Are the real numbers rich enough to measure intelligence? We generalize a result of Alexander and Hutter about the so-called Legg-Hutter intelligence measures of reinforcement learning agents. Using the generalized result, we exhibit a paradox: in one particular version of the Legg-Hutter intelligence measure, certain agents all have intelligence 0, even though in a certain sense some of them outperform others. We show that this paradox disappears if we vary the Legg-Hutter intelligence measure to be hyperreal-valued rather than real-valued.

The Molyneux question asks: would a blind person, who knows spheres and cubes only from touch, be able to recognize these shapes visually immediately upon becoming sighted, without touching them? Molyneux himself answered no. Locke accepted Molyneux’s negative answer. But Locke’s answer appears inconsistent with the doctrine of common sensibles, according to which some ideas are given in more than one sense modality. Motivated by alleviating this tension, philosophers have put forth several interpretations of Locke’s views on shape perception. Here (...) I motivate a novel interpretation of Locke that can better resolve the tension. (shrink)

Conventional wisdom has it that truth is always evaluated using our actual linguistic conventions, even when considering counterfactual scenarios in which different conventions are adopted. This principle has been invoked in a number of philosophical arguments, including Kripke’s defense of the necessity of identity and Lewy’s objection to modal conventionalism. But it is false. It fails in the presence of what Einheuser (2006) calls c-monsters, or convention-shifting expressions (on analogy with Kaplan’s monsters, or context-shifting expressions). We show that c-monsters naturally (...) arise in contexts, such as metalinguistic negotiations, where speakers entertain alternative conventions. We develop an expressivist theory—inspired by Barker (2002) and MacFarlane (2016) on vague predications and Einheuser (2006) on counterconventionals—to model these shifts in convention. Using this framework, we reassess the philosophical arguments that invoked the conventional wisdom. (shrink)

The recent literature abounds with accounts of the semantics and pragmatics of so-called predicates of personal taste, i.e. predicates whose application is, in some sense or other, a subjective matter. Relativism and contextualism are the major types of theories. One crucial difference between these theories concerns how we should assess previous taste claims. Relativism predicts that we should assess them in the light of the taste standard governing the context of assessment. Contextualism predicts that we should assess them in the (...) light of the taste standard governing the context of use. We show in a range of experiments that neither prediction is correct. People have no clear preferences either way and which taste standard they choose in evaluating a previous taste claim crucially depends on whether they start out with a favorable attitude towards the object in question and then come to have an unfavorable attitude or vice versa. We suggest an account of the data in terms of what we call hybrid relativism. (shrink)

The late tenth century siddha and scholar Ratnākaraśānti, also known as the Mahāsiddha Śāntipa, was renowned as the author of both philosophical śāstras and commentaries on tantra. Typically, these are considered separate spheres of activity. However, Ratnākaraśānti’s approach, building on the tradition of scholarship associated with the Mahāvairocanābhisaṃbodhitantra and the Guhyasamājatantra, as well as on Yogācāra analysis and Buddhist pramāṇa theory, is highly syncretic. This paper is a study of Ratnākaraśānti’s commentaries that highlights his synthesis of the exoteric and esoteric (...) streams of Buddhist discourse, with particular emphasis on the nondual nature of reflexive awareness (svasaṃvitti, rang rig), or 'luminosity' (prakāśa, gsal ba), which serves as the conceptual bridge between sūtra and tantra.

Kant’s accounts of the Highest Good and the moral argument for God and immortality are central features of his philosophy. But both involve lingering puzzles. In this entry, we first explore what the Highest Good is for Kant and the role it plays in a complete account of ethical life. We then focus on whether the Highest Good involves individuals only, or whether it also connects with Kant’s doctrines about the moral progress of the species. In conclusion, we look into (...) three ways of articulating the moral argument for God and immorality that take our commitment to the Highest Good as their point of departure. (shrink)

In this paper, we analyse how GPS-based navigation systems are transforming some of our intellectual virtues and then suggest two strategies to improve our practices regarding the use of such epistemic tools. We start by outlining the two main approaches in virtue epistemology, namely virtue reliabilism and virtue responsibilism. We then discuss how navigation systems can undermine five epistemic virtues, namely memory, perception, attention, intellectual autonomy, and intellectual carefulness. We end by considering two possible interlinked ways of trying to remedy (...) this situation: [i] redesigning the epistemic tool to improve the epistemic virtues of memory, perception, and attention; and [ii] the cultivation of cognitive diligence for wayfinding tasks scaffolding intellectual autonomy and carefulness.

