Taking a quick look at game theory, rational egoism and the evolution of fairness.

Robustness has long been recognized as an important parameter for evaluating game-theoretic results, but talk of ‘robustness’ generally remains vague. What we offer here is a graphic measure for a particular kind of robustness (‘matrix robustness’), using a three-dimensional display of the universe of 2 × 2 game theory. In such a measure specific games appear as specific volumes (Prisoner’s Dilemma, Stag Hunt, etc.), allowing a graphic image of the extent of particular game-theoretic effects in terms of those games. The (...) measure also allows for an easy comparison between different effects in terms of matrix robustness. Here we use the measure to compare the robustness of Tit for Tat’s well-known success in spatialized games (Axelrod, R. (1984). The evolution of cooperation . New York: Basic Books; Grim, P. et al. (1998). The philosophical computer: Exploratory essays in philosophical computer modeling . Cambridge, Mass: MIT Press) with the robustness of a recent game-theoretic model of the contact hypothesis regarding prejudice reduction (Grim et al. 2005. Public Affairs Quarterly, 19 , 95–125).

Is capitalism inherently predatory? Must there be winners and losers? Is public interest outdated and free-riding rational? Is consumer choice the same as self-determination? Must bargainers abandon the no-harm principle? Prisoners of Reason recalls that classical liberal capitalism exalted the no-harm principle. Although imperfect and exclusionary, modern liberalism recognized individual human dignity alongside individuals' responsibility to respect others. Neoliberalism, by contrast, views life as ceaseless struggle. Agents vie for scarce resources in antagonistic competition in which every individual seeks dominance. This (...) political theory is codified in non-cooperative game theory; the neoliberal citizen and consumer is the strategic rational actor. Rational choice justifies ends irrespective of means. Money becomes the medium of all value. Solidarity and good will are invalidated. Relationships are conducted on a quid pro quo basis. However, agents can freely opt out of this cynical race to the bottom by embracing a more expansive range of coherent action. (shrink)

The iterated Prisoner’s Dilemma has become the standard model for the evolution of cooperative behavior within a community of egoistic agents, frequently cited for implications in both sociology and biology. Due primarily to the work of Axelrod (1980a, 198Ob, 1984, 1985), a strategy of tit for tat (TFT) has established a reputation as being particularly robust. Nowak and Sigmund (1992) have shown, however, that in a world of stochastic error or imperfect communication, it is not TFT that finally triumphs in (...) an ecological model based on population percentages (Axelrod and Hamilton 1981), but ‘generous tit for tat’ (GTFT), which repays cooperation with a probability of cooperation approaching 1 but forgives defection with a probability of l/3. In this paper, we consider a spatialized instantiation of the stochastic Prisoner’s Dilemma, using two-dimensional cellular automata (Wolfram, 1984, 1986; Gutowitz, 1990) to model the spatial dynamics of populations of competing strategies. The surprising result is that in the spatial model it is not GIFT but still more generous strategies that are favored. The optimal strategy within this spatial ecology appears to be a form of ‘bending over backwards’, which returns cooperation for defection with a probability of 2/3 - a rate twice as generous as GTFT.

A dialogue arguing that morality has an objective basis in the mathematical object describing the "tit for tat" game theory. To play the game, a contractual obligation is freely made to cooperate and to fairly distribute the gains. Failure to meet these obligations results in social punishment.

Talk of ‘robustness’ remains vague, despite the fact that it is clearly an important parameter in evaluating models in general and game-theoretic results in particular. Here we want to make it a bit less vague by offering a graphic measure for a particular kind of robustness— ‘matrix robustness’— using a three dimensional display of the universe of 2 x 2 game theory. In a display of this form, familiar games such as the Prisoner’s Dilemma, Stag Hunt, Chicken and Deadlock appear (...) as volumes, making comparison easy regarding the extent of different game-theoretic effects. We illustrate such a comparison in robustness between the triumph of Tit for Tat in a spatialized environment (Grim 1995, Grim, Mar, and St. Denis 1998) and a spatialized modeling of the Contact Hypothesis regarding prejudice reduction (Grim, et. al 2005a, 2005b). The geometrical representation of relative robustness also offers a possibility for links between geometrical theorems and results regarding robustness in game theory. (shrink)

In contrast to Axelrod’s advice “don’t be envious” it is argued that the emotion of envy may enhance cooperation. TIT FOR TAT does exhibit a certain degree of envy. But, it does so in inconsistent ways. Two variants of TIT FOR TAT are introduced and their strategic properties are analyzed. Both generate the very same actual play as TIT FOR TAT in a computer tournament without noise. However, if noise is introduced they display some greater degree of stability. This is (...) due to the fact that they form, in a prisoner’s dilemma supergame with suitable parameters, an equilibrium with themselves that is subgame perfect or (in case of the first strategy) close to subgame perfect. It is additionally argued that these strategies are exceptionally clear and comprehensible to others in that they conform to well known real live behavior patterns. (shrink)

