Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the a (...) priori. Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality. This major work by a leading philosopher will appeal to philosophers in all areas. This entry contains uncorrected proofs of front matter, chapter 1, and first excursus. (shrink)

Dispositional essentialists argue that physical properties have their causal roles essentially. This is typically taken to mean that physical properties are identical to dispositions. I argue that this is untenable, and that we must instead say that properties bestow dispositions. I explore what it is for a property to have such a role essentially. Dispositional essentialists argue for their view by citing certain epistemological and metaphysical implications, and I appeal to these implications to place desiderata on the concept of essence (...) involved. I argue that the traditional modal theory of essence meets these desiderata, but that the resulting theory wrongly implies that certain dispositions essential to mass are essential to charge, thereby offering a new argument against modal theories of essence. I argue that dispositional essentialism requires a primitive notion of essence, and develop a primitivist theory based on Kit Fine's views. I show that the primitivist theory has all the virtues of the modal alternative, and none of the vices. I develop a novel way of thinking about the relationship between properties, laws and dispositions, and argue that it has distinct advantages over standard dispositional essentialist formulations.

The idea that incompatibilism is intuitive is one of the key motivators for incompatibilism. Not surprisingly, then philosophers who defend incompatibilism often claim that incompatibilism is the natural, commonsense view about free will and moral responsibility (e.g., Pereboom 2001, Kane Journal of Philosophy 96:217–240 1999, Strawson 1986). And a number of recent studies find that people give apparently incompatibilist responses in vignette studies. When participants are presented with a description of a causal deterministic universe, they tend to deny that people (...) are morally responsible in that universe. Although this suggests that people are intuitive incompatibilists, Eddy Nahmias and Dylan Murray, in a recent series of important papers, have developed an important challenge to this interpretation. They argue that people confuse determinism with bypassing, the idea that one’s mental states lack causal efficacy. Murray and Nahmias present new experiments that seem to confirm the bypassing hypothesis. In this paper, we use structural equation modeling to re-examine the issue. We find support instead for an incompatibilist explanation of the bypassing results, i.e., incompatibilist judgments seem to cause bypassing judgments. We hypothesize that this phenomenon occurs because people think of decisions as essentially indeterministic; thus, when confronted with a description of determinism they tend to think that decisions do not even occur. We provide evidence for this in three subsequent studies which show that many participants deny that people make decisions in a deterministic universe; by contrast, most participants tend to allow that people add numbers in a deterministic universe. Together, these studies suggest that bypassing results don’t reflect a confusion, but rather the depth of the incompatibilist intuition. (shrink)

Political philosophers frequently claim that political ideals can provide normative guidance for unjust and otherwise nonideal circumstances. This is mistaken. This paper demonstrates that political ideals contribute nothing to our understanding of the normative principles we should satisfy amidst unjust or otherwise nonideal circumstances.

The principle of alternate possibilities (PAP), making the ability to do otherwise a necessary condition for moral responsibility, is supposed by Harry Frankfurt, John Fischer, and others to succumb to a peculiar kind of counterexample. The paper reviews the main problems with the counterexample that have surfaced over the years, and shows how most can be addressed within the terms of the current debate. But one problem seems ineliminable: because Frankfurt''s example relies on a counterfactual intervener to preclude alternatives to (...) the person''s action, it is not possible for it to preclude all alternatives (intervention that is contingent upon a trigger cannot bring it about that the trigger never occurred). This makes it possible for the determined PAPist to maintain that some pre-intervention deviation is always available to ground moral responsibility. In reply, the critic of PAP can examine all the candidate deviations and argue their irrelevance to moral responsibility (a daunting prospect); or the critic can dispense with counterfactual intervention altogether. The paper pursues the second of these strategies, developing three examples of noncounterfactual intervention in which (i) the agent has no alternatives (and a fortiori no morally relevant alternatives), yet (ii) there is just as much reason to think that the agent is morally responsible as there was in Frankfurt''s original example. The new counterexamples do suffer from one liability, but this is insufficient in the end to repair PAP''s conceptual connection between moral responsibility and alternate possibilities. (shrink)

Actualists of a certain stripe—dispositionalists—hold that metaphysical modality is grounded in the powers of actual things. Roughly: p is possible iff something has, or some things have, the power to bring it about that p. Extant critiques of dispositionalism focus on its material adequacy, and question whether there are enough powers to account for all the possibilities we intuitively want to countenance. For instance, it seems possible that none of the actual contingent particulars ever existed, but it is impossible to (...) explain this by appealing to the powers of some actual thing or things to bring it about. I argue instead that dispositionalism, in the simple form championed by its proponents, is formally inadequate. Dispositionalists interpret the modal operators as simple existential claims about powers, but if we interpret the operators that way, the resulting system of modal logic is too weak to capture metaphysical modality. I argue that we can modify the standard dispositionalist interpretations of the operators to secure formal adequacy, but at the cost of accepting that not all modality is grounded in powers. This, I shall suggest, is not a bad thing—the resulting theory still has powers at its core and has certain attractive features, in addition to formal adequacy, that the standard theory lacks.

