Does rationality require logical omniscience? Our best formal theories of rationality imply that it does, but our ordinary evaluations of rationality seem to suggest otherwise. This paper aims to resolve the tension by arguing that our ordinary evaluations of rationality are not only consistent with the thesis that rationality requires logical omniscience, but also provide a compelling rationale for accepting this thesis in the first place. This paper also defends an account of apriori justification for logical beliefs that is designed (...) to explain the rational requirement of logical omniscience. On this account, apriori justification for beliefs about logic has its source in logical facts, rather than psychological facts about experience, reasoning, or understanding. This account has important consequences for the epistemic role of experience in the logical domain. In a slogan, the epistemic role of experience in the apriori domain is not a justifying role, but rather an enabling and disabling role. (shrink)

Which beings have moral status? I argue that moral status requires some capacity for hedonic feelings of pleasure or displeasure. David Chalmers rejects this view on the grounds that it denies moral status to Vulcans, which are defined as conscious creatures with no capacity for hedonic feelings. On his more inclusive view, all conscious beings have moral status. We agree that only conscious beings have moral status, but we disagree about how to explain this. I argue that we cannot explain (...) why consciousness is necessary for moral status without denying that it is sufficient for moral status. Hence, we cannot exclude unconscious zombies without excluding conscious Vulcans too. (shrink)

What is the role of affective experience in explaining how our desires provide us with reasons for action? When we desire that p, we are thereby disposed to feel attracted to the prospect that p, or to feel averse to the prospect that not-p. In this paper, we argue that affective experiences – including feelings of attraction and aversion – provide us with reasons for action in virtue of their phenomenal character. Moreover, we argue that desires provide us with reasons (...) for action only insofar as they are dispositions to have affective experiences. On this account, affective experience has a central role to play in explaining how desires provide reasons for action. (shrink)

Perception enables us to think demonstrative thoughts about the world around us, but what must perception be like in order to play this role? Does perception enable demonstrative thought only if it is conscious? This paper examines three accounts of the role of consciousness in demonstrative thought, which agree that consciousness is essential for demonstrative thought, but disagree about why it is. First, I consider and reject the accounts proposed by Gareth Evans in The Varieties of Reference and by John (...) Campbell in Reference and Consciousness before offering an alternative proposal of my own. My proposal is that consciousness plays an essential epistemic role in explaining the capacity for demonstrative thought about an object by enabling the subject to form immediately justified beliefs about the object.

This paper argues that justification is accessible in the sense that one has justification to believe a proposition if and only if one has higher-order justification to believe that one has justification to believe that proposition. I argue that the accessibility of justification is required for explaining what is wrong with believing Moorean conjunctions of the form, ‘p and I do not have justification to believe that p.’.

This chapter defends the thesis that feeling conviction is sufficient for belief: if you feel conviction that p, then you believe that p. I begin with a neutral characterization of belief in terms of its normative profile: belief is a state that is subject to certain distinctive norms of rationality. The main argument of the chapter is that feelings of conviction are beliefs because they are subject to the same norms of rationality that govern our beliefs. Functionalists often deny that (...) feelings of conviction constitute beliefs when they play dysfunctional causal roles, as in cases of mad belief or delusion or implicit bias, but this only serves to obscure the kind of irrationality involved in such cases. These are dysfunctional beliefs, rather than non-doxastic states, or "in-between" cases. (shrink)

What is involved in making an inference? This chapter argues against what Paul Boghossian calls the Taking Condition: "Inferring necessarily involves the thinker taking his premises to support his conclusion and drawing his conclusion because of that fact" (2014: 5). I won’t argue that the Taking Condition is incoherent: that nothing can coherently play the role that takings are supposed to play in inference. Instead, I’ll argue that it cannot plausibly explain all the inferential knowledge that we ordinarily take ourselves (...) to have. Moreover, I’ll argue that we don’t need it to understand the nature of inference. (shrink)

