A number of concerns have been raised about the possible future use of pharmaceuticals designed to enhance cognitive, affective, and motivational processes, particularly where the aim is to produce morally better decisions or behavior. In this article, we draw attention to what is arguably a more worrying possibility: that pharmaceuticals currently in widespread therapeutic use are already having unintended effects on these processes, and thus on moral decision making and morally significant behavior. We review current evidence on the moral effects (...) of three widely used drugs or drug types: propranolol, selective serotonin reuptake inhibitors, and drugs that effect oxytocin physiology. This evidence suggests that the alterations to moral decision making and behavior caused by these agents may have important and difficult-to-evaluate consequences, at least at the population level. We argue that the moral effects of these and other widely used pharmaceuticals warrant further empirical research and ethical analysis. (shrink)

The goal of this article is to present a first list of ethical concerns that may arise from research and personal use of virtual reality (VR) and related technology, and to offer concrete recommendations for minimizing those risks. Many of the recommendations call for focused research initiatives. In the first part of the article, we discuss the relevant evidence from psychology that motivates our concerns. In Section “Plasticity in the Human Mind,” we cover some of the main results suggesting that (...) one’s environment can influence one’s psychological states, as well as recent work on inducing illusions of embodiment. Then, in Section “Illusions of Embodiment and Their Lasting Effect,” we go on to discuss recent evidence indicating that immersion in VR can have psychological effects that last after leaving the virtual environment. In the second part of the article, we turn to the risks and recommendations. We begin, in Section “The Research Ethics of VR,” with the research ethics of VR, covering six main topics: the limits of experimental environments, informed consent, clinical risks, dual-use, online research, and a general point about the limitations of a code of conduct for research. Then, in Section “Risks for Individuals and Society,” we turn to the risks of VR for the general public, covering four main topics: long-term immersion, neglect of the social and physical environment, risky content, and privacy. We offer concrete recommendations for each of these 10 topics, summarized in Table 1. (shrink)

In this article we revisit a number of disputes regarding significance logics---i.e., inferential frameworks capable of handling meaningless, although grammatical, sentences---that took place in a series of articles most of which appeared in the Australasian Journal of Philosophy between 1966 and 1978. These debates concern (i) the way in which logical consequence ought to be approached in the context of a significance logic, and (ii) the way in which the logical vocabulary has to be modified (either by restricting some notions, (...) or by adding some vocabulary) to keep as much of Classical Logic as possible. Our aim is to show that the divisions arising from these disputes can be dissolved in the context of a novel and intuitive proposal that we put forward. (shrink)

The terms `endurance' and `perdurance' are commonly thought to denote distinct ways for an object to persist, but it is surprisingly hard to say what these are. The common approach, defining them in terms of temporal parts, is mistaken, because it does not lead to two coherent philosophical alternatives: endurance so understood becomes conceptually incoherent, while perdurance becomes not just true but a conceptual truth. Instead, we propose a different way to articulate the distinction, in terms of identity rather than (...) temporal parts: an object endures if its identity is determined at every moment at which it exists. We make precise what it means for the identity of an object to be determined at a moment. We also discuss what role the endurance / perdurance distinction, so understood, should play in the debates about time, material objects and personal identity. (shrink)

Response to commentary. We are grateful to Crockett and Craigie for their interesting remarks on our paper. We accept Crockett’s claim that there is a need for caution in drawing inferences about patient groups from work on healthy volunteers in the laboratory. However, we believe that the evidence we cited established a strong presumption that many of the patients who are routinely taking a medication, including many people properly prescribed the medication for a medical condition, have morally significant aspects of (...) their cognition and behavior modified in a way that is unintended and may sometimes be unwelcome. Crockett notes that in some cases the effects of long-term drug use may differ, sometimes markedly, from the effects of short-term use. However, if acute use of a drug affects a neural system involved in mediating moral cognition or behavior, this nevertheless provides some evidence that chronic use of the drug may affect that same system and thus have morally significant effects. It is also plausible, in some cases, that an acute moral effect would give rise to a chronic moral effect via cognitive mechanisms. ... (shrink)

This article evaluates the effects of two types of rewards (performance-contingent versus engagement-contingent) on self-regulation, intrinsic motivation and creativity. Forty-two undergraduate students were randomly assigned to three conditions; i.e. a performance-contingent reward group, an engagement-contingent reward group and a control group. Results provide little support for the negative effects of performance rewards on motivational components. However, they do indicate that participants in the engagement-contingent reward group and the control group achieved higher rated creativity than participants in the performance-contingent reward group. (...) Alternative explanations for this finding are discussed. (shrink)

