Jules Lachelier

Jules Esprit Nicolas Lachelier (27 May 1832 – 26 January 1918) was a French philosopher, most known for his contributions to French spiritualism and his influence on modern French philosophy. He developed a system of rational idealism and was a key figure in the neo-spiritualist movement in French philosophy. His work focused on the relationship between thought and reality, and he attempted to provide a basis for induction in a philosophy of nature. Lachelier's ideas had a significant impact on other philosophers, including Émile Boutroux, Victor Brochard, and Henri Bergson.
