It is surprisingly hard to define presentism. Traditional definitions of the view, in terms of tensed existence statements, have turned out not to to be capable of convincingly distinguishing presentism from eternalism. Picking up on a recent proposal by Tallant, I suggest that we need to locate the break between eternalism and presentism on a much more fundamental level. The problem is that presentists have tried to express their view within a framework that is inherently eternalist. I call that framework (...) the Fregean nexus, as it is defined by Frege’s atemporal understanding of predication. In particular, I show that the tense-logical understanding of tense which is treated as common ground in the debate rests on this very same Fregean nexus, and is thus inadequate for a proper definition of presentism. I contrast the Fregean nexus with what I call the original temporal nexus, which is based on an alternative, inherently temporal form of predication. Finally, I propose to define presentism in terms of the original temporal nexus, yielding original presentism. According to original presentism, temporal propositions are distinguished from atemporal ones not by aspects of their content, as they are on views based on the Fregean nexus, but by their form—in particular, by their form of predication.

(Expected) adverse effects of the ‘ICT Revolution’ on work and opportunities for individuals to use and develop their capacities give a new impetus to the debate on the societal implications of technology and raise questions regarding the ‘responsibility’ of research and innovation (RRI) and the possibility of achieving ‘inclusive and sustainable society’. However, missing in this debate is an examination of a possible conflict between the quest for ‘inclusive and sustainable society’ and conventional economic principles guiding capital allocation (including the (...) funding of research and innovation). We propose that such conflict can be resolved by re-examining the nature and purpose of capital, and by recognising mainstream economics’ utilitarian foundations as an unduly restrictive subset of a wider Aristotelian understanding of choice.

We analyse Hutto & Myin's three arguments against computationalism [Hutto, D., E. Myin, A. Peeters, and F. Zahnoun.

The Hard Problem (...) of Content targets computationalism that relies on semantic notion of computation, claiming that it cannot account for the natural origins of content. The Intentionality Problem is targeted against computationalism using non-semantic accounts of computation, arguing that it fails in explaining intentionality. Theion Problem claims that causal interaction between concrete physical processes and abstract computational properties is problematic. We argue that these a... (shrink)

According to David Rosenthal’s higher-order thought (HOT) theory of consciousness, a mental state is conscious just in case one is aware of being in that state via a suitable HOT. Jesse Mulder (2016) recently objects: though HOT theory holds that conscious states are states that it seems to one that one is in, the view seems unable to explain how HOTs engender such seemings. I clarify here how HOT theory can adequately explain the relevant mental appearances, illustrating the (...) explanatory power of HOT theory. (shrink)

Nicholas Agar, Jeff McMahan and Allen Buchanan have all expressed concerns about enhancing humans far outside the species-typical range. They argue radically enhanced beings will be entitled to greater and more beneficial treatment through an enhanced moral status, or a stronger claim to basic rights. I challenge these claims by first arguing that emerging technologies will likely give the enhanced direct control over their mental states. The lack of control we currently exhibit over our mental lives greatly contributes to our (...) sense of vulnerability. I then argue moral status should be viewed in terms of vulnerability. The enhanced will slowly gain the ability to command their mental states, reducing their vulnerability. These radically enhanced beings will have greater capacities, and possibly an inner life more valuable than our own. They will also be less vulnerable, and as a result, their moral status will be subordinate to our own. (shrink)

Writers in the propositions literature consider the Benacerraf objection serious, often decisive. The objection figures heavily in dismissing standard theories of propositions of the past, notably set-theoretic theories. I argue that the situation is more complicated. After explicating the propositional Benacerraf problem, I focus on a classic set-theoretic theory of propositions, the possible worlds theory, and argue that methodological considerations influence the objection’s success.

