As humans, we use the power of thinking to make scientific discoveries, develop technologies, manage social interactions, and transmit knowledge to the next generations. With the ability to think, we can trace back and discover the origin of the universe, the natural world, and ourselves. The content of this book, Mindsponge Theory, is part of that discovery process. -/- Product Details -/- Publisher ‏ : ‎ Walter de Gruyter (December 6, 2022) Publication date ‏ : ‎ December 6, 2022 (...)

There are many views about the structure of concepts, a plausible one of which is the theory-theory. Though this view is plausible for concrete concepts, it is unclear that it would work for abstract concepts, and then for moral concepts. The goal of this paper is to provide a plausible theory-theory account for moral concepts and show that it is supported by results in the moral psychology literature. Such studies in moral psychology do not explicitly contend (...) for the theory-theory of moral concepts, but I demonstrate that they actually do provide evidence for the use of theory knowledge at times in moral categorization and decision-making. In philosophy of cognitive science, I newly show that there is evidence that the theory-theory does apply to some moral concepts. (shrink)

Alison Gopnik and Andrew Meltzoff have argued for a view they call the ‘theory theory’: theory change in science and children are similar. While their version of the theory theory has been criticized for depending on a number of disputed claims, we argue that there is a fundamental problem which is much more basic: the theory theory is multiply ambiguous. We show that it might be claiming that a similarity holds between theory (...) change in children and (i) individual scientists, (ii) a rational reconstruction of a Superscientist, or (iii) the scientific community. We argue that (i) is false, (ii) is non-empirical (which is problematic since the theory theory is supposed to be a bold empirical hypothesis), and (iii) is either false or doesn’t make enough sense to have a truth-value. We conclude that the theory theory is an interesting failure. Its failure points the way to a full, empirical picture of scientific development, one that marries a concern with the social dynamics of science to a psychological theory of scientific cognition.

If the world itself is metaphysically indeterminate in a specified respect, what follows? In this paper, we develop a theory of metaphysical indeterminacy answering this question.

This chapter surveys hybrid theories of well-being. It also discusses some criticisms, and suggests some new directions that philosophical discussion of hybrid theories might take.

This paper argues that we should replace the common classification of theories of welfare into the categories of hedonism, desire theories, and objective list theories. The tripartite classification is objectionable because it is unduly narrow and it is confusing: it excludes theories of welfare that are worthy of discussion, and it obscures important distinctions. In its place, the paper proposes two independent classifications corresponding to a distinction emphasised by Roger Crisp: a four-category classification of enumerative theories (about which items constitute (...) welfare), and a four-category classification of explanatory theories (about why these items constitute welfare).

The proof theory of many-valued systems has not been investigated to an extent comparable to the work done on axiomatizatbility of many-valued logics. Proof theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. One particular method for systematically obtaining calculi for all finite-valued logics was invented independently by several researchers, with slight variations in design and presentation. The main aim of this report is to develop the proof theory of (...) finite-valued first order logics in a general way, and to present some of the more important results in this area. In Systems covered are the resolution calculus, sequent calculus, tableaux, and natural deduction. This report is actually a template, from which all results can be specialized to particular logics.

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the (...) normative principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing (...) the truth of certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

The received view in physicalist philosophy of mind assumes that causation can only take place at the physical domain and that the physical domain is causally closed. It is often thought that this leaves no room for mental states qua mental to have a causal influence upon the physical domain, leading to epiphenomenalism and the problem of mental causation. However, in recent philosophy of causation there has been growing interest in a line of thought that can be called causal antifundamentalism: (...) causal notions cannot play a role in physics, because the fundamental laws of physics are radically different from causal laws. Causal anti-fundamentalism seems to challenge the received view in physicalist philosophy of mind and thus raises the possibility of there being genuine mental causation after all. This paper argues that while causal anti-fundamentalism provides a possible route to mental causation, we have reasons to think that it is incorrect. Does this mean that we have to accept the received view and give up the hope of genuine mental causation? I will suggest that the ontological interpretation of quantum theory provides us both with a view about the nature of causality in fundamental physics, as well as a view how genuine mental causation can be compatible with our fundamental (quantum) physical ontology.

