It is widely held that every person is a person essentially, where being a person is having special mental properties such as intelligence and self-consciousness. It follows that nothing can acquire or lose these properties. The paper argues that this rules out all familiar psychological-continuity views of personal identity over time. It also faces grave difficulties in accounting for the mental powers of human beings who are not intelligent and self-conscious, such as foetuses and those with dementia.

The Standard View of personal identity says that someone who exists now can exist at another time only if there is continuity of her mental contents or capacities. But no person is psychologically continuous with a fetus, for a fetus, at least early in its career. has no mental features at all. So the Standard View entails that no person was ever a fetus---contrary to the popular assumption that an unthinking fetus is a potential person. It is also mysterious what (...) does ordinarily happen to a human fetus, if it does not come to be a person. Although an extremely complex variant of the Standard View may allow one to persist without psychological continuity before one becomes a person but not afterwards, a far simpler solution is to accept a radically non-psychological account of our identity.

This paper—written for nonspecialist readers—asks whether life after death is in any sense possible given the apparent fact that after we die our remains decay to the point where only randomly scattered atoms remain. The paper argues that this is possible only if our remains are not in fact dispersed in this way, and discusses how that might be the case. -/- 1. Life After Death -- 2. Total Destruction -- 3.

One big question in biology is what life is, but another is how life divides into living things. This is the problem of biological individuality. Proposed statements of the problem have been vague and incomplete. And proposed theories of biological individuality are not detailed enough to solve the problem even if they are correct. The root of these troubles is that their authors have not recognized the metaphysical claims presupposed in their statement of the problem. Making these claims explicit will (...) enable us to see better what the problem is and what form a solution to it would need to have. (shrink)

In special cases of partial twinning, two heads, each supporting a more-orless normal human mental life, emerge from a single torso. It is often argued that there must be two people in such a case, even if there is only one biological organism. That would pose a problem for ‘animalism’, the view that people are organisms. The paper argues that it is very hard to say what sort of non-organisms the people in such cases would be. Reflection on partial twinning (...) is no more comfortable for those who think we’re not organisms than for those who think we are. We may have to accept that a single person could have two separate mental lives. (shrink)

Transhumanists want to free us from the constraints imposed by our humanity by means of “uploading”: extracting information from the brain, transferring it to a computer, and using it to create a purely electronic person there. That is supposed to move us from our human bodies to computers. This presupposes that a human being could literally move to a computer by a mere transfer of information. The chapter questions this assumption, then asks whether the procedure might be just as good, (...) as far as our interests go, even if it could not move us to a computer. (shrink)

Robert Talisse and Scott Aikin have argued that substantive versions of value pluralism are incompatible with pragmatism, and that all such versions of pluralism must necessarily collapse into versions of strong metaphysical pluralism. They also argue that any strong version of value pluralism is incompatible with pragmatism’s meliorist commitment and will block the road of inquiry. I defend the compatibility of a version of value pluralism (the strong epistemic pluralism of John Rawls) with pragmatism, and offer counterarguments to all of (...) these claims. (shrink)

In this paper we compare the propositional logic of Frege’s Grundgesetze der Arithmetik to modern propositional systems, and show that Frege does not have a separable propositional logic, definable in terms of primitives of Grundgesetze, that corresponds to modern formulations of the logic of “not”, “and”, “or”, and “if…then…”. Along the way we prove a number of novel results about the system of propositional logic found in Grundgesetze, and the broader system obtained by including identity. In particular, we show that (...) the propositional connectives that are definable in terms of Frege’s horizontal, negation, and conditional are exactly the connectives that fuse with the horizontal, and we show that the logical operators that are definable in terms of the horizontal, negation, the conditional, and identity are exactly the operators that are invariant with respect to permutations on the domain that leave the truth-values fixed. We conclude with some general observations regarding how Frege understood his logic, and how this understanding differs from modern views. (shrink)

