(For English, scroll down) „Kreativität“ ist ein sehr junger Begriff und ein sehr altes Phänomen. Sie gilt als unaufklärbares Rätsel, als eine Art „Black Box“ des Denkens. Dem kollektiven Bewußtsein zufolge ist sie etwas Rares, Flüchtiges, strapaziös zu erzielen und nur wenige Glückliche begünstigend. Das vorliegende Buch präsentiert eine logische Grundidee zur Entstehung von schöpferisch Neuem – Elemente aus Logik, Symbotheorie, Informations-, Kommunikations- und Medientheorie verbindend. Diese „Formel“ wird an philosophischen Stationen von der Antike bis zur Gegenwart erprobt und weiterentwickelt, (...) darunter Theorien von Platon, Aristoteles, Leibniz, Baumgarten, Kant, Wittgenstein, Nelson Goodman und Gregory Bateson. Kreativität zeigt sich als ein Transformationsphänomen, welches das Denken auf eine andere logische Ebene führt, kategoriale Grenzen transformiert und Anschlußformen öffnet. Im Ergebnis ist sie nichts per Definition Abwesendes, erreichbar nur über den Umweg von unverfügbarer Gunst, weltabgewandter Passion oder verborgenen Tricks. Kreativität ist vielmehr omnipräsent, schöpferische Energien sind nur mit großem Aufwand zu unterdrücken, und die Frage, wie man sie erreicht, wird zur Frage, wie man ihr eine optimale Basis bereitet, ohne sie wesentlich zu behindern. Creativity" is a young term and an old phenomenon. It is considered an unexplainable enigma, a kind of "black box" of thought. According to the default view, it is something rare, fleeting, hard to achieve and favoring only a lucky few. The present book presents a logical formula for the emergence of creative newness - combining elements from logic, theories of symbolization, information-theory, communication- and media theories. This structural idea is tested and further developed by confronting it with select philosophical theories regarding the production of ‘newness’ from antiquity to the present, including theories by Plato, Aristotle, Leibniz, Baumgarten, Kant, Wittgenstein, Nelson Goodman and Gregory Bateson. As a result, creativity shows up as a transformation phenomenon, including different logical levels, thereby transforming categorical boundaries. As a result, it is not something mostly absent, attainable only through of luck, manic passion, or hidden tricks. Creativity is rather omnipresent, creative energies can only be suppressed with great effort, and the question of how to achieve it becomes the question of how to prepare an optimal basis without significantly hindering it.

Consider the sentence “Lois knows that Superman flies, but she doesn’t know that Clark flies”. In this paper we defend a Millian contextualist semantics for propositional attitude ascriptions, according to which ordinary uses of this sentence are true but involve a mid-sentence shift in context. Absent any constraints on the relevant parameters of context sensitivity, such a semantics would be untenable: it would undermine the good standing of systematic theorizing about the propositional attitudes, trivializing many of the central questions of (...) epistemology, the philosophy of mind, and the philosophy of action. In response to this problem, we prove a series of tenability results. We show that, given certain constraints on the parameters of context sensitivity, there is a broad class of principles of propositional attitude psychology whose good standing follows from corresponding claims about people’s mental representations. But these constraints also have some surprising consequences: they are jointly incompatible with coarse-grained theories of propositions, and they are in tension with a natural picture of how speakers and hearers coordinate on the interpretation of attitude ascriptions. In light of these consequences we explore different ways in which the contextualist picture might be developed, and argue that our preferred way compares favorably with Fregeanism and neo-Russellianism.

