In 1781, Condorcet anonymously published a pamphlet entitled ''Reflections on Negro Slavery'' ({{lang|fr|Réflexions sur l'esclavage des nègres}}), in which he denounced [[slavery]].<ref>{{cite book|title=A History of Sociological Analysis|chapter-url=https://archive.org/details/historyofsociolo0000bott|chapter-url-access=registration|last=Bierstedt|first=Robert|publisher=Basic Books|year=1978|isbn=0465030238|page=[https://archive.org/details/historyofsociolo0000bott/page/19 19]|chapter=Sociological Thought in the Eighteenth Century|editor1-last=Bottomore|editor1-first=Tom|editor2-first=Robert|editor2-last=Nisbet}}</ref> In 1786, Condorcet worked on ideas for the [[Derivative|differential]] and [[integral calculus]], giving a new treatment of [[infinitesimal]]s&nbsp;– a work which apparently was never published. In 1789, he published ''Vie de Voltaire (1789)'', which agreed with [[Voltaire]] in his opposition to the [[Roman Catholic Church|Church]]. In the same year he was elected as president of the [[Society of the Friends of the Blacks]] and lived in an apartment at [[Hôtel des Monnaies, Paris]], across the Louvre.<ref>{{cite web | url=https://revolution.chnm.org/d/339 | title=Roster of Membership in the Society of Friends of Blacks, 1789 | year=1789 }}</ref> In 1791, Condorcet, along with Sophie de Grouchy, [[Thomas Paine]], [[Pierre Étienne Louis Dumont|Etienne Dumont]], [[Jacques Pierre Brissot|Jacques-Pierre Brissot]], and Achilles Duchastellet published a brief journal titled ''Le Républicain'', its main goal being the promotion of republicanism and the rejection of constitutional monarchy. The journal's theme was that any sort of monarchy is a threat to freedom no matter who is leading and that liberty is freedom from domination.<ref>{{Cite journal|last=Berges|first=Sandrine|year=2015|title=Sophie de Grouchy on the Cost of Domination in the Letters on Sympathy and Two Anonymous Articles in Le Républicain|journal=Monist|volume=98|pages=102–112|via=Florida International University|doi=10.1093/monist/onu011|hdl=11693/12519|hdl-access=free}}</ref>

In 1795, Condorcet's book ''[[Sketch for a Historical Picture of the Progress of the Human Mind]]'' was published after his death by his wife Sophie de Grouchy. It dealt with theoretical thought on perfecting the human mind and analyzing intellectual history based on social arithmetic.<ref>{{Cite journal|last=Roman|first=Hanna|date=2015-02-06|title=Conjecturing a New World in Condorcet's Esquisse d'un tableau historique des progrès de l'esprit humain|journal=MLN|volume=129|issue=4|pages=780–795|doi=10.1353/mln.2014.0077|s2cid=162365727|issn=1080-6598}}</ref> [[Thomas Malthus]] wrote ''[[An Essay on the Principle of Population]]'' (1798) partly in response to Condorcet's views on the "''perfectibility of society''."
