Conway Morris argues against Stephen Jay Gould's argument that the history of life is radically contingent by describing the abundance of convergences, wherein different lineages starting in different states, arrive at the same adaptations. A standard example is the evolution of the camera eye. This review assesses the validity of Conway Morris' argument.

1. EXPLICATING THE CONCEPT OF REFLECTION (under review) -/- To understand how ‘reflection’ is used, I consider ordinary, philosophical, and scientific discourse. I find that ‘reflection’ seems to refer to reasoning that is deliberate and conscious, but not necessarily self-conscious. Then I offer an empirical explication of reflection’s conscious and deliberate features. These explications not only help explain how reflection can be detected; they also distinguish reflection from nearby concepts such as ruminative and reformative reasoning. After this, I find that (...) reflection is not obviously limited to only practical or only theoretical reasoning. The chapter ends with reasons to prefer ‘unreflective’ and ‘reflective’ to dual process theorists’ labels about systems or types. -/- 2. BOUNDED REFLECTIVISM & EPISTEMIC IDENTITY (in Metaphilosophy) -/- Reflection features centrally in philosophy (e.g., Korsgaard, 1996; Rawls, 1971; Sosa, 1991) and psychology (e.g., Pennycook, 2018). Bounded reflectivism is an empirically adequate model of reflection that explains reflection’s capacity to either help or hinder reasoning—e.g., reflective equilibrium vs. reflective polarization (e.g., Kahan et al., 2017). One innovation of the model is epistemic identity: an identity that involves particular beliefs—e.g., religious and political identities. When we feel that our epistemic identity is threatened, we can reflectively defend its beliefs rather than update our beliefs according to the best arguments and evidence. The solution, I argue, is not to suppress epistemic identity but embrace it by appealing to shared, superordinate epistemic identities. -/- 3. ALL MEASURES ARE NOT CREATED EQUAL (under review) -/- A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost? “10 cents” comes to most people’s minds immediately. However, upon reflection, we can realize that “5 cents” is the correct answer. There are many reflection tests. Each has its limitations. Some reflection tests are mathematical—like the bat-and-ball problem (e.g., Frederick, 2005) and others are logical (e.g., Janis & Frick, 1943). So there are concerns that reflection tests track logical and mathematical competence rather than reflection per se. Also, some psychologists assume a priori that correct answers are reflective and lured answers are unreflective. New evidence raises additional concerns about the plausibility of these assumptions. I argue that think aloud protocols (Ericsson & Simon, 1998) and process dissociation (Jacoby, 1991) can assuage some of these concerns. -/- 4. GREAT MINDS DO NOT THINK ALIKE (in Review of Philosophy and Psychology) -/- Two large studies (N = 1299), one pre-registered, found that many correlations between reflection and philosophical beliefs among non-philosophers replicated among philosophers. For example, less reflective philosophers preferred theism to atheism and utilitarian rather than deontological responses to the trolley problem (Hannikainen & Cova, in prep.; Pennycook et al., 2016; Reynolds, Byrd, & Conway, forthcoming). However, philosophical judgments were sometimes better predicted by factors like education, gender, and personality than by reflection test performance. So although some relationships between reflection and philosophy were robust, there is more to the link between reflection and philosophy. Normative implications are also discussed—e.g., how we can infer the quality of philosophical views from their correlations with reflective or unreflective reasoning. -/- 5. WHAT WE CAN (AND CAN’T) INFER ABOUT IMPLICIT BIAS (in Synthese) -/- Contrary to some philosophers and psychologists, I argue that implicit bias is probably associative. However, I also argue that debiasing is not thereby entirely unconscious and involuntary. Indeed, strong evidence suggests that reflection can change implicitly biased behavior—e.g., conscious and deliberate counterconditioning. This has implications for the science and morality of implicit bias—e.g., evidence suggests that we can reform biases; so. intuitively, we can be responsible for biases. (shrink)

“Another Nietzsche’s On the Genealogy of Morality?” one might be excused for asking at the sight of Simon May’s new collection. This volume has to contend for shelf space with homonymic monographs by Lawrence Hatab (2008) and David Owen (2007), as well as Daniel Conway’s (2008) Nietzsche’s On the Genealogy of Morals, a compilation of the same name edited by Christa Acampora (2006), and Brian Leiter’s Nietzsche on Morality (2002). Add to this that Hatab contributes to May’s collection, (...) Owen and Conway contribute to Acampora’s, and Christine Swanton contributes to both, and the question of redundancy becomes even more pressing. Is Nietzsche’s Genealogy – whether of morality or morals – sufficiently rich, difficult, and interesting to merit such a hubbub of scholarly voices, and, if it is, does the attention paid in May’s new volume significantly advance our understanding of it? The answer to both questions is an unequivocal “Yes.”. (shrink)

The acceptance of causal closure has had a profoundly limiting effect on the philosophical treatment of sui generis mental causation in recent decades. Philosophical treatments of special divine action have been likewise hampered by a widespread commitment to closure. If fundamental reality is as closure tells us it is, then nonphysical minds—human and divine— are either causally impotent or redundant. In this paper, I reject this limitation as baseless. Specifically, I will show how Hempel’s dilemma poses a far greater challenge (...) when applied to a causal closure principle than it did to the task of defining physicalism. Reponses to the dilemma can be used to disambiguate closure, but not without significant cost. In light of Hempel’s dilemma, there is no conception of closure that can do all of the following: rule out sui generis mental causation, have a reasonable chance of being true, and avoid problematic circularity. At the end of the day, I maintain that closure, properly understood, is, or ought to be, just one methodological stance among many. If this is correct, it is a stance that a theist can freely reject.

