Fictionality and Imagination,Revisited

I present and discuss a counterexample to Kendall Walton's necessary condition for fictionality that arises from considering serial fictions. I argue that although Walton has not in fact provided a necessary condition for fictionality, a more complex version of Walton's condition is immune from the counterexample.     

The Problem of Modernism and Critical Refusal: Bradley and Lamarque on Form/Content Unity

In this article I revisit A. C. Bradley's account of form/content unity through the lens of both Peter Kivy's and Peter Lamarque's recent work on Bradley's lecture “Poetry for Poetry's Sake.” I argue that Lamarque gives a superior account of Bradley's argument. However, Lamarque claims that form/content unity should be understood as an imposition applied by the reader to poetry. Working with the counterexample of modernist poetry, I throw doubt on both this claim and some associated presuppositions found in Lamarque's account. Modernist poetry appears to intermittently fail to exhibit form/content unity; its unique value also appears bound up with this intermittent failure. However—against the moderates, like Kivy and Kelly Dean Jolley, who this counterexample may seem to support—I claim Lamarque is nonetheless correct that form/content unity is intrinsic in response to poetic value. I argue form/content unity should be seen as a demand, which poems (like modernist poetry) can intentionally frustrate.     

Unsafe Knowledge

Ernest Sosa has argued that if someone knows that p, then his belief that p is “safe”. and Timothy Williamson has agreed. In this paper I argue that safety, as defined by Sosa, is not a necessary condition on knowledge – that we can have unsafe knowledge. I present Sosa’s definition of safety and a counterexample to it as a necessary condition on knowledge. I also argue that Sosa’s most recent refinements to the notion of safety don’t help him to avoid the counterexample. I consider three replies on behalf of the defender of safety, and find them all wanting. Finally, I offer a tentative diagnosis of my counterexample.     

Credence and self-location

All parties to the Sleeping Beauty debate agree that it shows that some cherished principle of rationality has to go. Thirders think that it is Conditionalization and Reflection that must be given up or modified; halfers think that it is the Principal Principle. I offer an analysis of the Sleeping Beauty puzzle that allows us to retain all three principles. In brief, I argue that Sleeping Beauty’s credence in the uncentered proposition that the coin came up heads should be 1/2, but her credence in the centered proposition that the coin came up heads and it is Monday should be 1/3. I trace the source of the earlier mistakes to an unquestioned assumption in the debate, namely that an uncentered proposition is just a special kind of centered proposition. I argue that the falsity of this assumption is the real lesson of the Sleeping Beauty case.     

Dispositions And Mimickers

In this paper I put forward a counterexample against Lewis’s reformed conditional analysis of fragility and then refute a possible response by Lewis. And I go on to argue that Lewis can overcome the counterexample by excluding fragility-mimickers from the stimulus appropriate to the concept of fragility.     

Why Truthmaking Is Not a Case of Grounding

Truthmaker theorists often express their core commitment by saying that truth is grounded in being, and grounding theorists often take truthmaking to be a paradigm case of grounding. But I will argue that truthmaking is not a case of grounding. What is crucial for understanding truthmaking is not grounding but rather meaning (in a broad sense including reference). Truth is still constrained by how things are, so even if (so-called) truthmakers don't play a role in grounding truths, the methodological program of truthmaker theory survives. Here I lay out my understanding of truth and truthmaking, and distinguish two conceptions of grounding. I argue that truthmaking is not plausibly seen as a case of grounding on either conception. I argue further that treating truthmaking as grounding threatens to violate a plausible irreflexivity principle, and makes trouble for the view that grounding is transitive. I then suggest that there is no genuine relation of truthmaking (which there would have to be if it were a true case of grounding). Finally, I show how the core insights of truthmaker theory are preserved by the understanding of truthmaking that I favor.     

Nothing but the Evidential Considerations?

A number of philosophers have claimed that non-evidential considerations cannot play a role in doxastic deliberation as motivating reasons to believe a proposition. This claim, interesting in its own right, naturally lends itself to use in a range of arguments for a wide array of substantive philosophical theses. I argue, by way of a counterexample, that the claim to which all these arguments appeal is false. I then consider, and reply to, seven objections to my counterexample. Finally, as a way of softening the blow, I show how the counterexample itself suggests a plausible diagnosis of why this claim has seemed so plausible to so many.     

