Haven't read it yet but ... it does appear Kane was determined to get in a final word about the free-will controversy: https://ndpr.nd.edu/reviews/the-complex-tapestry-of-free-will-a-free-will-odyssey/ For years I've cited his 1990s work as a fine expression of the view with which I associate myself. Kane works from generally secular premises, and reaches a free-willist position that is indeterminist and incompatibilist, the old in-in combo, thereby establishing that certain Jamesian contentions remain in the running. Daniel Dennett (a determinist and compatibilist) replied to Kane and Kane was said to be working on a reply to THAT. Now Dennett and Kane have both shuffled off this mortal coil and this posthumous publication may be the last word in THAT exchange -- if it does contain the response to Dennett I had heard about -- although surely the broader philosophical argument will continue. I'm going to have to get this book.