Much disease and disability is the result of lifestyle behaviours. For example, the contribution of imprudence in the form of smoking, poor diet, sedentary lifestyle, and drug and alcohol abuse to ill-health is now well established. More importantly, some of the greatest challenges facing humanity as a whole – climate change, terrorism, global poverty, depletion of resources, abuse of children, overpopulation – are the result of human behaviour. In this chapter, we will explore the possibility of using advances in the (...) cognitive sciences to develop strategies to intentionally manipulate human motivation and behaviour. While our arguments apply also to improving prudential motivation and behaviour in relation to health, we will focus on the more controversial instance: the deliberate targeted use of biomedicine to improve moral motivation and behaviour. We do this because the challenge of improving human morality is arguably the most important issue facing humankind (Persson and Savulescu, forthcoming). We will ask whether using the knowledge from the biological and cognitive sciences to influence motivation and behaviour erodes autonomy and, if so, whether this makes it wrong. (shrink)

In a recent paper, Max Deutsch argues that there is no “qua problem” for purely causal theories of reference, according to which the extensions of some expressions are grounded in causal relations to members of their extensions during dubbing acts. The qua problem is the difficulty in specifying the facts in virtue of which the reference of “elephant” is grounded by causal contact with something _qua_ elephant and not _qua_ its other properties. If no such specification can be given, reference (...) remains unacceptably indeterminate. This has led many to abandon purely causal reference grounding. Deutsch’s argument for the dissolution of the problem goes as follows: we usually agree that an event can cause its effect _qua_ some of its properties and not _qua_ others. For example, a hot acidic solution causes a glass beaker to break due to its heat and not due to its acidity. Given this assumption, we can simply say that an event caused a dubbing act _qua_ the causally relevant property and not _qua_ the causally irrelevant properties, thus grounding the reference of the term; the qua problem has vanished. I will argue that causal mechanisms, and in particular the facts about causal relevance appealed to by Deutsch, are insufficient to dissolve the qua problem. It is not generally the case that a _unique_ property is causally relevant in purely physical cases of causation; but this is precisely what is required to avoid the referential indeterminacy highlighted by the qua problem. I will demonstrate that if we rely on causal relevance to dissolve the qua problem, there is no way to respect the uniqueness requirement: there are too many properties that are causally relevant to the occurrence of any single dubbing act, including the intentional states of the dubber.

Open Peer Commentary, referring to "Neuroethics at 15: The Current and Future Environment for Neuroethics".

In this paper I argue that Marxist Buddhism may provide a novel approach to envy in society. It has been argued that envy arises in response to socio-political inequality, which is considered a problem given the social and moral harms associated with envy. Thus, achieving equality is expected to solve the problem of envy. However, anecdotal and empirical evidence suggests that is not the case, and that, in particular, societies inspired by Marxist ideals are not envy-free—if anything, the opposite seems (...) true. Buddhism has traditionally condemned envy. It shares with Marxism the idea that individual wellbeing can be obtained, paradoxically, only through lessening emphasis on individuality—Marxism by means of economic collectivism, Buddhism by means of a spiritual transformation. Both aim at shrinking the self and are keenly aware of how quickly an emphasis on one’s own desires leads to greed and exploitation of others. However, Marxist ideals have failed to yield successful large-scale flourishing communities, while Buddhism is a religion practiced by millions of people but has not advanced a politically progressive agenda in particular. Marxist Buddhism—argue—may perhaps bring together the best of the respective traditions to solve the problem of envy. However, I end by cautioning against such a radical reshaping of our psychological makeup, especially given the evidence that shows that there are morally and prudentially good types of envy, and sketch the profile of a Buddhist-friendly type of envy as an alternative to total eradication.