According to the Rationality Constraint, our concept of belief imposes limits on how much irrationality is compatible with having beliefs at all. We argue that empirical evidence of human irrationality from the psychology of reasoning and the psychopathology of delusion undermines only the most demanding versions of the Rationality Constraint, which require perfect rationality as a condition for having beliefs. The empirical evidence poses no threat to more relaxed versions of the Rationality Constraint, which only require only minimal rationality. Nevertheless, (...) we raise problems for all versions of the Rationality Constraint by appealing to more extreme forms of irrationality that are continuous with actual cases of human irrationality. In particular, we argue that there are conceivable cases of “mad belief” in which populations of Lewisian madmen have beliefs that are not even minimally rational. This undermines Lewis’s claim that our ordinary concept of belief is a theoretical concept that is implicitly defined by its role in folk psychology. We argue that introspection gives us a phenomenal concept of belief that cannot be analyzed by applying Lewis’s semantics for theoretical terms. (shrink)

This is the first in a series of two articles that serve as an introduction to recent debates about cognitive phenomenology. Cognitive phenomenology can be defined as the experience that is associated with cognitive activities, such as thinking, reasoning, and understanding. What is at issue in contemporary debates is not the existence of cognitive phenomenology, so defined, but rather its nature and theoretical role. The first article examines questions about the nature of cognitive phenomenology, while the second article explores the (...) philosophical implications of these questions for the role of consciousness in theories of intentionality, introspective self-knowledge, and knowledge of the external world.

The aim of this paper is to argue that what I call the simple theory of introspection can be extended to account for our introspective knowledge of what we believe as well as what we consciously experience. In section one, I present the simple theory of introspection and motivate the extension from experience to belief. In section two, I argue that extending the simple theory provides a solution to Moore’s paradox by explaining why believing Moorean conjunctions always involves some degree (...) of irrationality. In section three, I argue that it also solves the puzzle of transparency by explaining why it’s rational to answer the question whether one believes that p by answering the question whether p. Finally, in section four, I defend the simple theory against objections by arguing that self-knowledge constitutes an ideal of rationality. (shrink)

This chapter argues that attention is a distinctive mode of consciousness, which plays an essential functional role in making information accessible for use in the rational control of thought and action. The main line of argument can be stated quite simply. Attention is what makes information fully accessible for use in the rational control of thought and action. But what makes information fully accessible for use in the rational control of thought and action is a distinctive mode of consciousness. Therefore, (...) attention is a distinctive mode of consciousness. In a slogan: attention is rational-access consciousness. (shrink)

In this chapter, I argue for the thesis that phenomenal consciousness is the basis of epistemic justification. More precisely, I argue for the thesis of phenomenal mentalism, according to which epistemic facts about which doxastic attitudes one has justification to hold are determined by non-epistemic facts about one’s phenomenally individuated mental states. I begin by providing intuitive motivations for phenomenal mentalism and then proceed to sketch a more theoretical line of argument according to which phenomenal mentalism provides the best explanation (...) of the independently motivated thesis of access internalism. The result is a theory of epistemic justification that brings intuition and theory into reflective equilibrium. (shrink)

This chapter provides a critical overview of several influential proposals about the epistemic function of higher-order evidence. I start by criticizing accounts of higher-order evidence that appeal to evidential defeat (§1), epistemic conflicts (§2), and unreasonable knowledge (§3). Next, I propose an alternative account that appeals to a combination of improper basing (§4) and non-ideal rationality (§5). Finally, I conclude by summarizing my reasons for preferring this account of higher-order evidence to the alternatives (§6).