Arguments from disagreement against moral realism begin by calling attention to widespread, fundamental moral disagreement among a certain group of people. Then, some skeptical or anti-realist-friendly conclusion is drawn. Chapter 2 proposes that arguments from disagreement share a structure that makes them vulnerable to a single, powerful objection: they self-undermine. For each formulation of the argument from disagreement, at least one of its premises casts doubt either on itself or on one of the other premises. On reflection, this shouldn’t be (...) surprising. These arguments are intended to support very strong metaphysical or epistemological conclusions about morality. They must therefore employ very strong metaphysical or epistemological premises. But, given the pervasiveness of disagreement in philosophy, especially about metaphysics and epistemology, very strong premises are virtually certain to be the subject of widespread, intractable disagreement—precisely the sort of disagreement that proponents of these arguments think undermine moral claims. Thus, these arguments undermine their own premises. If Chapter 2’s argument is sound, it provides realists with a single, unified strategy for responding to any existing or forthcoming arguments from disagreement. (shrink)

Theoretical arguments and empirical investigations indicate that a high proportion of published findings do not replicate and are likely false. The current position paper provides a broad perspective on scientific error, which may lead to replication failures. This broad perspective focuses on reform history and on opportunities for future reform. We organize our perspective along four main themes: institutional reform, methodological reform, statistical reform and publishing reform. For each theme, we illustrate potential errors by narrating the story of a fictional (...) researcher during the research cycle. We discuss future opportunities for reform. The resulting agenda provides a resource to usher in an era that is marked by a research culture that is less error-prone and a scientific publication landscape with fewer spurious findings.

Sometimes analogy researchers talk as if the freshness of an experience of analogy resides solely in seeing that something is like something else -- seeing that the atom is like a solar system, that heat is like flowing water, that paint brushes work like pumps, or that electricity is like a teeming crowd. But analogy is more than this. Analogy isn't just seeing that the atom is like a solar system; rather, it is seeing something new about the atom, an (...) observation enabled by 'looking' at atoms from the perspective of one's understanding of solar systems. The question for analogy researchers then is this: Where does this new knowledge about atoms come from? How can an analogy provide new knowledge and new understanding? (shrink)

Is it impossible for a person to do something intentionally without knowing that she is doing it? The phenomenon of self-deceived agency might seem to show otherwise. Here the agent is not lying, yet disavows a correct description of her intentional action. This disavowal might seem expressive of ignorance. However, I show that the self-deceived agent does know what she's doing. I argue that we should understand the factors that explain self-deception as masking rather than negating the practical knowledge characteristic (...) of intentional action. This masking takes roughly the following form: when we are deceiving ourselves about what we are intentionally doing, we don't think about our action because it's painful to do so. (shrink)

Years ago, when I was an undergraduate math major at the University of Wyoming, I came across an interesting book in our library. It was a book of counterexamples t o propositions in real analysis (the mathematics of the real numbers). Mathematicians work more or less like the rest of us. They consider propositions. If one seems to them to be plausibly true, then they set about to prove it, to establish the proposition as a theorem. Instead o f setting (...) out to prove propositions, the psychologists, neuroscientists, and other empirical types among us, set out to show that a proposition is supported by the data, and that it is the best such proposition so supported. The philosophers among us, when they are not causing trouble by arguing that AI is a dead end or that cognitive science can get along without representations, work pretty much like the mathematicians: we set out to prove certain propositions true on the basis of logic, first principles, plausible assumptions, and others' data. But, back to the book of real analysis counterexamples. If some mathematician happened t o think that some proposition about continuity, say, was plausibly true, he or she would then set out to prove it. If the proposition was in fact not a theorem, then a lot of precious time would be wasted trying to prove it. Wouldn't it be great to have a book that listed plausibly true propositions that were in fact not true, and listed with each such proposition a counterexample to it? Of course it would. (shrink)

