David Chalmers has recently developed a novel strategy of refuting external world skepticism, one he dubs the structuralist solution. In this paper, I make three primary claims: First, structuralism does not vindicate knowledge of other minds, even if it is combined with a functionalist approach to the metaphysics of minds. Second, because structuralism does not vindicate knowledge of other minds, the structuralist solution vindicates far less worldly knowledge than we would hope for from a solution to skepticism. For, solipsism threatens surprisingly vast swathes of worldly knowledge across multiple domains, including at least some knowledge about: political affairs, religious practices, artistic movements, historical events, and cultural trends. Third, the significance of these results exceeds their implications for the structuralist solution; these results suggest that no solution to external world skepticism which does not also solve the problem of other minds will ultimately yield the kind of solution we might have hoped for. Relatedly, these results suggest that the problem of external world skepticism should perhaps be construed as two different problems, since the problem might turn out to require two substantively different solutions, one for knowledge of the kind that is not dependent on other minds and one for knowledge that is.

According to Øystein Linnebo's account of abstractionism, abstraction principles, received as Fregean criteria of identity, can be used to reduce facts about singular reference to objects such as directions and numbers to facts that do not involve such objects. In this article, first I show how the resources of Linnebo's metasemantics successfully handle Dummett's challenge against the referentiality of the singular terms formed by abstraction principles. Then, I argue that Linnebo's metasemantic commitments do not provide us with tools for dispelling the threat of a version of referential indeterminacy, according to which nothing in our use of a singular term, even when it is guided by an associated criterion of identity, could determine which particular object it refers to. I end by examining the bearing of the indeterminacy challenge to Linnebo's treatment of Frege's Caesar Problem: in the absence of an argument against the indeterminacy of reference, it is unclear how numerical expressions could qualify as genuine singular terms.

An increasing number of philosophers argue that indeterminacy is metaphysical (or worldly) in the sense that indeterminacy has its source in the world itself (rather than how the world is represented or known). The standard arguments for metaphysical indeterminacy are centered around the sorites paradox. In this essay, I present a novel argument for metaphysical indeterminacy. I argue that metaphysical indeterminacy follows from the existence of constitutive social construction; there is indeterminacy in the social world because there is indeterminacy in how the social world is constructed.

The linguistic meaning of a word in a language is what fully competent speakers of the language have a grasp of merely in virtue of their semantic competence. The meanings of words sometimes change over time. ‘Meat’ used to mean ‘solid food’, but now means ‘animal flesh eaten as food’. This type of meaning change comes with change of topic, what we are talking about. Many people interested in conceptual engineering have claimed that there is also meaning change where topic is retained. For example, they claim that the meanings of ‘fish’ and ‘pasta’ have undergone such change, and that the meaning of ‘marriage’ would change this way after gay marriages become legal and widely accepted. In this paper, I relate two sets of relatively independent literatures: mainstream philosophy of language and conceptual engineering to argue that on a plausible and widely accepted Minimalist view of meaning that is part and parcel of anti-descriptivism, none of the above sorts of cases involve meaning change with topic retention. I do this by showing how to distinguish minimalism about meaning from the related theses of externalism and anti-individualism about intension and how to separate meaning from intension in a way that allows meaning and topic to remain the same despite changes in intension. The larger lesson is that much like we should not disregard the boundary between the narrowly meaning-related (‘semantics’) and the more broadly communication-related (‘pragmatics’), and we should not disregard the boundary between the former and the more broadly thought-related, conceptual or cognitive (‘cognition’).

Cross-temporal grounding is a type of grounding whereby present facts about the past (for example that Caesar was alive) are explained in terms of past facts (for example that Caesar is alive) rather than in terms of other present facts. This paper lays the foundations for a theory of cross-temporal grounding. After introducing the general idea of a type of grounding connecting facts to past facts, we offer two arguments that past-directed facts require cross-temporal grounds—the ‘argument from intimacy’ and the ‘argument from past explanation’. We then go on to show that cross-temporal grounding statements can be understood as instances of a type of explanation which is perfectly legitimate and intelligible, even if somewhat unusual. Finally, we explain how the logic of grounding can be extended to accommodate cross-temporal grounding statements.

Many philosophers have become sceptical of the use of thought experiments in theorising about personal identity. In large part, this is due to work in experimental philosophy that appears to confirm long-held philosophical suspicions that thought experiments elicit inconsistent judgements about personal identity and hence judgements that are thought to be the product of cognitive biases. If so, these judgements appear to be useless at informing our theories of personal identity. Using the methods of experimental philosophy, we investigate whether people exhibit inconsistent judgements and, if they do, whether these judgements are likely to be the source of cognitive bias or, instead, sensitivity to some relevant factor. We do not find that people's judgements are sensitive to any of the factors we investigate (relevant or irrelevant), nor that people have inconsistent judgements across cases. Rather, people's judgements are best explained by them having a very minimal account of what it takes for a person to survive. Since this pattern of judgements is no reason to think that we are subject to cognitive bias, we see no reason, as things stand, to be sceptical of our judgements.

Our ordinary assertions are often imprecise, insofar as the way we represent things as being only approximates how things are in the actual world. The phenomenon of assertoric imprecision raises a challenge to standard accounts of both the norm of assertion and the connection between semantics and the objects of assertion. After clarifying these problems in detail, I develop a framework for resolving them. Specifically, I argue that the phenomenon of assertoric imprecision motivates a rejection of the widely held belief that a semantic theory for a language associates a single semantic value with each of the simple and complex expressions of that language, relative to the contexts in which they occur. Instead, I propose that we adopt a framework I call semantic pluralism.

According to a standard story, part of what we have in mind when we say that an argument is valid is that it is necessarily truth-preserving: if the premises are true, the conclusion must also be true. But—the story continues—that's not enough, since ‘Roses are red, therefore roses are coloured’, for example, while it may be necessarily truth-preserving, is not so in virtue of form. Thus we arrive at a standard contemporary characterisation of validity: an argument is valid when it is NTP in virtue of form. Here I argue that we can and should drop the N; the resulting account is simpler, less problematic, and performs just as well with examples.