In 2022, at an interdisciplinary conference on Creation and the Imago Dei, Biola psychologist Liz Hall posed a powerful challenge to the philosophers and theologians in the room. In the face of the “already and not yet” nature of Christian theology, she put forth the need for a “theology of tension.” Over and over again, while reading Biblical Philosophy, I was reminded of this challenge. The features Johnson puts forth as emblematic of Hebraic Philosophy can help in this respect, in (...) two clear ways: First, retrospectively, Johnson’s categories are useful for diagnosing both the philosophical missteps targeted by critiques of theodicy and the features held in common by some of the more successful accounts. Second, going forward, the convictions and modes of argument central to Hebraic philosophy may help guide future philosophical responses to suffering. In general, I believe that the philosophical problems related to suffering are especially well-suited to responses that are pixelated, networked, mysterianist, creationist, transdemographic, and ritualist. Perhaps Hebraic philosophy can succeed where Hellenist philosophy has struggled: in addressing the tension that arises from the experience of suffering in a world governed by a loving, providential, sovereign God. While I am largely in favor of Johnson’s Hebraic philosophy, I will conclude by breaking from his view in one important respect. Johnson presents the Biblical view as substantially contrasting with the correspondence theory affirmed by many contemporary philosophers. I will end by pushing back on this claim. On Johnson’s own account, the Hebraic notion of truth is determined with reference to the divinely designed order. I propose that we understand the Hebraic notion of truth as degrees of correspondence to this divinely ordered, absolute reality. (shrink)

Erik Wielenberg recently invoked the parent-child analogy in an argument against Christian theism. The argument relies on the claim that a loving parent would never allow her child to feel abandoned in the midst of what feels like gratuitous suffering. In this paper, I offer three clear counterexamples to Wielenberg’s central premise. At the same time, a successful counterexample does not a robust theology of suffering make. To that end, and with a careful eye towards anti-theodical concerns, I defend the (...) need for a more proactive Christian philosophical examination of the role of suffering in a meaningful life.

ABSTRACT In Consciousness and Fundamental Reality, Philip Goff argues that the case against physicalist views of consciousness turns on ‘Phenomenal Transparency’, roughly the thesis that phenomenal concepts reveal the essential nature of phenomenal properties. This paper considers the argument that Goff offers for Phenomenal Transparency. The key premise is that our introspective judgments about current conscious experience are ‘Super Justified’, in that these judgments enjoy an epistemic status comparable to that of simple mathematical judgments, and a better epistemic status than (...) run of the mill perceptual judgments. After presenting the key ideas in the ‘Super Justification Argument’, I distinguish two Super Justification theses, which vary according to the kind of introspective judgments that they take to be Super Justified. I argue that Goff’s case requires ‘Strong Super Justification’, according to which a wide range of introspective judgments about conscious experience are Super Justified. Unfortunately, it turns out that Strong Super Justification is implausible and not well-supported by examples. In contrast, a weaker Super Justification thesis does not require anything like Phenomenal Transparency and, indeed, can be explained by physicalistic accounts of phenomenal concepts. (shrink)

Jaegwon Kim argued that nonreductive physicalism faces the “exclusion problem” for higher-level causation, mental causation in particular. Roughly, the charge is that given the presumptive ubiquity of physical causation, there cannot be irreducible mental causes for physical effects. Since there are mental causes, Kim concluded that nonreductive physicalism should be rejected in favor of a more reductionist alternative according to which mental causes are just physical causes differently described. But why should mental causes be “excluded” in this way? Unfortunately, Kim (...) had less to say about this than one might expect. After reviewing some of Kim’s proposals, I suggest that the exclusion problem should be premised on nothing more or less than Occamist, simplicity-based considerations. I apply this conception of the exclusion problem to some prominent responses to Kim’s critique of nonreductive physicalism and argue that this conception mandates reconsidering the success of these responses.

According to phenomenal transparency, phenomenal concepts are transparent where a transparent concept is one that reveals the nature of that to which it refers. What is the connection between phenomenal transparency and our concept of a subject of experience? This paper focuses on a recent argument, due to Philip Goff, for thinking that phenomenal transparency entails transparency about subjecthood. The argument is premissed on the idea that subjecthood is related to specific phenomenal properties as a determinable of more specific determinates. (...) I argue that the argument fails, which opens the door for one to endorse phenomenal transparency while denying transparency about the concept of a subject of experience. I draw out the consequences of this for certain versions of the combination problem for panpsychist metaphysics and moreover argue that rejecting the transparency of subjecthood does not undermine anti-physicalist arguments premissed on considerations relating to phenomenal transparency.

