Durkheim's social theory examines how society influences individual behavior and actions. He argues that societies are made up of both idealism (values, beliefs, norms) and materialism (division of labor, technology). These factors combine to form social solidarity, which determines the level of social regulation and integration that individuals experience. Too much or too little regulation and integration can lead to different types of suicide - fatalistic (over-regulation), anomic (lack of regulation), egoistic (lack of integration), or altruistic (over-integration). Durkheim believed suicide was driven by imbalances in social forces rather than individual pathology, and that understanding these social influences was crucial to explaining suicide rates.
