Revolution and Condorcet's role as a central figure in the Enlightenment. His coffin, however, was empty as his remains, originally interred in the common cemetery of Bourg-la-Reine, were lost during the nineteenth century. Family In 1786 Condorcet married Sophie de Grouchy, who was more than twenty years his junior. Sophie, reckoned one of the most beautiful women of the day, became an accomplished salon hostess as Madame de Condorcet, and also an accomplished translator of Thomas Paine and Adam Smith. She was intelligent and well educated, fluent in both English and Italian. The marriage was a strong one, and Sophie visited her husband regularly while he remained in hiding. Although she began proceedings for divorce in January 1794, it was at the insistence of Condorcet and Cabanis, who wished to protect their property from expropriation and to provide financially for Sophie and their young daughter, Louise 'Eliza' Alexandrine. Condorcet was survived by his widow and four-year-old Eliza. Sophie died in 1822, never having remarried, and having published all her husband's works between 1801 and 1804. Her work was carried on by Eliza, wife of former United Irishman Arthur O'Connor. The Condorcet-O'Connors published a revised edition between 1847 and 1849. Gender equality Condorcet's work was mainly focused on a quest for a more egalitarian society. This path led him to think and write about gender equality in the Revolutionary context. In 1790, he published "Sur l'admission des femmes au droit de cité" ("On the Admission of Women to the Rights of Citizenship") in which he strongly advocated for women's suffrage in the new Republic as well as the enlargement of basic political and social rights to include women. One of the most famous Enlightenment thinkers at the time, he was one of the first to make such a radical proposal. 'The rights of men stem exclusively from the fact that they are sentient beings, capable of acquiring moral ideas and of reasoning upon them. Since women have the same qualities, they necessarily also have the same rights. Either no member of the human race has any true rights, or else they all have the same ones; and anyone who votes against the rights of another, whatever his religion, colour or sex, automatically forfeits his own.' A visionary, he identified gender as a social construction based on perceived differences in sex and rejected biological determinism as being able to explain gender relations
