"Le Suicide: Etude de Sociologie" by Émile Durkheim is a sociological study published in 1897. This groundbreaking work examines suicide not as an individual act but as a social phenomenon shaped by collective forces. Durkheim identifies four types of suicide based on social integration and moral regulation, revealing how factors like religion, marital status, and economic upheaval influence suicide rates across different societies. His findings challenge conventional understanding by demonstrating that even the most personal decision reflects broader social currents.
