Born December 13, 1902 in Colorado Springs. He died at the age of 76 on May 6, 1979 in Munich, West Germany. His field was sociology and he studied at Harvard University. Talcott Parsons studied philosophy, sociology and biology at Amherst College. In 1924 he received his B.A. Parsons also studied at the London School of Economics and received his doctorate from the University of Heidelberg. From 1927 to 1973, he was on the faculty of Harvard University. Parsons developed a theory for the study of society, which he called this theory, theory of action. Action theory was founded in order to identify itself as an attempt to maintain the scientific rigor of positivism. This theory attempted to establish a balance between two major mythological traditions. Parsons was responsible for highlighting the work of Emile Durkheim, Vifredo Pareto and Max Weber. Parsons said it needed to be analyzed in different terms1. Distinction between the structural and the functional.2. Fundamentally distinct difference between maintaining systems balance and structural change. Parsons' studies included that of roles. Roles in society and in families. He even affirmed that the role of the patient is a social role. He found that kinship structures are also clearly subject to significant processes of functional differentiation and have often become the center of political and economic activities. He outlined what became the accepted functional view of education. It argues that primary socialization within the family is taken care of by the school as the focal socialization agency.Charles DarwinBorn on 12 February 1809 in the United Kingdom.He died aged 76 in April 1882 in Kent, United Kingdom.Darwin studied at Cambridge University....... middle of paper ......s. It is a way to help many people deal with their problems and emotions. His method was used to understand what patients felt, what they experienced. Freud's methods changed the world and helped many people. This gave us the opportunity to observe the human brain and how to deal with people who were in an emotional state. Aside from Parsons' research into sociology and how people should act in society, or Darwin's research into how humans have changed over time. Freud's theory talked about how the human brain works, he formulated an understandable theory, he explained his theory correctly and he showed us the different parts of the brain, the unconscious and the conscious, and how it was divided into three: the ego, the id and the superego. This is why I think that Freud's research is the one that allows us to better understand the three concepts.