Here is a definition of knowledge: for you to know a proposition p is for you to have an outright belief in p that is correct precisely because it manifests the virtue of rationality. This definition resembles Ernest Sosa’s “virtue theory”, except that on this definition, the only virtue that must be manifested in all instances of knowledge is rationality, and no reductive account of rationality is attempted—rationality is assumed to be an irreducibly normative notion. This definition is compatible (...) with “internalism” about rationality, and with a form of “pragmatic encroachment” on the conditions of rational outright belief. An interpretation is given of this definition, and especially of the sense of ’because’ that it involves. On this interpretation, this definition entails that both safety and adherence are necessary conditions on knowledge; it supports a kind of contextualism about terms like ‘knowledge’; and it provides resources to defend safety, adherence, and contextualism, against some recent objections.

Set-theoretic and category-theoretic foundations represent different perspectives on mathematical subject matter. In particular, category-theoretic language focusses on properties that can be determined up to isomorphism within a category, whereas set theory admits of properties determined by the internal structure of the membership relation. Various objections have been raised against this aspect of set theory in the category-theoretic literature. In this article, we advocate a methodological pluralism concerning the two foundational languages, and provide a theory that fruitfully interrelates (...) a `structural' perspective to a set-theoretic one. We present a set-theoretic system that is able to talk about structures more naturally, and argue that it provides an important perspective on plausibly structural properties such as cardinality. We conclude the language of set theory can provide useful information about the notion of mathematical structure. (shrink)

Our purpose in this article is to identify and suggest resolution for two core problematics of grounded theory. First, while grounded theory provides transparency to one part of the conceptualization process, where codes emerge directly from the data, it provides no such systematic or transparent way for gaining insight into the conceptual relationships between discovered codes. Producing a grounded theory depends not only on the definition of conceptual pieces, but the delineation of a relationship between at least (...) two of those pieces. Second, the conceptualization process of grounded theory is done in hierarchical fashion, where individual codes emerge from the data but then are used to generate insight into more general concepts and thematic statements. But various works on grounded theory have failed to provide any systematic way of using data specific levels of scale (the codes) to gain insight into more macro levels of scale (concepts and themes). We offer fractal concept analysis as a means of resolving both of these issues. By using a logic structure generator, fractal concept analysis delineates self-similar conceptual frameworks at various levels of abstraction, yielding a method for linking concepts together within and between levels of scale encountered in the grounded theory coding and categorization process. We conclude that this fractal analytic technique can bolster the aims of grounded theory as a formalized and systematic process for generating theory from empirical data. (shrink)

In this paper, I argue that no theory of consciousness can simultaneously respect four initially plausible metaphysical claims – namely, ‘first-person realism’, ‘non-solipsism’, ‘non-fragmentation’, and ‘one world’ – but that any three of the four claims are mutually consistent. So, theories of consciousness face a ‘quadrilemma’. Since it will be hard to achieve a consensus on which of the four claims to retain and which to give up, we arrive at a landscape of competing theories, all of which have (...) pros and cons. I will briefly indicate which kinds of theories correspond to the four horns of the quadrilemma. (shrink)

Recently, companions in guilt strategies have garnered significant philosophical attention as a response to arguments for moral error theory, the view that there are no moral facts and that our moral beliefs are thus systematically mistaken. According to Cuneo (The normative web: an argument for moral realism, Oxford University Press, Oxford, 2007), Das (Philos Q 66:152–160, 2016; Australas J Philos 95(1):58–69, 2017), Rowland (J Ethics Soc Philos 7(1):1–24, 2012; Philos Q 66:161–171, 2016) and others, epistemic facts would be just (...) as metaphysically problematic (or ‘guilty’) as moral facts. But since epistemic error theory is implausible, arguments for moral error theory prove too much and should be rejected. My aim is to argue that the success of this strategy is limited. In particular, the companions in guilt response fails against error-theoretic arguments motivated by concerns about explanatory dispensability, as recently developed by Joyce (The evolution of morality, MIT press, Bradford, 2005) and Olson (Moral error theory: history, critique, defence, Oxford University Press, Oxford, 2014: Ch. 7). To succeed, the response would require a prima facie plausible argument to the effect that epistemic facts are metaphysically dubious because they, too, are explanatorily dispensable. But, as I show, any such argument proves self-effacing: its premise commits us to believing in epistemic facts, while its conclusion forces us to deny their existence. Consequently, companions in guilt strategies don’t offer a panacea against arguments for moral error theory. (shrink)

