A dictionary defines sociology as the systematic study of society and social interaction. The sociologist Dorothy Smith (1926 – ) defines the social as the “ongoing concerting and coordinating of individuals’ activities” (Smith 1999). Sociology is the systematic study of all those aspects of life designated by the adjective “social.” These aspects of social life never simply occur; they are organized processes. They can be the briefest of everyday interactions—moving to the right to let someone pass on a busy sidewalk, for example—or the largest and most enduring interactions—such as the billions of daily exchanges that constitute the circuits of global capitalism. If there are at least two people involved, even in the seclusion of one’s mind, then there is a social interaction that entails the “ongoing concerting and coordinating of activities.” Sociologists study all aspects and levels of society.
