“…Philosophical understandings of the concept of natural kinds and debates about the usefulness of the very concept for understanding scientific classification and conceptual change are still evolving as philosophers of science expand the focus of their inquiry to a number of diverse and interdisciplinary areas of science (see e.g., Bolker, 2013;Brigandt, 2003Brigandt, , 2010Brigandt, , 2012Bursten, 2016;Godman, 2013;Kendig, 2016aKendig, , 2016bLudwig, 2017;Ludwig, 2018;Muszynski & Malaterre, 2020;Ruphy, 2010;Slater, 2015;Slater, 2013;Tabb, 2019;Tsou, 2013;Zachar, 2000). Natural kinds realists have expressed optimism that just so long as the aims of classification in a given scientific domain are broadly epistemic, natural kinds in some form (e.g., HPC, MPC) will be in the offing (e.g., Boyd, 2019;Kendler et al, 2011;Khalidi, 2013), and there may be different epistemically admirable ways of conceptually carving up the world that cross-cut each other (e.g., Khalidi, 2013).…”
