Protecting Vulnerable Languages

This chapter explores an important but understudied argument in favor of protections for vulnerable languages. The argument observes that speakers of such languages can face a collective action problem. The question is what interventions by the state to correct such a problem would be consistent with, or even required by, a broadly liberal and egalitarian conception of justice. The chapter identifies two principles that are relevant to answering this question: the unanimity principle, which places strict limits on interventions, and the principle of correction, which licenses a more extensive range of interventions on behalf of vulnerable languages. The principles are in tension with one another but derive from a common source in liberal egalitarian thought. Overall, the right approach is to forge a compromise between the two principles, thus allowing for some interventions on behalf of vulnerable languages to protect against collective action problems.
