    155. Henry Taylor | Mind and Natural Kinds

    What if vision, working memory, and consciousness are not the real joints of the mind, but just the words psychology happens to have inherited? My links: https://linktr.ee/frictionphilosophy. 1. Guest Henry Taylor is Associate Professor at the University of Birmingham, and his work has focused on various issues in metaphysics, mind, cultural robotics, and more. Check out his book, "Natural Kinds and the Science of Perception"! https://academic.oup.com/book/62599 https://a.co/d/0gUPbopl 2. Book Summary Taylor develops a property-cluster account of natural kinds tailored to psychology and states it as a sufficient condition, PNK: if a kind’s members instantiate a cluster of properties that co-occur non-accidentally, and the kind earns its keep in prediction, explanation, generalization, or discovery, it’s a psychological natural kind. Two commitments anchor the view — natural kinds are the kinds that serve science’s epistemic goals, and kindhood isn’t up to us, since the clustering has to answer to worldly structure. He deliberately strips the metaphysical commitments that homeostatic, causal, and stable cluster views carry, then defends the resulting liberality: the objection that PNK needs a supplementary mechanistic or causal explanation of the clustering is answered by distinguishing cases, and Block’s necessary-property objection gets a separate reply. Long-term memory serves as the worked example. Chapter 4 isolates the Eliminativist Claim — that a psychological term failing to pick out a natural kind should be dropped — motivates it via the epistemic privilege natural-kind terms enjoy, concedes that non-natural-kind terms can still be useful, and ends up defending a qualified version. The applications are where the framework does real work, and the results are non-uniform. Dorsal and ventral streams each come out as natural kinds — each a non-accidental property cluster with genuine epistemic payoff — which Taylor uses against scepticism about the two visual streams hypothesis. But that success generates a negative result one level up: because dorsal and ventral episodes differ so sharply, visual episode is not a cluster kind at all, but at best disjunctive — vision as jade. Working memory fares better. Taylor characterizes it via five properties (persistence duration, interaction with attention, manipulation of information, interfacing faculties, capacity), argues from partial-report and change-detection results that psychological explanations depend on their co-occurrence, and concludes it is both a natural kind and an explanatorily powerful one, contra recent scepticism about its unity. Chapter 8 then turns this on the unconscious-working-memory literature: the experiments don’t establish unconscious working memory, and the better reading is that in each case it’s vague whether the system involved is working memory. An appendix shows the cluster view is compatible with three major theories of vagueness. The closing chapters extend the method to prelinguistic infants, where verbal report and task instructions are unavailable. The proposal is deliberately theory-last: harvest markers of consciousness from adults, look for them in infants, and infer consciousness when enough co-occur — with natural kinds supplying the justification for that inference, and Taylor arguing the approach beats theory-first alternatives. He works through the complications honestly (behavioural vs. neuroscientific markers, the absence of any uncontroversial marker, detecting and correcting misleading ones, gradual emergence). Chapter 10 applies this to the early-vs-late emergence dispute between Bayne et al., Passos-Ferreira, and Taylor and Bremner, identifying two candidate clusters: an early one (third trimester to ~3 months: McGurk effect, default mode network, P3b-like ERP to global oddballs, endogenous attention, pain markers) and a later one (~1 year: protodeclarative pointing, means-ends reasoning, memory-based imitation). He declines to adjudicate, arguing instead that the evidence is genuinely muddy and that the natural-kinds machinery is what could resolve it — including the case where consciousness turns out to be associated with several cluster kinds rather than one, a jade-like outcome the framework can absorb without collapsing. 3.

