In this paper I offer a unified causal account of natural kinds. Using as a starting point the widely held view that natural kind terms or predicates are projectible, I argue that the ontological bases of their projectibility are the causal properties and relations associated with the natural kinds themselves. Natural kinds are not just concatenations of properties but ordered hierarchies of properties, whose instances are related to one another as causes and effects (...) in recurrent causal processes. The resulting account of natural kinds as clusters of core causal properties that give rise to clusters of derivative properties enables us to distinguish genuine natural kinds from non-natural kinds. For instance, it enables us to say why some of the purely conventional categories derived from the social domain do not correspond to natural kinds, though other social categories may. (shrink)

Carruthers’s central project in Phenomenal Consciousness is to naturalize consciousness. Given the vast success of naturalism in science, he maintains that we should require powerful reasons to abandon it when constructing philosophical theories of consciousness. Unsurprisingly, he then argues that there are no such reasons. In particular, he claims that the well-known arguments of Thomas Nagel and Frank Jackson fail, as do inverted and absent qualia arguments. Carruthers’s main strategy for defusing these arguments involves first distinguishing a “thin” notion of (...) property from a “thick” notion of property and then arguing that the various antinaturalistic arguments conflate these two different notions. Although he admits that the antinaturalist may not find these considerations wholly convincing, he construes the dialectical situation in such a way as to relieve him of any obligation to do more. As long as it can be shown that the antinaturalistic arguments are not obviously successful, which he takes himself to have done, Carruthers claims that the presumption in favor of naturalism remains. Thus, a theory of consciousness must be compatible with the following two naturalistic claims: first, all mental events occur in accordance with causal laws; and second, all mental events can be given a reductive explanation in physical terms.

The identity of a natural kind can be construed in terms of its causal profile. This conception is more appropriate to science than two alternatives. The identity of a natural kind is not determined by one causal role because one natural kind can have many causal roles and several functions and because some functions are shared by different kinds. Furthermore, the microstructuralist thesis is wrong: The identity of certain natural kinds is not determined by (...) their microstructure. It is true that if A and B have the same microstructural composition then a sample of a chemical substance A is of the same chemical substance as a sample of B. However, the reverse does not hold. It is not the case that if a sample of a chemical substance A is of the same chemical substance as a sample of B then A and B have the same microstructural composition. This is because a macroscopic NK can be “multiconstituted” by different microstructures. (shrink)

Realist accounts of natural kinds rely on an account of causation where the relata of causal relations are real and discrete. These views about natural kinds entail very different accounts of causation. In particular, the necessity of the causal relation given the instantiation of the properties of natural kinds is more robust in the fundamental sciences (e.g. physics and chemistry) than it is in the life sciences (e.g. biology and the medical sciences). In this (...) paper, I wish to argue that there is a difference in kind between the putative natural kinds of the fundamental sciences and those of the life sciences, such that a uniform account of causation cannot capture both. The upshot is that we must either reject the claim that the kinds of the life sciences are genuine natural kinds, or accept that there are different kinds of causal relations involving the relata of natural kinds. I accept the latter. I reject the objection that the true causal relations that relate macro-level kinds are to be found by “going down a level” to causal relation at the fundamental kind, because the relevant causal mechanisms are not at the fundamental level. Since, autonomous mechanistic accounts of causal relations at the macro-level can be provided (e.g. in Biology and medicine), I argue that realism about the natural kinds of the life sciences is justified. I address the problem of negative causation as a counterexample to the positive account of causation that is entailed by realism about natural kinds in the life sciences. I argue that an acceptance of realist accounts of two different kinds of natural kind makes a uniform analysis of causation look unpromising. (277 words). (shrink)

In ‘Induction and Natural Kinds’, I proposed a solution to the problem of induction according to which our use of inductive inference is reliable because it is grounded in the natural kind structure of the world. When we infer that unobserved members of a kind will have the same properties as observed members of the kind, we are right because all members of the kind possess the same essential properties. The claim that the existence of natural (...) kinds is what grounds reliable use of induction is based on an inference to the best explanation of the success of our inductive practices. As such, the argument for the existence of natural kinds employs a form of ampliative inference. But induction is likewise a form of ampliative inference. Given both of these facts, my account of the reliability of induction is subject to the objection that it provides a circular justification of induction, since it employs an ampliative inference to justify an ampliative inference. In this paper, I respond to the objection of circularity by arguing that what justifies induction is not the inference to the best explanation of its reliability. The ground of induction is the natural kinds themselves. (shrink)

Naturalists who conceive of knowledge as a natural kind are led to treat ‘knowledge’ as a natural kind term. ‘Knowledge,’ then, must behave semantically in the ways that seem to support a direct reference theory for other natural kind terms. A direct reference theory for ‘knowledge,’ however, appears to leave open too many possibilities about the identity of knowledge. Intuitively, states of belief count as knowledge only if they meet epistemic criteria, not merely if they bear a (...) causal/historical relation to the term. I will develop this objection and show that it is grounded in modal considerations central to Kripke’s work on reference. I will also argue that a more plausible externalist semantics for natural kind terms disarms the objection. (shrink)

Philosophers have been referring to the “Kripke–Putnam” theory of naturalkind terms for over 30 years. Although there is one common starting point, the two philosophers began with different motivations and presuppositions, and developed in different ways. Putnam’s publications on the topic evolved over the decades, certainly clarifying and probably modifying his analysis, while Kripke published nothing after 1980. The result is two very different theories about natural kinds and their names. Both accept that the meaning of a naturalkind (...) term is not given by a description or defining properties, but is specified byits referents. From then on, Putnam rejected even the label, causal theory of reference, preferring to say historical, or collective. He called his own approach indexical. His account of substance identity stops short a number of objections that were later raised, such as what is called the qua problem. He came to reject the thought that water is necessarily H2O, and to denounce the idea of metaphysical necessity that goes beyond physical necessity. Essences never had a role in his analysis; there is no sense in which he was an essentialist. He thought of hidden structures as the usual determinant of natural kinds, but always insisted that what counts as a natural kind is relative to interests. “Natural kind” itself is itself an importantly theoretical concept, he argued. The paper also notes that Putnam says a great deal about what natural kinds are, while Kripke did not. Moreover, a theory about names of natural kinds is to some extent independent of a theory of natural kinds themselves, to the extent that one can accept the one and reject the other, even when both are advanced by the same philosopher.

