We give an account of some relationships between the principles of Constant and Atom Exchangeability and various generalizations of the Principle of Instantial Relevance within the framework of Inductive Logic. In particular we demonstrate some surprising and somewhat counterintuitive dependencies of these relationships on ostensibly unimportant parameters, such as the number of predicates in the overlying language.

In this paper we consider a natural generalization of the Principle of Instantial Relevance and give a complete characterization of the probabilistic belief functions satisfying this principle as a family of discrete probability functions parameterized by a single real δ ∊ [0, 1).

Journal of Experimental and Theoretical Artificial Intelligence What is the difference between a simulation of X and simply another instance of X? Is there a point at which the ‘‘virtual reality’’ of a model becomes the real thing? This paper examines these questions using cases taken from recent developments in evolutionary engineering and artificial life research. By implementing the Darwinian mechanism and setting it to work on a design problem, scientists and engineers find that evolution not only can improve prior (...) designs, but also produce novel technological solutions. Artificial life systems Tierra and Avida which operate at a higher level of abstraction than evolutionary engineering applications. I analyze simulation as a rational concept ‘‘S simulates R’’ and argue that it always includes some relevant property P, of R, that is captured but that there is always also some other that it omits, and that pragmatic factors fix what counts as relevant. The border between a simulation and an instance can change depending upon the context. I show that in one sense, evo-technology and artificial life simulate organic evolution, but in another relevant sense they are instances of evolution itself. Biologists can use such systems to experimentally test evolutionary hypotheses such as those involving the evolution of complex features and altruism. This analysis suggests lines for future research on broader questions about models classification and confirmation. (shrink)

The quantified relevant logic RQ is given a new semantics in which a formula for all xA is true when there is some true proposition that implies all x-instantiations of A. Formulae are modelled as functions from variable-assignments to propositions, where a proposition is a set of worlds in a relevant model structure. A completeness proof is given for a basic quantificational system QR from which RQ is obtained by adding the axiom EC of 'extensional confinement': for all x(A V (...) B) -> (A V for all xB). with x not free in A. Validity of EC requires an additional model condition involving the boolean difference of propositions. A QR-model falsifying EC is constructed by forming the disjoint union of two natural arithmetical structures in which negation is interpreted by the minus operation. (shrink)

The Routley-Meyer relational semantics for relevant logics is extended to give a sound and complete model theory for many propositionally quantified relevant logics (and some non-relevant ones). This involves a restriction on which sets of worlds are admissible as propositions, and an interpretation of propositional quantification that makes ∀ pA true when there is some true admissible proposition that entails all p -instantiations of A . It is also shown that without the admissibility qualification many of the systems considered are (...) semantically incomplete, including all those that are sub-logics of the quantified version of Anderson and Belnap’s system E of entailment, extended by the mingle axiom and the Ackermann constant t . The incompleteness proof involves an algebraic semantics based on atomless complete Boolean algebras. (shrink)

It is widely accepted that there is a distinction to be made between the explicit content and the implicit import of an utterance. There is much less agreement about the precise nature of this distinction, how it is to be drawn, and whether any such two-way distinction can do justice to the levels and kinds of meaning involved in utterance interpretation. Grice’s distinction between what is said by an utterance and what is implicated is probably the best known instantiation of (...) the explicit/implicit distinction. His distinction, along with many of its post-Gricean heirs, is closely entwined with another distinction: that between semantics and pragmatics. Indeed, on some construals they are seen as essentially one and the same; “what is said” is equated with the truthconditional content of the utterance which in turn is equated with (context-relative) sentence meaning, leaving implicatures (conventional and conversational) as the sole domain of pragmatics.

It is often said that the ontological argument fails because it wrongly treats existence as a first-level property or predicate. This has proved a controversial claim, and efforts to evaluate it are complicated by the fact that the words ‘existence is not a property/predicate’ have been used by philosophers to make at least three different negative claims: (a) one about a first-level phenomenon possessed by objects like horses, stones, you and me; (b) another about the logical form of assertions of (...) existence; and (c) still another about a second-level phenomenon possessed by concepts when they are instantiated. I argue that only the last of these claims, originally voiced by Kant, is both plausible and relevant to the ontological argument. And I try to show that the relevance of the Kantian version comes from its providing the underlying justification for a different, and far less controversial, criticism of the ontological argument.

We give a unified account of some results in the development of Polyadic Inductive Logic in the last decade with particular reference to the Principle of Spectrum Exchangeability, its consequences for Instantial Relevance, Language Invariance and Johnson's Sufficientness Principle, and the corresponding de Finetti style representation theorems.

Our understanding of body ownership largely relies on the Rubber Hand Illusion (RHI) paradigm where synchronous stroking of the real and fake hands leads to an illusion of ownership of RH provided its physical, anatomical, and spatial plausibility. Self-attribution of a fake hand also occurs during visuomotor synchrony, when the visual feedback of self-initiated movements follows the trajectory of the instantiated motor command. In both cases, the experience of ownership is established through bottom-up integration and top-down prediction of multisensory (proximodistal) (...) cues within the peripersonal space. It seems, however, that depending on whether the signals are externally or self-generated, top-down expectation signals are qualitatively different. On the one hand, in RHI, the sensory correlations are modulated by empirically induced priors about the internal model of the body. On the other hand, in mRHI, body ownership is actively shaped by processes allowing for continuous comparison between the actual and predicted sensory consequences of the actions. Ample research demonstrates that the differential processing of the predicted and the actual reafferent information is addressed by the central nervous system via an internal Forward Model (FM). Indeed, results from mRHI suggest that in action-contexts mechanism underlying body ownership could be similar to the FM. Crucially FMs integrate across all sensory input including not only proximodistal (visuomotor) but also purely distal sensory signals (visuoauditory). Thus if body ownership results from a consistency of FM, it would be affected by the (in)congruency of purely distal signals provided that they inform about the action-consequences relevant to the task. Here we explicitly address this question. To test our hypothesis, we devise an embodied VR-based task where action outcomes were signaled by distinct auditory cues. By manipulating the cues with respect to their spatial, temporal and semantic congruency, we show that purely distal feedback violating predictions about action outcomes compromises both body ownership and performance. These results demonstrate that body ownership is influenced by cues which not only pertain to the body itself but also those arising outside of the body, and suggest that in goal-oriented tasks body ownership might result from the consistency of forward models.

