I don&#x27;t know what Feynman was talking about, when he said that. Much philosophy of science is bullshit, in my considered opinion. But Kuhn&#x27;s and Popper&#x27;s work, for example, are not. And I&#x27;d be very surprised if Feynman claimed that they were.<p>Also, maybe Feynman was just fucking with the interviewer. He was like a physics version of Lenny Bruce. But warmer, like Bill Clinton.