People cannot contemplate a proposition without believing that proposition. A model of belief fixation is sketched and used to explain hitherto disparate, recalcitrant, and somewhat mysterious psychological phenomena and philosophical paradoxes. Toward this end I also contend that our intuitive understanding of the workings of introspection is mistaken. In particular, I argue that propositional attitudes are beyond the grasp of our introspective capacities. We learn about our beliefs from observing our behavior, not from introspecting our stock beliefs. -/- The model (...) of belief fixation offered in the dissertation poses a novel dilemma for theories of rationality. One might have thought that the ability to contemplate ideas while withholding assent is a necessary condition on rationality. In short, it seems that rational creatures shouldn‘t just form their beliefs based on whatever they happen to think. However, it seems that we are creatures that automatically and reflexively form our beliefs based on whatever propositions we happen to consider. Thus, either the rational requirement that states that we must have evidence for our beliefs must be jettisoned or we must accept the conclusion that we are necessarily irrational. (shrink)

Moorean arguments are a popular and powerful way to engage highly revisionary philosophical views, such as nihilism about motion, time, truth, consciousness, causation, and various kinds of skepticism (e.g., external world, other minds, inductive, global). They take, as a premise, a highly plausible first-order claim (e.g., cars move, I ate breakfast before lunch, it’s true that some fish have gills) and conclude from it the falsity of the highly revisionary philosophical thesis. Moorean arguments can be used against nihilists in ethics (...) (error theorists), too. Recently, error theorists have recognized Moorean arguments as a powerful challenge and have tried to meet it. They’ve argued that moral Moorean premises seem highly credible to us, but aren’t, by offering various debunking explanations. These explanations all appeal to higher-order evidence—evidence of error in our reasoning. I argue that drawing attention to higher-order evidence is a welcome contribution from error theorists, but that the higher-order evidence actually counts further against error theoretic arguments—including their debunking explanations—and further in favor of Moorean arguments and the commonsense views they support. Along the way I answer a few prominent objections to Moorean arguments: that they are objectionably question-begging, rely on categorizing some facts as “Moorean Facts”, and that reports of one’s credence in a proposition bears no interesting relation to that proposition’s credibility.

We examine a proposal for dealing with perhaps the chief difficulty facing holistic theories of meaning—meaning instability. The problem is that, given a robust holism, small changes in a representational system are likely to lead to meaning changes throughout the system. Consequently, different individuals are likely never to mean the same thing. Eric Lormand suggests that holists can avoid this problem—and even secure more stability than non-holists—by positing that symbols have multiple meanings. We argue that the proposal doesn't work, (...) however, since multiple meanings are unstable for much the same reason that single meanings are. (shrink)

The core of Zimmerman’s picture posits an inverse correlation between an action’s automaticity and belief’s role in the action’s execution. This proposal faces serious problems. First, high-attention, high-control actions don’t seem to heighten awareness of one’s beliefs. Second, low-attention, low-control actions are caused by the same states at play when executing high-attention, high-control actions, in which case there is no ontological difference in the states involved in these behaviors. Third, on Zimmerman’s view it is unclear what it is for a (...) state to be involved in behaviors at all, as the basic realist response—that beliefs cause behavior—is unavailable to a Zimmerman-style pragmatist. Lastly, if Zimmerman's view were right and low-level behaviors weren't caused by beliefs, then we should turn our attention to those states instead, as most of our behavior isn’t executed under conditions of high control and attention.

