The phasalist solution to the puzzle of the statue and the piece of clay claims that being a statue is a phase sortal property of the piece of clay, just like being a child is a phase sortal property of a human being. Some philosophers reject this solution because it cannot account for cases where the statue seems to gain and lose parts that the piece of clay does not. I rebut this objection by arguing, contrary to the prevailing view, (...) that the piece of clay is not mereologically constant and might even be highly mereologically flexible. (shrink)

ABSTRACT One simple but relatively neglected solution to the notorious coincidence puzzle of the statue and the piece of clay claims that the property of being a statue is a phase sortal property that the piece of clay instantiates temporarily. I defend this view against some standard objections, by reinforcing it with a novel counterpart-theoretic account of identity under a sortal. This proposal does not require colocation, four-dimensionalism, eliminativism, deflationism, or unorthodox theses about classical identity.

I introduce a new approach to fission puzzles called the Diversified Approach that proceeds by distinguishing different kinds of fission and assimilating each kind to a different ordinary phenomenon, such as breaking apart, replication, or part loss. To illustrate this approach, I apply it to the case of amoebic fission. The upshot is a novel account of amoebic fission according to which the dividing amoeba ceases to exist because it breaks apart. After developing this solution and highlighting some of its (...) advantages, I discuss briefly how the Diversified Approach can be extended to other varieties of fission. (shrink)

Many philosophers believe that the criteria of identity over time for ordinary objects entail that such objects are permanent members of certain sortal kinds. The sortal kinds in question have come to be known as substance sortal kinds. But in this article, I defend a criterion of identity that is suited to phasalism, the view that alleged substance sortals are in fact phase sortals. The criterion I defend is a sortal‐weighted version of a change‐minimizing criterion first discussed by Eli Hirsch. (...) I present this criterion and then argue that it withstands attempts to show that it is inferior to non‐phasalist rivals. (shrink)

One paradigmatic argument from evil against theism claims that, (1) if God exists, then there is no gratuitous evil. But (2) there is gratuitous evil, so (3) God does not exist. I consider three deontological strategies for resisting this argument. Each strategy restructures existing theodicies which deny (2) so that they instead deny (1). The first two strategies are problematic on their own, but their primary weaknesses vanish when they are combined to form the third strategy, resulting in a promising (...) new approach to the problem of evil. (shrink)

One of the standard puzzles in ordinary-object metaphysics concerns what happens when an object and one of its undetached parts apparently begin to coincide. I distinguish two versions of this puzzle: the problem of extraordinary undetached parts and the problem of ordinary undetached parts. Then I present a novel phasalist solution to the problem of ordinary undetached parts. My solution is designed to supplement the recently-defended view that ordinary undetached parts exist but extraordinary ones do not.

Byerly has proposed a novel solution to the gap problem for cosmological arguments. I contend that his strategy can be used to strengthen a wide range of other theistic arguments as well, and also to stitch them together into a cumulative case for theism. I illustrate these points by applying Byerly’s idea about cosmological arguments to teleological arguments.

One objection to the thesis that multilocation is possible claims that, when combined with a preference for parsimonious theories, it leads to the absurd result that we ought to believe the material universe is composed of just one simple particle. I argue that this objection fails.

I present Ned Markosian's episodic account of identity under a sortal, and then use it to sketch a new model of the Trinity. I show that the model can be used to solve at least three important Trinitarian puzzles: the traditional ‘logical problem of the Trinity’, a less-discussed problem that has been dubbed the ‘problem of triunity’, and a problem about the divine processions that has been enjoying increased attention in the recent literature.