Questions about the transparency of evidence are central to debates between factive and non-factive versions of mentalism about evidence. If all evidence is transparent, then factive mentalism is false, since no factive mental states are transparent. However, Timothy Williamson has argued that transparency is a myth and that no conditions are transparent except trivial ones. This paper responds by drawing a distinction between doxastic and epistemic notions of transparency. Williamson's argument may show that no conditions are doxastically transparent, but it (...) fails to show that no conditions are epistemically transparent. Moreover, this reinstates the argument from the transparency of evidence against factive mentalism. (shrink)

What is the connection between justification and truth in moral epistemology? The primary goal of this paper is to argue that you cannot have justified false beliefs about your own moral obligations. The secondary goal is to explain why not. Some epistemologists embrace a global truth-connection in epistemology, according to which epistemic justification is always factive. In contrast, I endorse a local truth-connection in moral epistemology, which says that epistemic justification is factive when it concerns your own moral obligations. To (...) explain this, I appeal to a version of moral rationalism, which says there are necessary truths about morality that everyone has a priori justification to believe. (shrink)

This chapter develops a simple theory of introspection on which a mental state is introspectively accessible just by virtue of the fact that one is in that mental state. This theory raises two questions: first, a generalization question: which mental states are introspectively accessible; and second, an explanatory question: why are some mental states introspectively accessible, rather than others, or none at all? In response to the generalization question, I argue that a mental state is introspectively accessible if and only (...) if it is phenomenally individuated. And in response to the explanatory question, I argue that a mental state is introspectively accessible if and only if it is among the determinants of justification. This provides the basis of an argument for a phenomenal conception of justification, according to which a mental state is among the determinants of justification if and only if it is phenomenally individuated.

This chapter is guided by the hypothesis that the point and purpose of using the concept of justification in epistemic evaluation is tied to its role in the practice of critical reflection. In section one, I propose an analysis of justification as the epistemic property in virtue of which a belief has the potential to survive ideal critical reflection. In section two, I use this analysis in arguing for a form of access internalism on which one has justification to believe (...) a proposition if and only if one has higher-order justification to believe that one has justification to believe that proposition. In section three, I distinguish between propositional and doxastic versions of access internalism and argue that the propositional version avoids familiar objections to the doxastic version. In section four, I argue that the propositional version of access internalism also explains and vindicates internalist intuitions about cases. In section five, I conclude with some reflections on the relationship between critical reflection, responsibility and personhood. (shrink)

This chapter is organized around four central questions about the role of reasons in the epistemology of perception. The 'whether?' question: does perception provide us with reasons for belief about the external world? The 'how?' question: how does perception provide us with reasons for belief about the external world? The 'when?' question: when does perception provide us with reasons for belief about the external world? The 'what?' question: what are the reasons that perception provides us with for belief about the (...) external world? (shrink)

Could there be a cognitive zombie – that is, a creature with the capacity for cognition, but no capacity for consciousness? Searle argues that there cannot be a cognitive zombie because there cannot be an intentional zombie: on this view, there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and intentionality. However, I argue that there are good empirical reasons for rejecting the proposed connection between consciousness and intentionality. Instead, I argue (...) that there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and rationality. On this view, there cannot be a cognitive zombie because there cannot be a rational zombie. (shrink)

In his book, On Reflection, Hilary Kornblith criticizes what he regards as a chronic tendency in philosophy towards inflating the significance of reflection in ways that manifest a combination of philosophical naiveté and scientific ignorance about how reflection actually works. In these comments, I respond to Kornblith's challenge by sketching an account of the philosophical significance of reflection in the theory of epistemic justification.

The main goal of this chapter is to argue that accessibilism in epistemology is incompatible with vehicle externalism in philosophy of mind. As we shall see, however, there are strong arguments for both of these positions. On the one hand, there is a compelling argument for vehicle externalism: the parity argument from Clark and Chalmers 1998. On the other hand, there is a compelling argument for accessibilism: the Moorean argument from Smithies 2012. If accessibilism is incompatible with vehicle externalism, then (...) both arguments cannot be sound. I resolve the tension by arguing that while the Moorean argument succeeds, the parity argument fails, and so vehicle externalism should be rejected on broadly epistemological grounds. (shrink)

