Virtue epistemology is among the dominant influences in mainstream epistemology today. An important commitment of one strand of virtue epistemology – responsibilist virtue epistemology (e.g., Montmarquet 1993; Zagzebski 1996; Battaly 2006; Baehr 2011) – is that it must provide regulative normative guidance for good thinking. Recently, a number of virtue epistemologists (most notably Baehr, 2013) have held that virtue epistemology not only can provide regulative normative guidance, but moreover that we should reconceive the primary epistemic aim of all education as (...) the inculcation of the intellectual virtues. Baehr’s picture contrasts with another well-known position – that the primary aim of education is the promotion of critical thinking (Scheffler 1989; Siegel 1988; 1997; 2017). In this paper – that we hold makes a contribution to both philosophy of education and epistemology and, a fortiori, epistemology of education – we challenge this picture. We outline three criteria that any putative aim of education must meet and hold that it is the aim of critical thinking, rather than the aim of instilling intellectual virtue, that best meets these criteria. On this basis, we propose a new challenge for intellectual virtue epistemology, next to the well-known empirically-driven ‘situationist challenge’. What we call the ‘pedagogical challenge’ maintains that the intellectual virtues approach does not have available a suitably effective pedagogy to qualify the acquisition of intellectual virtue as the primary aim of education. This is because the pedagogic model of the intellectual virtues approach (borrowed largely from exemplarist thinking) is not properly action-guiding. Instead, we hold that, without much further development in virtue-based theory, logic and critical thinking must still play the primary role in the epistemology of education. (shrink)

I respond to P. J. Ivanhoe's criticisms of my translation of a key passage in Wang Yangming.

I argue that humans have moral relationships with dogs and cats that they could adopt, but do not. The obligations of those of us who refrain from incurring particular relationships with dogs and cats are correlative with the power of persons with what Jean Harvey calls “interactive power,” the power to take the initiative in and direct the course of a relationship. I connect Harvey’s points about interactive power to my application of Eva Kittay’s “dependency critique,” to show (...) that those of us who refrain from incurring particular relationships of dependency rely on caregivers in our communities and regions to fulfill the moral and social demands that an abundance of unowned companionable animals makes on the community.

Are transcendental phenomenology and possible worlds semantics, two seemingly disparate, perhaps even incompatible philosophical traditions, actually complementary? Have two well-known representatives of each tradition, J.N. Mohanty and J. Hintikka, misinterpreted the other's philosophical "program" in such a way that they did not recognize the complementarity? Charles Harvey 1 has recently argued that the answer to both questions is "yes." Here I intend to argue that the answer to the first is unclear, whereas the answer to the second is "no." (...) Mohanty (at least) rightly cites fundamental differences between transcendental phenomenology and possible worlds semantics. (shrink)

This paper discusses the Uniqueness Thesis, a core thesis in the epistemology of disagreement. After presenting uniqueness and clarifying relevant terms, a novel counterexample to the thesis will be introduced. This counterexample involves logical disagreement. Several objections to the counterexample are then considered, and it is argued that the best responses to the counterexample all undermine the initial motivation for uniqueness.

A key question in the philosophy of logic is how we have epistemic justification for claims about logical entailment (assuming we have such justification at all). Justification holism asserts that claims of logical entailment can only be justified in the context of an entire logical theory, e.g., classical, intuitionistic, paraconsistent, paracomplete etc. According to holism, claims of logical entailment cannot be atomistically justified as isolated statements, independently of theory choice. At present there is a developing interest in—and endorsement of—justification holism (...) due to the revival of an abductivist approach to the epistemology of logic. This paper presents an argument against holism by establishing a foundational entailment-sentence of deduction which is justified independently of theory choice and outside the context of a whole logical theory.

Philosophical accounts denying that temporal passage is an objective feature of reality face an explanatory challenge with respect to why it appears to us as though time passes. Recently, two solutions have surfaced. Cognitive illusionism claims that people experience the passage of time due to their belief that time passes. Cognitive error theory claims that we do not experience the passage of time, but hold the belief that we do, which we have acquired through making an inference from the prior (...) belief that time passes. These approaches suppose that belief and passage experience are explanatorily connected, and they depend on the claims that people who experience the passage of time or at least believe that they do also believe that time passes. To test these claims, we probed the beliefs of populations of individuals with depression and schizotypy, thus conditions that are strongly associated with alterations in temporal phenomenology. Depression was assessed with the Beck Depression Inventory (BDI) and schizotypy with the short Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE). While cognitive illusionism and inferentialist cognitive error theory would predict a strong association between BDI and O-LIFE scores and beliefs about time passage, our study found no such association. The experience of passage does not seem to be explanatorily connected to beliefs about the passage of time. (shrink)

