This is a survey article on reductive views of shared intention.

A prominent view of phenomenal consciousness combines two claims: (i) the identity conditions of phenomenally conscious states can be fully accounted for in terms of these states’ representational content; (ii) this representational content can be fully accounted for in non-phenomenal terms. This paper presents an argument against this view. The core idea is that the identity conditions of phenomenally conscious states are not fixed entirely by what these states represent (their representational contents), but depend in part on how they represent (...) (their representational attitudes or modes). The argument highlights the myriad liabilities and difficulties one must accrue when one tries to appeal only to what phenomenally conscious states represent in accounting for their phenomenal individuation.

Ethicists struggle to take reductive views seriously. They also have trouble conceiving of some supervenience failures. Understanding why provides further evidence for a kind of hybrid view of normative concept use.

Approaches to the naturalization of phenomenology usually understand naturalization as a matter of rendering continuous the methods, epistemologies, and ontologies of phenomenological and natural scientific inquiry. Presupposed in this statement of the problematic, however, is that there is an original discontinuity, a rupture between phenomenology and the natural sciences that must be remedied. I propose that this way of thinking about the issue is rooted in a simplistic understanding of the phenomenological reduction that entails certain assumptions about the subject matter (...) of phenomenology and its relationship to the natural sciences. By contrast, Merleau‐Ponty's first work, The Structure of Behavior, presents a radically different approach to the phenomenological reduction, one that traverses the natural sciences and integrates them into phenomenology from the outset. I outline the argument for this position in The Structure of Behavior and then discuss consequences for current methodological issues surrounding the naturalization of phenomenology, focusing on the relationship between empirical sciences of mind, phenomenological psychology, and transcendental phenomenology. This novel exegesis of Merleau‐Ponty's view on the reduction offers new insight into his oft‐quoted remark that the phenomenological reduction is impossible to complete. (shrink)

Safety principles in epistemology are often hailed as providing us with an explanation of why we fail to have knowledge in Gettier cases and lottery examples, while at the same time allowing for the fact that we know the negations of sceptical hypotheses. In a recent paper, Sinhababu and Williams have produced an example—the Backward Clock—that is meant to spell trouble for safety accounts of knowledge. I argue that the Backward Clock case is, in fact, unproblematic for the more sophisticated (...) formulations of safety in the literature. However, I then proceed to construct two novel examples that turn out problematic for those formulations—one that provides us with a lottery-style case of safe ignorance and one that is a straightforward case of unsafe knowledge. If these examples succeed, then safety as it is usually conceived in the current debate cannot account for ignorance in all Gettier and lottery-style cases, and neither is it a necessary condition for knowledge. I conclude from these troublesome examples that modal epistemologists ought to embrace a much more simple and non-reductive version of safety, according to which the notion of similarity between possible worlds that determines in which worlds the subject must believe truly is an epistemic notion that cannot be defined or reduced to notions independent of knowledge. The resulting view is shown to also lead to desirable results with respect to lottery cases, certain quantum phenomena, and a puzzling case involving a cautious brain-in-a-vat. (shrink)

The received view about emergence and reduction is that they are incompatible categories. I argue in this paper that, contrary to the received view, emergence and reduction can hold together. To support this thesis, I focus attention on dynamical systems and, on the basis of a general representation theorem, I argue that, as far as these systems are concerned, the emulation relationship is sufficient for reduction (intuitively, a dynamical system DS1 emulates a second dynamical system DS2 when DS1 exactly reproduces (...) the whole dynamics of DS2). This representational view of reduction, contrary to the standard deductivist one, is compatible with the existence of structural properties of the reduced system that are not also properties of the reducing one. Therefore, under this view, by no means are reduction and emergence incompatible categories but, rather, complementary ones. (shrink)

Fetal reduction is the practice of reducing the number of fetuses in a multiple pregnancy, such as quadruplets, to a twin or singleton pregnancy. Use of assisted reproductive technologies increases the likelihood of multiple pregnancies, and many fetal reductions are done after in vitro fertilisation and embryo transfer, either because of social or health-related reasons. In this paper, I apply Joe Horton’s all or nothing problem to the ethics of fetal reduction in the case of a twin pregnancy. I argue (...) that in the case of a twin pregnancy, there are two intuitively plausible claims: abortion is morally permissible, and it is morally wrong to abort just one of the fetuses. But since we should choose morally permissible acts rather than impermissible ones, the two claims lead to another highly implausible claim: the woman ought to abort both fetuses rather than only one. Yet, this does not seem right. A plausible moral theory cannot advocate such a pro-death view. Or can it? I suggest ways to solve this problem and draw implications for each solution. There are no data in this work. (shrink)

