Sociology has broad and wide scope. Sociology is very elastically science; it is very difficult to determine just where it ends. V.F. Calberton has his important remarks regarding the scope of sociology. There is a controversy among the sociologists about its area of study. A group of sociologist tried to limit its area where the other groups of sociologist deny it or are against it. There are two schools of thoughts:-
1. Specialistic or Formalistic school of thought
2. Synthetic school of thought
Sociologists of Formalistic school of thought say sociology should study only the form of social relationship. Sociologist of this school of thought says sociology should only study about the society.
