"A monomaniac is a sick person whose mentality is perfectly healthy in all respects but one; he has a single flaw, clearly localized. At times, for example, he has an unreasonable and absurd desire to drink or steal or use abusive language; but all his other acts and all his other thoughts are strictly correct."
Emile Durkheim was a French sociologist widely regarded as a founding figure in modern sociology. He established key concepts in social theory and wrote influential works including The Division of Labor in Society and Suicide. His methods shaped the academic study of social facts and institutions.
