Speaking for Haecceitists

Haecceitism is the thesis that some truths are not necessitated by the qualitative truths. In this paper I explore a general argument that purports to establish that haecceitism leads to objectionably 'cheap' violations of determinism. In response to this argument, I develop a novel position that combines considerations from metaphysics and the philosophy of language to secure the compatibility of haecceitism and determinism. This position has important parallels to the way haecceitism has been developed within counterpart theory, but, crucially, it makes no use of counterpart theory itself.
