Steven Pinker's new book, "Rationality", was just released. My impression, 1/4 through, is that it could use a strong dose of "meta-/post-rat" (whatever that means)!

It fails to grapple with the very real problems of reductivism, endemic to most systematic frameworks and especially this one. Whether we characterize something as a vegetable, in practice, is highly contingent; systematizations of that decision rule are mostly unhelpful.
