Do conceivability arguments work against physicalism if properties are causal powers? By considering three different ways of understanding causal powers and the modality associated with them, I will argue that most, if not all, physicalist powers theorists should not be concerned about the conceivability argument because its conclusion that physicalism is false does not hold in their favoured ontology. I also defend specific powers theories against some recent objections to this strategy, arguing that the conception of properties as powerful blocks (...) conceivability arguments unless a rather implausible form of emergence is true.

This paper investigates interactive kinds, a class of kinds suggested by Ian Hacking for which classification generates a feedback loop between the classifiers and what is classified, and argues that human interactive kinds should be distinguished from non-human ones. First, I challenge the claim that there is nothing ontologically special about interactive kinds in virtue of their members being classified as such. To do so, I reject Cooper’s counterexample to Hacking’s thesis that kind descriptions are necessary for intentional action, arguing (...) that classification is required for intentional action. Having considered ways to characterise the metaphysics of interactive kinds and the semantics of kind terms, I argue that the fact that classification facilitates intentional action makes human interactive kinds ontologically distinctive because of the anomalous nature of the change which the kind-classification brings about. I then briefly examine further distinguishing features of human interactive kinds. (shrink)

In her recent paper ‘The Epistemology of Propaganda’ Rachel McKinnon discusses what she refers to as ‘TERF propaganda’. We take issue with three points in her paper. The first is her rejection of the claim that ‘TERF’ is a misogynistic slur. The second is the examples she presents as commitments of so-called ‘TERFs’, in order to establish that radical (and gender critical) feminists rely on a flawed ideology. The third is her claim that standpoint epistemology can be used to establish (...) that such feminists are wrong to worry about a threat of male violence in relation to trans women. In Section 1 we argue that ‘TERF’ is not a merely descriptive term; that to the extent that McKinnon offers considerations in support of the claim that ‘TERF’ is not a slur, these considerations fail; and that ‘TERF’ is a slur according to several prominent accounts in the contemporary literature. In Section 2, we argue that McKinnon misrepresents the position of gender critical feminists, and in doing so fails to establish the claim that the ideology behind these positions is flawed. In Section 3 we argue that McKinnon’s criticism of Stanley fails, and one implication of this is that those she characterizes as ‘positively privileged’ cannot rely on the standpoint-relative knowledge of those she characterizes as ‘negatively privileged’. We also emphasize in this section McKinnon’s failure to understand and account for multiple axes of oppression, of which the cis/trans axis is only one. (shrink)

This paper contrasts two metaphysical accounts of modality and properties: Modal Realism which treats possible entities as primitive; and Strong Dispositionalism in which metaphysical possibility and necessity are determined by actually existing dispositions or powers. I argue that Strong Dispositionalism loses its initial advantages of simplicity and parsimony over Modal Realism as it is extended and amended to account for metaphysical rather than just causal necessity. Furthermore, to avoid objections to its material and formal adequacy, Strong Dispositionalism requires a richer (...) fundamental ontology which it cannot explicate without appealing either to possible worlds or to an account of counterfactual truth conditions, both of which Strong Dispositionalism was intended to replace.

ABSTRACTMetaphysics has a problem with plurality: in many areas of discourse, there are too many good theories, rather than just one. This embarrassment of riches is a particular problem for metaphysical realists who want metaphysics to tell us the way the world is and for whom one theory is the correct one. A recent suggestion is that we can treat the different theories as being functionally or explanatorily equivalent to each other, even though they differ in content. The aim of (...) this paper is to explore whether the notion of functionally equivalent theories can be extended and utilized in the defence of metaphysical realism, drawing upon themes from structuralism in the philosophies of mathematics and science in which the specifics of theories do not matter as long as the relations in which they stand to other theories are maintained. I argue that despite its initial attractiveness, there are significant difficulties with this proposal. Discovering these obstacles thwarts the realist structuralist project, but reveals interesting features of metaphysical systems. (shrink)

It is commonly believed that Quine's principal argument for the Indeterminacy of Translation requires an untenably strong account of the underdetermination of theories by evidence, namely that that two theories may be compatible with all possible evidence for them and yet incompatible with each other. In this article, I argue that Quine's conclusion that translation is indeterminate can be based upon the weaker, uncontroversial conception of theoretical underdetermination, in conjunction with a weak reading of the ‘Gavagai’ argument which establishes the (...) underdetermination of the sense and reference of subsentential terms. If underdetermination is considered to be a widespread phenomenon in science, or in inductive reasoning more generally, then the Indeterminacy of Translation will be widespread too. Finally, I briefly consider two issues concerning the scope of this conclusion about the Indeterminacy of Translation: first, whether the argument presupposes behaviourism; and second, whether indeterminacy is restricted to the case of radical translation. I argue that the answer to both these questions is negative, and thus that the thesis of semantic indeterminacy remains relevant to those who disagree with Quine about some issues concerning the nature of mind and language.

