Theoricity and homology: a reply to Roffe, Ginnobili, and Blanco.

Roffe et al. (Hist Philos Life Sci, 2108. https://doi.org/10.1007/s40656-018-0208-z ) develop a rather creative line of response to Pearson's (Hist Philos Life Sci 32(4):475-492, 2010) critique of pattern cladisma response centering on a structuralist approach to the homology concept. In this brief reply I attempt to demonstrate, however, that Roffe, and Ginnobili, and Blanco subtly mis-characterize the target of Pearson's critique. The consequence of this mischaracterization is that even though the structuralist framework may help make sense of pattern cladism, it does not undermine Pearson's critique of it.
