Natural Kinds and Conceptual Change

In this illuminating book, Joseph LaPorte argues that scientists have not discovered that sentences about natural kinds are true rather than false. Instead, scientists have found that these sentences were vague in the language of earlier speakers and they have refined the meanings of these terms to make the sentences true. In the process, however, they have also changed the meaning of these terms. This book will appeal to students and professionals in the philosophy of science, the philosophy of biology and the philosophy of language.