What is the role of phenomenal consciousness in grounding epistemic justification? This paper explores the prospects for a global version of phenomenal conservatism inspired by the work of Michael Huemer, according to which all epistemic justification is grounded in phenomenal seemings. I’m interested in this view because of its global ambitions: it seeks to explain all epistemic justification in terms of a single epistemic principle, which says that you have epistemic justification to believe whatever seems to you strongly enough on (...) balance to be true. One of the attractions of phenomenal conservatism is that it offers such a simple and unified framework for explaining the epistemic role of phenomenal consciousness. I will argue, however, that the simplicity of phenomenal conservatism is not a theoretical virtue, but a theoretical vice, since it distorts the epistemological phenomena it is supposed to explain. In effect, phenomenal conservatism seeks to explain all epistemic justification on the same model as perception. But this has the predictable effect of distorting the epistemology of other domains, including introspection, inference, and a priori justification. (shrink)

In this paper, I argue that perception justifies belief about the external world in virtue of its phenomenal character together with its relations to the external world. But I argue that perceptual relations to the external world impact on the justifying role of perception only by virtue of their impact on its representational content. Epistemic level-bridging principles provide a principled rationale for avoiding more radically externalist theories of perceptual justification.

In his provocative and engaging new book, Perplexities of Consciousness, Eric Schwitzgebel makes a compelling case that introspection is unreliable in the sense that we are prone to ignorance and error in making introspective judgments about our own conscious experience. My aim in this commentary is to argue that Schwitzgebel’s thesis about the unreliability of introspection does not have the damaging implications that he claims it does for the prospects of a broadly Cartesian approach to epistemology.

How is moral knowledge possible? This paper defends the anti-Humean thesis that we can acquire moral knowledge by deduction from wholly non-moral premises. According to Hume’s Law, as it has become known, we cannot deduce an ‘ought’ from an ‘is’, since it is “altogether inconceivable how this new relation can be a deduction from others, which are entirely different from it” (Hume, 1739, 3.1.1). This paper explores the prospects for a deductive theory of moral knowledge that rejects Hume’s Law.

This chapter has two goals: to motivate the foundationalist solution to the regress problem and to defend it against arguments from Sellars, BonJour and Klein. Both the motivation and the defence of foundationalism raise larger questions about the relationship between foundationalism and access internalism. I argue that foundationalism is not in conflict with access internalism, despite influential arguments to the contrary, and that access internalism in fact supplies a theoretical motivation for foundationalism. I conclude that foundationalism and access internalism form (...) a coherent and well-motivated package. (shrink)

Psychiatric and neurological disorders have historically provided key insights into the structure-function rela- tionships that subserve human social cognition and behavior, informing the concept of the ‘social brain’. In this review, we take stock of the current status of this concept, retaining a focus on disorders that impact social behavior. We discuss how the social brain, social cognition, and social behavior are interdependent, and emphasize the important role of development and com- pensation. We suggest that the social brain, and its (...) dysfunction and recovery, must be understood not in terms of specific structures, but rather in terms of their interaction in large-scale networks.

This article investigates the semantics of sentences that express numerical averages, focusing initially on cases such as 'The average American has 2.3 children'. Such sentences have been used both by linguists and philosophers to argue for a disjuncture between semantics and ontology. For example, Noam Chomsky and Norbert Hornstein have used them to provide evidence against the hypothesis that natural language semantics includes a reference relation holding between words and objects in the world, whereas metaphysicians such as Joseph Melia and (...) Stephen Yablo have used them to provide evidence that apparent singular reference need not be taken as ontologically committing. We develop a fully general and independently justified compositional semantics in which such constructions are assigned truth conditions that are not ontologically problematic, and show that our analysis is superior to all extant rivals. Our analysis provides evidence that a good semantics yields a sensible ontology. It also reveals that natural language contains genuine singular terms that refer to numbers. (shrink)