In his recent The Parmenidean Ascent, Michael Della Rocca develops a regress-theoretic case, reminiscent of F.H. Bradley’s famous argument in Appearance and Reality, against the intelligibility of relations and in favor of a monistic conception of reality. I argue that Della Rocca illicitly supposes that “internal” relations – in one sense of that word – lead to a “chain” regress, a regress of relations relating relations and relata. In contrast, I contend that if “internal” or grounded relations lead to a (...) regress at all, it is a kind of “fission” regress within the relata themselves, and that a chain regress for relations only arises, if at all, for so-called “external” relations, relations not grounded in their relata. In this way, I contend that Della Rocca pursues a regress for so-called “internal” or grounded relations that only arises, if at all, for so-called “external” relations, relations not grounded in their relata. I compare Della Rocca’s case against relations with Bradley’s reasoning in Appearance and Reality, and suggest in this context that Bradley may, perhaps, have the upper hand. (shrink)

This paper discusses and evaluates a recent argument for the conclusion that an attractive variety of Russellian monism ought to be regarded as a form of physicalism. According to this line of thought, if the Russellian’s “inscrutable” properties are held to ground not only experience, but also the physical structure of the world—and in this sense are not “experience-specific”—they thereby have an unproblematic place in physicalist metaphysics. I argue, in contrast, that there can be a sense in which the Russellian’s (...) inscrutables are experience-specific in a way that a physicalist probably ought to find objectionable, even if they play some role other than grounding experience. This will be the case, I argue, if certain worlds are taken to be possible, as they sometimes have: worlds of “bare structure” and worlds with what might be called “swapped inscrutables”. In this way, I claim that accepting certain possibilities has consequences for how one should understand the nature of the Russellian’s inscrutables and the place they have in physicalist metaphysics.

In Morris I presented in outline a new interpretation of the famous ‘substance argument’ in Wittgenstein’s Tractatus. The account I presented there gave a distinctive view of Wittgenstein’s main concerns in the argument, but did not explain in detail how the argument works: how its steps are to be found in the text, and how it concludes. I remain convinced that the interpretation I proposed correctly identifies the main concerns which lie behind the argument. I return to the argument (...) here in order to elaborate in fuller detail the relation between those concerns and the actual course of the text. (shrink)

The relationship of part to whole is one of the most fundamental there is; this is the first and only full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology.

The concept of truthmaking, the idea that when a statement is true, there is typically something about the world in virtue of which it is true, has garnered much interest in recent metaphysics. Often, the motivation has been the thought that truthmaking can provide a new perspective on an important issue. This paper evaluates the claim that truthmaking can play a substantive role in defining an unproblematic notion of emergence. For despite playing an important role in philosophical discourse over the (...) past 100 years, it has often been thought that there is something mysterious about the notion of emergence. It has recently been argued, however, that once emergent properties are characterized as those that, while “ontologically dependent” are yet needed as truthmakers emergence and emergent properties prove unproblematic. In response, I argue that there is reason to doubt that truthmaking can play an important role in formulating an unproblematic yet recognizable notion of emergence. I argue that it is consistent with truthmaking being unable to play a substantive role in emergentism that truthmaking can play a more significant role in characterizing an attractive middle ground between reductive and nonreductive physicalism.

In this dissertation, I examine the implications of the problem of mental causation and what David Chalmers has dubbed the “ hard problem of consciousness” for competing accounts of the mind. I begin, in Chapter One, with a critical analysis of Jaegwon Kim’s Physicalism, or Something Near Enough. (2005) There, I maintain that Kim’s ontology cannot adequately address both the problem of mental causation and the “ hard problem of consciousness.” In Chapter Two, I examine the causal pairing problem for (...) substance dualism. I demonstrate both that the substance dualist can respond to the argument at no great cost, and that the pairing problem applies, with equal force, to the irreducible qualia posited on Kim’s account. Chapters Three and Four are devoted to what I take to be the central argument against any kind of dualism: the causal exclusion argument. In Chapter Three, I examine dualistic responses to the exclusion argument that grant the causal closure of the physical world. I note that these responses, though technically adequate, are nevertheless theoretically unpalatable. In addition to requiring the dualist to adopt unconventional attitudes towards causation, responses of this variety also have the unfortunate result of rendering libertarian freedom impossible. Finally, in Chapter Four, I turn my attention to the question of causal closure. I maintain that the causal closure of the physical world, though widely affirmed, is nevertheless extraordinarily difficult to support. In light of Hempel’s Dilemma, causal closure is either false, compatible with dualistic interaction, or unacceptably stipulative. There is, I maintain, no causal closure principle up to the tasks required by the causal exclusion argument. For that reason, I conclude that the dualist ought not to worry about causal closure.