The debate on love's reasons ignores unrequited love, which—I argue—can be as genuine and as valuable as reciprocated love. I start by showing that the relationship view of love cannot account for either the reasons or the value of unrequited love. I then present the simple property view, an alternative to the relationship view that is beset with its own problems. In order to solve these problems, I present a more sophisticated version of the property view that integrates ideas from (...) different property theorists in the love literature. However, even this more sophisticated property view falls short in accounting for unrequited love's reasons. In response, I develop a new version of the property view that I call the experiential view. On this view, we love a person not only in virtue of properties shaped by and experienced in a reciprocal loving relationship, but also in virtue of perspectival properties, whose value can be properly assessed also outside of a reciprocal loving relationship. The experiential view is the only view that can account not only for reciprocated love's reasons, but also for unrequited love's reasons. (shrink)

The authors respond to a wide range of objections defending our argument that some forms of behaviour modification utilising advances in the cognitive sciences are desirable and need not necessarily undermine autonomy or freedom.

This paper develops and articulates a metaphysics of intersectionality, the idea that multiple axes of social oppression cross-cut each other. Though intersectionality is often described through metaphor, theories of intersectionality can be formulated using the tools of contemporary analytic metaphysics. A central tenet of intersectionality theory, that intersectional identities are inseparable, can be framed in terms of explanatory unity. Further, intersectionality is best understood as metaphysical and explanatory priority of the intersectional category over its constituents, akin to metaphysical priority of (...) the whole over its parts.

In juxtaposition with the myth and tragedy of Ovid’s Medea, this paper investigates the possibility within the Kantian conception of agency of understanding moral evil as acting against one’s better judgment. It defends the thesis that in Kant self-deception, i. e. the intentional untruthfulness to oneself, provides the fundamental structure for choosing against the moral law. I argue that, as Kant’s thought progresses, self-deception slowly proceeds to become the paradigmatic case of moral evil. This is discussed with regard to two (...) important topics in his later moral philosophy: the doctrine of radical evil and the crucial role of the duty of truthfulness in ethics. The inquiry into Kant’s theory of conscience unfolds both against this theoretical background and in light of its historical roots in the polemic against casuistry and probabilism. This contribution closes with a brief look at the tools Kant implements to counter this tendency to self-deception in moral judgment and particularly at the role casuistry plays within his conception of moral education.

Proponents of grounding often describe the notion as "metaphysical causation" involving determination and production relations similar to causation. This paper argues that the similarities between grounding and causation are merely superficial. I show that there are several sorts of causation that have no analogue in grounding; that the type of "bringing into existence" that both involve is extremely different; and that the synchronicity of ground and the diachronicity of causation make them too different to be explanatorily intertwined.

Introduction to alternative ontology of mind and physics based on the multi-dimensional model of A Geometric Theory of the Universe (Holster).

Science continually contributes new models and rethinks old ones. The way inferences are made is constantly being re-evaluated. The practice and achievements of science are both shaped by this process, so it is important to understand how models and inferences are made. But, despite the relevance of models and inference in scientific practice, these concepts still remain contro-versial in many respects. The attempt to understand the ways models and infer-ences are made basically opens two roads. The first one is to (...) produce an analy-sis of the role that models and inferences play in science. The second one is to produce an analysis of the way models and inferences are constructed, especial-ly in the light of what science tells us about our cognitive abilities. The papers collected in this volume go both ways. (shrink)

In this paper I present a novel taxonomy of envy, according to which there are four kinds of envy: emulative, inert, aggressive and spiteful envy. An inquiry into the varieties of envy is valuable not only to understand it as a psychological phenomenon, but also to shed light on the nature of its alleged viciousness. The first section introduces the intuition that there is more than one kind of envy, together with the anecdotal and linguistic evidence that supports it. The (...) second section proposes and explains in detail a definition of envy tout court. The third section presents a recurring distinction between behavioral tendencies of envy, which has been explained in two distinct ways, one mostly proposed by psychologists, the other discernible in the philosophical tradition. The fourth section argues that these models of explanation track two variables, whose interplay is responsible for the existence of the four envies. The fifth section illustrates four paradigmatic cases, and provides a detailed analysis of the phenomenology, motivational structure, and typical behavioral outputs of each. The paper ends with a brief discussion of the implications of the taxonomy for moral education. (shrink)

Widespread causal overdetermination is often levied as an objection to nonreductive theories of minds and objects. In response, nonreductive metaphysicians have argued that the type of overdetermination generated by their theories is different from the sorts of coincidental cases involving multiple rock-throwers, and thus not problematic. This paper pushes back. I argue that attention to differences between types of overdetermination discharges very few explanatory burdens, and that overdetermination is a bigger problem for the nonreductive metaphysician than previously thought.

