Large-scale book-length treatises on natural kinds are rather few compared to the amount of discussion on the subject and not since Brian Ellis’ Scientific Essentialism perhaps has anyone attempted to build a philosophical “world view” around a theory of natural kinds. Most discussion about natural kinds of the last decade has restricted itself to specific issues, such as the species debate or chemical kinds, or, as in the case of LaPorte (2009), the semantic practices surrounding kind concepts and conceptual change. In this respect, Magnus’ Scientific Enquiry and Natural Kinds: From Planets to Mallards has a worthy ambition, not least for displaying how rich and informative natural kind discussion can be despite its recent characterization as a philosophical dead end (see Hacking 2007).
