Edouard Le Roy

Who was Edouard Le Roy?

Édouard Louis Emmanuel Julien Le Roy was a French philosopher and mathematician.

Le Roy was received at the École Normale Supérieure in 1892, and at the agrégation in mathematics in 1895. He became Doctor in Sciences in 1898, taught in several high schools, and became in 1909 professor of mathematics at the Lycée Saint-Louis in Paris.

From then on, Le Roy took an important interest in philosophy and metaphysics. A friend of Teilhard de Chardin and Henri Bergson's closer disciple, he succeeded to him at the College of France and, in 1945, at the Académie française. In 1919, Le Roy was also elected member of the Académie des Sciences morales et politiques.

Le Roy especially interested himself to the relations between science and morality. Along with Henri Poincaré and Pierre Duhem, he supported a conventionalist thesis on the foundation of mathematics. Although a fervent Catholic, he extended this conventionalist theory to revealed truths, which did not, according to him, withdraw any of their strength. He rejected in the domain of religion dogmas, abstract reasonings and speculative theology in favour of instinctive faith, heart and sentiment.