The notion of domain specificity plays a central role in some of the most important debates in cognitive science. Yet, despite the widespread reliance on domain specificity in recent theorizing in cognitive science, this notion remains elusive. Critics have claimed that the notion of domain specificity can't bear the theoretical weight that has been put on it and that it should be abandoned. Even its most steadfast proponents have highlighted puzzles and tensions that arise once one tries to go beyond (...) an initial intuitive sketch of what domain specificity involves. In this paper, we address these concerns head on by developing an account of what it means for a cognitive mechanism to be domain specific that overcomes the obstacles that have made domain specificity seem so problematic. We then apply this understanding of domain specificity to one of the key debates that it has figured prominently in—the rationalism-empiricism debate concerning the origins of cognitive traits—and introduce several related theoretical notions that work alongside domain specificity in helping to clarify what makes a view more (or less) rationalist. This example illustrates how the notion of domain specificity can, and should, continue to play a central role in ongoing debates in cognitive science. (shrink)

I find it interesting that AI researchers don't use concepts very often in their theorizing. No doubt they feel no pressure to. This is because most AI researchers do use representations which allow a system to chunk up its environment, and basically all we know about concepts is that they are representations which allow a system to chunk up its environment.

Mostly philosophers cause trouble. I know because on alternate Thursdays I am one -- and I live in a philosophy department where I watch all of them cause trouble. Everyone in artificial intelligence knows how much trouble philosophers can cause (and in particular, we know how much trouble one philosopher -- John Searle -- has caused). And, we know where they tend to cause it: in knowledge representation and the semantics of data structures. This essay is about a recent case (...) of this sort of thing. One of the take-home messages will be that AI ought to redouble its efforts t o understand concepts. (shrink)

For generations, philosophers of punishment have sought to revise or combine established theories of punishment in a way that could reconcile the utilitarian aims of punishment with the demands of deontological justice. Victor Tadros’ recent work addresses the same problem, but answers it w it h an entirely original theory of punishment based on the duties criminals acquire by committing their crimes. The unexpected appearance of a new rationale for punishment has already inspired a robust dialogue between Tadros and his (...) critics on many of the individual claims that, linked together, comprise his argument. This critique focuses instead on Tadros’ theory as a whole and the methodology he uses to support it. It proposes that Tadros’ argumentative strategy can’t justify his rationale by virtue of (1) the extent and complexity of the moral reasoning he invokes, (2) the counter-intuitive results his theory produces in an array of specific cases, and (3) the superiority of a negative-retributivist account in which moral reasoning and intuitive judgments, and the principles and applications that f low from each, are coherent and mutually supportive. Victor Tadros responds to these arguments in an essay following this critique. (shrink)

It's unclear what narrow content is interpersonally shared for concepts that don't originate from core cognition yet are still definitionally and interpretationally primitive. A primary concern is that for these concepts, one cannot draw a principled distinction between inferences that are content determining and those that aren't. The lack of a principled distinction imperils an account of interpersonally shared concepts.

Conceptual analysis is undergoing a revival in philosophy, and much of the credit goes to Frank Jackson. Jackson argues that conceptual analysis is needed as an integral component of so-called serious metaphysics and that it also does explanatory work in accounting for such phenomena as categorization, meaning change, communication, and linguistic understanding. He even goes so far as to argue that opponents of conceptual analysis are implicitly committed to it in practice. We show that he is wrong on all of (...) these points and that his case for conceptual analysis doesn't succeed. At the same time, we argue that the sorts of intuitions that figure in conceptual analysis may still have a significant role to play in philosophy. So naturalists needn't disregard intuitions altogether. (shrink)

People sometimes knowingly undermine the achievement of their own goals by, e.g., playing the lottery or borrowing from loan sharks. Are these agents acting irrationally? The standard answer is “yes.” But, in a recent award-winning paper, Jennifer Morton argues “no.” On her view, the norms of practical reasoning an agent ought to follow depend on that agent’s resource context (roughly, how rich or poor they are). If Morton is correct, the orthodox view that the same norms of practical rationality apply (...) to all agents needs revision. I argue that Morton’s arguments fail on empirical and philosophical grounds. What’s at stake? If Morton is correct, poverty relief agencies ought to re-design their incentives so resource-scarce agents can rationally respond to them. If I’m correct, resource-scarce agents do act irrationally in the cases under discussion, and we shouldn’t be shy about saying so. Instead of declaring them rational, we should try to understand the causes of their irrational behavior and help them better succeed by their own lights. (shrink)