Although much has been written about divine knowledge, and some on divine beliefs, virtually nothing has been written about divine credences. In this essay we comparatively assess four views on divine credences: (1) God has only beliefs, not credences; (2) God has both beliefs and credences; (3) God has only credences, not beliefs; and (4) God has neither credences nor beliefs, only knowledge. We weigh the costs and benefits of these four views and draw connections to current discussions in philosophical (...) theology. (shrink)

It is widely held that the classic reassembly model of resurrection faces intractable problems. What happens to someone if God assembles two individuals at the resurrection which are equally good candidates for being the original person? If two or more people, such as a cannibal and the cannibal’s victim, were composed of the same particles at their respective deaths, can they both be resurrected? If they can, who gets the shared particles? And would an attempt to reassemble a long-gone individual (...) result in a genuine resurrection, or merely an intrinsic duplicate of the original person? In this paper, I argue that the first of these problems has, in effect, been solved by defenders of a rival view; I propose a novel solution to the second problem; and I show that the third can be solved by upgrading the naïve reassembly model to a novel variety of reassembly model. (shrink)

Stringent non-consequentialist constraints on permitting horrendous evils pose a formidable challenge to the project of theodicy by limiting the ways in which it is permissible for God to do or allow evil for the sake of bringing about a greater good. I formulate a general and potent argument against all greater-good theodicies from the existence of robust side constraints on permitting evil. Then I contend that the argument fails. I begin by distinguishing between side constraints on doing evil and side (...) constraints on allowing evil, and then I draw on the work of David Lewis and Fiona Woollard to argue that, because of the unique ways that God is related to the world, it is plausible that God can both create and sustain our universe, despite all of its evils, without violating any of these constraints. (shrink)

The phasalist solution to the classic puzzle of the statue and the piece of clay only works for some coincidence puzzles and not others. To address this limitation of phasalism, I develop a novel approach to coincidence puzzles that permits different kinds of coincidence puzzles to be solved in different ways, provided that each solution satisfies certain constraints inspired by the phasalist solution to the statue puzzle. I apply my approach to four different kinds of coincidence puzzles, and I argue (...) that it is no less plausible than rival approaches in the literature. (shrink)

Recently, some authors have argued that experiences of poignant evils provide non-inferential support for crucial premisses in arguments from evil. Careful scrutiny of these experiences suggests that the impermissibility of permitting a horrendous evil might be characterized by a deontological insensitivity to consequences. This has significant implications for the project of theodicy.

John Martin Fischer has argued that Molinism does not constitute a response to the argument that divine foreknowledge is incompatible with human freedom. I argue that T. Ryan Byerly’s recent work on the mechanics of foreknowledge sheds light on this issue. It shows that Fischer’s claim is ambiguous, and that it may turn out to be false on at least one reading, but only if the Molinist can explain how God knows true counterfactuals of freedom.

One problem for Molinism that critics of the view have pressed, and which Molinists have so far done little to address, is that even if there are true counterfactuals of freedom, it is puzzling how God could possibly know them. I defuse this worry by sketching a plausible model of the mechanics of middle knowledge which draws on William Alston’s direct acquaintance account of divine knowledge.

In this article I develop a new problem for the doctrine of the Trinity that I call the Problem of Triunity. Rather than proceeding from the fact that God is one and the persons are many, as the traditional problem of the Trinity does, the problem of triunity proceeds from the fact that, in one sense or another, God is many, and yet each divine person on his own is just one.

The recent literature on the nature of persistence features a handful of imaginative cases in which an object seems to colocate with itself. So far, discussion of these cases has focused primarily on how they defy the standard endurantist approaches to the problem of temporary intrinsics. But in this article, I set that issue aside and argue that cases of apparent self-colocation also pose another problem for the endurantist. While the perdurantist seems to have a fairly straightforward account of self-colocation, (...) the endurantist has a hard time saying exactly what it would be for an object to be self-colocated. After introducing this problem and explaining how the perdurantist can circumvent it with little difficulty, I discuss a number of tempting endurantist solutions that ultimately fail. Then I suggest an endurantist solution which I think is more promising, but which requires the endurantist to deny that apparent cases of self-colocation are genuine cases of self-colocation. (shrink)

I develop a model of providence on which God brings about good states of affairs by means of evil states of affairs, but without intending the latter. The model's key ingredient is a backward-looking counterpart of the distinction between intended and merely foreseen consequences of an action: namely, a distinction between intended and merely foreseen means to an end. The model enables greater-good theodicies to avoid worries about whether a perfect being could intend evil.

