The Rules of Sociological Method (1895), Durkheim expressed his will to establish a method that would guarantee sociology's truly scientific character. One of the questions raised concerns the objectivity of the sociologist: how may one study an object that, from the very beginning, conditions and relates to the observer? According to Durkheim, observation must be as impartial and impersonal as possible, even though a "perfectly objective observation" in this sense may never be attained. A social fact must always be studied according to its relation with other social facts, never according to the individual who studies it. Sociology should therefore privilege comparison rather than the study of singular independent facts. 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. Unlike his contemporaries Ferdinand Tönnies and Max Weber, he did not focus on what motivates the actions of individuals (an approach associated with methodological individualism), but rather on the study of social facts. Inspirations During his university studies at the ENS, Durkheim was influenced by two neo-Kantian scholars: Charles Bernard Renouvier and Émile Boutroux. The principles Durkheim absorbed from them included rationalism, scientific study of morality, anti-utilitarianism, and secular education. His methodology was influenced by Numa Denis Fustel de Coulanges, a supporter of the scientific method. Comte A fundamental influence on Durkheim's thought was the sociological positivism of Auguste Comte, who effectively sought to extend and apply the scientific method found in the natural sciences to the social sciences. According to Comte, a true social science should stress empirical facts, as well as induce general scientific laws from the relationship among these facts. There were many points on which Durkheim agreed with the positivist thesis: First, he accepted that the study of society was to be founded on an examination of facts. Second, like Comte, he acknowledged that the only valid guide to objective knowledge was the scientific method. Third, he agreed with Comte that the social sciences