Praktykowanie teorii. Koncepty wczesnych prac Daniela Libeskinda jako wzorce realnej architektury Treści wczesnych prac Libeskinda, w tym zwłaszcza idee zawarte w cyklach rysunków pod nazwą Micromegas: The Architecture of End Space (1979) i Chamber Works: Architectural Meditations on the Themes from Heraclitus (1983) oraz trzy maszyny określone jako Three Lessons in Architecture (1985) w decydujący sposób wpłynęły na wszystkie późniejsze realizacje architekta. Prace te w dużym zakresie zmieniły zasady oddzielania teorii od praktyki budowlanej, w tym tak- że odgraniczania architektury od (...) literatury czy filozofii. Już Micromegas były polemiką z traktowaniem rysunku architektonicznego wyłącznie jako utylitarnego narzędzia w procesie stwarzania budowli i postawiły na uczynienie z tej techniki pełnoprawnej postaci realnej architektury. Chamber Works w jeszcze większym stopniu niż prace z serii Micromegas akcentowały samodzielność rysunku i jego odrębność od wszelkiej rzeczywistości czy zewnętrznych źródeł treści. Maszyny połączone w Three Lessons in Architecture streszczały dokonania dawnych epok historii sztuki budowania. Reading Machine opowiadała o rzemieślniczych początkach, Memory Machine o intelektualizmie okresu nowożytnego, Writing Machine zaś o współczesnym okresie mechanizacji pamięci i kreacji. Zadaniem maszyn była metafizyczna refleksja nad głównymi założeniami i mitami architektury, a zarazem przeniesienie tej refleksji na poziom doświadczenia zmysłowego. W berlińskim Jüdisches Museum wymyślone liternictwo architektoniczne połączyło się z narracją na temat zagłady żydowskich mieszkańców miasta. Libeskind wykreował nie tyle budowlę,ile literacką relację o zbrodni przełamującej historię ludzkość. (shrink)

Many people are worried about the harmful effects of climate change but nevertheless enjoy some activities that contribute to the emission of greenhouse gas (driving, flying, eating meat, etc.), the main cause of climate change. How should such people make choices between engaging in and refraining from enjoyable greenhouse-gas-emitting activities? In this chapter, we look at the answer provided by decision theory. Some scholars think that the right answer is given by interactive decision theory, or game theory; (...) and moreover think that since private climate decisions are instances of the prisoner’s dilemma, one rationally should engage in these activities provided that one enjoys them. Others think that the right answer is given by expected utility theory, the best-known version of individual decision theory under risk and uncertainty. In this chapter, we review these different answers, with a special focus on the latter answer and the debate it has generated. (shrink)

What are conspiracy theories? And what, if anything, is epistemically wrong with them? I offer an account on which conspiracy theories are a unique way of holding a belief in a conspiracy. Specifically, I take conspiracy theories to be self-insulating beliefs in conspiracies. On this view, conspiracy theorists have their conspiratorial beliefs in a way that is immune to revision by counter-evidence. I argue that conspiracy theories are always irrational. Although conspiracy theories involve an expectation to encounter some seemingly disconfirming (...) evidence (allegedly planted by the conspirators), resistance to all counter- evidence cannot be justified on these grounds.

Darwin famously held that his use of the term "chance" in evolutionary theory merely "serves to acknowledge plainly our ignorance of the causes of each particular variation". Is this a tenable view today? Or should we revise our thinking about chance in evolution in light of the more advanced, quantitative models of Neo-Darwinian theory, which make substantial use of statistical reasoning and the concept of probability? Is determinism still a viable metaphysical doctrine about biological reality after the quantum (...) revolution in physics, or dowe have to abandon it in favor of an objective indeterminism? In light of such reflections, what is the relevant interpretation of probability in evolutionary theory? Do biologists use the concept of probability because they are finite cognitive agents or because the evolutionary process is fundamentally probabilistic? In this paper, I will show that we do not yet fully understand the nature of chance in evolution. (shrink)