    154. Justin Mooney | Phases of Objects

    When a lump of clay becomes a statue, does one thing get a new job, or does a brand-new thing come into being? My links: https://linktr.ee/frictionphilosophy. 1. Guest Justin Mooney is Assistant Professor of Philosophy at College of the Holy Cross, and his work has focused on metaphysics, philosophy of religion, and more. Check out his recent book, "Phases of Objects"! https://academic.oup.com/book/62226 https://a.co/d/0eL5AfF9 2. Book Summary Phases of Objects by Justin Mooney (Oxford University Press, 2026) is a work of analytic metaphysics defending a controversial view Mooney calls “phasalism”: the thesis that material objects are not permanent members of their kinds but can survive changes from one kind to another, so long as such changes violate no generic requirements on identity and persistence that hold for all material objects regardless of kind. This directly opposes what Mooney takes to be contemporary orthodoxy—”substantialism,” the widely-held and usually unexamined assumption that objects belong to their kinds permanently and essentially. His entry point is the classic puzzle of the statue and the lump of clay: whereas most solutions treat the statue and the clay as either identical or as two coincident objects, Mooney argues they are one and the same object, with the lump merely coming to “be” a statue in the same way a human person comes to be an adult by maturing. Being a statue, on his view, is a phase the clay passes through, not a new substance. The book builds this position out into a general metaphysics of material objects across five chapters. After laying methodological and metaphysical groundwork and distinguishing phase sortal changes (where the object before and after are numerically identical) from substance sortal changes (where they are distinct), Mooney proposes a phasalist criterion of identity—a broadly spatiotemporal account of persistence conditions—and tests it against a range of cases. He then deploys phasalism against the standard coincidence puzzles that motivate rival theories, arguing it handles sortal changes, gradual material turnover, undetached parts, and fission and fusion cases. A further chapter tackles “sameness relations,” where he defends the surprising pairings of identity without sameness and sameness without identity, showing how his framework accommodates our ordinary talk about objects being “the same” in various respects. The final chapter turns to what phasalism means for persons. Mooney argues his metaphysics pairs most naturally with animalism—the view that each of us is identical to a human organism, with personhood itself being a phase sortal property the animal comes to instantiate once sufficiently psychologically developed. From his general spatiotemporal criterion he derives a criterion of identity for human persons and applies it to the hard cases at the edges of a life: fertilization, the early embryo, twinning, and the fetus at the beginning, and persistent vegetative states, death, and decomposition at the end, closing with brain-transplant thought experiments. Throughout, Mooney is explicit that his aim is a partial defense—developing phasalism, drawing out its virtues, and rebutting objections—rather than a knockdown argument that it should be preferred to every rival, positioning the view as a serious and unjustly neglected competitor in the metaphysics of material objects. 3.

    153. David Papineau | Mind is Physical

    Is the hard problem of consciousness a real problem, or a question that dissolves once you take physicalism seriously? My links: https://linktr.ee/frictionphilosophy. 1. Guest David Papineau is Professor of Philosophy at King's College, London, and his work has focused on epistemology, metaphysics, the philosophy of science, and mind. 2. Interview Summary Papineau opens by characterizing physicalism via Kripke’s creation metaphor: once God has arranged all the material stuff, the work is done — no further act is needed to install minds. On defining “physical,” he takes the via negativa: whatever isn’t fundamentally mental or vital. He concedes this is cheap but insists it’s adequate for the mind-body problem, since the interesting conclusion is just that the mental is identical to something non-mental; Alyssa Ney has convinced him that a general physicalism about everything owes more (roughly, a few mathematically characterizable basic quantities). He also flags his student Jonathan Emery’s line that one needn’t argue for universal causal closure at all — the relevant question is whether everything going on inside our heads is physical — and grants the point is reasonable, while noting the physicalist still needs a non-question-begging characterization of “brain process” broad enough to cover glia, fields, and whatever physics hasn’t found yet. On the hard problem, he simply rejects the presupposition: brain processes don’t give rise to consciousness; they are consciousness, as H2O arrangements don’t give rise to water. Identities need no explanation — he retells Block’s Twain/Clemens anecdote — and the same applies to generic consciousness if it turns out identical to global workspace activity or reentrant loops. Chalmers’ residue reduces to a tractable question about the reference of phenomenal concepts, settled empirically. He disowns functionalism as a metaphysical mess (second-order role properties can’t be pains, since pains occupy the roles), preferring generic first-order physical properties on the determinable/determinate model, and treats metaphysically necessary supervenience as an artifact of Jackson and Chalmers needing a single common commitment to attack. He then presses the consequence most physicalists flinch at: consciousness is vague like intelligence, with genuine borderline cases among animals and AI systems — Tye found this incredible enough to turn panpsychist. His own response is to decouple the issues, per his paper “Consciousness Is Not the Key to Moral Standing”: the clustered features that make consciousness matter morally in us come apart in other creatures, so moral standing should be settled first and consciousness bracketed, contra Birch’s precautionary framing. The final stretch tracks the anti-physicalist dialectic from the knowledge argument through the two-dimensional argument to the current revelation-based versions (Goff, Nida-Rümelin, Liu), which Papineau credits for isolating the real load-bearing premise once the bad inference from semantic to epistemic directness is discarded. His objection is ontological and blunt: he cannot identify any proposition you acquire by introspecting pain beyond that pain is pain. Comparative knowledge (yellow resembling orange more than red) is fine; “knowing what it’s like” isn’t knowledge — the cup doesn’t thereby know what whiteness is like. He extends the complaint to Russellian monist quiddities: instantiating a property and being able to name it confers no information about it. On causal closure he declines the appeal to authority and rests on the historical evidence — the collapse of vital and nervous forces, intracellular electrochemistry, Hodgkin-Huxley — plus Sean Carroll’s argument that brain-localized forces at those energy scales would have shown up in colliders, while acknowledging Emery finds holes in it and conceding that bare miraculous interference violating energy conservation falls outside Carroll’s argument’s reach. A brief exchange on whether phenomenal concepts are twin-earthable (he thinks not, though tentatively) precedes his closing remark that philosophy’s value lies in the fact that some humans can’t help being puzzled by puzzling things. 3.

