Irreplaceable truth

Conceptual engineers are always on the lookout for concepts that can be improved upon or replaced. Kevin Scharp has argued that the concept truth is inconsistent, and that this inconsistency thwarts its ability to serve in philosophical and scientific explanatory projects, such as developing linguistic theories of meaning. In this paper I present Scharp’s view about what makes a concept inconsistent, and why he believes that truth in particular is inconsistent. Then I examine the concepts that he suggests should replace truth for various explanatory and expressive duties. I argue that those concepts are not up to the tasks for which they are posited, and so Scharp’s replacement methodology itself needs to be reengineered.