We offer an interpretation of the mental files framework that eliminates the metaphor of files, information being contained in files, etc. The guiding question is whether, once we move beyond the metaphors, there is any theoretical role for files. We claim not. We replace the file-metaphor with two theses: the semantic thesis that there are irreducibly relational representational facts (viz. facts about the coordination of representations); and the metasemantic thesis that processes tied to information-relations ground those facts. In its canonical (...) statement, the ‘file’-theory makes reference to a certain kind of relational representational feature, and a certain kind of mental activity. Mental files need not come into it. In short, we posit mental filing without mental files. Our interpretation avoids awkward problems that arise on the standard interpretation and clarifies the explanatory commitments of the theory. (shrink)

We offer a general framework for theorizing about the structure of knowledge and belief in terms of the comparative normality of situations compatible with one’s evidence. The guiding idea is that, if a possibility is sufficiently less normal than one’s actual situation, then one can know that that possibility does not obtain. This explains how people can have inductive knowledge that goes beyond what is strictly entailed by their evidence. We motivate the framework by showing how it illuminates knowledge about (...) the future, knowledge of lawful regularities, knowledge about parameters measured using imperfect instruments, the connection between knowledge, belief, and probability, and the dynamics of knowledge and belief in response to new evidence.

How is what we believe related to how we act? That depends on what we mean by ‘believe’. On the one hand, there is what we're sure of: what our names are, where we were born, whether we are sitting in front of a screen. Surety, in this sense, is not uncommon — it does not imply Cartesian absolute certainty, from which no possible course of experience could dislodge us. But there are many things that we think that we are (...) not sure of. For example, you might think that it will rain sometime this month, but not be sure that it will. Both what we're sure of and what we think have important normative connections to action. But the connections are quite different. This paper explores these issues with respect to assertion, inquiry, and decision making. We conclude by arguing that there is no theoretically significant notion of ‘full belief’ intermediate in strength between thinking and being sure. (shrink)

On the traditional relationalist conception of singular thought, a thought has singular content when it is based on an ‘information relation’ to its object. Recent work rejects relationalism and suggests singular thoughts are distinguished from descriptive thoughts by their inferential role: only thoughts with singular content can be employed in ‘direct’ inferences, or inferences that ‘trade on identity’. Firstly this view is insufficiently clear, because it conflates two distinct ideas—one about a kind of inference, the other a kind of process (...) that grounds inferences—under the title, ‘trading on identity’. Secondly, this leaves us without a notion that can be used as an alternative to relationalism about singular thought. The first notion is no more applicable to singular than to descriptive thought. The second may help us better understand singular thought, but does so, not by replacing the view that singular thoughts are information-based, but by helping us understand the nature of information-based thought.

This essay is an investigation into the sense of ‘able’ relevant to free will, where free will is understood as requiring the ability to do otherwise. I argue that van Inwagen's recent functional specification of the relevant sense of ‘able’ is flawed, and that explicating the powers involved in free will shall likely require paying detailed attention to the semantics and pragmatics of ‘can’ and ‘able’. Further, I argue that van Inwagen's promise-level ability requirement on free will is too strong. (...) I also argue that Mele's conjecture that the strength of the ability to perform the ‘alternative’ action be no higher than the strength of the ability exercised in performing an action is mistaken. I suggest there is an asymmetry in the strengths of the abilities which make up the n-way power that comprises free will, and that this looks to have some interesting consequences for the connection between the abilities required for free will and, e.g. the ‘up to us’ locution.

Although digital breast tomosynthesis has higher sensitivity than digital mammography and at least as high specificity, digital mammography remains the most common method for conducting mammographic screening. At the same time, mammography systems are now delivered “DBT-ready” and can be used for either digital mammography or digital breast tomosynthesis. In this paper, we ask whether it is ethically permissible to use such equipment for digital mammography, given its lower sensitivity. We argue it is not, and that clinics are ethically required (...) to use their DBTready equipment to screen with digital breast tomosynthesis whenever this is practically possible. Our argument relies on a comparison between digital breast tomosynthesis and a hypothesized improvement in the image quality of digital mammography. (shrink)

The so-called ‘mental files theory’ in the philosophy of mind stems from an analogy comparing object-concepts to ‘files’, and the mind to a ‘filing system’. Though this analogy appears in philosophy of mind and language from the 1970s onward, it remains unclear to many how it should be interpreted. The central commitments of the mental files theory therefore also remain unclear. Based on influential uses of the file analogy within philosophy, I elaborate three central explanatory roles for mental files. Next, (...) I outline several common criticisms of the file picture, which have been a source of resistance to the view. Finally, I outline several interpretations of the theory, thus highlighting that the best interpretation of the file-theory's central analogy remains a live issue. (shrink)

We show that, contrary to conventional wisdom, Frege’s distinction between sense and reference does not reconcile a classical logic of identity with apparent counterexamples to it involving proper names embedded under propositional attitude verbs.