Chalmers (Mind 120(479): 587–636, 2011a) presents an argument against “referentialism” (and for his own view) that employs Bayesianism. He aims to make progress in a debate over the objects of belief, which seems to be at a standstill between referentialists and non-referentialists. Chalmers’ argument, in sketch, is that Bayesianism is incompatible with referentialism, and natural attempts to salvage the theory, Chalmers contends, requires giving up referentialism. Given the power and success of Bayesianism, the incompatibility is prima facie evidence against referentialism. (...) In this paper, I review Chalmers’ arguments and give some responses on behalf of the referentialist. (shrink)

In response to Petitmengin and Bitbol's recent account of first-person methodologies in the study of consciousness, I provide a revised model of our introspective knowledge of our own conscious experience. This model, which I call the existential constitution model of phenomenal knowledge, avoids the problems that Petitmengin and Bitbol identify with standard observational models of introspection while also avoiding an underlying metaphorical misconception in their own proximity model, which misconstrues first-person knowledge of consciousness in terms of a dichotomous epistemic relationship. (...) The end result is a clearer understanding of the unique nature and epistemic properties of our knowledge of consciousness, as well as the epistemic status of subsequent first-person reports on conscious experience.

This paper demonstrates the practical and philosophical strengths of adopting Luciano Floridi’s “general definition of information” (GDI) for use in the information sciences (IS). Many definitions of information have been proposed, but little work has been done to determine which definitions are most coherent or useful. Consequently, doubts have been cast on the necessity and possibility of finding a definition. In response to these doubts, the paper shows how items and events central to IS are adequately described by Floridi’s conception (...) of information, and demonstrates how it helps clarify the muddy theoretical framework resulting from the many previous definitions. To this end, it analyzes definitions, popular in IS, that conceive of information as energy, processes, knowledge, and physical objects. The paper finds that each of these definitions produces problematic or counterintuitive implications that the GDI suitably accounts for. It discusses the role of truth in IS, notes why the GDI is preferable to its truth-requiring variant, and ends with comments about the import of such a theory for IS research and practice. (shrink)

What kind of mental phenomenon is romantic love? Many philosophers, psychologists, and ordinary folk treat it as an emotion. This chapter argues the category of emotion is inadequate to account for romantic love. It examines major emotion theories in philosophy and psychology and shows that they fail to illustrate that romantic love is an emotion. It considers the categories of basic emotions and emotion complexes, and demonstrates they too come short in accounting for romantic love. It assesses the roles of (...) culture and evolution in shaping the romantic love phenomenon and evaluates the ways in which the norms of rationality that are applied to standard emotions fail to apply to love. It considers the category of sentiments and argue that despite coming close, it does not adequately capture the nature of romantic love. Finally, the chapter makes a case for love being best characterized as a syndrome. (shrink)

Our computational metaphysics group describes its use of automated reasoning tools to study Leibniz’s theory of concepts. We start with a reconstruction of Leibniz’s theory within the theory of abstract objects (henceforth ‘object theory’). Leibniz’s theory of concepts, under this reconstruction, has a non-modal algebra of concepts, a concept-containment theory of truth, and a modal metaphysics of complete individual concepts. We show how the object-theoretic reconstruction of these components of Leibniz’s theory can be represented for investigation by means of automated (...) theorem provers and finite model builders. The fundamental theorem of Leibniz’s theory is derived using these tools. (shrink)

Past work has shown systematic differences between Easterners' and Westerners' intuitions about the reference of proper names. Understanding when these differences emerge in development will help us understand their origins. In the present study, we investigate the referential intuitions of English- and Chinese-speaking children and adults in the U.S. and China. Using a truth-value judgment task modeled on Kripke's classic Gödel case, we find that the cross-cultural differences are already in place at age seven. Thus, these differences cannot be attributed (...) to later education or enculturation. Instead, they must stem from differences that are present in early childhood. We consider alternate theories of reference that are compatible with these findings and discuss the possibility that the cross-cultural differences reflect differences in perspective-taking strategies.