In the wake of the non-ideal theory turn in political philosophy, few have paused to ask: Is non-ideal theory a form of ideology? And perhaps even fewer have paused to ask: Is the debate between ideal/non-ideal theorists itself a form of ideology? To the first question, I argue that non-ideal theory is ideological in virtue of the fact that it rules out more utopian ways of theorizing by methodological fiat, and in so doing, risks entrenching an unjust status quo. To (...) the second question, I argue that the debate between ideal/non-ideal theorists is itself a form of ideology, one which serves to reinforce the status quo by convincing political philosophers/theorists that the most pressing problems are problems about what we should think about what we are doing. But this is false. An upshot of my argument is that we ought to abandon the ideal/non-ideal theory debate and address the pressing problems of political philosophy head-on in pluralist fashion, oscillating back and forth between these two modes of theorizing without a decision procedure to tell us when we should take up one perspective or the other.

Current controversies about knowledge integration reflect conflicting ideas of what it means to “take Indigenous knowledge seriously”. While there is increased interest in integrating Indigenous and Western scientific knowledge in various disciplines such as anthropology and ethnobiology, integration projects are often accused of recognizing Indigenous knowledge only insofar as it is useful for Western scientists. The aim of this article is to use tools from philosophy of science to develop a model of both successful integration and integration failures. On the (...) one hand, I argue that cross-cultural recognition of property clusters leads to an ontological overlap that makes knowledge integration often epistemically productive and socially useful. On the other hand, I argue that knowledge integration is limited by ontological divergence. Adequate models of Indigenous knowledge will therefore have to take integration failures seriously and I argue that integration efforts need to be complemented by a political notion of ontological self-determination.

This paper replies to objections from perceptual distortion against the representationalist thesis that the phenomenal characters of experiences supervene on their intentional contents. It has been argued that some pairs of distorted and undistorted experiences share contents without sharing phenomenal characters, which is incompatible with the supervenience thesis. In reply, I suggest that such cases are not counterexamples to the representationalist thesis because the contents of distorted experiences are always impoverished in some way compared to those of normal experiences. This (...) can be shown by considering limit cases of perceptual distortion, for example, maximally blurry experiences, which manifestly lack details present in clear experiences. I argue that since there is no reasonable way to draw the line between distorted experiences that have degraded content and distorted experiences that do not, we should allow that an increase in distortion is always accompanied by a change in content. This applies to perceptual distortions due to blur, double vision, perspective, and illumination conditions. (shrink)

The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has the (...) effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

People attribute purposes in both mundane and profound ways—such as when thinking about the purpose of a knife and the purpose of a life. In three studies (total N = 13,720 observations from N = 3,430 participants), we tested whether these seemingly very different forms of purpose attributions might actually involve the same cognitive processes. We examined the impacts of four factors on purpose attributions in six domains (artifacts, social institutions, animals, body parts, sacred objects, and human lives). Study 1 (...) manipulated what items in each domain were originally created for (original design) and how people currently use them (present practice). Study 2 manipulated whether items are good at achieving a goal (effectiveness) and whether the goal itself is good (morality). We found effects of each factor in every domain. However, whereas morality and effectiveness had remarkably similar effects across domains, the effects of original design and present practice differed substantially. Finally, Study 3 revealed that, within domains, the effects of original design and present practice depend on which entities design and use items. These results reveal striking similarities in purpose attributions across domains and suggest that certain entities are treated as authorities over the purposes of particular items. (shrink)

The proposal I offer attempts to remedy the inadequacies of exclusive focus on well-being for moral purposes. The proposal is this: We should allow the agent to decide for herself where she wants to throw the weight that is her due in moral reflection, with the proviso that she understands the way that her weight will be aggregated with others in reaching a moral outcome. I will call this the "autonomy principle." The autonomy principle, I claim, provides the consequentialist's best (...) prospect for taking people into account morally in a way that they endorse.

A discussion of three central ideas in action theory; trying to act, doing or acting, one's action causing further consequences.