While artificial womb technology is currently being studied for the purpose of improving neonatal care, I contend that this technology ought to be pursued as a means to address the unprecedented rate of unintended pregnancies. But ectogenesis, alongside other emerging reproductive technologies, is problematic insofar as it threatens to disrupt the natural link between procreation and parenthood that is normally thought to generate rights and responsibilities for biological parents. I argue that there remains only one potentially viable account of parenthood: (...) the voluntarist account, which construes parental rights as robust moral obligations that must be voluntarily undertaken. The problem is that this account mistakenly presumes a patriarchal divide between procreation and parenthood. I propose a reframing of procreation and parenthood from a feminist perspective that recognises gestational motherhood as involving robust moral obligations that ought to be voluntarily undertaken. If this were the case, all gestational mothers would be, by definition, willing mothers. To make this happen I argue that ectogenesis technology must be a widely available reproductive option.

Suicide is a complex act whose meanings, while sometimes tragic, vary widely. This chapter surveys the ethical landscape surrounding algorithmic methods of suicide prevention especially as it pertains to social media activity and to the moderation of online suicide communities. We begin with a typology of suicide, distinguishing between varied goals in which suicide may factor as a means. Suicides should be understood as an act with varied eliciting desires, meanings, consequences, and ethics. Further,while many suicides may be grounded on (...) irrational desire, we argue that a desire to suicide may nonetheless be rational in some cases. We then offer a survey of the attempts by social media corporations to create suicide prediction algorithms and launch interventions aimed at preventing suicide as well as an overview of the current ethical debate. We argue that the values embedded within algorithmic suicide prevention nudges are “thick” in a substantive sense and deserving of scrutiny. Given that debates about the rationality, meaning, and permissibility of suicide are common and subject to intracultural and cross-cultural differences, we maintain that the task of suicide prediction is ill-suited to algorithmic approaches. Despite an algorithm’s ability to quantify a complex phenomenon like suicide risk and its appearance of objectivity, any suicide prediction algorithm is thoroughly subjective and involves moral judgments all the way down. Any such algorithm would necessarily impose a normative stance on suicide onto its user base that is subject to reasonable intra and cross-cultural disagreement. (shrink)

We lead off this issue of Childhood and Philosophy with a collection of testimonies, homages, and brief memoirs offered from around the world in response to the death of the founder of Philosophy for Children, Matthew Lipman on December 26, 2010, at the age of 87. To characterize Lipman as “founder” is completely accurate, but barely evokes the role he played in conceiving, giving birth to, and nurturing this curriculum cum pedagogy that became a movement, and which has taken root (...) in over 40 countries, from Iceland to Nigeria to Taiwan to Chile and everywhere in between. The movement itself is broader than the program, which has in fact experienced multiple transformations in multiple contexts over its half-century of life. In fact, as many of the testimonies below either state outright or imply, the movement is an emancipatory one and thus implicitly political, infused with all the long-suffering hope for our species inspired in us by the fact of natality, and by our own intuitive faith in the transformative power of reason—or as Lipman came to call it, “reasonableness.” For those seized by its educational possibilities, it presents a sudden influx of sunlight and fresh air into an institution long stultified by its own rigid habitus, and promises the reconstruction of schooling in the image of authentic democratic practice that recognizes and honors the unique capacities of children. As Philosophy in the Classroom—Lipman’s first and now classic statement of educational philosophy--puts it, the movement promises a re-orientation of the goal of education from information (or “learning”) to meaning, and inaugurates the dialogue with childhood and children that follows from that. Lipman was not just founder of this movement but creator, inventor, developer, convener, organizer, faithful soldier, ambassador, apologist, polemicist, propagandist, and, finally, undying optimist.