This chapter offers an opinionated introduction to higher-order formal languages with an eye towards their applications in metaphysics. A simply relationally typed higher-order language is introduced in four stages: starting with first-order logic, adding first-order predicate abstraction, generalizing to higher-order predicate abstraction, and finally adding higher-order quantification. It is argued that both β-conversion and Universal Instantiation are valid on the intended interpretation of this language. Given these two principles, it is then shown how we can use pure higher-order logic to (...) ask, and begin to answer, metaphysical questions with non-trivial implications. In particular, while we must reject the popular idea that structural differences between sentences correspond to parallel distinctions in the logical structure of extra-linguistic reality, it may still be possible to give a purely logical characterization of objectual aboutness and related notions.

This paper’s most general aim is to illuminate the disagreement between singularists about thought (who claim there are non-descriptive thoughts about ordinary external objects), and descriptivists about thought (who claim all thought about ordinary external objects is descriptive). It does this by clarifying the common claim that singular thoughts have an anchoring role with respect to thought in general and by making two further claims: 1) some of the putative disagreements between singularists and descriptivists are illusory once properly understood, and (...) 2) singularists can more productively argue for their view by separating it from some of the framework in which it is commonly packaged. Separating the singular/descriptive thought distinction from the structured content framework, and casting the singularist’s central claim as one about the structure or form of what I will call referentially anchored thoughts, allows us to move past a common kind of impasse.

In an essay on performance-enhancing drugs, author Chuck Klosterman (2007) argues that the category of enhancers extends from hallucinogens used to inspire music to steroids used to strengthen athletes—and he criticizes those who would excuse one means of enhancement while railing against the other as a form of cheating: After the summer of 1964, the Beatles started taking serious drugs, and those drugs altered their musical performance. Though it may not have been their overt intent, the Beatles took performance-enhancing drugs. (...) And . . . absolutely no one holds it against them.

Conditional excluded middle (CEM) is the following principe of counterfactual logic: either, if it were the case that φ, it would be the case that ψ, or, if it were the case that φ, it would be the case that not-ψ. I will first show that CEM entails the identity of indiscernibles, the falsity of physicalism, and the failure of the modal to supervene on the categorical and of the vague to supervene on the precise. I will then argue that (...) we should accept these startling conclusions, since CEM is valid. (shrink)

This paper is about the relevance of attitude-ascriptions to debates about singular thought. It examines a methodology (common to early acquaintance theorists [Kaplan 1968] and recent critics of acquaintance [Hawthorne and Manley 2012], which assumes that the behaviour of ascriptions can be used to draw conclusions about singular thought. Although many theorists (e.g. [Recanati 2012]) reject this methodology, the literature lacks a detailed examination of its implications and the challenges faced by proponents and critics. I isolate an assumption of the (...) methodology, which I call the tracking assumption: that an attitude-ascription which states that s Φ's that P is true iff s has an attitude, of Φ-ing, which is an entertaining of the content P (with entertain used in a stipulated sense). I argue that the tracking assumption must be rejected, not because it has deflationary consequences, but because it leads to unstable commitments. I also show that there are independent reasons to reject it, because ordinary attitude ascriptions underdetermine even the truth-conditions of the mental-states they ascribe. However, I argue, this does not involve rejecting the claim that attitude-ascriptions express relations between agents and contents. Instead, they state different relations depending on contextual factors other than the nature of the mental-states ascribed. (shrink)

In Talking about, Unnsteinsson defends an intentionalist theory of reference by arguing that confused referential intentions degrade reference. Central to this project is a “belief model” of both identity confusion and unconfused thought. By appealing to a well‐known argument from Campbell, I argue that this belief model falls short, because it fails to explain the inferential behavior it promises to explain. Campbell's argument has been central in the contemporary literature on Frege's puzzle, but Unnsteinsson's account of confusion provides an opportunity (...) for more clarity about how the argument is best interpreted, and what it shows.