The philosophical case for extended cognition is often made with reference to ‘extended-memory cases’ ; though, unfortunately, proponents of the hypothesis of extended cognition as well as their adversaries have failed to appreciate the kinds of epistemological problems extended-memory cases pose for mainstream thinking in the epistemology of memory. It is time to give these problems a closer look. Our plan is as follows: in §1, we argue that an epistemological theory remains compatible with HEC only if its epistemic assessments (...) do not violate what we call ‘the epistemic parity principle’. In §2, we show how the constraint of respecting the epistemic parity principle stands in what appears to be a prima facie intractable tension with mainstream thinking about cases of propositional memory. We then outline and evaluate in §3 several lines of response. (shrink)

While the epistemic significance of disagreement has been a popular topic in epistemology for at least a decade, little attention has been paid to logical disagreement. This monograph is meant as a remedy. The text starts with an extensive literature review of the epistemology of (peer) disagreement and sets the stage for an epistemological study of logical disagreement. The guiding thread for the rest of the work is then three distinct readings of the ambiguous term ‘logical disagreement’. Chapters 1 and (...) 2 focus on the Ad Hoc Reading according to which logical disagreements occur when two subjects take incompatible doxastic attitudes toward a specific proposition in or about logic. Chapter 2 presents a new counterexample to the widely discussed Uniqueness Thesis. Chapters 3 and 4 focus on the Theory Choice Reading of ‘logical disagreement’. According to this interpretation, logical disagreements occur at the level of entire logical theories rather than individual entailment-claims. Chapter 4 concerns a key question from the philosophy of logic, viz., how we have epistemic justification for claims about logical consequence. In Chapters 5 and 6 we turn to the Akrasia Reading. On this reading, logical disagreements occur when there is a mismatch between the deductive strength of one’s background logic and the logical theory one prefers (officially). Chapter 6 introduces logical akrasia by analogy to epistemic akrasia and presents a novel dilemma. Chapter 7 revisits the epistemology of peer disagreement and argues that the epistemic significance of central principles from the literature are at best deflated in the context of logical disagreement. The chapter also develops a simple formal model of deep disagreement in Default Logic, relating this to our general discussion of logical disagreement. The monograph ends in an epilogue with some reflections on the potential epistemic significance of convergence in logical theorizing. (shrink)

This paper discusses the uniqueness thesis, a core thesis in the epistemology of disagreement.

Default logic has been a very active research topic in artificial intelligence since the early 1980s, but has not received as much attention in the philosophical literature thus far. This paper shows one way in which the technical tools of artificial intelligence can be applied in contemporary epistemology by modeling a paradigmatic case of deep disagreement using default logic. In §1 model-building viewed as a kind of philosophical progress is briefly motivated, while §2 introduces the case of deep disagreement we (...) aim to model. On the heels of this, §3 defines our formal framework, viz., a refined Horty-style default logic. §4 then uses the framework to model deep disagreement, and finally §5 provides a critical discussion of the result.

The purpose of this essay is to offer support for the substance view of persons, the philosophical anthropology defended by Patrick Lee in his essay. In order to accomplish this the author presents a brief definition of the substance view; argues that the substance view has more explanatory power in accounting for why we believe that human persons are intrinsically valuable even when they are not functioning as such, why human persons remain identical to themselves over time, and why it (...) follows from these points that the unborn are human persons; and responds to two arguments that attempt to establish the claim that the early human being is not a unified substance until at least fourteen days after conception.

In order to improve our understanding of the components that reflect functionally important processes during reward anticipation and consumption, we used principle components analyses (PCA) to separate and quantify averaged ERP data obtained from each stage of a modified monetary incentive delay (MID) task. Although a small number of recent ERP studies have reported that reward and loss cues potentiate ERPs during anticipation, action preparation, and consummatory stages of reward processing, these findings are inconsistent due to temporal and spatial overlap (...) between the relevant electrophysiological components. Our results show three components following cue presentation are sensitive to incentive cues (N1, P3a, P3b). In contrast to previous research, reward‐related enhancement occurred only in the P3b, with earlier components more sensitive to break‐even and loss cues. During feedback anticipation, we observed a lateralized centroparietal negativity that was sensitive to response hand but not cue type. We also show that use of PCA on ERPs reflecting reward consumption successfully separates the reward positivity from the independently modulated feedback‐P3. Last, we observe for the first time a new reward consumption component: a late negativity distributed over the left frontal pole. This component appears to be sensitive to response hand, especially in the context of monetary gain. These results illustrate that the time course and sensitivities of electrophysiological activity that follows incentive cues do not follow a simple heuristic in which reward incentive cues produce enhanced activity at all stages and substages.