Recent discoveries of semantic compositionality in Japanese tits have enlivened the discussions on the presence of this phenomenon in wild animal communication. Data on semantic compositionality in wild apes are lacking, even though language experiments with captive apes have demonstrated they are capable of semantic compositionality. In this paper, I revisit the study by Boesch (Hum. Evol. 6:81–89, 1991) who investigated drumming sequences by an alpha male in a chimpanzee (_Pan troglodytes_) community in the Taï National Park, Côte d’Ivoire. A (...) reanalysis of the data reveals that the alpha male produced semantically compositional combined messages of travel direction change and resting period initiation. Unlike the Japanese tits, the elements of the compositional expression were not simply juxtaposed but displayed structural reduction, while one of the two elements in the expression coded the meanings of both elements. These processes show relative resemblance to blending and fusion in human languages. Also unlike the tits, the elements of the compositional expression did not have a fixed order, although there was a fixed distribution of drumming events across the trees used for drumming. Because the elements of the expression appear to carry verb-like meanings, the compositional expression also resembles simple verb-verb constructions and short paratactic combinations of two clauses found across languages. In conclusion, the reanalysis suggests that semantic compositionality and phenomena resembling paratactic combinations of two clauses might have been present in the communication of the last common ancestor of chimpanzees and humans, not necessarily in the vocal modality.

Artificial intelligence has arrived. In the online world it is already a part of everyday life, sitting invisibly behind a wide range of search engines and online commerce sites. It offers huge potential to enable more efficient and effective business and government but the use of artificial intelligence brings with it important questions about governance, accountability and ethics. Realising the full potential of artificial intelligence and avoiding possible adverse consequences requires societies to find satisfactory answers to these questions. This report (...) sets out some possible approaches, and describes some of the ways government is already engaging with these issues. (shrink)

When examining the human being as a conscious being, we are still to arrive at an understanding of, firstly, the conditions required whereby physical processes give rise to consciousness and secondly, how consciousness is something fundamental to life as an intrinsic part of nature. Humans are complex organisms with myriad interacting systems whereby the convergence of the activities toward the support and development of the whole organism requires a high level of organisation. Though what accounts for the dynamic unity of (...) the human being? From an empirical perspective the question remains unanswered. The aim of this paper is to conceptually establish a fundamental biophysical organising principle to account for the unity and organisation of the human being. To this end I draw from David Bohm’s interpretation of quantum theory to provide an adapted and adjunct conceptual scheme in the form of a Triple-Aspect-Theory (TAT) of Being as a grounding ontology. David Bohm presented a holistic view of two interwoven orders of existence defined as the Explicate material world and the Implicate (quantum) enfolded world from which the former materialises. Consistent with David Bohm’s idea that matter at a fundamental level consists of a kind of protointelligence, the TAT facilitates a perspective based on aspect conditions of the human organism intended to furnish an explanation of the constitutive mechanism (TAT) inherent in the evolving human being. The TAT operates as an organising principle by which evolution inherently proceeds and maintains itself in an interactive relation between the Implicate and Explicate orders. The accumulated effect of natural selection is to produce adaptations, but without an organising principle: ‘Consciousness’, ‘Body-of-Experience’ and ‘Intellect-Reflective’ (the terms for the engaged coexistent aspects of being) it is argued could not occur.

Previous efforts to bring the Hegelian dialectic closer to a clarification give reason for skepticism. The question: "What is dialectic", according to Dieter Henrich, "has remained without an answer so far". Hegel's objective-idealistic program is, however, so much linked to the possibility of a dialectical logic that it is an urgent desideratum to gain clarity about the stringency of dialectical argumentation. But this is only possible on the basis of a theory of dialectic. Hegel's own reflection on methods cannot be (...) considered sufficient in this respect. It does not enable us to defend the dialectical procedure against objections or to answer questions of method. In the following, a detailed reconstruction of the dialectic of 'being' and 'nothing' in Hegel's 'Science of Logic' will reveal basic structures of dialectical argumentation. As will be shown, antinomic structures play a key role. Such a 'reconstruction', however, will not be a simple confirmation of Hegelian texts, but will always have the character of a critique. In fact, it will turn out that in comparison with Hegel's development of categories, radical revisions are to be expected. ----- Bisherige Bemühungen, das Verfahren Hegelscher Dialektik einer Klärung näherzubringen, geben Anlass zur Skepsis. Die Frage: „Was ist Dialektik?“, so Dieter Henrich, sei „bisher ohne Antwort geblieben“. Das objektiv-idealistische Programm Hegels ist indes so sehr mit der Möglichkeit einer dialektischen Logik verknüpft, daß über die Stringenz dialektischer Argumentation Klarheit zu gewinnen ein dringliches Desiderat darstellt. Das aber ist nur auf der Grundlage einer Theorie der Dialektik möglich. Hegels eigene Methodenreflexion kann diesbezüglich nicht als zureichend erachtet werden. Sie versetzt uns nicht in die Lage, das dialektische Verfahren gegen Einwände zu verteidigen oder Methodenfragen zu beantworten. Im Folgenden sollen in einer detaillierten Rekonstruktion der Dialektik von ‘Sein’ und ‘Nichts’ in Hegels ‘Wissenschaft der Logik’ Grundstrukturen dialektischer Argumentation sichtbar gemacht werden. Wie gezeigt wird, kommt dabei antinomischen Strukturen eine Schlüsselfunktion zu. Eine solche 'Rekonstruktion' wird allerdings nicht eine umstandslose Bestätigung der Hegelschen Textvorlage sein können, sondern immer auch den Charakter einer Kritik haben. In der Tat wird sich ergeben, daß im Vergleich mit Hegels Kategorienentwicklung einschneidende Revisionen zu gewärtigen sind. (shrink)