Abstract: In this paper we argue that Robert Kane’s theory of free will cannot accommodate the possibility of a sinless individual who faces morally significant choices because a sinless agent cannot voluntarily accord value to an immoral desire, and we argue that Kane’s theory requires this. Since the Jesus of the historic Christian tradition is held to be sinless, we think Christians should reject Kane’s theory because it seems irreconcilable with historic Christian Christology. We consider two objections to our argument (...) and argue that both fail. (shrink)

If the goal of statistical analysis is to form justified credences based on data, then an account of the foundations of statistics should explain what makes credences justified. I present a new account called statistical reliabilism (SR), on which credences resulting from a statistical analysis are justified (relative to alternatives) when they are in a sense closest, on average, to the corresponding objective probabilities. This places (SR) in the same vein as recent work on the reliabilist justification of credences generally (...) [Dunn, 2015, Tang, 2016, Pettigrew, 2018], but it has the advantage of being action-guiding in that knowledge of objective probabilities is not required to identify the best-justified available credences. The price is that justification is relativized to a specific class of candidate objective probabilities, and to a particular choice of reliability measure. On the other hand, I show that (SR) has welcome implications for frequentist-Bayesian reconciliation, including a clarification of the use of priors; complemen- tarity between probabilist and fallibilist [Gelman and Shalizi, 2013, Mayo, 2018] approaches towards statistical foundations; and the justification of credences outside of formal statistical settings. Regarding the latter, I demonstrate how the insights of statistics may be used to amend other reliabilist accounts so as to render them action-guiding. I close by discussing new possible research directions for epistemologists and statisticians (and other applied users of probability) raised by the (SR) framework. (shrink)

In this short paper, we show that a popular view in information science, information-as-thing, fails to account for a common example of information that seems physical. We then demonstrate how the distinction between types and tokens, recently used to analyse Shannon information, can account for this same example by viewing information as abstract, and discuss existing definitions of information that are consistent with this approach. -/- Dans ce court article nous montrons qu'une vision populaire en sciences de l'information, l'information en (...) tant qu’une chose, échoue à rendre compte d'un exemple commun d'information qui semble physique. Nous démontrons ensuite comment la distinction type/token, utilisée récemment pour analyser l'information de Shannon, peut rendre compte de ce même exemple en considérant l'information comme abstraite, et nous discutons des définitions existantes de l’information qui sont compatibles avec cette approche.

In this position paper for the 2019 CSCW workshop Good Systems: Ethical AI for CSCW I propose one tool and one idea for navigating the complex ethical problem space that results from the interaction of human and/or AI agents in shared, hopefully cooperative, computing environments.

This paper will present two contributions to teaching introductory logic. The first contribution is an alternative tree proof method that differs from the traditional one-sided tree method. The second contribution combines this tree system with an index system to produce a user-friendly tree method for sentential modal logic.

Contemporary philosopher David Benatar has advanced the self-evidently controversial claim that “coming into existence is always a harm.” Benatar’s argument turns on the basic asymmetry between pleasure and pain, an asymmetry he seeks to explain by the principle that those who never exist cannot be deprived. Benatar’s import is almost incredible: humans should cease to procreate immediately, thereby engendering the extinction of the species—a view known as “anti-natalism.” According to many of his readers, the ancient Hebrew sage Qoheleth expresses a (...) pessimistic nihilism that runs as thick as Benatar’s. Prima facie grounding for this assertion is that Qoheleth, like Benatar, raises the issue of whether coming into existence may be a harm—and gives an affirmative answer. In two passages, Ecclesiastes 6:1-6 and 4:1-3, Qoheleth declares that an unborn hypothetical person is “better off” than their existent counterpart. Yet the meaning and implication of these words is far from obvious. Does Qoheleth imply that the non-exister’s state, and non-existence in general, is universally superior to existence? Or is he instead speaking exceptionally, of particular persons in rare circumstances? By examining the two “better”-statements in their literary context, I will argue that Qoheleth intends these examples as exceptions. He does not go so far as to make the supremely nihilistic claim that coming into existence is always, or even generally, a net harm; yet, he does concede that in certain cases, it can be. Beyond this, I will explore how the two thinkers’ divergent conclusions can be traced to a deeper difference of philosophical method. This question concerning non-existence opens a window to Qoheleth’s broader scheme of values and therefore serves as a surprisingly useful entry point by which to engage his philosophy. The paper utilizes the methodology Jaco Gericke has recently termed “philosophical criticism,” but specifically applied to Qoheleth. (shrink)

