It may be that all that matters for the modalities, possibility and necessity, is the object named by the proper name, not which proper name names it. An influential defender of this view is Saul Kripke. Kripke’s defense is criticized in the paper.

Saul Kripke’s (1971, 1972) modal essentialist argument against materialism remains an obstacle to any prospective Identity Theorist. This paper is an attempt to make room for an Identity Theory without dismissing Kripke’s analytic tools or essentialist intuitions. I propose an explanatory model that can make room for the Identity Theory within the constraints of Kripke’s view; the model is based on ideas from Alan Sidelle’s, “Identity and Identity-like” (1992). My model explains the apparent contingency of some scientific identities by appealing to our epistemic access to the conditions of identity for sensations and brain processes. Pace Kripke, the Identity Theorist can thus explain away the apparent contingency of mind-brain identity claims.

This paper analyses and criticizes S. Kripke's celebrated argument against materialist identity?theories. While criticisms of Kripke in the literature attack one or more of his premisses, an attempt is made here to show that Kripke's conclusion is unjustified even if his premisses are accepted. Kripke's premisses have sufficient independent plausibility to make this strategy interesting. Having stated Kripke's argument, it is pointed out that Kripke must assume that the contents of the Cartesian intuitions are clear and of a kind suited for the type of explanation he favours, while his own result concerning contents in epistemic contexts is precisely that this might not be so when objects or events we thought distinct happen to be identical. The point is that only by assuming that the identity?theory is false, can Kripke maintain that the Cartesian intuitions express contents which can be explained in his favoured way. But such an assumption is clearly illegitimate when the aim is to establish that the identity?theory is false. Kripke cannot conclude that the identity?theory is false because no explanation of epistemic possibilities is produced, since by his own standards no such explanation can be produced if the identity?theory is true.