Technical hitches mar van Gelder's proposed map of the conceptual landscape, particularly with respect to descriptive levels and the trio of instantiation, realisation, and implementation. However, for all the formal quibbles, van Gelder is onto something important; the tension he notes between computationalism and a dynamical alternative threatens to transform the way we conduct cognitive science research.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS The Recovery of Virtue: The Relevance of Aquinas for Christian Ethics. By JEAN PORTER. Louisville, Ky.: Westminster/John Knox Press, 1990. Pp. 208. $24.95 (cloth). On Faith: Summa Theologiae 2-2, qq. 1-16 of St. Thomas Aquinas. Translated by MARK D. JoRDAN. Readings in the Summa the· ologiae, Vol. 1. Notre Dame, Ind.: University of Notre Dame Press, 1990. Pp. 208. $9.95 (paper). Two recent publications well serve (...) the growing interest in what Aquinas has to say about virtue, human and divine. First, Jean Porter carefully studies the general " moral theory of Thomas Aquinas's Summa theologiae in the light of the problematics of contemporary Christian ethics, Protestant as well as Catholic " (p. 13). Her work incorporates a readable introduction to the main components of Aquinas's moral philosophy: a realist conception of the good, the instantiation of that good in the world of human actions and goals, and the ordering of choice towards the good through virtue. Secondly, Mark Jordan introduces a new translation in a " spare but accessible English" (p. 18) of the treatise on faith (Summa theologiae Ha-Hae qq, 1-16). Since both volumes concern the secunda pars of Aquinas's Summa theologiae, we can suitably examine their merits in this single review. The Recovery of Virtue aims at drawing the thought of Aquinas into a clearer dialogue with those who write about theological ethics in the English-speaking world. Accordingly, Porter prefaces her fine study with a fair, though brief, survey of Catholic moral theology since Vatican II and summary accounts of the dominant themes in the works of Gene Outka, James Gustafson, and Stanley Hauerwas. She th.en turns to a " reconstruction of the more strictly philosophical components " of Aquinas's moral theory as contained in the Summa theologiae. In chapter 2, Porter explains some basic notions which undergird Aquinas's general theory of morals, for example, his notion of goodness as something real; the premise that what is good or best for anyone is so in virtue of its being of a certain kind; the assertion that the self remains a legitimate " object " of theological charity; the view that one discovers intelligibility and organization within the created order; and finally, the conviction that the final perfection of the ra141 142 BOOK REVIEWS tional creature transcends the limits which creatureliness itself imposes. In chapter 3, Porter gives a fine account of Aquinas's action theory, illustrated by the sorts of good examples that Aquinas himself would have used today. Thomas Gilby once remarked that end so dominates the secunda pars that it should he read through to say what it means. Porter's first three chapters render a clear, organized analysis of Aquinas's moral teleology. Still, I would like to raise two small issues which may suggest lines for further inquiry. First, Porter asks whether Aquinas's teleological frame of reference allows for performing actions " without reference to any wider aim" (p. 76). As examples of those things which one can simply desire for themselves, she proposes engagement in or with: " fine music, a life of service, chocolates, children, religious ecstasy, sexual ecstasy... the list is endless" (loc. cit.). First of all, this list of examples seems to ignore a basic distinction between a finis cui and a finis cuius gratia, or the difference between something that is sought for itself and something which is sought for the sake of a further end. A person may never virtuously subordinate children and (service to) other people to his or her own goals or purposes (including delight). We can render them their due according to the diverse types of justice, even expect to receive something good from them in theological hope, and above all love them in theological charity. But we can never turn them into a finis cnius gratia. On the other hand, fine music, chocolates, and ecstasy both sexual and religious (if by the latter one means created thoughts and feelings about God and not union with God himself) always remain instrumental, that is, they can never virtuously serve as a finis cui. If we take Porter's example, Aquinas's teleological framework includes the chocolate ice-cream... (shrink)

We give a brief account of some de Finetti style representation theorems for probability functions satisfying Spectrum Exchangeability in Polyadic Inductive Logic, together with applications to Non-splitting, Language Invariance, extensions with Equality and Instantial Relevance.

