Language as a Global Public Good

Language use is a public good. Those using a common language receive benefits that are non-excludable and non-rival. And as more people speak the same language, the greater these benefits are. Sometimes individuals make a conscious decision to learn a language other than their native language in order to receive these benefits, and thereby incur costs. This paper is an attempt to determine how we should share the costs among all beneficiaries. I argue against Van Parijs’s (Linguistic justice for Europe and for the world, Oxford University Press, Oxford, 2011a) proposal for this, and instead argue that an approach found in the work of Gauthier (Morals by agreement, Oxford University Press, Oxford, 1986) is preferable. A general lesson to be drawn from this paper is that the correct principle for distributing the costs of (global) public goods will depend on whether we think the good in question is required by justice or not. Where Van Parijs went wrong, I claim, was in thinking that a cross-border common language is required by justice. © 2014, Springer Science+Business Media Dordrecht.