Interested in art, we tend to be interested in works of art. We seem to encounter works of art all the time, and—setting aside certain relatively abstruse problems in ontology—we seem to have little difficulty in recognizing them for what they are. That there are works of art seems obvious and unproblematic. Quite so, I think. But reflection on what has to be the case if there are to be works of art shows that some quite demanding conditions have to (...) be met. Some will find those conditions too demanding: if I am right, that means that they should not admit that there are any works of art, and they will have to give some other account of what might be involved when we think we are dealing with a work of art. For myself, I think the conditions are not too demanding: their interest comes in what they show us about the nature of artistic ‘media’, and about what is involved in being a great artist. (shrink)

Which political principles should govern global politics? In his new book, Simon Caney engages with the work of philosophers, political theorists, and international relations scholars in order to examine some of the most pressing global issues of our time. Are there universal civil, political, and economic human rights? Should there be a system of supra- state institutions? Can humanitarian intervention be justified?

This paper develops an information-sensitive theory of the semantics and probability of conditionals and statements involving epistemic modals. The theory validates a number of principles linking probability and modality, including the principle that the probability of a conditional If A, then C equals the probability of C, updated with A. The theory avoids so-called triviality results, which are standardly taken to show that principles of this sort cannot be validated. To achieve this, we deny that rational agents update their credences (...) via conditionalization. We offer a new rule of update, Hyperconditionalization, which agrees with Conditionalization whenever nonmodal statements are at stake but differs for modal and conditional sentences. (shrink)

It is generally assumed that existing artificial systems are not phenomenally conscious, and that the construction of phenomenally conscious artificial systems would require significant technological progress if it is possible at all. We challenge this assumption by arguing that if Global Workspace Theory (GWT) — a leading scientific theory of phenomenal consciousness — is correct, then instances of one widely implemented AI architecture, the artificial language agent, might easily be made phenomenally conscious if they are not already. Along the way, (...) we articulate an explicit methodology for thinking about how to apply scientific theories of consciousness to artificial systems and employ this methodology to arrive at a set of necessary and sufficient conditions for phenomenal consciousness according to GWT.

In this dissertation I examine the ontological and systematic basis of Hegel’s social and political philosophy. I argue that the structures of the will, discussed in paragraphs five through seven of the Philosophy of Right, present the key for understanding the goal and the argumentative structure of that work. Hegel characterizes the will in terms of the oppositions between the universal and the particular, the infinite and the finite, and the indeterminate and the determinate. Ultimately, he argues that we must (...) grasp the will as the unity of these oppositional moments. The Philosophy of Right presents an extended attempt to grasp this unity. -/- In order to central problem presented by the structure of the will, I argue that we must first recognize the will as the highest instantiation of the more general structures that constitute the notion. On my interpretation, the term ‘notion’ designates Hegel’s doctrine of substance. More specifically, this term presents his conception of substance in terms of categories normally associated with human subjectivity, in terms of representation and purposive action. -/- The will presents the highest or truest instantiation of the notion. Various notions can be ranked along a spectrum in accordance with their degree of success at resolving the basic problem facing all objects – namely the problem of integrating or essentially relating identity and difference through self-constituting activity. The unification of identity and difference presents the central problem or paradox of Hegel’s philosophy. It is a paradox that takes many forms. In this dissertation, I show how change, the structure of judgment, and the nature of the object all exhibit this paradox. I also show how Hegel’s doctrine of the notion develops as a direct response to this paradox. Additionally, I argue that Hegel’s account of the structure of the will – as the unity of the universal and the particular, the unity of the infinite and the finite, and the unity of the indeterminate and the determinate – presents the highest manifestation of the paradox that arises when we seek to explain the unity of identity and difference.

This paper examines the question of whether Large Language Models (LLMs) like ChatGPT possess minds, focusing specifically on whether they have a genuine folk psychology encompassing beliefs, desires, and intentions. We approach this question by investigating two key aspects: internal representations and dispositions to act. First, we survey various philosophical theories of representation, including informational, causal, structural, and teleosemantic accounts, arguing that LLMs satisfy key conditions proposed by each. We draw on recent interpretability research in machine learning to support these (...) claims. Second, we explore whether LLMs exhibit robust dispositions to perform actions, a necessary component of folk psychology. We consider two prominent philosophical traditions, interpretationism and representationalism, to assess LLM action dispositions. While we find evidence suggesting LLMs may satisfy some criteria for having a mind, particularly in game-theoretic environments, we conclude that the data remains inconclusive. Additionally, we reply to several skeptical challenges to LLM folk psychology, including issues of sensory grounding, the "stochastic parrots" argument, and concerns about memorization. Our paper has three main upshots. First, LLMs do have robust internal representations. Second, there is an open question to answer about whether LLMs have robust action dispositions. Third, existing skeptical challenges to LLM representation do not survive philosophical scrutiny. (shrink)

