’s lives which includes Voltaire, Hume, Davy, Johnson, and Adam Smith to name a few stars in the firmament of the reign of George III, or, in Brougham’s terms, the ‘Augustan age of modern history’. He entitles it thus primarily because of the development of ‘political science’ during the period: ‘it laid the foundations, and then reared the superstructure. The science of chemistry almost entirely, [and] of political economy entirely, were the growth of this remarkable era’ (I, pp. vii-viii).
