"What a man knows at fifty that he did not know at twenty is for the most part incommunicable"
About this Quote
“Incommunicable” does double work. On one level, it’s an almost tender admission of generational distance: older people can’t simply hand younger people the internal guardrails they’ve built. On another, it’s a sly defense against the modern expectation that leaders should always “explain themselves” into credibility. Stevenson, the cerebral midcentury Democrat, operated in a culture that prized public reason but also punished complexity on the stump. The quote suggests a painful asymmetry: mature judgment is real, yet it won’t fit inside a speech, a memo, or a campaign slogan.
There’s also a democratic bite to it. If the most valuable lessons can’t be transmitted, politics can’t be a technocracy of elders lecturing the crowd. It has to make room for younger citizens to learn the slow way, by living through the consequences. Stevenson isn’t romanticizing ignorance; he’s acknowledging that some truths only become legible after you’ve paid for them.