Philosophical lessons come in many different shapes and sizes. Some lessons are big, some are small. Some lessons go deep and have a big impact, some are shallow and have almost none. Some lessons are not really philosophical at all or would not really be lessons for an audience of academic philosophers. I mention these truisms not to disparage this informative book on 'moral OCD' (moral obsessive-compulsive disorder, or 'Scrupulosity') but rather to emphasize how difficult it can be to discern (...) the book's intended audience, given its interdisciplinary aims and structure. That question is never explicitly addressed (it is admittedly a slim book, slimmer than it appears), but the question has consequences for how to think about the book's ultimate value, and for whom. The book might attract two groups in particular: philosophers working on the nature of responsibility (the subject of the book's longest chapter) and psychiatric researchers or mental health professionals interested in moral philosophy and the philosophy of mental illness. I will return to what moral philosophers can learn from moral OCD, but there will be spoilers. (shrink)

Recently two distinct forms of rule-utilitarianism have been introduced that differ on how to measure the consequences of rules. Brad Hooker advocates fixed-rate rule-utilitarianism, while Michael Ridge advocates variable-rate rule-utilitarianism. I argue that both of these are inferior to a new proposal, optimum-rate rule-utilitarianism. According to optimum-rate rule-utilitarianism, an ideal code is the code whose optimum acceptance level is no lower than that of any alternative code. I then argue that all three forms of rule-utilitarianism fall prey to two fatal (...) problems that leave us without any viable form of rule-utilitarianism. (shrink)

This paper examines the complexity and fluidity of maternal identity through an examination of narratives about "real motherhood" found in children's literature. Focusing on the multiplicity of mothers in adoption, I question standard views of maternity in which gestational, genetic and social mothering all coincide in a single person. The shortcomings of traditional notions of motherhood are overcome by developing a fluid and inclusive conception of maternal reality as authored by a child's own perceptions.

Je défends ici la nécessité, et ébauche une première version, d’une théorie iconique des propositions. Selon celle-ci, les propositions sont comme les objets de représentation, ou similaires à eux. Les propositions, suivant cette approche, sont des propriétés que l’esprit instancie lorsqu’il modélise le monde. Je connecte cette théorie aux récents développements de la littérature académique sur les propositions, ainsi qu’à une branche de recherches en sciences cognitives, qui explique certains types de représentations mentales en termes d’iconicité. I motivate the need (...) for, and then sketch, an iconic theory of propositions according to which propositions are like or similar to their objects of representation. Propositions on this theory are properties that the mind instantiates when it models the world. I connect the theory to recent developments in the propositions literature as well as to a strain of cognitive science that explains some kinds of mental representation in terms of iconicity.

The nature-nurture debate rages so, one cannot help but wonder why the sides are so vehemently partitioned. What's at stake? It is simply not clear why a great amount of people embrace either one side or the other, but dare not even blow a kiss to the opposite opinion. Prinz does an excellent job of arguing for the nurture position, zeroing in on some of the most preciously held nature arguments including the basis of knowledge, thought, and feelings in experience (...) and cultural values, increasing as a child grows. Most prominent of the nature hypothèses that Prinz takes on may be that of language acquisition and the Chomskyean notion of inborn lingusitic knowledge, via the proposed universal language. He contends that children's language acquisition--even the notion that the supposed inborn language device shuts off somewhere in mid-childhood, meaning most people will not be fully bilingual--need not demand such a natural language faculty in the brain, as general learning strategies can account for language acquisition. His arguments can stimulate both nurturists and naturists. Yet, in the end--realizing how much of the human arise from the genes--one still cannot help wonder why the two debated positions so rally to one flag or the other. (shrink)