This chapter discusses the distinction between natural kinds and natural properties. Some theorists deny the distinction, and claim that natural kinds can be identified with properties. For example, natural kinds might be understood as the perfectly natural properties, reducible to properties or the extensions of properties. Alternatively, one might argue that natural kinds and natural properties are distinct and that natural kinds could be considered as a sui (...) generis type of entity. For example, one might hold that natural kinds require a distinct kind of universal, substantival universal, or sortal. Alternatively, one might claim that properties themselves form natural kind groupings, in virtue of causal mechanisms. This chapter argues that classification into natural kinds can reflect real differences between natural groups, without the supplementary ontological distinction between properties and kinds. -/- .

Kant’s view that freedom is a “kind of causality” seems to conflict with his claim that the categories of the understanding – including causality – can only be applied objectively to sensible phaenomena, never to supersensible noumena, as freedom is only possible for the latter. I argue that only Kant’s theory of symbolic presentation, according to which the category of cause is applied merely analogically to freedom, can dispel this threatening inconsistency. Unlike it is commonly thought, one cannot (...) here use the category of cause in its unschematised form to think freedom as causality, for its mere logical significance does not suffice for the practical reality of freedom. Symbolic cognition in turn is not unschematised but indirect schematized presentation. Ultimately I will show that symbolic cognition is a necessary condition of moral agency – but not of morality itself – for without it we could not cognize and hence self-consciously use our freedom to act from the moral law.

This paper evaluates the Natural-Kinds Argument for cognitive extension, which purports to show that the kinds presupposed by our best cognitive science have instances external to human organism. Various interpretations of the argument are articulated and evaluated, using the overarching categories of memory and cognition as test cases. Particular emphasis is placed on criteria for the scientific legitimacy of generic kinds, that is, kinds characterized in very broad terms rather than in terms of their fine-grained (...) causal roles. Given the current state of cognitive science, I conclude that we have no reason to think memory or cognition are generic natural kinds that can ground an argument for cognitive extension. (shrink)

This article offers a reading of Eriugena’s thought that is inspired by Heidegger’s claim according to which being is constituted in a dialectical interplay of revelation and concealment. Beginning with an analysis of how “causality as concealing revelation” works on the level of God’s inner-Trinitarian life, the piece moves on to a consideration of the way in which the human soul reveals itself in successive stages of exteriorization that culminate in the creation of the body, its “image.” The body, (...) however, conceals as much as it reveals true human nature. Moreover, it is shown that for Eriugena all of reality, as theophany, possesses this character of concealing its fundamental truth. These insights lead Eriugena to a recognition of radical human finitude, as genuine wisdom requires an acknowledgement of our fundamental ignorance. (shrink)

The aim of this article is to illustrate how a belief in the existence of kinds may be justified for the particular case of natural kinds: particularly noteworthy in this respect is the weight borne by scientific natural kinds (e.g., physical, chemical, and biological kinds) in (i) inductive arguments; (ii) the laws of nature; and (iii) causal explanations. It is argued that biological taxa are properly viewed as kinds as well, despite the fact (...) that they have been by some alleged to be individuals. Since it turns out that the arguments associated with the standard Kripke/Putnam semantics for natural kind terms only establish the non-descriptiveness of natural kind terms and not their rigidity, the door is open to analyze these terms as denoting traditional predicate-extensions. Finally, special issues raised by physical and chemical kinds are considered briefly, in particular impurities, isotopes and the threat of incommensurability. (shrink)

Recent experimental studies have claimed to find evidence for the view that natural kind terms such as “water” are ambiguous: that they have two extensions, one determined by superficial properties, the other by underlying essence. In an online experiment, we presented to 600 participants scenarios describing discoveries of novel samples that differ in deep structure from samples of a familiar kind but are superficially identical, such as a water-like substance that is not composed of H2O. We used three different (...) types of question sets to probe whether the participants considered the sample as a member of the kind or not. Our results did not confirm the predictions of the ambiguity view. They were, rather, consistent with views that take underlying essences to be the sole criterion for membership in a natural kind.