LLMs have dramatically improved in capabilities in recent years. This raises the question of whether LLMs could become genuine agents with beliefs and desires. This paper demonstrates an in principle limit to LLM agency, based on their architecture. LLMs are next word predictors: given a string of text, they calculate the probability that various words can come next. LLMs produce outputs that reflect these probabilities. I show that next word predictors are exploitable. If LLMs are prompted to make probabilistic predictions (...) about the world, these predictions are guaranteed to be incoherent, and so Dutch bookable. If LLMs are prompted to make choices over actions, their preferences are guaranteed to be intransitive, and so money pumpable. In short, the problem is that selecting an action based on its potential value is structurally different then selecting the description of an action that is most likely given a prompt: probability cannot be forced into the shape of expected value. The in principle exploitability of LLMs raises doubts about how agential they can become. This exploitability also offers an opportunity for humanity to safely control such AI systems. (shrink)

This paper explores the principle that knowledge is fragile, in that whenever S knows that S doesn’t know that S knows that p, S thereby fails to know p. Fragility is motivated by the infelicity of dubious assertions, utterances which assert p while acknowledging higher-order ignorance whether p. Fragility is interestingly weaker than KK, the principle that if S knows p, then S knows that S knows p. Existing theories of knowledge which deny KK by accepting a Margin for Error (...) principle can be conservatively extended with Fragility. (shrink)

Existing indexing systems used to arrange philosophical works have been shown to misrepresent the discipline in ways that reflect and perpetuate exclusionary attitudes within it. In recent years, there has been a great deal of effort to challenge those attitudes and to revise them. But as the discipline moves toward greater equality and inclusivity, the way it has indexed its work has unfortunately not. To course correct, we identify in this article some of the specific changes that are needed within (...) current indexing systems and propose a new model that could embody them. We use the Diversity Reading List in Philosophy as a case study and PhilPapers as a basis for comparison. The model we propose not only represents the discipline in a more inclusive and fair way, but it is also efficient, easy to use or implement, and adaptable for a variety of contexts. (shrink)

Within collective epistemology, there is a class of theories that understand the epistemic status of collective attitude ascriptions, such as ‘the college union knows that the industrial action is going to plan’, or ‘the jury justifiedly believes that the suspect is guilty’, as saying that a sufficient subset of group member attitudes have the relevant epistemic status. In this paper, I will demonstrate that these summativist approaches to collective epistemology are incompatible with epistemic permissivism, the doctrine that a single body (...) of evidence may rationalize multiple doxastic attitudes. In particular, I will make use of epistemic permissivism to provide a general recipe for generating so-called divergence cases, which demonstrate situations in which rationality requires group-level and member-level attitudes to diverge. I will call this class of cases permissive divergence cases. While other divergence cases have been discussed in the literature, permissive divergence cases prove themselves to be less susceptible to many of the worries raised against their competitors, while being directly built on an often-defended epistemological thesis.

This paper offers the first careful analysis of the possibility that AI and humanity will go to war. The paper focuses on the case of artificial general intelligence, AI with broadly human capabilities. The paper uses a bargaining model of war to apply standard causes of war to the special case of AI/human conflict. The paper argues that information failures and commitment problems are especially likely in AI/human conflict. Information failures would be driven by the difficulty of measuring AI capabilities, (...) by the uninterpretability of AI systems, and by differences in how AIs and humans analyze information. Commitment problems would make it difficult for AIs and humans to strike credible bargains. Commitment problems could arise from power shifts, rapid and discontinuous increases in AI capabilities. Commitment problems could also arise from missing focal points, where AIs and humans fail to effectively coordinate on policies to limit war. In the face of this heightened chance of war, the paper proposes several interventions. War can be made less likely by improving the measurement of AI capabilities, capping improvements in AI capabilities, designing AI systems to be similar to humans, and by allowing AI systems to participate in democratic political institutions.

Recent advances in natural language processing have given rise to a new kind of AI architecture: the language agent. By repeatedly calling an LLM to perform a variety of cognitive tasks, language agents are able to function autonomously to pursue goals specified in natural language and stored in a human-readable format. Because of their architecture, language agents exhibit behavior that is predictable according to the laws of folk psychology: they function as though they have desires and beliefs, and then make (...) and update plans to pursue their desires given their beliefs. We argue that the rise of language agents significantly reduces the probability of an existential catastrophe due to loss of control over an AGI. This is because the probability of such an existential catastrophe is proportional to the difficulty of aligning AGI systems, and language agents significantly reduce that difficulty. In particular, language agents help to resolve three important issues related to aligning AIs: reward misspecification, goal misgeneralization, and uninterpretability. (shrink)

Following recent arguments that cultural practices in wild animal populations have important conservation implications, we argue that recognizing captive animals as cultural has important welfare implications. Having a culture is of deep importance for cultural animals, wherever they live. Without understanding the cultural capacities of captive animals, we will be left with a deeply impoverished view of what they need to flourish. Best practices for welfare should therefore require concern for animals’ cultural needs, but the relationship between culture and welfare (...) is also extremely complex, requiring us to rethink standard assumptions about what constitutes and contributes to welfare.