Panpsychism is the view that every concrete and unified thing has some form of phenomenal consciousness or experience. It is an age-old doctrine, which, to the surprise of many, has recently taken on new life. In philosophy of mind, it has been put forth as a simple and radical solution to the mind–body problem (Chalmers 1996, 2003;Strawson 2006; Nagel 1979, 2012). In metaphysics and philosophy of science, it has been put forth as a solution to the problem of accounting for (...) the intrinsic nature of the physical itself (Strawson 2006, Seager 2006). In this thesis, I show that panpsychism can also be defended on the basis of an argument from our (arguable) acquaintance with the nature of causation in agency. This argument has made frequent appearances throughout the history of philosophy, with philosophers such as Leibniz, Schopenhauer and James, and I construct and defend an updated version of it. Furthermore, I offer a solution to the combination problem: how can complex (human and animal-type) consciousness result from simple (fundamental particle-type) consciousness? This is generally regarded as the most serious problem facing contemporary panpsychism. I propose that mental combination can be construed as kind causal process culminating in a fusion, and show how this avoids the main difficulties with accounting for mental combination. (shrink)

Several variants of Lewis's Best System Account of Lawhood have been proposed that avoid its commitment to perfectly natural properties. There has been little discussion of the relative merits of these proposals, and little discussion of how one might extend this strategy to provide natural property-free variants of Lewis's other accounts, such as his accounts of duplication, intrinsicality, causation, counterfactuals, and reference. We undertake these projects in this paper. We begin by providing a framework for classifying and assessing the variants (...) of the Best System Account. We then evaluate these proposals, and identify the most promising candidates. We go on to develop a proposal for systematically modifying Lewis's other accounts so that they, too, avoid commitment to perfectly natural properties. We conclude by briefly considering a different route one might take to developing natural property-free versions of Lewis's other accounts, drawing on recent work by Williams. (shrink)

The meta-problem of consciousness is the problem of explaining why we have the intuition that there is a hard problem of consciousness. David Chalmers briefly notes that my phenomenal powers view may be able to answer to this challenge in a way that avoids problems (having to do with avoiding coincidence) facing other realist views. In this response, I will briefly outline the phenomenal powers view and my main arguments for it and—drawing in part on a similar view developed by (...) Harold Langsam—discuss how more precisely its answer to the challenge would go. (shrink)

A new layer of complexity, constituted of networks of information token recurrence, has been identified in socio-technical systems such as the Wikipedia online community and the Zooniverse citizen science platform. The identification of this complexity reveals that our current understanding of the actual structure of those systems, and consequently the structure of the entire World Wide Web, is incomplete, which raises novel questions for data science research but also from the perspective of social epistemology. Here we establish the principled foundations (...) and practical advantages of analyzing information diffusion within and across Web systems with Transcendental Information Cascades, and outline resulting directions for future study in the area of socio-technical systems. We also suggest that Transcendental Information Cascades may be applicable to any kind of time-evolving system that can be observed using digital technologies, and that the structures found in such systems comprise properties common to all naturally occurring complex systems.

I defend the following version of the ought-implies-can principle: (OIC) by virtue of conceptual necessity, an agent at a given time has an (objective, pro tanto) obligation to do only what the agent at that time has the ability and opportunity to do. In short, obligations correspond to ability plus opportunity. My argument has three premises: (1) obligations correspond to reasons for action; (2) reasons for action correspond to potential actions; (3) potential actions correspond to ability plus opportunity. In the (...) bulk of the paper I address six objections to OIC: three objections based on putative counterexamples, and three objections based on arguments to the effect that OIC conflicts with the is/ought thesis, the possibility of hard determinism, and the denial of the Principle of Alternate Possibilities.

