Ever science the beginning of sociology, sociologists have shown a great concern in man and the dynamic of society. The emphasis has been oscillating between man and society. "Sometimes the emphasis was on man in society, at other times, it was on man in society. But at no stage of its development, man as an individual was its focus of attention. On the contrary, sociology concentrated heavily on society and its major units and their dynamics. It has been striving to analyse the dynamics of the society in terms of organised patterns of social relations. It may be said that sociology seeks to find explanations for three basic questions: How and and why societies emerge? How and why societies persist? How and why societies change?
An all-embracive and expanding science like sociology is growing at a fast rate no doubt. It is quite natural that sociologists have developed different approaches from the time to time in their attempts to enrich its study. Still it is possible to identify some which constitute the subject matter of sociology on which there is little disagreement among the sociologists. Such topics and areas broadly constitute the field of sociology. A general outline of the fields of sociology on which there is considerable agreement among sociologists could be given here.
Finally, in the present era of explosion of knowledge sociologists have ventured to make specialisations also.Thus, today good number of specialised fields of inquiry are emerging out. Sociology of knowledge, sociology of history, sociology of literature, sociology of culture, sociology of religion, sociology of family etc., represent such specialised fields., The field of sociological inquiry is so vast that any student of sociology equipped with genius and rich sociological imagination can add new dimensions to the discipline of sociology as a whole.
