Aging & Wisdom Quote by Albert Einstein

Einstein tosses a grenade into the polite fiction that "common sense" is neutral, natural, and earned. By calling it a "collection of prejudices", he reframes the everyday gut feeling as something assembled, not discovered: a grab bag of inherited assumptions, classroom simplifications, family narratives, cultural stereotypes, and survival heuristics that harden into reflex. The sting is deliberate. "Common sense" is usually the last refuge of people who want to stop thinking; Einstein turns it into evidence that thinking has stopped too early.

The line works because it attacks authority while sounding almost conversational. "Collection" is clinical, like he is inventorying mental clutter. "Acquired" implies passivity: you pick these ideas up the way you catch an accent. Then he lands the most provocative detail: age eighteen. Not because adulthood begins there, but because that is roughly when institutions finish their first major draft of you. By then, you have internalized what "obvious" looks like in your society. After that, prejudice can masquerade as wisdom simply because it has been rehearsed longer.

Context matters: Einstein's breakthroughs depended on distrusting the "obvious" rules of space and time that Newtonian physics had made feel like common sense. His jab isn't anti-experience; it's anti-complacency. He is warning that the mind's default settings are not reality-checkers but reality-filters, and that scientific imagination begins where social and cognitive convenience ends.
