Originally published in 1949, this third edition of Sociology in 1966 asks the questions: What do sociologists study? What methods do they employ? How far are economic and political patterns, population distribution, the accepted system of social institutions, religious and ethical ideas responsible for the social structure, how far for social diseases such as poverty and crime? The author provides the answers with a clear account of sociology as a discipline at the time. Today it can be read in its historical context.