Quasi-miracles,typicality, and counterfactuals

If one flips an unbiased coin a million times, there are 2^1,000,000 series of possible heads/tails sequences, any one of which might be the sequence that obtains, and each of which is equally likely to obtain. So it seems (1) ‘If I had tossed a fair coin one million times, it might have landed heads every time’ is true. But as several authors have pointed out, (2) ‘If I had tossed a fair coin a million times, it wouldn’t have come up heads every time’ will be counted as true in everyday contexts. And according to David Lewis’ influential semantics for counterfactuals, (1) and (2) are contradictories. We have a puzzle. We must either (A) deny that (2) is true, (B) deny that (1) is true, or (C) deny that (1) and (2) are contradictories, thus rejecting Lewis’ semantics. In this paper I discuss and criticize the proposals of David Lewis and more recently J. Robert G. Williams which solve the puzzle by taking option (B). I argue that we should opt for either (A) or (C).     

Knowing Is Not Enough

I consider the rule of assertion according to which knowledge is sufficient for epistemically proper assertion. I examine a counterexample to this rule recently proposed by Jennifer Lackey. I present three responses to this counterexample. The first two, I argue, highlight some flaws in the counterexample. But the third response fails. The lessons I draw from examining these three responses allow me to propose two counterexamples to the sufficiency rule that are similar to Lackey’s but avoid its problems.     

Why Is a Valid Inference a Good Inference?

True beliefs and truth‐preserving inferences are, in some sense, good beliefs and good inferences. When an inference is valid though, it is not merely truth‐preserving, but truth‐preserving in all cases. This motivates my question: I consider a Modus Ponens inference, and I ask what its validity in particular contributes to the explanation of why the inference is, in any sense, a good inference. I consider the question under three different definitions of ‘case’, and hence of ‘validity’: (i) the orthodox definition given in terms of interpretations or models, (ii) a metaphysical definition given in terms of possible worlds, and (iii) a substitutional definition defended by Quine. I argue that the orthodox notion is poorly suited to explain what's good about a Modus Ponens inference. I argue that there is something good that is explained by a certain kind of truth across possible worlds, but the explanation is not provided by metaphysical validity in particular; nothing of value is explained by truth across all possible worlds. Finally, I argue that the substitutional notion of validity allows us to correctly explain what is good about a valid inference.     

ETERNAL TRUTHS AND CARTESIAN CIRCULARITY

Bennett has said that ‘Voluntarism casts no useful light on those aspects of the Meditations that have received the most attention: the truth rule, divine veracity, the relation between those, the Cartesian Circle’.¹ In this paper, I shall draw together various strands from recent Descartes scholarship to argue that this is entirely false. When Descartes's voluntarism is understood as central to his epistemological project, not only does it allow us to make more sense of what he says on all these issues, but also it allows us to see what he says as, on certain assumptions, unassailable. The only difficulty that then remains is that these assumptions are widely held to be necessarily false.     

Spinoza's Proof of Necessitarianism

This paper consists of four sections. The first section considers what the proof of necessitarianism in Spinoza's system requires. Also in the first section, Jonathan Bennett's (1984) reading of lpl6 as involving a commitment to necessitarianism is presented and accepted. The second section evaluates Bennett's suggestion how Spinoza might have been led to conclude necessitarianism from his basic assumptions. The third section of the paper is devoted to Don Garrett's (1991) interpretation of Spinoza's proof. I argue that Bennett's and Garrett's interpretations of Spinoza's necessitarianism have shortcomings which justify an attempt to offer an alternative proof. In the proof given in the fourth section, it is argued that Spinoza derived necessitarianism from the conjunction of the following principles: (i) necessary existence of the substances; (ii) substance-property ontology; (iii) superessentialism; and (iv) the 'no shared attribute'thesis.     

Conditional Excluded Middle

In this essay I renew the case for Conditional Excluded Middle (CXM) in light of recent developments in the semantics of the subjunctive conditional. I argue that Michael Tooley’s recent backward causation counterexample to the Stalnaker-Lewis comparative world similarity semantics undermines the strongest argument against CXM, and I offer a new, principled argument for the validity of CXM that is in no way undermined by Tooley’s counterexample. Finally, I formulate a simple semantics for the subjunctive conditional that is consistent with both CXM and Tooley’s counterexample.

