Farley, John E. 1998.
Sociology is the scientific study of human group living and the products human relations.
What this means is that sociology is a social science, it uses the scientific method to understand how people live and what arises when people are together and interact with each other. People may ask why we need science to understand people. I have common sense to help me unravel what is going on around me. But each person's common sense is not the same, each of us may look at our social environment differently. What science does is to give us a set of tools that work consistently, no matter who uses them or when they are used.
