Functionalism begins by emphasizing the social sciences and tracing their coordinates among a myriad of theories, ranging from classical to modern.
To this end, Nicklas Nickel has advocated for this approach since the inception of sociology as a scientific discipline. He introduces us to the type of ontology, epistemology, and methodology through the perspectives of Kent, Spencer, and the apex, Durkheim.
Moreover, what was engrafted with "Functionalism" is further explored in the 20th century under the umbrella of "Structural Functionalism". By examining the branches and evolutionary trends of this approach, he enumerates his latest achievements in social explanations in the eyes of neo-functionalists.
Nickel also pinpointed the most important theories and thinkers active in this field in order for us to get more acquainted with the path taken by functionalism in the philosophy of mind and psychology.
Academic currents in both philosophy of mind and social sciences, particularly in the United States, have embraced functionalism at times. It would sometimes deform or even be abandoned as it progressed.
What matters is the legacy of functionalism in the humanities, whose ramifications can still be seen today in opposing and divergent perspectives.