Epistemic Value and the New Evil Demon

In this article I argue that the value of epistemic justification cannot be adequately explained as being instrumental to truth. I intend to show that false belief, which is no means to truth, can nevertheless still be of epistemic value. This in turn will make a good prima facie case that justification is valuable for its own sake. If this is right, we will have also found reason to think that truth value monism is false: assuming that true belief does have value, there is more of final epistemic value than mere true belief.     

How Pseudo-hypotheses Defeat a Non-Bayesian Theory of Evidence: Reply to Bandyopadhyay,Taper, and Brittan

Bandyopadhyay, Taper, and Brittan (BTB) advance a measure of evidential support that first appeared in the statistical and philosophical literature four decades ago and have been extensively discussed since. I have argued elsewhere, however, that it is vulnerable to a simple counterexample. BTB claim that the counterexample is flawed because it conflates evidence with confirmation. In this reply, I argue that the counterexample stands, and is fatal to their theory.     

Bennett on Parts Twice Over

In this paper I outline the main features of Karen Bennett’s (Australasian Journal of Philosophy 1–21, 2011) non-classical mereology, and identify its methodological costs. I argue that Bennett’s mereology cannot account for the composition of structural universals because it cannot explain the mereological difference between isomeric universals, such as being butane and being isobutane. I consider responses, which come at costs to the view.     

Theorizing about truth outside of one’s own language

A theory of truth is language-transcendent if it ascribes truth conditions to truth-bearers that are not expressible in (or translatable to) our natural language; a theory is language-immanent if it is not language-transcendent. In this paper, I argue for the following theses. (1) Whether the correct theory of truth is language-transcendent or language-immanent will have significant consequences for general philosophy. Prima facie, a language-transcendent theory is preferable. However, (2) language-transcendent theories tend to require substantive metaphysical commitments concerning truth. Deflationist theories are particularly interesting in this context. I argue that, if deflationism is to remain consistent with its motivations, then it must opt for a language-immanent conception of truth.

     

Semantic emphasis in causal sentences

A shift in emphasis can change the truth-value of a singular causal sentence. This poses a challenge to the view that singular sentences predicate a relation. I argue that emphasized causal sentences conjoin predication of a causal relation between events with predication of a relation of causal relevance between states of affairs (or perhaps facts). This is superior to the treatments of such sentences offered by Achinstein, Dretske, Kim, Sanford, Bennett, and Levin. My proposal affords clarity regarding logical structure, at least at a certain level of detail. It makes the relation between the content of an emphasized causal sentence and the unemphasized version clear. It answers some questions about the ontological requirements of the truth of emphasized causal sentences, without introducing new entities (as do some other accounts) or unacceptable consequences for identity and individuation of events.     

Simplicity as a criterion of theory choice in metaphysics

Metaphysicians frequently appeal to the idea that theoretical simplicity is truth conducive in metaphysics, in the sense that, all other things being equal, simpler metaphysical theories are more likely to be true. In this paper I defend the notion that theoretical simplicity is truth conducive in metaphysics, against several recent objections. I do not give any direct arguments for the thesis that simplicity is truth conducive in metaphysics, since I am aware of no such arguments. I do argue, however, that there is no special problem with the notion that simplicity is truth conducive in metaphysics. More specifically, I argue that if you accept the idea that simplicity is truth conducive in science, then it would be objectionably arbitrary to reject the idea that simplicity is truth conducive in metaphysics.     

Rethinking the videogame case: trying and intending

In this paper, I defend the view that a person performs an action A intentionally only if she intends to A against Michael Bratman’s alleged counterexample to it: the videogame case. I object that Bratman is mistaken in assuming that the consistency among an agent’s intentions is about the consistency among intended goals or objectives. Instead, I argue that the real reason why an agent’s intentions need to be consistent with each other is due to the necessity of the compatibility of corresponding efforts of trying. But unfortunately for Bratman, this efforts-based consistency constraint – as a replacement of the objectives-based consistency constraint – cannot save the videogame case.