Drawing on the well-established understanding of the zombie as metaphor for the deadening effects of consumer capitalism, this chapter seeks to account for three distinct changes that contextualise 21st century zombie fiction. The first is situational: the global economic crisis has amplified the anxieties that inspired Romero's critique of consumer capitalism in Dawn of the Dead (1978). The second is intellectual: as Chapman and Anderson (2011) note, there has been an “explosion of research on all aspects of disgust” in recent (...) years. The third concerns the subgenre itself: zombies have become increasingly sexualised since the late 1990s. These issues intersect in a numerous recent zombie films - including Zombie Strippers! (2008), Zombies! Zombies! Zombies! (2008), Big Tits Zombie (2010), and Zombies Vs Strippers (2012) - that are centred around or within strip clubs. Stripping epitomises the logic of consumer capitalism, offering tantalising promises but little physical satisfaction. Stripping translates sexual desire into a voyeuristic transaction, evacuated of corporeal messiness. The zombie’s decomposing body epitomises disgust, and its presence in the strip-club disturbs the fantasy typically provided within that context. In the zombie infected strip-club, intimate contact is damaging rather than desirous. In these respects, zombies hypostatize numerous tensions that are usually masked by fantasy and financial exchange. In doing so, these zombies reify the horrors of late capitalism. Their disgusting bodies disrupt the foundational logic of consumerism qua desire. (shrink)

Name der Zeitschrift: Nietzsche-Studien Jahrgang: 44 Heft: 1 Seiten: 231-266. -/- Abstract: In this essay I defend my interpretation of the unheard words that Zarathustra whispers into Life’s ear in “The Other Dance Song” and that have long kept commentators puzzled. I argue that what Zarathustra whispers is that he knows that Life is pregnant with his child. Zarathustra’s ability to make Life pregnant depends on his overcoming of Eternal Recurrence which threatens to strangle him with disgust of human beings (...) and all of existence, thereby making him into a spiritual eunuch whose will has turned into not-willing. The insemination of Life is a transfiguring act that raises Life from her blind animality (or materiality) into the level of a spiritually fertile existence, which is the condition of human freedom. This act is performed with the help of our capacity for theoretical knowledge, which is why it requires love of Wisdom. However, love of Wisdom can make us infertile, and thus unfree, when pursued for its own sake (knowledge can choke). I conclude by considering who might be the child of Zarathustra and Life. -/- Zusammenfassung: In diesem Aufsatz verteidige ich meine Interpretation der unhörbaren Wörter, die Zarathustra in „Das andere Tanzlied“ in das Ohr des Lebens flüstert und seit langem Kommentatoren ratlos machen. Was Zarathustra flüstert, ist, so meine These, dass er weiß, dass das Leben mit seinem Kind schwanger ist. Zarathustras Fähigkeit, das Leben zu schwängern, hängt von seiner Überwindung des Gedankens der ewigen Wiederkehr ab, der ihn durch den Überdruss am Menschen und an allem Dasein zu erwürgen bedroht und ihn dabei zu einem spirituellen Eunuchen macht, dessen Wollen zum Nicht-Wollen geworden ist. Die Befruchtung des Lebens ist eine umgestaltende Tat, die das Leben von seiner blinden Tiernatur (oder Stofflichkeit) auf die Ebene eines spirituell fruchtbaren Daseins erhebt, was die Voraussetzung menschlicher Freiheit ist. Dieser Akt wird mit Hilfe unserer Fähigkeit zu theoretischem Wissen ausgeführt, weshalb er Liebe zur Weisheit erfordert. Liebe zur Weisheit kann uns jedoch unfruchtbar und damit unfrei machen, wenn sie um ihrer selbst willen verfolgt wird (Wissen kann ersticken). Ich schließe mit der Überlegung ab, wer Zarathustras und des Lebens Kind sein könnte. (shrink)

