I provide a characterization of weakly pseudo-rationalizable choice functions---that is, choice functions rationalizable by a set of acyclic relations---in terms of hyper-relations satisfying certain properties. For those hyper-relations Nehring calls extended preference relations, the central characterizing condition is weaker than (hyper-relation) transitivity but stronger than (hyper-relation) acyclicity. Furthermore, the relevant type of hyper-relation can be represented as the intersection of a certain class of its extensions. These results generalize known, analogous results for path independent choice functions.

Saunders' recent arguments in favour of the weak discernibility of (certain) quantum particles seem to be grounded in the 'generalist' view that science only provides general descriptions of the worlIn this paper, I introduce the ‘generalist’ perspective and consider its possible justification and philosophical basis; and then look at the notion of weak discernibility. I expand on the criticisms formulated by Hawley (2006) and Dieks and Veerstegh (2008) and explain what I take to be the basic problem: that the properties (...) invoked by Saunders cannot be pointed to as ‘individuators’ of otherwise indiscernible (and thus numerically identical) entities because their ontological status remains underdetermined by the evidence and the established interpretation of the theory. In addition to to this, I suggest that Saunders does not deal adequately with bosons, and cannot do so exactly because he subscribes to PII and the generalist picture. The last part of the paper contains a critical examination of the claim (or at least implicit assumption) that the generalist picture should be regarded as obviously compelling by the modern-day empiricist.

Recently, many philosophers have been interested in using locative relations to clarify and pursue debates in the metaphysics of material objects. Most begin with the relation of exact location. But what if we begin instead with the relation known as weak location – the relation an object x bears to any region not completely bereft of x? I explore some of the consequences of pursuing this route for issues including coincidence, extended simples, and endurance, with an eye to evaluating the (...) prospects for taking weak location as our fundamental locative relation.

This paper generalizes rationalizability of a choice function by a single acyclic binary relation to rationalizability by a set of such relations. Rather than selecting those options in a menu that are maximal with respect to a single binary relation, a weakly pseudo-rationalizable choice function selects those options that are maximal with respect to at least one binary relation in a given set. I characterize the class of weakly pseudo-rationalizable choice functions in terms of simple functional properties. This result also (...) generalizes Aizerman and Malishevski's characterization of pseudo-rationalizable choice functions, that is, choice functions rationalizable by a set of total orders. (shrink)

Mental conflict not always amounts to weakness of will. Irresistible motives not always speak of addiction. This book proposes an integrated account of what singles out these phenomena: addiction and weakness of will are both forms of secondary akrasia. By integrating these two phenomena into a classical conception of akrasia as poor resolution of an unnecessary conflict – valuing without intending while intending without valuing – the book makes an original contribution to central issues in moral psychology and (...) philosophy of action, including the relationship between responsibility and intentional agency, and the nature and scope of moral appraisal. In particular, the proposed integrated account is grounded in a general theory of responsibility and a related model of action as actualisation bringing together insights from both volitional and non-volitional conceptions, such as the intuition that it is unfair to hold a person responsible for things that are not up to her and the parity of actions and attitudes as legitimate objects of moral appraisal. Furthermore, the actualisation model supports a distinctive version of the Guise of the Good thesis which links valuing and intending in terms of success in action and explains why akratic actions and their offspring – addiction and weakness of will – are necessarily less than successful yet fully responsible.

There are well-known quasi-formal arguments that identity is a "strict" relation in at least the following three senses: (1) There is a single identity relation and a single distinctness relation; (2) There are no contingent cases of identity or distinctness; and (3) There are no vague or indeterminate cases of identity or distinctness. However, the situation is less clear cut than it at first may appear. There is a natural formal theory of identity that is very close to the standard (...) classical theory but which does not validate the formal analogues of (1)-(3). The core idea is simple: We weaken the Principle of the Indiscernibility of Identicals from a conditional to an entailment and we adopt a weakly classical logic. This paper investigates this weakly classical theory of identity (and related theories) and discusses its philosophical ramifications. It argues that we can accept a reasonable theory of identity without committing ourselves to the uniqueness, necessity, or determinacy of identity. (shrink)