This paper is a sequel to the joint publication of Scott and Krauss in which the first aspects of a mathematical theory are developed which might be called "First Order Probability Logic". No attempt will be made to present this additional material in a self-contained form. We will use the same notation and terminology as introduced and explained in Scott and Krauss, and we will frequently refer to the theorems stated and proved in the preceding paper. The main objective of (...) this study is to show that the probability of symmetric probability systems may be represented as a "weighted average" of what might be called "product probabilities". We then discuss some applications of our results to Carnap's "Principle of instantial relevance", which plays an important role in his system of inductive logic. (shrink)

This paper presents a new account of Hume’s “probability of causes”. There are two main results attained in this investigation. The first, and perhaps the most significant, is that Hume developed – albeit informally – an essentially sound system of probabilistic inductive logic that turns out to be a powerful forerunner of Carnap’s systems. The Humean set of principles include, along with rules that turn out to be new for us, well known Carnapian principles, such as the axioms of semiregularity, (...) symmetry with respect to individuals (exchangeability), predictive irrelevance and positive instantial relevance. The second result is that Hume developed an original conception of probability, which is subjective in character, although it differs from contemporary personalistic views because it includes constraints that are additional to simple consistency and do not vary between different persons. The final section is a response to Gower’s thesis, by which Hume’s probability of causes is essentially non-Bayesian in character. It is argued that, on closer examination, Gower’s reading of the relevant passages is untenable and that, on the contrary, they are in accordance with the Bayesian reconstruction presented in this paper.

This paper examines from a cognitive perspective the rhetorical and epistemic advantages that can be gained from the use of (extended) metaphors in political discourse. We defend the assumption that extended metaphors can be argumentatively exploited, and provide two arguments in support of the claim. First, considering that each instantiation of the metaphorical mapping in the text may function as a confirmation of the overall relevance of the main core mapping, we argue that extended metaphors carry self-validating claims that (...) increase the chances of their content being accepted. Second, we show how the recognition of an extended metaphor’s sophistication and relevance (on behalf of the addressee) can benefit the speaker’s perceived competence (ethos). We then assess whether these two arguments measure against the dual epistemic monitoring postulated in the notion of epistemic vigilance (i.e., assessment of the source of a message and assessment of the message) and conclude that extended metaphors may fulfil the requirements of epistemic vigilance and lead to the stabilisation of a belief. We illustrate our account with an analysis of the extended metaphor of the USA as an empire found in a political pamphlet written by the Swiss politician Oskar Freysinger. (shrink)

Most instantiations of the inference ‘y; so if x, y’ seem intuitively odd, a phenomenon known as one of the paradoxes of the material conditional. A common explanation of the oddity, endorsed by Mental Model theory, is based on the intuition that the conclusion of the inference throws away semantic information. We build on this explanation to identify two joint conditions under which the inference becomes acceptable: (a) the truth of x has bearings on the relevance of asserting y; (...) and (b) the speaker can reasonably be expected not to be in a position to assume that x is false. We show that this dual pragmatic criterion makes accurate predictions, and contrast it with the criterion defined by the mental model theory of conditionals, which we show to be inadequate. (shrink)

A chemical substance is instantiated in the material world by a number of quantities of such substance, placed in different locations. A change of location implies a change in the net of relationships entertained by the QCS with the region wherein it is found. This fact entails changes of the ontological status of the CS, as this is not fully determined by the inherent features of the CS and includes a relevant relational contribution. In order to demonstrate this thesis, we (...) have chosen to analyse the status of quantities of a same CS that are synchronically located in different spacetime regions: a synthetic lab, a lab where the QCS is turned into a material, an industrial plant, the market where the QCS gets a price and a dump waste where the QCS is discarded, respectively: Chemical substance Open image in new window material Open image in new window product Open image in new window goods Open image in new window wasteThe use of first-order predicate logic, mereology and locative logic allows carrying out a regimentation process that highlights the ontological commitments implied by the formal expressions through which each element of the aforementioned series can be described. The presence of relational properties discloses the systemic nature of the CS instantiated within a spacetime region. The implications of such an aspect are discussed. (shrink)

The first half of this paper replies to three postmodernist challenges to belief in objective intrinsic value. One lies in the claim that the language of objective value presupposes a flawed, dualistic distinction between subjects and objects. The second lies in the claim that there are no objective values which do not arise within and/or depend upon particular cultures or valuational frameworks. The third comprises the suggestion that belief in objective values embodies the representational theory of perception. In the second (...) half, a defence is offered of belief in objective intrinsic value. Objectivists hold that axiological properties supply interpersonal reasons for action for any relevant moral agent. The intrinsically valuable is understood as what there is reason to desire, cherish or foster in virtue of the nature of the state or object concerned. The concept of intrinsic value is shown to be instantiated, and defended against a range of criticisms. (shrink)

No one in philosophy has paid much attention to the virtue of honesty in recent years. Here is a trait for which it is easy to find consensus that it is a virtue, and furthermore, a very important virtue. It also has obvious relevance to what we see going on in contemporary politics, for instance, or in sports, the entertainment world, and education. Yet as far as I can tell, only one article in a philosophy journal has appeared in (...) several decades which discusses this virtue at any length. -/- In this chapter I have two central aims: (i) to sketch some of the conceptual parameters of the virtue of honesty in general, as well as its subordinate virtues, and then (ii) to draw on leading work in psychology to determine, at least in a preliminary way, whether we should think that most people instantiate this virtue or not.