This article compares James M. Buchanan's and John Rawls's theories of democratic governance. In particular it compares their positions on the characteristics of a legitimate social contract. Where Buchanan argues that additional police force can be used to quell political demonstrations, Rawls argues for a social contract that meets the difference principle.

Retributivists are often thought to give 'deontological' theories of punishment, arguing that we should punish not for the beneficial consequences of doing so such as deterrence or incapacitation, but purely because justice demands it. Kant is often regarded as the paradigmatic retributivist. In some passages Kant does appear to give a deontological theory of punishment. For example, Kant insists that on an island where all the people were to leave the next day, forever dissolving and dispersing the community, the last (...) murderer in jail would have to have his execution carried out before the diaspora--justice demands it. In other passages, however, Kant defends punishment by appealing to its beneficial consequences. For example, after supposing that one man on a life raft pushes the other off to save his own life, Kant says that the former man should not be legally punished "because that punishment would have to be death, and it would be an absurd law that threatened death to one who refuses to die voluntarily in a dangerous situation." In this passage Kant's reasoning is that state laws, by threatening us with sanctions, are intended to prevent us from violating rights--the point of these laws is to deter. A law that imposes a punishment that could not deter is an absurd law. I argue that while Kant rejects consequentialism in thinking about moral actions, he distinguishes law and morality, and in the sphere of law, an action we take is to be justified by appealing to the good it yields. The point of legal punishment is to deter violations of rights and protect us from a state of nature in which no one's freedom is assured. Kant's theory of legal (as opposed to moral) punishment is not deontological. Nevertheless we can characterize his consequentialist theory of legal punishment as retributive in some sense. The paper then considers how the passages about punishment in which Kant invokes consequentialist thinking can be reconciled with other passages where he insists on punishment regardless of the consequences.

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

According to a naïve view sometimes apparent in the writings of moral philosophers, ‘ought’ often expresses a relation between agents and actions – the relation that obtains between an agent and an action when that action is what that agent ought to do. It is not part of this naïve view that ‘ought’ always expresses this relation – on the contrary, adherents of the naïve view are happy to allow that ‘ought’ also has an epistemic sense, on which it means, (...) roughly, that some proposition is likely to be the case, and adherents of the naïve view are also typically happy to allow that ‘ought’ also has an evaluative sense, on which it means, roughly, that were things ideal, some proposition would be the case.1 What is important to the naïve view is not that these other senses of ‘ought’ do not exist, but rather that they are not exhaustive – for what they leave out, is the important deliberative sense of ‘ought’, which is the central subject of moral inquiry about what we ought to do and why – and it is this deliberative sense of ‘ought’ which the naïve view understands to express a relation between agents and actions.2 In contrast, logically and linguistically sophisticated philosophers – with a few notable exceptions3 – have rejected this naïve view. According to a dominant perspective in the interpretation of deontic logic and in linguistic semantics, for example, articulated by Roderick Chisholm (1964) and Bernard Williams (1981) in philosophy and in the dominant paradigm in linguistic semantics as articulated in particular by..

You may not know me well enough to evaluate me in terms of my moral character, but I take it you believe I can be evaluated: it sounds strange to say that I am indeterminate, neither good nor bad nor intermediate. Yet I argue that the claim that most people are indeterminate is the conclusion of a sound argument—the indeterminacy paradox—with two premises: (1) most people are fragmented (they would behave deplorably in many and admirably in many other situations); (2) (...) fragmentation entails indeterminacy. I support (1) by examining psychological experiments in which most participants behave deplorably (e.g., by maltreating “prisoners” in a simulated prison) or admirably (e.g., by intervening in a simulated theft). I support (2) by arguing that, according to certain plausible conceptions, character evaluations presuppose behavioral consistency (lack of fragmentation). Possible reactions to the paradox include: (a) denying that the experiments are relevant to character; (b) upholding conceptions according to which character evaluations do not presuppose consistency; (c) granting that most people are indeterminate and explaining why it appears otherwise. I defend (c) against (a) and (b). (shrink)

