Jules Barthélemy-Saint-Hilaire (19 August 1805 – 24 November 1895) was a French philosopher, journalist, statesman, and possible illegitimate son of Napoleon I of France.
Biography
Jules was born in Paris. Marie Belloc Lowndes, in the second volume of her autobiography Where Love and Friendship Dwelt (1943), made claims regarding his paternity. He was reportedly ashamed of and did not talk about it. Lowndes did not say who his mother was.
In his early years he worked for the Ministry of Finance (1825–1828), and was an active journalist. From 1826 to 1830 he opposed the policies of Charles X of France in Le Globe. At the revolution of 1830 he signed the protestation of the journalists on 28 July 1830.
After 1830, he contributed to different newspapers, Le Constitutionnel, Le National and Le Courrier français until 1833, when he gave up politics in order to devote himself to the history of ancient philosophy, undertaking a translation of Aristotle, which occupied him the greater part of his life. The reputation he gained from this work won him the chair of ancient philosophy at the Collège de France (1838) and a seat at the Academy of Moral and Political Science (1839).
He died in Paris in 1895. His principal works, besides the translation of Aristotle and a number of studies connected with the same subject, are Des Védas (1854), Du Bouddhisme (1856) and Mahomet et le Coran (1865).
