Agree totally re: Parfit's two books, and this is a really interesting explanation. A couple of thoughts:

1) In order for crowds to meaningfully exercise their wisdom, there has to be a good mechanism for successfully translating this wisdom into action; markets are such a mechanism, so is voting. Filtering this wisdom through the pen of a single author, especially one in Parfit's position (he knew his work would pass peer review, he saw himself as in a race against time to produce a magnum opus that would surpass R+P) seems like a much worse mechanism. To be frank, I think that in Parfit's case, responding to more superficial, sympathetic, "insider" criticism gave him a kind of "cover" that enabled him to avoid really taking in deep reservations about the work without seeming obviously unduly rigid.

2) I don't know if the wisdom of crowd hypothesis applies when it comes to explanations of the sort that major works of philosophy are, or should be, in the business of offering. Lots of peer input can save you from errors, but it's also a source of disunity, and explanation seems to be about unity -- assimilating the unfamiliar to the familiar.

Two hypotheses, very theoretical. I haven't read On What Matters.

1. Maybe the reason it probably won't make a lasting splash is that it's 1,500 pages? Like, imagine an argument that, somehow, definitively proves controversial and substantive philosophical conclusion, C. However, imagine this argument has 40,000 steps. It's not going to convince anyone, save for ChatGPT.

2. Maybe the reason is that the project is just misconceived? Parfit had this notion that secular ethics had just started, and he seemed to think (didn't he?) that we could actually reach consensus on matters once religion had fully receded. I think that second conviction (I'm not sure he held it, but I think he did) may have motivated his attempt to dot every i, but it probably--hell, I'll say definitely--underestimates the role that sentiment plays in our philosophical conclusions.