This paper investigates a generalization of Boolean algebras which I call agglomerative algebras. It also outlines two conceptions of propositions according to which they form an agglomerative algebra but not a Boolean algebra with respect to conjunction and negation.

Certain realists about properties and relations identify them with universals. Furthermore, some hold that for a wide range of meaningful predicates, the semantic contribution to the propositions expressed by the sentences in which those predicates figure is the universal expressed by the predicate. I here address ontological issues raised by predicates first introduced to us via works of fiction and whether the universal realist should accept that any such predicates express universals. After assessing arguments by Braun, D. and Sawyer, S. (...) for fictional universal anti-realism, I propose a novel, Kripke-inspired argument for the same conclusion. I ultimately defend the claim that while this argument presents the strongest case for fictional universal anti-realism, it is nonetheless unsound. I conclude that nothing stands in the way of accepting that some fictional predicates express fictional universals. (shrink)

According to traditional versions of the mental file theory, we should posit _mental files_—that is, mental representations with containment structure—to explain both rational relations between the attitudes, and the persistence of the attitudes across time. However, Goodman and Gray ( 2022 ) offer a revisionary interpretation of the file framework, according to which its explanatory commitments are better presented by positing _mental filing_, as a process, but not _mental files_, as mental representations with file structure. Goodman and Gray (...) focus on a certain class of synchronic explanations, but files have also been thought to play an essential diachronic role in the maintenance and update of object-directed thought. This paper has two aims. First, we clarify the aims and commitments of Goodman and Gray ( 2022 ). Second, we extend their mental filing view to show how it can account for continued belief, change of mind and persistence of the attitudes in general. (shrink)

It has become popular of late to identify the phenomenon of thinking a singular thought with that of thinking with a mental file. Proponents of the mental files conception of singular thought claim that one thinks a singular thought about an object o iff one employs a mental file to think about o. I argue that this is false by arguing that there are what I call descriptive mental files, so some file-based thought is not singular thought. Descriptive mental files (...) are mental files for which descriptive information plays four roles: determines which object the file is about, if any, it sets limits on possible mistakes that fall within the scope of successful reference for the file, it acts as a ‘gatekeeper’ for the file, and it determines persistence conditions for the file. Contrary to popular assumption, a description playing these roles is consistent with the file-theoretic framework. Recognising this allows us to distinguish the notion of singular thought from that of file-thinking and better understand the nature and role of both. (shrink)

This paper has a narrow and a broader target. The narrow target is a particular version of what I call the mental-files conception of singular thought, proposed by Robin Jeshion, and known as cognitivism. The broader target is the MFC in general. I give an argument against Jeshion's view, which gives us preliminary reason to reject the MFC more broadly. I argue Jeshion's theory of singular thought should be rejected because the central connection she makes between significance and singularity does (...) not hold. However, my argument grants Jeshion's claim that there is a connection between significance and file-thinking. The upshot is not only that we have reason to reject Jeshion's significance constraint on singular thought, but that we have reason to question the connection made by MFC proponents between file-thinking and singularity.

The aim of this paper is to clarify the role of the distinction between belief and opinion in the light of Dennett's intentional stance. In particular, I consider whether the distinction could be used for a defence of the stance from various criticisms. I will then apply the distinction to the so-called `paradoxes of irrationality'. In this context I will propose that we should avoid the postulation of `boundaries' or `gaps' within the mind, and will attempt to show that a (...) useful treatment of the paradoxes can be obtained by revising the rationality assumption.