In chapter 3 of Wittgenstein on Rules and Private Language, Kripke’s Wittgenstein offers a “sceptical solution" to the sceptical paradox about meaning developed in chapter 2 (according to which there are no facts in virtue of which ascriptions of meaning such as “Jones means addition by ‘+’” can be true). Although many commentators have taken the sceptical solution to be broadly analogous to non-factualist theories in other domains, such as non-cognitivism or expressivism in metaethics, the nature of the sceptical solution (...) has not been well-understood. The main aim of this paper is to advance our understanding of the nature of the non-factualism about meaning proposed in the sceptical solution. It attempts to outline some desiderata that should be respected by interpretations of the sceptical solution and considers two objections raised against it in Barry Stroud’s paper “Wittgenstein on Meaning, Understanding and Community". It attempts to correct misconstruals of the sceptical solution that have been promulgated by Davidson and some of his followers and suggests that the sceptical solution developed by Kripke’s Wittgenstein is best viewed as a form of quasi-realism about meaning. It ends by outlining what it takes to be the most pressing challenges facing the sceptical solution. (shrink)

Achieving space situational awareness requires, at a minimum, the identification, characterization, and tracking of space objects. Leveraging the resultant space object data for purposes such as hostile threat assessment, object identification, and conjunction assessment presents major challenges. This is in part because in characterizing space objects we reference a variety of identifiers, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, operational processes, operational statuses, and so forth, which tend to be defined in highly heterogeneous and sometimes inconsistent (...) ways. The Space Domain Ontologies are designed to provide a consensus-based realist framework for formulating such characterizations in a way that is both consistent and computable. Space object data are aligned with classes and relations in a suite of ontologies built around the existing Space Object Ontology. They are stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space situational awareness and the needs of spacecraft operators and analysts. This paper provides an overview of the Space Domain Ontologies and their development and use. It presents the motivation for and advantages of the Space Domain Ontologies, including the benefits they provide for enhancing and maintaining long-term space situational awareness. (shrink)

The modern Everett interpretation of quantum mechanics describes an emergent multiverse. The goal of this paper is to provide a perspicuous characterisation of how the multiverse emerges making use of a recent account of (weak) ontological emergence. This will be cashed out with a case study that identifies decoherence as the mechanism for emergence. The greater metaphysical clarity enables the rebuttal of critiques due to Baker (2007) and Dawid and Th\'ebault (2015) that cast the emergent multiverse ontology as incoherent; responses (...) are also offered to challenges to the Everettian approach from Maudlin (2010) and Monton (2013).

This paper presents a novel understanding of the notion of calculability. In Gricean frameworks, calculability is defined in terms of how speakers can infer an implicature. The relevant inferences must e.g. be based on maxims of conversation or cooperation principles. Meanwhile, I suggest to define calculability in terms of when, or under which conditions, speakers can infer an implicature. An implicature is calculable if hearers can infer its existence even supposing that the implicature is not semantically encoded. This approach avoids (...) familiar challenges, including recently prominent challenges from pragmatic particularism. (shrink)

Skeptical invariantists maintain that the expression “knows” invariably expresses an epistemically extremely demanding relation. This leads to an immediate challenge. The knowledge relation will hardly if ever be satisfied. Consequently, we can rarely if ever apply “knows” truly. The present paper assesses a prominent strategy for skeptical invariantists to respond to this challenge, which appeals to loose talk. Based on recent developments in the theory of loose talk, I argue that such appeals to loose talk fail. I go on to (...) present a closely related, more promising response strategy, which combines assumptions about the dynamics of pragmatic presuppostions from Blome-Tillmann (2014) with an appeal to conversational exculpature, a phenomenon recently studied by Hoek (2018, 2019).

