Indexicals and Sider’s Neo-linguistic Account of Necessity

Sider offers a new take on a linguistic account of necessity. In this paper, I assess his view’s vulnerability to objections made against more traditional linguistic accounts, especially an argument I call the “indexical problem.” I conclude that the indexical problem has no force against Sider’s approach because the view is able to attribute modal properties directly to propositions, rather than indirectly via analytic sentences that express them. However, Sider also argues that traditional linguistic accounts fail because of two well-known problems, and I argue that the same two problems undermine his own account.