In this paper we present an account of practical rationality and weakness of will in terms of rational capacities. We show how our account rectifies various shortcomings in Michael Smith's related theory. In particular, our account is capable of accommodating cases of weak-willed behaviour that are not `akratic', or otherwise contrary to the agent's better judgement. Our account differs from Smith's primarily by incorporating resolve: a third rational capacity for resolute maintenance of one's intentions. We discuss further two ways (...) to explain the importance of resolve to practical rationality: one based on Richard Holton's recent work, and an alternative, non-consequentialist account. (shrink)

How does our language relate to reality? This is a question that is especially pertinent in set theory, where we seem to talk of large infinite entities. Based on an analogy with the use of models in the natural sciences, we argue for a threefold correspondence between our language, models, and reality. We argue that so conceived, the existence of models can be underwritten by a weak notion of existence, where weak existence is to be understood as existing in virtue (...) of language. (shrink)

A consequence relation is strongly classical if it has all the theorems and entailments of classical logic as well as the usual meta-rules (such as Conditional Proof). A consequence relation is weakly classical if it has all the theorems and entailments of classical logic but lacks the usual meta-rules. The most familiar example of a weakly classical consequence relation comes from a simple supervaluational approach to modelling vague language. This approach is formally equivalent to an account of logical consequence according (...) to which α1, ..., αn entails β just in case □α1, ..., □αn entails □β in the modal logic S5. This raises a natural question: If we start with a different underlying modal logic, can we generate a strongly classical logic? This paper explores this question. In particular, it discusses four related technical issues: (1) Which base modal logics generate strongly classical logics and which generate weakly classical logics? (2) Which base logics generate themselves? (3) How can we directly characterize the logic generated from a given base logic? (4) Given a logic that can be generated, which base logics generate it? The answers to these questions have philosophical interest. They can help us to determine whether there is a plausible supervaluational approach to modelling vague language that yields the usual meta-rules. They can also help us to determine the feasibility of other philosophical projects that rely on an analogous formalism, such as the project of defining logical consequence in terms of the preservation of an epistemic status.

This paper is my best attempt to confute (Kantian) Modern Philosophy at its very core. This implies, of course, that in my view the principles of Critical Realism are Kantian. The basic arguments supporting Critical Realism are powerful: I have tried to show clearly their power, but also to expose clearly their putrid root. Section 3 on the principle of immanence offers the most important contribution in this undertaking. The arguments of critical realism studied in this paper are the following: (...) 1. The Notion of Experience 2. The Nature of Knowledge: Question and Inquiry 3. The Principle of Immanence 4. The Notion of Relation 5. Judgment as the Position of the Real. (shrink)

This paper presents a semantical analysis of the Weak Kleene Logics Kw3 and PWK from the tradition of Bochvar and Halldén. These are three-valued logics in which a formula takes the third value if at least one of its components does. The paper establishes two main results: a characterisation result for the relation of logical con- sequence in PWK – that is, we individuate necessary and sufficient conditions for a set.

In this paper we consider Mark Bedau’s notion of weak emer- gence (WE) and relate it to various attempts to objectively construe complexity. We argue that the heavy reliance on a specific notion of complexity risks rendering the concept superfluous. Furthermore we discuss what sort of systems might reasonably be understood as exhibiting emergence at all and point out that the macro-level needs to be at least min- imally structured. A worry may thus be formed that macro- level generalisations provide (...) the sort of short-cut that is ex- plicitly excluded from WE thus potentially making the con- cept apply only to chaotic systems of limited interest (in this context).