While philosophers tend to consider a single type of causal history, biologists distinguish between two kinds of causal history: evolutionary history and developmental history. This essay studies the peculiarity of development as a criterion for the individuation of biological traits and its relation to form, function, and evolution. By focusing on examples involving serial homologies and genetic reprogramming, we argue that morphology (form) and function, even when supplemented with evolutionary history, are sometimes insufficient to individuate traits. Developmental mechanisms bring (...) in a novel aspect to the business of classification—identity of process-type—according to which entities are type-identical across individuals and natural kinds in virtue of the fact that they form and develop through similar processes. These considerations bear important metaphysical implications and have potential applications in several areas of philosophy. (shrink)

There is growing support for the view that social categories like men and women refer to “objective types” (Haslanger 2000, 2006, 2012; Alcoff 2005). An objective type is a similarity class for which the axis of similarity is an objective rather than nominal or fictional property. Such types are independently real and causally relevant, yet their unity does not derive from an essential property. Given this tandem of features, it is not surprising why empirically-minded researchers interested in fighting oppression and (...) marginalization have found this ontological category so attractive: objective types have the ontological credentials to secure the reality (and thus political representation) of social categories, and yet they do not impose exclusionary essences that also naturalize and legitimize social inequalities. This essay argues that, from the perspective of these political goals of fighting oppression and marginalization, the category of objective types is in fact a Trojan horse; it looks like a gift, but it ends up creating trouble. I argue that objective type classifications often lack empirical adequacy, and as a result they lack political adequacy. I also provide, and in reference to the normative goals described above, several arguments for preferring a social ontology of natural kinds with historical essences. (shrink)

Biological species are often taken as counterexamples to essentialist accounts of natural kinds. Essentialists like Ellis (2001) agree with nominalists that because biological kinds evolve, any distinctions between kinds of biological kind must ultimately be arbitrary. The resulting vagueness in the extension of natural kind predicates in the case of species has led to the claim that species ought to be construed as individuals rather than kinds (Ghiselin 1974, 1987; Hull 1976, 1978). I examine (...) the possibility that causal features extrinsic to the properties of natural kinds are responsible for establishing the unity of the properties of a natural kind. I reject the intuitive idea that laws of nature might act as such an external mechanism because this would entail an account of ceteris paribus biological laws, where there are no plausible truthmakers in terms of kinds or properties. I suggest instead that symbiosis is a plausible external causal mechanism, which explains the evolution of homeostasis in natural kind clusters. This involves the acceptance of an expanded account of evolutionary development as cooperative symbiosis. (shrink)

In a recent paper, Cheng and Werning (2016) argue that the class of episodic memories constitutes a natural kind. Endorsing the homeostatic property cluster view of natural kinds, they suggest that episodic memories can be characterized by a cluster of properties unified by an underlying neural mechanism for coding sequences of events. Here, I argue that Cheng & Werning’s proposal faces some significant, and potentially insurmountable, difficulties. Two are described as most prominent. First, the proposal fails to (...) satisfy an important normative constraint on natural kind theorizing, not providing the requisite theoretical resources for arbitration between rival taxonomies of memory. Second, the proposal is in a direct tension with a foundational principle of the HPC view: the rejection of essentialism. This has far-reaching consequences, threatening to undermine the coherence of the proposal. (shrink)

Plato’s invention of the metaphor of carving the world by the joints gives him a privileged place in the history of natural kind theory in philosophy and science; he is often understood to present a paradigmatic but antiquated view of natural kinds as possessing eternal, immutable, necessary essences. Yet, I highlight that, as a point of distinction from contemporary views about natural kinds, Plato subscribes to an intelligent-design, teleological framework, in which the natural world (...) is the product of craft and, as a result, is structured such that it is good for it to be that way. In Plato’s Philebus, the character Socrates introduces a method of inquiry whose articulation of natural kinds enables it to confer expert knowledge, such as literacy. My paper contributes to an understanding of Plato’s view of natural kinds by interpreting this method in light of Plato’s teleological conception of nature. I argue that a human inquirer who uses the method identifies kinds with relational essences within a system causally related to the production of some unique craft-object, such as writing. As a result, I recast Plato’s place in the history of philosophy, including Plato’s view of the relation between the kinds according to the natural and social sciences. Whereas some are inclined to separate natural from social kinds, Plato holds the unique view that all naturalness is a social feature of kinds reflecting the role of intelligent agency. (shrink)

This paper takes a hierarchical approach to the question whether species are individuals or natural kinds. The thesis defended here is that species are spatiotemporally located complex wholes (individuals), that are composed of (i.e., include) causally interdependent parts, which collectively also instantiate a homeostatic property cluster (HPC) natural kind. Species may form open or closed genetic systems that are dynamic in nature, that have fuzzy boundaries due to the processual nature of speciation, that may have leaky boundaries (...) as is manifest in lateral gene transfer and introgression, that may be of multiple origins through hybridization, and that may split and merge and split again over time. The identity conditions of species qua individuals will have to be anchored in their history, rather than in their unique evolutionary origin. Species qua historically conditioned HPC natural kinds requires the kind to be mereologically structured, subject to the part-whole relation rather than the membership relation. This implies that there can be more than one kind of natural kinds. (shrink)

In an attempt to address some long-standing issues of epistemology, Hilary Kornblith proposes that knowledge is a natural kind the identification of which is the unique responsibility of one particular science: cognitive ethology. As Kornblith sees it, the natural kind thus picked out is knowledge as construed by reliabilism. Yet the claim that cognitive ethology has this special role has not convinced all critics. The present article argues that knowledge plays a causal and explanatory role within many of (...) our more fruitful current theories, diverging from the reliabilist conception even in disciplines that are closely related to cognitive ethology, and thus still dealing with knowledge as a natural as opposed to a social phenomenon, where special attention will be given to cognitive neuroscience. However, rather than discarding the natural kind approach altogether, it is argued that many of Kornblith’s insights can in fact be preserved within a framework that is both naturalist and pluralist.