I use Ralph Ellison's Invisible Man to consider the requirements of existentialism to be relevant to racialized experience. Black existentialism is distinguished from white existentialism by its focus on anti-black racism. However, black existentialism is similar to white existentialism in its moral requirement that agents take responsibility so as to be in good faith. Ralph Ellison's invisible man displays good faith at the end of the novel by assuming responsibility for his particular situation. The idiosyncratic development of the novel can (...) be interpreted as an example of the ways in which existentialist values ought to be instantiated through unique individual experience. However, blackness, or any racial identity, is not itself an existential structure because it is not universal. Rather, existentialist requirements for good faith can be applied to racialized situations by both whites and blacks. (shrink)

We discuss the implementation of Responsible Research and Innovation (RRI) within a project for the development of an AI-supported exergame for assisted movement training, outline outcomes and reflect on methodological opportunities and limitations. We adopted the responsibility-by-design (RbD) standard (CEN CWA 17796:2021) supplemented by methods for collaborative, ethical reflection to foster and support a shift towards a culture of trustworthiness inherent to the entire development process. An embedded ethicist organised the procedure to instantiate a collaborative learning effort and implement RRI (...) in a translational context. Within the interdisciplinary setting of the collaboration and with the support of a technoethicist, we successfully identified relevant, project-specific challenges and developed a roadmap with derived actions, thus meaningfully integrating RRI into the development process. We discuss the methodological procedure in terms of its effectiveness and efficiency, the allocation of responsibilities and roles, particularly regarding potential frictions in the interdisciplinary context with embedded ethics, and the challenges of the translational context. We conclude that the responsibility-by-design standard effectively established a productive workflow for collaborative investigation and work on ethical challenges. We reflect on methodological difficulties and propose possible avenues to our approach. (shrink)

Theorists of first person thought seem to be faced with a pervasive dilemma: either accept the view that varying reference and sense are bound up together in first person thought, but then reject person-to-person shareability; or else, maintain the shareability of first person thought or belief at the price of giving up the connection between sense and subject-to-subject changing reference. Here, the author will argue that this is, in fact, a spurious dilemma based largely upon a failure to appreciate, if (...) not the existence, at least the crucial importance of the distinction between types, instantiable types and instantiated types of thought or belief. Only the level of the instantiable type is relevant for a proper assessment of the question of whether two different subjects have the same first person thought. (shrink)

Theories of quantum gravity generically presuppose or predict that the reality underlying relativistic spacetimes they are describing is significantly non-spatiotemporal. On pain of empirical incoherence, approaches to quantum gravity must establish how relativistic spacetime emerges from their non-spatiotemporal structures. We argue that in order to secure this emergence, it is sufficient to establish that only those features of relativistic spacetimes functionally relevant in producing empirical evidence must be recovered. In order to complete this task, an account must be given of (...) how the more fundamental structures instantiate these functional roles. We illustrate the general idea in the context of causal set theory and loop quantum gravity, two prominent approaches to quantum gravity. (shrink)

Empathy is thought to play a key role in motivating prosocial behavior, guiding our preferences and behavioral responses, and providing the affective and motivational base for moral development. While these abilities have traditionally been examined using behavioral methods, recent work in evolutionary biology, developmental and cognitive neuroscience has begun to shed light on the neural circuitry that instantiate them. The purpose of this article is to critically examine the current knowledge in the field of affective neuroscience and provide an integrative (...) and comprehensive view of the computational mechanisms that underlie empathy. This framework is of general interest and relevance for theory as well as for assisting future research in the domains of affective developmental neuroscience and psychopathology. (shrink)

Berkeley’s likeness principle states that only an idea can be like an idea. In this paper, I argue that the principle should be read as a premise only in a metaphysical argument showing that matter cannot instantiate anything like the sensory properties we perceive. It goes against those interpretations that take it to serve also, if not primarily, an epistemological purpose, featuring in Berkeley’s alleged Representation Argument to the effect that we cannot reach beyond the veil of our ideas. First, (...) in section 1, I raise some concerns about the traditional narrative concerning the likeness principle’s role in Berkeley’s argumentation. In section 2, I delineate an alternative narrative, arguing that there is no ‘missing premise’ in his alleged Representation Argument we need to explain simply because he advances no argument like that in the first place. In section 3–4, I provide a close reading of the relevant passages—first from the _Principles_, then the _Dialogues_—and their contexts, supporting textually a purely metaphysical interpretation of the likeness principle arguments. In section 5, I address some possible objections, based on the phrasing of the likeness principle passages and some related texts. (shrink)

It is plausible to think that our knowledge of linguistic types can bejustified by what we know about the tokens of these types. But one then hasto explain what it is about the relation a type bears to its tokens that makespossible the move from knowledge of the concrete to knowledge of theabstract. I argue that the standard solution to this difficulty, that the relevant relation is instantiation and that the transition is inductive generalization, is inadequate. I propose an alternative, (...) according to which tokens are representations of the type they belong to. I also defend this view against the charge that it cannot account for the systematic ambiguity of expressions like ‘word’ or ‘sentence’, and the objection that it leads to an implausible form of Platonism.

Even though the talk of causal bases is commonplace in traditional and contemporary discussions about dispositions, the concept of causal bases has never been systematically investigated. This paper aims to fill this gap by developing the causal-grounding account. This account takes two roles as definitory for causal bases. First, causal bases are possible causes of disposition manifestations. Second, causal bases are metaphysical grounds of disposition instantiations. In this paper, we show that the causal-grounding account (CGA) achieves crucial distinctions (for example (...) between causal bases and manifestation conditions), captures relevant traditional features of causal bases, and can be invoked to support the causal efficacy of disposition instantiations. At the same time, CGA does not require that causal bases have to be categorical or intrinsic. This, in turn, allows us to remain neutral concerning fundamental properties, the existence of dispositional or extrinsic causal bases, multi-track dispositions, and the reducibility of dispositions. This neutrality grants the suitability of our account for different philosophical projects and discussions. (shrink)

