What fundamental idea did Socrates teach?

Socrates is renowned for his emphasis on intellectual humility, which is a recognition of one's own limitations in knowledge and an openness to dialogue and questioning. This concept is often encapsulated in the Socratic method, a form of cooperative argumentative dialogue that encourages individuals to examine their beliefs and the implications of those beliefs critically. Socrates famously claimed that he knew nothing except the fact of his ignorance, highlighting the importance of acknowledging what one does not know as a starting point for genuine inquiry and understanding. This fundamental idea contrasts sharply with attitudes of certainty and blind tradition, underscoring the value he placed on self-examination and the pursuit of wisdom through questioning and discussion. In essence, Socrates teaches that true knowledge begins with recognizing our ignorance and remaining humble in our quest for understanding.