In `Essence and Modality', Kit Fine proposes that for a proposition to be metaphysically necessary is for it to be true in virtue of the nature of all objects whatsoever. Call this view Fine's Thesis. This paper is a study of Fine's Thesis in the context of Fine's logic of essence (LE). Fine himself has offered his most elaborate defense of the thesis in the context of LE. His defense rests on the widely shared assumption that metaphysical necessity obeys the (...) laws of the modal logic S5. In order to get S5 for metaphysical necessity, he assumes a controversial principle about the nature of all objects. I will show that the addition of this principle to his original system E5 leads to inconsistency with an independently plausible principle about essence. In response, I develop a theory that avoids this inconsistency while allowing us to maintain S5 for meta- physical necessity. However, I conclude that our investigation of Fine's Thesis in the context of LE motivates the revisionary conclusion that metaphysical necessity obeys the principles of the modal logic S4, but not those of S5. I argue that this constitutes a distinctively essentialist challenge to the received view that the logic of metaphysical necessity is S5. (shrink)

Given some reasonable assumptions concerning the nature of mental causation, non-reductive physicalism faces the following dilemma. If mental events cause physical events, they merely overdetermine their effects (given the causal closure of the physical). If mental events cause only other mental events, they do not make the kind of difference we want them to. This dilemma can be avoided if we drop the dichotomy between physical and mental events. Mental events make a real difference if they cause actions. But (...) actions are neither mental nor physical events. They are realized by physical events, but they are not type-identical with them. This gives us non-reductive physicalism without downward causation. The tenability of this view has been questioned. Jaegwon Kim, in particular, has argued that non-reductive physicalism is committed to downward causation. Appealing to the nature of actions, I will argue that this commitment can be avoided.

A common compatibilist view says that we are free and morally responsible in virtue of the ability to respond aptly to reasons. Many hold a version of this view despite disagreement about whether free will requires the ability to do otherwise. The canonical version of this view is reductive. It reduces the pertinent ability to a set of modal properties that are more obviously compatible with determinism, like dispositions. I argue that this and any reductive view of abilities (...) faces a significant challenge: it cannot adequately explain the freedom-grounding element of this ability. The problem has the form of a dilemma. This leaves reasons-responsive compatibilists with two options: abandon theories of free will grounded in abilities or abandon reductive theories of abilities.

The main message of the paper is that there is a disconnect between what many philosophers of mind think of as the scientific practice of reductive or reductionist explanation, and what the most relevant scientific work is actually like. I will sketch what I see as a better view, drawing on various ideas in recent philosophy of science. I then import these ideas into the philosophy of mind, to see what difference they make.1 At the end of the paper (...) I address a possible objection: the familiar package of ideas I reject in the philosophy of science should not be lightly discarded, because other popular views on fundamental issues depend on positions that I want to reject. I reply that those apparently attractive further ideas are not worth holding onto. (shrink)

In the article, Twin pregnancy, fetal reduction and the ‘all or nothing problem’, I argued that there is a moral problem in multifetal pregnancy reduction from a twin to a singleton pregnancy. Drawing on Horton’s original version of the ‘all or nothing problem’, I argued that there are two intuitively plausible claims in 2-to-1 MFPR: aborting both fetuses is morally permissible, aborting only one of the twin fetuses is morally wrong. Yet, with the assumption that one should select permissible choice (...) over impermissible choice, the two claims lead to a counter-intuitive conclusion: the woman ought to abort both fetuses rather than only one. It would be odd to promote such a pro-death view. Begović _et al_ discuss my article and offer insightful criticism, claiming, that there is no ‘all or nothing problem’ present in 2-to-1 MFPR. In this short reply, I respond to some of their criticism. (shrink)

Non-reductive physicalism is committed to two theses: first, that mental properties are ontologically autonomous, and second, that physicalism is true. Jaegwon Kim has argued that this view is unstable – to honor one thesis, one must abandon the other. In this paper, I present an account of property realization that addresses Kim’s criticism and that explains how the two theses are indeed comfortably compatible.

Let propositionalism be the thesis that all mental attitudes are propositional. Anti-propositionalists typically point at apparently non-propositional attitudes, such as fearing a dog and loving a spouse, and play defense against attempts at propositional analysis of such attitudes. Here I explore the anti-propositionalist’s prospects for going on the offensive, trying to show that some apparently propositional attitudes, notably belief and judgment, can be given non-propositional analysis. Although the notion that belief is a non-propositional attitude may seem ludicrous at first, it (...) is admirably defended by Franz Brentano, whose analysis I propose to expound, update, and deepen here. The basic strategy can be thought of as follows. First, although the grammar of belief-that reports clearly suggests a propositional attitude, the grammar of belief-in reports suggests instead an ‘objectual’ attitude. Second, with some ingenuity all belief-that reports can be paraphrased into belief-in reports. Third, given certain general considerations, this paraphraseability recommends the view that the psychological reality of belief states is objectual rather than propositional. Nonetheless, I will argue, there are two very real costs associated with this non-propositional analysis of belie. (shrink)