Die Zeiten, in denen Kausalität das Charakteristikum von Wissenschaftlichkeit war, scheinen sich ihrem Ende zu nähern. Seit dem Beginn unseres Jahrhunderts ist eine seit langem schwelende Krise des herkömmlichen Kausalitätsverständnisses in den Naturwissenschaften unübersehbar zum Ausdruck gekommen. Dessen ungeachtet halten jedoch viele Wissenschaftstheoretiker an Kausalitätsvorstellungen als vermeintlich unverzichtbarem Analyseinstrument fest. In Kritik dieser Tendenz zur Verkennung eines grundlegenden Bedeutungsverlustes wird der historische Verdrängungsprozess von Kausalitätsvorstellungen unter den Stichworten der Entfinalisierung und Entsubstantialisierung nachgezeichnet. Aus der Perspektive geschichtlicher Rekonstruktion handelt es sich (...) bei den gegenwärtigen Vorstellungen um den letzten Rest einer unvergleichlich reichhaltigeren ursprünglichen kausalen Begrifflichkeit. Am Beispiel der heute wohl weitverbreitetsten, auf C. G. Hempel zurückgehenden Vorstellung werden die wichtigsten Merkmale der kausalen Relation diskutiert. Im Ergebnis zeigt sich, dass für das naturwissenschaftliche Kausalitätsverständnis, soweit es sich auf einen Begriff bringen lässt, in der Tat ein reduzierter Sinngehalt der Kategorie der Verursachung in kausalen Erklärungen, eine begrenzte Anwendbarkeit sowie ein reduzierter Geltunganspruch typisch sind. Die Grenzen naturwisseschaftlicher Kausalitätsvorstellungen betreffen deren' strenge begriffliche Fassung, nicht jedoch ihre Brauchbarkeit als heuristische Forschungsmaxime in Situationen, in denen unerwartete Phänomene auftreten oder Phänomene ausbleiben, mit denen man zuvor fest gerechnet hat. Für diese Situationen ist die Überlegung, was der Fall gewesen wäre, wenn eine Ursache nicht eingetreten wäre, in besonderer Weise bezeichnend. Welche Relevanz dieser Kausalitätsvorstellung zukünftig zukommen wird, hängt wesentlich vom Charakter der weiteren Wissenschaftsentwicklung ab. (shrink)

What is the proper role for scientists in policymaking? This paper explores various roles that scientists can play, with an eye to questions that these roles raise about value-neutrality and technocracy. Where much philosophical literature is concerned with the conduct of research or the transmission of research results to policymakers, I am interested in various non-research roles that scientists take on in policymaking. These include raising the alarm on issues, framing and conceptualising problems, formulating potential policies, assessing policy options for (...) expected efficacy, and more. I consider examples from climate change and Covid-19 policymaking. My intention is to encourage philosophers to expand their interest in values in science out from the conduct of research to the wide array of roles that scientists play in policymaking. The paper is therefore an overview of the landscape of potential research questions, rather than a presentation of a single argument. (shrink)

This paper explains what it is to believe something for a reason. My thesis is that you believe something for a reason just in case the reason non-deviantly causes your belief. In the course of arguing for my thesis, I present a new argument that reasons are causes, and offer an informative account of causal non-deviance.

What we value, like, endorse, want, and prefer changes over the course of our lives. Richard Pettigrew presents a theory of rational decision making for agents who recognise that their values will change over time and whose decisions will affect those future times.

Ontologies are being used increasingly to promote the reusability of scientific information by allowing heterogeneous data to be integrated under a common, normalized representation. Definitions play a central role in the use of ontologies both by humans and by computers. Textual definitions allow ontologists and data curators to understand the intended meaning of ontology terms and to use these terms in a consistent fashion across contexts. Logical definitions allow machines to check the integrity of ontologies and reason over data annotated (...) with ontology terms to make inferences that promote knowledge discovery. Therefore, it is important not only to include in ontologies multiple types of definitions in both formal and in natural languages, but also to ensure that these definitions meet good quality standards so they are useful. While tools such as Protégé can assist in creating well-formed logical definitions, producing good definitions in a natural language is still to a large extent a matter of human ingenuity supported at best by just a small number of general principles. For lack of more precise guidelines, definition authors are often left to their own personal devices. This paper aims to fill this gap by providing the ontology community with a set of principles and conventions to assist in definition writing, editing, and validation, by drawing on existing definition writing principles and guidelines in lexicography, terminology, and logic.

How do we ascribe subjective probability? In decision theory, this question is often addressed by representation theorems, going back to Ramsey (1926), which tell us how to define or measure subjective probability by observable preferences. However, standard representation theorems make strong rationality assumptions, in particular expected utility maximization. How do we ascribe subjective probability to agents which do not satisfy these strong rationality assumptions? I present a representation theorem with weak rationality assumptions which can be used to define or measure (...) subjective probability for partly irrational agents. (shrink)

Orthodox Bayesianism is a highly idealized theory of how we ought to live our epistemic lives. One of the most widely discussed idealizations is that of logical omniscience: the assumption that an agent’s degrees of belief must be probabilistically coherent to be rational. It is widely agreed that this assumption is problematic if we want to reason about bounded rationality, logical learning, or other aspects of non-ideal epistemic agency. Yet, we still lack a satisfying way to avoid logical omniscience within (...) a Bayesian framework. Some proposals merely replace logical omniscience with a different logical idealization; others sacrifice all traits of logical competence on the altar of logical non-omniscience. We think a better strategy is available: by enriching the Bayesian framework with tools that allow us to capture what agents can and cannot infer given their limited cognitive resources, we can avoid logical omniscience while retaining the idea that rational degrees of belief are in an important way constrained by the laws of probability. In this paper, we offer a formal implementation of this strategy, show how the resulting framework solves the problem of logical omniscience, and compare it to orthodox Bayesianism as we know it.