At the very least, even though Chinese schools do not look very different from those in the West, China offers an opportunity for Philosophy for Children to question its basis, its methodology, its aims. It seems to be expressing a different cultural voice, and to be disposed to the kind of dialogue we are more used to claiming than practicing. Both Kunming and Shanghai provide, in their own ways, formidable contexts: the deep, strong and disciplined educators of Railway Station School (...) of Kunming and the scholarly, sophisticated and committed members of the Shanghai institute for Research in the Human Sciences seem determined to take Philosophy for Children, not just beyond their own limits as Chinese, but beyond the limits Philosophy for Children has already established for itself in the West. Philosophy for Children in China, then, looks like a wonderful opportunity to think ourselves--what we are as educators engaged in the practice of philosophy--again. An invitation to think ourselves again. Is this not what dialogue and philosophy are about? It’s up to us to accept the invitation. (shrink)

The present volume collects presented at a symposium on The History of Logic held in Helsinki in June 11–13, 2000 hosted by the University of Helsinki, Finland. They bear on issues in the history of logic and foundations of mathematics and are contributions by some of the most renown scholars in the field.

Scientific information plays an important role in shaping policies and recommendations for behaviors that are meant to improve the overall health and well-being of the public. However, a subset of the population does not trust information from scientific authorities, and even for those that do trust it, information alone is often not enough to motivate action. Feelings of shame can be motivational, and thus some recent public policies have attempted to leverage shame to motivate the public to act in accordance (...) with science-based recommendations. We argue that because these shame policies are employed in non-communal contexts, they are both practically ineffective and morally problematic: shame is unlikely to be effective at motivating the public to behave in accordance with science-based policy, and shaming citizens is an unethical way to get them to comply. We argue that shame-based policies are likely to contribute to further distrust in scientific authority. (shrink)

This paper works out the scheme of “institutional competences” that underlies the famous Hart and Sacks Legal Process Materials first distributed in final mimeographed form in1958. The Materials were not published during the life times of their authors but were nonetheless a major influence on American legal thought from their first distribution as course materials at Harvard Law School until their abrupt fall from prominence in the early 1970s. The Materials offer the scheme as a solution to the apparent anomaly (...) in a democracy of the law making power in both public and private law of unelected judges serving long terms. The paper critiques the Hart and Sacks solution, called law making through “reasoned elaboration,” which they claimed was sharply distinct from legislative law making or administrative fiat. The paper argues that in both public and private law the materials the judge is to elaborate are characterized by contradictory internal logics. The judge has to choose between them without a meta-criterion. In cases with high stakes, extra-juristic normative orientations, whether moral theories or political ideologies, will come into play, regardless of the judge’s commitment to excluding them. The second part of the paper places Hart and Sacks in a larger historical and comparative context of efforts to solve the problem of social order by way of legal rationality. These two parts were preceded in the original paper by a long discussion, now lost but never very satisfying to me, of the Hart and Sacks theory of “private ordering” in relation to state regulatory power. I wrote the paper for extra credit in the spring of 1970 as a third year student at the Yale Law School. I’ve corrected a few typos but haven’t changed it in any other way. I never published it but it was circulated to a limited extent among Legal Process devotees. Eskridge and Frickey, editors of the Materials as published finally in 1994, credit it, along with another unpublished student paper by Roberto Unger, with hastening the demise of the Materials as a master text. The first part of this version of the paper was recently published in Droit et Philosophie, no. 13, p. 97-117 (2021). (shrink)

The purpose of this chapter is to describe what we see as several important new directions for philosophy of medicine. This recent work (i) takes existing discussions in important and promising new directions, (ii) identifies areas that have not received sufficient and deserved attention to date, and/or (iii) brings together philosophy of medicine with other areas of philosophy (including bioethics, philosophy of psychiatry, and social epistemology). To this end, the next part focuses on what we call the “epistemological turn” in (...) recent work in the philosophy of medicine; the third part addresses new developments in medical research that raise interesting questions for philosophy of medicine; the fourth part is a discussion of philosophical issues within the practice of diagnosis; the fifth part focuses on the recent developments in psychiatric classification and scientific and ethical issues therein, and the final part focuses on the objectivity of medical research.