One of the greatest philosophical disputes in Germany in the latter half of the 19th century concerned the value of life. Following Arthur Schopenhauer, numerous philosophers sought to defend the provocative view that life is not worth living. A persistent objection to pessimism is that it is not really a philosophical theory at all, but rather a psychological state; a mood or disposition which is the product of socio-economic circumstance. A developed and influential version of this view was advanced in (...) the 1870’s by the English psychologist James Sully. Yet, as important as Sully’s critique was for the pessimism dispute, it has been almost entirely overlooked in the history of philosophy. With some growing recent attention to 19th century pessimism, this paper aims to reconstruct Sully’s view, and what I argue is his primary argument for it in terms of the best explanation for an alleged historical correlation between pessimistic belief and social hardship in the form of frustrated ideals. The paper then presents and analyses some challenges to this argument, some of which are argued to have been at least partially anticipated in the 19th century by the likes of Schopenhauer and Olga Plümacher.

The importance of the exclusion argument for contemporary physicalism is emphasized. The recent attempts to vindicate reductive physicalism by invoking certain needed revisions to the Nagelian model of reduction are then discussed. It is argued that such revised views of reduction offer in fact much less help to reductive physicalism than is sometimes supposed, and that many of these views lead to trouble when combined with the exclusion argument.

Speaks defends the view that propositions are properties: for example, the proposition that grass is green is the property being such that grass is green. We argue that there is no reason to prefer Speaks's theory to analogous but competing theories that identify propositions with, say, 2-adic relations. This style of argument has recently been deployed by many, including Moore and King, against the view that propositions are n-tuples, and by Caplan and Tillman against King's view that propositions are facts (...) of a special sort. We offer our argument as an objection to the view that propositions are unsaturated relations. (shrink)

The following essay stems from my interest in finding out whether Taminiaux’s appealing and well-argued reading of the Greek and Platonic connivance between theôria and poiêsis in contrast to the fragility and contingency of human practical judgments and the human intrigue of our worldly abode—a reading that in his view is retrieved by modern and contemporary German philosophers, including Heidegger—may be applied to Husserl’s transcendental phenomenology and reduction. In my view, Taminiaux’s original and piercingly acute reading of the history of (...) philosophy is above all due to his close and severe scrutiny of texts transmitted by the tradition, in dialogue with our experience of the “matters themselves.” Following this spirit, I risk an alternative reading of the phenomenological reduction, and specifically of its transcendental version, as an eminently practical—namely, ethical—achievement, driven by a practical virtue, responsibility.

In this paper significant challenges are raised with respect to the view that explanation essentially involves unification. These objections are raised specifically with respect to the well-known versions of unificationism developed and defended by Michael Friedman and Philip Kitcher. The objections involve the explanatory regress argument and the concepts of reduction and scientific understanding. Essentially, the contention made here is that these versions of unificationism wrongly assume that reduction secures understanding.

In his paper “What the externalist can know a priori”, Paul Boghossian rejects the compatibility between self-knowledge and content externalism by arguing that compatibilists are committed to the absurd view that a subject can know, by reasoning purely a priori, substantive truths about the world, such as that water exists. In this paper I try to show that Boghossian’s incompatibilist argument does not succeed. According to Boghossian, it is enough, for an externalist to reach the undesired conclusion, that she satisfies (...) a number of conditions that can be known by her a priori. I argue that, by an externalist’s lights, some of these conditions are simply too weak to be acceptable by her and some of them can only be known a posteriori. So, compatibilists are not committed to the absurdity Boghossian ascribes to them. (shrink)

This essay critiques the return to objects posited by certain new materialisms, most specifically the speculative realism of Harman, Meillassoux and Brassier. It argues that their “non-relational” and “autonomous” ontology represents a neo-positivist conception of reality. In place of such an atomistic ontology, I will suggest that the new materialisms develop a more productive, “non-reductive materialism”—a term drawn from analytic philosophy of mind. I will interpret Merleau-Ponty and Jean-Luc Nancy as crucial examples of such a materialism on the continental (...) side. Rather than being based on the non-relational innerness of an object, this position instead takes into account matter’s fundamentally extended nature. Confirmed by examples such as the growing evidence for neuroplasticity, the externalist, non-reductive view advances the new materialist argument that matter is “agentive” and “active” rather than “mechanic” and “passive,” without slipping into an anti-social-constructionist biologism or behaviorism.