Can there be grounding without necessitation? Can a fact obtain wholly in virtue of metaphysically more fundamental facts, even though there are possible worlds at which the latter facts obtain but not the former? It is an orthodoxy in recent literature about the nature of grounding, and in first-order philosophical disputes about what grounds what, that the answer is no. I will argue that the correct answer is yes. I present two novel arguments against grounding necessitarianism, and show that grounding (...) contingentism is fully compatible with the various explanatory roles that grounding is widely thought to play.

In 1937 Joan Robinson proposed that “when capitalism is rightly understood, the rate of interest will be set at zero and the major evils of capitalism will disappear”. A permanent zero rate would abolish capitalist profit except in limited cases, leaving nearly all output to be claimed by labour as wages. It would allow capital to be allocated on the basis of prospective social benefit rather than short-term profitability and a collateral basis that favours the wealthy. It would remove some (...) of the economic pressure to use resources unsustainably. So why not do this? I argue that the few available philosophical arguments for positive interest rates are unsatisfactory. Those who want a just and sustainable form of capitalism should target net zero for the interest rate. (shrink)

A supplemental document for "Metalinguistic Gradability".

In the Critique of Pure Reason, Kant states that ideas give us the rule for organizing experience and ideals serve as archetypes or standards against which one can measure copies. Further, he states that ideas and ideals can be practical. Understanding how precisely these concepts should function presents a challenging and understudied philosophical puzzle. I offer a reconstruction of how ideas and ideals might be practical in order to uphold, to my mind, a conceptually worthy distinction. A practical idea, I (...) argue, is best understood as a reference to the categorical imperative (and its various formulations), which guides conduct directly as a rule. A practical ideal, by contrast, I think is a substrate that serves two functions: one that (a) helps us gauge moral deficiencies and another that (b) reveals the potential for moral improvement. In response to well-grounded sceptical concerns, I argue that ideals are indirectly practical in that they ground the possibility to recognise moral states of affairs and be moral in the first place.

Thomas Schmidt argues that a widely held combination of views about reasons and ought—the Balancing View of Ought and the claim that reasons against Q are reasons for not-Q—is extensionally adequate only if it is complemented by two principles of reasons transmission. In this paper I present three problems for Schmidt’s package of views and two problems for his transmission principles considered in isolation. I then defend a rival package of views—a version of the Balancing View and the claim that (...) reasons against Q are reasons that bear on Q with negative weight—that avoids these problems and secures extensional adequacy without Schmidt’s principles. I conclude that friends of the Balancing View should prefer my package of views. (shrink)

There are many different ways to talk about the world. Some ways of talking are more expressive than others—that is, they enable us to say more things about the world. But what exactly does this mean? When is one language able to express more about the world than another? In my dissertation, I systematically investigate different ways of answering this question and develop a formal theory of expressive power, translation, and notational variance. In doing so, I show how these investigations (...) help to clarify the role that expressive power plays within debates in metaphysics, logic, and the philosophy of language. (shrink)

Dieser Beitrag setzt sich mit der unterrichtspraktischen Frage nach der Einführung und Vertiefung von Begriffsverständnissen im Philosophie- und Ethikunterricht auseinander. Als Ausgangspunkt dient dazu Sistermanns Bonbonmodell. Es wird dafür argumentiert, dass dieses Modell sowie die Leitidee der Problemorientierung erweitert werden sollten, so man dem Anspruch einer Vermittlung tiefgehender Begriffsverständnisse gerecht werden will. Um eine solche Erweiterung vorzuschlagen, werden erstens ein lernproduktorientiertes Lehr-Lern-Modell aus der Physikdidaktik und zweitens lernpsychologische Grundlagen, die als Darstellungsebenenwechsel in der Mathematikdidaktik Anwendung finden, hinzugezogen.