This is a reply to Timothy Williamson ’s paper ‘Tennant’s Troubles’. It defends against Williamson ’s objections the anti-realist’s knowability principle based on the author’s ‘local’ restriction strategy involving Cartesian propositions, set out in The Taming of the True. Williamson ’s purported Fitchian reductio, involving the unknown number of books on his table, is analyzed in detail and shown to be fallacious. Williamson ’s attempt to cause problems for the anti-realist by means of a supposed rigid designator generates a contradiction (...) with arithmetic right away, upon instantiating the obviously relevant theorem that every natural number is provably odd or provably even. The paper also explains and formulates a globally restricted knowability principle, which likewise blocks the attempted reductio. (shrink)

The gamer’s dilemma :31–36, 2009) asks whether any ethical features distinguish virtual pedophilia, which is generally considered impermissible, from virtual murder, which is generally considered permissible. If not, this equivalence seems to force one of two conclusions: either both virtual pedophilia and virtual murder are permissible, or both virtual pedophilia and virtual murder are impermissible. In this article, I attempt, first, to explain the psychological basis of the dilemma. I argue that the two different action types picked out by “virtual (...) pedophilia” and “virtual murder” set very different expectations for their token instantiations that systematically bias judgments of permissibility. In particular, the proscription of virtual pedophilia rests on intuitions about immoral desire, sexual violations, and a schematization of a powerful adult offending against an innocent child. I go on to argue that these differences between virtual pedophilia and virtual murder may be ethically relevant. Precisely because virtual pedophilia is normally aversive in a way that virtual murder is not, we plausibly expect virtual pedophilia to invite abnormal and immorally desirous forms of engagement.

Degree‐sentences, i.e. sentences that seem to refer to things that allow of degrees, are widely used both inside and outside of philosophy, even though the metaphysics of degrees is much of an untrodden field. This paper aims to fill this lacuna by addressing the following four questions: [A] Is there some one thing, such that it is degree sensitive? [B] Are there things x, y, and z that stand in a certain relation to each other, viz. the relation that x (...) has more y than z? [C] In those cases in which degree sentences do not refer to phenomena that are degree sensitive, what is responsible for their prima facie seeming to do so? [D] If there are degree sensitive things, to which ontological categories do they belong? We answer each of these questions by arguing that there are, metaphysically speaking, different phenomena that degree sentences refer to: some refer to determinates that emanate from a certain determinable, others to tokens that are instantiations of a certain type, and yet others to what we call ‘complex, resultant properties that are constituted by stereotypical properties’. Finally, we show the relevance of our answers by applying them to the notions of freedom and belief. (shrink)

In his recent article, Ben-Moshe offers an account of conscientious objection in terms of the truth of the underlying moral objections, as judged by the standards of an impartial spectator. He seems to advocate for the view that having a valid moral objection to X is the sole criteria for the instantiation of a right to conscientiously object to X, and seems indifferent to the moral status of the prevailing moral attitudes. I argue that the moral status of the prevailing (...) moral attitudes is relevant, and that a good faith disagreement between those who condone the relevant act and those who object to it is a criterion for CO. In this light, I suggest that CO is a sociopolitical device for managing differing ethical perspectives, particularly in the context of collective moral change. Thus, it is misguided to equate having a valid moral objection with the recognition of a CO. (shrink)

Derek Parfit, Joseph Raz, and T. M. S canlon, among others, all hold that reasons for action are provided by facts about those actions. They also hold that the fact that an action would promote or achieve the object of an agent's desire is not one of the relevant facts, and does not provide a reason. Rather, the facts that provide reasons are typically facts about valuable states of affairs that the action is likely to bring about, or valuable properties (...) that the action itself will instantiate. For this reason it is appropriate to call Parfit, Raz, and Scanlon "value-based" theorists about reasons for action. In contrast to value-based theorists, there is a strong current of contemporary theorizing, starting with Bernard Williams, that can be called "desire-based." Desire-based theorists argue that practical reasons should be understood in terms of the desires of the agents who are said to have those reasons. (shrink)

I apply James Woodward’s interventionist theory of causation to organic chemistry, modelling three different ways that chemists are able to manipulate the reaction conditions in order to control the outcome of a reaction. These consist in manipulations to the reaction kinetics, thermodynamics, and whether the kinetics or thermodynamics predominates. It is possible to construct interventionist causal models of all of these kinds of manipulation, and therefore to account for them using Woodward’s theory. However, I show that there is an alternate, (...) more illuminating way of thinking about the third kind of reaction control, according to which chemists are thought of as manipulating which causal system is instantiated. I show that our ability to manipulate which system is instantiated is an important part of our ability to control the world, as is therefore especially relevant to interventionism. Thus, considering examples from organic chemistry leads to the identification of an important extension to Woodward’s theory. Finally, this investigation into reaction control in organic chemistry also has a more general implication: it suggests that interventionism results in a version of pragmatism about causation.