One Stoic response to the skeptical indistinguishability argument is that it fails to account for expertise: the Stoics allow that while two similar objects create indistinguishable appearances in the amateur, this is not true of the expert, whose appearances succeed in discriminating the pair. This paper re-examines the motivations for this Stoic response, and argues that it reveals the Stoic claim that, in generating a kataleptic appearance, the perceiver’s mind is active, insofar as it applies concepts matching the perceptual stimulus. (...) I argue that this claim is reflected in the Stoic definition of the kataleptic appearance, and that it respects their more general account of mental representation. I further suggest that, in attributing some activity to the mind in creating each kataleptic appearance, and in claiming that the expert’s mind allows her to form more kataleptic appearances than the amateur, the Stoics draw inspiration from the wax tablet model in Plato’s Theaetetus (190e–196d), where Socrates distinguishes the wise from the ignorant on the basis of how well they match sensory input with its appropriate mental ‘seal’ (σφραγίς).

This paper considers the question of whether chimpanzees possess at least a primitive sense of normativity: i.e., some ability to internalize and enforce social norms—rules governing appropriate and inappropriate behaviour—within their social groups, and to make evaluations of others’ behaviour in light of such norms. A number of scientists and philosophers have argued that such a sense of normativity does exist in chimpanzees and in several other non-human primate and mammalian species. However, the dominant view in the scientific and philosophical (...) literature is that psychological capacities for social norms evolved uniquely in the human lineage, after our last common ancestor with chimpanzees and bonobos. After reviewing some of the existing evidence for normative capacity in chimpanzees, I defend the thesis of chimpanzee normativity against three key theoretical objections that have been presented in the literature, each of which have played a part in motivating the dominant sceptical position. I argue that, while we still have much to learn about the nature and extent of the normative capacities of other animals, there is strong prima facie evidence for social norms and normative evaluation in chimpanzees and the main theoretical objections to chimpanzee normativity are not at all compelling.

Despite well-established results in survey methodology, many experimental philosophers have not asked whether and in what way conclusions about folk intuitions follow from people’s responses to their surveys. Rather, they appear to have proceeded on the assumption that intuitions can be simply read off from survey responses. Survey research, however, is fraught with difficulties. I review some of the relevant literature—particularly focusing on the conversational pragmatic aspects of survey research—and consider its application to common experimental philosophy surveys. I argue for (...) two claims. First, that experimental philosophers’ survey methodology leaves the facts about folk intuitions massively underdetermined; and second, that what has been regarded as evidence for the instability of philosophical intuitions is, at least in some cases, better accounted for in terms of subjects’ reactions to subtle pragmatic cues contained in the surveys.

This paper models knowledge in cases where an agent has multiple experiences over time. Using this model, we introduce a series of observations that undermine the pretheoretic idea that the evidential significance of experience depends on the extent to which that experience matches the world. On the basis of these observations, we model knowledge in terms of what is likely given the agent’s experience. An agent knows p when p is implied by her epistemic possibilities. A world is epistemically possible (...) when its probability given the agent’s experiences is not significantly lower than the probability of the actual world given that experience. (shrink)

We develop a reading of Moore’s “Proof of an External World” that emphasizes the connections between this paper and Moore’s earlier concerns and strategies. Our reading has the benefit of explaining why the claims that Moore advances in “Proof of an External World” would have been of interest to him, and avoids attributing to him arguments that are either trivial or wildly unsuccessful. Part of the evidence for our view comes from unpublished drafts which, we believe, contain important clues concerning (...) Moore’s aims and intent. While our approach to PEW may be classified alongside other broadly "metaphysical" readings, we believe that a proper recognition of the continuity in Moore’s philosophical concerns and strategies across his philosophical career shows that the customary distinction between "epistemological" and "metaphysical" interpretative approaches to PEW is at best superficial.

Many defend the thesis that when someone knows p, they couldn’t easily have been wrong about p. But the notion of easy possibility in play is relatively undertheorized. One structural idea in the literature, the principle of Counterfactual Closure (CC), connects easy possibility with counterfactuals: if it easily could have happened that p, and if p were the case, then q would be the case, it follows that it easily could have happened that q. We first argue that while CC (...) is false, there is a true restriction of it to cases involving counterfactual dependence on a coin flip. The failure of CC falsifies a model where the easy possibilities are counterfactually similar to actuality. Next, we show that extant normality models, where the easy possibilities are the sufficiently normal ones, are incompatible with the restricted CC thesis involving coin flips. Next, we develop a new kind of normality theory that can accommodate the restricted version of CC. This new theory introduces a principle of Counterfactual Contamination, which says roughly that any world is fairly abnormal if at that world very abnormal events counterfactually depend on a coin flip. Finally, we explain why coin flips and other related events have a special status. A central take home lesson is that the correct principle in the vicinity of Safety is importantly normality-theoretic rather than (as it is usually conceived) similarity-theoretic. (shrink)