I argue that embodied understanding and conceptual-representational understanding interact through schematic structure. I demonstrate that common conceptions of these two kinds of understanding, such as developed by Wheeler (2005, 2008) and Dreyfus (2007a, b, 2013), entail a separation between them that gives rise to significant problems. Notably, it becomes unclear how they could interact; a problem that has been pointed out by Dreyfus (2007a, b, 2013) and McDowell (2007) in particular. I propose a Kantian strategy to close the gap between (...) them. I argue that embodied and conceptual-representational understanding are governed by schemata. Since they are governed by schemata, they can interact through a structure that they have in common. Finally, I spell out two different ways to conceive of the schematic interaction between them—a close, grounding relationship and a looser relationship that allows for a minimal interaction, but preserves the autonomy of both forms of understanding.

I propose an approach to liar and Curry paradoxes inspired by the work of Roger Swyneshed in his treatise on insolubles (1330-1335). The keystone of the account is the idea that liar sentences and their ilk are false (and only false) and that the so-called ''capture'' direction of the T-schema should be restricted. The proposed account retains what I take to be the attractive features of Swyneshed's approach without leading to some worrying consequences Swyneshed accepts. The approach and the resulting (...) logic (called ''Swynish Logic'') are non-classical, but are consistent and compatible with many elements of the classical picture including modus ponens, modus tollens, and double-negation elimination and introduction. It is also compatible with bivalence and contravalence. My approach to these paradoxes is also immune to an important kind of revenge challenge that plagues some of its rivals. (shrink)

Many of my first students at Anzaldúa’s alma mater read Borderlands/La Frontera and concluded that Anzaldúa was not a philosopher. Hostile comments suggested that Anzaldúa’s intimately personal and poetic ways of writing were not philosophical. In response, I created “American Philosophy and Self-Culture” using backwards course design and taught variations of it in 2013, 2016, and 2018. Students spend nearly a month exploring Anzaldúa’s works, but only after reading three centuries of U.S.-American philosophers who wrote in deeply personal and literary (...) ways about self-transformation, community-building, and world-changing. The sections of this chapter: 1) describe why my first students rejected Anzaldúa as a philosopher in terms of the discipline’s parochialism; 2) present Anzaldúa’s broader understanding of herself as a philosopher; 3) summarize my reconstructed Anzaldúa-inspired American Philosophy course and outline some assignments; 4) discuss how my students respond to Borderlands/La Frontera when we read it through the lens of self-culture; and 5) explain my attempt to shape the subdiscipline of American Philosophy by teaching Anzaldúa to specialists at the 2017 Summer Institute in American Philosophy.

Recently, Yudkowsky and Soares (2018) and Levinstein and Soares (2020) have developed a novel decision theory, Functional Decision Theory (FDT). They claim FDT outperforms both Evidential Decision Theory (EDT) and Causal Decision Theory (CDT). Yet FDT faces several challenges. First, it yields some very counterintuitive results (Schwarz 2018; MacAskill 2019). Second, it requires a theory of counterpossibles, for which even Yudkowsky and Soares (2018) and Levinstein and Soares (2020) admit we lack a “full” or “satisfactory” account. Here, I focus on (...) the latter problem of counterpossibles. My aim is to establish two claims. First, the problem of counterpossibles does not even arise without a fairly strong assumptionone that rarely applies to human agents, but may apply to artificial agents. And second, even given this assumption, the problem is solvable, though how best to solve it remains an open question. (shrink)

In the history of philosophy, the distinction between positive and negative predication has been collapsed. The collapse has caused us to search for a way through Parmenides’ gate: we have constructed scaffolding to see over its boundaries. Kant gave us the distinction between conceptual and non-conceptual knowledge; Hegel gave us determinate negation; Frege gave us the negation stroke; Husserl gave us bracketing and disappointment; G. Spencer-Brown gave us a calculus of distinction. Despite this, we find ourselves—alongside Wittgenstein— wondering how it (...) can be the case that we are able to think what is not the case. We are puzzled by the fact that we can think nothing without the thought lacking content. I suggest that this confusion is unnecessary. Throughout this work, I exercise the thought that the distinction between positive and negative predication is mistaken. I rather suggest that to think what is or is not the case necessarily depends upon an exemplar distinction that is experientially recognized and learned in the world. All the same, our capacity to understand natural distinction likewise depends upon our practical and pervasively conceptual capacities to express it in language. I conclude by suggesting that what makes positive and negative predication distinct is a fundamental unity in conceptual form through its capacity to play distinct functional roles in linguistic practice.