Can metaphysics ever really be compatible with science? In this paper, I investigate the implications of the methodological approach to metaphysical theorizing known as naturalized metaphysics. In the past, metaphysics has been rejected entirely by empirically-minded philosophers as being too open to speculation and for relying on methods which are not conducive to truth. But naturalized metaphysics aims to be a less radical solution to these difficulties, treating metaphysical theorizing as being continuous with science and restricting metaphysical methods to empirically (...) respectable ones. I investigate a significant difficulty for naturalized metaphysics: that it lacks the methodological resources to comparatively evaluate competing ontological theories, or even to distinguish adequately between them. This objection is more acute when applied to robust realist versions of naturalized metaphysics, since the realist should be able to say which theory is true of the objective world. If this objection holds, then it seems that the commitment to naturalized metaphysics, or to robust realism about the categories and processes in metaphysics, will have to be relaxed. (shrink)

This paper investigates the plausibility of Witmer, Butchard and Trogdon’s proposal to distinguish intrinsic properties from extrinsic ones in terms of independence from accompaniment and grounding. I argue that the proposed criterion is not adequate to determine intrinsicality, since according to it some intuitively extrinsic properties turn out to be intrinsic. I suggest and evaluate two responses: first, one could characterize a conception of independence which is specific to the individual instantiating the property; and second, one could justify two assumptions (...) about properties which entail that counterexample properties of the kinds I present do not exist, most importantly that there are no fundamental properties which are instantiated in an intrinsic fashion by some individuals and an extrinsic fashion by others. Although the latter seems prima facie plausible, I present some potential counterexamples to it from current physical theory. I conclude that the grounding- and independence-based criterion of intrinsicality can be defended from my objections, although the cost of doing so might make it more attractive to characterize intrinsicality in terms of independence, or in terms of grounding, alone.

A significant ontological commitment is required to sustain metaphysical realism—the view that there is a single, objective way the world is—in order to defend it from common sense objections. This involves presupposing the existence of properties (or tropes, or universals) and relations between them which define the objective structure of the world. This paper explores the grounds for accepting this ontological assumption and examines a sceptical argument which questions whether, having assumed the world is objectively divided into fundamental properties, we (...) could ever know which properties these are. It then assesses the responses available to the metaphysical realist, arguing that the sceptical difficulty cannot merely be dismissed by means of another assumption in the manner of radical scepticism, as David Lewis suggests, but that the sceptic's argument might be defused by the non-question-begging success of some form of strong scientific realism which links the predicates of our scientific theories directly to the fundamental properties the world contains. It remains unclear however whether this widely accepted metaphysical theory can find principled philosophical support. (shrink)

In his conceivability argument, Chalmers assumes that all properties have their causal powers contingently and causal laws are also contingent. We argue that this claim conflicts with how conceivability itself must work for the conceivability argument to be successful. If conceivability is to be an effective mechanism to determine possibility, it must work as a matter of necessity, since contingent conceivability renders conceivability fallible for an ideal reasoner and the fallible conceivability of zombies would not entail their possibility. But necessary (...) conceivability must either be governed by necessitating causal processes or by a necessitating non-causal mechanism. We argue that the latter option is untenable or mysterious; whereas, if Chalmers chooses the former and applies it only to conceivability, his solution is ad hoc, but if he accepts necessary causal powers or processes generally, the conceivability argument fails. We conclude that, as it stands, the Conceivability Argument does not establish that physicalism is false. (shrink)

The aim of this paper will be to show that certain strongly realist forms of scientific realism are either misguided or misnamed. I will argue that, in the case of a range of robustly realist formulations of scientific realism, the ‘scientific’ and the ‘realism’ are in significant philosophical and methodological conflict with each other; in particular, that there is a tension between the actual subject matter and methods of science on the one hand, and the realists' metaphysical claims about which (...) categories of entities the world contains on the other.

_ Causal Powers _By JacobsJonathan D.Oxford University Press, 2017. xii + 232 pp.

