Aging & Wisdom Quote by Sydney J. Harris

"Nobody can be so amusingly arrogant as a young man who has just discovered an old idea and thinks it is his own"

About this Quote

The jab lands because it’s aimed at a very specific kind of confidence: not earned mastery, but the adrenaline rush of “discovery” without historical memory. Harris, a journalist who made a career out of puncturing public pretensions, frames arrogance as “amusing” not to soften it but to underline how transparent it is. The young man isn’t wicked; he’s in a stage-managed delusion, mistaking recognition for invention. That’s the joke and the warning.

The line works by compressing two timelines into one sentence. There’s the long, slow timeline of ideas - recycled, revised, handed down, usually with receipts. Then there’s the instant timeline of ego: the moment you read something old and it clicks, your brain tags it as yours. Harris is diagnosing a cognitive glitch that culture continually rewards. Modern life idolizes novelty, so people learn to perform originality even when they’re mostly rebranding. The quote skewers that performance with the gentlest knife: ridicule.

Its subtext is less “young people are dumb” than “ignorance of lineage breeds swagger.” The arrogance is “amusing” because it’s so avoidable: a little reading, a little humility, and the pose collapses. Coming from a mid-20th-century columnist - an era of mass media, hot takes, and ideological reinventions - it’s also a comment on public discourse. Every generation thinks it’s inventing skepticism, liberation, realism, rebellion. Harris reminds us that the oldest idea of all is believing you’re the first to have one.