Phenomenal intentionality is irreducible. Empirical investigation shows it is internally-dependent. So our usual externalist (causal, etc.) theories do not apply here. Internalist views of phenomenal intentionality (e. g. interpretationism) also fail. The resulting primitivist view avoids Papineau's worry that terms for consciousness are highly indeterminate: since conscious properties are extremely natural (despite having unnatural supervenience bases) they are 'reference magnets'.

Kripke in his famous book on Wittgenstein’s later philosophy argues, on behalf of Wittgenstein, that there can be no fact of the matter as to what a speaker means by her words, that is, no fact that can meet the Constitution Demand and the Normativity Demand. He particularly argues against the dispositional view, according to which meaning facts are constituted by facts about the speaker's dispositions to respond in a certain way on certain occasions. He argues that facts about dispositions (...) are finite and are incapable of constituting facts about what speakers mean by their words; they are also essentially descriptive, not prescriptive and thus, cannot meet the Normativity Demand. Hannah Ginsborg, one of the most important contemporary philosophers of language, has recently attempted to resist Kripke’s Wittgenstein’s arguments against by defending a new sort of reductive dispositionalism which can meet both demands at the same time. In this paper, I will argue that she would not be successful in her project. (shrink)

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.

Some experts have argued that patients should routinely be told the specific magnitude and absolute probability of potential risks and benefits of screening tests. This position is motivated by the idea that framing risk information in ways that are less precise violates the ethical principle of respect for autonomy and its application in informed consent or shared decisionmaking. In this Perspective, we consider a number of problems with this view that have not been adequately addressed. The most important challenges stem (...) from the danger that patients will misunderstand the information or have irrational responses to it. Any initiative in this area should take such factors into account and should consider carefully how to apply the ethical principles of respect for autonomy and beneficence. (shrink)

In the present article, I show that sounds are properties that are not physical in a narrow sense. First, I argue that sounds are properties using Moorean style arguments and defend this property view from various arguments against it that make use of salient disanalogies between sounds and colors. The first disanalogy is that we talk of objects making sounds but not of objects making colors. The second is that we count and quantify over sounds but not colors. The third (...) is that sounds can survive qualitative change in their auditory properties, but colors cannot survive change in their chromatic properties. Next, I provide a taxonomy of property views of sound. As the property view of sound has been so rarely discussed, many of the views available have never been articulated. My taxonomy will articulate these views and how they are related to one another. I taxonomize sounds according to three characteristics: dispositional/non-dispositional, relational/non-relational, and reductive/non-reductive. Finally, mirroring a popular argument in the color literature, I argue that physical views in the narrow sense are unable to accommodate the similarity and difference relations in which sounds essentially stand. I end replying to three objections. (shrink)

Naturalism has typically been entangled with a physicalist view. Physicalism, on the other hand, falls short of accounting for qualitative states of mental phenomena. The hard problem of consciousness seems to be a natural epistemic boundary in such a way that we do not even have any conceptualization as to how we can possibly account for mental states in physicalist terms in the future, which leads us to some version of causal/ontological plurality in the sense that it does not seem (...) possible to explain everything with the same parameters even though the world fundamentally consists in a single substance. If plurality in multiple levels of scientific explanation is necessary, I argue that strong emergentism is, as a metaphysical framework, the best candidate to account for this fact. I will tackle two major physicalist views by Kim and Sider. Kim shows us that non-reductive physicalism is a bankrupt project whereas Sider’s physicalism that postulates a pure and complete fundamental level renders higher-level phenomena (including mental reality) metaphysically spurious. In relation to Kim and Sider’s accounts, I will try to elaborate on my view that physicalism, when pursued to the end, is inherently reductive and ultimately falls short of accounting for the mental reality. I emphasize that the causal identification of brain and mind rests on an arbitrary carving of world, namely a description of the world which cannot be intrinsic to nature. These are the main reasons why I conclude that our revised naturalism should be disentangled from physicalism and embrace the causal/ontological plurality of strong emergentism without falling for substance dualism.

The philosophy by Husserl has always been a very interesting topic for cognitive scientists. Indeed, there is a strong analogy between the method of phenomenological reduction and the theories of mind developed by cognitive science in the last fifty years. The method of reduction is based on the concept of reality as a product of mind. Cognitive science seems to agree with this view but it is still difficult to elaborate a cognitive interpretation of the Husserl phenomenology which is philosophically (...) correct. The best attempt is that by Francisco Varela; thanks to the philosophic teaching of Humberto Maturana, he offers us a terribly reliable and audacious interpretation of Husserl even if complex for the role which plays between two necessities: the former is to construct neurophenomenology emphasizing the philosophy of Husserl like the only conceptual architecture able to study experience directly and the latter (which) is to found the enactive paradigm for cognitive science referring to Buddhist psychology.