This paper concerns the conjunction of naturalism---the thesis that the methods of science, and those alone, provide the basic sources of evidence of what there is in the world-with various types of realism. First, I distinguish different forms of naturalist realism on the basis of their ontological commitments in terms of five existential presuppositions about the entities and processes which exist independently of the mind. I then argue that some of these presuppositions are in prima facie conflict with the naturalists’ (...) endorsement of the methods of science, since certain current empirical theories could not be true if these metaphysical presuppositions are correct. Given that these ontological presuppositions have already been criticized by antirealists and supernaturalists on philosophical grounds, I suggest that realism may be more defensible from a naturalist perspective if the realist abandons, or remains agnostic about the truth of the problematic presuppositions and thereby minimizes commitment to mind-independent entities.

This volume, edited by a philosopher and an anthropologist, is a collection of essays on the philosophical implications of laboratory and field research. While neither the best nor the worst of the genre, it is a collection that offers a representative sample of traditional themes. As practicing scientists who view the implications of behavioural research from a somewhat different perspective we offer this critical review.

Many philosophers believe that there is a causal condition on perception, and that this condition is a conceptual truth about perception. A highly influential argument for this claim is based on intuitive responses to Gricean style thought experiments. Do the folk share the intuitions of philosophers? Roberts et al. (2016) presented participants with two kinds of cases: Blocker cases (similar to Grice’s case involving a mirror and a pillar) and Non-Blocker cases (similar to Grice’s case involving a clock and brain (...) stimulation). They found that a substantial minority agreed that seeing occurs in the Non-Blocker cases, and that in the Blocker cases significantly less agreed that seeing occurs. They thus hypothesized that folk intuitions better align with a no blocker condition than with a causal condition. This paper continues this line of enquiry with two new experiments. The paper investigates the generality and robustness of Roberts et al.’s findings by expanding the sense modalities tested from only vision to audition and olfaction as well. The paper also uses Gricean style thought experiments as a case study for investigating the “reflection defense” against the negative project in experimental philosophy. Our results replicate and extend Roberts et al.’s study and support their hypothesis that folk intuitions better align with a no blocker condition. They also provide an empirical reason to doubt the reflection defense. (shrink)

Sound comparative psychology and modern evolutionary and developmental biology emphasize powerful effects of developmental conditions on the expression of genetic endowment. Both demand that evolutionary theorists recognize these effects. Sound comparative psychology also demands experimental procedures that prevent experimenters from shaping the responses of human and nonhuman beings to conform to theoretical expectations.

In this article I examine the origins and progression of the practice of vivisection in roughly the first half of the sixteenth century, paying particular attention to the types of vivisection procedures performed, the classical sources for those procedures and the changing nature of the concerns motivating the anatomists who performed them. My goal is to reexamine a procedure typically treated as something revived by Vesalius from classical sources as a precursor to early modern discoveries by placing the practice of (...) vivisection in its sixteenth-century context. There were a variety of reasons for employing vivisection in the sixteenth century, including exploring the differences between living and dead bodies, considering how parts of the body worked, and advocating the entirely new idea of the pulmonary transit. By exploring the discussions of Berengario, Niccolò Massa, Vesalius, Colombo and Juan Valverde I try to elaborate on these various reasons and their origins. (shrink)

Merker's fine article opens a new view of brain function consistent with current developments in robotics, heuristics, and fuzzy logic. A reciprocal, tripartite organization of input/motivation/output in the midbrain can accomplish the practical tasks of a brain. A bold move places consciousness in the midbrain, raising profound questions about the practical nature of consciousness. (Published Online May 1 2007).

Sound comparative psychology and modern evolutionary and developmental biology (often called evo-devo) emphasize powerful effects of developmental conditions on the expression of genetic endowment. Both demand that evolutionary theorists recognize these effects. Instead, Tomasello et al. compares studies of normal human children with studies of chimpanzees reared and maintained in cognitively deprived conditions, while ignoring studies of chimpanzees in cognitively appropriate environments.

A realistic developmental view of language acquisition recognizes vocabulary and pragmatics as well as grammar with a lengthy period of growth in a favorable environment. Cross-fostering is a tool of behavioral biology for studying the interaction between genetic endowment and developmental environment. Sign language studies of cross-fostered chimpanzees measure development in a nearly human environment.

Ramsey et al. present an ingenious method to study behavioral novelty under field conditions within relatively narrow time constraints. This evokes discussion of lateral spread of innovation from individual to individual versus vertical spread from generation to generation. This discussion of incipient culture helps to place the traditional biological tool of cross-fostering into philosophical and anthropological context.

The target article issues a stirring call for more appropriate treatment of chimpanzees in experimental laboratories. This commentary heartily endorses that position with examples of methods and results found in sign language studies of cross-fostered chimpanzees.

