Jc Beall has made several contributions to the theory of restricted quantification in relevant logics. This paper examines these contributions and proposes an alternative account of restricted universals. The alternative is not, however, a theory of relevant restricted universals in any real sense. It is, however, a theory of restricted universals phrased in the most plausible general quantificational theory for relevant logics—Kit Fine’s stratified semantics. The motivation both for choosing this semantic framework and for choosing the particular theory of restricted (...) quantification we use is because they are the best way of dealing with these topics from Beall’s theory-building theory picture of logic, establishing a second point of contact with Beall’s work.

Challenging the basic assumptions of a meat-eating society, Deep Vegetarianism is a spirited and compelling defense of a vegetarian lifestyle. Considering all of the major arguments both for and against vegetarianism and the habits of meat-eaters, vegetarians, and vegans alike, Michael Allen Fox addresses vegetarianism's cultural, historical, and philosophical background; details vegetarianism's impact on one's living and thinking; and relates vegetarianism to classical and recent defenses of the moral status of animals. Demonstrating how a vegetarian diet is related (...) to our awareness of the world and our ethical outlook on life, Fox looks at the different kinds of vegetarian commitments people make and their reasons for making them. In chapters that address such issues as the experiences, emotions, and grounds that are part of choosing vegetarianism, Fox discusses not only good health, animal suffering, and the environmental impacts of meat production, but such issues as the meaning of food, world hunger, religion and spirituality, and, significantly, the links share between vegetarianism and other human rights movements and ideologies, particularly feminism. In an extensive chapter that addresses arguments made by advocates of meat-eating, Fox speaks to claims of humans as natural carnivores, animals as replaceable, and vegetarians as anti-feminist. He also addresses arguments surrounding the eating habits of indigenous peoples, eating free-range animals, and carnivorous behavior among animals. The most complete examination of the vegetarian outlook to date, Deep Vegetarianism reveals the broad range of philosophical views that contribute to such a choice. It recognizes, and calls for, a conscious awareness of -- and an individual responsibility to -- the issues that exist in the moral, political, and social spheres of our existence. With its lively and controversial discussion, Deep Vegetarianism promises to appeal to anyone looking to explore the relationship between dietary choice, lifestyle, the treatment of animals and the environment, and personal ethical responsibility. It will also be particularly useful for students and teachers of moral philosophy, ethics, religion, comparative cultures, ecology, and feminism. (shrink)

We consider an extended notion of reinforcement learning in which the environment can simulate the agent and base its outputs on the agent's hypothetical behavior. Since good performance usually requires paying attention to whatever things the environment's outputs are based on, we argue that for an agent to achieve on-average good performance across many such extended environments, it is necessary for the agent to self-reflect. Thus weighted-average performance over the space of all suitably well-behaved extended environments could be considered a (...) way of measuring how self-reflective an agent is. We give examples of extended environments and introduce a simple transformation which experimentally seems to increase some standard RL agents' performance in a certain type of extended environment.

I propose a framework, derived from moral theory, for assessing the moral status of intelligent machines. Using this framework, I claim that some current and foreseeable intelligent machines have approximately as much moral status as plants, trees, and other environmental entities. This claim raises the question: what obligations could a moral agent (e.g., a normal adult human) have toward an intelligent machine? I propose that the threshold for any moral obligation should be the "functional morality" of Wallach and Allen (...) [20], while the upper limit of our obligations should not exceed the upper limit of our obligations toward plants, trees, and other environmental entities. (shrink)

