On David Lewis's original analysis of causation, c causes e only if c is linked to e by a chain of distinct events such that each event in the chain (counter-factually) depends on the former one. But this requirement precludes the possibility of late pre-emptive causation, of causation by fragile events, and of indeterministic causation. Lewis proposes three different strategies for accommodating these three kinds of cases, but none of these turn out to be satisfactory. I offer a single analysis of causation that resolves these problems in one go but which respects Lewis's initial insights. One distinctive feature of my account is that it accommodates indeterministic causation without resorting to probabilities.

This paper defends a simple, externalist account of knowledge, incorporating familiar conditions mentioned in the literature, and responds to Timothy Williamson’s charge that any such analysis is futile because knowledge is semantically un-analyzable. The response, in short, is that even though such an account may not offer a reductive analysis of knowledge-by way of more basic, non-circular concepts-it still has an explanatory advantage over Williamson’s own position: it explains how belief can fail to be knowledge.

An utterance of a sentence involving an incomplete (definite) description, ‘the F’, where the context—even taking the speaker’s intentions into account—does not determine a unique F, would be unintelligible. But an utterance (in the same context) of the corresponding Russellian paraphrase would not be unintelligible. So I urged in ‘A Strawsonian objection to Russell’s theory of descriptions’ (ANALYSIS 53, 1993, pp. 209-12). I compared an utterance of (1) The table is covered with books. with an utterance of (1)’s Russellian paraphrase..

In his influential paper 'Speaker's Reference and Semantic Reference', Kripke defends Russell's theory of descriptions against the charge that the existence of referential and attributive uses of descriptions reflects a semantic ambiguity. He presents a purely defensive argument to show that Russell's theory is not refuted by the referential usage and a number of methodological considerations which apparently tell in favour of Russell's unitary theory over an ambiguity theory. In this paper, I put forward a case for the ambiguity theory that thwarts Kripke's defensive strategy and argue that it is not undermined by any of his methodological points.

David Lewis’s counterpart-theoretic semantics for quantified modal logic is motivated originally by worries about identifying objects across possible worlds; the counterpart relation is grounded more cautiously on comparative similarity. The possibility of contingent identity is an unsought -- and in some eyes, unwelcome -- consequence of this approach. In this paper I motivate a Kripkean counterpart theory by way of defending the prior, pre-theoretical, coherence of contingent directness. Contingent identity follows for free. The theory is Kripkean in that the counterpart relation is in a sense stipulated rather than grounded on similarity, and is such that no object has more than one counterpart at a world. This avoids a number of objections Fara and Williamson have recently levelled against counterpart theory generally; their other objections are addressed by enriching the theory with special quantifiers and actuality operators

A Russellian theory of (definite) descriptions takes an utterance of the form ‘The F is G' to express a purely general proposition that affirms the existence of a (contextually) unique F: there is exactly one F [which is C] and it is G. Strawson, by contrast, takes the utterer to presuppose in some sense that there is exactly one salient F, but this is not part of what is asserted; rather, when the presupposition is not met the utterance simply fails to express a (true or false) proposition. A defender of Strawson's approach, however, must square up to what appear to be straightforward counterexamples to the presupposition thesis, and must also provide an account of certain linguistic phenomena that supposedly demand treating descriptions as quantifiers, as the Russellian theory does. In this paper I propose fresh considerations in favour of Strawson's approach. I shift attention from what the utterer presupposes to preconditions for the use of descriptions, and distinguish between referring and predicative uses of descriptions (not to be confused with referential and attributive uses); importantly, the referring and predicative uses have different preconditions, I argue, and these provide some satisfactory responses to the aforementioned challenges facing the Strawsonian.

André Gallois (1998) attempts to defend the occasional identity thesis (OIT), the thesis that objects which are distinct at one time may nonetheless be identical at another time, in the face of two influential lines of argument against it. One argument involves Kripke’s (1971) notion of rigid designation and the other, Leibniz’s law (affirming the indiscernibility of identicals). It is reasonable for advocates of (OIT) to question the picture of rigid designation and the version of Leibniz’s law that these arguments employ, but, the problem is, some form of rigidity is required for one to affirm the occasional identity of objects, and some (restricted) version of Leibniz’s law must be conceded if identity really is involved. Gallois accordingly recommends an account of rigidity and a version of Leibniz’s law to this end.1 We find Gallois’ proposals entirely inadequate to their task. We aim in this paper is to explicate and defend an alternative approach for occasional identity theorists. We do not seek to defend (OIT) per se; our aim, rather, is simply to show that the arguments from rigid designation and Leibniz’s law are inconclusive. Let’s begin with an outline of these arguments

In this note I revive a lingering (albeit dormant) account of rigid designation from the pages of Mind with the aim of laying it to rest. Why let a sleeping dog lie when you can put it down? André Gallois (1986) has proposed an account of rigid designators that allegedly squares with Saul Kripke’s (1980) characterisation of them as terms which designate the same object in all possible worlds, but on which, contra Kripke, identity sentences involving rigid designators may be merely contingently true. This suits Gallois, as he finds the notion of contingent identity coherent. Thus, the thrust of Gallois’ thesis is that his account of rigidity is preferable to Kripke’s because his accommodates a coherent metaphysical viewpoint, whereas Kripke’s doesn’t. Gallois has thwarted one unconvincing challenge (see Carter 1987; Gallois 1988) and his account, as yet, remains untainted. But not for long, I hope.1 Let us assume, for the sake of argument, that the notion of contingent identity is coherent, that, in other words, it makes—or can make—sense to say that certain (possible) objects are identical in one world but distinct in another. What I shall argue here is that Gallois’ account of rigidity would prevent us from expressing the contingent nonidentity of objects; if so, this is a significant failing of the account, for, as it will emerge, clearly Gallois is committed to the contingency of non-identity
