I’m also enamored of Feynman so I may look for it.
As far as the Doug’s evaluation of the Russel book goes, it sort of reminds me of my feelings when an acquaintance thought he was doing me a favor by buying a paperback for me on easy ways of approaching the mathematics of chemistry. It would have been great for a first or second year student, but. . . He had no scientific background so didn’t see that it wouldn’t have been of value beyond that level. Similarly, a simplistic book about a philosopher would probably not be highly rated by someone with a PhD in the field.