Amerika und die Welt befinden sich im Prozess des Zusammenbruchs durch übermäßiges Bevölkerungswachstum, das meiste davon im letzten Jahrhundert und jetzt alles aufgrund der Menschen in der 3. Welt. Der Verbrauch von Ressourcen und die Hinzufügung von ein oder zwei Milliarden weiteren etwa 2100 wird die industrielle Zivilisation zusammenbrechen und Hunger, Krankheit, Gewalt und Krieg in einem erschütternden Ausmaß herbeiführen. Milliarden werden sterben, und ein Atomkrieg ist so gut wie sicher. In Amerika wird dies durch massive Einwanderung und Reproduktion von (...) Einwanderern enorm beschleunigt, verbunden mit Missbräuchen, die durch die Demokratie ermöglicht werden. Die verdorbene menschliche Natur verwandelt den Traum von Demokratie und Vielfalt unaufhaltsam in einen Alptraum von Verbrechen und Armut. Die Hauptursache des Zusammenbruchs ist die Unfähigkeit unserer angeborenen Psychologie, sich an die moderne Welt anzupassen, was dazu führt, dass Menschen nicht verwandte Personen behandeln, als hätten sie gemeinsame Interessen. Dies, plus Unwissenheit über grundlegende Biologie und Psychologie, führt zu den Social-Engineering-Wahnvorstellungen der teilweise Gebildeten, die demokratische Gesellschaften kontrollieren. Nur wenige verstehen, dass, wenn Sie einer Person helfen, jemand anderem zu schaden – es gibt kein kostenloses Mittagessen und jeder einzelne Gegenstand, den jemand konsumiert, zerstört die Erde unwiederbringlich. Folglich ist die Sozialpolitik überall unhaltbar, und eine nach der anderen werden alle Gesellschaften ohne strenge Kontrolle des Egoismus in Anarchie oder Diktatur zusammenbrechen. Ohne dramatische und sofortige Veränderungen gibt es keine Hoffnung, den Zusammenbruch Amerikas oder eines Landes, das einem demokratischen System folgt, zu verhindern. Daher mein Essay "Suicide by Democracy". Es ist jetzt auch klar, dass die sieben Soziopathen, die China regieren, den 3. Weltkrieg gewinnen, und so mein abschließender Essay über sie. Die einzige größere Bedrohung ist Künstliche Intelligenz, auf die ich kurz eingehe. Der Schlüssel zu allem, was uns betrifft, ist die Biologie, und sie ist die Vergessenheit, die Millionen kluger gebildeter Menschen wie Obama, Chomsky,Clinton, die Demokratische Partei und den Papst dazu bringt, selbstmörderische utopische Ideale zu vertreten, die unaufhaltsam direkt in die Hölle auf Erden führen. Wie W bemerkte, ist es das, was immer vor unseren Augen ist, das am schwersten zu sehen ist. Wir leben in der Welt des bewussten deliberativen linguistischen Systems 2, aber es ist unbewusstes, automatisches reflexives System 1, das regiert. Dies ist die Quelle der universellen Blindheit, die von Searles The Phenomenological Illusion (TPI), Pinker es Blank Slate und Tooby and Cosmides' Standard Social Science Model beschrieben wird. Die erste Gruppe von Artikeln versucht, einen Einblick in unser Verhalten zu geben, das einigermaßen frei von theoretischen Wahnvorstellungen ist. In den nächsten drei Gruppen beeinetiere ich drei der wichtigsten Wahnvorstellungen, die eine nachhaltige Welt verhindern – Technologie, Religion und Politik (genossenschaftliche Gruppen). Die Leute glauben, dass die Gesellschaft durch sie gerettet werden kann, also gebe ich einige Vorschläge im Rest des Buches, warum dies unwahrscheinlich ist, durch kurze Artikel und Rezensionen von aktuellen Büchern von bekannten Schriftstellern. Ein anderer Abschnitt beschreibt den religiösen Wahn – dass es eine Supermacht gibt, die uns retten wird. Der nächste Abschnitt beschreibt die digitalen Wahnvorstellungen, die die Sprachspiele von System 2 mit den Automatismen von System eins verwechseln und daher biologische Maschinen (d. h. Menschen) nicht von anderen Maschinentypen (d. h. Computern) unterscheiden können. Andere digitale Wahnvorstellungen sind, dass wir vor dem reinen Bösen (Selbstsucht) von System 1 durch Computer/AI/Robotik/Nanotechnologie/Gentechnik, die von System 2 geschaffen wurden, gerettet werden. Der No Free Lunch-Prinzipal sagt uns, dass es ernste und möglicherweise tödliche Folgen geben wird. Der letzte Abschnitt beschreibt the One Big Happy Family Delusion, d.h., dass wir für die Zusammenarbeit mit allen ausgewählt werden und dass die euphonious Ideale von Demokratie, Vielfalt und Gleichheit uns in die Utopie führen werden, wenn wir die Dinge einfach richtig handhaben (die Möglichkeit der Politik). Auch hier sollte uns das Prinzip "Kein freies Mittagessen" warnen, dass es nicht wahr sein kann, und wir sehen in der geschichteten und ganzen heutigen Welt, dass ohne strenge Kontrollen Egoismus und Dummheit die Oberhand gewinnen und bald jede Nation zerstören, die diese Wahnvorstellungenumarmt. Darüber hinaus reduziert der Affengeist die Zukunft steil, und so arbeiten wir beim Verkauf des Erbes unseres Nachkommen für temporären Komfort zusammen, was die Probleme erheblich verschärft.

Allen Buchanan and Russel Powell’s The Evolution of Moral Progress (EMP) is likely to become a landmark. It adeptly builds on much of the recent empirical work, weaving it together with philosophical material drawn from a series of essays published by the two authors. EMP makes the case that moral progress is not only consistent with human psychology but—under some conditions—likely. At its heart is a careful, well-developed rebuttal to the idea that there are evolved constraints endogenous to human (...) minds that place significant limits on various forms of moral progress, especially on the spread and sustainability of inclusive values. The alternative picture they present acknowledges that evolutionary history has shaped how our minds produce behaviour, but emphasizes that the contexts in which they currently operate are just as pivotal. While safe and stable ecological and social circumstances are hospitable to cosmopolitanism and encouraging of inclusive values, dangerous and threatening circumstances are more favourable to parochialism, exclusivist values, and morally regressive outgroup hostility (also see Buchanan and Powell [2015], [2016], [2017]). Overall, EMP is a compelling, well-researched, and timely book. It articulates arguably the most persuasive naturalistic theory of moral progress to date, and lays the groundwork for important and impactful research. (shrink)

In this paper I explain and defend the content and justification of John Rawls's conception of human rights, as he outlines it in his major work: The Law of Peoples. I focus, in particular, on the criticisms of Allen Buchanan. Buchanan distinguishes four lines of argument that Rawls uses to derive what, according to Buchanan, is a 'lean' list of human rights : the Political Conception Argument, the Associationist Argument, the Cooperation Argument, and finally the Functionalist Argument. In each (...) case Buchanan proceeds to show how the premises of Rawls's argument lead to absurd consequences if taken to their logical conclusion. It can be shown, however, that the reason these consequences follow is that Buchanan misunderstands and misrepresents Rawls's premises. (shrink)