Notions of agency and of weakness of will clearly seem to be related to one another. This essay takes on a rather modest task in relation to current discussion of these topics; it seeks to establish the following claim: If A is a normal human agent, weakness of will is possible for A. The argument relies on demonstrating that certain necessary conditions for normal human agency are at least roughly equivalent to certain sufficient conditions for weakness of (...) will. The connection between agency and weakness of will is made through the use of an extended example that lays bare the links between the two. (shrink)

Our aim is to provide a sequent calculus whose external consequence relation coincides with the three-valued paracomplete logic `of nonsense' introduced by Dmitry Bochvar and, independently, presented as the weak Kleene logic K3W by Stephen C. Kleene. The main features of this calculus are (i) that it is non-reflexive, i.e., Identity is not included as an explicit rule (although a restricted form of it with premises is derivable); (ii) that it includes rules where no variable-inclusion conditions are attached; and (iii) (...) that it is hybrid, insofar as it includes both left and right operational introduction as well as elimination rules.

The problem of measurement in economic models and the possibility of their quantum-mechanical description are considered. It is revealed that the apparent paradox of such a description is associated with a priori requirement of conformity of the model to all the alternatives of free choice of the observer. The measurement of the state of a trader on a stock exchange is formally defined as his responses to the proposals of sale at a fixed price. It is shown that an analogue (...) of Bell's inequalities for this measurement model is violated at the most general assumptions related to the strategy of the trader and requires a quantummechanical description of the dynamics of his condition. In the framework of the theory of weak continuous quantum measurements, the equation of stock price dynamics and the quantum-mechanical generalization of the F. Black and M. Scholes model for pricing options are obtained. The fundamental distinctions between the obtained model and the classical one are discussed. (shrink)

This paper extends Fitting's epistemic interpretation of some Kleene logics, to also account for Paraconsistent Weak Kleene logic. To achieve this goal, a dualization of Fitting's "cut-down" operator is discussed, rendering a "track-down" operator later used to represent the idea that no consistent opinion can arise from a set including an inconsistent opinion. It is shown that, if some reasonable assumptions are made, the truth-functions of Paraconsistent Weak Kleene coincide with certain operations defined in this track-down fashion. Finally, further reflections (...) on conjunction and disjunction in the weak Kleene logics accompany this paper, particularly concerning their relation with containment logics. These considerations motivate a special approach to defining sound and complete Gentzen-style sequent calculi for some of their four-valued generalizations. (shrink)

In Animal Ethics in Context, Clare Palmer tries to harmonise two competing approaches to animal ethics. One focuses on the morally relevant capacities that animals possess. The other is the Laissez-Faire Intuition (LFI): the claim that we have duties to assist domesticated animals but should (at least generally) leave wild animals alone. In this paper, I critique the arguments that Palmer offers in favour of the No-Contact LFI - the view that we have (prima facie) duties not to harm wild (...) animals but no duties to assist them. I argue that Palmer's endorsement of the No-Contact LFI is unwarranted. Her arguments actually provide strong reasons to endorse what I call the Gradient View - a position that posits weak presumptive duties to assist wild animals that become stronger as our relations with the animals grow stronger.

This paper deals with a collection of concerns that, over a period of time, led the author away from the Routley–Meyer semantics, and towards proof- theoretic approaches to relevant logics, and indeed to the weak relevant logic MC of meaning containment.

This paper presents an account of akrasia, drawn from the work of William James, that sees akrasia as neither a rational failing (as with most philosophical accounts) nor a moral failing (as with early Christian accounts), but rather a necessary by-product of our status as biological beings. By examining James’s related accounts of motivation and action, I argue that akratic actions occur when an agent attempts to act against her settled habits, but fails to do so. This makes akrasia a (...) product of the agent’s practical failure to adequately structured her environment to bring about her desired action. Akratic action performs the vital function of revealing to the agent the exact point at which her cognitive effort was insufficient for bringing about her intended action. It also reveals that future improvement is within her control. As such, akratic action is the very foundation of James’s meliorism. (shrink)

Speaking skill is one of the most important skills of the four language skills. It is believed as an indicator of competency in a language. Nazara (2011) considers speaking skill as an essential skill of the four language skills and suggests that EFL students have to master the speaking skill. Unfortunately, the majority of Afghan EFL undergraduates are facing issues in the speaking skill. Most of Afghan undergraduate EFL learners are good in reading and writing but they are not accurate (...) and fluent in oral communication (Zia and Sulan, 2015). Hence, this study was conducted to particularly investigate student-related factors that affect students’ speaking skill. A mixed-method approach was used for the study. Data was collected through questionnaires and interviews. The data collected through questionnaires was analyzed in SPSS whereas the data collected through interviews was thematically analysed. A total of 90 students were purposively selected and participated in the study. The findings show that psychological factors and weak background of English language in the part of students were some of the factors that impede students speaking skill. It is hoped that the findings of the current study will help teachers as well as educators to be attentive toward students-related responsibilities to reduce the factors that affect students' speaking skill.

