In a recent article, David Ludwig proposed to reorient the debate on natural kinds away from inquiring into the naturalness of kinds and toward elucidating the materiality of kinds. This article responds to Ludwig’s critique of a recently proposed account of kinds and classification, the Grounded Functionality Account, against which Ludwig offsets his own account, and criticizes Ludwig’s proposal to shift focus from naturalness to materiality in the philosophy of kinds and classification.

民族生物学种类和物质基础：对路德维希的评论

在最近的一篇文章中，大卫·路德维希（David Ludwig）提议重新调整关于自然类的辩论，从探究类的自然性转向阐明类的物质性。本文回应了路德维希对最近提出的类型和分类的解释“扎根功能性解释”的批评，路德维希抵消了他自己的解释，并批评了路德维希在类型和分类哲学中将焦点从自然性转向物质性的提议。
