Linguistic Justice

The world is full of situations of asymmetric bilingualism: the members of one linguistic group learn the language of another without the latter reciprocating. In such a situation, the cost of learning is borne by one group, whereas the benefit is enjoyed by both. This paper first argues that, in the absence of any cost-sharing device, such situations are unjust. Next, it critically examines four potential criteria of linguistic justice, each of which offers a distinct answer to the question of how to allocate between two linguistic groups the cost of one of them learning a second language. Criteria suggested by Church and King, Jonathan Pool and David Gauthier are spelled out and rejected in favour of a criterion of equal ratios of benefit to cost. Lastly, the paper sketches some policy implications concerning what is owed by English natives to the rest of mankind as a result of English being adopted as a worldwide lingua franca.