This article argues that rapid eye movement (REM) dreaming is elaborative encoding for episodic memories. Elaborative encoding in REM can, at least partially, be understood through ancient art of memory (AAOM) principles: visualization, bizarre association, organization, narration, embodiment, and location. These principles render recent memories more distinctive through novel and meaningful association with emotionally salient, remote memories. The AAOM optimizes memory performance, suggesting that its principles may predict aspects of how episodic memory is configured in the brain. Integration and segregation (...) are fundamental organizing principles in the cerebral cortex. Episodic memory networks interconnect profusely within the cortex, creating omnidirectional “landmark” junctions. Memories may be integrated at junctions but segregated along connecting network paths that meet at junctions. Episodic junctions may be instantiated during non–rapid eye movement (NREM) sleep after hippocampal associational function during REM dreams. Hippocampal association involves relating, binding, and integrating episodic memories into a mnemonic compositional whole. This often bizarre, composite image has not been present to the senses; it is not “real” because it hyperassociates several memories. During REM sleep, on the phenomenological level, this composite image is experienced as a dream scene. A dream scene may be instantiated as omnidirectional neocortical junction and retained by the hippocampus as an index. On episodic memory retrieval, an external stimulus (or an internal representation) is matched by the hippocampus against its indices. One or more indices then reference the relevant neocortical junctions from which episodic memories can be retrieved. Episodic junctions reach a processing (rather than conscious) level during normal wake to enable retrieval. If this hypothesis is correct, the stuff of dreams is the stuff of memory. (shrink)

Recent experiments have shown that when individuals with a substance use disorder are confronted with drug-related cues, they exhibit an automatically activated tendency to approach these cues. The strength of the drug approach bias has been associated with clinically relevant measures, such as increased drug craving and relapse, and activations in brain reward areas. Retraining the approach bias by means of cognitive bias modification has been demonstrated to decrease relapse rates in patients with an alcohol use disorder and to reduce (...) alcohol cue-evoked limbic activity. Here, we review empirical and theoretical literature on the drug approach bias and explore two distinct models of how the drug approach bias may be embodied. First, we consider the “biological meaning” hypothesis, which grounds the automatic approach bias in the natural meaning of the body. Second, we consider the “sensorimotor hypothesis,” which appeals to the specific sensorimotor loops involved in the instantiation of addictive behaviors as the basis of the automatic approach bias. In order to differentiate between the adequacies of these competing explanations, we present specific, predictions that each model should make. (shrink)

The systems T N and T M show that necessity can be consistently construed as a predicate of syntactical objects, if the expressive/deductive power of the system is deliberately engineered to reflect the power of the original object language operator. The system T N relies on salient limitations on the expressive power of the language L N through the construction of a quotational hierarchy, while the system T Mrelies on limiting the scope of the modal axioms schemas to the sublanguage (...) L infM +, which corresponds exactly with the restrictive hierarchy of L N. The fact that L infM + is identical to the image of the metalinguistic mapping C + from the normal operator system into L M reveals that iterated operator modality is implicitly hierarchical, and that inconsistency is produced by applying the principles of the modal logic to formulas which have no natural analogues in the operator development. Thus the contradiction discovered by Montague can be diagnosed as the result of instantiating the axiom schemas with modally ungrounded formulas, and thereby adding radically new modal axioms to the predicate system.The predicate treatment of necessity differs significantly from that of the operator in that the cumulative models for the predicate system are strictly first-order. Possible worlds are not used as model-theoretic primitives, but rather alternate models are appealed to in order to specify the extension of N, which is semantically construed as a first-order predicate. In this manner, the intensional aspects of modality are built into the mode of specifying the particular set of objects which the denotation function assigns to N, rather than in the specification of the basic truth conditions for modal formulas. Intensional phenomena are thereby localised to the special requirements for determining the extension of a particular predicate, and this does not constitute a structural modification of the first-order models, but rather limits the relevant class of models to those which possess an appropriate denotation function.

Several authors, e.g. Patrick Suppes and I. J. Good, have recently argued that the paradox of confirmation can be resolved within the developing subjective Bayesian account of inductive reasoning. The aim of this paper is to show that the paradox can also be resolved by the rival orthodox account of hypothesis testing currently employed by most statisticians and scientists. The key to the orthodox statistical resolution is the rejection of a generalized version of Hempel's instantiation condition, namely, the condition that (...) a PQ is inductively relevant to the hypothesis $(x)(Px\supset Qx)$ even in the absence of all further information. Though their reasons differ, it turns out that Bayesian and orthodox statisticians agree that this condition lies at the heart of the paradox. (shrink)

This article discusses why it is the case that we refuse to accept strange evaluative claims as being true in fictions, even though we are happy to go along with other types of absurdities in such contexts. For instance, we would refuse to accept the following statement as true, even in the con-text of a fiction: -/- (i) In killing her baby, Giselda did the right thing; after all, it was a girl. -/- This article offers a sensibilist diagnosis of (...) this puzzle, inspired by an observation first made by David Hume. According to sensibilism, the way we feel about things settles their evaluative properties. Thus, when confronted with a fictional scenario where the configuration of non-evaluative facts and properties is relevantly similar to the actual world, we refuse to go along with evaluative properties being instantiated ac-cording to a different pattern. It is the attitudes we hold in the actual world that fix the extension of evaluative properties, even in non-actual worlds. When engaging with a fiction, we (to some extent) leave our be-liefs about what the world is like behind, while taking our emotional atti-tudes with us into the fiction. To substantiate this diagnosis, this paper outlines a sensibilist semantics for evaluative terms, based on recent discussion regarding predicates of personal taste, and explains how, together with standard assumptions about the nature of fictional discourse, it makes the relevant predictions with respect to engagement with fictions.