We uncover a largely unnoticed and unaddressed problem in conservation research: arguments built within studies are sometimes defective in more fundamental and specific ways than appreciated, because they misrelate values and empirical matters. We call this the unraveled rope problem because just as strands of rope must be properly and intricately wound with each other so the rope supports its load, empirical aspects and value aspects of an argument must be related intricately and properly if the argument is to objectively (...) support its conclusion. By characterizing this problem with precision, our study differs from but complements existing studies of value issues in conservation science, in two ways. First, it focuses on key relationships between empirical issues and value issues, relations that have sometimes been obscured by focusing on these issues more independently of each other. Second, it focuses on these relationships within arguments and deploys a method of argument analysis and evaluation honed in other fields but under-utilized in conservation science. By combining our study's novel features, we detail six families of argument defect that exemplify the unraveled rope problem within existing literature. These defects sometimes manifest within basic research stages, rather than just in more applied downstream stages where roles for values are already obvious to many. As scientific reasoning and communication become increasingly important for addressing society's greatest environmental challenges, overcoming the unraveled rope problem will be essential to the success and integrity of conservation research. Therefore, we also outline potential solutions, preventative measures, and useful further work for conservation researchers. (shrink)

This paper aims to show that Selim Berker’s widely discussed prime number case is merely an instance of the well-known generality problem for process reliabilism and thus arguably not as interesting a case as one might have thought. Initially, Berker’s case is introduced and interpreted. Then the most recent response to the case from the literature is presented. Eventually, it is argued that Berker’s case is nothing but a straightforward consequence of the generality problem, i.e., the problematic aspect of the (...) case for process reliabilism (if any) is already captured by the generality problem.

One challenge to the rationality of religious commitment has it that faith is unreasonable because it involves believing on insufficient evidence. However, this challenge and influential attempts to reply depend on assumptions about what it is to have faith that are open to question. I distinguish between three conceptions of faith each of which can claim some plausible grounding in the Judaeo-Christian tradition. Questions about the rationality or justification of religious commitment and the extent of compatibility with doubt look different (...) on accounts of faith in which trust or hope, rather than belief, are the primary basis for the commitments. On such accounts, while the person of faith has a stake in the truth of the content, practical as well as epistemic considerations can legitimately figure in normative appraisals. Trust and hope can be appropriate in situations of recognized risk, need not involve self-deception, and are compatible with the idea that one's purely epistemic opinions should be responsive only to evidence.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

This paper introduces the axiom of Negative Dominance, stating that if a lottery f is strictly preferred to a lottery g, then some outcome in the support of f is strictly preferred to some outcome in the support of g. It is shown that if preferences are incomplete on a sufficiently rich domain, then this plausible axiom, which holds for complete preferences, is incompatible with an array of otherwise plausible axioms for choice under uncertainty. In particular, in this setting, Negative (...) Dominance conflicts with the standard Independence axiom. A novel theory, which includes Negative Dominance, and rejects Independence, is developed and shown to be consistent. (shrink)

I respond to the insightful comments of L iu Liangjian, Stephen Angle, and Trenton Wilson.

Since the human genome was decoded, great emphasis has been placed on the unique, personal nature of the genome, along with the benefits that personalized medicine can bring to individuals and the importance of safeguarding genetic privacy. As a result, an equally important aspect of the human genome – its common nature – has been underappreciated and underrepresented in the ethics literature and policy dialogue surrounding genetics and genomics. This article will argue that, just as the personal nature of the (...) genome has been used to reinforce individual rights and justify important privacy protections, so too the common nature of the genome can be employed to support protections of the genome at a population level and policies designed to promote the public's wellbeing. In order for public health officials to have the authority to develop genetics policies for the sake of the public good, the genome must have not only a common, but also a public, dimension. This article contends that DNA carries a public dimension through the use of two conceptual frameworks: the common heritage framework and the common resource framework. Both frameworks establish a public interest in the human genome, but the CH framework can be used to justify policies aimed at preserving and protecting the genome, while the CR framework can be employed to justify policies for utilizing the genome for the public benefit. A variety of possible policy implications are discussed, with special attention paid to the use of large-scale genomics databases for public health research. (shrink)

Among philosophers, Fregeanism and sententialism are widely considered two of the leading theories of the semantics of attitude reports. Among linguists, these approaches have received little recent sustained discussion. This paper aims to bridge this divide. I present a new formal implementation of Fregeanism and sententialism, with the goal of showing that these theories can be developed in sufficient detail and concreteness to be serious competitors to the theories which are more popular among semanticists. I develop a modern treatment of (...) quantifying in for Fregeanism and sententialism, in the style of Heim and Kratzer, and then show how these theories can—somewhat surprisingly—account for “third readings” on the model of the “Standard Solution” from possible-worlds semantics. The resulting Fregean/sententialist proposal has a distinctive attraction: it treats data related to counterfactual attitudes —which have proven challenging to accommodate in the setting of possible worlds semantics—straightforwardly as third readings.