Contrary to the popular assumption that linguistically mediated social practices constitute the normativity of action (Kiverstein and Rietveld, 2015; Rietveld, 2008a,b; Rietveld and Kiverstein, 2014), I argue that it is affective care for oneself and others that primarily constitutes this kind of normativity. I argue for my claim in two steps. First, using the method of cases I demonstrate that care accounts for the normativity of action, whereas social practices do not. Second, I show that a social practice account of (...) the normativity of action has unwillingly authoritarian consequences in the sense that humans act only normatively if they follow social rules. I suggest that these authoritarian consequences are the result of an uncritical phenomenology of action and the fuzzy use of “normative”. Accounting for the normativity of action with care entails a realistic picture of the struggle between what one cares for and often repressive social rules. (shrink)

Our paper examines Gloria Anzaldúa’s critical appropriation of Mexican philosophical sources, especially in the writing of Borderlands/La Frontera. We demonstrate how Anzaldúa developed a transnational Philosophy of Mexicanness, effectively contributing to what has been recently characterized as the “multi-generational project to pursue philosophy from and about Mexican circumstances” (Vargas). More specifically, we recover “La Mexicana en la Chicana” by paying careful attention to Anzaldúa’s Mexican sources, both those she explicitly cites and those we have discovered while conducting archival research using (...) the Gloria Evangelina Anzaldúa Papers from the Benson Latin American Collection at the University of Texas at Austin. The three sections of our paper: 1) define the terms Mexican and philosophy in conversation with Anzaldúa’s work, 2) examine the Mexican philosophical sources that Anzaldúa cites in Borderlands/La Frontera, and 3) present the other major Mexican philosophical influences on Anzaldúa that we have found in her archive. The eight Mexican philosophical sources we discuss here include: José Vasconcelos (1882-1959), Miguel León-Portilla (1926-2019), Juana Armanda Alegría (1938- ), Octavio Paz (1914-1998), Samuel Ramos (1897-1959), Rosario Castellanos (1925-1974), Sor Juana Inés de La Cruz (1648-1695), and Jorge Carrión (1913-2005).

The starting point of this article is the didactic question of the relationship between conceptual knowledge and competencies in the education of philosophy and ethics. Against the background of the philosophical debate on the conception of concepts, a conception of concepts as abilities is outlined. With this conception, in a first step, the disjunction between conceptual knowledge on the one hand and competencies on the other hand is dissolved. In a second step, a learningtheoretical framework of the formation of philosophical (...) concepts is developed through a critical examination of the so-called conceptual change. As a result, critical elucidation of concepts presents itself as a fundamental goal of ethics and philosophy teaching. (shrink)

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)

What happens when scholars come together to study Buddhist and German Idealist perspectives on mind and representation? We explore this question and reflect on methodological considerations in what is often referred to as "comparative philosophy.".

Discussion of the relevance of grounding to substantiveness, theory-choice, and “location problems” in metaphysics.

Does natural science give us reason to believe that mathematical statements are true? And does natural science give us reason to believe in some particular metaphysics of mathematics? These two questions should be firmly distinguished. My argument in this chapter is that a negative answer to the second question is compatible with an affirmative answer to the first. Loosely put, even if science settles the truth of mathematics, it does not settle its metaphysics.

What function does the highest good serve in our thinking and doing? I propose a new interpretation that sees its importance as fulfilling a contemplative need to construct a worldview.