The paper points out that the modern formulation of Bohm’s quantum theory known as Bohmian mechanics is committed only to particles’ positions and a law of motion. We explain how this view can avoid the open questions that the traditional view faces according to which Bohm’s theory is committed to a wave-function that is a physical entity over and above the particles, although it is defined on configuration space instead of three-dimensional space. We then enquire into the status of the (...) law of motion, elaborating on how the main philosophical options to ground a law of motion, namely Humeanism and dispositionalism, can be applied to Bohmian mechanics. In conclusion, we sketch out how these options apply to primitive ontology approaches to quantum mechanics in general. (shrink)

Imperatives cannot be true or false, so they are shunned by logicians. And yet imperatives can be combined by logical connectives: "kiss me and hug me" is the conjunction of "kiss me" with "hug me". This example may suggest that declarative and imperative logic are isomorphic: just as the conjunction of two declaratives is true exactly if both conjuncts are true, the conjunction of two imperatives is satisfied exactly if both conjuncts are satisfied—what more is there to say? Much more, (...) I argue. "If you love me, kiss me", a conditional imperative, mixes a declarative antecedent ("you love me") with an imperative consequent ("kiss me"); it is satisfied if you love and kiss me, violated if you love but don't kiss me, and avoided if you don't love me. So we need a logic of three -valued imperatives which mixes declaratives with imperatives. I develop such a logic. (shrink)

Le XI.ème Congrès International de Philosophie Médiévale de la Société Internationale pour l’Étude de la Philosophie Médiévale (S.I.E.P.M..) s’est déroulé à Porto (Portugal), du 26 au 30 août 2002, sous le thème général: Intellect et Imagination dans la Philosophie Médiévale. A partir des héritages platonicien, aristotélicien, stoïcien, ou néo-platonicien (dans leurs variantes grecques, latines, arabes, juives), la conceptualisation et la problématisation de l’imagination et de l’intellect, ou même des facultés de l’âme en général, apparaissaient comme une ouverture possible pour aborder (...) les principaux points de la pensée médiévale. Les Actes du congrès montrent que « imagination » et « intellect » sont porteurs d’une richesse philosophique extraordinaire dans l’économie de la philosophie médiévale et de la constitution de ses spécificités historiques. Dans sa signification la plus large, la théorisation de ces deux facultés de l’âme permet de dédoubler le débat en au moins six grands domaines: — la relation avec le sensible, où la fantaisie/l’imagination joue le rôle de médiation dans la perception du monde et dans la constitution de la connaissance ; — la réflexion sur l’acte de connaître et la découverte de soi en tant que sujet de pensée ; — la position dans la nature, dans le cosmos, et dans le temps de celui qui pense et qui connaît par les sens externes, internes et par l’intellect ; — la recherche d’un fondement pour la connaissance et l’action, par la possibilité du dépassement de la distante proximité du transcendant, de l’absolu, de la vérité et du bien ; — la réalisation de la félicité en tant qu’objectif ultime, de même que la découverte d’une tendance au dépassement actif ou mystique de toutes les limites naturelles et des facultés de l’âme ; — la constitution de théories de l’image, sensible ou intellectuelle, et de ses fonctions. Les 3 volumes d’Actes incluent les 16 leçons plénières et 112 communications, ainsi que les index correspondants (manuscrits ; noms anciens et médiévaux ; noms modernes ; auteurs). Le volume IV des Actes, contenant 39 communications et des index, est publié par la revue " Mediaevalia. Textos e Estudos ", du Gabinete de Filosofia Medieval de l’Universidade do Porto (volume 23, de 2004).

