Ο Marie-Jean Antoine Nicolas de Cartier (Marie-Jean-Antoine-Nicolas Caritat, Marquis de Condorcet, 1743-1794), known as Marquis de Condorcet, was a French mathematician, philosopher and politician, widely known for his contributions to the Enlightenment. Born in Rimbaud, France in 1743, Condorcet distinguished himself as a brilliant mathematician from an early age, which led to his membership in the Academy of Sciences. He contributed significantly to the theory of probability and developed the famous “Condorcet’s Method” for democratic decision-making.

In politics, Condorcet was an ardent supporter of democracy and equality. As a member of the Legislative Assembly during the French Revolution, he advocated the abolition of slavery and the promotion of public education.

The Marquis of Condorcet was a Freemason, with his ideas of equality, fraternity and progress largely reflecting the principles of Freemasonry. Condorcet remains a symbol of rationalism and social justice.

It is worth noting that his intellectual pursuits and political actions, such as his support for universal suffrage, abolition of slavery and educational reforms, were in harmony with the progressive and humanistic spirit often associated with Freemasonry.

In 1793, because of his confrontation with the Jacobins, a warrant of arrest was issued against him.

He died in 1794 under mysterious circumstances while in custody.
