The basic insight of sociology is that human behaviour is largely shaped by the groups to which people belong and by the social interaction that takes place within those groups. The main focus of sociology is mainly interested in the interaction between people--- the ways in which people act towards, respond to, and influence one another. Sociology, does not, however, study everything that happens in society or under social conditions. For example, sociologist study religion only insofar as it affects social relationship, i.e., the relationship of man to man, of one group to another, or of one group to the whole society.