In much of the current academic and public discussion, conspiracy theories are portrayed as a negative phenomenon, linked to misinformation, mistrust in experts and institutions, and political propaganda. Rather surprisingly, however, philosophers working on this topic have been reluctant to incorporate a negatively evaluative aspect when either analyzing or engineering the concept conspiracy theory. In this paper, we present empirical data on the nature of the concept conspiracy theory from five studies designed to test the existence, prevalence and (...) exact form of an evaluative dimension to the ordinary concept conspiracy theory. These results reveal that, while there is a descriptive concept of conspiracy theory, the predominant use of conspiracy theory is deeply evaluative, encoding information about epistemic deficiency and often also derogatory and disparaging information. On the basis of these results, we present a new strategy for engineering conspiracy theory to promote theoretical investigations and institutional discussions of this phenomenon. We argue for engineering conspiracy theory to encode an epistemic evaluation, and to introduce a descriptive expression—such as ‘conspiratorial explanation’—to refer to the purely descriptive concept conspiracy theory.

Over the course of its history, feminist standpoint theory has encountered a number of problems which reveal divisions among its supporters over certain fundamental philosophical commitments. This chapter sketches a phenomenological account of perception that can begin to address these problems, drawn largely from Maurice Merleau-Ponty’s Phenomenology of Perception. Merleau-Ponty can help us resolve these issues by providing an account of perspectival perception wherein a multiplicity of different perceptual standpoints all nonetheless put us in touch with a single external (...) world, and in which some standpoints may be better than others when it comes to accessing certain features of this world. For Merleau-Ponty, the proliferation of standpoints need not lead us into an unacceptably relativistic framework, as long as we are able to conceive of each of these standpoints as giving whoever occupies it access to some particular aspect of a singular, real, shared world.

In this enquiry I attempt to establish Universal Desire Theory as the nominal designation of my active ethical framework, a system heavily influenced by the natural essentialists Philippa Foot and Jenny Teichman, wherein the comparative amalgamation of all subjectively experienced biological harm and benefit is the foundation of objective normativity. Highlights of this paper include the sections where I discuss the moral life of the cell, as well as the moral fallibility of hallucinating persons under this system which combines (...) biological observation with conscious awareness of action. I hope you enjoy. (shrink)

This paper attempts to explain what a protest is by using the resources of speech-act theory. First, we distinguish the object, redress, and means of a protest. This provided a way to think of atomic acts of protest as having dual communicative aspects, viz., a negative evaluation of the object and a connected prescription of redress. Second, we use Austin’s notion of a felicity condition to further characterize the dual communicative aspects of protest. This allows us to distinguish protest (...) from some other speech acts which also involve a negative evaluation of some object and a connected prescription of redress. Finally, we turn to Kukla and Lance’s idea of a normative functionalist analysis of speech acts to advance the view that protests are a complex speech act constituted by dual input normative statuses and dual output normative statuses.

Abstract: According to a rationalist theory of introspection, rational agents have a capacity to believe they are in conscious states when they are in them, much as they have the capacity, for example, to avoid obvious contradictions in their beliefs. For the agent to know or believe by introspection, on this view, is for them to exercise that capacity. According to an acquaintance theory of introspection, by contrast, whenever an agent is in a conscious state, the agent is (...) aware of or is acquainted with being in the state, where the background notion of acquaintance is understood to be distinct from sense perception, on the one hand, and belief or knowledge, or the other. For the agent to know or believe by introspection, on this view, is for them to take advantage of the epistemic position they occupy in virtue of being acquainted in this way. These theories are not in conflict; it is possible to hold both an acquaintance theory and a rationalist theory. This paper, however, sets out and recommends a different possibility, namely, that of holding a rationalist theory while rejecting any acquaintance theory. (shrink)

Generally speaking, the existence of experience is accepted, but more challenging has been to say what experience is and how it occurs. Moreover, philosophers and scholars have been talking about mind and mental activity in connection with experience as opposed to physical processes. Yet, the fact is that quantum physics has replaced classical Newtonian physics in natural sciences, but the scholars in humanities and social sciences still operate under the obsolete Newtonian model. There is already a little research in which (...) mind and conscious experience are explained in terms of quantum theory. This article argues that experience is impossible to be both a physical and non-physical phenomenon. When discussing causality and identity as transcendental, quantum theory may imply the quantum physical nature of conscious experience, where a person associates causality to conscious experience, and, thus, the result is that the double-aspect theory and the mind/brain identity theory would be refuted.

