Socrates' call to examine your life, beliefs, and assumptions
Know thyself (Greek: gnothi seauton) is one of the most famous maxims in Western philosophy, inscribed at the Temple of Apollo at Delphi and made central to philosophy by Socrates. For Socrates, self-knowledge was not about personality tests or preferences — it was about examining your beliefs, questioning your assumptions, and understanding what you truly value. His famous declaration 'the unexamined life is not worth living' established self-examination as the foundation of philosophical practice.

FAQ
What does 'know thyself' mean in philosophy?
In philosophy, 'know thyself' means examining your own beliefs, values, assumptions, and motivations with honesty. Socrates made this the foundation of philosophical practice, arguing that self-knowledge is the starting point for wisdom. It is not about personality traits but about understanding what you truly believe and whether those beliefs hold up to scrutiny.
Why did Socrates say the unexamined life is not worth living?
Socrates believed that living without questioning your beliefs and values means living on autopilot — following habits, conventions, and assumptions without ever asking if they are true or good. For Socrates, a meaningful life requires regularly examining what you think, why you think it, and whether your actions align with your values.
How do you practice self-examination?
Practice self-examination by regularly asking yourself honest questions: What do I believe and why? What assumptions am I making? What would I do differently if I weren't afraid? The Socratic method of questioning can be turned inward. The Roots app offers guided lessons on Socratic self-examination.