Debates over what is fundamental assume that what is most fundamental must be either a “top” level (roughly, the biggest or highest-level thing), or a “bottom” level (roughly, the smallest or lowest-level things). Here I sketch an alternative to top-ism and bottom-ism, the view that a middle level could be the most fundamental, and argue for its plausibility. I then suggest that the view satisfies the desiderata of asymmetry, irreflexivity, transitivity, and well-foundedness of fundamentality, that the view has explanatory power (...) on par with that of top-ism and bottom-ism, and that it satisfies the Principle of Sufficient Reason.

Introduction au Numéro spécial de la Revue Philosophique de Louvain.

We argue that least-developed countries (LDCs) should be treated as a distinct group from developing countries within theories of global justice generally, and theories of trade justice more specifically. While authors within the trade justice literature occasionally make passing reference to LDCs’ entitlement to special favourable treatment from other states, little is said about what form this treatment should take, and how such entitlements relate to the obligations and entitlements of both developed and developing countries. This oversight is untenable in (...) that it neglects the different character and urgency of LDCs’ needs with respect to the economic opportunities afforded to them in international markets. Moreover, by categorising trading states into binary categories of developed/developing or rich/poor, trade justice theorists have ended up obscuring and passing over unavoidable conflicts between least-developed and developing countries’ interests, the weighing of which should be central to any complete normative evaluation of the trade regime. We provide an example of such a conflict of interest and how it should be resolved by examining the structural barrier to LDC economic development presented by the current success of many developing countries in export manufacturing. We argue in favour of a trade policy intervention that would dismantle this structural barrier (by inducing export firms to move to LDCs), even though this means diverting valuable economic opportunities from developing countries.

This paper argues that several sorts of metaphysical and semantic indeterminacy afflict the causal relation. If, as it is plausible to hold, there is a relationship between causation and moral responsibility, then indeterminacy in the causal relation results in indeterminacy of moral responsibility more generally.

Das Konzept der Abwägung wird in der praktischen Philosophie ebenso ubiquitär verwendet wie in den Wirtschaftswissenschaften und im Recht. Es ist jedoch voraussetzungsvoller und umstrittener als zumeist angenommen. „Abwägung“ bezeichnet einen Vorgang praktischen Überlegens, in den mehrere Aspekte in vergleichender Weise eingehen. Die Skepsis gegen das Konzept gründet darin, dass sich die Metapher nicht auf beliebige Gegenstände anwenden lässt. Insbesondere müssen die Wertzuschreibungen, die das Gewicht der Gegenstände bestimmen, in ihren normativen Grundlagen widerspruchsfrei sein und sie müssen ähnlich wie die (...) Gewichtskräfte, mit denen Körper auf die Schalen einer Balkenwaage einwirken, eine gewisse Kontextinvarianz aufweisen. Das setzt Unabhängigkeitsannahmen voraus, deren Gültigkeit im Falle normativer Bewertungen nicht trivial ist. Der Band dient dem Zweck, diese Zusammenhänge durchsichtiger zu machen. Er entstand auf der Basis einer mehrjährigen Zusammenarbeit von Autor:innen aus den Fächern Philosophie, Jurisprudenz und Ökonomie. (shrink)

This paper gives a framework for understanding causal counterpossibles, counterfactuals imbued with causal content whose antecedents appeal to metaphysically impossible worlds. Such statements are generated by omissive causal claims that appeal to metaphysically impossible events, such as “If the mathematician had not failed to prove that 2+2=5, the math textbooks would not have remained intact.” After providing an account of impossible omissions, the paper argues for three claims: (i) impossible omissions play a causal role in the actual world, (ii) causal (...) counterpossibles have broad applications in philosophy, and (iii) the truth of causal counterpossibles provides evidence for the nonvacuity of counterpossibles more generally.

This paper poses an original puzzle about the relationship between causation and moral responsibility called The Moral Difference Puzzle. Using the puzzle, the paper argues for three related ideas: (1) the existence of a new sort of moral luck; (2) an intractable conflict between the causal concepts used in moral assessment; and (3) inability of leading theories of causation to capture the sorts of causal differences that matter for moral evaluation of agents’ causal contributions to outcomes.