In seeking an answer to the question of what it means for a theory to be fundamental, it is enlightening to ask why the current best theories of physics are not generally believed to be fundamental. This reveals a set of conditions that a theory of physics must satisfy in order to be considered fundamental. Physics aspires to describe ever deeper levels of reality, which may be without end. Ultimately, at any stage we may not be able to (...) tell whether we've reached rock bottom, or even if there is a base level – nevertheless, I draft a checklist to help us identify when to stop digging, in the case where we may have reached a candidate for a final theory. Given that the list is – according to (current) mainstream belief in high-energy physics – complete, and each criterion well-motivated, I argue that a physical theory that satisfies all the criteria can be assumed to be fundamental in the absence of evidence to the contrary (i.e., I argue that the necessary conditions are jointly sufficient for a claim of fundamentality in physics).

Several developments for diverse scientific goals, mostly in physics and physiology, had to take place, which eventually gave us fMRI as one of the central research paradigms of contemporary cognitive neuroscience. This technique stands on solid foundations established by the physics of magnetic resonance and the physiology of hemodynamics and is complimented by computational and statistical techniques. I argue, and support using concrete examples, that these foundations give rise to a productive theory-ladenness in fMRI, which enables researchers to identify (...) and control for the types of methodological and inferential errors. Consequently, this makes it possible for researchers to represent and investigate cognitive phenomena in terms of hemodynamic data and for experimental knowledge to grow independently of large scale theories of cognition.

I seek to advance enquiry into the point of a public higher education institution by drawing on ideals salient in the sub-Saharan African philosophical tradition. There are relational, and specifically communal, values prominently held by African thinkers that I use to ground a promising rival to the dominant contemporary Western, and especially Anglo-American, accounts of what a university ultimately ought to strive to achieve, which focus mainly on autonomy, truth, and citizenship. My aims are not merely comparative, contrasting an Afro-communal (...) approach with other ones that have been more globally influential, but also substantive. Although the theory of a university’s point that I articulate and defend has an African pedigree, I work to show that it should be taken seriously by a global audience, for plausibly capturing a variety of intuitions and claims that are widely shared.

Until recently, discussion of virtues in the philosophy of mathematics has been fleeting and fragmentary at best. But in the last few years this has begun to change. As virtue theory has grown ever more influential, not just in ethics where virtues may seem most at home, but particularly in epistemology and the philosophy of science, some philosophers have sought to push virtues out into unexpected areas, including mathematics and its philosophy. But there are some mathematicians already there, ready (...) to meet them, who have explicitly invoked virtues in discussing what is necessary for a mathematician to succeed. In both ethics and epistemology, virtue theory tends to emphasize character virtues, the acquired excellences of people. But people are not the only sort of thing whose excellences may be identified as virtues. Theoretical virtues have attracted attention in the philosophy of science as components of an account of theory choice. Within the philosophy of mathematics, and mathematics itself, attention to virtues has emerged from a variety of disparate sources. Theoretical virtues have been put forward both to analyse the practice of proof and to justify axioms; intellectual virtues have found multiple applications in the epistemology of mathematics; and ethical virtues have been offered as a basis for understanding the social utility of mathematical practice. Indeed, some authors have advocated virtue epistemology as the correct epistemology for mathematics (and perhaps even as the basis for progress in the metaphysics of mathematics). This topical collection brings together several of the researchers who have begun to study mathematical practices from a virtue perspective with the intention of consolidating and encouraging this trend.

Both mindreading and stereotyping are forms of social cognition that play a pervasive role in our everyday lives, yet too little attention has been paid to the question of how these two processes are related. This paper offers a theory of the influence of stereotyping on mental-state attribution that draws on hierarchical predictive coding accounts of action prediction. It is argued that the key to understanding the relation between stereotyping and mindreading lies in the fact that stereotypes centrally involve (...) character-trait attributions, which play a systematic role in the action–prediction hierarchy. On this view, when we apply a stereotype to an individual, we rapidly attribute to her a cluster of generic character traits on the basis of her perceived social group membership. These traits are then used to make inferences about that individual’s likely beliefs and desires, which in turn inform inferences about her behavior. (shrink)

