is an ancient Greek aphorism inscribed on the Temple of Apollo at Delphi.
While famously adopted by Socrates to emphasize that "the unexamined life is not worth living," its origin is debated, often attributed to the Seven Sages of Greece, including Thales or Chilon.
• Meaning: It historically urged individuals to know their limitations and place in the world, often coupled with "Nothing in Excess" (meden agan).
• Socratic Context: Socrates used it to encourage self-examination, believing true wisdom lies in understanding one’s own ignorance and inner self rather than merely focusing on external world knowledge.
• Attribution: Although synonymous with Socrates, the phrase was also linked to Pythagoras and Heraclitus.
• Goal: It represents the foundation of self-knowledge and character development, deemed crucial for a virtuous and fulfilling life. The maxim remains a fundamental call for introspection, challenging individuals to understand their own motivations and, in the words of Aristotle, that "knowing yourself is the beginning of all wisdom"