This book concerns the foundations of epistemic modality and hyperintensionality and their applications to the philosophy of mathematics. David Elohim examines the nature of epistemic modality, when the modal operator is interpreted as concerning both apriority and conceivability, as well as states of knowledge and belief. The book demonstrates how epistemic modality and hyperintensionality relate to the computational theory of mind; metaphysical modality and hyperintensionality; the types of mathematical modality and hyperintensionality; to the epistemic status of large cardinal axioms, (...) undecidable propositions, and abstraction principles in the philosophy of mathematics; to the modal and hyperintensional profiles of the logic of rational intuition; and to the types of intention, when the latter is interpreted as a hyperintensional mental state. Chapter \textbf{2} argues for a novel type of expressivism based on the duality between the categories of coalgebras and algebras, and argues that the duality permits of the reconciliation between modal and hyperintensional cognitivism and modal and hyperintensional expressivism. Elohim develops a novel, topic-sensitive truthmaker semantics for dynamic epistemic logic, and develops a novel, dynamic two-dimensional semantics grounded in two-dimensional hyperintensional Turing machines. Chapter \textbf{3} provides an abstraction principle for two-dimensional (hyper-)intensions. Chapter \textbf{4} advances a topic-sensitive two-dimensional truthmaker semantics, and provides three novel interpretations of the framework along with the epistemic and metasemantic. Chapter \textbf{5} applies the fixed points of the modal $\mu$-calculus in order to account for the iteration of epistemic states in a single agent, by contrast to availing of modal axiom 4 (i.e. the KK principle). The fixed point operators in the modal $\mu$-calculus are rendered hyperintensional, which yields the first hyperintensional construal of the modal $\mu$-calculus in the literature and the first application of the calculus to the iteration of epistemic states in a single agent instead of the common knowledge of a group of agents. Chapter \textbf{6} advances a solution to the Julius Caesar problem based on Fine's `criterial' identity conditions which incorporate conditions on essentiality and grounding. Chapter \textbf{7} provides a ground-theoretic regimentation of the proposals in the metaphysics of consciousness and examines its bearing on the two-dimensional conceivability argument against physicalism. The topic-sensitive epistemic two-dimensional truthmaker semantics developed in chapters \textbf{2} and \textbf{4} is availed of in order for epistemic states to be a guide to metaphysical states in the hyperintensional setting. -/- Chapters \textbf{8-12} provide cases demonstrating how the two-dimensional hyperintensions of hyperintensional, i.e. topic-sensitive epistemic two-dimensional truthmaker, semantics, solve the access problem in the epistemology of mathematics. Chapter \textbf{8} examines the interaction between Elohim's hyperintensional semantics and the axioms of epistemic set theory, large cardinal axioms, the Epistemic Church-Turing Thesis, the modal axioms governing the modal profile of $\Omega$-logic, Orey sentences such as the Generalized Continuum Hypothesis, and absolute decidability. These results yield inter alia the first hyperintensional Epistemic Church-Turing Thesis and hyperintensional epistemic set theories in the literature. Chapter \textbf{9} examines the modal and hyperintensional commitments of abstractionism, in particular necessitism, and epistemic hyperintensionality, epistemic utility theory, and the epistemology of abstraction. Elohim countenances a hyperintensional semantics for novel epistemic abstractionist modalities. Elohim suggests, too, that higher observational type theory can be applied to first-order abstraction principles in order to make first-order abstraction principles recursively enumerable, i.e. Turing machine computable, and that the truth of the first-order abstraction principle for two-dimensional hyperintensions is grounded in its being possibly recursively enumerable and the machine being physically implementable. Chapter \textbf{10} examines the philosophical significance of hyperintensional $\Omega$-logic in set theory and discusses the hyperintensionality of metamathematics. Chapter \textbf{11} provides a modal logic for rational intuition and provides a hyperintensional semantics. Chapter \textbf{12} avails of modal coalgebras to interpret the defining properties of indefinite extensibility, and avails of hyperintensional epistemic two-dimensional semantics in order to account for the interaction between interpretational and objective modalities and the truthmakers thereof. This yields the first hyperintensional category theory in the literature. Elohim invents a new mathematical trick in which first-order structures are treated as categories, and Vopenka's principle can be satisfied because of the elementary embeddings between the categories and generate Vopenka cardinals in the category of Set in category theory. Chapter \textbf{13} examines modal responses to the alethic paradoxes. Elohim provides a counter-example to epistemic closure for logical deduction. Chapter \textbf{14} examines, finally, the modal and hyperintensional semantics for the different types of intention and the relation of the latter to evidential decision theory. (shrink)