In "Changing the Past" (2010), Peter van Inwagen argues that a time traveler can change the past without paradox in a growing block universe. After erasing the portion of past existence that generates paradox, a new, non-paradox-generating block can be "grown" after the temporal relocation of the time traveler. -/- I articulate and explore the underlying mechanism of Van Inwagen's model: the time traveler's control over the location of the objective present. Van Inwagen's model is aimed at preventing paradox by (...) changing the past, but it achieves something broader than paradox avoidance: it gives tools for a new model of time travel. I use van Inwagen's tools to develop a new kind of time travel in which in which the location of the objective present is shifted by the time traveler. I call this type of time travel Movable Objective Present, or MOP. After defining MOP, I argue that it is compatible with any theory of time that accepts hypertime, including presentism and moving spotlight theory. (shrink)

Theories of causation grounded in counterfactual dependence face the problem of profligate omissions: numerous irrelevant omissions count as causes of an outcome. A recent purported solution to this problem is proportionality, which selects one omission among many candidates as the cause of an outcome. This paper argues that proportionality cannot solve the problem of profligate omissions for two reasons. First: the determinate/determinable relationship that holds between properties like aqua and blue does not hold between negative properties like not aqua and (...) not blue. Negative properties are those at stake in omissive causation. Second: proportionality misconstrues the nature of the problem to be solved. (shrink)

I argue for the view that envy and jealousy are distinct emotions, whose crucial difference is that envy involves a perception of lack while jealousy involves a perception of loss. I start by noting the common practice of using ‘envy’ and ‘jealousy’ almost interchangeably, and I contrast it with the empirical evidence that shows that envy and jealousy are distinct, albeit similar and often co-occurring, emotions. I then argue in favor of a specific way of understanding their distinction: the view (...) that envy is a response to a perceived lack of a valuable object, while jealousy is a response to a perceived loss of a valuable object. I compare such a view with the most compelling alternative theories, and show that it accounts better for paradigmatic cases. I conclude by showing how the lack vs. loss model can handle complications: ambiguous cases, that is, when it is epistemically unclear whether one experiences lack or loss; hybrid cases, that is, when one seems to experience both lack and loss; and borderline cases, that is, when it is metaphysically unclear whether one experiences lack or loss.

This paper discusses a puzzling tension in attributions of moral responsibility in cases of resultant moral luck: we seem to hold agents fully morally responsible for unlucky outcomes, but less-than-fully-responsible for unlucky outcomes brought about differently than intended. This tension cannot be easily discharged or explained, but it does shed light on a famous puzzle about causation and responsibility, the Thirsty Traveler.

I present and develop the view that omissions are de re possibilities of actual events. Omissions do not literally fail to occur; rather, they possibly occur. An omission is a tripartite metaphysical entity composed of an actual event, a possible event, and a contextually specified counterpart relation between them. This view resolves ontological, causal, and semantic puzzles about omissions, and also accounts for important data about moral responsibility for outcomes resulting from omissions.

In this paper, I ask whether there is a defensible philosophical view according to which everybody is beautiful. I review two purely aesthetical versions of this claim. The No Standards View claims that everybody is maximally and equally beautiful. The Multiple Standards View encourages us to widen our standards of beauty. I argue that both approaches are problematic. The former fails to be aspirational and empowering, while the latter fails to be sufficiently inclusive. I conclude by presenting a hybrid ethical–aesthetical (...) view according to which everybody is beautiful in the sense that everybody can be perceived through a loving gaze. I show that this view is inclusive, aspirational and empowering, and authentically aesthetical. (shrink)

I argue that fitting envy plays a special role in safeguarding our happiness and flourishing. After presenting my theory of envy and its fittingness conditions, I contrast Kant’s view that envy is always unfitting with D’Arms and Jacobson’s defense of fitting envy as an evolutionarily-shaped response to a deep and wide human concern, that is, relative positioning. However, D’Arms and Jacobson don’t go far enough. First, I expand on their analysis of positional goodness, distinguishing between an epistemic claim, according to (...) which we use implicit or explicit comparison to know what position we occupy in a continuum of goodness, and thus to form judgments of goodness, and a metaphysical one, according to which much human goodness depends on implicit or explicit rankings and positionality. Second, I argue that fitting envy is not only intrinsically valuable qua fitting response to authentic goodness, but can be epistemically, morally and prudentially valuable. (shrink)

