- Emile Durkheim was a major founder of modern sociology who made several important contributions, including distinguishing sociology from other social sciences and emphasizing empirical data.
- Durkheim argued that sociology should study "social facts" - patterns of behaviors that exert external influence on individuals through norms, mores, and folkways.
- He believed humans have a dual nature, with individual desires that can lead to "anomie" if not regulated by society's collective conscience of shared values and moral rules. Rapid social change and division of labor weaken this collective conscience.