One strategy in recent discussions of theological fatalism is to draw on Harry Frankfurt’s famous counterexamples to the principle of alternate possibilities (PAP) to defend human freedom from divine foreknowledge. For those who endorse this line, “Frankfurt counterexamples” are supposed to show that PAP is false, and this conclusion is then extended to the foreknowledge case. This makes it critical to determine whether Frankfurt counterexamples perform as advertised, an issue recently debated in this journal via a pair of articles by (...) David Widerker and John Martin Fischer. I suggest that this debate can be avoided: divine foreknowledge is itself aparadigmatic counterexample to PAP, requiring no support from suspect Frankfurt counterexamples. (shrink)

I discuss Gheaus's (2013) argument against the claim that the requirements of justice are not constrained by feasibility concerns. I show that the general strategy exemplified by this argument is not only dialectically puzzling, but also imposes a heavy cost on theories of justice -- puzzling because it simply sidesteps a presupposition of any plausible formulation of the so-called "feasibility requirement"; costly because it it deprives justice of its normative implications for action. I also show that Gheaus's attempt to recover (...) this normative force presupposes an epistemic dimension to the feasibility requirement that most proponents of that requirement would reject.

Many political philosophers hold the Feasible Alternatives Principle (FAP): justice demands that we implement some reform of international institutions P only if P is feasible and P improves upon the status quo from the standpoint of justice. The FAP implies that any argument for a moral requirement to implement P must incorporate claims whose content pertains to the causal processes that explain the current state of affairs. Yet, philosophers routinely neglect the need to attend to actual causal processes. This undermines (...) their arguments concerning moral requirements to reform international institutions. The upshot is that philosophers’ arguments must engage in causal analysis to a greater extent than is typical. -/- [Supplement: Handout available at http://db.tt/fyuVW3Xv]. (shrink)

Frankfurt cases are purported counterexamples to the Principle of Alternative Possibilities, which implies that we are not morally responsible for unavoidable actions. A major permutation of the counterexample strategy features buffered alternatives; this permutation is designed to overcome an influential defense of the Principle of Alternative Possibilities. Here we defend the buffering strategy against two recent objections, both of which stress the timing of an agent’s decision. We argue that attributions of moral responsibility aren’t time-sensitive in the way the objectors (...) suppose. We then turn to the crucial question of when an action is relevantly avoidable—when, in the parlance of the literature, an alternative possibility is robust. We call attention to two plausible tests for robustness that merit further consideration, showing that the agents in buffered Frankfurt cases don’t pass these tests, despite being morally responsible for their actions.

What is the function of morality—what is it all about? What is the basis of morality—what explains our moral agency and patiency? This essay defends a unique Kantian answer to these questions. Morality is about securing our independence from each other by giving each other equal discretion over whether and how we interact. The basis of our moral agency and patiency is practical reason. The first half addresses objections that this account cannot explain the moral patiency of beings who are (...) not also moral agents such as infantile, elderly, and infirm human beings and the other animals who are not moral agents. The second half argues that this account is preferable, on grounds of consistency with the basic Kantian account of the function and content of morality, to the familiar account of our moral patiency, popular especially though not exclusively with contemporary Kantians, in terms of the value of humanity.

We describe a strategy for integration of data that is based on the idea of semantic enhancement. The strategy promises a number of benefits: it can be applied incrementally; it creates minimal barriers to the incorporation of new data into the semantically enhanced system; it preserves the existing data (including any existing data-semantics) in their original form (thus all provenance information is retained, and no heavy preprocessing is required); and it embraces the full spectrum of data sources, types, models, and (...) modalities (including text, images, audio, and signals). The result of applying this strategy to a given body of data is an evolving Dataspace that allows the application of a variety of integration and analytic processes to diverse data contents. We conceive semantic enhancement (SE) as a lightweight and flexible process that leverages the richness of the structured contents of the Dataspace without adding storage and processing burdens to what, in the intelligence domain, will be an already storage- and processing-heavy starting point. SE works not by changing the data to which it is applied, but rather by adding an extra semantic layer to this data. We sketch how the semantic enhancement approach can be applied consistently and in cumulative fashion to new data and data-models that enter the Dataspace. (shrink)

We have a mentalistic view of objects. This is due to the interdependence of folk psychology and folk physics, where these are interconnected by what I call Teleological Commingling. When considering events that don’t involve agents, we naturally default to tracking intentions, goal-directed processes, despite the fact that agents aren’t involved. We have a deep-seated intentionality bias which is the result of the pervasive detection of agency cues, such as order or non-randomness. And this gives rise to the Agentive Worldview: (...) we view nature as a whole as being infused with agency and purpose. Teleological Commingling and the Agentive Worldview it gives rise to are at the core of our conception of objects. I maintain that the ordinary view of material objects is rooted in an implicit, false theory. It should be given no weight in metaphysical debates about the nature of material objects. And this problematizes the central methodological assumption that metaphysical theories of material objects should be beholden to common sense. (shrink)

In Human Nature and the Limits of Political Philosophy, I argued that justice might require things of people that they cannot bring themselves to do. A central step was to argue that this does not entail an inability to ‘do’ the putatively required thing. David Wiens challenges that argument of mine, and this piece is my reply.