Scientific realism driven by inference to the best explanation (IBE) takes empirically confirmed objects to exist, independent, pace empiricism, of whether those objects are observable or not. This kind of realism, it has been claimed, does not need probabilistic reasoning to justify the claim that these objects exist. But I show that there are scientific contexts in which a non-probabilistic IBE-driven realism leads to a puzzle. Since IBE can be applied in scientific contexts in which empirical confirmation has not yet (...) been reached, realists will in these contexts be committed to the existence of empirically unconfirmed objects. As a consequence of such commitments, because they lack probabilistic features, the possible empirical confirmation of those objects is epistemically redundant with respect to realism. (shrink)

The mind-brain identity theory, the thesis that sensations are identical with properties or processes of the brain, was introduced into contemporary discussion by U.T. Place, Herbert Feigl, and J.J.C Smart in the 1950s. Despite its widespread rejection in the following decades, the identity theory has received several carefully articulated defenses in recent years. Aside from developing novel responses to well-known arguments against the identity theory, contemporary identity theorists have argued that the epistemological resources available to support the adoption of identities (...) are more plentiful than has often been supposed; further, they have argued that mind-brain identities allow for the resolution of otherwise intractable explanatory puzzles about the phenomenal properties of experience. From an epistemological perspective, identity theorists have thus argued that a central reason for believing theoretical identities—both mind-brain identities as well as more mundane identities such as water = H2O—stems from the explanatory power that they confer. Yet from an explanatory perspective, identity theorists have maintained that identities cannot themselves be explained; indeed, they have maintained that it is hardly intelligible to request an explanation for an identity. This paper considers these ideas draws out an important tension between them. The central claim is that insofar as identity theorists insist on the explanatorily efficacy of identities, they should concede that there is a good sense in which theoretical identities can be explained. However, it is moreover argued that this concession is not especially problematic and, indeed, ought to be welcomed by identity theorists. (shrink)

Simon Cushing conducted the following interview with Elizabeth Anderson on 18 June 2014.

This essay is an investigation into the sense of ‘able’ relevant to free will, where free will is understood as requiring the ability to do otherwise. I argue that van Inwagen's recent functional specification of the relevant sense of ‘able’ is flawed, and that explicating the powers involved in free will shall likely require paying detailed attention to the semantics and pragmatics of ‘can’ and ‘able’. Further, I argue that van Inwagen's promise-level ability requirement on free will is too strong. (...) I also argue that Mele's conjecture that the strength of the ability to perform the ‘alternative’ action be no higher than the strength of the ability exercised in performing an action is mistaken. I suggest there is an asymmetry in the strengths of the abilities which make up the n-way power that comprises free will, and that this looks to have some interesting consequences for the connection between the abilities required for free will and, e.g. the ‘up to us’ locution.

(Dall'introduzione del volume) Nel terzo capitolo Simone Ghelli si lancia nell’impresa di ipotizzare un percorso di lettura leviano di cui non è dato trovare riscontri filologici precisi, ma che è tuttavia percepibile “nell’aria” e nelle opere del torinese. Si tratta di una risonanza con il pensiero filosofico di Pierre Bayle e della sua riflessione sulla sofferenza nell’orizzonte speculativo di Levi, il quale tornò sovente a meditare sul problema del male e sulla spinosa questione dell’assenza di Dio e dell’impossibilità di fornire (...) una giustificazione della vita e del mondo. Ghelli arriva così a sostenere che «la posizione di Levi esprime una profonda consapevolezza filosofica, una concatenazione non casuale di concetti e argomenti riconducibile a una tradizione ben precisa: quella dell’ateismo moderno».

Under what conditions would an artificially intelligent system have wellbeing? Despite its clear bearing on the ethics of human interactions with artificial systems, this question has received little direct attention. Because all major theories of wellbeing hold that an individual’s welfare level is partially determined by their mental life, we begin by considering whether artificial systems have mental states. We show that a wide range of theories of mental states, when combined with leading theories of wellbeing, predict that certain existing (...) artificial systems have wellbeing. Along the way, we argue that there are good reasons to believe that artificial systems can have wellbeing even if they are not phenomenally conscious. While we do not claim to demonstrate conclusively that AI systems have wellbeing, we argue that there is a significant probability that some AI systems have or will soon have wellbeing, and that this should lead us to reassess our relationship with the intelligent systems we create.

Is the brain really a computer? In particular, is our intelligence a computational achievement: is it because our brains are computers that we get on in the world as well as we do? In this paper I will evaluate an ambitious new argument to the contrary, developed in Landgrebe and Smith (2021a, 2022). Landgrebe and Smith begin with the fact that many dynamical systems in the world are difficult or impossible to model accurately (inter alia, because it is intractable to (...) find exact solutions to the differential equations that describe them—meaning we have to approximate—but at the same time they are such that small differences in starting conditions lead to big differences in final conditions, thwarting accurate approximation). Yet we manage to survive and thrive in a world full of such systems. Landgrebe and Smith argue from these premises that it is not because our brains are computers that we get on as well as we do: instead it is because of the various ways that we dynamically couple with such systems, these couplings themselves impossible to model well enough to emulate in silico. Landgrebe and Smith thus defend a dynamical systems model in the lineage of Gibson (1979), Van Gelder (1995), and Thompson (2007), though their focus is on decisively refuting the computationalist alternatives rather than developing the positive account. Here I will defend the claim that human intelligence is genuinely computational (and that whole brain emulation and others forms of AGI may be possible) against this argument. (shrink)

The descriptions 'good' and 'bad' are examples of thin concepts, as opposed to 'kind' or 'cruel' which are thick concepts. Simon Kirchin provides one of the first full-length studies of the crucial distinction between 'thin' and 'thick' concepts, which is fundamental to many debates in ethics, aesthetics and epistemology.

