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
Labeling something doesn't mean you understand it. Knowing a word — a bird's name, a disease, a concept — gives you nothing about how it actually works, what causes it, or how it behaves. Real knowledge means grasping the underlying mechanism, the why and how, not just possessing a vocabulary term you can recite when asked.
Relevance to Richard Feynman
Feynman's father taught him this lesson as a child, pointing to birds and explaining their behavior rather than just their names. It became central to his teaching philosophy and scientific method. As a Nobel-winning physicist who rebuilt quantum electrodynamics from first principles, Feynman was famous for refusing to accept jargon as understanding — he'd rederive everything himself rather than trust a label.
The era
Post-WWII physics and academia were increasingly specialized and jargon-heavy. The Cold War arms race created pressure to produce technical credentials fast. Feynman stood against credentialism in an era of growing institutional science bureaucracy, where classification systems and terminology could substitute for genuine comprehension. His Caltech lectures in the 1960s deliberately stripped away received wisdom to rebuild understanding from scratch.