Some philosophers defend the possibility of synchronic multilocation, and have even used it to defend other substantive metaphysical theses. But just how strong is the case for the possibility of synchronic multilocation? The answer to this question depends in part on whether synchronic multilocation is wedded to other controversial metaphysical notions. In this paper, I consider whether the possibility of synchronic multilocation depends on the possibility of time travel, and I conclude that the answer hinges on the nature of time (...) and persistence.

William L. Rowe’s argument against divine freedom has drawn considerable attention from theist philosophers. One reply to Rowe’s argument that has emerged in the recent literature appeals to modified accounts of libertarian freedom which have the result that God may be free even if he necessarily actualizes the best possible world. Though in many ways attractive, this approach appears to lead to the damning consequence of modal collapse i.e., that the actual world is the only possible world. But appearances can (...) be deceiving, and in this paper I argue that the threat of modal collapse dissolves when we consider Alvin Plantinga’s critique of the purportedly Leibnizian notion that God can actualize any possible world, and incorporate the implications of this critique into the divine freedom debate. Developing a suggestion by Edward R. Wierenga, I argue first that the modal collapse objection fails within a Molinist context, and then I extend the discussion beyond that context to show that the objection also fails on the assumption that Molinism is false.

Collaboration is increasingly popular across academia. Collaborative work raises certain ethical questions, however. How will the fruits of collaboration be divided? How will the work for the collaborative project be split? In this paper, we consider the following question in particular. Are there ways in which these divisions systematically disadvantage certain groups? -/- We use evolutionary game theoretic models to address this question. First, we discuss results from O'Connor and Bruner (unpublished). In this paper, we show that underrepresented groups in (...) academia can be disadvantaged in such situations by dint of their small numbers. Second, we present novel results exploring how the hierarchical structure of academia can lead to bargaining disadvantage. We investigate models where one actor has a higher baseline of academic success, less to lose if collaboration goes south, or greater rewards for non-collaborative work. We show that in these situations, the less powerful partner is disadvantaged in bargaining over collaboration. (shrink)

Margaret MacDonald (1907–56) was a central figure in the history of early analytic philosophy in Britain due to both her editorial work as well as her own writings. While her later work on aesthetics and political philosophy has recently received attention, her early writings in the 1930s present a coherent and, for its time, strikingly original blend of common-sense and scientific philosophy. In these papers, MacDonald tackles the central problems of philosophy of her day: verification, the problem of induction, and (...) the relationship between philosophical and scientific method. MacDonald’s philosophy of science starts from the principle that we should carefully analyse the elements of scientific practice (particularly its temporal features) and the ways that scientists describe that practice. That is, she applies the techniques of ordinary language philosophy to actual scientific language. MacDonald shows how ‘scientific common-sense’ is inconsistent with both of the dominant schools of philosophy of her day. Bringing MacDonald back into the story of analytic philosophy corrects the impression that in early analytic philosophy, there are fundamental dichotomies between the style of Moore and Wittgenstein, on the one hand, and the Vienna Circle on the other.

Recent work in cognitive science of religion (CSR) is beginning to converge on a very interesting thesis—that, given the ordinary features of human minds operating in typical human environments, we are naturally disposed to believe in the existence of gods, among other religious ideas (e.g., seeAtran [2002], Barrett [2004; 2012], Bering [2011], Boyer [2001], Guthrie [1993], McCauley [2011], Pyysiäinen [2004; 2009]). In this paper, we explore whether such a discovery ultimately helps or hurts the atheist position—whether, for example, it lends (...) credence to atheism by explaining away religious belief or whether it actually strengthens some already powerful arguments against atheism in the relevant philosophical literature.We argue that the recent discoveries of CSR hurt, not help, the atheist position—that CSR, if anything, should not give atheists epistemic assurance.