Working within the broad lines of general consensus that mark out the core features of John Stuart Mill’s (1806–1873) logic, as set forth in his A System of Logic (1843–1872), this chapter provides an introduction to Mill’s logical theory by reviewing his position on the relationship between induction and deduction, and the role of general premises and principles in reasoning. Locating induction, understood as a kind of analogical reasoning from particulars to particulars, as the basic form of inference that is (...) both free-standing and the sole load-bearing structure in Mill’s logic, the foundations of Mill’s logical system are briefly inspected. Several naturalistic features are identified, including its subject matter, human reasoning, its empiricism, which requires that only particular, experiential claims can function as basic reasons, and its ultimate foundations in ‘spontaneous’ inference. The chapter concludes by comparing Mill’s naturalized logic to Russell’s (1907) regressive method for identifying the premises of mathematics. (shrink)

Corruptionism is the view that following physical death, the human being ceases to exist but their soul persists in the afterlife. Survivalism holds that both the human being and their soul persist in the afterlife, as distinct entities, with the soul constituting the human. Each position has its defenders, most of whom appeal both to metaphysical considerations and to the authority of St Thomas Aquinas. Corruptionists claim that survivalism violates a basic principle of any plausible mereology, while survivalists tend to (...) reject the principle, though without as much detail as one would like. In this paper I examine both the key exegetical issues and the mereological question, arguing that Aquinas cannot be shown to have supported the principle in question, and that the principle should be rejected on independent grounds. If correct, some key planks in support of survivalism are established, with others to await further examination. (shrink)

This paper discusses the so-called non-interference assumption (NIA) grounding causal inference in trials in both medicine and the social sciences. It states that for each participant in the experiment, the value of the potential outcome depends only upon whether she or he gets the treatment. Drawing on methodological discussion in clinical trials and laboratory experiments in economics, I defend the necessity of partial forms of blinding as a warrant of the NIA, to control the participants’ expectations and their strategic interactions (...) with the experimenter.

Is the exemplar of modern ethical theory estranged from their intimates because the motive of duty dominates their motivational psychology? While this challenge against modern ethical theory is familiar, I argue that with respect to a certain strand of Kantian ethical theory, it does not so much as make sense. I explain the content and functional role of the motive of duty in the psychology of the moral exemplar, stressing in particular how that motive shapes and informs the content of (...) others, including those characteristic of intimacy. I argue that to the extent that a subject does not integrate their motive of duty with their other motives, their moral and intimate relationships are compromised, and on the same grounds, because intimate relationships are interpersonal relationships and the motive of duty just is the motive to respect another person as a separate person.

Debiasing procedures are experimental methods aimed at correcting errors arising from the cognitive biases of the experimenter. We discuss two of these methods, the predesignation rule and randomization, showing to what extent they are open to the experimenter’s regress: there is no metarule to prove that, after implementing the procedure, the experimental data are actually free from biases. We claim that, from a contractarian perspective, these procedures are nonetheless defensible since they provide a warrant of the impartiality of the experiment: (...) we only need proof that the result has not been intentionally manipulated for prima facie acceptance.

Recent years have seen a surge in online collaboration between experts and amateurs on scientific research. In this article, we analyse the epistemological implications of these crowdsourced projects, with a focus on Zooniverse, the world’s largest citizen science web portal. We use quantitative methods to evaluate the platform’s success in producing large volumes of observation statements and high impact scientific discoveries relative to more conventional means of data processing. Through empirical evidence, Bayesian reasoning, and conceptual analysis, we show how information (...) and communication technologies enhance the reliability, scalability, and connectivity of crowdsourced e-research, giving online citizen science projects powerful epistemic advantages over more traditional modes of scientific investigation. These results highlight the essential role played by technologically mediated social interaction in contemporary knowledge production. We conclude by calling for an explicitly sociotechnical turn in the philosophy of science that combines insights from statistics and logic to analyse the latest developments in scientific research.

