The three theories of sociology are symbolic interaction theory, conflict theory and functionalist theory. Sociologists analyze social phenomena at different levels and from different perspectives.
Symbolic interaction theory is a major framework of sociological theory. This theory relies on the symbolic meaning that people develop and rely upon through the process of social interaction.
Conflict theory emphasizes the role of coercion and power in producing social order. This theory was derived from the works of Karl Marx.
Functionalist theory interprets each part of society in terms of how it contributes to the stability of the whole society. In this theory, the different parts of the society depend on each other.