We have begun work on two separate but related ontologies for the study of neurological diseases. The first, the Neurological Disease Ontology (ND), is intended to provide a set of controlled, logically connected classes to describe the range of neurological diseases and their associated signs and symptoms, assessments, diagnoses, and interventions that are encountered in the course of clinical practice. ND is built as an extension of the Ontology for General Medical Sciences — a high-level candidate OBO Foundry ontology that (...) provides a set of general classes that can be used to describe general aspects of medical science. ND is being built with classes utilizing both textual and axiomatized definitions that describe and formalize the relations between instances of other classes within the ontology itself as well as to external ontologies such as the Gene Ontology, Cell Ontology, Protein Ontology, and Chemical Entities of Biological Interest. In addition, references to similar or associated terms in external ontologies, vocabularies and terminologies are included when possible. Initial work on ND is focused on the areas of Alzheimer’s and other diseases associated with dementia, multiple sclerosis, and stroke and cerebrovascular disease. Extensions to additional groups of neurological diseases are planned. The second ontology, the Neuro-Psychological Testing Ontology (NPT), is intended to provide a set of classes for the annotation of neuropsychological testing data. The intention of this ontology is to allow for the integration of results from a variety of neuropsychological tests that assay similar measures of cognitive functioning. Neuro-psychological testing is an important component in developing the clinical picture used in the diagnosis of patients with a range of neurological diseases, such as Alzheimer’s disease and multiple sclerosis, and following stroke or traumatic brain injury. NPT is being developed as an extension to the Ontology for Biomedical Investigations. (shrink)

Infinitists argue that their view outshines foundationalism because infinitism can, whereas foundationalism cannot, explain two of epistemic justification’s crucial features: it comes in degrees and it can be complete. I present four different ways that foundationalists could make sense of those two features of justification, thereby undermining the case for infinitism.

Crispin Wright’s entitlement theory holds that we have non-evidential justification for accepting propositions of a general type––which Wright calls “cornerstones”––that enables us to acquire justification for believing other propositions––those that we take to be true on the grounds of ordinary evidence. Entitlement theory is meant by Wright to deliver a forceful response to the sceptic who argues that we cannot justify ordinary beliefs. I initially focus on strategic entitlement, which is one of the types of entitlement that Wright has described (...) in more detail. I suggest that it is dubious that we are strategically entitled to accept cornerstones. After this, I focus on entitlement in general. I contend that, in important cases, non-evidential justification for accepting cornerstones cannot secure evidential justification for believing ordinary propositions. My argument rests on a probabilistic regimentation of the so-called “leaching problem”. (shrink)

Because factory-farmed meat production inflicts gratuitous suffering upon animals and wreaks havoc on the environment, there are morally compelling reasons to become vegetarian. Yet industrial plant agriculture causes the death of many field animals, and this leads some to question whether consumers ought to get some of their protein from certain kinds of non factory-farmed meat. Donald Bruckner, for instance, boldly argues that the harm principle implies an obligation to collect and consume roadkill and that strict vegetarianism is thus immoral. (...) But this argument works only if the following claims are true: all humans have access to roadkill, roadkill would go to waste if those who happen upon it don’t themselves consume it, it’s impossible to harvest vegetables without killing animals, the animals who are killed in plant production are all-things-considered harmed by crop farming, and the best arguments for vegetarianism all endorse the harm principle. As I will argue in this paper, each claim is deeply problematic. Consequently, in most cases, humans ought to strictly eat plants and save the roadkill for cats. (shrink)

The idea that there are some facts that call for explanation serves as an unexamined premise in influential arguments for the inexistence of moral or mathematical facts and for the existence of a god and of other universes. This book is the first to offer a comprehensive and critical treatment of this idea. It argues that calling for explanation is a sometimes-misleading figure of speech rather than a fundamental property of facts.

Our aim in the present paper is to investigate, from the standpoint of truth-theoretic semantics, English tense, temporal designators and quantifiers, and other expressions we use to relate ourselves and other things to the temporal order. Truth-theoretic semantics provides a particularly illuminating standpoint from which to discuss issues about the semantics of tense, and their relation to thoughts at, and about, times. Tense, and temporal modifiers, contribute systematically to conditions under which sentences we utter are true or false. A Tarski-style (...) truth-theoretic semantics, by requiring explicitly represented truth conditions, helps to sharpen questions about the function of tense, and to deepen our insight into the contribution the tenses and temporal modifiers make to what we say by using them.

What follows is a first step towards an ontology of conscious mental processes. We provide a theoretical foundation and characterization of conscious mental processes based on a realist theory of intentionality and using BFO as our top-level ontology. We distinguish three components of intentional mental process: character, directedness, and objective referent, and describe several features of the process character and directedness significant to defining and classifying mental processes. We arrive at the definition of representational mental process as a process that (...) is the bringing into being, sustaining, modifying, or terminating of a mental representation. We conclude by outlining some benefits and applications of this approach. (shrink)

After a fatal police shooting in the United States, it is typical for city and police officials to view the family of the deceased through the lens of the law. If the family files a lawsuit, the city and police department consider it their legal right to defend themselves and to treat the plaintiffs as adversaries. However, reparations and the concept of “reparative justice” allow authorities to frame police killings in moral rather than legal terms. When a police officer kills (...) a person who was not liable to this outcome, officials should offer monetary reparations, an apology, and other redress measures to the victim’s family. To make this argument, the article presents a philosophical account of non-liability hailing from self-defense theory, centering the distinction between reasonableness and liability. Reparations provide a non-adversarial alternative to civil litigation after a non-liable person has been killed by a police officer. In cases where the officer nevertheless acted reasonably, “institutional agent-regret” rather than moral responsibility grounds the argument for reparations. Throughout the article, it is argued that there are distinct racial wrongs both when police kill a non-liable black person and when family members of a black victim are treated poorly by officials in the civil litigation process.