This paper updates (2017) a previously-presented* model of models, which can be used to clarify discussion and analysis in a variety of disputes and debates, since many such discussions hinge on displaying or implying models about how things are related. Knowing about models does not itself supply any new information about our world, but it might help us to recognize when and how information is being conveyed on these matters, or where possibly it is being obscured. If a claim P (...) is expressed in the context of a certain model, a disagreement about P may actually not be about whether the underlying model is accurate; it could reflect misunderstandings about the model’s assumptions or conventions. Also, in practice, constructed models are rarely fully elaborated for every detail, so misunderstandings can arise from apparent “gaps” in the model. In that case, developing and considering complementary versions of models can sometimes clarify ambiguities. Following the main analysis are several extended Case examples to illustrate the wide applicability of the models approach, for clarifying, if not necessarily “resolving”, numerous debates and issues. For example, a famous “counter example” by Nelson Goodman to a logical model proposed by Carnap is shown to be not as deal-breaking as presumed historically, if only plausible complementary models had been explored. And models sometimes presented as competing in Artificial Intelligence research— “Declarative” versus “Procedural”—can instead be viewed as good examples of “complementary” models. Also reconsidered in this light are some well-known, competing positions, by Russell, Strawson, and Kripke, in the literature regarding names, pointing, definite descriptions and “using” sentences, and so on. All these concepts are locatable within the presently proposed models analysis. Questions such as where “truth” resides (whether in sentences or in uses of sentences) are not settled in this paper; yet, practical questions about how testable claims about the world can be expressed by models are clarified. _* Original version presented at a University of Waterloo Philosophy Colloquium 1984.

Th ere is much controversy surrounding the nature of the relation between fictional individuals and possible individuals. Some have argued that no fictional individual is a possible individual; others have argued that (some) fictional individuals just are (merely) possible individuals. In this paper, I off er further grounds for believing the theory of fictional individuals defended by Amie Thomasson,viz., Artifactualism, by arguing that her view best allows one to make sense of this puzzling relation. More specifically, when we realize that (...) the view allows for an identification of merely possible individuals with fictional individuals, we seethat the utility, and hence the level of credence lent to Artifactualism, is increased. After arguing for this thesis, I respond to three of the most pressing worries. (shrink)

This paper develops an information-sensitive theory of the semantics and probability of conditionals and statements involving epistemic modals. The theory validates a number of principles linking probability and modality, including the principle that the probability of a conditional If A, then C equals the probability of C, updated with A. The theory avoids so-called triviality results, which are standardly taken to show that principles of this sort cannot be validated. To achieve this, we deny that rational agents update their credences (...) via conditionalization. We offer a new rule of update, Hyperconditionalization, which agrees with Conditionalization whenever nonmodal statements are at stake but differs for modal and conditional sentences. (shrink)

Creationism is the conjunction of the following theses: (i) fictional individuals (e.g. Sherlock Holmes) actually exist; (ii) fictional names (e.g., 'Holmes') are at least sometimes genuinely referential; (iii) fictional individuals are the creations of the authors who first wrote (or spoke, etc.) about them. CA Creationism is the conjunction of (i) - (iii) and the following thesis: (iv) fictional individuals are contingently existing abstracta; they are non-concrete artifacts of our world and various other possible worlds. TakashiYagisawa has recently provided a (...) number of arguments designed to show that Creationism is unjustified. I here critically examine three of his challenges to CA Creationism.

A thesis I call the name-based singular thought thesis is part of orthodoxy in contemporary philosophy of mind and language: it holds that taking part in communication involving a proper name puts one in a position to entertain singular thoughts about the name’s referent. I argue, first, that proponents of the NBT thesis have failed to explain the phenomenon of name-based singular thoughts, leaving it mysterious how name-use enables singular thoughts. Second, by outlining the reasoning that makes the NBT thesis (...) seem compelling and showing how it can be resisted, I argue that giving up the NBT thesis is not a cost, but rather a benefit. I do this by providing an expanded conception of understanding for communication involving names, which sheds light on the nature of communication involving names and the structure of name-using practices.