The aims of this paper are to: (1) identify the best framework for comprehending multidimensional impact of deep brain stimulation on the self; (2) identify weaknesses of this framework; (3) propose refinements to it; (4) in pursuing (3), show why and how this framework should be extended with additional moral aspects and demonstrate their interrelations; (5) define how moral aspects relate to the framework; (6) show the potential consequences of including moral aspects on evaluating DBS’s impact on patients’ selves. Regarding (...) (1), I argue that the pattern theory of self can be regarded as such a framework. In realizing (2) and (3), I indicate that most relevant issues concerning PTS that require resolutions are ontological issues, including the persistence question, the “specificity problem”, and finding lacking relevant aspects of the self. In realizing (4), I identify aspects of the self not included in PTS which are desperately needed to investigate the full range of potentially relevant DBS-induced changes—authenticity, autonomy, and responsibility, and conclude that how we define authenticity will have implications for our concept of autonomy, which in turn will determine how we think about responsibility. Concerning (5), I discuss a complex relation between moral aspects and PTS—on one hand, they serve as the lens through which a particular self-pattern can be evaluated; on the other, they are, themselves, products of dynamical interactions of various self-aspects. Finally, I discuss (6), demonstrating novel way of understanding the effects of DBS on patients’ selves. (shrink)

Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic ‘oughts’ that apply in the first instance to belief-forming strategies that are partly under our control. I argue that the policy of systematically doubting or disbelieving conspiracy theories would be both a political disaster and the epistemic equivalent of self-mutilation, since (...) it leads to the conclusion that history is bunk and the nightly news unbelievable. In fact (of course) the policy is not employed systematically but is only wheeled on to do down theories that the speaker happens to dislike. I develop a deductive argument from hard-to-deny premises that if you are not a ‘conspiracy theorist’ in my anodyne sense of the word then you are an ‘idiot’ in the Greek sense of the word, that is, someone so politically purblind as to have no opinions about either history or public affairs. The conventional wisdom can only be saved (if at all) if ‘conspiracy theory’ is given a slanted definition. I discuss some slanted definitions apparently presupposed by proponents of the conventional wisdom (including, amongst others, Tony Blair) and conclude that even with these definitions the conventional wisdom comes out as deeply unwise. I finish up with a little harmless fun at the expense of David Aaronvitch whose abilities as a rhetorician and a popular historian are not perhaps matched by a corresponding capacity for logical thought.

Decision theory has at its core a set of mathematical theorems that connect rational preferences to functions with certain structural properties. The components of these theorems, as well as their bearing on questions surrounding rationality, can be interpreted in a variety of ways. Philosophy’s current interest in decision theory represents a convergence of two very different lines of thought, one concerned with the question of how one ought to act, and the other concerned with the question of what (...) action consists in and what it reveals about the actor’s mental states. As a result, the theory has come to have two different uses in philosophy, which we might call the normative use and the interpretive use. It also has a related use that is largely within the domain of psychology, the descriptive use. This essay examines the historical development of decision theory and its uses; the relationship between the norm of decision theory and the notion of rationality; and the interdependence of the uses of decision theory.

In this paper, I offer an analysis of the radical disagreement over the adequacy of string theory. The prominence of string theory despite its notorious lack of empirical support is sometimes explained as a troubling case of science gone awry, driven largely by sociological mechanisms such as groupthink (e.g. Smolin 2006). Others, such as Dawid (2013), explain the controversy by positing a methodological revolution of sorts, according to which string theorists have quietly turned to nonempirical methods of (...) class='Hi'>theory assessment given the technological inability to directly test the theory. The appropriate response, according to Dawid, is to acknowledge this development and widen the canons of acceptable scientific methods. As I’ll argue, however, the current situation in fundamental physics does not require either of these responses. Rather, as I’ll suggest, much of the controversy stems from a failure to properly distinguish the “context of justification” from the “context of pursuit”. Both those who accuse string theorists of betraying the scientific method and those who advocate an enlarged conception of scientific methodology objectionably conflate epistemic justification with judgements of pursuit-worthiness. Once we get clear about this distinction and about the different norms governing the two contexts, the current situation in fundamental physics becomes much less puzzling. After defending this diagnosis of the controversy, I’ll show how the argument patterns that have been posited by Dawid as constituting an emergent methodological revolution in science are better off if reworked as arguments belonging to the context of pursuit.

