Sociology makes a scientific study of society: Prior to the emergence of sociology the study of society was carried on in an unscientific manner and society had never been the central concern of any science. It is through the study of sociology that the truly scientific study of the society has been possible. Sociology because of its bearing upon many of the problems of the present world has assumed such a great importance that it is considered to be the best approach to all the social sciences.
Sociology studies role of the institutions in the development of the individuals: It is through sociology that scientific study of the great social institutions and the relation of the individual to each is being made. The home and family ,the school and educaton,the church and religion, the state and government ,industry and work ,the community and association, these are institutions through which society functions. Sociology studies these institutions and their role in the development of the individual and suggests suitable measures for restrengthening them with a view to enable them to serve the individual better.
Study of sociology is indispensable for understanding and planning of society: Society is a complex phenomenon with a multitude of intricacies. It is impossible to understand and solve its numerous problems without support of sociology. It is rightly said that we cannot understand and mend society without any knowledge of its mechanism and construction. Without the investigation carried out by sociology no real effective social planning would be possible. It helps us to determine the most efficient means for reaching the goals agreed upon. A certain amount of knowledge about society is necessary before any social policies can be carried out.
