Self-reflection.

The forecourt of the Temple of Apollo at Delphi held an inscription that has guided human thought for more than 3,000 years. It read "Know thyself" and stood as the first of three Delphic maxims carved into stone. This command was not merely advice but a foundational directive for ancient Greek philosophy. Protagoras later claimed humans are "the measure of all things," shifting focus to individual perception. Socrates adopted the Delphic adage to challenge his contemporaries on their own definitions of humanity. He offered a tongue-in-cheek definition of people as "featherless bipeds" in Plato's Politicus. Aristotle described humans as the "communal animal" or zoon politikon. He also termed them the "thought bearer animal" or animal rationale. These early classifications established self-reflection as central to what it means to be human.
Medieval Religious Perspectives
St Augustine argued that the Fall corrupted original grace and altered the nature of man. The Catholic Church taught that human existence is essentially good yet marred by sin due to concupiscence. Thirteenth-century Pope Innocent III wrote about the essential misery of earthly existence in On the misery of the human condition. Giannozzo Manetti disputed this view in his treatise On human dignity. Medieval Europe viewed life through a lens where the aim should be a beatific vision after death. Belief in an eternal afterlife of the human ka existed in Egypt from the third-millennium Old Kingdom. Actions were assessed to determine the quality of that future existence. King Solomon bewailed the vanity of all human effort according to rabbinic tradition regarding Ecclesiastes. This religious framework made introspection a necessary tool for spiritual survival rather than personal growth.