Must we choose between reducing material substances to collections of properties, a’ la Berkeley and Hume or positing bare particulars, in the manner of Locke? Having repudiated the notion that a substance could simply be a collection of properties existing on their own, is there a viable alternative to the Lockean notion of a substratum, a being essentially devoid of character? E.J. Lowe and Michael Loux would answer here in the affirmative. Both recommend hylomorphism as an upgrade on the (...) metaphysics of the British empiricists: treating a material substance as its essential 'form,' this embodied 'substance' universal being, in turn, the substratum in which its 'accidents' inhere. Here, I evaluate this Aristotelian metaphysics, identifying the advantages it enjoys over the empiricist's alternatives pertaining to dependence, unity, identity, change, and the distinction between essential and accidental properties. I also develop solutions to the two problems that Loux sees it posing. (shrink)

Review of Hegel, Literature and the Problem of Agency by Allen Speight.

The representationist maintains that an experience represents a state of affairs. To elaborate, a stimulus of one’s sensorium produces, according to her, a “phenomenal composite” made up of “phenomenal properties” that are the typical effects of certain mind-independent features of the world, which are thereby represented. It is such features, via their phenomenal representatives, of which the subject of an experience would become aware were she to engage in introspection. So, one might ask, what state of affairs would be represented (...) by an illusory experience, that is, one to which no state of affairs in the vicinity of its subject corresponds? The answer, according to the standard defense of representationism (SD), is the same state of affairs that would obtain in its subject’s surroundings if it were veridical. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 134-135 [Access article in PDF] Allen Speight. Hegel, Literature and the Problem of Agency. New York: Cambridge University Press, 2001. Pp. xii + 154. Cloth, $54.95. Paper, $18.95. Hegel's notorious use of literary references in his Phenomenology of Spirit has been a source of numerous interpretive difficulties, sparking disagreements not only about the actual referents of Hegel's literary allusions, but (...) also—and more importantly—about the meaning and purpose of such allusions. In this insightful, highly readable new book, Allen Speight challenges the stale orthodoxies that have pitted the Phenomenology's systematic/philosophical readers against its literary/historical ones, and offers an innovative interpretation that takes seriously the work's literary structure and allusions, while also giving due consideration to its systematic philosophical aims. Combining the rich sensibility of a literary mind with the careful rigor of a philosophical mind, Speight deftly shows how Hegel's Phenomenology is a work whose very aim, in part, is to transcend the traditional, but often limiting, dichotomy between philosophy and literature.As Speight explains it, the general purpose of this book is to make "a contribution to understanding the philosophical project of the Phenomenology and why that project requires Hegel's appropriation of literary works and forms as it does" (9-10). The book's philosophical point of departure is the critical mass of recent scholarship that sees Hegel's epistemological task in the Phenomenology as essentially Sellarsian in its critique of the "Myth of the Given." For Speight, the Hegelian critique of the myth of the given implies that all knowledge claims are essentially corrigible and socially mediated, and this implies—in turn—that any attempt to draw rigid lines of demarcation between a purely "systematic" and a purely "historical" or "anthropological" approach to philosophy and its problems must ultimately fail. From this interpretive vantage point, Speight holds, a strong case can be made for the essentially literary character of Hegel's Phenomenology, and the essentially philosophical purpose of his literary allusions. As Speight is careful to acknowledge, his own distinctive approach to the Phenomenology is not meant to rule out other, divergent emphases or interpretations, but only to provide "a way of better understanding the role that literature plays within the philosophical enterprise of the work as a whole" (18).Speight begins to deliver the details of his promised "better way" by investigating what he calls the "literary turn" or the seemingly sudden "eruption of the literary" that starts to motivate the Phenomenology's transition from the section on "Reason" to the section on "Spirit." For Speight, the shapes of Active Reason that are crucial in this transition begin to raise a new set of problems concerning human agency. Furthermore, it is not at all a coincidence that Hegel's heightened concern with agency at this juncture of the Phenomenology [End Page 134] is accompanied by an unmistakable burst of literary references. Rather, it is an indicator of Hegel's careful, deliberate, and self-conscious strategy of using literature to make a philosophical point about agency, since it is literature—according to Speight's Hegel—that gives us privileged access to the philosophical problems of agency and their potential resolution.For Speight, Hegel's use of tragedy gives us special insight into the retrospectivity of all human action; his use of comedy points to the theatricality (or what we might call the socially mediated expressivity) of all human action; and his use of the romantic novel points to the necessity (and eventually opens up the possibility) of the forgiveness implied by all human action. While Hegel had already made use of both tragedy and comedy in the Reason section of the Phenomenology, it is only in the Spirit section, Speight argues, that these literary-philosophical shapes are taken up (e.g., in Antigone and Rameau's Nephew) in a historically self-conscious way that can lead (via the "beautiful soul" novel) to the possibility of forgiveness and thereby instigate the transition to the Religion section.Speight's "better way...