The article describes the seven characteristics that should identify a Jesuit university nowadays: 1) Pedagogical practices at Jesuit universities should promote authentic dialog and reconciliation; 2) Pedagogical practices at Jesuit universities should promote human excellence in every aspect of human life; 3) Pedagogical practices at Jesuit universities should promote exploration and discovery focused on and among disciplines; 4) Programs and practices at Jesuit universities should promote exploration and intercultural appreciation; 5) Jesuit universities should contribute both in theory and in practice (...) to the promotion of justice in society as a whole and within society’s various institutions; 6) A Jesuit classroom should promote the construction of a global vision in students and professors; and 7) Internships and programs at Jesuit universities should promote authentic spiritual growth and faith development. Based on the key approaches of the Ignatian Pedagogical Paradigm (ipp) and having in view that this is not a prefabricated model ready to be applied, its particularities in higher education are contextualized in light of the reflections of the Society General Superiors. The characteristics or identifiers presented motivate educational institutions to build an identity that responds to a long tradition of Jesuit education and a constant renewal of their commitment to form leaders to heal a broken world.

Liberalism has a complicated and sometimes uneasy relationship with truth. On one hand, liberalism requires that truth be widely valued and widely shared. It demands that governments be truthful and that citizens have ready access to numerous truths. Some liberals even take facilitating the discovery and dissemination of truth to be part of the raison d’être of liberal institutions. On the other hand, liberalism is averse to proclaiming or enforcing truth. It detaches truth from political legitimacy and deems certain truths (...) unfit to serve as bases of government. Some liberals have even suggested that liberal theory must work “without the concept of truth.” How has liberalism come to both demand truth and eschew it? This introductory section provides the beginnings of an answer by surveying some of the origins and core elements of liberal thought. (shrink)

I present a new puzzle about choice under uncertainty for agents whose preferences are sensitive to multiple dimensions of outcomes in such a way as to be incomplete. In response, I develop a new theory of choice under uncertainty for incomplete preferences. I connect the puzzle to central questions in epistemology about the nature of rational requirements, and ask whether it shows that preferences are rationally required to be complete.

In the law of rape, consent has been and remains a gendered concept. Consent presumes female acquiescence to male sexual initiation. It presumes a man desires to penetrate a woman sexually. It presumes the woman willingly yields to the man's desires. It does not presume, and of course does not require, female sexual desire. Consent is what the law calls it when he advances and she does not put up a fight. I have argued elsewhere that the kind of thin (...) consent that the law focuses on is not enough ethically and it should not be enough legally to justify sexual penetration. I advocate sexual negotiation, where individuals discuss sexual desires and boundaries and agree to engage in penetration before it occurs, except under circumstances in which the partners have a reasonable basis to assess one another's nonverbal behavior. I argue that not only is verbal consultation about desire ordinarily ethically necessary before most acts of sexual penetration, it should be legally required. Consultation to ascertain sexual desires and boundaries assures that both parties desire penetration. (shrink)

Abstract: The incorporation of Artificial Intelligence (AI) into educational technology has dramatically transformed learning through Intelligent Tutoring Systems (ITS). These systems utilize AI to offer personalized, adaptive instruction tailored to each student's needs, thereby improving learning outcomes and engagement. This paper examines the development and impact of ITS, focusing on AI technologies such as machine learning, natural language processing, and adaptive algorithms that drive their functionality. Through various case studies and applications, it illustrates how ITS have revolutionized traditional educational methods (...) and addresses the challenges and limitations, including data privacy and system biases. The discussion also covers future directions in ITS development, highlighting emerging trends and potential advancements. The goal is to provide a thorough understanding of how ITS use AI to enhance educational experiences and suggest avenues for future research in this evolving field. (shrink)

This article presents a new interpretation of the great Ming dynasty philosopher Wang Yangming’s celebrated doctrine of the “unity of knowledge and action”. Wang held that action was not unified with all knowledge, but only with an elevated form of knowledge, which he sometimes called “genuine knowledge”. I argue for a new interpretation of this notion, according to which genuine knowledge requires freedom from a form of doxastic conflict. I propose that, in Wang’s view, a person is free from this (...) form of doxastic conflict if and only if they are acting virtuously. (shrink)

Disagreement is one of the deepest and most pervasive topics in philosophy, arguably its very bedrock, and is an ever-increasing feature of politics, ethics, public policy, science and many other areas. Despite the omnipresence of disagreement, the topic itself has received relatively little sustained examination. In this outstanding handbook a team of international contributors examines the philosophy of disagreement and how it extends to debates in public policy and science. Comprising forty-one chapters by an international team of contributors, the Handbook (...) is divided into six clear parts: Philosophy of Disagreement Epistemology of Disagreement Disagreement about Science Moral Disagreement Disagreement in Politics Disagreement in Public Policy Within these sections key topics are examined, including: skepticism, truth, pluralism, feminist philosophy, experimental philosophy, epistemology of peer disagreement, rationality, intellectual virtue, relativism, realism, instrumentalism, scientific method and perspectivism. Ideal for those studying and researching philosophy, especially epistemology, ethics and philosophy of science, this handbook will also be of interest to those in related disciplines such as politics, social policy, and law.