Minimal Negation is defined within the basic positive relevance logic in the relational ternary semantics: B+. Thus, by defining a number of subminimal negations in the B+ context, principles of weak negation are shown to be isolable. Complete ternary semantics are offered for minimal negation in B+. Certain forms of reductio are conjectured to be undefinable (in ternary frames) without extending the positive logic. Complete semantics for such kinds of reductio in a properly extended positive logic are offered.

This thesis consists of three papers examining determinants and implications of related party transactions (RPTs) in Vietnam, a transitional economy in South East Asia with features of concentrated state ownership and weak minority investor protection. Specifically, these papers describe RPTs and examine (i) the association between RPTs and state ownership, (ii) the association between the cost of corporate debt and RPTs, and the moderating role of state ownership on the association between the cost of debt and RPTs, and (iii) the (...) association between corporate tax avoidance and RPTs, and the moderating role of state ownership on this potential association. The first paper describes the nature and extent of RPTs in Vietnamese listed firms and examines the association between RPTs and state ownership. The results from this paper demonstrate that related party transactions are prevalent in Vietnam. Findings show that the presence of state ownership is related to a lower extent of RPTs. However, among firms with state ownership, the extent of RPTs is positively associated with percentage of state ownership. The second paper reveals that the cost of debt is higher in firms having a higher level of RPTs, implying that RPTs are viewed as a potential risk to firms from the point of view of lenders. However, the presence of state ownership can reduce the effect of RPTs on the cost of debt. The third paper provides evidence that firms with RPTs demonstrate more tax avoidance than their counterparts without RPTs. Further, among firms with RPTs, firms with a higher extent of related net credit and related sales are found to exhibit even higher levels of tax avoidance. However, the association between tax avoidance and RPTs is moderated by the presence of state ownership. Finally, in firms with RPTs, the presence of state ownership reduces tax avoidance measured by effective tax rates. (shrink)

The dominant view amongst contemporary Western philosophers about the essence of a natu­ ral object is that it is constituted by its intrinsic properties. The ontological approach salient in the African philosophical tradition, in contrast, accounts for a thing’s essence by appeal to its relational properties. The Afro­relational ontology is under­developed, with the primary aim of this article being to help rectify that weakness. Specifically, this article’s aims are: to articulate an African approach to understanding the essence (...) of a concrete, natural thing in terms of its relationships; to illustrate the Afro­relational approach with the examples of the self and of water; to contrast the Afro­relational characterization of the essence of the self and of water with a typically Western construal in terms of their intrinsic properties; and finally to provide an initial defence of the Afro­relational approach, both by responding to some objections facing it and by providing some new, positive reasons to take it seriously.

In this paper, we propose a methodology to maximize the benefits of interdisciplinary cooperation in AI research groups. Firstly, we build the case for the importance of interdisciplinarity in research groups as the best means to tackle the social implications brought about by AI systems, against the backdrop of the EU Commission proposal for an Artificial Intelligence Act. As we are an interdisciplinary group, we address the multi-faceted implications of the mass-scale diffusion of AI-driven technologies. The result of our exercise (...) lead us to postulate the necessity of a behavioural theory that standardizes the interaction process of interdisciplinary groups. In light of this, we conduct a review of the existing approaches to interdisciplinary research on AI appliances, leading to the development of methodologies like ethics-by-design and value-sensitive design, evaluating their strengths and weaknesses. We then put forth an iterative process theory hinging on a narrative approach consisting of four phases: definition of the hypothesis space, building-up of a common lexicon, scenario-building, interdisciplinary self-assessment. Finally, we identify the most relevant fields of application for such a methodology and discuss possible case studies. (shrink)