Dedication: I would like to dedicate this essay to Mort Morehouse, whose intelligence, warmth, and good humour sustains NAACI to this day. I would like, too, to dedicate this essay to Nadia Kennedy who, in her paper “Respecting the Complexity of CI,” suggests that respect for the rich non-reductive emergent memories and understandings that evolve out of participating in the sort of complex communicative interactions that we experienced at the 2012 NAACI conference requires “a turning around and looking back (...) so that we might understand it better.” Thus, though “we cannot grasp the essence of the system in some determinate way, since each description provides a limited view, and portrays some aspect of the system from a specific position inside or outside it, and at a specific point in time,” nonetheless respect requires that we try “to take different ‘snapshots’ of such systems and attempt to make sense of them.” It is as a result of this urging that the following snapshot was attempted. My thanks to Nadia for being such an inspiration, and to all the participants for making this conference such a memorable occasion. (shrink)

In this paper I consider Kendall Walton’s provocative views on the visual arts, including his approaches to understanding both figurative and nonfigurative painting. I introduce his central notion of fictionality, illustrating its advantages in explaining the phenomenon of ‘perceptual twofoldness’. I argue that Walton’s position treats abstract artwork reductively, and I outline two essential components of our aesthetic encounters with the nonfigurative that Walton excludes. I then offer some criticisms of his commitment to photographic realism, emphasising its theoretical inconsistencies (...) with his account of representation. My own proposal is that in our apprehension of non-figurative artworks, our attention is drawn to the underlying structures of both emotive and perceptual experience. In this way, paintings, particularly abstract ones, disclose human cognition in a manner that makes fictionality an inappropriate tool for their analysis. (shrink)

Globalization is regarded as a process or a project or a process/project which is most rapidly developing. Globalization, in case of occurrence, will put its impacts on all dimensions of human life including knowledge and practice. Particularly, its impact on epistemology and education would be remarkable. Given that the appearance and development of informational revolution is the most important background for globalization, the first challenge of globalization relates to the nature of knowledge. According to the information revolution, the most important (...) characteristic of knowledge is to be sought in this equation: knowledge = information. This involves reducing different facets of knowledge to quantitative information which leads to knowledge legitimacy crisis. In addition, having a communicational dimension, knowledge will be qualified by means of the shape and characteristics of community in the era of globalization. The viewpoint of virtual community calls us from another side to rethink on knowledge as well as on the problem of identity because in the consequence of virtual community, virtual identity of pupils is being claimed which involves indentity fragmentation. To deal with these challenges, education needs: a) to resist the reduction of knowledge to information and equate knowledge with wisdom rather than information; b) to extend imaginative and creative procedures; c) to develope interdisciplinary studies as an important way of extending imagination; and finally, d) to provide relationship between virtual and real communities of the pupils.

Dretske makes arguments in which he suggests three levels of the intentionality of knowledge: (1) a low level belonging to law-like causal relationships between physical properties, (2) a middle level defined in terms of the intensionality of sentences describing knowledge of these properties, and (3) a highest level of human cognition. Acknowledging the need to explain humans’ analytic knowledge, however, he proposes that we know a proposition P analytically when we know that P entails Q, even though P and Q (...) are not identical. -/- I explore examples of deduction involving properties of every-day life, such as being a bachelor, being a stay-at-home mom, and being a consultant. I argue that to make these common sense inferences, the average person has to be aware of both analytical entailments and propositional entailments. While the former simply is knowing that if Emily is a stay-at-home mom, then Emily is female, for example, the latter requires us to be conscious of the (often complex) logical structure given to our beliefs by the deductive connectives AND, NOT, and OR. From an empirical standpoint, there are two general possibilities for reductive accounts of these kinds of awareness. One would be a counterfactually defined set of causal criteria, such as Dretske’s. The other would involve statistical patterns of synaptic connections between neural phenomena, whose firings represent our concepts for AND, NOT, and OR. I argue that neither of these reductive explanations is viable; and that in order to explain the success of our inferences, we must appeal to two kinds of higher cognitive intentionality. First, we usually have some conscious awareness of analytical and propositional entailments when we engage in common sense-based deduction. Second, we often have a conscious intention to think deductively during these inferences, which drives our success. (shrink)

Reasons are considerations that figure in sound reasoning. This is considered by many philosophers to be little more than a platitude. I argue that it actually has surprising and far-reaching metanormative implications. The view that reasons are linked to sound reasoning seems platitudinous only because we tend to assume that soundness is a normative property, in which case the view merely relates one normative phenomenon (reasons) to another (soundness). I argue that soundness is also a descriptive phenomenon, one we can (...) pick out with purely descriptive terms, and that the connection between normative reasons and sound reasoning therefore provides the basis for a reductive account of reasons. Like all proposed reductions, this one must confront some version of G. E. Moore’s open question argument. I argue that a reductive view rooted in the idea that reasons figure in sound reasoning is well-equipped to meet the open question challenge head on. (shrink)

