“It is the tragedy of the world that no one knows what he doesn't know — and that the less a man knows, the more certain he is that he knows everything.”
What this quote means
This quote by A. J. Cronin highlights a paradox of knowledge: the more we know, the more we realize how much we don't know; the less we know, the more we think we know everything. It denounces the tragedy of ignorance that mistakes itself for wisdom. It resonates in debates where unfounded certainties are expressed with confidence, inviting us to cultivate intellectual humility and acknowledge the limits of our understanding.
