Abstract
Carnapian tolerance is practiced when an issue is viewed as “merely a matter of choosing a language.” This chapter distinguishes between three kinds of cases in which this attitude might show up, and associates these cases with a distinction between three increasingly problematical degrees of tolerance. In the first degree each side has the concepts needed to charitably interpret the other side; in the second degree an expansion of concepts is required; the third degree is verificationism. The chapter defends the first degree, is tentative about the second degree, and is opposed to the third degree.