This chapter analyzes several key themes in Kant’s views about modality. We begin with the pre-critical Only Possible Argument in Support of a Demonstration of the Existence of God, in which Kant distinguishes between formal and material elements of possibility, claims that all possibility requires an actual ground, and argues for the existence of a single necessary being. We then briefly consider how Kant’s views change in his mature period, especially concerning the role of form and thought in (...) defining modality. Kant’s mature views, however, present two difficult interpretive puzzles. The first puzzle concerns whether Kant has a generally reductive view of modality. While Kant’s views on logical modality, the role of actuality in grounding possibility, and the relation of modality to cognition all suggest reduction, we argue that the categorial status of modal concepts and the difficulty in even identifying amodal grounds for modal facts all suggest a non-reductive view. The second puzzle concerns whether Kant accepts modal facts or properties at the noumenal level. While Kant’s appeal to noumenal necessary connections, the contingency of noumenal willing, and the idea of a necessary noumenal being suggest that he endorses noumenal modality, his claims that modal concepts express only relations to the faculty of cognition and his claim that modal concepts arise from our distinctive psychological structures, we argue, suggest that he rejects noumenal modality. We conclude by considering potential solutions to these puzzles. (shrink)

A simple reductive view of intuition holds that intuition is a type of belief. That an agent who intuits that p sometimes believes that p is false is often thought to demonstrate that the simple reductive view is false. I show that this argument is inconclusive, but also that an argument for the same conclusion can be rebuilt using the notion of rational criticisability. I then use that notion to argue that perception is also not reducible to belief, (...) and that neither intuition nor perception is reducible to credence. (shrink)

This paper sets out an account of trust in AI as a relationship between clinicians, AI applications, and AI practitioners in which AI is given discretionary authority over medical questions by clinicians. Compared to other accounts in recent literature, this account more adequately explains the normative commitments created by practitioners when inviting clinicians’ trust in AI. To avoid committing to an account of trust in AI applications themselves, I sketch a reductive view on which discretionary authority is exercised by (...) AI practitioners through the vehicle of an AI application. I conclude with four critical questions based on the discretionary account to determine if trust in particular AI applications is sound, and a brief discussion of the possibility that the main roles of the physician could be replaced by AI.

Functionalism is the view that being x is to play the role of x. This paper defends a functionalist account of three-dimensional entities in the context of Wave Function Realism (WFR), that can explain in detail how we can recover three-dimensional entities out of the wavefunction. In particular, the essay advocates for a novel version of WFR in terms of a functional reductionist approach in the style of David Lewis. This account entails reduction of the upper entities to the bottom (...) ones, when the latter behave appropriately. As applied to WFR, it shows how the wavefunction can turn out to be identical to three-dimensional objects, provided certain conditions. The first major goal of the paper is thus to put forward an improved and more rigorous version of WFR, which dissolves several extant issues about the theory, and can serve as a starting point for future literature on the topic. Moreover, the second major goal of the article is to take WFR as a case study to demonstrate the pros of functional reductionism, especially in the form defended here, thereby helping to bring this view back in the philosophy of science debate. The positive upshots of this paper suggest a possible application of functional reductionism also to other contexts. (shrink)

I argue that Stroud's nonreductionism about meaning is insufficiently motivated. First, given that he rejects the assumption that grasp of an expression's meaning guides or instructs us in its use, he has no reason to accept Kripke's arguments against dispositionalism or related reductive views. Second, his argument that reductive views are impossible because they attempt to explain language “from outside” rests on an equivocation between two senses in which an explanation of language can be from outside (...) language. I offer a partially reductive account of meaning which appeals both to speakers’ dispositions to produce and respond to utterances in naturalistically specifiable ways, and to the normative attitudes they adopt, in so doing, to their own behavior. This account is supported, I argue, by Stroud's early treatment of Wittgenstein's rule-following considerations and in particular of the agreement in primitive judgments or reactions which Wittgenstein takes to be required for linguistic communication.