Obwohl dieser Band ein wenig datiert ist, gibt es nur wenige aktuelle populäre Bücher, die sich speziell mit der Psychologie des Mordes beschäftigen und es ist ein schneller Überblick für ein paar Dollar, also noch wert die Mühe. Es macht keinen Versuch, umfassend zu sein und ist stellenweise etwas oberflächlich, wobei der Leser erwartet, die Lücken aus seinen vielen anderen Büchern und der umfangreichen Literatur über Gewalt zu füllen. Für ein Update siehe z.B. Buss, The Handbook of Evolutionary Psychology 2nd (...) ed. V1 (2016) S. 265, 266, 270–282, 388–389, 545–546, 547, 566 und Buss, Evolutionary Psychology 5th ed. (2015) P 26, 96–97,223, 293-4, 300, 309–312, 410 und Shackelford and Hansen, The Evolution of Violence (2014). Er gehört seit mehreren Jahrzehnten zu den beste Evolutions psychologen und deckt in seinen Arbeiten ein breites Spektrum an Verhaltensweisen ab, aber hier konzentriert er sich fast ausschließlich auf die psychologischen Mechanismen, die einzelne Menschen zum Mord führen, und ihre mögliche evolutionäre Funktion im EWR (Environment of Evolutionary Adaptation – d.h. die Ebenen Afrikas in den letzten Millionen Jahren oder so). -/- Buss beginnt mit der Erkenntnis, dass wie bei anderen Verhaltensweisen "alternative" Erklärungen wie Psychopathologie, Eifersucht, soziales Umfeld, Gruppendruck, Drogen und Alkohol usw. nicht wirklich erklären, da die Frage nach wie vor bleibt, warum diese mörderische Impulse erzeugen, d.h. sie sind die nahen Ursachen und nicht die ultimativen evolutionären (genetischen) Ursachen. Wie immer läuft es unweigerlich auf inklusive Fitness (genetische Fitness von Verwandten) und damit auf den Kampf um den Zugang zu Kumpels und Ressourcen hinaus, der die ultimative Erklärung für das gesamte Verhalten in allen Organismen ist. Soziologische Daten (und der gesunde Menschenverstand) machen deutlich, dass jüngere ärmere Männchen am ehesten töten. Er präsentiert seine eigenen und andere Morddaten aus Industrienationen und Stammeskulturen, konspeziertes Töten von Tieren, Archäologie, FBI-Daten und seine eigene Forschung über die Mordfantasien normaler Menschen. Viele archäologische Beweise häufen sich weiterhin von Morden, einschließlich der von ganzen Gruppen oder von Gruppen abzüglich junger Frauen, in prähistorischen Zeiten. -/- Nachdem ich Buss' Kommentare untersucht habe, präsentiere ich eine sehr kurze Zusammenfassung der absichtlichen Psychologie (die logische Struktur der Rationalität), die in meinen vielen anderen Artikeln und Büchern ausführlich behandelt wird. -/- Diejenigen, die viel Zeit haben, die eine detaillierte Geschichte mörderischer Gewalt aus evolutionärer Perspektive wollen, können Steven Pinkers "The Better Angels of Our Nature Why Violence Has Declined" (2012) und meineRezension, leicht im Netz und in zwei meiner jüngsten Bücher lesen. Kurz, Pinker stellt fest, dass Mord hat stetig und dramatisch um den Faktor etwa 30 seit unseren Tagen als Forager gesunken. Obwohl Waffen es jetzt für jeden extrem einfach machen, zu töten, ist Tötung viel seltener. Pinker glaubt, dass dies auf verschiedene soziale Mechanismen zurückzuführen ist, die unsere "besseren Engel" hervorbringen, aber ich denke, es ist hauptsächlich auf die vorübergehende Fülle von Ressourcen durch die gnadenlose Vergewaltigung unseres Planeten zurückzuführen, gepaart mit erhöhter Polizeipräsenz, mit Kommunikations- und Überwachungs- und Rechtssystemen, die es viel wahrscheinlicher machen, bestraft zu werden. Dies wird jedes Mal deutlich, wenn es sogar eine kurze und lokale Abwesenheit der Polizei gibt. -/- Wer aus der modernen zweisystems-Sichteinen umfassenden, aktuellen Rahmen für menschliches Verhalten wünscht, kann mein Buch "The Logical Structure of Philosophy, Psychology, Mindand Language in Ludwig Wittgenstein and John Searle' 2nd ed (2019) konsultieren.

Some types of solar radiation management (SRM) research are ethically problematic because they expose persons, animals, and ecosystems to significant risks. In our earlier work, we argued for ethical norms for SRM research based on norms for biomedical research. Biomedical researchers may not conduct research on persons without their consent, but universal consent is impractical for SRM research. We argue that instead of requiring universal consent, ethical norms for SRM research require only political legitimacy in decision-making about global SRM trials. (...) Using Allen Buchanan & Robert Keohane's model of global political legitimacy, we examine several existing global institutions as possible analogues for a politically legitimate SRM decision-making body.

This a review of Logic Primer, written by Colin Allen and Michael Hand and published by MIT Press in 1992.

This book launches a sustained defense of a radical interpretation of the doctrine of the open future. Patrick Todd argues that all claims about undetermined aspects of the future are simply false.