Everyone thinks they know who Prince Zuko is and can be. His father, Fire Lord Ozai, and sister, Azula, think him weak, disobedient, and undeserving of the crown. His Uncle Iroh thinks him good, if troubled, but ultimately worthy of his faith. The kids initially think him a villain, but eventually come to see him as a person – neither monster nor saint – someone who can choose to go in a new way. Zuko himself shows great ambivalence between these (...) conflicting stories about who he is, though each one helps to craft his own self-understanding. In this paper, we apply Hilde Lindemann’s narrative account of the self to explore the ways that others “hold” Zuko in one identity or “let him go” from others. According to Lindemann, our personal identities consist of the first- and third-person stories that cluster around significant acts, relationships, and commitments in our lives. Our identities are fundamentally relational, formed by the interaction between our own self-conception and the ways in which others see us. As such, others’ stories can enable or prevent us from imaginatively projecting ourselves into a particular future. This can lead us to becoming trapped in our identities; without the possibility of being perceived differently by others, we might find ourselves unable to try different ways of being or acting. The converse is also true, in that others can open up new possible identities by seeing things in us that we have trouble seeing in ourselves. If others in our moral community see us as wicked, beyond redemption and unable to repair our wrongs, we are held in the role of the villain and might come to live into that role without question. Zuko’s story is a perfect illustration of Jean Harvey’s reminder that, “it is just not true that once a thief, always a thief” and that agents can choose to go in a new way, can choose to change. How does Zuko change? We argue that Zuko’s redemption is enabled by those in his moral community holding him in identities in which he is a good person, capable and deserving of care, friendship, and love. While the identity he has in relation to his father and sister closes down many possible futures, his uncle Iroh in particular persists in holding him in an identity in which he is loved and worthy of love. And in doing so - in holding this space for him - Iroh opens up a way for Zuko to exercise agency and choose to become a different kind of person than the one he thought he was destined to be.

The philosophies of education serve as the guide of the teachers in handling the teaching-learning process. However, a belief will remain as a belief unless it is practiced. This study aimed to find the relationship between the philosophical beliefs and practices of the 30 teachers of the schools in San Roque, Mabini, Bohol - San Roque Elementary School and San Roque National High School, S.Y. 2019-2020. The study utilized a quantitative method descriptive survey research design. The research instrument used was (...) a self-constructed questionnaire in which the reliability was tested by a Cronbach’s Alpha using Statistical Package for the Social Science (SPSS) software. Simple percentage and weighted mean were some of the statistical treatments used. Kendall’s tau_b, a non-parametric test, was used to determine the correlation between philosophical beliefs and their equivalent pedagogical practices. All of the statistical treatments were also run using the SPSS software. Further, the researcher assured the proper observation of the research ethics protocol. Based on the results, the philosophies of Progressivism (3.63) and Perennialism (3.31) were the most and least prevailing philosophical beliefs, respectively. On the other hand, the most and least prevailing philosophies practiced are Progressivism (3.69) and Essentialism (3.19), respectively. Moreover, research findings revealed that there was a significant relationship between the philosophical beliefs of teachers and their pedagogical practices. In conclusion, this study claims that teachers’ pedagogical practices are dependent to their philosophical beliefs; and as the teachers believed on a particular philosophy of education, they practice it accordingly to the extent of their adherence to the belief.