The standard event-causal theory of action says that an intentional action is caused in the right way by the right mental states. This view requires reductionism about agency. The causal role of the agent must be nothing over and above the causal contribution of the relevant mental event-causal processes. But commonsense finds this reductive solution to the “agent-mind problem”, the problem of explaining the relationship between agents and the mind, incredible. Where did the agent go? This paper suggests that (...) this challenge against event-causal reductionism is importantly related to debates about fundamentality. It also suggests that extant event-causal answers to the agent-mind problem, ones that suggest that part of an agent’s mind can stand proxy for the agent herself, fail against the challenge. It sketches an alternative reductive view that appeals to entity grounding. This view resolves the commonsense challenge and promises to be theoretically fruitful with respect to other longstanding problems with the event-casual view. The paper concludes with a burden-shifting argument against emergentist agent-causal theories and non-reductive event-causal theories of agency. (shrink)

Non-reductive physicalists hold that mental properties are realized by physical properties. The realization relation is typically taken to be a metaphysical necessitation relation. Here, I explore how the metaphysical necessitation feature of realization can be explained by what is known as ‘the subset view’ of realization. The subset view holds that the causal powers that are associated with a realized property are a proper subset of the causal powers that are associated with the realizer property. I argue that the (...) said explanation of the metaphysical necessitation feature requires a careful treatment of the relationship between properties and causal powers. (shrink)

Given a subject so imbued with contention and conflicting theoretical stances, it is remarkable that automated instruments ever came to replace the human eye as sensitive arbiters of color specification. Yet, dramatic shifts in assumptions and practice did occur in the first half of the twentieth century. How and why was confidence transferred from careful observers to mechanized devices when the property being measured – color – had become so closely identified with human physiology and psychology? A fertile perspective on (...) the problem is via the history of science and technology, paying particular attention to social groups and disciplinary identity to determine how those factors affected their communities’ cognitive territory. There were both common and discordant threads motivating the various technical groups that took on the problems of measuring light and color from the late nineteenth century onwards, and leading them towards the development of appropriate instruments for themselves. The transition from visual to photoelectric methods could be portrayed as a natural evolution, replacing the eye by an alternative roviding more sensitivity and convenience – indeed, this is the conventional positivist view propounded by technical histories. However, the adoption of new measurement technologies seldom is simple, and frequently has a significant cultural component. Beneath this slide towards automation lay a raft of implicit assumptions about objectivity, the nature of the observer, the role of instruments, and the trade-offs between standardization and descriptive power. While espousing rational arguments for a physical detector of color, its proponents weighted their views with tacit considerations. The reassignment of trust from the eye to automated instruments was influenced as much by the historical context as by intellectual factors. I will argue that several distinct aspects were involved, which include the reductive view of color provided by the trichromatic theory; the impetus provided by its association with photometry; the expanding mood for a quantitative and objective approach to scientific observation; and, the pressures for commercial standardization. As suggested by these factors, there was another shift of authority at play: from one technical specialism to another. The regularization of color involved appropriation of the subject by a particular set of social interests: communities of physicists and engineers espousing a ‘physicalist’ interpretation, rather than psychologists and physiologists for whom color was conceived as a more complex phenomenon. Moreover, the sources for automated color measurement, and instrumentation for measuring color, were primarily from the industrial sphere rather than from academic science. To understand these shifts, then, this chapter explores differing views of the importance of observers, machines and automation. (shrink)

In this paper I argue that Tyler Burge's non-reductive view of testiomonial knowledge cannot adeqautrely discriminate between fallacious ad vericumdium appeals to expet testimony and legitimate appeals to authority.

Arguably one of the most fundamental phase shifts that occurred in the intellectual history of Western culture involved the ontological reduction of secondary qualities to primary qualities. To say the least, this reduction worked to undermine the foundations undergirding Aristotelian thought in support of a scientific view of the world based strictly on an examination of the real—primary— qualities of things. In this essay, I identify the so-called “Causal Argument” for a reductive view of secondary qualities and seek to (...) deflect this challenge by deriving some plausible consequences that support a non-reductive view of secondary qualities from an Aristotelian view (via the philosophical commentary of Thomas Aquinas). Specifically, my argument has two facets. First, I show that Aristotle’s view both implies recognition of the extramental existence of secondary qualities and is a prima facia natural view to take regarding the ontology of secondary qualities. Second, I show that the Causal Argument, which is thought to undermine a natural view of secondary qualities as real things, loses its bite when one examines perception in light the ontological relationship among the categories of quality, quantity and substance.

Let NNG be the claim that necessitation is necessary for grounding, and let NSG be the claim that necessitation is sufficient for grounding. The consensus view is that grounding cannot be reduced to necessitation, and this is due to the (approximately) universally-accepted claim that NSG is false. Among deniers of NSG: grounding contingentists think NNG is also false, but they are in the minority compared to grounding necessitarians who uphold NNG. For one who would defend the claim that grounding is (...) reducible to necessitation, the task is formidable: she must defend NSG and NNG. I consider two prominent objections against NSG, and two more against NNG before developing a reductive account of grounding as minimal necessitation that avoids not only all four of the previously mentioned objections, but also an additional objection that targets minimal necessitation accounts in particular. If my arguments are compelling, then, insofar as we thereby have a strong prima facie case for thinking that grounding can be reduced to (minimal) necessitation, we have a strong prima facie case for thinking the consensus view is mistaken.