At least since Aristotle’s famous 'sea-battle' passages in On Interpretation 9, some substantial minority of philosophers has been attracted to the doctrine of the open future--the doctrine that future contingent statements are not true. But, prima facie, such views seem inconsistent with the following intuition: if something has happened, then (looking back) it was the case that it would happen. How can it be that, looking forwards, it isn’t true that there will be a sea battle, while also being true (...) that, looking backwards, it was the case that there would be a sea battle? This tension forms, in large part, what might be called the problem of future contingents. A dominant trend in temporal logic and semantic theorizing about future contingents seeks to validate both intuitions. Theorists in this tradition--including some interpretations of Aristotle, but paradigmatically, Thomason (1970), as well as more recent developments in Belnap, et. al (2001) and MacFarlane (2003, 2014)--have argued that the apparent tension between the intuitions is in fact merely apparent. In short, such theorists seek to maintain both of the following two theses: (i) the open future: Future contingents are not true, and (ii) retro-closure: From the fact that something is true, it follows that it was the case that it would be true. It is well-known that reflection on the problem of future contingents has in many ways been inspired by importantly parallel issues regarding divine foreknowledge and indeterminism. In this paper, we take up this perspective, and ask what accepting both the open future and retro-closure predicts about omniscience. When we theorize about a perfect knower, we are theorizing about what an ideal agent ought to believe. Our contention is that there isn’t an acceptable view of ideally rational belief given the assumptions of the open future and retro-closure, and thus this casts doubt on the conjunction of those assumptions.

I want to suggest that it would be bad if compatibilism were true, and that this gives us good reason to think that it isn't. This is, you might think, an outlandish argument, and the considerable burden of this paper is to convince you otherwise. There are two key elements at stake in this argument. The first is that it would be ‐ in a distinctive sense to be explained ‐ bad if compatibilism were true. The thought here is that (...) compatibilism ultimately presents us with a picture on which, in principle, powerful manipulators can effectively guarantee that finite moral agents should become blameworthy. To my mind, this isn't just false ‐ though I think that it is ‐ it is also such that it would be bad (unfortunate, undesirable…) if it were true. The second is that the fact that it would be ‐ in this sense ‐ bad if true gives us reason to think that it isn't. It may be bad that there is no afterlife. But that, in itself, hardly gives us reason to think that there is an afterlife. That is true, but ‐ as others before me have suggested ‐ when the object of the relevant badness is morality itself, the inference seems secure. A more general aim of the paper is to investigate the nature of this very form of argument in itself, and I compare my argument (inter alia) to a recent argument from Sayre–McCord against the possibility of genuine moral dilemmas.

It is widely accepted that there is what has been called a non-hypocrisy norm on the appropriateness of moral blame; roughly, one has standing to blame only if one is not guilty of the very offence one seeks to criticize. Our acceptance of this norm is embodied in the common retort to criticism, “Who are you to blame me?”. But there is a paradox lurking behind this commonplace norm. If it is always inappropriate for x to blame y for a (...) wrong that x has committed, then all cases in which x blames x (i.e. cases of self-blame) are rendered inappropriate. But it seems to be ethical common-sense that we are often, sadly, in position (indeed, excellent, privileged position) to blame ourselves for our own moral failings. And thus we have a paradox: a conflict between the inappropriateness of hypocritical blame, and the appropriateness of self-blame. We consider several ways of resolving the paradox, and contend none is as defensible as a position that simply accepts it: we should never blame ourselves. In defending this startling position, we defend a crucial distinction between self-blame and guilt. (shrink)

Incompatibilism about responsibility and determinism is sometimes directly construed as the thesis that if we found out that determinism is true, we would have to give up the reactive attitudes. Call this "the consequence". I argue that this is a mistake: the strict modal thesis does not entail the consequence. First, some incompatibilists (who are also libertarians) may be what we might call *resolute responsibility theorists* (or "flip-floppers"). On this view, if we found out that determinism is true, this would (...) not be to find out that no one is responsible; instead, what this would suggest is that incompatibilism is after all false. Second, some incompatibilists may instead deny the claim that if we found out that no one deserves the reactiveattitudes, we would have to give up the reactive attitudes. Call this position *innocent incompatibilism*. I explore several different reasons why the fact that no one deserves the reactive attitudes likely does not translate into a requirement for us to give up the reactive attitudes. The upshot: incompatibilism may be practically irrelevant, even if true. (shrink)

Thomas Reid’s philosophy is a philosophy of mind—a Pneumatology in the idiom of 18th century Scotland. His overarching philosophical project is to construct an account of the nature and operations of the human mind, focusing on the two-way correspondence, in perception and action, between the thinking principle within and the material world without. Like his contemporaries, Reid’s treatment of these topics aimed to incorporate the lessons of the scientific revolution. What sets Reid’s philosophy of mind apart is his commitment to (...) a set of intuitive contingent truths he called the principles of common sense. This difference, as this chapter will show, enables Reid to construct an account of mind that resists the temptation to which so many philosophers in his day and ours succumb, i.e., the temptation, in his words, to materialize minds or spiritualize bodies.

