in anyone's lives. Altruistic suicide corresponds to too much social integration. This occurs when a group dominates the life of an individual to a degree where they feel meaningless to society. Anomic suicide occurs when one has an insufficient amount of social regulation. This stems from the sociological term anomie, meaning a sense of aimlessness or despair that arises from the inability to reasonably expect life to be predictable. Fatalistic suicide results from too much social regulation. An example of this would be when one follows the same routine day after day. This leads to a belief that there is nothing good to look forward to. Durkheim suggested this was the most popular form of suicide for prisoners. This study has been extensively discussed by later scholars and several major criticisms have emerged. First, Durkheim took most of his data from earlier researchers, notably Adolph Wagner and Henry Morselli, who were much more careful in generalizing from their own data. Second, later researchers found that the Protestant–Catholic differences in suicide seemed to be limited to German-speaking Europe and thus may have always been the spurious reflection of other factors. Durkheim's study of suicide has been criticized as an example of the logical error termed the ecological fallacy. However, diverging views have contested whether Durkheim's work really contained an ecological fallacy. More recent authors such as Berk (2006) have also questioned the micro–macro relations underlying Durkheim's work. Some, such as Inkeles (1959), Johnson (1965), and Gibbs (1968), have claimed that Durkheim's only intent was to explain suicide sociologically within a holistic perspective, emphasizing that "he intended his theory to explain variation among social environments in the incidence of suicide, not the suicides of particular individuals." Despite its limitations, Durkheim's work on suicide has influenced proponents of control theory, and is often mentioned as a classic sociological study. The book pioneered modern social research and served to distinguish social science from psychology and political philosophy. Religion In The Elementary Forms of the Religious Life (1912), Durkheim's first purpose was to identify the social origin and function of religion as he felt that religion was a source of camaraderie and solidarity. His second purpose was to identify links between certain religions in different cultures, finding a common denominator. He wanted to understand the empirical, social aspect of religion that is common to all religions and goes beyond the concepts of spirituality and God.