Influential work on proper names, most centrally associated with Kripke (1980), has had a significant influence in the literature on singular thought. The dominant position among contemporary singularists is that we can think singular thoughts about any object we can refer to by name and that, given the range of cases in which it is possible to refer using a name, name use in fact enables singular thought about a name's referent. I call this the extended name-based thought thesis (extended-NBT). (...) This chapter outlines the reasoning and presumptions of theorists who adopt extended NBT, and also outlines a set of reasons to resist it. The piece is distinctive in approaching the question of the relation between names and singular thought by focusing on the function of names and what this function entails (or doesn’t) about the kinds of thoughts (singular or descriptive) we have when we use names to communicate. In short, thinking about the function of names tells against the claim that name-use enables singular thought. (shrink)

Goodman draws together, in this memoir, his explorations of meaning and coincidence, and his lived experiences of chance, and his professional experiences teaching, writing, and consulting about risk. The book opens by describing the author's life-changing encounter with a Zen Buddhist monk in 1977, over a cup of tea. Returning to his beginnings, Goodman recounts his coming-of-age, from participating the 1960’s U.S. protests and Vietnam-War resistance, to finally settling down in Canada. He describes his role in a supporting, (...) silent vigil around Willard Straight Hall at Cornell University, the night after it had been occupied by protestors, and his later application for Conscientious Objector status, following the U.S. draft lottery in 1969. He reflects on the challenges and changes on his road taken, in his career and personal relationships, and in spiritual searches, to share some insights about the seamless nature of chance, and about seeing a Both/And perspective in life that encourages openness to possibilities. -/- .

DOI: 10.1080/00031305.2018.1564697 When the editors of Basic and Applied Social Psychology effectively banned the use of null hypothesis significance testing (NHST) from articles published in their journal, it set off a fire-storm of discussions both supporting the decision and defending the utility of NHST in scientific research. At the heart of NHST is the p-value which is the probability of obtaining an effect equal to or more extreme than the one observed in the sample data, given the null hypothesis and (...) other model assumptions. Although this is conceptually different from the probability of the null hypothesis being true, given the sample, p-values nonetheless can provide evidential information, toward making an inference about a parameter. Applying a 10,000-case simulation described in this article, the authors found that p-values’ inferential signals to either reject or not reject a null hypothesis about the mean (α = 0.05) were consistent for almost 70% of the cases with the parameter’s true location for the sampled-from population. Success increases if a hybrid decision criterion, minimum effect size plus p-value (MESP), is used. Here, rejecting the null also requires the difference of the observed statistic from the exact null to be meaningfully large or practically significant, in the researcher’s judgment and experience. The simulation compares performances of several methods: from p-value and/or effect size-based, to confidence-interval based, under various conditions of true location of the mean, test power, and comparative sizes of the meaningful distance and population variability. For any inference procedure that outputs a binary indicator, like flagging whether a p-value is significant, the output of one single experiment is not sufficient evidence for a definitive conclusion. Yet, if a tool like MESP generates a relatively reliable signal and is used knowledgeably as part of a research process, it can provide useful information. (shrink)

Existing theories of knowledge which deny KK by accepting a Margin for Error (...) principle can be conservatively extended with Fragility. (shrink)

Much attention has been given to the question of ontic vagueness, and the issues usually center around whether certain paradigmatically concrete entities – cats, clouds, mountains, etc. – are vague in the sense of having indeterminate spatial boundaries. In this paper, however, I wish to focus on a way in which some abstracta seem to be locationally vague. To begin, I will briefly cover some territory already covered regarding certain types of “traditional” abstracta and the ways they are currently alleged (...) to be vague. I then wish to discuss two types of “nontraditional” abstracta and the sense in which I think some of these objects are locationally vague. I will next reexamine some of the traditional abstracta and discuss whether any of these objects are locationally vague in the novel way suggested for the nontraditional sorts. I’ll finish by discussing objections, and conclude with some remarks about characterizing the abstract/concrete distinction. (shrink)

