An "unmoved mover" is a philosophical concept that refers to a force or entity that initiates action without being influenced by any external factors. This concept has been described by many different terms throughout history, including "prime mover," "first cause," and "uncaused cause." In modern philosophy, the concept is often associated with the teachings of Aristotle and the ancient Greek philosophers. Other synonyms for "unmoved mover" include "eternal being," "self-sufficient cause," and "absolute reality." While the term has its roots in religious and philosophical discourse, it has since been adopted by scholars in various fields, including physics and neuroscience, to describe the fundamental causes of the universe and human behavior.