    152. Daniel Stoljar | The Introspection Principle

    What if introspection isn’t an inner eye watching your own mind, but simply what rationality requires of you? My links: https://linktr.ee/frictionphilosophy. 1. Guest Daniel Stoljar is Professor of Philosophy at the Australian National University, and his work has focused on philosophy of mind, philosophy of language, metaethics, metaphysics, and metaphilosophy. Check out his recent book, "The Introspection Principle: Rationalism about Knowledge of Consciousness"! https://academic.oup.com/book/63008 https://a.co/d/0gWXxovb 2. Book Summary Daniel Stoljar’s The Introspection Principle: Rationalism about Knowledge of Consciousness sets out to explain what introspection is — defined nominally as the distinctive way we come to know or reasonably believe that we’re in psychological states that are conscious — and to defend a single unified theory of it. The theory is the rationalist account, built around the titular principle: if you are in a conscious state, you should believe that you are, ceteris paribus and given background conditions. Two theses do the work. First, that this is a genuine principle of rationality, on a par with principles enjoining you to believe the obvious consequences of your beliefs, to coordinate belief with perception, and to act on your beliefs. Second, that you have a capacity for introspection iff you abide by it. Introspective belief is thus the manifestation of a rational disposition, and introspective knowledge is introspective belief that amounts to knowledge — so consciousness turns out to be built into the content of rationality. The first four chapters lay the groundwork. Chapter 2 defends an inclusive notion of a conscious state — one having enough of phenomenal character, awareness, attention, cerebral celebrity, and poise — against the more familiar exclusive (phenomenal, higher-order, access) definitions, while allowing rival theories to help themselves to exclusive notions if useful. Chapter 3 states the principle and fields twenty preliminary questions; chapter 4 contrasts it with the perceptual/inner-sense tradition, endorsing Shoemaker’s critique. The diagnostic offered there structures the whole book: rivals divide into those that accept the principle but embellish it unnecessarily (acquaintance theories, perceptual theories, the “simple” account of Smithies and Peacocke), and those that reject it and thereby become implausible (Shoemaker’s constitutivism, inferentialism). Stoljar positions himself as a synthesis of Armstrong and Shoemaker that departs from both — the connection between conscious state and introspective belief is normative necessity, not metaphysical or natural necessity, and the principle is wide-scope rather than narrow-scope, so it doesn’t collapse into the truth principle. The remaining thirteen chapters function as a case book, each applying the account to a standing problem: Dretske’s evidence problem (solved via a warrant/evidence distinction), Evans on transparency and Moore on diaphanousness (both accommodated by taking introspectable states to be access conscious), acquaintance, the truth principle, Shoemaker on necessity, privileged access (accepting Byrne’s “different from” thesis while rejecting “better than”), Williamson’s anti-luminosity argument (defused by distinguishing exceptionless from generic luminosity, with only the latter required), Sosa on negative introspection (handled via second-order total-state contents), McKinsey’s externalism incompatibility (rebutted by treating externalism as a posteriori and contingent), Nisbett and Wilson on inference, revelation — which Stoljar rejects, and uses to argue against Kammerer and Frankish’s illusionism — and finally the cogito, where he claims both Descartes and Hume come out partly right, against Cassam’s triviality charge. The concluding argument is abductive rather than direct: the rationalist account earns its place by explaining this whole cluster of puzzles at once, where rivals were each engineered for one. 3.

