Throughout history, sociology has played an important role in understanding social problems that have developed and re-emerged in various societies across the world. Therefore, sociology is considered to be the study of human social behavior and its development of structures and functions in a society. As a result of this study, several sociological theories have developed to explain social phenomena and help to better explain social interaction and human existence. Social theories can be seen as puzzle pieces because they allow us to gather empirical data and interpret the facts necessary to understand what is happening in our worldly societies. This also explains why social theories are often very abstract since they are used. Social theory allows sociologists to question all aspects of society and develop theories about why certain human behaviors occur. Therefore, studying social theory helps explain these theories and allows people to understand their importance. A good example of this understanding would be Emile Durkheim's theory of the division of labor in society. This theory provides insight into how modern society is not united by the similarities of individuals but rather by the division of labor. According to the textbook Sociological Theory, "it is the division of labor itself that brings people together by forcing them to depend on each other, and the economic services it can render are insignificant compared to the moral effect it it produces and its true function is to create between two or more people a feeling of solidarity” (Ritzer & Siepnisky, 2011, p. 85). From this example, it is clear that it is important to study social theory in order to understand how society might function when it comes to work. Without its study, as well as other theories, then people would be lost trying to interpret and understand society. When considering the theories that sociology presents to us, it is important to keep an open mind and allow ourselves to question and reflect on our own lives and ideas regarding society. Therefore, making assumptions is an essential reason why we should study social theory, as it also allows us to question existing ideas formulated by sociologists, such as Marx, Durkheim or Weber. For example, Karl Marx has long been questioned about his work with capitalism and his most famous work, The Communist Manifesto. Marx is an emblematic sociologist for the symbolism associated with his name; However, many of the points in his work allow us to keep an open mind and wonder how his work relates to today's society or how his predictions are disproven or true. By questioning these existing ideas and theories, we can then challenge our own thinking and find justifications for supporting or abandoning these ideas and theories.
