According to the received tradition, the language used to refer to natural kinds in scientific discourse remains stable even as theories about these kinds are refined.

According to the received tradition, the language used to refer to natural kinds in scientific discourse remains stable even as theories about these kinds are refined. Hence, scientists discover, rather than stipulate, that sentences like 'Whales are mammals, not fish' are true. In this illuminating book, Joseph LaPorte argues that scientists do not discover that sentences about natural kinds, like 'Whales are mammals, not fish', are true rather than false. Instead, scientists find that these sentences were vague in the language of earlier speakers, and they refine the meanings of the relevant natural-kind terms to make the sentences true. Hence, scientists change the meanings of these terms. This conclusion prompts LaPorte to examine the consequences of this change in meaning for the issue of incommensurability and for the progress of science.

Table of contents:
Introduction; 1. What is a natural kind, and do biological taxa qualify?; 2. Natural kinds, rigidity, and essence; 3. Biological kind term reference and the discovery of essence; 4. Chemical kind term reference and the discovery of essence; 5. Linguistic change and incommensurability; 6. Meaning change, theory change and analyticity.

Joseph LaPorte argues that scientists have found that sentences about natural kinds 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.

A study of natural kinds terms and how their meaning has changed over time.