The most promising contemporary form of epistemic scientific realism is based on the following intuition: Belief should be directed, not toward theories as wholes, but toward particular theoretical constituents that are responsible for, or deployed in, key successes. While the debate on deployment realism is quite fresh, a significant degree of confusion has already entered into it. Here I identify five criteria that have sidetracked that debate. Setting these distractions aside, I endeavor to redirect the attention of both realists and (...) non-realists to the fundamental intuition above. In more detail: I show that Stathis Psillos (1999) has offered an explicit criterion for picking out particular constituents, which, contrary to Kyle Stanford’s (2006a) criticisms, neither assumes the truth of theories nor requires hindsight. I contend, however, that, in Psillos’s case studies, Psillos has not successfully applied his explicit criterion. After clarifying the various alternative criteria at work (in those case studies and in a second line of criticism offered by Stanford), I argue that, irrespective of Stanford’s criticisms, the explicit criterion Psillos does offer is not an acceptable one. Nonetheless, the deployment realist’s fundamental intuition withstands all of these challenges. In closing, I point in a direction toward which I’ve elsewhere focused, suggesting that, despite the legitimacy and applicability of the deployment realist’s intuition, the historical threat that prompted it remains.

Philosophers of physics have long debated whether the Past State of low entropy of our universe calls for explanation. What is meant by “calls for explanation”? In this article we analyze this notion, distinguishing between several possible meanings that may be attached to it. Taking the debate around the Past State as a case study, we show how our analysis of what “calling for explanation” might mean can contribute to clarifying the debate and perhaps to settling it, thus demonstrating the (...) fruitfulness of this analysis. Applying our analysis, we show that two main opponents in this debate, Huw Price and Craig Callender, are, for the most part, talking past each other rather than disagreeing, as they employ different notions of “calling for explanation”. We then proceed to show how answering the different questions that arise out of the different meanings of “calling for explanation” can result in clarifying the problems at hand and thus, hopefully, to solving them.

The “somewhat vague, intuitive” notion from computability theory of an effective procedure (method) or algorithm can be fairly precisely defined even if it is not sufficiently formal and precise to belong to mathematics proper (in a narrow sense)—and even if (as many have asserted) for that reason the Church–Turing thesis is unprovable. It is proved logically that the class of effective procedures is not decidable, i.e., that no effective procedure is possible for ascertaining whether a given procedure is effective. This (...) undecidability result is proved directly from the notion itself of an effective procedure, without reliance on any (partly) mathematical lemma, conjecture, or thesis invoking recursiveness or Turing-computability. In fact, there is no reliance on anything very mathematical. The proof does not even appeal to a precise definition of ‘effective procedure’. Instead, it relies solely and entirely on a basic grasp of the intuitive notion of an effective procedure. Though the result that effectiveness is undecidable is not surprising, it is also not without significance. It has the consequence, for example, that the solution to a decision problem, if it is to be complete, must be accompanied by a separate argument that the proposed ascertainment procedure invariably terminates with the correct verdict.

In recent literature, panpsychism has been defended by appeal to two main arguments: first, an argument from philosophy of mind, according to which panpsychism is the only view which successfully integrates consciousness into the physical world (Strawson 2006; Chalmers 2013); second, an argument from categorical properties, according to which panpsychism offers the only positive account of the categorical or intrinsic nature of physical reality (Seager 2006; Adams 2007; Alter and Nagasawa 2012). Historically, however, panpsychism has also been defended by appeal (...) to a third argument based on considerations about the nature and observability of causation. This argument has not been much discussed in recent times. Here is a concise version from William James: "… the concrete perceptual flux, taken just as it comes, offers in our own activity-situations perfectly comprehensible instances of causal agency … If we took these experiences as the type of what actual causation is, we should have to ascribe to cases of causation outside of our life, to physical cases also, an inwardly experiential nature. In other words, we should have to espouse a so-called “pan-psychic” philosophy" (James 1911: 218). James here suggests that we have direct experience of causation in our own agency. He thereby directly contradicts David Hume, who famously denied that we have any experience of causation. James goes on to claim that if this experience is representative of causation in general, it follows that all causation is mental, and that panpsychism is true. This kind of argument for panpsychism can be called the argument from (experience of) causation. This chapter offers, first, a history of this argument and arguments closely related to it, and second, an analysis of the argument – is it valid, are its premises in any way defensible, and how does it relate to the other, more popular arguments for panpsychism from philosophy of mind and categorical properties?

