Sommario/riassunto

Making use of our prescientific understanding of things, as well as relevant scientific theories, this book presents original arguments for monism with respect to the concept of a natural kind, for essentialism with respect to the members of a natural kind, and for natural-kinds realism with respect to a few chemical, physical, and biological kinds.
