Antoine Augustin Cournot (1801 - 1877) was a mathematician, philosopher,
economist and educator (Feller 1961; Etudes 1978). Here, I discuss his
contribution of 1843 reprinted in 1984 (Paris, Libraire J. Vrin) as vol.
1 of his Oeuvres Complètes complete with an Introduction and Commentary
by B. Bru. The Preface begins by an explanation: Cournot wished to make
assessable his subject to those unacquainted with the higher chapters of
mathematics. In § 123 he even repeated the formulation of the
Pythagorean proposition (excluded in the translation) and in § 69 he
says that he adduced a table (Kramp's table) of a certain function (of
the exponential function of a negative square) but he did not provide
its analytical expression.
