"The easiest way to fool yourself is to believe something because you want it to be true."
"The thing that I cannot understand is that I can't understand it."
"The thing that doesn't fit is the thing that is most interesting."
"I'm not a deep thinker. I'm a practical thinker."
"I was always interested in things that are on the edge of what we know."
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
Science advances not by confirming what you already believe, but by actively seeking evidence that destroys your own theories. A hypothesis only earns trust after surviving rigorous attempts to break it. This discipline separates genuine knowledge from wishful thinking — you must be your own harshest critic, willing to discard any idea, no matter how elegant, the moment reality contradicts it.
Relevance to Richard Feynman
Feynman built his career on intellectual honesty bordering on ruthlessness. He famously exposed the Challenger disaster by dunking O-ring material in ice water live on television — pure empirical thinking over institutional comfort. His Caltech commencement address defined cargo cult science as the failure to do exactly this: check yourself. Winning the Nobel Prize in QED didn't soften his demand that even prize-winning ideas must remain perpetually vulnerable to disproof.
The era
Feynman worked through the Cold War's science boom, when government funding and prestige created enormous pressure to produce confident, fundable results. Simultaneously, postwar physics had just revolutionized the world with atomic weapons, making the stakes of bad science viscerally obvious. In that climate of institutional authority and ideological certainty, insisting that self-doubt was the engine of progress was a genuinely countercultural stance.