Objections to AI and computational cognitive science are myriad. Accordingly, there are many different reasons for these attacks. But all of them come down to one simple observation: humans seem a lot smarter that computers -- not just smarter as in Einstein was smarter than I, or I am smarter than a chimpanzee, but more like I am smarter than a pencil sharpener. To many, computation seems like the wrong paradigm for studying the mind. (Actually, I think there are deeper (...) and darker reasons why AI, especially, is so often the brunt of polemics, see Dietrich, 2000.) But the truth is this: AI is making exciting progress, and will one day make a robot as intelligent as a person; indeed the robot will be conscious. And all this is because of another truth: the computational paradigm is the best thing to come down the pike since the wheel. (shrink)

The Language of Thought Hypothesis is often taken to have the fatal flaw that it generates an explanatory regress. The language of thought is invoked to explain certain features of natural language (e.g., that it is learned, understood, and is meaningful), but, according to the regress argument, the language of thought itself has these same features and hence no explanatory progress has been made. We argue that such arguments rely on the tacit assumption that the entire motivation for the language (...) of thought consists in explaining the explanandum that allegedly generates the regress. But this tacit assumption is simply false. The Language of Thought Hypothesis is a cogent view and one with considerable explanatory advantages. (shrink)

Textual entailment is a relationship that obtains between fragments of text when one fragment in some sense implies the other fragment. The automation of textual entailment recognition supports a wide variety of text-based tasks, including information retrieval, information extraction, question answering, text summarization, and machine translation. Much ingenuity has been devoted to developing algorithms for identifying textual entailments, but relatively little to saying what textual entailment actually is. This article is a review of the logical and philosophical issues involved in (...) providing an adequate definition of textual entailment. We show that many natural definitions of textual entailment are refuted by counterexamples, including the most widely cited definition of Dagan et al. We then articulate and defend the following revised definition: T textually entails H = df typically, a human reading T would be justified in inferring the proposition expressed by H from the proposition expressed by T. We also show that textual entailment is context-sensitive, nontransitive, and nonmonotonic. (shrink)

When Charles Darwin died in April, 1882, he left behind a world changed forever. Because of his writings, most notably, of course, The Origin of Species, by 1882, evolution was an almost universally acknowledged fact. What remained in dispute, however, was how evolution occurred. So because of Darwin’s work, everyone accepted that new species emerge over time, yet few agreed with him that it was natural selection that powered the change, as Darwin hypothesized. Chalmers’ book, The Conscious Mind , reminds (...) me of The Origin of Species . I have talked t o many people about The Conscious Mind and watched many philosophy students read it, and after they are done, they all take consciousness more seriously than they did before and they are all struck by its deep mystery, yet few accept Chalmers’ specific theory of consciousness and his explanation of its odd nature.

Computationalism treats minds as computations. It hasn't explained how our quite similar sensory circuits encode our quite different qualia, nor how these circuits encode the binding of the different qualia into unifi ed perceptions. But there is growing evidence that qualia and binding come from neural electrochemical substances such as sensory detectors and the strong continuous electromagnetic field they create. Qualia may thus be neural substances, not neural computations (though computations may still help modulate qualia). This neuroelectrical view not only (...) avoids computationalism's empirical issues but also its problematic metaphysics. (shrink)

Many philosophers reject the Language of Thought Hypothesis (LOT) on the grounds that is leads to an explanatory regress problem. According to this line of argument, LOT is invoked to explain certain features of natural language, but the language of thought has the very same features and consequently no explanatory progress has been made. In an earlier paper (“Regress Arguments against the Language of Thought”, Analysis 57.1), we argued that this regress argument doesn’t work and that even proponents of LOT (...) have given the regress argument too much credit. In this paper, we extend our critique of the regress argument against LOT by responding to J. Knowles’s commentary of our earlier paper (in “The Language of Thought and Natural Language Understanding”, Analysis 58.4). (shrink)

