This ancient Greek aphorism, famously attributed to Socrates through Plato's dialogues, represents one of philosophy's most fundamental principles. The maxim emphasizes the importance of self-examination and introspection as the foundation of wisdom. Socrates believed that understanding oneself was essential for ethical behavior and meaningful life. This principle became central to Western philosophy and psychology, influencing approaches to personal development and mental health through the ages. The quote continues to remind us that self-awareness is the starting point for all genuine personal growth and ethical behavior.