AbstractThis essay argues for a new interpretation of the notion of “unity” in Yangming’s 王陽明 famous doctrine of the “unity of knowledge and action” (zhi xing he yi 知行合一). I distinguish two parts of Wang’s doctrine: one concerning training (gong fu 工夫), and one concerning the “original natural condition” of knowledge and action (ben ti 本體). I focus on the latter aspect of the doctrine, and argue that Wang holds, roughly, that a person exhibits knowledge in its original natural condition (...) if and only if the person exhibits action in its original natural condition. Moreover, I argue that Wang denies that knowledge in its original natural condition is identical to action in its original natural condition. (shrink)

This paper studies one aspect of the great Ming dynasty philosopher Wang Yangming’s (王陽明 1472-1529) celebrated doctrine of the unity of knowledge and action (zhi xing he yi 知行合一). Wang states that his doctrine does not apply to all knowledge, but only to an elevated form of knowledge, which he sometimes calls “genuine knowledge” (zhen zhi 真知). But what is “genuine knowledge”? I develop and compare four different interpretations of this notion: the perceptual, practical, normative and introspective models. The main (...) aim of the paper is to develop these models in more detail than has been done before. But at the end of the paper I argue that the introspective model is to be preferred over the alternatives. (shrink)

Anecdotal checklists are becoming more and more common in psychological practice nowadays, but they are not frequently employed in clinical psychology. This study focused on the use of anecdotal checklists in clinical practice and highlighted the experiences, perceptions, potential barriers, and challenges of the use of anecdotal checklists. A case study design was utilized in this study with one participant who utilized the anecdotal checklist during the intervention. The data was gathered through interviews and was analyzed using thematic analysis. Data (...) revealed that the participant expressed improved session structure and overwhelming paperwork and forms management. The participant perceived that using the checklist results in an effective collaboration and intervention. Moreover, challenges involve establishing the psychometric soundness of the checklist. The study highlights the potential benefits of using anecdotal checklists in providing psychological services. Additionally, the study emphasizes the need for further research focusing on the establishment of the psychometric properties of the checklist. (shrink)

This mixed methods study aims to determine the effects of the developed Gradual Release of Responsibility Instructional Model (GRRIM) learning module on the academic achievement of Grade 9 students in Geometry. The topic chosen for the module development is one of the students’ identified least learned competencies, particularly in parallelograms and their properties. The study participants were five (5) module development experts and 110 students grouped into control and experimental groups. The control group was exposed to DepEd SLM, while the (...) experimental group was exposed to GRRIM LM. Data were analyzed using thematic analysis, mean, independent samples t-test, and ANCOVA. The results of the thematic analysis of the focus group discussion revealed a module’s characteristics that embody the GRRIM approach’s different stages. Furthermore, findings indicated that after the intervention, the experimental group’s post-test mean scores were found to be at a moderate level. In contrast, the control group remained at a low level. Finally, the study revealed that when pre-test mean scores were treated as a covariate, there was a significant difference in the post-test mean scores between the control and experimental groups. The findings revealed that the students exposed to GRRIM LM performed better than those exposed to DepEd SLM. (shrink)

The coordinated attack scenario and the electronic mail game are two paradoxes of common knowledge. In simple mathematical models of these scenarios, the agents represented by the models can coordinate only if they have common knowledge that they will. As a result, the models predict that the agents will not coordinate in situations where it would be rational to coordinate. I argue that we should resolve this conflict between the models and facts about what it would be rational to do (...) by rejecting common knowledge assumptions implicit in the models. I focus on the assumption that the agents have common knowledge that they are rational, and provide models to show that denying this assumption suffices for a resolution of the paradoxes. I describe how my resolution of the paradoxes fits into a general story about the relationship between rationality in situations involving a single agent and rationality in situations involving many agents.

