Sociology is the study of human social life. Sociology has many sub-sections of study, ranging from the analysis of conversations to the development of theories to try to understand how the entire world works. This chapter will introduce you to sociology and explain why it is important and how it can change your perspective of the world around you, and give a brief history of the discipline.

Sociology is a branch of the social sciences that uses systematic methods of empirical investigation and critical analysis to develop and refine a body of knowledge about human social structure and activity. Sometimes the goal of sociology is to apply such knowledge to the pursuit of government policies designed to benefit the general social welfare. Its subject matter ranges from the micro level to the macro level. Microsociology involves the study of people in face-to-face interactions. Macrosociology involves the study of widespread social processes. Sociology is a broad discipline in terms of both methodology and subject matter. The traditional focuses of sociology have included social relations, social stratification, social interaction, culture, and deviance, and the approaches of sociology have included both qualitative and quantitative research techniques.