Some of the questions I attempt to deal with are as follows: What does it mean to mean something? How does meaning happen? What do we really mean when we say that something means something? Can there be meaning without a mind? Is meaning something fixed or is it more like an unstable flux? How do concepts affect or determine the way we perceive the world? Aren’t metaphor, metonymy and other figures of speech very natural occurrences when meaning is understood (...) more as an unstable flux than as something fixed and permanent? Do innate ideas or concepts exist? Or is it rather that we have innate ways of creating concepts? How do we (re) create concepts? How do concepts relate to meaning? How do concepts integrate and relate so as to create more complex meanings at higher levels? And how do they relate to grammar? Is grammar a set of rules or is it rather a set of conventions? How does grammar interact with the structures of our concepts? (shrink)

Fiona Cowie's book What's Within: Nativism Reconsidered offers an important critical assessment of nativist views of the mind. She provides an account of what nativism consists in, and discusses prominent nativist views of concept acquisition and language acquisition. In the latter case, she also offers an empiricist alternative to Chomskyan nativist accounts, and claims that the main arguments for an innate language faculty—one that embodies Universal Grammar—don't work. We provide an overview of her position, focusing mostly on her views about (...) natural language, and argue that she has underestimated the power the poverty of the stimulus argument and consequently has underestimated the advantages of nativist models of language acquisition.

What happens when a psychologist who’s spent the last 30 years developing a method of introspective sampling and a philosopher whose central research project is casting skeptical doubt on the accuracy of introspection write a book together? The result, Hurlburt & Schwitzgebel’s thought-provoking Describing Inner Experience?, is both encouraging and disheartening. Encouraging, because the book is a fine example of fruitful and open-minded interdisciplinary engagement; disheartening, because it makes clear just how difficult it is to justify the accuracy of introspective (...) methods in psychology and philosophy. And since debates in consciousness studies largely turn on fine points of introspective detail, this is no minor methodological stumbling block. (shrink)

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

Daoism and Environmental Philosophy explores ethics and the philosophy of nature in the Daodejing, the Zhuangzi, and related texts to elucidate their potential significance in our contemporary environmental crisis. This book traces early Daoist depictions of practices of embodied emptying and forgetting and communicative strategies of undoing the fixations of words, things, and the embodied self. These are aspects of an ethics of embracing plainness and simplicity, nourishing the asymmetrically differentiated yet shared elemental body of life of the myriad things, (...) and being responsively attuned in encountering and responding to things. These critical and transformative dimensions of early Daoism provide exemplary models and insights for cultivating a more expansive ecological ethos, environmental culture of nature, and progressive political ecology. This work will be of interest to students and scholars interested in philosophy, environmental ethics and philosophy, religious studies, and intellectual history. (shrink)

In this wide-ranging and authoritative volume, leading scholars engage with the philosophy and writings of Wilhelm Dilthey, a key figure in nineteenth-century thought. Their chapters cover his innovative philosophical strategies and explore how they can be understood in relation to their historical situation, as well as presenting incisive interpretations of Dilthey's arguments, including their development, their content, and their influence on later thought. A key focus is on how Dilthey's work remains relevant to current debates around art and literature, the (...) biographical and autobiographical self, knowledge, language, science, culture, history, society, and psychology and the embodied mind. The volume will be important for researchers in hermeneutics, aesthetics, practical philosophy, and the history of German philosophy, providing a valuable introduction to Dilthey's work as well as detailed critical analysis of its ongoing significance.