Recent advances in natural language processing have given rise to a new kind of AI architecture: the language agent. By repeatedly calling an LLM to perform a variety of cognitive tasks, language agents are able to function autonomously to pursue goals specified in natural language and stored in a human-readable format. Because of their architecture, language agents exhibit behavior that is predictable according to the laws of folk psychology: they function as though they have desires and beliefs, and then make (...) and update plans to pursue their desires given their beliefs. We argue that the rise of language agents significantly reduces the probability of an existential catastrophe due to loss of control over an AGI. This is because the probability of such an existential catastrophe is proportional to the difficulty of aligning AGI systems, and language agents significantly reduce that difficulty. In particular, language agents help to resolve three important issues related to aligning AIs: reward misspecification, goal misgeneralization, and uninterpretability. (shrink)

Intentionalism is the view that the phenomenal character of a conscious experience is wholly determined by, or even reducible to, its representational content. In this essay I put forward a version of intentionalism that allows (though does not require) the reduction of phenomenal character to representational content. Unlike other reductionist theories, however, it does not require the acceptance of phenomenal externalism (the view that phenomenal character does not supervene on the internal state of the subject). According the view offered here, (...) phenomenal characters essentially represent subject-environment relations that are relevant to the possibilities for causal interaction between the subject and the environment; relations of the kind that J. J. Gibson dubbed affordances. I argue for this view chiefly through an examination of spatial perception, though other cases are also considered. The view assumes that a phenomenal character has an essential functional role; though it need not be assumed that a functional role is sufficient for a phenomenal character. (shrink)

A short play wherein three pregnant (previously) anti-abortion men consider the arguments for and against abortion.

One Stoic response to the skeptical indistinguishability argument is that it fails to account for expertise: the Stoics allow that while two similar objects create indistinguishable appearances in the amateur, this is not true of the expert, whose appearances succeed in discriminating the pair. This paper re-examines the motivations for this Stoic response, and argues that it reveals the Stoic claim that, in generating a kataleptic appearance, the perceiver’s mind is active, insofar as it applies concepts matching the perceptual stimulus. (...) I argue that this claim is reflected in the Stoic definition of the kataleptic appearance, and that it respects their more general account of mental representation. I further suggest that, in attributing some activity to the mind in creating each kataleptic appearance, and in claiming that the expert’s mind allows her to form more kataleptic appearances than the amateur, the Stoics draw inspiration from the wax tablet model in Plato’s Theaetetus (190e–196d), where Socrates distinguishes the wise from the ignorant on the basis of how well they match sensory input with its appropriate mental ‘seal’ (σφραγίς).

According to some, free will requires alternative possibilities. But not any old alternative possibility will do. Sometimes, being able to bring about an alternative does not bestow any control on an agent. In order to bestow control, and so be directly relevant qua alternative to grounding the agent's moral responsibility, alternatives need to be robust. Here, I investigate the nature of robust alternatives. I argue that Derk Pereboom's latest robustness criterion is too strong, and I suggest a different criterion based (...) on the idea that what agents need to be able to do is keep open the possibility of securing their blamelessness, rather than needing to directly ensure their own blamelessness at the time of decision.

An extended example illustrating various theories of personal identity and imagining how duplicates would confront the argument that neither of them is identical with the original.

This paper discusses a puzzle, the heart of which is this question: How is it that real individuals can resemble fictional individuals? It seems that any answer given by one who has taken a stand on the ontology of fictional individuals will come with significant drawbacks. An Anti-Realist will have to explain, or explain away, the apparent truth of our positive assertions of resemblance, while a Realist will have to explain how we are to understand resemblance in light of either (...) the further claim that fictional characters are not associated with properties in the same way real individuals are, or that fictional characters are nonexistent or nonactual. I here survey the different Realist and Anti-Realist strategies in hopes that reflection on (mainly the drawbacks of) each will aid those who are curious about ontologies which may include fictionalia.