    151. María Martinez Alles | Torts and Retribution

    What if the point of punitive damages isn’t just to punish wrongdoers, but to tell victims their dignity actually counts? My links: https://linktr.ee/frictionphilosophy. 1. Guest María Guadalupe Martínez Alles is Associate Professor of Law at Sturm College of Law, and her work has focused on the philosophy of law. Check out her recent book, "Torts and Retribution: The Case for Punitive Damages"! https://www.cambridge.org/core/books/torts-and-retribution/6C2E6812DA1D2071DA90DA286FC70285https://a.co/d/06f7e0Kb 2. Book Summary María Guadalupe Martínez Alles’s Torts and Retribution: The Case for Punitive Damages (Cambridge University Press, 2025) sets out to build what she argues has long been missing from tort scholarship: a thorough, cross-jurisdictional theoretical justification for the retributive dimension of tort law, as embodied in punitive damages. She observes that punitive damages sit awkwardly between civil and criminal law—awarded in private lawsuits yet explicitly punitive and noncompensatory—and that the dominant camps in tort theory have mostly avoided reckoning with this. Rights-based and corrective-justice theorists tend either to dismiss punishment as an anomaly or to force it into a compensatory framework, while law-and-economics accounts simply collapse punishment into deterrence. Against this backdrop, Martínez Alles takes the “punishment and deterrence” formula seriously by reconstructing it as “retribution and deterrence,” arguing that stripping punitive damages of their retributive content would gut them of something essential, and that the real question is how retribution and deterrence interact rather than which one to choose. The book’s central contribution is a framework she coins Relational Retribution, developed across its four parts (the place of punishment in torts, the retributive rationale, retribution in the mass-market setting, and why tort law specifically is the right venue). Rather than grounding punitive damages solely in the “just deserts” owed for a defendant’s reprehensible conduct, Relational Retribution shifts attention to the relationship between wrongdoer and victim and to the victim’s own motivations for seeking a punitive award. Drawing on empirical work in cognitive and social psychology, decision-making research, and moral philosophy’s discussion of “reactive attitudes,” she reconceives the tort victim—not as an abstract figure seeking mere restoration to a prior state, but as a value-laden moral agent responding to wrongs that threaten their dignity, autonomy, and worth. On this reading, victims pursue punitive damages less for private vengeance than for denunciation and value affirmation: punitive damages become a mode of moral communication that condemns the wrongdoer, affirms the victim’s equal moral standing, and reinforces society’s other-regarding values. Martínez Alles extends this framework to contemporary mass-market contexts—product liability, risk regulation, and new technologies—recasting punitive damages there as retributive sanctions for violations of collective societal trust. She also directly confronts the standard objection that punitive damages represent a dangerous “privatization” of the state’s monopoly on punishment, reframing the issue not as whether citizens may punish one another but as a choice between channeling punishment through privately initiated yet judicially regulated processes (tort law) versus publicly controlled ones (criminal law). The book closes by defending the distinctive significance of both the tort victim and the tort process, portraying tort litigation as a legitimate, complementary forum—alongside criminal and regulatory institutions—where communities air harms, assign accountability, and refine shared standards of conduct. Ultimately, it invites tort and criminal law scholars alike into a broader conversation about the forms punishment can take in democratic societies beyond the confines of criminal law. 3.