ArgumentMuch recent research has established the importance of visualization in modern science. This essay treats, instead, of the continued importance of the aural and oral: the professorial voice. The professor remains important for science since so many scientists still instantiate this persona and, as is here argued, a “voice” constitutes an essential feature of it. The form of the essay reflects its contents. From the Middle Ages until well into the modern era, the archetypal professorial genre was the disputation, an (...) oral event recast in written form. Apropos of the traditional disputation, this essay begins with a disquisition more or less to the point. It concerns Nietzsche’s first major publication, which violated norms for the proper professorial voice, thus accelerated the destruction of his academic career. The essay then presents six theses on the professorial voice. The theses treat relevant aspects of the professorial voice from the Sophists onward. It is argued, in Weberian terms, that the professorial voice or persona embodies elements of charismatic and traditional authority which coexist with and condition the rational authority or “objectivity” of science.

This is the first part of a larger project that aims to develop a cross-categorical semantic account of a broad range of _as if_ constructions in English. In this paper, we focus on descriptive uses of _as if_ with regular truth-conditional content. The core proposal is that _as if_-phrases contribute hypothetical (_if_-like) and comparative (_as_-like) properties of situations, which are instantiated by an event, state, or larger situation when it resembles in some relevant respect its counterparts in selected stereotypical worlds (...) described by the clause embedded under _as if_. We motivate and develop this situation-semantic analysis in detail for examples like _Pedro danced as if he was possessed by demons_ where the modifying _as if_-adjunct is used to inferentially convey the manner of a reported activity. We extend this analysis to _as if_-complements of perception verbs in reports like _The soup tastes as if it contains fish sauce_, offering an alternative to conceptually problematic approaches that assimilate such perceptual resemblance reports to propositional attitude ascriptions. We also examine the predicative function of _as if_ in examples like _The state of the house is as if a tornado passed through it_ where the _as if_-phrase denotes a hypothetical comparative property of the nominal subject.

Through a simple model of autogenic interpreting system featuring molecular constraint-work dynamics, Deacon critically tackles the issue of the nature of information in living systems and proposes that interpretation of a molecule as information about something else is more important than molecular replication. Two aspects of the target article are highlighted in this commentary. First, Deacon’s illustrations nicely resonate with and instantiate the wisdom in the doctrine of yin-yang in Chinese philosophy. Second, his theorizing demonstrates a bold intellectual innovation with (...) regard to Peircean semiotics. In short, the article exemplifies what highly relevant, and succinct, semiotic modeling looks like. (shrink)

This article argues that reality and virtuality are still very much phenomenologically distinguishable, although this might not be the case forever. I argue for two main types of virtuality – one inherently involved in the dynamic horizons of perceptual experiences, while the other is all of our experiences of digital images – in order to show that a particular possible instantiation of the latter type, namely “pure” mixed reality (MR), might come to blur and collapse various experiential categories in the (...) future, not least real and irreal, like never before. To show this, there are three main sections. First, I outline my understanding of the two basic types of virtuality, as understood from a classical phenomenological analysis. Second, I give an account of the most important family of “virtual technologies” relevant to the question at hand, namely virtual, augmented and mixed reality (VR, AR and MR respectively) technologies. After homing in on MR, I explain what “pure” MR is and how, through tactile holograms, this might change even basic experiential distinctions going forward, and not necessarily for the better.

Walter Burley is the author of a treatise, entitled De primo et ultimo instanti, which is regarded as the most popular medieval work on the problem of assigning first and last instants of being to permanent things. In this paper, however, the author does not deal with this treatise directly. She looks instead at Burley’s Physics commentary to see how he applies the ideas presented in De primo et ultimo instanti to the solution of an Aristotelian puzzle about the ceasing (...) to be of the present instant. In Burley’s interpretation, the relevant question raised by the puzzle is whether the present instant ceases to be when it is or when it is not. While Aristotle’s argument quickly dismisses the first alternative as absurd, Burley defends it by appealing to the ‘expositions’ of sentences about ceasing. Given that the sentence ‘this instant ceases to be’ has two expositions— ‘this instant now is and immediately afterwards will not be’ or ‘this instant now is not and immediately beforehand was’ —Burley maintains that the sentence is true in exposition but not true in exposition, so that an instant ceases to be when it is and not when it is not.