This paper articulates and responds to a challenge to contemporary compatibilist views of free will. Despite the popularity and appeal of compatibilist theories, many are left with lingering doubts about compatibilism. This paper explains this doubt in terms of the absurdity challenge: because a compatibilist accepts that they do not have causal access to all the actual sufficient causal sources of their own agency, the compatibilist can find their own agency absurd. By taking a cue from political philosophy, this paper (...) argues that a non-ideal construction of the problem of free will allows compatibilists to overcome this existential-metaphysical challenge, and by doing so, perhaps adopt a metaphysically progressive picture of human agency.

In this paper, I discuss the similarity between Wittgenstein’s use of thought experiments and Relativity Theory. I begin with introducing Wittgenstein’s idea of “thought experiments” and a tentative classification of different kinds of thought experiments in Wittgenstein’s work. Then, after presenting a short recap of some remarks on the analogy between Wittgenstein’s point of view and Einstein’s, I suggest three analogies between the status of Wittgenstein’s mental experiments and Relativity theory: the topics of time dilation, the search for (...) invariants, and the role of measuring tools in Special Relativity. This last point will help to better define Wittgenstein’s idea of description as the core of his philosophical enterprise. (shrink)

Is it possible to get by with just one ontological category? We evaluate L.A. Paul's attempt to do so: the mereological bundle theory. The upshot is that Paul's attempt to construct a one category ontology may be challenged with some of her own arguments. In the positive part of the paper we outline a two category ontology with property universals and kind universals. We will also examine Paul's arguments against a version of universal bundle theory that takes spatiotemporal (...) co-location instead of compresence or coinstantiation as the feature by which we can identify genuine bundles. We compare this novel theory, bundle theory with kinds, and Paul's mereological bundle theory and apply them to a case study concerning entangled fermions and co-located bosons. (shrink)

The new theory of reference has won popularity. However, a number of noted philosophers have also attempted to reply to the critical arguments of Kripke and others, and aimed to vindicate the description theory of reference. Such responses are often based on ingenious novel kinds of descriptions, such as rigidified descriptions, causal descriptions, and metalinguistic descriptions. This prolonged debate raises the doubt whether different parties really have any shared understanding of what the central question of the philosophical (...) class='Hi'>theory of reference is: what is the main question to which descriptivism and the causal-historical theory have presented competing answers. One aim of the paper is to clarify this issue. The most influential objections to the new theory of reference are critically reviewed. Special attention is also paid to certain important later advances in the new theory of reference, due to Devitt and others. (shrink)

The topic of a priori knowledge is approached through the theory of evidence. A shortcoming in traditional formulations of moderate rationalism and moderate empiricism is that they fail to explain why rational intuition and phenomenal experience count as basic sources of evidence. This explanatory gap is filled by modal reliabilism -- the theory that there is a qualified modal tie between basic sources of evidence and the truth. This tie to the truth is then explained by the (...) class='Hi'>theory of concept possession: this tie is a consequence of what, by definition, it is to possess (i.e., to understand) one’s concepts. A corollary of the overall account is that the a priori disciplines (logic, mathematics, philosophy) can be largely autonomous from the empirical sciences. (shrink)

A de minimis risk is defined as a risk that is so small that it may be legitimately ignored when making a decision. While ignoring small risks is common in our day-to-day decision making, attempts to introduce the notion of a de minimis risk into the framework of decision theory have run up against a series of well-known difficulties. In this paper, I will develop an enriched decision theoretic framework that is capable of overcoming two major obstacles to the (...) modelling of de minimis risk. The key move is to introduce, into decision theory, a non-probabilistic conception of risk known as normic risk. (shrink)

This article serves as either an addendum or as an expansion of ideas and work developed in my 2024 book, The Rationality Project: Across the Millennia, issued by Palgrave Macmillan. The book explores 21 potential theories for explaining rationality in terms of why and how one among these can serve in the position of explanatory power. The book does not fully explain all of these candidate theories, assigning that complete role to this addendum or work-in-progress. The main reason for this (...) abbreviation in assessing all the theories in the book is that the complete coverage—which this addendum allows—of all 21 theories would become too detailed for some philosophical readers. This addendum; one may consider, is then for the more technically minded reader—although certainly not-too-technically minded readers are welcome to explore it. If it becomes too bogged in detail for those latter kinds of readers, they may end up skimming the material in this addendum, trying at least to get the general idea of how these addendum sections fit into the book's goals.