Benedict de Spinoza is one of the most controversial and enigmatic thinkers in the history of philosophy. His greatest work, Ethics (1677), developed a comprehensive philosophical system and argued that God and Nature are identical. His scandalous Theological-Political Treatise (1670) provoked outrage during his lifetime due to its biblical criticism, anticlericalism, and defense of the freedom to philosophize. Together, these works earned Spinoza a reputation as a singularly radical thinker. -/- In this book, Steinberg and Viljanen offer a concise and (...) up-to-date account of Spinoza’s thought and its philosophical legacy. They explore the full range of Spinoza’s ideas, from politics and theology to ontology and epistemology. Drawing broadly on Spinoza’s impressive oeuvre, they have crafted a lucid introduction for readers unfamiliar with this important philosopher, as well as a nuanced and enlightening study for more experienced readers.

Symposium on Nietzsche's Constructivism (Routledge, 2018), replies to Adler, Cabrera, Doyle, Migotti, Sinhababu, Pedersen.

In this paper we use an experimental approach to investigate how linguistic conventions can emerge in a society without explicit agreement. As a starting point we consider the signaling game introduced by Lewis. We find that in experimental settings, small groups can quickly develop conventions of signal meaning in these games. We also investigate versions of the game where the theoretical literature indicates that meaning will be less likely to arise—when there are more than two states for actors to transfer (...) meaning about and when some states are more likely than others. In these cases, we find that actors are less likely to arrive at strategies where signals have clear conventional meaning. We conclude with a proposal for extending the use of the methodology of experimental economics in experimental philosophy. (shrink)

Mainstream teleosemantics is the view that mental representation should be understood in terms of biological functions, which, in turn, should be understood in terms of selection processes. One of the traditional criticisms of teleosemantics is the problem of novel contents: how can teleosemantics explain our ability to represent properties that are evolutionarily novel? In response, some have argued that by generalizing the notion of a selection process to include phenomena such as operant conditioning, and the neural selection that underlies it, (...) we can resolve this problem. Here, we do four things: we develop this suggestion in a rigorous way through a simple example, we draw on recent neurobiological research to support its empirical plausibility, we defend the move from a host of objections in the literature, and we sketch how the picture can be extended to help us think about more complex “conceptual” representations and not just perceptual ones.

Perhaps the most fundamental disagreement concerning Nietzsche's view of metaphysics is that some commentators believe Nietzsche has a positive, systematic metaphysical project, and others deny this. Those who deny it hold that Nietzsche believes metaphysics has a special problem, that is, a distinctively problematic feature that distinguishes metaphysics from other areas of philosophy. In this paper, I investigate important features of Nietzsche's metametaphysics in order to argue that Nietzsche does not, in fact, think metaphysics has a special problem. The result (...) is that, against a long-standing view held in the literature, we should be reading Nietzsche as a metaphysician. (shrink)

I present and defend the generalized selected effects theory (GSE) of function. According to GSE, the function of a trait consists in the activity that contributed to its bearer’s differential reproduction, or differential retention, within a population. Unlike the traditional selected effects (SE) theory, it does not require that the functional trait helped its bearer reproduce; differential retention is enough. Although the core theory has been presented previously, I go significantly beyond those presentations by providing a new argument for GSE (...) and defending it from a recent objection. I also sketch its implications for teleosemantics and philosophy of medicine. (shrink)

Moral grandstanding is a pervasive feature of public discourse. Many of us can likely recognize that we have engaged in grandstanding at one time or another. While there is nothing new about the phenomenon of grandstanding, we think that it has not received the philosophical attention it deserves. In this essay, we provide an account of moral grandstanding as the use of public discourse for moral self-promotion. We then show that our account, with support from some standard theses of social (...) psychology, explains the characteristic ways that grandstanding is manifested in public moral discourse. We conclude by arguing that there are good reasons to think that moral grandstanding is typically morally bad and should be avoided. (shrink)

his paper is an excerpt from a larger project that aims to open a new pathway into Spinoza's Ethics by formally reconstructing an initial fragment of this text. The semantic backbone of the project is a custom-made Spinozian model theory that lays out some of the formal prerequisites for more ne-grained investigations into Spinoza's fundamental ontology and modal metaphysics. We implement Spinoza's theory of attributes using many-sorted models with a rich system of identity that allows us to clarify the puzzling (...) status of such logical principles as the Substitution of Identicals and Transitivity of Identity in Spinoza's thought. The intensional structure of our Spinozian models also captures his proposal that states of a airs can be necessitated or excluded by the essences of particular things, an essence-relative modality that should be of interest to philosophers who have sought to rehabilitate the concept of essence in contemporary analytic metaphysics.

