Summary

This quote, often attributed to American physicist Richard Feynman, highlights the importance of self-awareness and intellectual honesty. It suggests that individuals have a tendency to deceive themselves more easily than others. It emphasizes the need to avoid self-deception and acknowledge one's own biases, blind spots, and limitations.