One of the deepest and longest-lasting debates in ethics concerns a version of the Euthyphro question: are choiceworthy things choiceworthy because agents have certain attitudes toward them or are they choiceworthy independent of any agents’ attitudes? Reasons internalists, such as Bernard Williams, Michael Smith, Mark Schroeder, Sharon Street, Kate Manne, Julia Markovits, and David Sobel answer in the first way. They think that all of an agent’s normative reasons for action are grounded in facts about that agent’s pro-attitudes (e.g., her (...) desires, valuing states, normative judgments). According to the most popular brand of internalism, idealizing internalism, an agent’s reasons are grounded, not in her actual pro-attitudes, but rather in what her pro-attitudes would be in suitably idealized conditions. Idealizing internalists presuppose that, for any agent with an irrational set of attitudes, there is one uniquely rational set that that agent would have if she were to undergo the relevant idealizing process. I argue that this assumption is false and that it raises two puzzles for idealizing internalism: one about the existence of practical reasons and another about their normative weight. I argue that idealizing internalists have an adequate solution to the first puzzle but not the second. Indeed, when they try to solve the second puzzle, they confront a dilemma. This second puzzle and the associated dilemma thus constitutes a powerful, but so far unnoticed, difficulty for idealizing internalism. (shrink)

Foundational theories of mental content seek to identify the conditions under which a mental representation expresses, in the mind of a particular thinker, a particular content. Normativists endorse the following general sort of foundational theory of mental content: A mental representation r expresses concept C for agent S just in case S ought to use r in conformity with some particular pattern of use associated with C. In response to Normativist theories of content, Kathrin Glüer-Pagin and Åsa Wikforss propose a (...) dilemma, alleging that Normativism either entails a vicious regress or falls prey to a charge of idleness. In this paper, I respond to this argument. I argue that Normativism can avoid the commitments that generate the regress and does not propose the sort of explanation required to charge that its explanation has been shown to be problematically idle. The regress-generating commitment to be avoided is, roughly, that tokened, contentful mental states are the product of rule-following. The explanatory task Normativists should disavow is that of explaining how it is that beliefs and other contentful mental states are produced. I argue that Normativism, properly understood as a theory of content, does not provide this kind of psychological explanation, and therefore does not entail that such explanations are to be given in terms of rule-following. If this is correct, Normativism is not the proper target of the dilemma offered by Glüer-Pagin and Wikforss. Understanding why one might construe Normativism in the way Glüer-Pagin and Wikforss must, and how, properly understood, it avoids their dilemma, can help us to appreciate the attractiveness of a genuinely normative theory of content and the importance of paying careful attention to the sort of normativity involved in norm-based theories of content.

Philosophy and Phenomenological Research, EarlyView.

In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely the (...) same calculated quantities such as their energies, dipole moments etc. The only means through which the difference between the isomers can be recovered is to build their structures into the quantum mechanical calculations, something that is carried out by the application of the Born-Oppenheimer approximation. Consequently, it has been argued by many authors that molecular structure is written in ‘by hand’ rather than derived. Robin Hendry is one such author, but he goes a great deal further by proposing that this situation implies the existence of emergence and downward causation. In the current article I argue that there are alternative explanations which render emergence and downward causation redundant. Such an alternative lies in the notion of quantum decoherence and the appeal to work in the foundations of physics, which posits that the various isomers exist as a superposition until their wavefunctions are collapsed either by observation or by interacting with their environment. Hendry also alludes to a debate among chemists as to whether chemical bonds are real or not, in the sense of directional connections between two or more nuclei in any given molecule. I reject this view and propose that the structural and energetic views of chemical bonding, that have been discussed by some philosophers of chemistry including Hendry, do not refer to any essential ontological differences. I agree that chemists view bonding in a more realistic fashion and may consider bonds to be in some senses real, while physicists may consider bonding in more abstract energetic terms. However, I do not believe that such differences in scientific practice and attitudes should be considered to offer a window as to the ontological status of bonding or whether bonding is real. Finally, I discuss the kinetic energy school of chemical bonding which would seem to challenge any notion of bonds as directional entities, since bonding is no longer regarded as being primarily due to the build-up of electron density between nuclei.