Several philosophers have proposed Knowledge-Based Decision Theories (KDTs)—theories that require agents to maximize expected utility as yielded by utility and probability functions that depend on the agent’s knowledge. Proponents of KDTs argue that such theories are motivated by Knowledge-Reasons norms that require agents to act only on reasons that they know. However, no formal derivation of KDTs from Knowledge-Reasons norms has been suggested, and it is not clear how such norms justify the particular ways in which KDTs relate knowledge and (...) rational action. In this paper, I suggest a new axiomatic method for justifying KDTs and providing them with stronger normative foundations. I argue that such theories may be derived from constraints on the relation between knowledge and preference, and that these constraints may be evaluated relative to intuitions regarding practical reasoning. To demonstrate this, I offer a representation theorem for a KDT proposed by Hawthorne and Stanley (2008) and briefly evaluate it through its underlying axioms. -/- In section 1, I present knowledge-based decision theories generally and the versions of such theories suggested in the literature. In section 2, I argue that KDTs and theories of practical reasoning conjoined with Knowledge-Reasons norms generate constraints on the same relation—the relation between knowledge and preference. In section 3, I present a formal framework in which constraints on this relation may be expressed and from which KDTs may be derived. In section 4, I present a representation theorem for a specific KDT. In section 5, I briefly evaluate the axioms of the theory, and in section 6, I conclude. (shrink)

This is a discussion of the state of discussion on pragmatic reasons for belief.

In this paper, I develop a metasemantics for relaxed moral realism. More precisely, I argue that relaxed realists should be inferentialists about meaning and explain that the role of evaluative moral vocabulary is to organise and structure language exit transitions, much as the role of theoretical vocabulary is to organise and structure language entry transitions.

An important method for finding the optimal solution for linear and nonlinear models is the graphical method, which is used if the linear or nonlinear mathematical model contains one, two, or three variables. The models that contain only two variables are among the most models for which the optimal solution has been obtained graphically, whether these models are linear or non-linear in references and research that are concerned with the science of operations research, when the data of the issue under (...) study is classical data. In this research, we will present a study through, which we present the graphical method for solving Neutrosophical nonlinear models in the following case: A nonlinear programming issue, the objective function is a nonlinear function, and the constraints are linear functions. Note that we can use the same method if (i) the objective function follower is a linear follower and the constraints are nonlinear; (ii) the objective function is a non-linear follower and the constraints are non-linear. In the three cases, the nonlinear models are neutrosophic, and as we know, the mathematical model is a nonlinear model if any of the components of the objective function or the constraints are nonlinear expressions, and the nonlinear expressions may be in both. At the left end of the constraints are neutrosophic values, at least one or all of them. Then, the possible solutions to the neutrosophic nonlinear programming problem are the set of rays that fulfills all the constraints. As for the region of possible solutions, it is the region that contains all the rays that fulfill the constraints. The optimal solution is the beam that fulfills all constraints and at which the function reaches a maximum or minimum value, depending on the nature of the issue under study (noting that it is not necessary to be alone).

This paper is an English version of the paper that was published in German under the title: "Über die Aussichten erfolgreicher Beweise für Theismus oder Atheismus". My English paper was translated into German by Gabriele Schlegel. -/- The aim of this paper is to examine the prospects for proofs or successful arguments for the existence or non-existence of God.

Many of our attitudes are non-culpable: there was nothing that we should have done to avoid holding them. I argue that we can still be blameworthy for non-culpable attitudes: they can impair our relationships in ways that make our full practice of apology and forgiveness intelligible. My argument poses a new challenge to indirect voluntarists, who attempt to reduce all responsibility for attitudes to responsibility for prior actions and omissions. Rationalists, who instead explain attitudinal responsibility by appeal to reasons-responsiveness, can (...) make sense of blameworthiness for non-culpable attitudes. In response, voluntarists could propose a revision of our actual practices. This would lead us into a quite different debate. (shrink)

While there are satisfactory answers to the question “How should we teach children mathematics?”, there are no satisfactory answers to the question “What mathematics should we teach children?”. This paper provides an answer to the last question for preschool children (early childhood), although the answer is also applicable to older children. This answer, together with an appropriate methodology on how to teach mathematics, gives a clear conception of the place of mathematics in the children’s world and our role in helping (...) children develop their mathematical abilities. Briefly, children’s mathematics consists of the world of children’s internal activities that they eventually purposefully organize in order to understand and control the outside world and organize their overall activities in it. We need to support a child in mathematical activities that she does spontaneously and in which she shows interest, and we need to teach her mathematics that she is interested in developing through these activities. In doing so, we must be fully aware that the child’s mathematics is part of the child’s world of internal activities and is not outside of it. We help the child develop mathematical abilities by developing them in the context of her world and not outside of it. From the point of view of this conception, the standards established today are limiting and too focused on numbers and geometric figures: these topics are too prominent and elaborated, and other mathematical contents are subordinated to them. Adhering to the standards, we drastically limit the mathematics of the child’s world, hamper the correct mathematical development of a child, and we can turn her away from mathematics. (shrink)

