This text explores the historical evolution of philosophical inquiry, beginning with the early focus on physis (nature) and the subsequent shift toward human and social concerns initiated by the Sophists and Socrates. The author highlights that ancient Greek philosophy lacked the modern conception of the subject as an "I," a notion that fully emerged through German Romanticism. This concept of subjectivity is traced back to the Protestant emphasis on individual conscience and non-transferable responsibility before God. The roots of this perspective are identified not in the Greek tradition, but in the prophetic legacy of ancient Israel and the teachings of Jesus. While Greek thought is characterized by objectivism, Christianity historically had to navigate the tension between these Greek frameworks and the biblical emphasis on the uniqueness of the human person. The document thus provides a concise overview of the shifting focus of philosophy from the external world to human interiority and the theological foundations of modern subjectivism.