Dieses Buch bietet eine grundlegende Einführung in den Einsatz der Methode des Decision Theater zur Vermittlung von mathematischer Modellierungskompetenz im Schulkontext. In den letzten Jahren hat sich unter anderem anhand der Covid-19 Pandemie mehr denn je gezeigt, wie Mathematik im Allgemeinen und das mathematische Modellieren im Speziellen zum Verständnis globaler Herausforderungen und Möglichkeiten zu ihrer Bewältigung beiträgt. Deshalb sollte die mathematische Modellierungskompetenz eine zentrale Rolle im Schulunterricht spielen. Doch der Prozess von Vermittlung und Erwerb einer solchen Kompetenz ist komplex und (...) mit vielfältigen Schwierigkeiten verbunden. Angesichts dieser Ausgangslage stellt das Buch die Methode des Decision Theater als innovative Lernumgebung neuer Art vor, die die Vermittlung von mathematischer Modellierungskompetenz unterstützen kann. Dabei trägt die Methode des Decision Theatre auf drei Ebenen dazu beiträgt, Modellierungskompetenz und ein damit verbundenes ganzheitliches Bild der Mathematik zu fördern: Das Decision Theatre dient als IT-Dienstleister, als Wissenschaftskommunikator und als interaktiv-diskursive Lernumgebung. Neben Geschichte und Definition des Decision Theater, stellt das Buch dessen Einsatz konkret am Beispiel des Projekts „Schule @ Decision Theatre Lab“ des Berliner Exzellenzclusters MATH+ Berlin Mathematics Research Center vor. Als Zusammenfassung der wichtigsten Aspekte des Einsatzes der Methode des Decision Theater im Schulkontext richtet sich das Buch an Didaktiker*innen und Lehrkräfte aller Schulformen. (shrink)

Individualist subjectivism is a position in metaethics which states that moral claims are descriptions of attitudes, e.g. 'murder is wrong' means 'I disapprove of murder'. In this short article I present a novel argument against it by appealing to the conversion between first-person and third-person claims. I argue that individualist subjectivism, and more broadly, any propositions which refer to the self without a word like 'I' or me', fail to account for the fact that person with the name X saying (...) 'I' could be rephrased as anybody saying 'X', a process I call 'personalisation'. (shrink)

While most literature on Maimonides’ Guide for the Perplexed is written by professional scholars, most readers of the treatise are “laymen”. The perspective of a reader from the latter category is typically different from that of the former. This division was expected by the author: the Guide addresses multiple categories of readers. Traditionally the Guide is considered either as a philosophical text or as exegesis of difficult places in Scripture. My claim is that between long passages devoted to philosophy and (...) interpretation of the Bible are interwoven short remarks of very different kind: aimed straight at the emotional center of a reader. These remarks are supposed to take a reader out of region of comfort and invoke strong emotional responses. Examples of such passages are given and discussed. On the basis of these examples I suggest that Maimonides (roughly) divided educational development of a potential reader into three levels and the main educational purpose of the straightforward reading of the Guide in this context was the progression of a reader from level 1 to level 2, while “accomplished” individuals of level 3 are addressed by hints. This educational method of Maimonides is criticized. (shrink)

Joint attention is a social-cognitive phenomenon in which two or more agents direct their attention together towards the same object. Definitions range from this rather broad conception to more specific definitions which require that, in addition, attention be directed to the same aspect of that object and that agents need to be mutually aware of their jointly attending. Joint attention is an important coordination mechanism in joint action. The capacity for engaging in joint attention, in particular in the sense of (...) this narrower definition, is frequently taken to indicate the presence of theory of mind in the participating agents, and is also implicated in the development of theory of mind. However, the prominence of sensorimotor components in establishing and sustaining episodes of joint attention — e.g., eye and head movements, pointing and vocalizations — suggests that sensorimotor approaches to social interaction may be well-placed to account for important parts of joint attention without invoking theory-of-mind abilities, and may therefore provide a valuable alternative to approaches emphasizing theory of mind. In particular, sensorimotor accounts may explain aspects of joint attention through the dynamics and regularities in the sensorimotor processes that coordinate the activities of the agents. (shrink)

Some intentional attitudes (beliefs, fears, desires, etc.) have a common focus in spite of there being no object at that focus. For example, two beliefs may be about the same witch even when there are no witches, different astronomers had beliefs directed at Vulcan, even though there is no such planet. This relation of having a common focus, whether or not there is an actual concrete object at that focus, is called intentional identity. In the first part of this thesis (...) I develop a new theory of intentional identity, the triangulation theory, and argue that it has significant advantages over the extant theories of intentional identity in the literature. Empty attitudes (attitudes that are not, prima facie, about anything that exists) will serve as useful cases for testing theories of intentional identity. -/- In the second part, I put the theory developed in the first part to work. I use triangulation theoretic tools to shed light on other debates about intentional attitudes. Some issues to which intentional identity are relevant are the debate about the content of intentional attitudes, the issue of whether or not we need to appeal to external constraints on the content of intentional attitudes, how we should understand the agreement and disagreement of attitudes, how we should construe communication and how we ought to solve Kripke’s puzzle about belief. The second part of this thesis also motivates a broadly internalist and individualistic approach to the con-tent of intentional attitudes; it turns out that if we take a closer look at the narrowly construed psychological states of agents we find materials that allow us to make sense of phenomena usually associated with externalist constraints on the content of attitudes (such as causal constraints and eligibility constraints) in a new way.