Indiscipline in schools has attracted the attention of many people and has eventually become the focus of discussions on many platforms. The purpose of the study was to find out the perceptions of teachers and students at the Abuakwa South Municipality of Ghana on student indiscipline behaviours. The study employed the descriptive survey and the approach was concurrent mixed method, involving bothquantitative and qualitative paradigms. Purposive and simple random sampling methods were used to obtaina sample size of five hundred and (...) thirty (530) respondents. The main instruments used for the study were questionnaire and a semi-structured interview guide. Data was analysed using inferential statistics and content analysis. Findings from the study revealed that; there was no perceptual difference between students and teachers views on acts that constitute disciplinary behaviours. Additional, there were differences in thestudents and teachers perceptions of the influences of peer pressure on students’ disciplinary behaviours. Itwas recommended among others that peer counselling sessions should be organized periodically among students for them to be aware of acceptable behaviours in the school system and how they can maintain desirable behaviours.

The concept of interactional expertise – characterized by sociologists Harry Collins and Robert Evans as the ability to speak the language of a discipline without the corresponding ability to practice – can serve as a powerful way of breaking down expert/non-expert dichotomies and providing a role for new voices in specialist communities. However, in spite of the vast uptake of this concept and its potential to fruitfully address many important issues related to scientific expertise, there has been surprisingly little critical (...) analysis of it. We seek to remedy this situation by considering potential benefits of interactional expertise and the ways in which the current conception can – and cannot – realize those benefits. In particular, we argue that interactional expertise hasn’t reached its full potential for addressing who ought to be involved in scientific research and decision-making, largely owing to an unnecessarily restrictive way of operationalizing the concept. In its place, we offer a broader, more pluralistic account of interactional expertise – one that is in line with the original spirit of the concept, but also captures the diversity that we see as being an important aspect of interactional experts and the value they can bring to the table.

Broadening access to both computational and educational resources is crit- ical to diffusing machine learning (ML) innovation. However, today, most ML resources and experts are siloed in a few countries and organizations. In this article, we describe our pedagogical approach to increasing access to applied ML through a massive open online course (MOOC) on Tiny Machine Learning (TinyML). We suggest that TinyML, applied ML on resource-constrained embedded devices, is an attractive means to widen access because TinyML leverages low-cost and globally (...) accessible hardware and encourages the development of complete, self-contained applications, from data collection to deployment. To this end, a collaboration between academia and industry produced a four part MOOC that provides application-oriented instruction on how to develop solutions using TinyML. The series is openly available on the edX MOOC platform, has no prerequisites beyond basic programming, and is designed for global learners from a variety of backgrounds. It introduces real-world applications, ML algorithms, data-set engineering, and the ethi- cal considerations of these technologies through hands-on programming and deployment of TinyML applications in both the cloud and on their own microcontrollers. To facili- tate continued learning, community building, and collaboration beyond the courses, we launched a standalone website, a forum, a chat, and an optional course-project com- petition. We also open-sourced the course materials, hoping they will inspire the next generation of ML practitioners and educators and further broaden access to cutting-edge ML technologies. (shrink)

Since its introduction just over two decades ago, evidence-based medicine (EBM) has come to dominate medical practice, teaching, and policy. There are a growing number of textbooks, journals, and websites dedicated to EBM research, teaching, and evidence dissemination. EBM was most recently defined as a method that integrates best research evidence with clinical expertise and patient values and circumstances in the treatment of patients. There have been debates throughout the early 21st century about what counts as good research evidence between (...) EBM proponents and philosophical critics and even within the EBM community itself. Similar controversy arises about the relative worth of patient values and clinical expertise (and how these can be integrated). EBM has also evolved in ways that have come under scrutiny. Specifically, policymakers have used EBM research methodology to increase the relative importance of clinical guidelines that some clinicians have argued are tyrannical. Philosophers have addressed all of these controversies, and with very few exceptions have been critical of EBM. In addition most philosophical attention has been on the epistemic role of Randomization and evidence hierarchies, with relatively little attention being paid to the role of Diagnosis, expertise, patient values, and Systematic Reviews within EBM.