We propose capability as a universal or type intermediate between function and disposition. A capability is, broadly speaking, a disposition that is of a type whose instances can be evaluated on the basis of how well they are realized. A function, on the view we are proposing, is a capability the possession of which is the rationale for the existence of its bearer. To say for example that a water pump has the function to pump water is to say that (...) the pump exists because something was needed that would pump water. A water pump may have many capabilities, including: to be weatherproof, to run without lubricant, to be transportable, and so forth. But its function is to pump water. We focus here on capabilities possessed by humans – such as piano playing or language using – and we explore the relation between capabilities of these sorts and structures in the brain. (shrink)

This chapter explores Nagel’s polemics. It shows these have a two-fold character: (i) to defend liberal civilization against all kinds of enemies. And (ii) to defend what he calls ‘contextual naturalism.’ And the chapter shows that (i-ii) reinforce each other and undermine alternative political and philosophical programs. The chapter’s argument responds to an influential argument by George Reisch that Nagel’s professional stance represents a kind of disciplinary retreat from politics. In order to respond to Reisch the relationship between Nagel’s philosophy (...) of science and his politics is explored and this chapter shows how both are anchored in what Nagel once called his ‘contextual naturalism’—a metaphysics that resists imposing the unity of the world and treats all entities as embedded in a wider network of entities. Part of the argument traces out how Nagel’s views on responsible speech and professionalism reflect a distinct understanding of the political role of philosophers of science. (shrink)

Aristotle's account of external goods in Nicomachean Ethics I 8-12 is often thought to amend his narrow claim that happiness is virtuous activity. I argue, to the contrary, that on Aristotle's account, external goods are necessary for happiness only because they are necessary for virtuous activity. My case innovates in three main respects: I offer a new map of EN I 8-12; I identify two mechanisms to explain why virtuous activity requires external goods, including a psychological need for external goods; (...) and I show the relevance of Aristotle's distinction between wishing and choosing. On the view I attribute to Aristotle, our capacity to choose virtuously requires, first, that we wish for external goods (because virtue requires the right attitudes of evaluation) and, second, that these wishes are generally fulfilled (because the social consequences and psychological pain of unfulfilled wishes undermine our opportunity to act virtuously and to take pleasure in acting virtuously). I close with discussion of how Aristotelians should defend this approach. (shrink)

Plato argues that four political arts—politics, kingship, slaveholding, and household-management—are the same. His argument, which prompted Aristotle’s reply in Politics I, has been universally panned. The problem is that the argument clearly identifies household-management with slaveholding, and household-management with politics, but does not fully identify kingship with any of the others. I consider and reject three ways of saving the argument, and argue for a fourth. On my view, Plato assumes that politics is identical with kingship, just as he does (...) elsewhere, but he begs no questions because the point of his argument is to identify the public arts of politics and kingship with the private arts of household-management and slaveholding. He does this successfully by answering three reasons why one might distinguish the private from the public arts. His argument leaves room for Aristotle to propose other reasons. One of them—involving differences among men and women and slaves—is unfortunate, but another is more promising. The Aristotelian can assume that political expertise is a matter of know-how gathered by experience of the particular actions which differ in the public and private arts. But Plato might well be right to reject this, and to insist that the essential difference between the expert and non-expert—the dividing line between good and bad rule—is not in experience but in their grasp of their goals.

Here I consider the two most venerated arguments about the existence of God: the Ontological Argument and the Argument from Evil. The Ontological Argument purports to show that God’s nature guarantees that God exists. The Argument from Evil purports to show that God’s nature, combined with some plausible facts about the way the world is, guarantees (or is very compelling grounds for thinking) that God does not exist. Obviously, both arguments cannot be sound. But I argue here that they are (...) both unsound for the very same reason. (shrink)
