He saw similar properties between society and the human body. He also asserted that just as various bodily systems work together to maintain the functioning of the body, society has different structures that work together to maintain the functioning of society (Spencer 1898). Emile Durkheim is another sociologist who used Herbert Spencer's theory to explain change in society. He believed that society is a very complex system of interrelated and interdependent parts that work together to maintain stability (Durkheim 1893). This ensures that the social world is held together by shared values ​​and languages. He wrote the Division of Labor. Robert Merton, sociologist of functionalism, each interdependent structure has a manifest or latent function. Manifest functions are functions that are intended and have obvious consequences. That being said, manifest functions are specifically understood by people. They are deliberate and conscious. Latent functions are involuntary and the consequences are not as clear. These types of functions are not openly stated, predicted or intended by those involved. These two functions go hand in hand in sociology because one does not go without the other.