The search for a nomological account of what determines the content of concepts as they are represented in cognitive systems, is an important part of the general project of explaining intentional phenomena in naturalistic terms. I examine Fodor's "Theory of Content" and criticize his strategy of combining constraints in nomological terms with contraints in terms of actual causal relations. The paper focuses on the problem of the indeterminacy of the content of natural kind concepts. A concept like water can (...) pick out either a phenomenological property or a scientific one. Moreover, even on the assumption that the latter is shown to be most adequate, a given sample will still come out as falling into different natural kinds, according to the taxomomy of each particular science of which it constitutes an object. Both chemistry and physics contain concepts which are scientific counterparts of the common sense concept water, yet their extensions differ. As a criterion for determining the most relevant science for a given concept, I suggest to ask which science is most specific for the typical interactions of the subject possessing the concept, with her environment. The use of this criterion also permits one to show that a nomological theory is not necessarily verificationist, contrary to what has been claimed by Fodor and Boghossian. (shrink)

The psychiatric category of addiction has recently been broadened to include new behaviors. This has prompted critical discussion about the value of a concept that covers so many different substances and activities. Many of the debates surrounding the notion of addiction stem from different views concerning what kind of a thing addiction fundamentally is. In this essay, we put forward an account that conceptualizes different addictions as sharing a cluster of relevant properties (the syndrome) that is supported by a matrix (...) of causal mechanisms. According to this “addiction-as-a-kind” hypothesis, several different kinds of substance and behavioral addictions can be thought of as instantiations of the same thing – addiction. We show how a clearly articulated account of addiction can facilitate empirical research and the theoretical integration of different perspectives on addiction. The causal matrix approach provides a promising alternative to existing accounts of the nature of psychiatric disorders, the traditional disease model, and its competitors. It is a positive addition to discussions about diagnostic criteria, and sheds light on how psychiatric classification may be integrated with research done in other scientific fields. We argue that it also provides a plausible approach to understanding comorbidity. (shrink)

In this volume, leading philosophers of psychiatry examine psychiatric classification systems, including the Diagnostic and Statistical Manual of Mental Disorders, asking whether current systems are sufficient for effective diagnosis, treatment, and research. Doing so, they take up the question of whether mental disorders are natural kinds, grounded in something in the outside world. Psychiatric categories based on natural kinds should group phenomena in such a way that they are subject to the same type of causal explanations (...) and respond similarly to the same type of causal interventions. When these categories do not evince such groupings, there is reason to revise existing classifications. The contributors all question current psychiatric classifications systems and the assumptions on which they are based. They differ, however, as to why and to what extent the categories are inadequate and how to address the problem. Topics discussed include taxometric methods for identifying natural kinds, the error and bias inherent in DSM categories, and the complexities involved in classifying such specific mental disorders as "oppositional defiance disorder" and pathological gambling. -/- Contributors George Graham, Nick Haslam, Allan Horwitz, Harold Kincaid, Dominic Murphy, Jeffrey Poland, Nancy Nyquist Potter, Don Ross, Dan Stein, Jacqueline Sullivan, Serife Tekin, Peter Zachar.

Underlying much current work in philosophy of imagination is the assumption that imagination is a skill. This assumption seems to entail not only that facility with imagining will vary from one person to another, but also that people can improve their own imaginative capacities and learn to be better imaginers. This paper takes up this issue. After showing why this is properly understood as a philosophical question, I discuss what it means to say that one imagining is better than another (...) and then discuss the kinds of imagination training and techniques that might be employed in an effort to get better at imagining. The discussion of these techniques draws insight from consideration of other skills-based activities, as well as from consideration of the creation of art and our engagement with literature and poetry. Over the course of this discussion, we also gain further insight into the nature of imagination. (shrink)

How are we to understand the phenomenology of imagining? Attempts to answer this question often invoke descriptors concerning the “vivacity” or “vividness” of our imaginative states. Not only are particular imaginings often phenomenologically compared and contrasted with other imaginings on grounds of how vivid they are, but such imaginings are also often compared and contrasted with perceptions and memories on similar grounds. Yet however natural it may be to use “vividness” and cognate terms in discussions of imagination, it does (...) not take much reflection to see that these terms are ill understood. In this paper, I review both some relevant empirical literature as well as the philosophical literature attempt to get a handle on what it could mean, in an imaginative context, to talk of vividness. As I suggest, this notion ultimately proves to be so problematic as to be philosophically untenable. (shrink)

As persons, we are importantly different from all other creatures in the universe. But in what, exactly, does this difference consist? What kinds of entities are we, and what makes each of us the same person today that we were yesterday? Could we survive having all of our memories erased and replaced with false ones? What about if our bodies were destroyed and our brains were transplanted into android bodies, or if instead our minds were simply uploaded to computers?

As she shows, our intuitions on these issues often pull us in different directions, making it difficult to develop an adequate general theory.

The project of treating knowledge as an empirical object of study has gained popularity in recent naturalistic epistemology. It is argued here that the assumption that such an object of study exists is in tension with other central elements of naturalistic philosophy. Two hypotheses are considered. In the first, “knowledge” is hypothesized to refer to mental states causally responsible for the behaviour of cognitive agents. Here, the relational character of truth creates a problem. In the second hypothesis “knowledge” is hypothesized (...) to refer to mental states causally responsible for the evolutionarily successful behaviour of cognitive agents. Here, the problem lies in the fact that evolution by natural selection is not necessarily conducive to truth. The result does not necessarily amount to eliminativism, however, since the naturalist may consistently reject the condition of truth that lies behind these problems. (shrink)

In this Element, we’ll explore the nature of both imagination and creative thinking in an effort to understand the relation between them and also to understand their role in the vast array of activities in which they are typically implicated, from art, music, and literature to technology, medicine, and science. Focusing on the contemporary philosophical literature, we will take up several interrelated questions: What is imagination, and how does it fit into the cognitive architecture of the mind? What is creativity? (...) Is imagination required for creativity? Is creativity required for imagination? Is a person simply born either imaginative or not (and likewise, either creative or not), or are imagination and creativity skills that can be cultivated? And finally, are imagination and creativity uniquely human capacities, or can they be had by nonbiological entities such as AI systems? (shrink)

