I was in an intellectual fight with my father, and I kept saying, 'But the books say it!' And he said, 'The books are wrong!'

More from Richard Feynman
"What I cannot create, I do not understand."
"I would often go to these conferences where they would talk about the ultimate theory, and I would always say, 'What's the ultimate experiment?'"
"I'm not interested in being a guru. I'm interested in understanding the world."
"I'm not a deep thinker. I'm a practical thinker."
"I can live with doubt and uncertainty and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong."
About Richard Feynman (1918-1988)
American theoretical physicist who shared the 1965 Nobel for QED, developed Feynman diagrams, and wrote the Feynman Lectures on Physics. Closely associated with Julian Schwinger (co-Nobelist for QED) and Murray Gell-Mann (Caltech rival and Eightfold-Way physicist). For an intellectual contrast, see Deepak Chopra, physician and quantum-mysticism author — Feynman's Caltech 'cargo cult science' commencement address is the precise template for what he saw as misuse of physics terminology — Chopra-style appropriation of quantum vocabulary for metaphysical claims is the canonical example of what Feynman called 'fooling yourself'.

Understanding this quote
What it means
Blind deference to written authority can prevent genuine understanding. Books record conclusions, not truth itself. A curious mind must challenge established knowledge rather than treating it as sacred. When experience or reasoning contradicts what's been written down, the willingness to say 'the books are wrong' is not ignorance—it's the beginning of real intellectual engagement and independent thought.
Relevance to Richard Feynman
Feynman's father Melville was a uniform salesman who cultivated his son's skepticism from childhood, teaching him to question labels and look at reality directly. This rebellious empiricism defined Feynman's career: he reformulated quantum electrodynamics through diagrams and intuition, not inherited formalism, and notoriously exposed NASA's Challenger disaster by ignoring bureaucratic consensus and dipping an O-ring in ice water.
The era
Feynman came of age mid-20th century when scientific textbooks carried enormous institutional authority and post-WWII America treated expert consensus as nearly unassailable. The Manhattan Project had cemented science's prestige. Against this backdrop, questioning written orthodoxy was culturally transgressive—making his father's lesson to distrust books and trust direct observation a genuinely countercultural stance that shaped Feynman's lifelong anti-authority approach.