It is often said that normative properties are “just too different” to reduce to other kinds of properties. This suggests that many philosophers find it difficult to believe reductive theses in ethics. I argue that the distinctiveness of the normative concepts we use in thinking about reductive theses offers a more promising explanation of this psychological phenomenon than the falsity of Reductive Realism. To identify the distinctiveness of normative concepts, I use resources from familiar Hybrid views (...) of normative language and thought to develop a Hybrid view of normative concepts. In addition to using this new Hybrid view to explain why reductive theses are difficult to believe, I show how to preserve several patterns of inference involving normative concepts that, intuitively, it is possible to make, and hence answer an important recent challenge to Hybrid views from Mark Schroeder.

This paper describes a version of type identity physicalism, which we call Flat Physicalism, and shows how it meets several objections often raised against identity theories. This identity theory is informed by recent results in the conceptual foundations of physics, and in particular clar- ifies the notion of ‘physical kinds’ in light of a conceptual analysis of the paradigmatic case of reducing thermody- namics to statistical mechanics. We show how Flat Physi- calism is compatible with the appearance of multiple realisation (...) in the special sciences, and how and in what sense the special sciences laws are autonomous from the laws of physics, despite the full reductive picture of Flat Physicalism. We compare our view with a recent proposal by William Bechtel that accounts for the appearance of levels in mechanistic explanations. (shrink)

Recently, Kit Fine's (1994) view that modal truths aretrue in virtue of,grounded in, orexplained byessentialist truths has been under attack. In what follows we offer two responses to the wave of criticism against his view. While the first response is pretty straightforward, the second is based on the distinction between, what we call,Reductive Finean EssentialismandNon-Reductive Finean Essentialism. Engaging the work of Bob Hale onNon-Reductive Finean Essentialism, we aim to show that the arguments against Fine's view are unconvincing, (...) while we acknowledge the presence of a deep standoff between the two views.

This paper argues that the “Canberra Plan” picture of physicalistic reduction of mind--a picture shared by both its proponents and opponents, philosophers as diverse as David Armstrong, David Chalmers Frank Jackson, Jaegwon Kim, Joe Levine and David Lewis--neglects ground (Fine, 2001, 2012). To the extent that the point of view endorsed by the Canberra Plan has an account of the physical/functional ground of mind at all, it is in one version trivial and in another version implausible. In its most general (...) form, the point of view of the Canberra Plan is committed to unacceptably treating indexical or name-related facts as part of the ultimate physical/functional ground of the mental.

The reduction of grounding to causation, or each to a more general relation of which they are species, has sometimes been justified by the impressive inferential capacity of structural equation modelling, causal Bayes nets, and interventionist causal modelling. Many criticisms of this assimilation focus on how causation is inadequate for grounding. Here, I examine the other direction: how treating grounding in the image of causation makes the resulting view worse for causation. The distinctive features of causal modelling that make this (...) connection appealing are distorted beyond use by forcing them to fit onto grounding. The very inferential strength that makes causation attractive is only possible because of a narrow construal of what counts as a causal relation; as soon as that broadens, the inferential capacity markedly diminishes. Making causation suitable for application to grounding spoils what was appealing about causation for this task in the first place. However, grounding need not appeal to causation: causal modelling does not have exclusive claim to structural equation modeling or other formal techniques of modelling structure. I offer a case in favour of a different kind of metaphysical frugality, which tend towards narrow, more restrictive construals of relations like causation or grounding, because then each relation behaves more homogenously. This more homogenous behavior delivers stronger inferential power per relation even though there may be more relations to which one is committed. (shrink)

The identity theory’s rise to prominence in analytic philosophy of mind during the late 1950s and early 1960s is widely seen as a watershed in the development of physicalism, in the sense that whereas logical behaviourism proposed analytic and a priori ascertainable identities between the meanings of mental and physical-behavioural concepts, the identity theory proposed synthetic and a posteriori knowable identities between mental and physical properties. While this watershed does exist, the standard account of it is misleading, as it is (...) founded in erroneous intensional misreadings of the logical positivists’—especially Carnap’s—extensional notions of translation and meaning, as well as misinterpretations of the positivists’ shift from the strong thesis of translation-physicalism to the weaker and more liberal notion of reduction-physicalism that occurred in the Unity of Science programme. After setting the historical record straight, the essay traces the first truly modern identity theory to Schlick’s pre-positivist views circa 1920 and goes on to explore its further development in Feigl, arguing that the fundamental difference between the Schlick-Feigl identity theory and the more familiar and influential Place-Smart-Armstrong identity theory has resurfaced in the deep and seemingly unbridgeable gulf in contemporary philosophy of consciousness between inflationary mentalism and deflationary physicalism.