This paper addresses a philosophical problem concerning the ontological status of age classification. For various purposes, people are commonly classified into categories such as “young adulthood”, “middle adulthood”, and “older adulthood”, which are defined chronologically. These age categories prima facie seem to qualify as natural kinds under a homeostatic property cluster account of natural kindhood, insofar as they capture certain biological, psychological, and social properties of people that tend to cluster together due to causal processes. However, this (...) is challenged by the observation that age categories are historically unstable. The properties that age categories are supposed to capture are affected by healthcare and cultural developments, such that people are staying biologically, psychologically, and socially young for longer. Furthermore, the act of classifying people into age categories can bring about changes in their behaviors, which in turn alter the biological, psychological, and social properties that the categories are supposed to capture. Accordingly, I propose that age categories are best understood as interactive kinds that are influenced in dynamic ways by looping effects. I consider some implications of these looping effects for our classificatory practices concerning age, including how different disciplines may need to review the ways they define and use age categories in their inductive inferences.

Colloquially, episodic memory is described as “the memory of personally experienced events”. Even though episodic memory has been studied in psychology and neuroscience for about six decades, there is still great uncertainty as to what episodic memory is. Here we ask how episodic memory should be characterized in order to be validated as a natural kind. We propose to conceive of episodic memory as a knowledge-like state that is identified with an experientially based mnemonic representation of an episode that (...) allows for a mnemonic simulation thereof. We call our analysis the Sequence Analysis of Episodic Memory since episodes will be analyzed in terms of sequences of events. Our philosophical analysis of episodic memory is driven and supported by experimental results from psychology and neuroscience. We discuss selected experimental results that provide exemplary evidence for uniform causal mechanisms underlying the properties of episodic memory and argue that episodic memory is a natural kind. The argumentation proceeds along three cornerstones: First, psychological evidence suggests that a violation of any of the proposed conditions for episodic memory amounts to a deficiency of episodic memory and no form of memory or cognitive process but episodic memory fulfills them. Second, empirical results support a claim that the principal anatomical substrate of episodic memory is the hippocampus. Finally, we can pin down causal mechanisms onto neural activities in the hippocampus to explain the psychological states and processes constituting episodic memory. (shrink)

J. L. Mackie's famous claim that Locke ‘anticipates’ Kripke's Causal Theory of Reference rests, I suggest, upon a pair of important misunderstandings. Contra Mackie, as well as the more recent accounts of Paul Guyer and Michael Ayers, Lockean Real Essences consist of those features of an entity from which all of its experienceable properties can be logically deduced; thus a substantival Real Essence consists of features of a Real Constitution plus logically necessary objective connections between them and features of some (...) particular Nominal Essence. Furthermore, what Locke actually anticipates is the most significant contemporary challenge to the CTR: the qua‐problem. (shrink)

Innate cognitive capacities are widely posited in cognitive science, yet both philosophers and scientists have criticized the concept of innateness as being hopelessly confused. Despite a number of recent attempts to define or characterize innateness, critics have charged that it is associated with a diverse set of properties and encourages unwarranted inferences among properties that are frequently unrelated. This criticism can be countered by showing that the properties associated with innateness cluster together in reliable ways, at least in the context (...) of the study of cognition. Even though the causal connections between these cognitive properties are not always strict, they are robust enough to warrant considering innateness to be a natural kind as used in contemporary cognitive science.

Both imagery and imagination play an important part in our mental lives. This article, which has three main sections, discusses both of these phenomena, and the connection between them.

The second part turns to the faculty of the imagination, discussing the long philosophical tradition linking mental imagery and the imagination—a tradition that came under attack in the (...) early part of the twentieth century with the rise of behaviorism. Finally, the third part of this article examines modal epistemology, where the imagination has been thought to serve an important philosophical function, namely, as a guide to possibility. (shrink)

Philosophers have long suggested that our attitude of special concern for the future is problematic for a reductionist view of personal identity, such as the one developed by Derek Parfit in Reasons and Persons. Specifically, it is often claimed that reductionism cannot provide justification for this attitude. In this paper, I argue that much of the debate in this arena involves a misconception of the connection between metaphysical theories of personal identity and our special concern. A proper understanding of this (...) connection reveals that the above-mentioned objection to reductionism cannot get off the ground. Though the connection I propose is weaker than the connection typically presupposed, I nonetheless run up against a conclusion reached by Susan Wolf in “Self-Interest and Interest in Selves.” According to Wolf, metaphysical theses about the nature of personal identity have no significance for our attitude of special concern. By arguing against Wolf’s treatment of self-interest, I suggest that her arguments for this conclusion are misguided. This discussion leads to further clarification of the nature of the link between theories of personal identity and our special concern and, ultimately, to a better understanding of the rationality of this attitude.

In several early 19th century works, Mary Shepherd articulates a theory of causation that is intended to respond to Humean skepticism. I argue that Shepherd's theory should be read in light of the science of the day and her conception of her place in the British philosophical tradition. Reading Shepherd’s theory in light of her conception of the history of philosophy, including her claim to be the genuine heir of Locke, illuminates the broader significance of her attempt to reinstate reason (...) as the source of scientific knowledge. Reading Shepherd's theory in light of the science of the day helps make plausible her claim that there are robust natural kinds in nature, defined by their causal powers: this is precisely what then-recent advances in chemistry hold.