In his famous 1982 paper, Allen Newell [22, 23] introduced the notion of knowledge level to indicate a level of analysis, and prediction, of the rational behavior of a cognitive arti cial agent. This analysis concerns the investigation about the availability of the agent knowledge, in order to pursue its own goals, and is based on the so-called Rationality Principle (an assumption according to which "an agent will use the knowledge it has of its environment to achieve its goals" [22, (...) p. 17]. By using the Newell's own words: "To treat a system at the knowledge level is to treat it as having some knowledge, some goals, and believing it will do whatever is within its power to attain its goals, in so far as its knowledge indicates" [22, p. 13]. In the last decades, the importance of the knowledge level has been historically and system- atically downsized by the research area in cognitive architectures (CAs), whose interests have been mainly focused on the analysis and the development of mechanisms and the processes governing human and (arti cial) cognition. The knowledge level in CAs, however, represents a crucial level of analysis for the development of such arti cial general systems and therefore deserves greater research attention [17]. In the following, we will discuss areas of broad agree- ment and outline the main problematic aspects that should be faced within a Common Model of Cognition [12]. Such aspects, departing from an analysis at the knowledge level, also clearly impact both lower (e.g. representational) and higher (e.g. social) levels. (shrink)

Mark Colyvan formulates a puzzle about belief in inconsistent entities. As a scientific realist, Colyvan refers to salient instances of inconsistencies in our best science and demonstrates how an indispensability argument may justify belief in an inconsistent entity. Colyvan’s indispensability argument presents a two-horned dilemma: either scientific realists are committed to the possibility of warranted belief in inconsistent objects, or we have a reductio ad absurdum, bringing realism into a crisis. Firstly, this paper follows Graham Priest by opposing the received (...) characterisation of inconsistent belief as a kind of epistemic hell. Secondly, I challenge the Quinean naturalism that underpins Colyvan’s indispensability argument. Then, I reformulate Colyvan’s argument with a fallible naturalism, better equipped to account for certain problem candidates for inconsistent entities. Finally, I contend that—even if indispensable—an inconsistent entity poses no problem for the scientific realist, who can have justified belief in inconsistent entities. (shrink)

Declan Smithies’ The Epistemic Role of Consciousness argues for “phenomenal mentalism,” according to which justification is determined synchronically and solely by phenomenally individuated mental states. Moreover, part I of the book argues for a few specific epistemic principles about perception, cognition, and introspection. My comments focus on the discussion of these specific principles and raise worries about the consistency with other ideas in the book, and about the arguments for these principles.

This is an excellent collection of essays on introspection and consciousness. There are fifteen essays in total (all new except for Sydney Shoemaker’s essay). There is also an introduction where the editors explain the impetus for the collection and provide a helpful overview. The essays contain a wealth of new and challenging material sure to excite specialists and shape future research. Below we extract a skeptical argument from Fred Dretske’s essay and relate the remaining essays to that argument. Due to (...) space limitations we focus in detail on just a few of the essays. We regret that we cannot give them all the attention they merit. (shrink)

Wolfgang Spohn's theory of ranking functions is an elegant and powerful theory of the structure and dynamics of doxastic states. In two recent papers, Spohn has applied it to the analysis of conditionals, claiming to have presented a unified account of indicative and subjunctive (counterfactual) conditionals. I argue that his analysis fails to account for counterfactuals that refer to indirect causes. The strategy of taking the transitive closure that Spohn employs in the theory of causation is not available for counterfactuals. (...) I have a close look at Spohn's treatment of the famous Oswald-Kennedy case in order to illustrate my points. I sketch an alternative view that seems to avoid the problems. (shrink)
