Abstract
The main research methodology of the philosophy of language is conceptual investigation and its main task is to clarify or disambiguate concepts. Undoubtedly, this is a basic consensus in the circles of the philosophy of language. However, with the development of the discipline, people have realized that the research of the philosophy of language should not stop at conceptual clarification or disambiguation, but it should tinker with or replace concepts and when necessary, create new concepts. These are the new developments in the philosophy of language. Central to these developments is the research of conceptual engineering. What exactly is conceptual engineering? What practical values does it have? Centering around these questions, this paper presents an exploration of conceptual engineering itself with a view of revealing its essence and analyzing its practical implications. The basic tasks of conceptual engineering include conceptual design, implementation and evaluation. The practical value of conceptual engineering is that it pushes conceptual clarification or disambiguation toward conceptual construction.