    150. Kristie Miller | Life in Four Dimensions

    What if the flow of time is an illusion, and the past, present, and future all exist together right now? My links: https://linktr.ee/frictionphilosophy. 1. Guest Kristie Miller is the Challis Professor of Philosophy at the University of Sydney and co-director of the interdisciplinary Centre for Time. Her work has focused on metaphysics, especially as it relates to time, temporal passage, identity, and agency.Check out her recent book, "Life in Four Dimensions: A Defence of the Block Universe Theory"!https://academic.oup.com/book/62313https://a.co/d/04YERGhM 2. Book Summary Life in Four Dimensions: A Defence of the Block Universe Theory argues for the block universe view of time—the thesis that reality is a four-dimensional spacetime block in which all events (past, present, and future) exist, with no objective, non-perspectival fact about which events are “really” present. On this static picture, what exists never changes and nothing has the property of being objectively present; talk of past, present, and future is merely talk about where events sit relative to one’s own location. The author’s central target is not dynamical theories of time themselves (presentism, the growing block, the moving spotlight), but a specific family of arguments against the block view, which he calls the General Inference-to-the-Best-Explanation (IBE) argument: the world seems to us as though time robustly passes, the best explanation for this seeming is that time really does pass, and therefore time passes. Rather than taking the usual “gaps” route—conceding the world seems dynamical but explaining that seeming away—the book defends the bolder “no gaps” approach, contending that we live in a block universe and that it seems to us as though we do. What distinguishes the book methodologically is its blend of analytic argument with experimental philosophy: the author reports over forty empirical studies, conducted with collaborators, probing what he terms the “manifest temporal image”—how time actually seems to ordinary people—rather than relying on armchair pronouncements about how things collectively seem. After laying out a precise version of the block view in Chapter 1 (built on two theses, “No Change in Existence” and “No Objective Present,” plus assumptions about spacetime drawn from general relativity), the book works through four variants of the IBE argument. Chapters 2–4 attack the Experiential version, defending “deflationism”—the claim that we do not in fact have experiences as of robust passage—and arguing it better explains people’s reported temporal seemings. Chapter 5 takes on the Conceptual version, presenting evidence that our time-related concepts would not fail to be satisfied in a block world; Chapter 6 addresses the Attitude/Preference version (tensed emotions like relief and dread, and future-biased preferences), arguing what makes such attitudes fitting are perspectival facts that obtain in block worlds too; and Chapter 7 examines the Belief version, marshalling data showing considerable population-level variation in what people actually believe about passage. Having dismantled each route from “seemings” to dynamism, Chapter 8 goes on the offensive, offering a positive IBE for the block view—arguing it better explains our asymmetric knowledge of past versus future—and contending that robust temporal passage is explanatorily redundant, doing no genuine work (including no work in explaining the asymmetry of physical processes). Since positing passage explains nothing, the author concludes, we ought not posit it, and should accept the block view. The overall achievement is twofold: a sustained defense of a static, four-dimensional metaphysics of time, and a demonstration—of interest even to those unmoved by the block view—that many influential arguments in the metaphysics of time, all of which lean on claims about how time seems, rest on empirical assumptions that the actual evidence about human temporal experience does not support. 3.