The mindshaping hypothesis proposes a “de-intellectualized” explanation for human unique cooperation. In contrast to standard mindreading accounts, which emphasize the evolution of sophisticated reasoning about others’ propositional attitudes to explain how our ancestors became hyper cooperators, the hypothesis holds that sophisticated mindreading was a late-arriving product of our ancestors becoming better cooperators via the evolution of mechanisms that shape and regulate the minds of members of human groups to be suited to cooperation. Comparative research with nonhumans, especially our closest living (...) relatives, the great apes, is of utmost importance for evaluating the mindshaping hypothesis—for instance, to what extent can apes maintain relatively complex forms of culture and cooperation without reasoning about propositional attitudes? The concept of mindshaping also opens up new questions in comparative cognition that are worth exploring in their own right, such as whether apes regulate each other’s behavior via social norms. This chapter assesses what we currently do and do not know about the nature and extent of various mindshaping mechanisms in nonhuman great apes, focusing on culture and social learning, pedagogy, and social norms.

A distorted representation of one's own body is a diagnostic criterion and core psychopathology of both anorexia nervosa (AN) and bulimia nervosa (BN). Despite recent technical advances in research, it is still unknown whether this body image disturbance is characterized by body dissatisfaction and a low ideal weight and/or includes a distorted perception or processing of body size. In this article, we provide an update and meta-analysis of 42 articles summarizing measures and results for body size estimation (BSE) from 926 (...) individuals with AN, 536 individuals with BN and 1920 controls. We replicate findings that individuals with AN and BN overestimate their body size as compared to controls (ES= 0.63). Our meta-regression shows that metric methods (BSE by direct or indirect spatial measures) yield larger effect sizes than depictive methods (BSE by evaluating distorted pictures), and that effect sizes are larger for patients with BN than for patients with AN. To interpret these results, we suggest a revised theoretical framework for BSE that accounts for differences between depictive and metric BSE methods regarding the underlying body representations (conceptual vs. perceptual, implicit vs. explicit). We also discuss clinical implications and argue for the importance of multimethod approaches to investigate body image disturbance. (shrink)

Jag argumenterar för att oorganiserade kollektiv, såsom kollektivet av alla människor, kan handla moraliskt rätt och fel. Storskaliga problem likt den globala uppvärmningen är till exempel resultatet av en sådan kollektiv handling, nämligen hela mänsklighetens utsläpp av växthusgaser. Denna kollektiva handling är dessutom moraliskt fel, på grund av dess dåliga konsekvenser. Jag bemöter också en invändning mot denna uppfattning om kollektivt handlande, enligt vilken det är intuitivt orimligt att oorganiserade kollektiv såsom ”hela mänskligheten” kan handla.

I here defend microphysical manyism. According to microphysical manyism, each composite or higher-level object is a mere plurality of microphysical particles. After clarifying the commitments of the view, I offer two physicalist-friendly arguments in its favour. The first argument appeals to the Canberra Plan. Here I argue that microphysical particles acting in unison play the theoretical roles associated with composite objects - that they do everything that we think of composite objects as doing - and thus that composite objects are (...) to be identified with pluralities of microphysical particles. Along the way I rebut the objections that pluralities of particles don’t display the right emergent, ‘lingering’, or modal properties to be good candidates for identification with higher-level objects. In the second argument I claim that microphysical manyism is uniquely able to capture a compelling and widespread physicalist intuition concerning the intimate nature of the relationship between higher-level, composite objects and the microphysical world.

Place-based education is founded on the idea that the student’s local community is one of their primary learning resources. Place-based education’s underlying educational principle is that students need to first have an experiential understanding of the history, culture, and ecology of the environment in which they are situated before tackling broader national and global issues. Such attempts are a step in the right direction in dealing with controversial issues in a democracy by providing resources for synthesising curriculum though theory (curriculum (...) content, including traditional subjects) and practice (practical learning as experiential education). Nevertheless, many place-based accounts discount Indigenous conceptions of place, which are integral to Indigenous ways of knowing, being and doing, especially in relation to the ontological relationship to Land and Country. Indigenous philosophy has the potential to inform what place-based education means by students developing a ‘sense of place’ when engaging with local communities as their ‘own’ place. In this article we re-imagine the community of inquiry as a place-responsive pedagogy by learning from Indigenous philosophy, and recentring Indigenous notions of place in experiential learning. In addition to exploring the pedagogical potential of a place-responsive account of the community of inquiry, we look to the implications for teacher preparation. (shrink)