Wie kann es gelingen, dem wissenschaftlichen Streben in der Psychologie eine Ordnung zu geben? In dem Buch werden zwei Perspektiven eingenommen: Zunächst blickt die Philosophie auf die Möglichkeit einer theoretischen Psychologie in Hinsicht auf anthropologische und wissenschaftstheoretische Voraussetzungen, dann die Experimentalpsychologie auf die Möglichkeit guter Theoriebildung. Der dritte Teil des Buches ist der Versuch einer Synthese, in dem der philosophisch-psychologische Perspektivenpluralismus als Programm vorgeschlagen wird, die Richtungen, in die der Fortschritt der Disziplin erfolgt, kritisch zu begleiten.

This dissertation examines the theory of perceptual cognition laid out by the 7th century Buddhist scholar, Dharmakīrti, in his magnum opus, the Pramāṇavārttika. Like most theories of perception, both ancient and modern, the sensory cognition of ordinary objects is a topic of primary concern. Unlike other theorists, however, Dharmakīrti advances a technical definition of “perception” as a cognition which is both nonconceptual and non-erroneous. Dharmakīrti’s definition of perception is thereby deliberately inclusive of three additional types of “perceptual” cognition, in addition (...) to veridical sensory awareness: the nonconceptual mental apprehension of an immediately-preceding cognition (“mental perception”), the vivid appearance of soteriologically efficacious objects of contemplative practice (“yogic perception”), and the sheer unmediated presence of the contents of cognition—whatever these might be—to the cognizing mind (“reflexive awareness”). Through the logical examination of what it means to be aware of an object, Dharmakīrti demonstrates that the awareness of an object is just the awareness of a phenomenal form or cognitive image produced by that object. Pursuing this analysis further, however, Dharmakīrti argues that the very notion of an object of cognition that exists “externally” or outside the mind is incoherent. Additionally, Dharmakīrti maintains that the phenomenological structure of subject and object—that is, the “first-personal” sense of one’s own cognitions as pertaining to oneself (“for-me-ness”), together with the inseparably concomitant sense that the objects of cognition exist “out there” in an extramental world—is strictly a form of cognitive error. Therefore, because ordinary sensory cognition is inherently structured by this subject-object duality, ordinary sensory cognition must in the final analysis be understood as erroneous. According to Dharmakīrti, in other words, ultimately only the nondual “luminosity” of reflexive awareness is genuinely perceptual, because only reflexive awareness is undistorted by nature. In this way, Dharmakīrti’s epistemology provides a theoretical foundation for the advanced nondual contemplative practices of Indian and Tibetan Buddhism, particularly Mahāmudrā and rDzogs chen.

The aim of this article is to give students a small sense of what metamathematics is—that is, how one might use mathematics to study mathematics itself. School or college teachers could base a classroom exercise on the letter games I shall describe and use them as a springboard for further exploration.

Nevertheless, they show, in (...) an accessible way, how metamathematics can be mathematically interesting. (shrink)

Isaiah Berlin famously attacked a view he called historical inevitability. He believed that a causal view of history entails the adoption of an extreme deterministic position – a kind of determinism which would rule out the possibility of free will, turning moral responsibility a notion void of meaning. His thesis was also based on the assumption that historians are not just chroniclers of the past but need to engage in moral judgments; therefore should determinism hold true of our world, our (...) moral language – and consequently much of our historical language – would need to undergo serious revision. In this brief article we look in some detail at the arguments offered by Berlin in support of his thesis and offer criticism. (shrink)