Robert Aumann presents his Agreement Theorem as the key conditional: “if two people have the same priors and their posteriors for an event A are common knowledge, then these posteriors are equal” (Aumann, 1976, p. 1236). This paper focuses on four assumptions which are used in Aumann’s proof but are not explicit in the key conditional: (1) that agents commonly know, of some prior μ, that it is the common prior; (2) that agents commonly know that each of them updates (...) on the prior by conditionalization; (3) that agents commonly know that if an agent knows a proposition, she knows that she knows that proposition (the “K K” principle); (4) that agents commonly know that they each update only on true propositions. It is shown that natural weakenings of any one of these strong assumptions can lead to countermodels to Aumann’s key conditional. Examples are given in which agents who have a common prior and commonly know what probability they each assign to a proposition nevertheless assign that proposition unequal probabilities. To alter Aumann’s famous slogan: people can “agree to disagree”, even if they share a common prior. The epistemological significance of these examples is presented in terms of their role in a defense of the Uniqueness Thesis: If an agent whose total evidence is E is fully rational in taking doxastic attitude D to P, then necessarily, any subject with total evidence E who takes a different attitude to P is less than fully rational.

I observe that the “concept-generator” theory of Percus and Sauerland (2003), Anand (2006), and Charlow and Sharvit (2014) does not predict an intuitive true interpretation of the sentence “Plato did not believe that Hesperus was Phosphorus”. In response, I present a simple theory of attitude reports which employs a fine-grained semantics for names, according to which names which intuitively name the same thing may have distinct compositional semantic values. This simple theory solves the problem with the concept-generator theory, but, as (...) I go on to show, it has problems of its own. I present three examples which the concept-generator theory can accommodate, but the simple fine-grained theory cannot. These examples motivate the full theory of the paper, which combines the basic ideas behind the concept-generator theory with a fine-grained semantics for names. The examples themselves are of interest independently of my theory: two of them constrain the original concept-generator theory more tightly than previously discussed examples had. (shrink)

Commentary on: Olaf Blanke, Thomas Metzinger, Full-body illusions and minimal phenomenal selfhood, Trends in Cognitive Sciences, Volume 13, Issue 1, January 2009, Pages 7-13, ISSN 1364-6613, DOI: 10.1016/j.tics.2008.10.003.

According to relationism, for Alice to believe that some rabbits can speak is for Alice to stand in a relation to a further entity, some rabbits can speak. But what could this further entity possibly be? Higher-order metaphysics seems to offer a simple, natural answer. On this view (roughly put), expressions in different syntactic categories (for instance: names, predicates, sentences) in general denote entities in correspondingly different ontological categories. Alice's belief can thus be understood to relate her to a sui (...) generis entity denoted by "some rabbits can speak", belonging to a different ontological category than Alice herself. This straightforward account of the attitudes has historically been deemed so attractive that it was seen as providing an important motivation for higher-order metaphysics itself (Prior [1971]). But I argue that it is not as straightforward as it might seem, and in fact that propositional attitudes present a foundational challenge for higher-order metaphysics. (shrink)

An opinionated introduction to philosophical issues connected to common knowledge.

Are LLMs cultural technologies like photocopiers or printing presses, which transmit information but cannot create new content? A challenge for this idea, which we call bibliotechnism, is that LLMs generate novel text. We begin with a defense of bibliotechnism, showing how even novel text may inherit its meaning from original human-generated text. We then argue that bibliotechnism faces an independent challenge from examples in which LLMs generate novel reference, using new names to refer to new entities. Such examples could be (...) explained if LLMs were not cultural technologies but had beliefs, desires, and intentions. According to interpretationism in the philosophy of mind, a system has such attitudes if and only if its behavior is well explained by the hypothesis that it does. Interpretationists may hold that LLMs have attitudes, and thus have a simple solution to the novel reference problem. We emphasize, however, that interpretationism is compatible with very simple creatures having attitudes and differs sharply from views that presuppose these attitudes require onsciousness, sentience, or intelligence (topics about which we make no claims).