Why does classical equilibrium statistical mechanics work? Malament and Zabell (1980) noticed that, for ergodic dynamical systems, the unique absolutely continuous invariant probability measure is the microcanonical. Earman and Rédei (1996) replied that systems of interest are very probably not ergodic, so that absolutely continuous invariant probability measures very distant from the microcanonical exist. In response I define the generalized properties of epsilon-ergodicity and epsilon-continuity, I review computational evidence indicating that systems of interest are epsilon-ergodic, I adapt Malament and Zabell’s (...) defense of absolute continuity to support epsilon-continuity, and I prove that, for epsilon-ergodic systems, every epsilon-continuous invariant probability measure is very close to the microcanonical.

Over the past fifteen years there has been a considerable amount of debate concerning what theoretical population dynamic models tell us about the nature of natural selection and drift. On the causal interpretation, these models describe the causes of population change. On the statistical interpretation, the models of population dynamics models specify statistical parameters that explain, predict, and quantify changes in population structure, without identifying the causes of those changes. Selection and drift are part of a statistical description of population (...) change; they are not discrete, apportionable causes. Our objective here is to provide a definitive statement of the statistical position, so as to allay some confusions in the current literature. We outline four commitments that are central to statisticalism. They are: 1. Natural Selection is a higher order effect; 2. Trait fitness is primitive; 3. Modern Synthesis (MS)-models are substrate neutral; 4. MS-selection and drift are model-relative. (shrink)

Imperatives cannot be true, but they can be obeyed or binding: `Surrender!' is obeyed if you surrender and is binding if you have a reason to surrender. A pure declarative argument — whose premisses and conclusion are declaratives — is valid exactly if, necessarily, its conclusion is true if the conjunction of its premisses is true; similarly, I suggest, a pure imperative argument — whose premisses and conclusion are imperatives — is obedience-valid (alternatively: bindingness-valid) exactly if, necessarily, its conclusion is (...) obeyed (alternatively: binding) if the conjunction of its premisses is. I argue that there are two kinds of bindingness, and that a vacillation between two corresponding variants of bindingness-validity largely explains conflicting intuitions concerning the validity of some pure imperative arguments. I prove that for each of those two variants of bindingness-validity there is an equivalent variant of obedience-validity. Finally, I address alternative accounts of pure imperative inference.

Looking at the recent spate of claims about “fake news” which appear to be a new feature of political discourse, I argue that fake news presents an interesting problem in epistemology. Te phenomena of fake news trades upon tolerating a certain indiference towards truth, which is sometimes expressed insincerely by political actors. Tis indiference and insincerity, I argue, has been allowed to fourish due to the way in which we have set the terms of the “public” epistemology that maintains what (...) is considered “rational” public discourse. I argue one potential salve to the problem of fake news is to challenge this public epistemology by injecting a certain ethical consideration back into the discourse. (shrink)

The Integrated Information Theory of consciousness (IIT) claims that consciousness is identical to maximal integrated information, or maximal Φ. One objection to IIT is based on what may be called the intrinsicality problem: consciousness is an intrinsic property, but maximal Φ is an extrinsic property; therefore, they cannot be identical. In this paper, I show that this problem is not unique to IIT, but rather derives from a trilemma that confronts almost any theory of consciousness. Given most theories of consciousness, (...) the following three claims are inconsistent. INTRINSICALITY: Consciousness is intrinsic. NON-OVERLAP: Conscious systems do not overlap with other conscious systems (a la Unger’s problem of the many). REDUCTIONISM: Consciousness is constituted by more fundamental properties (as per standard versions of physicalism and Russellian monism). In view of this, I will consider whether rejecting INTRINSICALITY is necessarily less plausible than rejecting NON-OVERLAP or REDUCTIONISM. I will also consider whether IIT is necessarily committed to rejecting INTRINSICALITY or whether it could also accept solutions that reject NON-OVERLAP or REDUCTIONISM instead. I will suggest that the best option for IIT may be a solution that rejects REDUCTIONISM rather than INTRINSICALITY or NON-OVERLAP. (shrink)