When speakers utter conflicting moral sentences, it seems clear that they disagree. It has often been suggested that the fact that the speakers disagree gives us evidence for a claim about the semantics of the sentences they are uttering. Specifically, it has been suggested that the existence of the disagreement gives us reason to infer that there must be an incompatibility between the contents of these sentences. This inference then plays a key role in a now-standard argument against certain theories (...) in moral semantics. In this paper, we introduce new evidence that bears on this debate. We show that there are moral conflict cases in which people are inclined to say both that the two speakers disagree and that it is not the case at least one of them must be saying something incorrect. We then explore how we might understand such disagreements. As a proof of concept, we sketch an account of the concept of disagreement and an independently motivated theory of moral semantics which, together, explain the possibility of such cases. (shrink)

Recent scholarship has considered the requirements of justice and economic regimes in the work of John Rawls. This work has not delved into the requirements of justice and liberal socialism as deeply as the work that has been done on property-owning democracy. A thorough treatment of liberal socialism and the requirements of justice is needed. This paper seeks to begin to fill this gap. In particular, it needs to be shown if liberal socialism fully answers the requirements of justice better (...) than property-owning democracy. It will be argued that liberal socialism does significantly better in realizing the two principles. This paper has the following structure, first, an overview of Rawls' position on economic regimes, capitalism, and the requirements of justice will be presented. In particular, how the two principles work in tandem to meet the demands of distributive justice will be considered. Second, a review of property-owning democracy will be conducted. Finally, liberal socialism will be examined and discussed as an economic regime that answers the requirements of justice more fully. (shrink)

Frankfurt cases are supposed to provide us with counterexamples to the principle of alternative possibilities. Among the most well known responses to these cases is what John Fischer has dubbed the flicker of freedom strategy. Here we revisit a version of this strategy, which we refer to as the fine-grained response. Although a number of philosophers, including some who are otherwise unsympathetic to Frankfurt’s argument, have dismissed the fine grained response, we believe there is a good deal to be said (...) on its behalf. We argue, in particular, that reflection on certain cases involving omissions undermines the main objections to the response and also provides the groundwork for an argument in support of it.

This article presents a distinct sense of ‘mechanism’, which I call the functional sense of mechanism. According to this sense, mechanisms serve functions, and this fact places substantive restrictions on the kinds of system activities ‘for which’ there can be a mechanism. On this view, there are no mechanisms for pathology; pathologies result from disrupting mechanisms for functions. Second, on this sense, natural selection is probably not a mechanism for evolution because it does not serve a function. After distinguishing this (...) sense fromsimilar explications of ‘mechanism’, I argue that it is ubiquitous in biology and has valuable epistemic benefits. (shrink)

There is a certain metaphor that has enjoyed tremendous longevity in the evolution of ageing literature. According to this metaphor, nature has a certain goal or purpose, the perpetuation of the species, or, alternatively, the reproductive success of the individual. In relation to this goal, the individual organism has a function, job, or task, namely, to breed and, in some species, to raise its brood to maturity. On this picture, those who cannot, or can no longer, reproduce are somehow invisible (...) to, or even dispensable to, the evolutionary process. Here, I argue that the metaphor should be discarded, not on the grounds that it is a metaphor, but on the grounds that this particular metaphor distorts our understanding of the evolution of ageing. One reason the metaphor is problematic is that it frames senescence and death as nature’s verdict on the value of older individuals. Instead, we should explore a different metaphor: the lengthy post-reproductive period in humans and some other animals is not an accident of culture, but designed by nature for the purpose of supporting and guiding younger generations. On this alternate picture, different stages of life have their own evolutionary rationales, their distinctive design features, their special mandates. (shrink)

I distinguish two forms of pluralism about biological functions, between-discipline pluralism and within-discipline pluralism. Between-discipline pluralism holds that different theories of function are appropriate for different subdisciplines of biology and psychology. I provide reasons for rejecting this view. Instead, I recommend within-discipline pluralism, which emphasizes the plurality of function concepts at play within any given subdiscipline of biology and psychology.