This article, the first of a two-part study of the Chomskyan revolution, charts the initial stages of Chomsky’s success. His proposals in Syntactic Structures were very attractive to linguists in the then-dominant program. In particular, Bloomfieldianism had difficulty with syntax, and the transformation was seen as advancing linguistics in that direction; Bloomfieldianism had largely avoided semantics, and the transformation promised new ways to address meaning; and, on a metatheoretical level, the Bloomfieldians were very proud of linguistics’ status as a science, (...) and Chomsky argued that grammatical modeling was much the same enterprise as theory construction in chemistry or in physics. Chomskyan transformational grammar had no trouble attracting supporters in linguistics and soon began to generate considerable interest outside as well. The second article, to be published in the summer issue of Perspectives on Science, charts the increasingly belligerent rhetoric of the Chomskyan program, rhetoric that made it clear that the aim was not to advance the current linguistic program but rather to replace it, and which therefore sparked the too-little-too-late resistance of Bloomfieldians in the early sixties.

This article, the second of a tandem study of the Chomskyan revolution (the first is in the spring issue of Perspectives on Science), charts the increasingly antagonistic rhetoric of the Chomskyan program in the late fifties and early sixties. Chomsky began emphasizing the cognitive (a.k.a. “mentalist”) aspects of his program, along with a rationalist epistemology, both of which were anathema to the Bloomfieldians. He championed an anti-Bloomfieldian approach to phonology. Further, he insisted that neither the transformation nor the semantic inroads (...) it promised could be adopted without also adopting the cognitive, rationalist framework and rejecting Bloomfieldian phonology.

Kammerer and Frankish (this issue) challenge us to expand our conception of introspection beyond neurotypical human cases. This article describes a possible 'ancillary mind' modelled on a system envisioned in Leckie's (2013) science fiction novel Ancillary Justice. The ancillary mind constitutes a borderline case between a communicating group of individuals and a single, spatially distributed mind. It occupies a grey zone with respect to personal identity and subject individuation, neither determinately one person or subject nor determinately many persons or subjects, (...) and thus some of its processes might be neither determinately introspection within a mind nor determinately communication between minds. If ancillary minds defy discrete countability, the same might be true for some actual minds on Earth. Kammerer and Frankish's research programme can be extended to include not only the study of possible forms of introspection, but also the study of possible mental activity intermediate between introspection and communication.

What determines qualitative sameness and difference? This book explores four principal accounts of the ontological basis of properties, including universals, trope theory, resemblance nominalism, and class nominalism, considering the assumptions and ontolological commitments which are required to make each into a plausible account of properties. -/- The latter half of the book investigates the applications of property theory and the different conceptions of properties which might be adopted with these in mind: first, the possibility and desirability of individuating properties, and (...) the distinction between sparse and abundant conceptions of properties; second, the distinction between intrinsic and extrinsic properties; third, the relationship between properties and their causal powers, and whether this is necessary or contingent; fourth, the relationship between properties and causation, modality, and laws of nature; finally, whether properties exist objectively, and if they do, what our epistemic position is with respect to such entities.

The adoption of the term grievance-fuelled violence reflects the fact that similarities exist between those committing violent acts in the context of grievance in different settings, so potentially allowing the application of insights gained in the study of one group to be applied to others. Given the low base rate of violence against public figures, studies in the field of violence against those in the public eye have tended to use, as a proxy for violence, attempts by the individuals concerned (...) to achieve unwarranted and unwanted proximity to the subject of their attention, given that approach is a necessary prerequisite for most forms of attack. In such studies, one factor that has frequently been considered is whether the making of threats is associated with a subsequent approach. The results have been varied, with no correlation found in some, a negative correlation in others, and a positive correlation in at least one. Such studies have been retrospective, using case files prepared for other purposes, and samples of cases have been selected according to their victims’ sector of employment – for instance, politicians, celebrities, judiciary, and the corporate world. This study of a sample of 126 threat assessment cases, using a prospective methodology, looks at the associations between the making of threats and subsequent approach from a different angle – that of a standardised and validated classification of underlying motivation. It finds that particular types and forms of threat are significantly associated with subsequent approach in cases that are fuelled by grievance, but not in those with the motivation of seeking a relationship. Furthermore, when a sample with a mixture of motivational categories was examined in the manner of previous studies, such associations with threat were not apparent. These results refine the existing understanding of the significance of threats in public-facing cases. Future research projects in this area might usefully incorporate the consideration of underlying motivation, in particular grievance. (shrink)
