The concept of "observer" refers to a subject involved in the act of watching, often functioning as a critical lens through which reality is understood. In literature, this role has been examined from multiple angles: Schopenhauer portrays the observer as a detached onlooker, while Heine emphasizes the difficulties of witnessing evolving human interactions.
Chesterfield suggests discreet observation to prevent bias, and Krishnamurti challenges the very distinction between observer and observed. These differing viewpoints highlight the observer's function as both a mediator of reality and an active contributor to its formation, exposing the conflict between objectivity and subjectivity.
