What, "major point" was that?
It’s amazing that you don’t know.
Here’s the quote, one last time:
FEYNMAN: The first principle is that you must not fool yourself and you are the easiest person to fool.
What do you think Feynman means by that, Rodman?
How might we fool ourselves? And what is he indicating in saying "and you are the easiest person to fool?"
What steps, would this suggest in a method of empirical inquiry? What variables might he be referencing? Are you aware of the long scientific literature on the subject that would bear on this question in terms of how human beings think? And what steps science often takes to minimize that variable?
Feynman wants us to learn from experience....but it is a *specific type of carefully controlled experience.* The type that separates scientifically gained knowledge from, say, dowsing, or astrology, or religion, or new age healing crystals etc.
"Try It For Yourself" does not capture the specific rigor of the scientific method.
I’ve given you all the pieces, I’m sure you can put it together in to answering what Feynman meant (and thus how your previous post had ignored Feynman’s warning).