In lieu of an abstract, here is a brief excerpt of the content:BENEDICT, THOMAS, OR AUGUSTINE? THE CHARACTER OF MACINTYRE'S NARRATIVE CHRISTOPHER J. THOMPSON University of St. Thomas St. Paul, Minnesota Introduction I N HIS Three Rival Versions of Moral Enquiry1 Alasdair Macintyre continues (with certain modifications) in a similar trajectory established in two earlier works, After Virtue and Whose Justice? Which Rationality? Against postEnlightenment portraits of moral reasoning, he consistently defends a conception of practical rationality which entails the recognition (...) of tradition, authority, and narrative as constitutive components of any rationally determined moral enquiry. Despite the consistent appeal to tradition, there is a significant development within Macintyre's reflections regarding the pre-eminent resources we are to draw upon. At the end of After Virtue we are asked to await a "doubtless very different" St. Benedict. In Whose Justice? Which Rationality? the Thomistic tradition emerges as the superior form of moral enquiry. While Thomism maintains a pre-eminence in Three Rival Versions of Moral Enquiry, I suggest that there is an increasingly Augustinian element emerging within his analysis and that this dimension underlies Macintyre's efforts in ways not previously specified. There is a warrant, then, for seeing within Augustine's efforts the paradigmatic "narrative form of moral enquiry." 1Alasdair Macintyre, Three Rival Versions of Moral Enquiry (Notre Dame: University of Notre Dame Press, 1990). Hereafter RV. 379 380 CHRISTOPHER J. THOMPSON That Augustine figures in Macintyre's reception of the Thomistic tradition is not necessarily striking, for part of what fuels Macintyre's increasing enthusiasm for St. Thomas is precisely the latter's capacity to draw upon the best of the Augustinian tradition of enquiry. Beyond what Macintyre himself has overtly recognized as Augustine's contribution to the thought of St. Thomas, however, I suggest that elements of Augustine's thought directly influence much of Macintyre 's own attempts at restoring a kind of tradition-guided enquiry. This Augustinian strain, moreover, not only serves to highlight features of Macintyre's analysis of Thomism, but also brings to light certain theological presuppositions essential to the kind of moral enquiry Macintyre hopes to retrieve. The character of Macintyre's narrative, then, leads us to St. Augustine. In After Virtue it is largely the Aristotelian tradition of enquiry which he defends against rival post-Enlightenment theories of morality. He argues that the analytic, linguistic, and phenomenological tools brought to bear upon the task of formulating a coherent conception of the moral life and moral enquiry have failed miserably, principally for two reasons. The first is that such contemporary efforts have neglected to realize that moral enquiry is embedded in a broader context of social practices, practices which are inevitably historically conditioned; thus a failure to recognize the historically situated character of moral enquiry distorts that account. The second reason is related to the first in that failure to acknowledge the historical character of such enquiry has resulted in a failure to recognize that much of our contemporary terms and tools of moral analysis are remnants from previous contexts of enquiry which are no longer mutually agreed upon nor recognized as relevant.' What has been lost, among other things, is the teleological metaphysics which serves as the context for nearly two millennia in the West. Uproot the stock of ethical norms from this tradition 2 For this notion of "moral remnants" surviving beyond the historical contexts in which they emerge, see Alasdair Macintyre, "Ought," Chapter 15 in Against the Self Images ofthe Age (New York: Schocken Books, 1971), 136-156, though in a different context and with very different effect. THE CHARACTER OF MACINTYRE 'S NARRATIVE 381 of enquiry and what remains is simply an amalgam of unrelated moral demands-some divinely sanctioned, some rooted in the passions, some the outburst of emotive whimsy-yet all lacking any coherent exposition.' The only hope is to retrieve something of the Aristotelian tradition of moral enquiry in which the notion of the virtues and the virtuous human person entails a conception of the moral life as bearing a narrative unity, a teleologically ordered whole in which one's actions bear an intrinsic unity and significance to the extent they complement one's telos. The narrative unity ascribed to the living of the good life is... (shrink)

Central elements of Roman Catholic treatment ethics include: 1) that rejection of treatment with the intent of hastening death (even for a good end) is ethically equivalent to active euthanasia with the same intent; 2) a distinction between morally obligatory “ordinary” treatment and morally optional “extraordinary treatment”; 3) that the quality of the patient’s life is not be a legitimate basis for rejecting treatment; and 4) that extraordinary treatment is not forbidden, but optional, and that it is the patient or (...) the patient’s legal surrogate–not the doctor– who has the right to choose or reject it. Despite these principles, even in a cultural climate fully sympathetic to Catholic treatment ethics, it is appropriate as a legal matter to maintain the doctrine of informed consent under which it is possible for patients or their surrogates to reject life-preserving treatment, including for unethical reasons. It is normally impossible to enforce in practice in the external forum a differentiation between rejection of treatment for ethically acceptable and ethically unacceptable reasons. By contrast, in cases of direct killing, such as assisting suicide, the intent to cause death is unmistakable (as opposed to accepting an increased risk of death as a foreseeable but unintended consequence of pursuing a good end). In a pluralistic society Catholic ethics cannot be legislatively enforced on the ground that they are compelled by Catholic teaching. However, the basic principles of Catholic treatment ethics may be justified based on logic and widely accepted norms of human equality independently of revelation or ecclesiastical authority. Particularly in protecting the right of individuals to choose and obtain life-saving medical treatment regardless of their “quality of life,” and in suicide prevention, secular law can and should be congruent with key aspects of Catholic health care ethics.

