The answer is "Sociology".
Sociology is the investigation of human social connections and foundations. Sociology's topic is different, extending from crime to religion, from the family to the state, from the divisions of race and social class to the mutual convictions of a culture, and from social stability to radical change in entire social orders. Binding together the investigation of these various subjects of study is Sociology's motivation of seeing how human activity and cognizance both shape and are formed by surroundings and social structures.