Episodic and semantic memory are often taken to be fundamentally different mental systems, and contemporary philosophers often pursue research questions about episodic memory, in particular, in isolation from semantic memory. This paper challenges that assumption, and puts pressure on philosophical approaches to memory that break off episodic memory as its own standalone topic. I present and systematize psychological and neuroscientific theories of semanticization, the thesis that memory content tends to drift from episodic to semantic in structure over time and exposure (...) to an environment. Semanticization, I argue, is a long-term interconnection between episodic and semantic systems that requires approaching both the content and function of these two memory systems as a whole. Thus we have a reason to reject projects by Michael Martin, which aims to carve out a uniquely episodic memory content, and Kourken Michaelian, which pairs episodic memory to its own unique function. Instead, seeing declarative memory as a single system with two facets or even a continuum of features allows for deeper insight into both content and function. (shrink)

Many philosophers hypothesize that our concept of personal identity is partly constituted by the one-person-one-place rule, which states that a person can only be in one place at a time. This hypothesis has been assumed by the most influential contemporary work on personal identity. In this paper, we report a series of studies testing whether the hypothesis is true. In these studies, people consistently judged that the same person existed in two different places at the same time. This result undermines (...) some widely held philosophical assumptions, supports others, and fits well with recent discoveries on identity judgments about inanimate objects and non-human animals.

The social categories to which we belong—Latino, disabled, American, woman— causally influence our lives in deep and unavoidable ways. One might be pulled over by police because one is Latino, or one might receive a COVID vaccine sooner because one is American. Membership in these social categories most often falls outside of our control. This paper argues that membership in social categories constitutes a restriction on human agency, creating a situation of non-ideal agency for many human individuals. -/- However, there (...) are ways to resist the causal influence of social categories, and certain socially marginalized groups can be understood as attempting to do just this. I discuss two instances of social category resistance: gender pronouns and the rights of trans individuals. I suggest that the intentional declaration of gender pronouns (“she/her” or “they/them”) can be understood as an attempt to resist the causal powers of nonconsensual social categorization. Similarly, one among many reasons to support the rights of trans individuals is that their self-declarations of gender identity can be viewed as a reclamation of agency in the face of causal constraints imposed by socially defined and imposed gender categories. This lesson can be generalized to people belonging to a broad range of marginalized groups. (shrink)

Living with chronic illness can involve fluctuating between radically different bodily states depending on whether you are experiencing flareups of illness symptoms. What you can do in these bodily states can differ drastically from one another. Sometimes, these fluctuations in abilities lead to fluctuations in your values. That is, your evaluative perspective can shift when you are experiencing flareups of the illness. This can give rise to a puzzle for planning, since it is unclear what you should plan on doing (...) when you do not have a stable set of preferences guiding your plans. This paper argues that one way to navigate this puzzle is for the agent to adopt an overarching plan that mediates the conflict between her differing perspectives. (shrink)

In this chapter, I argue that a certain kind of envy is not only morally permissible, but also, sometimes, more fitting and productive than admiration. Envy and admiration are part of our emotional palette, our toolbox of evolutionary adaptations, and they play complementary roles. I start by introducing my original taxonomy of envy, which allows me to present emulative envy, a species of envy sometimes confused with admiration. After reviewing how the two emotions differ from a psychological perspective, I focus (...) in particular on the distinct and complementary roles they play in the ethical and political domains.

This article explores the usefulness of interdisciplinarity as method of enquiry by proposing an investigation of the concept of information in the light of semiotics. This is because, as Kull, Deacon, Emmeche, Hoffmeyer and Stjernfelt state, information is an implicitly semiotic term (Biological Theory 4(2):167–173, 2009: 169), but the logical relation between semiosis and information has not been sufficiently clarified yet. Across the history of cybernetics, the concept of information undergoes an uneven development; that is, information is an ‘objective’ entity (...) in first order cybernetics, and becomes a ‘subjective’ entity in second order cybernetics. This contradiction relegates the status of information to that of a ‘true’ or ‘false’ formal logic problem. The present study proposes that a solution to this contradiction can be found in Deely’s reconfiguration of Peirce’s ‘object’ (as found in his triadic model of semiosis) into ‘thing’ and ‘object’ (Deely 1981). This ontology allows one to argue that information is neither ‘true’ nor ‘false’, and to suggest that, when considered in light of its workability, information can be both true and false, and as such it constitutes an organism’s purely objective reality (Deely 2009b). It is stated that in the process of building such a reality, information is ‘motivated’ by environmental, physiological, emotional (including past feelings and expectations) constraints which are, in turn, framed by observership. Information is therefore found in the irreducible cybersemiotic process that links at once all these conditions and that is simultaneously constrained by them. The integration of cybernetics’ and semiotics’ understanding of information shows that history is the analytical principle that grants scientific rigour to interdisciplinary investigations. As such, in any attempt to clarify its epistemological stance (e.g. the semiotic aspect of information), it is argued that biosemiotics does not need only to acknowledge semiotics (as it does), but also cybernetics in its interdisciplinary heritage.