The foreword to Ken Taylor’s, Referring to the World, contains the text of a Facebook post from the day he completed a draft of the book—also the day of his death. Taylor writes that the book began its life ‘years and years and years ago’ as a short, opinionated introduction to the theory of reference, but became more an introduction to his own views than anything else. He also wrote: -/- The opinions and the supporting arguments have been developed over (...) way too many years, in a series of articles, some of which were written with the book in mind others of which were not. But now they are all gathered together in a single if somewhat sprawling argumentative thread. Maybe some will find them more convincing that way.

Those for whom the book is an introduction to Taylor’s views will find here an outlook on foundational questions in the philosophy of mind and language which is at once sensible and approachable, and also ambitious and insightful. Taylor will continue to be missed and admired by the philosophical community, both as a thinker, and member of the profession. We are lucky to have some of his views gathered together as they are in this book. (shrink)

This paper considers the question of whether chimpanzees possess at least a primitive sense of normativity: i.e., some ability to internalize and enforce social norms—rules governing appropriate and inappropriate behaviour—within their social groups, and to make evaluations of others’ behaviour in light of such norms. A number of scientists and philosophers have argued that such a sense of normativity does exist in chimpanzees and in several other non-human primate and mammalian species. However, the dominant view in the scientific and philosophical (...) literature is that psychological capacities for social norms evolved uniquely in the human lineage, after our last common ancestor with chimpanzees and bonobos. After reviewing some of the existing evidence for normative capacity in chimpanzees, I defend the thesis of chimpanzee normativity against three key theoretical objections that have been presented in the literature, each of which have played a part in motivating the dominant sceptical position. I argue that, while we still have much to learn about the nature and extent of the normative capacities of other animals, there is strong prima facie evidence for social norms and normative evaluation in chimpanzees and the main theoretical objections to chimpanzee normativity are not at all compelling.

LLMs have dramatically improved in capabilities in recent years. This raises the question of whether LLMs could become genuine agents with beliefs and desires. This paper demonstrates an in principle limit to LLM agency, based on their architecture. LLMs are next word predictors: given a string of text, they calculate the probability that various words can come next. LLMs produce outputs that reflect these probabilities. I show that next word predictors are exploitable. If LLMs are prompted to make probabilistic predictions (...) about the world, these predictions are guaranteed to be incoherent, and so Dutch bookable. If LLMs are prompted to make choices over actions, their preferences are guaranteed to be intransitive, and so money pumpable. In short, the problem is that selecting an action based on its potential value is structurally different then selecting the description of an action that is most likely given a prompt: probability cannot be forced into the shape of expected value. The in principle exploitability of LLMs raises doubts about how agential they can become. This exploitability also offers an opportunity for humanity to safely control such AI systems. (shrink)

Many defend the thesis that when someone knows p, they couldn’t easily have been wrong about p. But the notion of easy possibility in play is relatively undertheorized. One structural idea in the literature, the principle of Counterfactual Closure (CC), connects easy possibility with counterfactuals: if it easily could have happened that p, and if p were the case, then q would be the case, it follows that it easily could have happened that q. We first argue that while CC (...) is false, there is a true restriction of it to cases involving counterfactual dependence on a coin flip. The failure of CC falsifies a model where the easy possibilities are counterfactually similar to actuality. Next, we show that extant normality models, where the easy possibilities are the sufficiently normal ones, are incompatible with the restricted CC thesis involving coin flips. Next, we develop a new kind of normality theory that can accommodate the restricted version of CC. This new theory introduces a principle of Counterfactual Contamination, which says roughly that any world is fairly abnormal if at that world very abnormal events counterfactually depend on a coin flip. Finally, we explain why coin flips and other related events have a special status. A central take home lesson is that the correct principle in the vicinity of Safety is importantly normality-theoretic rather than (as it is usually conceived) similarity-theoretic. (shrink)
