 Chakravarrty (forthcoming) argues that natural kind realism has run its course and that attempts to be more liberal about multifarious natural kinds have meant that more recent natural kind realist accounts dissolve into conventionalism. Alternatively, many more recent realist account of natural kinds attempt to cling on to natural kind realism by buttressing it to other forms of realism. For exmaple, theorist have identified what is (mind-independently) real with other things (property clusters, correlations, mechanisms, structures and so on). According to Chakravarrty this is to conflate sui generis natural kind realism with other kinds of realism (e.g. realism about property clusters or realism about mechanisms).