Recently, philosophers have turned their attention to the question, not when a given agent is blameworthy for what she does, but when a further agent has the moral standing to blame her for what she does. Philosophers have proposed at least four conditions on having “moral standing”: -/- 1. One’s blame would not be “hypocritical”. 2. One is not oneself “involved in” the target agent’s wrongdoing. 3. One must be warranted in believing that the target is indeed blameworthy for the (...) wrongdoing. 4. The target’s wrongdoing must some of “one’s business”. -/- These conditions are often proposed as both conditions on one and the same thing, and as marking fundamentally different ways of “losing standing.” Here I call these claims into question. First, I claim that conditions (3) and (4) are simply conditions on different things than are conditions (1) and (2). Second, I argue that condition (2) reduces to condition (1): when “involvement” removes someone’s standing to blame, it does so only by indicating something further about that agent, viz., that he or she lacks commitment to the values that condemn the wrongdoer’s action. The result: after we clarify the nature of the non-hypocrisy condition, we will have a unified account of moral standing to blame. Issues also discussed: whether standing can ever be regained, the relationship between standing and our "moral fragility", the difference between mere inconsistency and hypocrisy, and whether a condition of standing might be derived from deeper facts about the "equality of persons".

This paper explores the idea that many “simple minded” invertebrates are “natural zombies” in that they utilize their senses in intelligent ways, but without phenomenal awareness. The discussion considers how “first-order” representationalist theories of consciousness meet the explanatory challenge posed by blindsight. It would be an advantage of first-order representationalism, over higher-order versions, if it does not rule out consciousness in most non-human animals. However, it is argued that a first-order representationalism which adequately accounts for blindsight also implies that most (...) non-mammals are not conscious. The example of the honey bee is used to illuminate these claims. Although there is some reason to think that bees have simple beliefs and desires, nevertheless, their visually-mediated cognizing is comparable to that of an animal with blindsight. There is also reason to think that the study of blindsight can also help determine how consciousness is distributed in the animal world. (shrink)

In this paper, we clarify, unpack, and ultimately resist what is perhaps the most prominent argument for the compatibility of free will and determinism: the epistemic argument for compatibilism. We focus on one such argument as articulated by David Lewis: (i) we know we are free, (ii) for all we know everything is predetermined, (iii) if we know we are free but for all we know everything is predetermined, then for all we know we are free but everything is predetermined, (...) (iv) if for all we know we are free but predetermined, then it is really possible that we are, so (v) compatibilism. We uncover how the crucial epistemic modality underlying (iv) must be understood, and contend that, understood this way, the libertarian can resist (iv). Importantly, however, resisting the argument does commit the libertarian to what has been called “flip-flopping”—but we argue that this is perfectly coherent. We conclude by articulating two crucially ways the libertarian can resist the argument, by saying that we can know that determinism is false "from the armchair". (shrink)

This essay (a revised version of my undergraduate honors thesis at Stanford) constructs a theory of analogy as it applies to argumentation and reasoning, especially as used in fields such as philosophy and law. The word analogy has been used in different senses, which the essay defines. The theory developed herein applies to analogia rationis, or analogical reasoning. Building on the framework of situation theory, a type of logical relation called determination is defined. This determination relation solves a puzzle about (...) analogy in the context of logical argument, namely, whether an analogous situation contributes anything logically over and above what could be inferred from the application of prior knowledge to a present situation. Scholars of reasoning have often claimed that analogical arguments are never logically valid, and that they therefore lack cogency. However, when the right type of determination structure exists, it is possible to prove that projecting a conclusion inferred by analogy onto the situation about which one is reasoning is both valid and non-redundant. Various other properties and consequences of the determination relation are also proven. Some analogical arguments are based on principles such as similarity, which are not logically valid. The theory therefore provides us with a way to distinguish between legitimate and illegitimate arguments. It also provides an alternative to procedures based on the assessment of similarity for constructing analogies in artificial intelligence systems. (shrink)

Epistemic akrasia arises when one holds a belief even though one judges it to be irrational or unjustified. While there is some debate about whether epistemic akrasia is possible, this paper will assume for the sake of argument that it is in order to consider whether it can be rational. The paper will show that it can. More precisely, cases can arise in which both the belief one judges to be irrational and one’s judgment of it are epistemically rational in (...) the sense that both are supported by sufficient evidence.

In the United States, prohibitionist policies are used as the primary approach to combat the negative effect of substance use on society. An extensive academic literature spanning the disciplines of economics, political science, and multiculturalism documents the great social costs of the United States’ “War on Drugs” both nationally and internationally. These costs come with at best marginal effect on substance abuse and other crimes linked to the drug trade. In many cases, there is a reason to believe that these (...) policies exacerbate the problems they aim to address. This article explores psychologists’ ethical commitments to social change concerning such drug policy, given the field of psychology’s expanding commitment to social justice. We examine arguments regarding the boundaries between psychologists’ personal and professional ethics with regard to political participation. Using drug prohibition as an exemplar, we suggest that many psychologists’ political actions and professional ethics may be misaligned. Ultimately, we conclude that the endorsement of prohibitionist drug policies is in direct conflict with the guiding ethical principles put forth by the American Psychological Association’s Ethical Principles of Psychologists and Code of Conduct.