In proof-theoretic semantics, meaning is based on inference. It may be seen as the mathematical expression of the inferentialist interpretation of logic. Much recent work has focused on base-extension semantics, in which the validity of formulas is given by an inductive definition generated by provability in a ‘base’ of atomic rules. Base-extension semantics for classical and intuitionistic propositional logic have been explored by several authors. In this paper, we develop base-extension semantics for the classical propositional modal systems K, KT , (...) K4, and S4, with □ as the primary modal operator. We establish appropriate soundness and completeness theorems and establish the duality between □ and a natural presentation of ♢. We also show that our semantics is in its current form not complete with respect to euclidean modal logics. Our formulation makes essential use of relational structures on bases. (shrink)

Although some ancient sources relate Parmenides to the religious doctrine of fate, this concept is not usually prominent in the scholarly presentation of the Eleatic thinker. Here, we offer a tentative interpretation of the notion of necessity in Parmenides’ poem, as a peculiar philosophical understanding of the presence of fate in reality. Necessity, divinised by Parmenides, implies that all things are bound together by the chains of fate. Therefore, his philosophical proposal consists in understanding this unity of reality originated by (...) the connexion of fatal necessity. However, this presence of fate in all things is not bad news, but also means that everything is connected by Love. (shrink)

The paper that follows continues a discussion with Tomis Kapitan in the pages of this journal over the compatibility of divine agency with divine foreknowledge. I had earlier argued against two premises in Kapitan's case for omniscient impotence: (i) that intentionally A-ing presupposes prior acquisition of the intention to A, and (ii) that acquiring the intention to A presupposes prior ignorance whether one will A. In response to my criticisms, Kapitan has recently offered new defences for these two premises. I (...) show in reply why neither defence succeeds in rehabilitating the case against omniscient agency.

Traditionally, the investigation of truth has been anchored in a priori reasoning. Cognitive science deviates from this tradition by adding empirical data on how people understand and use concepts. Building on psychophysics and machine learning methods, we introduce conceptual scaling, an approach to map people's understanding of abstract concepts. This approach, allows computing participant-specific conceptual maps from obtained ordinal comparison data, thereby quantifying perceived similarities among abstract concepts. Using this approach, we investigated individual's alignment with philosophical theories on truth and (...) the predictive capacity of conceptual maps. The obtained results indicated that, while people's understanding of truth is multifaceted and encapsulates notions of coherence and authenticity, alignment is best for the correspondence theory of truth. Furthermore, conceptual maps allowed predicting individual outcomes with an accuracy of roughly 70%. This research demonstrates that conceptual scaling offers accurate descriptions of individual's understanding of abstract concepts, behavioral predictions, and quantification of alignment with theoretical perspectives.

The generative AI boom is unleashing its minions. Enterprise software vendors have rolled out legions of automated assistants that use large language model (LLM) technology, such as ChatGPT, to offer users helpful suggestions or to execute simple tasks.

In this article, we explain how that leads to the risk that users' ethical competence may degrade over time — and what to do about it.

The late Middle Ages witnessed a recapitulation of medieval reflection on beauty. Jean Gerson is an important representative of these philosophical and theological contributions, although he has been largely neglected up to this time. A first dimension of his ideas on beauty is the incorporation of beauty (pulchrum) into the number of transcendentals, i.e., the concepts “convertible” with the notion of being (ens), that is, unity, truth, and goodness (unum, verum and bonum). This article revisits Monica Calma’s study on Gerson’s (...) theory of beauty and suggests new hypothetical sources that may have inspired this aspect of his thought. The second aspect emphasised here is Gerson’s classification of beauty, which entails some similarities to the one of Ulrich of Strasbourg, but also differs from it. Moreover, its incorporation of a division entirely devoted to artistic beauty is highly remarkable. (shrink)

A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model that specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. -/- One of the main difficulties with consciousness is that we lack a language in which to formulate illuminating (...) generalizations about it. Philosophers and scientists talk about "what it’s like", sensations, feelings, and perceptual states such as seeing and hearing. This language does not allow a precise articulation of the internal structures of conscious states and their inter-relations. It is inadequate to capture relations of the kind we are looking for between conscious states and physical states. -/- In this thesis I refine and defend a theory of consciousness which promises to solve this regimentation problem: the representational theory of consciousness. I argue that the representational theory can solve the regimentation problem and smooth out other important obstacles to a fruitful study of consciousness. I also make a case for the theory independently of its payoffs, and I discuss the leading opposing theories at some length. (shrink)

