This text examines the transformations of philosophical thought from ancient Greece to the modern shift toward subjectivity. The author focuses on the central question of Greek thinkers: what remains constant amidst changes, and from what does everything originate? Greek philosophy is defined here as an essential practice of questioning, situated between absolute knowledge and total ignorance. The original attempt to base understanding on an objectively given principle, or ARCHÉ, eventually reached its limits over the centuries. The text describes a fundamental historical turning point when the focus of philosophical inquiry shifted from the pursuit of objective truth—understood as correspondence with reality—to the pursuit of subjective certainty and evidence. This process, while not sudden, represents a crucial transformation in the understanding of the world and human knowledge. The reflection emphasizes that the world cannot be fully understood solely through a fixed, objectively given foundation, which led to a gradual reassessment of traditional metaphysical premises.