Time and space are conflated in time-warps when asleep we dream. Our wakeful cognitive ability to keep them separate indicates different ways of envisaging self-hood. Awareness that dream-time and life-time are separate is itself a propensity of human minds that has evolved by natural selection with adaptive developments in cerebral neuronal circuitry that underpin human behavioural complexity. The contrast is highlighted between how memory of our spatio-temporal experiences appears to be treated by our brain one way when we are wide-awake (...) and thus well aware of our unfolding personal life-history, and in a different way when, fast asleep, our dreaming dissolves any such awareness and our oneiric self-hood seems different from our real-life self-hood. The difference is considered from two angles. Regarding simultaneous memory-storage for an experience recalled from alternative perspectives, a theoretical possibility is proposed of a pro-system comparable to Cantor Ternary Set topology. Regarding the brain, the difference is considered in relation to the temporo-spatial theory of consciousness and the compatible concept of active inference forestalling surprisal by minimising variational free energy according to the free energy principle.

Remarks on method in the history of Chinese philosophy for analytic philosophy. (Published in a Chinese Translation.).

Berkeley in his Introduction to the Principles of Human knowledge uses geometrical examples to illustrate a way of generating “universal ideas,” which allegedly account for the existence of general terms. In doing proofs we might, for example, selectively attend to the triangular shape of a diagram. Presumably what we prove using just that property applies to all triangles.I contend, rather, that given Berkeley’s view of extension, no Euclidean triangles exist to attend to. Rather proof, as Berkeley would normally assume, requires (...) idealizing diagrams; treating them as if they obeyed Euclidean constraints. This convention solves the problem of representative generalization.

We provide a general argument against value incomparability, based on a new style of impossibility result. In particular, we show that, against plausible background assumptions, value incomparability creates an incompatibility between two very plausible principles for ranking lotteries: a weak "negative dominance" principle (to the effect that Lottery 1 can be better than Lottery 2 only if some possible outcome of Lottery 1 is better than some possible outcome of Lottery 2) and a weak form of ex ante Pareto (to (...) the effect that, if Lottery 1 gives an unambiguously better prospect to some individuals than Lottery 2, and equally good prospects to everyone else, then Lottery 1 is better than Lottery 2). After spelling out our results, and the arguments based on them, we consider which principle the proponent of incomparability ought to reject. (shrink)

Several theorists have observed that attitude reports have what we call “revisionist” uses. For example, even if Pete has never met Ann and has no idea that she exists, Jane can still say to Jim ‘Pete believes Ann can learn to play tennis in ten lessons’ if Pete believes all 6-year-olds can learn to play tennis in ten lessons and it is part of Jane and Jim’s background knowledge that Ann is a 6-year-old. Jane’s assertion seems acceptable because the claim (...) she reports Pete as believing is entailed by Pete’s beliefs if they are revised in light of Jane and Jim’s background knowledge. We provide a semantic theory of revisionist reports based on this idea. We observe that the admissible “revisions” are limited in a striking way. Jane cannot say ‘Pete thinks Ann is a 6-year-old and can play tennis in ten lessons’ in the same context that she can say ‘Pete believes Ann can learn to play tennis ten lessons’, even though this too follows from Jane and Jim’s background knowledge together with what Pete believes. Our theory predicts the infelicity of these latter reports. It also has the resources to predict the truth of “exported” attitude reports and casts the relationship between these reports and “singular thought” in a new light. We conclude by discussing how revisionist reports make trouble for a simplistic view of the connection between the relations expressed by attitude verbs in natural language and the relations of most interest to philosophers of mind and cognitive science.

Open peer commentary on the article “Constructivist Model Building: Empirical Examples From Mathematics Education” by Catherine Ulrich, Erik S. Tillema, Amy J. Hackenberg & Anderson Norton. Upshot: I argue that radical constructivism poses a series of deep methodological constraints on educational research. We focus on the work of Ulrich et al. to illustrate the practical implications of these constraints.

Mathematics educators are constantly searching for new and innovative approaches to teaching with the goal of improving student learning outcomes. This phenomenological study aimed to describe the lived experiences of mathematics teachers in implementing the Claim-Evidence-Reasoning (CER) Approach. The study was participated by 13 mathematics teachers, and data were gathered through in-depth interviews and a focus group discussion. Thematic analysis was used to interpret the data guided by Colaizzi’s method. Findings revealed that participants experienced struggles in instruction and assessment, adapted (...) growth mindset and employed support systems, had milestones in the implementation of the CER Approach, and were open to continuous personal and professional development. Furthermore, the teachers’ resiliency and adaptability in the process and the school’s support helped overcome the issues encountered in implementing the CER Approach. The findings imply that the use of CER Approach have the potential to improve the reasoning skills of students in mathematics. Further, it is recommended that mathematics teachers continue to utilize the approach and that educational institutions should provide proper training to teachers through In-Service Training (INSET).