This paper discusses possible forms of loss or weakness of the ability to interact with others and the ways in which this arises. In particular, in the context of socio-affective knowledge and related failures, it focuses on certain deficits that primarily involve the body. The article aims to show that the “destiny” of our inner drives and our lives—the specific solutions to which they are forced in their vicissitudes—is less “blind” than it appears, leaving (albeit minimal) margins of escape, (...) also because it has a relational connotation. Starting from Bernhard Waldenfels’s recent work on the relationship between phenomenology and psychoanalysis, in which this question is addressed from a phenomenological-responsive point of view, this article reflects on the problem by establishing a comparison between Waldenfels’s philosophy and Max Scheler’s phenomenology of values. Beyond the differences that their approaches to the problem of relational deficits present, Waldenfels and Scheler can be put in fruitful dialogue with each other, starting from their common interest in Freudian psychoanalysis. Within this framework, it is possible to evaluate, adopting Scheler’s point of view, both a methodological aspect and a psychological presupposition of Freud’s ontogenesis of sympathy and love: associationism. From this perspective, Freud reveals himself in part as an heir to British empiricism. I will argue that, with and beyond Freud, the human being is not reducible to a mere sum of blind sensations or blind drives and that for both at least certain forms of inability to interact with others are derivative—deformations of normal responsivity and aberrations of normal pulsional-(relational) life—rather than originary phenomena.

Logics based on weak Kleene algebra (WKA) and related structures have been recently proposed as a tool for reasoning about flaws in computer programs. The key element of this proposal is the presence, in WKA and related structures, of a non-classical truth-value that is “contaminating” in the sense that whenever the value is assigned to a formula ϕ, any complex formula in which ϕ appears is assigned that value as well. Under such interpretations, the contaminating states represent occurrences of a (...) flaw. However, since different programs and machines can interact with (or be nested into) one another, we need to account for different kind of errors, and this calls for an evaluation of systems with multiple contaminating values. In this paper, we make steps toward these evaluation systems by considering two logics, HYB1 and HYB2, whose semantic interpretations account for two contaminating values beside classical values 0 and 1. In particular, we provide two main formal contributions. First, we give a characterization of their relations of (multiple-conclusion) logical consequence—that is, necessary and sufficient conditions for a set Δ of formulas to logically follow from a set Γ of formulas in HYB1 or HYB2 . Second, we provide sound and complete sequent calculi for the two logics. (shrink)

The relations between rationality and optimization have been widely discussed in the wake of Herbert Simon's work, with the common conclusion that the rationality concept does not imply the optimization principle. The paper is partly concerned with adding evidence for this view, but its main, more challenging objective is to question the converse implication from optimization to rationality, which is accepted even by bounded rationality theorists. We discuss three topics in succession: (1) rationally defensible cyclical choices, (2) the revealed preference (...) theory of optimization, and (3) the infinite regress of optimization. We conclude that (1) and (2) provide evidence only for the weak thesis that rationality does not imply optimization. But (3) is seen to deliver a significant argument for the strong thesis that optimization does not imply rationality. (shrink)

Abstract -/- Kratzer’s semantics for the deontic modals ought, must, etc., is criticized and improvements are suggested. Specifically, a solution is offered for the strong/weak, must/ought contrast, based on connecting must to right and ought to good as their respective ordering norms. A formal treatment of the semantics of must is proposed. For the semantics of ought it is argued that good enough should replace best in the formula giving truth conditions. A semantics for supposed to slightly different from that (...) for ought is proposed that connects interestingly with the “normative judgement internalism” problem. An extended analysis of the workings of the ordering source in Kratzer semantics reveals several problems and related possible solutions. And finally, it is argued that ‘We must do the right things” and “We ought to pursue good things” are provably necessary in Kratzer semantics, which is, I think, a welcome result, although, since formal, does not tell what are the right and good things.