Things and Their Place in Theories Our talk of external things, our very notion of things, is just a conceptual apparatus that helps us to foresee and ...

This paper develops a new kind of approach to conspiracy theories – a procedural approach. This approach promises to establish that belief in conspiracy theories is rationally criticisable in general. Unlike most philosophical approaches, a procedural approach does not purport to condemn conspiracy theorists directly on the basis of features of their theories. Instead, it focuses on the patterns of thought involved in forming and sustaining belief in such theories. Yet, unlike psychological approaches, a procedural approach provides a rational critique (...) of conspiracist thought patterns. In particular, it criticises these thought patterns for failing to conform to procedures prescribed by reason. The specific procedural approach that I develop takes its cue from the Kantian notion that reason must be used self-critically. I tentatively suggest that conspiracy theorists fail to engage in the relevant sort of self-critique in at least three ways: they do not critically examine their own motivations, they avoid looking at matters from the point of view of others, and they fail to reflect on the limits of human knowledge.

Conspiracy theories are often portrayed as unwarranted beliefs, typically supported by suspicious kinds of evidence. Yet contemporary work in Philosophy argues provisional belief in conspiracy theories is at the very least understandable---because conspiracies occur---and that if we take an evidential approach, judging individual conspiracy theories on their particular merits, belief in such theories turns out to be warranted in a range of cases. -/- Drawing on this work, I examine the kinds of evidence typically associated with conspiracy theories, and show (...) how the so-called evidential problems with conspiracy theories are also problems for the kinds of evidence put forward in support of other theories. As such, if there is a problem with the conspiracy theorist's use of evidence, it is one of principle: is the principle which guides the conspiracy theorist's use of evidence somehow in error? I argue that whatever we might think about conspiracy theories generally, there is no prima facie case for a scepticism of conspiracy theories based purely on their use of evidence. (shrink)

A response to Lee Basham's 'The Need for Accountable Witnesses: A Reply to Dentith'.

A platitude that took hold with Kuhn is that there can be several equally good ways of balancing theoretical virtues for theory choice. Okasha recently modelled theory choice using technical apparatus from the domain of social choice: famously, Arrow showed that no method of social choice can jointly satisfy four desiderata, and each of the desiderata in social choice has an analogue in theory choice. Okasha suggested that one can avoid the Arrow analogue for theory choice (...) by employing a strategy used by Sen in social choice, namely, to enhance the information made available to the choice algorithms. I argue here that, despite Okasha’s claims to the contrary, the information-enhancing strategy is not compelling in the domain of theory choice. (shrink)

Ranking theory is one of the salient formal representations of doxastic states. It differs from others in being able to represent belief in a proposition (= taking it to be true), to also represent degrees of belief (i.e. beliefs as more or less firm), and thus to generally account for the dynamics of these beliefs. It does so on the basis of fundamental and compelling rationality postulates and is hence one way of explicating the rational structure of doxastic states. (...) Thereby it provides foundations for accounts of defeasible or nonmonotonic reasoning. It has widespread applications in philosophy, it proves to be most useful in Artificial Intelligence, and it has started to find applications as a model of reasoning in psychology. (shrink)

In 2005, Charles Mills published “‘Ideal Theory’ as Ideology” in Hypatia: a withering critique of much of contemporary political philosophy and ethics. For Mills such work in philosophy failed to attend to the realities of social life and politics, and in remaining silent on actual issues of domination and oppression served an ideological role in supporting the interests of white bourgeois men. Around the time that Charles Mills launched his broadside against ideal theory, trans theorists had been fighting (...) their own battle against the abstraction of theory from the realities of trans lives and oppression. Vivian Namaste (2000) and Jay Prosser (1998) argued that contemporary gender theory failed to justice to the actuality of trans life, retreating instead to understanding trans life through literary archetypes and idealized radical figures. In this chapter I’ll compare Mills’ critique of ideal theory with the transfeminist critique of 1990s gender theory, arguing that they share much in common. Centrally, both critiques share an underlying commitment to theory needing to be grounded in the actuality of oppression and power relations. This common thread, I suggest, must continue to guide transfeminist thought and action: contra Marquis Bey (2022) transfeminist thought and praxis must continue to be about trans lives, about the oppression of trans women, and about ways of actually achieving liberation from our current dire position.