Among the many commonalities between memory and imagination is the fact that they can both be understood as skills. In this chapter, I aim to draw out some connections between the skill of memory and the skill of imagination in an effort to learn something about the nature of these activities and the connection between them. I start by considering the ways that one might work to cultivate these skills in the hope that we could learn something about imagination training (...) by reflection on memory training and vice versa. Interestingly, however, an initial look at the empirical research on the respective training regimens does not show much potential for this kind of crossover. Though there are some commonalities that can be found across the training regimens, these commonalities are nothing special over and above the kinds of commonalities one might find in training regimens for skills of any sort. Fortunately, however, the matter does not end there. When we think more deeply about the details of some of the training regimens for memory, we discover some important connections between the skill of memory and the skill of imagination. In particular, I argue that the two skills turn out to be interestingly intertwined. (shrink)

As we await the increasingly likely advent of genuinely intelligent artificial systems, a fair amount of consideration has been given to how we humans will interact with them. Less consideration has been given to how—indeed if—we humans will love them. What would human-AI romantic relationships look like? What do such relationships tell us about the nature of love? This chapter explores these questions via consideration of several works of science fiction, focusing especially on the Black Mirror episode “Be Right Back” (...) and the Spike Jonze's movie *Her*. As I suggest, there may well be cases where it is both possible and appropriate for a human to fall in love with a machine. (shrink)

Some philosophers have claimed that kinds can be construed as mereologically complex structural properties. This essay examines several strategies aimed at construing a certain class of natural kinds, namely isomeric chemical kinds, in accordance with this view. In particular, the essay examines views which posit structural proper parts in addition to micro-constitutive parts to individuate isomeric chemical kinds. It then goes on to argue that the phenomenon of chirality in stereochemistry gives the proponent of (...) class='Hi'>kinds-as-complex-properties evidence for positing the existence of causal-cum-dispositional individuating proper parts, in addition to structural parts, for chemical enantiomeric kinds.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Imagination in Inquiry by A. Pablo IannoneAmy KindIANNONE, A. Pablo. Imagination in Inquiry. Lanham, Md.: Lexington Books, 2022. xxvi + 254 pp. Cloth, $110.00; eBook $45.00Though imagination is often associated with the fanciful and the fictional, over the course of the last decade philosophers have begun to devote considerable attention to more practical uses of imagination. Philosophers of imagination have increasingly focused on ways in which imagination can (...) play an important epistemic role in activities such as decision-making, planning, and scientific discovery; more generally, there has been attention to a variety of ways in which imagination can teach us about the world in which we live. Iannone’s discussion in Imagination in Inquiry can be seen as part of this general trend—even if his discussion is not itself situated directly within contemporary philosophy of imagination but, rather, in a broader interdisciplinary approach.Iannone works with an expansive conception of what imagination is. In his view, we should not limit our understanding of imagination simply to the ability to generate images. Rather, imagination is a diverse set of different abilities that aim “at figuring out cognitively, emotively, or practically, alternatives for dealing with actual, probable, plausible, foreseeable, or merely possible challenges or problems, abstract or concrete, theoretical or practical being faced, or notions being considered, and determining or deciding which is (are) preferable in the circumstances, and acting accordingly.” Moreover, this set of abilities should not be seen as operating in isolation; rather, imagination functions as part of an ecology of human abilities. Iannone refers to his view of imagination as the “homeostatic model,” so called because he sees imaginative processes as maintaining stability by way of a system of self-correcting feedback and methods for incorporating and adjusting to any new information received.Iannone also operates with an expansive conception of what counts as practical use of imagination. In his view, imagination is put to practical use in a wide range of circumstances, for example, when a dancer imagines the next steps of a dance in the process of spontaneous improvising, when a combatant imagines how to block an expected blow from an opponent, and when an environmental activist imagines a new set of corrective policies to address pollution. All these uses fall under the activity of what Iannone calls “inquiry,” that is, the activity of finding a solution to a problem or challenge. The problems and challenges that might prompt the use of imagination can be both personal and interpersonal, and the imaginative processes used will involve strategies such as discovery, creation, and anticipation.In the first part of the book, Iannone develops his basic conceptual apparatus. In the next part of the book, he puts this apparatus to work in the context of philosophy, that is, he shows how imagination plays a role in philosophical inquiry. In the third part of the book, he looks at the role of imagination in other disciplines such as sociology and psychology. Here, the interdisciplinary nature of his discussion is especially on display. In the fourth part of the book, he applies his model of imagination to a number of different contexts; in particular, he discusses the role of [End Page 354] imagination in language, in humor, in vision (both at the personal and the societal level), and in morality. Finally, the last part of the book offers a variety of case studies involving dance, technology, and artificial intelligence. Of the four chapters in this part of the book, three are written by other authors: two by Alejandra Iannone, a scholar and practitioner of dance and theater (and the author’s daughter), and one by Rocci Luppicini, an expert in technology studies. In light of the explosive pace with which new AI technologies are being developed, the book’s discussion of whether and how such technologies present challenges for our capacity for imagination is especially timely and important.In addition to affirming the practical importance of imagination, Iannone also affirms the practical importance of nurturing imagination—something he repeats at several points throughout the book. But how do we do this? One natural way that imagination is nurtured is simply by its regular use... (shrink)

Klein's target article argues that autonoetic consciousness is a necessary condition for memory; this unusually narrow view of the scope of memory implies that only episodic memory is, strictly speaking, memory. The narrow view is opposed to the standard broad view, on which causal connection with past experience is sufficient for memory; on the broad view, both declarative (i.e., episodic and semantic) and procedural memory count as genuine forms of memory. Klein mounts a convincing attack on the broad view, arguing (...) that it opens the "doors of memory" too far, but this commentary contends that the narrow view does not open them far enough. It may be preferable to adopt an intermediate view of the scope of memory, on which causal connection is sufficient for memory only when it involves encoding, storage, and retrieval of content. More demanding than the simple causal condition but less demanding than the autonoesis condition, the encoding-storage-retrieval condition implies that both episodic and semantic memory count as genuine forms of memory but that procedural memory does not.