In this paper I will show the problems that are encountered when dealing with uniqueness of connectives in a bilateralist setting within the larger framework of proof-theoretic semantics and suggest a solution. Therefore, the logic 2Int is suitable, for which I introduce a sequent calculus system, displaying - just like the corresponding natural deduction system - a consequence relation for provability as well as one dual to provability. I will propose a modified characterization of uniqueness incorporating such a duality of (...) consequence relations, with which we can maintain uniqueness in a bilateralist setting. (shrink)

The work of Thomas White represents a systematic attempt to combine the best of the new science of the seventeenth century with the best of Aristotelian tradition. This attempt earned him the criticism of Hobbes and the praise of Leibniz, but today, most of his attempts to navigate between traditions remain to be explored in detail. This paper does so for his ontology of accidents. It argues that his criticism of accidents in the category of location as entities over (...) and above substances was likely aimed at Francisco Suárez, and shows how White’s worries about the analysis of location were linked with his broader cosmological views. White rejects real qualities, but holds that the quantity of a substance is somehow distinct from its bearer. This reveals a common ground with some of his scholastic interlocutors, but lays bare a deep disagreement with thinkers like Descartes on the nature of matter. (shrink)

This is Part 1 of a four part paper, intended to redress some of the most fundamental confusions in the subject of physical time directionality, and represent the concepts accurately. There are widespread fallacies in the subject that need to be corrected in introductory courses for physics students and philosophers. We start in Part 1 by analysing the time reversal symmetry of quantum probability laws. Time reversal symmetry is defined as the property of invariance under the time reversal transformation, T: (...) t --> -t. It is shown that quantum mechanics (classical or relativistic) is strongly time asymmetric in its probability laws. This contradicts the orthodox analysis, found throughout the conventional literature on physical time, which claims that quantum mechanics is time symmetric or reversible. This is widely claimed as settled scientific fact, and large philosophical and scientific conclusions are drawn from it. But it is an error. The fact is that while quantum mechanics is widely claimed to be reversible on the basis of two formal mathematical properties (that it does have), these properties do not represent invariance under the time reversal transformation. A recent experiment (Batalhão at alia, 2015) showing irreversibility of quantum thermodynamics is discussed as an illustration of this result. Most physicists remain unaware of the errors, decades after they were first demonstrated. Orthodox specialists in the philosophy of time who are aware of the error continue to refer to the ‘time symmetry’ or ‘reversibility’ of quantum mechanics anyway – and exploit the ambiguity to claim false implications about physical time reversal symmetry in nature. The excuse for perpetrating the confusion is that, since it is has now become customary to refer to the formal properties of quantum mechanics as ‘reversibility’ or ‘time reversal symmetry’, we should just keep referring to them by this name, even though they are not time reversal symmetry. This causes endless confusion, in attempts to explain the physical irreversibility of our universe, and in philosophical discussions of implications of physics for the nature of time. The failure of genuine time reversal symmetry in quantum mechanics changes the interpretation of modern physics in a deep way. It changes the problem of explaining the real irreversibility found throughout nature. (shrink)

This paper argues that so-called “trumping preemption” is in fact overdetermination or early preemption, and is thus not a distinctive form of redundant causation. I draw a novel lesson from cases thought to be trumping: that the boundary between preemption and overdetermination should be reconsidered.

People often answer why-questions with what we call experiential explanations: narratives or stories with temporal structure and concrete details. In contrast, on most theories of the epistemic function of explanation, explanations should be abstractive: structured by general relationships and lacking extraneous details. We suggest that abstractive and experiential explanations differ not only in level of abstraction, but also in structure, and that each form of explanation contributes to the epistemic goals of individual learners and of science. In particular, experiential explanations (...) support mental simulation and survive transitions across background theories; as a result, they support learning and help us translate between competing frameworks. Experiential explanations play an irreducible role in human cognition – and perhaps in science. (shrink)