Background: Transgender health care is a subject of much debate among clinicians, political commentators, and policy-makers. While the World Professional Association of Transgender Health (WPATH) Standards of Care (SOC) establish clinical standards, these standards contain implied ethics but lack explicit focused discussion of ethical considerations in providing care. An ethics chapter in the SOC would enhance clinical guidelines. Aims: We aim to provide a valuable guide for healthcare professionals, and anyone interested in the ethical aspects of clinical support for gender (...) diverse and transgender people of all ages. Recognizing that the WPATH is a global association, we address broad challenges. We offer a reflection on general ethical principles, providing conceptual tools for healthcare providers, patients, and families to navigate the specific challenges they might encounter in transgender health care, in line with WPATH’s worldwide mission and scope. Method: This article employs a descriptive analysis, and our framework of reference is the four principles of biomedical ethics: respect for autonomy, beneficence, nonmaleficence, and justice. Results: The article presents a discussion on the four ethical principles as applied to transgender health care. We address issues such as respect for patient autonomy in decision-making, the role of beneficence and nonmaleficence in clinical interventions, and the importance of justice in equitable treatment and access to care. Some of the ethical concerns we address in this article pertain to the current sociopolitical climate, where there has been increasing legal interference, internationally, for transgender and nonbinary people, particularly youth, seeking medical care. Discussion: We highlight the interplay between ethical principles and clinical practice, underscoring the need for ethical guidance in addressing the diverse challenges faced by healthcare providers and patients in transgender health care. We advocate for continuous refinement of ethical thinking to ensure that transgender health care is not only medically effective but also ethically sound. (shrink)

This paper answers two interpretive questions surrounding belief in God in Thomas Reid’s philosophy, the status question and the detachability question. The former has to do with the type of justification Reid assigns to belief in God – immediate or mediate. The later question is whether anything philosophically significant depends on his belief in God. I argue that, for Reid, belief in God is immediately justified and integral to some parts of his system. Reid’s response to skepticism about God is (...) more complicated and more interesting than many of the contemporary philosophers who, citing Reid as inspiration, also hold that belief in God enjoys immediate justification. In Reid’s hands the approach to belief in God does not compete with inferential justification, does not rely on a special faculty, and foregrounds the developmental character of his epistemology.

Globalization is resulting in complex decisions by businesses as to where and what to produce, while free trade is resulting in a greater menu of choices for consumers, often with the blending of products and goods from various cultures, called ‘glocalization.’ This paper reviews the theories and practices behind these current happenings, which are each economic, politicaleconomic, institutional, and sociological, first by looking at the supply side of why certain countries produce the goods that they do, and then at the (...) demand side, why consumers have particular, cultural tastes and preferences for goods. It also proffers theories to explain firm location and that of intra-industry trade. This occus when countries trade similar products rather than differentiating, as economic theory would suggest. After reviewing the literature, through numerous examples of political-economy and culture, it argues somewhat normatively that differences in culture and goods are a strength to the world community, and that globalization in the end will not likely result in a singular global culture with a uniformity of exactly identical economic goods anytime in the near future.

Inspired by Peter van Inwagen’s “simulacra model” of the resurrection, I investigate whether it could be reasonable to adopt an analogous approach to the problem of evil. Empirically Skeptical Theism, as I call it, is the hypothesis that God shields our lives from irredeemable evils surreptitiously (just as van Inwagen proposes that God shields our bodies from destruction surreptitiously). I argue that EST compares favorably with traditional skeptical theism and with eschatological theodicies, and that EST does not have the negative (...) moral consequences we might suppose. (shrink)

This paper defines the form of prior knowledge that is required for sound inferences by analogy and single-instance generalizations, in both logical and probabilistic reasoning. In the logical case, the first order determination rule defined in Davies (1985) is shown to solve both the justification and non-redundancy problems for analogical inference. The statistical analogue of determination that is put forward is termed 'uniformity'. Based on the semantics of determination and uniformity, a third notion of "relevance" is defined, both logically and (...) probabilistically. The statistical relevance of one function in determining another is put forward as a way of defining the value of information: The statistical relevance of a function F to a function G is the absolute value of the change in one's information about the value of G afforded by specifying the value of F. This theory provides normative justifications for conclusions projected by analogy from one case to another, and for generalization from an instance to a rule. The soundness of such conclusions, in either the logical or the probabilistic case, can be identified with the extent to which the corresponding criteria (determination and uniformity) actually hold for the features being related.

The French existentialist philosopher, Simone de Beauvoir, long ago signalled the potentially empowering force of outdoor exercise and recreation for women, drawing on feminist phenomenological perspectives. Feminist phenomenological research in sport and exercise, however, remains relatively scarce, and this article contributes to a small, developing research corpus by employing a feminist phenomenological theoretical framework to analyse lived experiences of running in ‘public’ space. As feminist theorists have argued, such space is gendered and contested, and women’s mobility remains constrained by fears (...) of harassment and violent attack. Running also generates intense pleasure, however, and embodied empowerment. Drawing on findings from two separate but linked automethodological running research projects, here I explore salient and overlapping themes cohering around lived experience of pleasure and danger in both urban and rural spaces.

We analyze the logical form of the domain knowledge that grounds analogical inferences and generalizations from a single instance. The form of the assumptions which justify analogies is given schematically as the "determination rule", so called because it expresses the relation of one set of variables determining the values of another set. The determination relation is a logical generalization of the different types of dependency relations defined in database theory. Specifically, we define determination as a relation between schemata of first (...) order logic that have two kinds of free variables: (1) object variables and (2) what we call "polar" variables, which hold the place of truth values. Determination rules facilitate sound rule inference and valid conclusions projected by analogy from single instances, without implying what the conclusion should be prior to an inspection of the instance. They also provide a way to specify what information is sufficiently relevant to decide a question, prior to knowledge of the answer to the question. (shrink)

One of the benefits of hypertext in a connected digital environment is the ability to interlink documents. This was part of the hyper-text focused vision of the internet that Tim Berners-Lee was trying to create in the 1990s when he developed the World Wide Web.