__: In this essay I explore the account of imaginative phenomenology developed by Uriah Kriegel in _The Varieties of Consciousness_. On his view, the difference between perceptual phenomenology and imaginative phenomenology arises from the way that they present the existential status of their object: While perceptual experience presents its object as existent, imaginative experience presents its object as non-existent. While I agree with Kriegel that it’s likely that the difference between imaginative phenomenology and perceptual phenomenology is one not just of (...) degree but of kind, I worry about the particular account that he has developed. I thus develop two lines of criticism. First, I question whether Kriegel is right that imagination presents its object as non-existent. Second, I question whether this account of imaginative phenomenology is consistent with other commonly-accepted facts about the nature of imagination. _Keywords_: Imagination; Perception; Phenomenology; J.-P. Sartre; Epistemic Value; Emotion ___Fenomenologia dell’immaginazione e status esistenziale_ _Riassunto_: In questo articolo intendo indagare l’approccio alla descrizione della fenomenologia dell’immaginazione sviluppata da Uriah Kriegel in _The Varieties of Consciousness_. Dal suo punto di vista, la differenza tra fenomenologia della percezione e fenomenologia dell’immaginazione si mostra nel modo in cui queste presentano lo status esistenziale dei loro oggetti: se l’esperienza percettiva presenta il proprio oggetto come esistente, l’esperienza immaginativa lo presenta come non-esistente. Per un verso, concordo con Kriegel sulla probabilità che la differenza tra fenomenologia dell’immaginazione e fenomenologia della percezione non sia di grado ma di genere, mentre, per altro verso, non sono convinta della correttezza del suo approccio. Pertanto vorrei sollevare due criticità. In primo luogo, mi chiedo se Kriegel sia nel giusto quando ritiene che l’immaginazione presenti il proprio oggetto come non-esistente; in secondo luogo, mi chiedo se questa descrizione della fenomenologia dell’immaginazione sia coerente con altri fatti, comunemente accettati, circa la natura dell’immaginazione. _Parole chiave_: Immaginazione; Percezione; Fenomenologia; J.-P. Sartre; Valore epistemico; Emozione. (shrink)

My purpose in this dissertation is to investigate the workings of the imagination. As I argue in Chapter One, such an investigation reveals that we cannot adequately account for the phenomenon of imagining without invoking mental imagery. I thus develop and defend an imagery-based account of the imagination, which I call the imagery model. ;Despite its intuitive appeal and a long philosophical history, the imagery model has nonetheless fallen into disfavor in contemporary discussions of the imagination. This is due, at (...) least in part, to a strong presumption against mental images that has developed in this century. Overcoming this presumption is the primary task of Chapter Two. In Chapter Three, I address a second motivation for the rejection of the imagery model, namely, that there seem to be some mental exercises which are clearly exercises of the imagination but yet which do not consist of imagery. By separating the imagery model from several controversial theses with which it has been associated, I show how the imagery model can protect itself from the threat of these counterexamples. ;Once these obstacles to the acceptance of the imagery model have been removed, the need remains to provide an explanation of the role that the image plays in imagining. As I suggest, although the image is not what is imagined, it is in virtue of the image that anything is imagined at all. More specifically, the image serves to capture the subject of the imagining. My discussion of this claim in Chapter Four is heavily influenced by recent work in the philosophy of language; in particular, I rely on many of the insights of the causal theory of reference developed by Saul Kripke and Keith Donnellan. ;Ultimately, having developed a picture of the workings of the imagination, I take up what I call the question of imaginability, namely, "What can we imagine?" The imagery model yields the obvious result that the imaginable is limited to the imageable. I explore the consequences of this result and, in particular, the consequences it has for the use of the imagination as an epistemological guide to modality. (shrink)

The Kripkean conception of natural kinds (kinds are defined by essences that are intrinsic to their members and that lie at the microphysical level) indirectly finds support in a certain conception of a law of nature, according to which generalizations must have unlimited scope and be exceptionless to count as laws of nature. On my view, the kinds that constitute the subject matter of special sciences such as biology may very well turn out to be (...) class='Hi'>natural despite the fact that their essences fail to be microphysical or micro-based. On the causal conception of natural kinds I privilege, the naturalness of a kind is a function of the fact that it figures prominently in at least one causal law. However, there is a strong tendency prevailing among contemporary philosophers to assume that, in order to count as proper laws generalizations must be expectionless. Since most generalizations tracked down by the special sciences turn out not to fulfill these criteria, what this conception of a law implies is that most of the generalizations the special sciences trade in are not proper laws. It follows that, on this view, most if not all of the kinds the special sciences dealing with turn out not to constitute natural kinds, understood as kinds to which bona fide laws apply. In order to establish that the non-microstructurally defined kinds that fall within the domain of enquiry of the special sciences are eligible for the status of natural kind, I must therefore establish that generalizations needn’t have unlimited scope and be exceptionless to count as laws of nature. This is precisely what I seek to do in this paper. I begin by arguing that the question “what is a law of nature?” is most naturally interpreted as the question “what features must generalizations exhibit in order to ground scientific explanations?” and by offering reasons to believe that generalizations needn’t be exceptionless and have unlimited scope to play the crucial role laws have been thought to play in scientific explanation. Drawing on Sandra Mitchell [Mitchell, S. (2000). Philosophy of Science, 67, 242–265] and James Woodward’s [Woodward, J. (1997). Philosophy of science, 64 (proceedings), 524–541; Woodward, J. (2000). British Journal for the philosophy of science, 51(2), 197–254; Woodward, J. (2001). Philosophy of science, 68, 1–20] work, I subsequently develop an alternative account of the criteria generalizations must satisfy in order to count as laws of nature, which at least some of the generalizations of the special sciences turn out to fulfill. I thus give credence to the idea that at least some of the kinds that fall within the domain of the special sciences figure in laws of nature, and I thereby restore the possibility that some special science kinds deserve to be deemed natural.

