Pierre Laffitte

Pierre Laffitte, born on February 21, 1823, in Béguey, Gironde, was a prominent French positivist philosopher. He resided in Paris, where he worked as a mathematics teacher and became a devoted disciple of Auguste Comte. Following Comte's death, Laffitte was appointed as his literary executor. In the subsequent schism within the Positivist movement, Laffitte led the faction that adhered to the full Comtian doctrine, while another group followed Émile Littré, who rejected Comte's concept of the 'religion of humanity'. From 1853 onwards, Laffitte delivered Positivist lectures in Paris. He authored notable works such as 'Les Grands Types de l'humanité' (1875) and 'Cours de philosophie première' (1889). In recognition of his contributions to the history of science, he was appointed to a newly established chair at the Collège de France in 1893. His influence was instrumental in the erection of a statue of Auguste Comte in the Place de la Sorbonne in 1902. Laffitte also played a role in international positivist outreach; in 1877, he led a delegation to Constantinople to promote positivist principles. Furthermore, he initiated the first "subscription for the erection of a Mosque in Paris, in honor of Islam" through the journal 'Revue Occidentale', which ultimately led to the construction of the Great Mosque of Paris. Pierre Laffitte passed away in Paris on January 4, 1903.