Humean arguments from evil are some of the most powerful arguments against Theism. They take as their data what we know about good and evil. And they argue that some rival to Theism better explains, or otherwise predicts, that data than Theism. However, this paper argues that there are many problems with various methods for defending Humean arguments. I consider Philo’s original strategy; modern strategies in terms of epistemic probability; phenomenological strategies; and strategies that appeal to scientific and metaphysical explanations. (...) None of these methods have been sufficiently developed to provide a clear and distinctive defense of Humean arguments. Defenders of Humean arguments need to spend more time on the underlying methodology of their arguments. (shrink)

Are there any facts that call for explanation? According to one possible view, all facts call for explanation; according to another, none do. This paper is concerned with an intermediate view according to which some facts call for explanation and others do not. Such a view requires explaining what makes some facts call for explanation and not others. In this paper, I explore a neglected proposal, inspired by the work of George Schlesinger, according to which facts call for explanation when (...) they belong to extraordinary types. I compare the merits of this view to those of several alternatives and respond to a salient objection. I end with a discussion of how the theory fares when applied to cosmological fine-tuning arguments. (shrink)

Both Husserl and Sartre speak of quasi-presence in their descriptions of the lived experience of imagination, and for both philosophers, accounting for quasi-presence means developing an account of the hyle proper to imagination. Guided by the perspective of fulfillment, Husserl’s theory of imaginary quasi-presence goes through three stages. Having experimented first with a depiction-model and then a perception-model, Husserl’s mature theory appeals to his innovative conception of inner consciousness. This elegant account nevertheless fails to do justice to the facticity and (...) bodily involvement of our imaginary experience. Sartre’s theory of analogon, based on his conception of imaginary quasi-presence as ‘magical’ self-affection, embodies important insights on these issues. Kinesthetic sensations and feelings are the modes in which we make use of own body to possess and be possessed by the imaginary object, thus lending it a semblance of bodily presence. (shrink)

Evidentialism is the thesis that all reasons to believe p are evidence for p. Pragmatists hold that pragmatic considerations – incentives for believing – can also be reasons to believe. Nishi Shah, Thomas Kelly and others have argued for evidentialism on the grounds that incentives for belief fail a ‘reasoning constraint’ on reasons: roughly, reasons must be considerations we can reason from, but we cannot reason from incentives to belief. In the first half of the paper, I show that this (...) argument fails: the claim that we cannot reason from incentives is either false or does not combine with the reasoning constraint to support evidentialism. However, the failure of this argument suggests an alternative route to evidentialism. Roughly, reasons must be premises of good reasoning, but it is not good reasoning to reason from incentives to belief. The second half of the paper develops and defends this argument for evidentialism. (shrink)

Intuitively, there is a difference between knowledge and mere belief. Contemporary philosophical work on the nature of this difference has focused on scenarios known as “Gettier cases.” Designed as counterexamples to the classical theory that knowledge is justified true belief, these cases feature agents who arrive at true beliefs in ways which seem reasonable or justified, while nevertheless seeming to lack knowledge. Prior empirical investigation of these cases has raised questions about whether lay people generally share philosophers’ intuitions about these (...) cases, or whether lay intuitions vary depending on individual factors (e.g. ethnicity) or factors related to specific types of Gettier cases (e.g. cases that include apparent evidence). We report an experiment on lay attributions of knowledge and justification for a wide range of Gettier Cases and for a related class of controversial cases known as Skeptical Pressure cases, which are also thought by philosophers to elicit intuitive denials of knowledge. Although participants rated true beliefs in Gettier and Skeptical Pressure cases as being justified, they were significantly less likely to attribute knowledge for these cases than for matched true belief cases. This pattern of response was consistent across different variations of Gettier cases and did not vary by ethnicity or gender, although attributions of justification were found to be positively related to measures of empathy. These findings therefore suggest that across demographic groups, laypeople share similar epistemic concepts with philosophers, recognizing a difference between knowledge and justified true belief.

A particularly important, pressing, philosophical question concerns whether Confederate monuments ought to be removed. More precisely, one may wonder whether a certain group, viz. the relevant government officials and members of the public who together can remove the Confederate monuments, are morally obligated to (of their own volition) remove them. Unfortunately, academic philosophers have largely ignored this question. This paper aims to help rectify this oversight by moral philosophers. In it, I argue that people have a moral obligation to remove (...) most, if not all, public Confederate monuments because of the unavoidable harm they inflict on undeserving persons. In the first section, I provide some relevant historical context. In the second section, I make my unique harm-based argument for the removal of Confederate monuments. In the third section, I consider and rebut five objections. (shrink)

The Significance Argument (SA) for the irreducibility of consciousness is based on a series of new puzzle-cases that I call multiple candidate cases. In these cases, there is a multiplicity of physical-functional properties or relations that are candidates to be identified with the sensible qualities and our consciousness of them, where those candidates are not significantly different. I will argue that these cases show that reductive materialists cannot accommodate the various ways in which consciousness is significant and must allow massive (...) vagueness in conscious experience. I also will argue that a nonreductive theory of the conscious-of relation can easily provide a very satisfying, unified explanation of the ways in which this relation is significant. (shrink)
