People live in a big group. 

Some thinkers look at society as a big system. They believe all parts work together to keep things steady. This idea is called structural functionalism. 
Herbert Spencer used a special idea to explain this. He said society is like a human body. In a body, organs work to keep you alive. In a society, different parts work to keep the group going. These parts include families and jobs. 
Émile Durkheim also studied how groups stay together. He said old groups stayed close through shared values. He called this mechanical solidarity. Modern groups are different. In these groups, people do many different tasks. They rely on each other to survive. He called this organic solidarity.
Auguste Comte was the first to use the word sociology. He thought society moves through three stages. It moves from religious views to scientific views. Talcott Parsons later wrote about how people act in these systems. He said people follow rules called norms. When people follow these rules, they fill a role. These roles help the whole system work.
Some thinkers look at society as a large, complex system. They believe all the different parts work together to keep things steady. This idea is called structural functionalism. It focuses on the big picture of how society works. This approach looks at social structures that shape everything. It views society as something that evolves like a living thing. 
This idea uses a special way to explain how things work. It uses the biological analogy to describe society. This means comparing a society to a human body. In a body, organs work together to keep you alive. In a society, institutions like families and jobs work the same way. These parts help the whole system function properly. They work in a way that feels almost automatic. This helps the entire social system stay in balance. 
Many important people helped build this theory over time. Auguste Comte was the first to use the word sociology. He believed society moves through three different stages. It starts with religious views and moves toward scientific views. Later, Herbert Spencer became a very important thinker for this idea. He wrote a massive work called Principles of Sociology between 1874 and 1896. He was one of the first to use the body analogy. His ideas helped shape how later thinkers studied the world.
Other thinkers added more details to these big ideas. Émile Durkheim studied how groups stay together over time. He spoke about mechanical solidarity in older, pre-industrial societies. These groups were held together by shared values and morals. He also spoke about organic solidarity in modern, complex societies. In these groups, people do very different and specialized tasks. This makes people rely on each other to survive. 
Later, Talcott Parsons added more to the study of social roles. He began writing about these ideas in the 1930s. Parsons believed the social system is made of individual actions. He said people have expectations of how others will act. These expectations come from shared rules called norms. When people follow these norms, they fill a specific role. One person can even have many different roles at once. 
Structural functionalism is a theoretical framework used in sociology. It views society as a complex system of parts. These parts work together to promote stability and solidarity. This approach uses a macro-level orientation. This means it focuses on large social structures. It looks at how these structures shape society as a whole. Functionalists believe that society evolves much like a living organism. 
To understand this, thinkers use the organic analogy. This compares society to a human body. In a body, organs work together to keep the organism alive. In a society, institutions like families or traditions work similarly. These elements are called social structures. They perform specific social functions to maintain the system. The goal is to see how every custom or practice affects a stable system. This helps the entire social body reach an equilibrium. 
Societies can be categorized by how they stay together. Émile Durkheim identified two main types of social bonds. The first is mechanical solidarity. This is found in pre-industrial societies. These groups are held together by shared moral values and common sentiments. The second type is organic solidarity. This occurs in modern, complex, industrial societies. In these groups, people perform highly specialized tasks. This specialization creates a strong interdependence among members.
History shows how these ideas developed through different thinkers. Auguste Comte is known as the "Father of Positivism." He coined the term sociology. Comte proposed that society moves through three distinct stages. The first is the theological stage, where people see society as God's will. The second is the metaphysical stage, where society is seen as a natural system. The final stage is the positive or scientific stage. This stage uses scientific approaches to describe social phenomena.
Herbert Spencer was a major influence on this field. He was a British philosopher who applied natural selection to society. Between 1874 and 1896, he wrote his massive work, "Principles of Sociology." Spencer argued that societies face selection pressures. These pressures force a society to adapt its internal structure. He identified three functional needs for any society. These are regulatory needs, operative needs, and distributive needs. Societies must control coordination, produce goods, and distribute resources.
As populations grow, societies must differentiate their structures. In early tribal societies, kinship systems handled all needs. As density increased, new organizations emerged to manage labor and resources. This led to more specialized roles, such as kings or administrators. This process helps the society handle increasing complexity. 
Talcott Parsons expanded these ideas in the 1930s. He believed the social system is made of individual actions. He focused on how individuals interact based on expectations. These expectations are derived from social norms. Norms are the accepted rules of a society. When people repeat certain behaviors, they create a social role. A role is a way of participating in social interaction. One person can fulfill many different roles at the same time. 
While useful, structural functionalism has faced significant criticism. Many scholars argue it places too little emphasis on struggle. Critics point out that it may overlook political and monetary conflicts. It can also struggle to explain social change and inequality. Some say it focuses too much on cohesive systems. This leads to a contrast with conflict theories. Conflict theories focus on social problems rather than stability. Despite this, functionalism remains a key way to study social systems.
