This text explores a critical reflection on the origins of ancient Greek philosophy, specifically focusing on an ontological and epistemological prejudice that has profoundly shaped the entire European intellectual tradition. The author identifies a fundamental error in the conviction that true and reliable knowledge is exclusively tied to the act of immediate seeing or beholding (theoria) within the present moment. This fixation on visual perception and current presence established a terminology that has endured for centuries in various derivatives, although its original meaning and the specific emphasis on temporal immediacy have weakened over time within the broader European context. The article examines the etymological and philosophical development of the term theorein, investigating how this particular link to the present has influenced our collective understanding of truth and knowledge. It suggests that while the term theory has become commonplace in modern language, its inherent connection to present insight remains a hidden yet defining element of philosophical orientation in the world. This necessitates a new critical re-evaluation of our cognitive foundations and the historical continuity of concepts that are often taken for granted today.
