Sociology is the scientific study of society, including patterns of social relationships, social interaction, and culture. It is a social science that uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order, acceptance, and change or social evolution. Many sociologists aim to conduct research that may be applied directly to social policy and welfare, while others focus primarily on refining the theoretical understanding of social processes. Subject matter ranges from the micro-sociology level of individual agency and interaction to the macro level of systems and the social structure.
Whether sociology can ever become a full-fledged "science" (a description of a class of events predictable on the basis of deductions from a constant ra~onale) depends on whether the terms which sociologists employ to describe events can be analyzed into quantifiable observables.