Phenomenology is based on a doctrine of evidence that accords a crucial role to the human capacity to conceptualise or ‘intuit’ features of their experience. However, there are grounds for holding that some experiential entities to which phenomenologists are committed must be intuition-transcendent or ‘dark’. Examples of dark phenomenology include the very fine-grained perceptual discriminations which Thomas Metzinger calls ‘Raffman Qualia’ and, crucially, the structure of temporal awareness. It can be argued, on this basis, that phenomenology is in much the (...) same epistemological relationship to its own subject matter as descriptive (i.e. ‘phenomenological’) physics or biology are to physical and biological reality: phenomenology cannot tell us what phenomenology is really ‘about’. This does not mean we should abjure phenomenology. It implies, rather, that the domain of phenomenology is not the province of a self-standing, autonomous discipline but must be investigated with any empirically fruitful techniques that are open to us (e.g. computational neuroscience, artificial intelligence, etc.). Finally, it entails that while a naturalized phenomenology should be retained as a descriptive, empirical method, it should not be accorded transcendental authority. (shrink)

Friendship is a notion that runs through the thought of different ancient philosophers and has the peculiar characteristic of being held in high esteem almost unanimously by all. Although there are earlier precedents, for Socrates friendship takes on great importance and his disciple Plato provides deep reflections on the subject, linking friendship with transcendence. However, the pages of Aristotle's 'Nicomachean Ethics' on this subject are undoubtedly the most influential for posterity. For him, friendship has many variants, although he privileges over (...) all of them friendship between equals and founded on ethical character. Only complete moral integrity guarantees that the love between friends consists of a genuine appreciation for the person of the other and not for something different from it. After Aristotle, Cicero's treatise 'Lellius' or 'On Friendship' stands out. Despite taking up several appreciations of Aristotle, Cicero is original and corrects some of his ideas, giving priority to the strength of mutual love over the preconditions of friends. Moreover, he gives a prominent place to trust ('fides') in their relationship. Finally, Seneca frames friendship within his ethical conception, subordinating love for the friend to the moral development of the philosopher. (shrink)

Humour is worthy of serious ethical consideration. However, it is often taken far too seriously. In this paper, it is argued that while humour is sometimes unethical, it is wrong much less often than many people think. Non-contextual criticisms, which claim that certain kinds of humour are always wrong, are rejected. Contextual criticisms, which take issue with particular instances of humour rather than types of humour, are more promising. However, it is common to overstate the number of contexts in which (...) humour is wrong. Various mistakes of this kind are highlighted and cautioned against. (shrink)

Sacrificial dilemmas such as the trolley problem play an important role in experimental philosophy (x-phi). But it is increasingly argued that, since we are not likely to encounter runaway trolleys in our daily life, the usefulness of such thought experiments for understanding moral judgments in more ecologically valid contexts may be limited. However, similar sacrificial dilemmas are experienced in real life by animal research decision makers. As part of their job, they must make decisions about the suffering, and often the (...) death, of many non-human animals. For this reason, a context-specific investigation of so-called “3R dilemmas” (i.e., dilemmas where there is a conflict between the principles of replacement, reduction, and refinement of the use of animals in research) is essential to improve the situation of both non-human animals and human stakeholders. An approach well suited for such investigation is experimental philosophical bioethics (“bioxphi”), which draws on methods similar to x-phi to probe more realistic, practical scenarios with an eye to informing normative debates and ethical policy. In this article, we argue for a need to investigate 3R dilemmas among professional decision-makers using the tools of bioxphi. In a first step, we define 3R dilemmas and discuss previous investigations of professionals’ attitudes in such cases. In a second step, we show how bioxphi is a promising method to investigate the whys and hows of professional decision-making in 3R dilemmas. In a last step, we provide a bioxphi template for 3R dilemmas, give recommendations on its use, explore the normative relevance of data collected by such means, and discuss important limitations.

Se ofrece una interpretación de la filosofía política de María Zambrano desde el sufismo deIbnʿArabī. Primero, explicaremos tres nociones centrales en la obra del Šayḫ, como la doble fidelidad a la dimensión de la «incomparabilidad» (tanzīh) y de la «similaridad» (tašbīh), la «nueva creación» (ḫalq al-ǧadīd) y el «hombre perfecto» (insān al-kāmil). Después, trataremos algunos de los textos más políticos de Zambrano, como Horizonte del liberalismo(1929), Isla de Puerto Rico (1940), «Martí, camino de su muerte» (1953) y Persona y democracia (...) (1958). Según veremos, el marco ontológico, epistemológico y antropológicodel maestro andalusí permite ahondar en el sentido místico del discurso político zambraniano. (shrink)

In our paper, we argue for three necessary conditions for morally permissible animal research: (1) an assertion (or expectation) of sufficient net benefit, (2) a worthwhile-life condition, and (3) a no-unnecessary-harm/qualified-basic-needs condition. We argue that these conditions are necessary, without taking a position on whether they are jointly sufficient. In their excellent commentary on our paper, Matthias Eggel, Carolyn Neuhaus, and Herwig Grimm (hereafter, the authors) argue for a friendly amendment to one of our three conditions. In particular, they argue (...) for replacing the first condition—expectation of sufficient net benefit (ESNB)—with an expectation of knowledge production (EKP). In this reply, we will explain why we are open to this proposed amendment, but not yet convinced. (shrink)