The concept of authenticity as a predicate of performances of musical works is discussed in the context of the Western classical tradition.I claim that the concept of a performance of a musical work raises issues of relativity and indeterminacy, since its application is not completely free from music-historical contextuality and from considerations of aesthetic value.I challenge the argument for the necessity of authenticity in performance that eschews the problem of determining the extension of the concept authentic performance of a work' (...) by reducing the concept to that of the correct instantiation of that work.I suggest that the way the present socio-musical context defines the boundaries of correction and authenticity in performance derives from a balance, and a tension, between two types of interest in performance as an artistic practice: an interest in the performed work as the artistic product of its composer, which favours fidelity to the work; and an interest in the performance as the artistic product of the performer, which favours the latter's creative freedom.I argue for the relevance of certain moral obligations to composers on the part of performers, but also for the defeasible character of these obligations, thus blocking the view according to which historical authenticity is an absolute moral imperative.I distinguish personal authenticity, as creativity and sincerity on the part the performer, from historical authenticity, as the performance's faithfulness to the work performed, to its composer, or to the sound, performance practice or musical experience that were typical of the work's original context. I argue against the view that the historically authentic performance has an advantage over other kinds of performance in terms of propensity to generate more aesthetically successful results.The promotion of historical authenticity by the historically informed performance movement is analyzed as artistic ideology and practice. I conclude that the priority of historical authenticity is not a defensible artistic ideal, since it is ultimately incompatible with aesthetic priorities. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 64.4 (2003) 619-637 [Access article in PDF] Overcoming Gnosticism:Hans Jonas, Hans Blumenberg, and the Legitimacy of the Natural World Benjamin Lazier University of Chicago In 1984, about a decade before his own murder, the Romanian scholar of religion Ioan Culianu complained of a more widespread, if decidedly less grisly form of assault. 1 The gnostics, he declared in a moment of high jocularity, (...) had "taken hold of the whole world, and we were not aware of it. It is a mixed feeling of anxiety and admiration, since I cannot refrain myself from thinking that these alien body-snatchers have done a remarkable job indeed." 2Though offered in jest, Culianu's designation "alien body-snatchers" quite accurately sums up what has remained since 1934 the leading view of gnosticism as a delimited, identifiable phenomenon. In that year appeared the first monumental volume of Gnosis und spätantiker Geist (Gnosis and the Spirit of Late Antiquity) composed by the young Jewish philosopher Hans Jonas as a dissertation under Martin Heidegger and the theologian Rudolf Bultmann. Over the next sixty years Jonas returned again and again to the movement as he defined it. Above all, gnosticism had as its guiding principle the notion of das Fremde. The term includes in its linguistic domain not only "the alien," by which it is most usually translated, but its cognates as well: the strange, the foreign, the other, the unknown, the uncanny, and the like. This sense of alienation is wildly overdetermined in gnostic theology: man is alienated from himself, from a fully transcendent God, and most powerfully from the material, [End Page 619] sensuous universe in which he lives, created as it was by an evil, malicious demiurge. Such anti-cosmism could license both ascetic retreat from the world as well as an antinomian descent into the worldly abyss, with the intent to defeat it from within. The locution "body-snatcher" now acquires relevance, for gnostic theology made impossible any positive appraisal of the physical body, or of the physical world at all for that matter. As the political philosopher Leo Strauss put it in a letter to Jonas, gnosticism may well have been the most radical rebellion in Western history against the Greek notion of physis.In stylized terms Jonas's philosophical career represents what I would like to call gnosticism's "third overcoming." Such terms signal an allegiance to the work of the German philosopher Hans Blumenberg. But they signal a departure as well. In Legitimität der Neuzeit (Legitimacy of the Modern Age, 1966), Blumenberg undertook what must count among the most ambitious revisions of Western intellectual history ever ventured. Against a rash of attacks on the modern age as an ill-concealed, secularized derivative of an earlier Christian era, he stepped up in its defense. He linked the emergence of the modern age—defined preeminently by man's need for self-assertion, to act in the world—to a "second overcoming" of gnosticism at the end of the Middle Ages. The gnostic spirit he found revived by the nominalism and theological voluntarism of late-medieval scholastic theology, a loose confluence of thought centripetally bound by the black hole of the deus absconditus or hidden god. Whereas gnosticism's first overcoming was Augustine's work and but a partial success, its second, and for Blumenberg "final" overcoming was the work of an ethos of human self-assertion best instantiated by the scientific program of Francis Bacon.To argue for its third overcoming in the late 1920s and '30s is therefore to take leave of Blumenberg's account, if also to extend it. The condition for the possibility of this argument, of course, is that gnosticism had in fact returned. Gnosticism, or at the very least a host of phenomena going by the name and generally understood as such, did indeed return, and with a vengeance—on the occult scene, in philosophy, in theology of all persuasions, even in natural-scientific discourse. This period also witnessed the return of the... (shrink)

This paper investigates whether empirical findings on how humans evaluate arguments in reinstatement cases support the ‘fewer attackers is better’ principle, incorporated in many current gradual notions of argument acceptability. Through three variations of an experiment, we find that (1) earlier findings that reinstated arguments are rated lower than when presented alone are replicated, (2) ratings at the reinstated stage are similar if all arguments are presented at once, compared to sequentially, and (3) ratings are overall higher if participants are (...) provided with the relevant theory, while still instantiating imperfect reinstatement. We conclude that these findings could at best support a more specific principle ‘being unattacked is better than attacked’, but alternative explanations cannot yet be ruled out. More generally, we highlight the danger that experimenters in reasoning experiments interpret examples differently from humans. Finally, we argue that more justification is needed on why, and how, empirical findings on how humans argue can be relevant for normative models of argumentation. (shrink)

ABSTRACTIn Democracy for Realists, Christopher Achen and Larry Bartels argue that voters are shortsighted and punish incumbents for politically irrelevant outcomes. These failings, in the authors’ view, mean that voters are incapable of holding politicians to account. But Achen and Bartels overstate voters’ failure to engage in effective retrospective voting. The authors also understate the degree to which accountability can be compatible with voters’ being myopic, such as when early- and late-term performance are correlated. Achen and Bartels also overlook evidence (...) that the American state acted as an insurer against social risk long before the New Deal, a fact that points to voters using relevant criteria when they appear to punish incumbents for natural disasters. Finally, while accountability is an important consequentialist reason for democracy, we should keep in mind non-consequentialist justifications for this system of government, in particular its instantiation of political equality.

The aim of this paper is to define a notion of supervenience which can adequately describe the systematic dependence of extrinsic as well as of intrinsic higher-level properties on base-level features. We argue that none of the standard notions of supervenience—the concepts of weak, strong and global supervenience—fulfil this function. The concept of regional supervenience, which is purported to improve on the standard conceptions, turns out to be problematic as well. As a new approach, we develop the notion of property-dependent (...) supervenience. This notion is founded on a criterion of relevance adapting the supervenience base to the considered higher-level properties in a specific way, such that only features which are relevant to the instantiation of the higher-level properties under consideration are taken into account.