As physicalisms of various kinds have faced difficulties in recent years, the time has come to explore possible alternatives, one of which is yinyang ontology. A yinyang theorist is expected to provide a plausible account of causation to replace the traditional notion of causation. The present paper is critical of the Humean tradition, which understands the relata of causal relations in terms of passive materiality so that humans use referential terms to describe causal relations constructively. But an alternative notion (...) of reference is available according to which causal relata are active processors of the information with which they interact. On this latter view, humans use referential language to describe the structure in which the relata interrelate themselves so that the structure can be understood hermeneutically. Reference on this view is naturalized. In this article I advance two arguments for this thesis, one concerning the informationality of states and the other related to the essentiality of properties.

Classifications are useful and efficient. We group things into kinds to facilitate the acquisition and transmission of important, often tacit, information about a particular entity qua member of some kind. Whilst it is universally acknowledged that classifications are useful, some scientific classifications (e.g. chemical elements) are held to higher epistemic standards than folk classifications (e.g. bugs). Scientific classifications in terms of ‘natural kinds’ are considered to be more reliable and successful because they are highly projectible and support (...) law-like and inductive generalisations. What counts as a natural kind is, however, controversial: according to essentialists (e.g. Putnam, Kripke, Ellis) natural kinds are mind-independent and possess essential characteristics; according to promiscuous realists (e.g. Dupre ) there are ‘countless legitimate, objectively grounded ways of classifying objects in the world’; and according to scientific realists (e.g. Boyd, Psillos) natural kinds are grounded in the ‘causal structure of the world’. More specifically, realism about kinds can be understood as a commitment to the existence of natural divisions (kinds) in the world that we come to know as a result of mature scientific investigation into the nature of such kinds. Realism about natural kinds is supported and articulated in terms of three main arguments, metaphysical, semantical, and epistemological. In the first part of my thesis I offer a sustained and systematic investigation of these three main arguments, with their respective promises and prospects for the viability of realism about kinds and I find them wanting, whilst in the second part of the thesis I pursue an unexplored line of inquiry regarding natural kinds and propose a mild realism about natural kinds via the ontology of real patterns.

The notion of 'natural kinds' has been central to contemporary discussions of metaphysics and philosophy of science. Although explicitly articulated by nineteenth-century philosophers like Mill, Whewell and Venn, it has a much older history dating back to Plato and Aristotle. In recent years, essentialism has been the dominant account of natural kinds among philosophers, but the essentialist view has encountered resistance, especially among naturalist metaphysicians and philosophers of science. Informed by detailed examination of classification in the (...) natural and social sciences, this book argues against essentialism and for a naturalist account of natural kinds. By looking at case studies drawn from diverse scientific disciplines, from fluid mechanics to virology and polymer science to psychiatry, the author argues that natural kinds are nodes in causal networks. On the basis of this account, he maintains that there can be natural kinds in the social sciences as well as the natural sciences. (shrink)

This article argues for a different outlook on the concept of extension, especially for the reference of general terms in scientific practice. Scientific realist interpretations of the two predominant theories of meaning, namely Descriptivism and Causal Theory, contend that a stable cluster of descriptions or an initial baptism fixes the extension of a general term such as a natural kind term. This view in which the meaning of general terms is presented as monosemantic and the referents as stable, homogeneous, (...) and unchangeable, however, does not reflect the various practices involved in the investigation of research materials and the related application of general terms in scientific practice. By drawing on the taxonomic diversity, particularly of structure-based classifications in chemical databases, this article illustrates the limited utility of such a concept of extension. Research materials often exhibit a plurality of material dimensions that, within different research contexts, allow for various and often equally significant taxonomic demarcations. In light of this, the extension of a general term cannot be uniquely determined by a supposedly independent nature of the referent but is relative to the model context under which the materials are investigated. This significance and plurality of the model context, I claim, needs to be mirrored in an account of meaning that is supposed to reflect scientific reality. On this account, the aim of this article is to present an alternative perspective on the concept of extension to accommodate the diverse material practices that determine the application of general terms in science.

Through a detailed explication of Bernard Bolzano's semantics of natural kind terms, I elucidate why and to what extent he should be recognized as a remarkable anticipator of semantic externalism. Bolzano deals with kind terms in a brief sub-section of the first volume of his Theory of Science. He divides such terms into two sub-categories, roughly corresponding to organic and inorganic kinds. It is Bolzano's account of inorganic kind terms, such as ‘gold’, that confers on him the status (...) of an anticipator of semantic externalism. He argues that ‘gold’ may be used in a way such that the superficial attributes that language users associate with it merely serve to enable them to recognize its instances. They do not, however, constitute the idea designated by the term nor do they determine its extension. Instead, the term designates an idea representing gold's unknown inner attributes, which are causally responsible for its superficial attributes. (shrink)