An experiment was performed to test the hypothesis that people sometimes take physical actions to make themselves more effective problem solvers. The task was to generate all possible words that could be formed from seven Scrabble letters. In one condition, participants could use their hands to manipulate the letters, and in another condition, they could not. Results show that more words were generated with physical manipulation than without. However, an interaction was obtained between the physical manipulation conditions and the specific (...) letter sets chosen, indicating that physical manipulation helps more for generating words in some circumstances than in others. Overall, our findings can be explained in terms of an interactive search process in which external, physical activity effectively complements internal, cognitive activity. Within this framework, the interaction can be explained in terms of the relative difficulty of generating words from the letters given in the different sets. (shrink)

This paper seeks to rehabilitate St. Augustine’s widely dismissed response to the alleged incompatibility of divine foreknowledge and free will. This requires taking a fresh look at his analysis in On Free Choice of the Will, and arguing its relevance to the current debate. Along the way, mistaken interpretations of Augustine are rebutted, his real solution is developed and defended, a reason for his not anticipating Boethius’s a temporalist solution is suggested, a favorable comparison with Ockham is made, rival solutions (...) are rejected, and the aporetic nature of the problem is explained.

Debates on the practical relevance of ideal theory revolve around Sen's metaphor of navigating a mountainous landscape. In *The Tyranny of the Ideal*, Gerald Gaus presents the most thorough articulation of this metaphor to date. His detailed exploration yields new insight on central issues in existing debates, as well as a fruitful medium for exploring important limitations on our ability to map the space of social possibilities. Yet Gaus's heavy reliance on the navigation metaphor obscures questions about the reasoning by (...) which ideal theories are justified. As a result, Gaus fails to notice the ways in which his theory of the Open Society resembles the ideal theories he aims to dismiss. Ironically, Gaus winds up neglecting the ways in which the Open Society might tyrannize our efforts to realize greater justice. (This article is part of a symposium on Gaus's *The Tyranny of the Ideal*.). (shrink)

Philosophy is inserted as a pedagogical novelty, a sort of renewal of the preparation of young people for adult life. However, what begins as an educational reform ends up representing a genuine intellectual approach: the formulation of scientific knowledge emerges from it. Philosophy goes beyond the originally narrow boundaries of paideia, understood as education of the young, to become a way of life also for adults. However, this does not prevent Greek and Roman philosophy can be understood as a community (...) of life, if not always between “teachers and disciples”, at least between “lovers of knowledge”, philosophers, who are also among themselves lovers, i.e. “friends”. For these reasons, these pages begin with a brief consideration of the Greek paideia, from traditional religion to philosophy. Second, the paper exposes the important imitative character of Greek education inherited by philosophy. Third, the article pays attention to a privileged context for the development of imitation, the philosophical friendship, the discipleship among philosophers itself. In friendship we will find a context that overcomes some of the limitations posed by education founded on imitation. (shrink)

In our daily lives, as in science and in all other domains, we encounter huge numbers of dispositions (tendencies, potentials, powers) which are realized in processes such as sneezing, sweating, shedding, melting. Among this plethora of what we can think of as ‘mere dispositions’ is a subset of dispositions in whose realizations we have an interest – a car responding well when driven on ice, a rabbit’s lungs responding well when it is chased by a wolf, and so on. We (...) call the latter ‘capabilities’ and we attempt to provide an ontological account of what capabilities are that is of sufficient generality to serve a variety of purposes, for example by providing a useful extension to ontology-based research in areas where capabilities data are being collected in siloed fashion.

In various of my writings, both in Philosophical Studies and elsewhere, I have argued that an account of trying sentences is available that does not require quantification over alleged attempts or tryings. In particular, adverbial modification in such sentences can be dealt with, without quantification over any such particulars. In ‘Attempts’, Jonathan D. Payton (Payton, 2021) has sought to dispute my claim. In this paper, I consider his claims and reply to them. I believe that my account withstands such scrutiny.

Much of a culture’s history – its knowledge, capacity, style, and mode of material engagement – is encoded and transmitted in its artifacts. Artifacts crystallize practice; they are a type of meme reservoir that people interpret though interaction. So, in a sense, artifacts transmit cognition; they help to transmit practice across generations, shaping the ways people engage and encounter their world. So runs one argument.