Both in everyday life and in moral philosophy, many think that our own past wrongdoing can undermine our standing to indignantly blame others for similar wrongdoing. In recent literature on the ethics of blame, we find two different kinds of explanation for this. Relative moral status accounts hold that to have standing to blame, you must be better than the person you are blaming, in terms of compliance with the norm. Fault-based accounts hold that those who blame others for things (...) of which they are also guilty exhibit familiar moral faults, such as making an exception of oneself, and that these faults explain why they lack standing. I argue in support of relative moral status accounts, showing that they both better trace our practice of dismissing blame on the basis of lack of standing, and that they have more explanatory resources than has been appreciated.

Evolutionary debunking arguments claim that evolution has influenced our moral faculties in such a way that, if moral realism is true, then we have no positive moral knowledge. I present several popular objections to the standard version of this argument, then give a new EDA that has clear advantages in responding to these objections. Whereas the Standard EDA argues that evolution has selected for many moral beliefs with certain contents, this New EDA claims that evolution has selected for one belief: (...) belief in the claim that categorical reasons exist. If moral realism is true, then this claim is entailed by all positive moral claims, and belief in it is defeated due to evolutionary influence. This entails that if realism is true, then we have no positive moral knowledge. While there may be objections against this New EDA, it is much stronger than the Standard EDA, and one realists ought to worry about. (shrink)

Theories of function are conventionally divided up into historical and ahistorical ones. Proponents of ahistorical theories often cite the ahistoricity of their accounts as a major virtue. Here, I argue that none of the mainstream “ahistorical” accounts are actually ahistorical. All of them embed, implicitly or explicitly, an appeal to history. In Boorse’s goal-contribution account, history is latent in the idea of statistical-typicality. In the propensity theory, history is implicit in the idea of a species’ natural habitat. In the causal (...) role theory, history is required for making sense of dysfunction. I elaborate some consequences for the functions debate. (shrink)

In this paper, I take up one of Wang Yangming’s most audacious philosophical claims, which is that an achievement that is entirely concerned with correcting one’s own inner states, called “establishing sincerity” (licheng 立誠) can help one to fully grasp (jin 盡) all ethically pertinent matters, including those that would seem to require some ability to know or track facts about the wider world (e.g., facts about people very different from ourselves, facts about the needs of plants and animals). Wang (...) makes a claim to this effect in some of his letters and recorded discussions. -/- I begin with a brief, historical reconstruction of what Wang means by “establishing sincerity” and then turn to two sets of controversies regarding his audacious claim. The first has to do with how we should understand the proposal that establishing sincerity helps or positions a person to fully grasp all ethically significant concerns. On the interpretation of Chen Lai 陳來, Wang doesn’t think that establishing sincerity is sufficient by itself to have this grasp, only that it lays a necessary psychological foundation for all attempts to do so, so that it leaves much more work to do. I largely agree with Chen’s reading but find it isn’t strong enough to capture what’s most important and controversial about Wang’s view. On my stronger reading, Wang doesn’t just think that establishing sincerity provides a necessary foundation for a complete grasp, he also thinks that it describes the most difficult and demanding step or part of the process – the other steps come much more naturally and easily. The second set of controversies has to do with whether we can preserve Wang’s core account of virtuous moral agency without his strong ethical nativism, according to which we have an inherent capacity and disposition to track what is ethically important or salient about people and things very much unlike ourselves. I consider some arguments and interpretations of Wang’s thought that might allow us to bypass his nativist presuppositions, and conclude that they do not succeed. Even if we cannot accept his ethical nativism, however, there is a range of important ethical norms for which Wang’s prescriptions are powerful and prudent. The result of this study, I hope, will be an account of Wang’s thought which better positions us to see what parts are (and are not) worth bringing to ongoing debates about the nature of ethics, moral knowledge, and moral virtue.