    149. Mark Balaguer | How to Be a Presentist

    What if only the present moment exists, and everything you call the past or the future is, strictly speaking, nothing at all? My links: https://linktr.ee/frictionphilosophy. 1. Guest Mark Balaguer is professor of philosophy at Cal State LA, and his research has covered a wide range of topics, including metaphysics, philosophy of mathematics, philosophy of language, philosophy of logic, free will, and metaethics. Check out his book, "How to Be a Presentist"!https://global.oup.com/academic/product/how-to-be-a-presentist-9780197845714https://a.co/d/009UAUtC 2. Book Summary Balaguer’s book sets out to develop and defend an original version of presentism — the view in the philosophy of time that only present objects exist, with no past or future objects in the inventory of reality. Crucially, Balaguer is not arguing that presentism is true; his project is the more modest one of showing that presentism is a live, defensible position and that, if there is a fact of the matter at all, the question of its truth is an open empirical one rather than something settleable by armchair metaphysics. The book is organized around three classical objections to presentism: the ontological-commitment objection (that true sentences like “Obama admires Gandhi” seem to require past objects to exist), the truthmaking objection (that truths about the past need something in reality to make them true), and the special-relativity objection (that physics rules out a privileged “now”). The first part of the book lays metaphilosophical groundwork, arguing against trivialism, against necessitarianism about metaphysics, and in favor of an “anti-metaphysicalist” stance on which presentism, if factual, is a contingent empirical hypothesis rather than something knowable a priori. Part II then mounts the defense proper. Against the ontological-commitment objection, Balaguer endorses a sweeping “FAPP-ist” error theory: the relevant ordinary and scientific sentences about past or future objects are, strictly speaking, false, but they function fine “for all practical purposes.” Against the truthmaking objection, he develops a position he calls nothingism, on which past-tense sentences that presentists count as true don’t have truthmakers because they aren’t really making claims about reality at all. Against special relativity, he constructs a relativized presentism compatible with the relativity of simultaneity, avoiding any appeal to a privileged frame. He also takes on subsidiary worries about time travel and change. The book’s most distinctive move comes in Part III, where Balaguer pushes presentism toward what he calls metaphysically minimal or timeless presentism. Here he argues — surprisingly, given the near-universal assumption that presentists must endorse the A-theory — that presentists should reject the existence of time itself, of times (including the present time), of temporal passage, and of metaphysically substantive A-facts (facts about something being past, present, or future). On the resulting picture, talk of time is best treated as a useful fiction layered over a more fundamental notion of intrinsic change, yielding a presentism that is ontologically lean, empirically respectable, and stripped of the heavy metaphysical machinery usually thought to come with the view. The overall result is a defense of presentism that is at once more concessive (presentism is not proven, just shielded from refutation) and more radical (presentism without time) than standard treatments in the literature. 3.

    148. Matt Duncan | Acquaintance

    What if simply having something consciously present to mind already counts as a form of knowledge, and helps explain not just perception, but beauty, emotion, and moral life? My links: https://linktr.ee/frictionphilosophy. 1. Guest Matt Duncan is Professor of Philosophy at Rhode Island College, and his work has focused on metaphysics, epistemology, and mind, including the nature of experience and experiential knowledge. Check out his book, "Present to the Mind: Acquaintance and Its Significance"! https://academic.oup.com/book/62315 https://a.co/d/0i7cd8zC 2. Book Summary In Present to the Mind, Matt Duncan develops and defends a Russellian-style notion of ‘acquaintance’: an especially direct form of conscious awareness we bear to things present in experience, such as colors, sounds, pains, smells, and other phenomenal features. The book begins from a striking question about when your ‘epistemic day’ starts. Against the orthodox view that perceptual knowledge arrives only after experience gives rise to belief, Duncan argues that conscious awareness itself already puts us in touch with reality in a knowledge-involving way. The book is organized around three main claims: acquaintance exists, acquaintance is a form of knowledge, and acquaintance is deeply significant in human life. The middle of the book argues first that several forms of acquaintance are real, and then that acquaintance is not just epistemically useful but itself a distinctive kind of knowledge. Duncan’s core idea is that some knowledge of things is constituted by conscious awareness rather than by belief: in perception, you do not first see, then believe, then know; rather, you can see and thereby know. From there he develops an account of ‘knowledge of things’ that is meant to work across different theories of experience, and he argues that acquaintance plays a foundational epistemic role by helping justify beliefs and underpinning much empirical knowledge, even if it is non-propositional. The final chapters broaden the project beyond epistemology. Duncan argues that acquaintance is aesthetically significant because genuine aesthetic appreciation depends on conscious awareness of aesthetically relevant features; emotionally significant because acquaintance with affective experience helps us know and appreciate the value of people; and morally significant because what we are able to notice and know is intertwined with moral character, producing a reciprocal moral-epistemic relationship. So the book’s overall message is not just that acquaintance is a defensible theoretical posit in philosophy of mind and epistemology, but that it is a basic feature of how we encounter beauty, respond to others, and live morally. Duncan’s concluding thought is that acquaintance matters every day, from ordinary perception all the way to our deepest forms of appreciation and care. 3.
