Durkheim sought to create one of the first rigorous scientific approaches to social phenomena. Along with Herbert Spencer, he was one of the first people to explain the existence and quality of different parts of a society by reference to what function they served in maintaining the quotidian (i.e. by how they make society "work"). He also agreed with Spencer's organic analogy, comparing society to a living organism. Thus his work is sometimes seen as a precursor to functionalism. Durkheim also insisted that society was more than the sum of its parts.