Representationalists have routinely expressed skepticism about the idea that inflexible responses to stimuli are to be explained in representational terms. Representations are supposed to be more than just causal mediators in the chain of events stretching from stimulus to response, and it is difficult to see how the sensory states driving reflexes are doing more than playing the role of causal intermediaries. One popular strategy for distinguishing representations from mere causal mediators is to require that representations are decoupled from specific (...) stimulus conditions. I believe this requirement on representation is mistaken and at odds with explanatory practices in sensory ecology. Even when sensory states have the job of coordinating a specific output with a specific input, we can still find them doing the work of representations, carrying information needed for organisms to respond successfully to environmental conditions. We can uncover information at work by intervening specifically on the information conveyed by sensory states, leaving their causal role undisturbed. (shrink)

According to a historically popular view, emotions are normative experiences that ground moral knowledge much as perceptual experiences ground empirical knowledge. Given the analogy it draws between emotion and perception, sentimental perceptualism constitutes a promising, naturalist-friendly alternative to classical rationalist accounts of moral knowledge. In this paper, we consider an important but underappreciated objection to the view, namely that in contrast with perception, emotions depend for their occurrence on prior representational states, with the result that emotions cannot give perceptual-like access (...) to normative properties. We argue that underlying this objection are several specific problems, rooted in the different types of mental states to which emotions may respond, that the sentimental perceptualist must tackle for her view to be successful. We argue, moreover, that the problems can be answered by filling out the theory with several independently motivated yet highly controversial commitments, which we carefully catalogue. The plausibility of sentimental perceptualism, as a result, hinges on further claims sentimental perceptualists should not ignore. (shrink)

A central question, if not the central question, of philosophy of perception is whether sensory states have a nature similar to thoughts about the world, whether they are essentially representational. According to the content view, at least some of our sensory states are, at their core, representations with contents that are either accurate or inaccurate. Tyler Burge’s Origins of Objectivity is the most sustained and sophisticated defense of the content view to date. His defense of the view is problematic in (...) several ways. The most significant problem is that his approach does not sit well with mainstream perceptual psychology. (shrink)

Teleological accounts of sensory normativity treat normal functioning for a species as a standard: sensory error involves departure from normal functioning for the species, i.e. sensory malfunction. Straightforward reflection on sensory trade-offs reveals that normal functioning for a species can exhibit failures of accuracy. Acknowledging these failures of accuracy is central to understanding the adaptations of a species. To make room for these errors we have to go beyond the teleological framework and invoke the notion of an ideal observer from (...) vision science. The notion of an ideal observer also sheds light on the important distinction between sensory malfunction and sensory limitation. (shrink)

: Agents are enkratic when they intend to do what they believe they should. That rationality requires you to be enkratic is uncontroversial, yet you may be enkratic in a way that does not exhibit any rationality on your part. Thus, what I call the enkratic requirement demands that you be enkratic in the right way. In particular, I will argue that it demands that you base your belief about what you should do and your intention to do it on (...) the same considerations. The idea is that, if you base your belief and your intention on different considerations, then you are inconsistent in your treatment of those considerations as reasons. The enkratic requirement demands that you be enkratic by treating considerations consistently as reasons. (shrink)

What role does the imagination play in scientific progress? After examining several studies in cognitive science, I argue that one thing the imagination does is help to increase scientific understanding, which is itself indispensable for scientific progress. Then, I sketch a transcendental justification of the role of imagination in this process.

A common objection to representationalism is that a representationalist view of phenomenal character cannot accommodate the effects that shifts in covert attention have on visual phenomenology: covert attention can make items more visually prominent than they would otherwise be without altering the content of visual experience. Recent empirical work on attention casts doubt on previous attempts to advance this type of objection to representationalism and it also points the way to an alternative development of the objection.

Appeals to the idea of human nature are frequent in the voluminous literature on the ethics of enhancing human beings through biotechnology. Two chief concerns about the impact of enhancements on human nature have been voiced. The first is that enhancement may alter or destroy human nature. The second is that if enhancement alters or destroys human nature, this will undercut our ability to ascertain the good because, for us, the good is determined by our nature. The first concern assumes (...) that altering or destroying human nature is in itself a bad thing. The second concern assumes that human nature provides a standard without which we cannot make coherent, defensible judgments about what is good. I will argue (1) that there is nothing wrong, per se, with altering or destroying human nature, because, on a plausible understanding of what human nature is, it contains bad as well as good characteristics and there is no reason to believe that eliminating some of the bad would so imperil the good as to make the elimination of the bad impermissible, and (2) that altering or destroying human nature need not result in the loss of our ability to make judgments about the good, because we possess a conception of the good by which we can and do evaluate human nature. I will argue that appeals to human nature tend to obscure rather than illuminate the debate over the ethics of enhancement and can be eliminated in favor of more cogent considerations. (shrink)
