Functionalism is a sociological perspective that focuses on the ways in which a complex pattern of social structures and arrangements contributes to social order. It was designed to perform the essential functions of human life. A shortcoming of the functionalist perspective is that we have rarely seen anything approaching equilibrium in human society. Ultimately, change is seen as a dysfunction within this school of thought. Two prominent theorists within the functionalist school of thought were Emile Durkheim and Talcott Parsons. Emile Durkheim was the founder of sociology in France. His best-known books are "The Division of Labor in Society", "Rules of the Sociological Method" and "Suicide". Durkheim was the first university professor with a chair in the Social Sciences department and also founded the first scientific sociology journal called “L'année Sociologique”. Durkheim developed a model of society that evolves from simple solidarity to complex solidarity. According to Durkheim, simple societies have no division of labor. Furthermore, there is no variation in individuality, so these societies are more unstable and prove to be affected by change. Complex societies, on the contrary, lead to specialization of work, individuality and interdependence. In an article by Durkheim entitled "The Dualism of Human Nature and Its Social Conditions" Durkheim describes two types of tendencies within each individual. These tendencies are sensations and sensory tendencies, conceptual thinking, and moral activity. Durkheim explains sensation and sensory tendencies, conceptual thought and moral activity as two poles that very often oppose each other. Sensations and sensory tendencies are described as "affecting our individuals...... middle of paper...... ills, C. Wright (1916 - 1962)." The Blackwell Dictionary of Sociology.
