Mixing quantitative and qualitative methods, Durkheim provides the basis for the future development of sociology. He brings science to the study of society, by developing a hypothesis, gathering data and testing the hypothesis. He proves the powerful influence of society on the behavior of individuals, which, though obvious today, was not a clear conclusion at the time.
This is a basic reading for anyone interested in sociology. However, anyone interested in the application of scientific methods to society and other non-traditional fields for science would also find it very useful.