Value claims about ecological entities, their functionality, and properties take center stage in so-called “ecological” ethical and aesthetic theories. For example, the claim that the biodiversity in an old-growth forest imbues it with “value in and for itself” is an explicit value claim about an ecological property. And the claim that one can study “the aesthetics of nature, including natural objects...such as ecosystems” presupposes that natural instances of a type of ecological entity exist and can be regarded as more or (...) less aesthetically valuable. My discussion below will bear wide implications for how claims like... (shrink)

It is widely agreed that the intelligibility of modal metaphysics has been vindicated. Quine's arguments to the contrary supposedly confused analyticity with metaphysical necessity, and rigid with non-rigid designators.2 But even if modal metaphysics is intelligible, it could be misconceived. It could be that metaphysical necessity is not absolute necessity – the strictest real notion of necessity – and that no proposition of traditional metaphysical interest is necessary in every real sense. If there were nothing otherwise “uniquely metaphysically significant” about (...) metaphysical necessity, then paradigmatic metaphysical necessities would be necessary in one sense of “necessary”, not necessary in another, and that would be it. The question of whether they were necessary simpliciter would be like the question of whether the Parallel Postulate is true simpliciter – understood as a pure mathematical conjecture, rather than as a hypothesis about physical spacetime. In a sense, the latter question has no objective answer. In this article, I argue that paradigmatic questions of modal metaphysics are like the Parallel Postulate question. I then discuss the deflationary ramifications of this argument. I conclude with an alternative conception of the space of possibility. According to this conception, there is no objective boundary between possibility and impossibility. Along the way, I sketch an analogy between modal metaphysics and set theory. (shrink)

The W-defense is among the most prominent arguments for the principle of alternative possibilities (PAP). Here I offer some considerations in support of the W-defense and respond to what I see as the most forceful objections to it to date. My response to these objections invokes the well-known flicker of freedom response to Frankfurt cases. I argue that the W-defense and the flicker response are mutually reinforcing and together yield a compelling defense of PAP.

How does Aristotle think about sentences like ‘Every x is y’ in the Prior Analytics? A recently popular answer conceives of these sentences as expressing a mereological relationship between x and y: the sentence is true just in case x is, in some sense, a part of y. I argue that the motivations for this interpretation have so far not been compelling. I provide a new justification for the mereological interpretation. First, I prove a very general algebraic soundness and completeness (...) result that unifies the most important soundness and completeness results to date. Then I argue that this result vindicates the mereological interpretation. In contrast to previous interpretations, this argument shows how Aristotle’s conception of predication in mereological terms can do important logical work. (shrink)

A common misunderstanding of the selected effects theory of function is that natural selection operating over an evolutionary time scale is the only functionbestowing process in the natural world. This construal of the selected effects theory conflicts with the existence and ubiquity of neurobiological functions that are evolutionary novel, such as structures underlying reading ability. This conflict has suggested to some that, while the selected effects theory may be relevant to some areas of evolutionary biology, its relevance to neuroscience is (...) marginal. This line of reasoning, however, neglects the fact that synapses, entire neurons, and potentially groups of neurons can undergo a type of selection analogous to natural selection operating over an evolutionary time scale. In the following, I argue that neural selection should be construed, by the selected effect theorist, as a distinct type of function-bestowing process in addition to natural selection. After explicating a generalized selected effects theory of function and distinguishing it from similar attempts to extend the selected effects theory, I do four things. First, I show how it allows one to identify neural selection as a distinct function-bestowing process, in contrast to other forms of neural structure formation such as neural construction. Second, I defend the view from one major criticism, and in so doing I clarify the content of the view. Third, I examine drug addiction to show the potential relevance of neural selection to neuroscientific and psychological research. Finally, I endorse a modest pluralism of function concepts within biology. (shrink)

Nietzsche’s presentation of the eternal recurrence in Gay Science 341 is often viewed as a practical thought experiment meant to radically transform us. But exactly why and how we are supposed to be transformed is not clear. I contend that addressing these issues requires taking a close look at the psychological setting of the passage. The eternal recurrence is presented in our “loneliest loneliness.” I argue that facing the eternal recurrence from a state of profound loneliness both motivates self-transformation and (...) contributes toward helping us succeed at that project.
