I'm convinced, finally, that Bayesianism is not enough I finally get the point you’ve been making, for years now, and understand that it really was, for many of us, what you call a ‘rationalism’. It’s still very useful! But it’s only useful when used reasonably and, meta-rationally, it may not be useful, or the most useful form of rationality, for some (or most!) possible circumstances. (I just started this ‘book’ from the begining, ignoring your advice to wait until the later parts of the book have been published. I suspect that, given my extended exposure to your writing, I’ll be okay.) Thanks again for all of this wonderful work!
