The phenomenon of rigid designation - in particular, de jure rigidity - is typically treated metaphysically. The picture is: reference is gained in a way that puts no constraints on what an object in other worlds, or counterfactual situations must be like, in order to be the referent of that term, other than 'being this thing'. This allows 'pure metaphysical' investigation into, and discovery of 'the nature' of the referent. It is argued that this presupposes a 'privileged' ontology, of a (...) sort that is far from obvious. An alternative picture of rigidity is sketched, terms have associated criteria of identity and criteria of application for counterfactual situations. A term is rigid when these coincide. Aside from being a better account of rigidity, it also undermines the picture of rigid terms allowing us to 'metaphysically' investigate the nature of the referent: matters of identity and essence for the referent are settled by these semantic constraints (though it can be done in a way that allows are a posteriori necessities).

The simple proposal for a characterization of general term rigidity is in terms of sameness of designation in very possible world. Critics like Schwartz (2002) and Soames (2002) have argued that such a proposal would trivialize rigidity for general terms. Martí (2004) claims that the objection rests on the failure to distinguish what is expressed by a general term and the property designated. I argue here against such a response by showing that the trivialization problem reappears even if one pays (...) attention to such a distinction. (shrink)

Is there a theoretically interesting notion that is a natural extension of the concept of rigidity to general terms? Such a notion ought to satisfy two Kripkean conditions. First, it must apply to typical general terms for natural kinds, stuffs, and phenomena, and fail to apply to most other general terms. Second, true 'identification sentences' (such as 'Cats are animals') containing general terms that the notion applies to must be necessary. I explore a natural extension of the notion of rigidity (...) to general terms, the notion of an essentialist predicate. I argue that, under natural assumptions, this notion satisfies the two Kripkean conditions. (shrink)

Th e simple proposal about rigidity for predicates can be stated thus: a predicate is rigid if its canonical nominalization signifi es the same property across the different possible worlds. I have tried elsewhere to defend such a proposal from the trivialization problem, according to which any predicate whatsoever would turn out to be rigid. Benjamin Schnieder (2005) aims fi rst to rebut my argument that some canonical nominalizations can be fl exible, then to provide fi ve arguments to the (...) eff ect that they are all rigid, and fi nally to propose a general explanation of why they are all rigid. I show fi rst why my argument has not been rebutted, then why Schnieder’s fi ve arguments for their rigidity all fail, and fi nally why the alleged “explanation” cannot be such, as the facts alluded to are neutral with respect to the rigidity or fl exibility of the nominalizations.

Linsky’s central point is correct; Kripke’s distinction between rigid and nonrigid designators can be extended in a straightforward way from singular terms to general terms. In both cases, for an expression to rigidly designate its extension is for it to designate the same extension with respect to every possible world-state (in which it has an extension at all). On this account, simple natural kind terms like water, gold, electricity, blue, and tiger – as well as ordinary general terms like bachelor, (...) philosopher, automobile and triangle – designate the same extension with respect to each world-state. As I see it, however, the two differ importantly in the metaphysics of their designata. Whereas a term like bachelor designates a property that may be distinguished from other properties that are necessarily coextensive with it, natural kinds differ from one another only if there are possible world-states in which some of their instances are different. Intuitively this seems plausible; it is hard to imagine two distinct species of animal, two distinct substances, or two distinct colors which have precisely the same instances in every possible world-state. This is important for my linguistic model. Consider, for example, the color blue (which I take to be a natural kind). Color science tells us that the object-color blue is determined.. (shrink)

In this paper I examine two ways of defining the rigidity of general terms. First I discuss the view that rigid general terms express essential properties. I argue that the view is ultimately unsatisfactory, although not on the basis of the standard objections raised against it. I then discuss the characterisation in terms of sameness of designation in every possible world. I defend that view from two objections but I argue that the approach, although basically right, should be interpreted cautiously.

According to Scott Soames’ Beyond Rigidity, there are two important pieces of unfinished business left over from Saul Kripke’s influential Naming and Necessity. Soames reads Kripke’s arguments about names as primarily negative, that is, as proving that names don’t have a meaning expressible by definite descriptions or clusters of them. The famous Kripkean doctrine that names are rigid designators is really only part of the negative case. The thesis that names refer to the same object with respect to every possible (...) world is a byproduct of their meaning, not a positive account of what they mean. As well, the hints about causal chains and dubbings are no more than a picture, as Kripke says, and not a positive theory of meaning. Thus one piece of unfinished business, to which Soames devotes the most attention, is to give a positive account of the meanings of names. To do this Soames proposes that the meaning of a singular term is the contribution it makes to the semantic content of the sentences in which it occurs. The semantic content of a sentence is ordinarily a proposition, that proposition expressed by the most commonly intended assertion using the sentence. Soames’ proposal for a positive account is that the meaning of a proper name is its contribution to those propositions, simply the object to which it refers. Arguing for this positive account occupies the bulk of the book but I will not discuss it in my contribution to this symposium. (shrink)
