David Macarthur (University of Sydney) reviews the book for NDPR. Here's the link.
Like me, Macarthur holds to a "liberal" conception of naturalism. The following passage from MacArthur's review captures my sentiments about more conservative forms of naturalism:
"Ritchie's strategy of taking up a position within the landscape of current scientific naturalism, however, leads to a blindspot about the range of viable naturalisms on offer in contemporary philosophy. He misses the possibility of a non-scientific or liberal naturalism that is arguably associated with such leading philosophers as Dewey, McDowell, Putnam and Wittgenstein. Such naturalism lies in the largely unexplored conceptual space between scientific naturalism and supernaturalism. It allows that one can respect science without supposing that science is our only resource for understanding humanity. Not everything that exists is explicable, or fully explicable, by science. There are many things in our everyday world of which there is no complete scientific theory but that are, nonetheless, presupposed by science -- e.g. tables, persons, artworks, institutions, rational norms. A liberal naturalism can more readily do justice to such things. It is also in a better position to ask whether there exist non-scientific modes of knowing and understanding tables, persons, reasons, etc. The best prospects for an account of rational or conceptual normativity ("the hardest task") are, presumably, neither scientific nor supernatural."