This paper intends to further the understanding of the formal properties of (higher-order) vagueness by connecting theories of (higher-order) vagueness with more recent work in topology. First, we provide a “translation” of Bobzien's account of columnar higher-order vagueness into the logic of topological spaces. Since columnar vagueness is an essential ingredient of her solution to the Sorites paradox, a central problem of any theory of vagueness comes into contact with the modern mathematical theory of topology. Second, Rumfitt’s recent topological reconstruction (...) of Sainsbury’s theory of prototypically defined concepts is shown to lead to the same class of spaces that characterize Bobzien’s account of columnar vagueness, namely, weakly scattered spaces. Rumfitt calls these spaces polar spaces. They turn out to be closely related to Gärdenfors’ conceptual spaces, which have come to play an ever more important role in cognitive science and related disciplines. Finally, Williamson’s “logic of clarity” is explicated in terms of a generalized topology (“locology”) that can be considered an alternative to standard topology. Arguably, locology has some conceptual advantages over topology with respect to the conceptualization of a boundary and a borderline. Moreover, in Williamson’s logic of clarity, vague concepts with respect to a notion of a locologically inspired notion of a “slim boundary” are (stably) columnar. Thus, Williamson’s logic of clarity also exhibits a certain affinity for columnar vagueness. In sum, a topological perspective is useful for a conceptual elucidation and unification of central aspects of a variety of contemporary accounts of vagueness. (shrink)

The first aim of this paper is to prove a topological completeness theorem for a weak version of Stalnaker’s logic KB of knowledge and belief. The weak version of KB is characterized by the assumption that the axioms and rules of KB have to be satisfied with the exception of the axiom (NI) of negative introspection. The proof of a topological completeness theorem for weak KB is based on the fact that nuclei (as defined in the framework of point-free topology) (...) give rise to a profusion of topological belief operators that are compatible with the familiar topological knowledge operator. Thereby a canonical topological model for weak KB can be constructed. For this canonical model a truth lemma for the K and B holds such that a completeness theorem for KB can be proved in the familiar way. The second aim of this paper is to show that the topological interpretation of knowledge K comes along with a complete Heyting algebra of belief operators B that all fit the knowledge operator K in the sense that the pairs (K, B) satisfy all axioms of weak KB. This amounts to a pluralistic relation between knowledge and belief: Knowledge does not fully determine belief, rather it designs a conceptual space for belief operators where different (competing) belief operators coexist.

To act akratically is to act, knowingly, against what you judge is best for you to do, and it is traditionally assumed that to do this is to be weak-willed. Some have rejected this identification of akrasia and weakness of will, arguing that the latter is instead best understood as a matter of abandoning one's reasonable resolutions. This paper also rejects the identification of akrasia and weakness of will, but argues that this alternative conception is too broad, and (...) that weakness of will is best understood in relation to certain kinds of pain and pleasure. Moreover, the phenomenon of strong-willed akrasia, cases in which a person must exhibit strength of will to do precisely what she judges she should not do, suggests that strength of will is an executive virtue, and that being weak-willed is just one way (among others) in which a person can fail to manifest this virtue.

In the following paragraphs, I will describe ten strategies through which we can show the weaknesses of every form of theism based on the "One God", while postulating that the Trinity is a good solution. This approach follows up on Swinburne’s claims about the existence of a priori and a posteriori proofs for the existence of the Trinity (his proofs are part of the sixth strategy). Clearly, these strategies are not “new”: they have been advocated by many thinkers in the (...) past and in the present. I merely revived them, and brought them together in a kind of cumulative reasoning: the strength of them arises when these strategies are considered together, showing that the Trinity is a reasonable hypothesis even though it is contradictory. The proposed strategies lead to the conclusion that there must exist in God something similar to what we call ‘real relations’ and ‘multiplicity’; and in order for God to be relational, there must exist in Him some “distincts” that relate to one another. This is postulated by philosophical reasoning, not just by Revelation, and regardless of the choice to support a process metaphysics. As Trinitarian theology contains the mystery of eternal generation, the strategies do account for the fact that in philosophy we contemplate the mystery of eternal self-distinction and of all the other ‘self-actions’ of the One. The eternal generation remains mysterious, but it is the idea that best helps us describe how God is (One and Triune) and how he creates the world. God must be Triune in every theistic system. The One God is, as One, also Triune. The Unity-Trinity of the Principle is the only apophatic point that we can reach from many quarters. Once autonomous paths of reason have established that God is a Person and Persons, One-Multiple, Creator (communicated), Free, Relational and Infinite possibility, it therefore emerges that our most reliable hypothesis is that of the Trinitarian God.

Large sets of elements interacting locally and producing specific architectures reliably form a category that transcends the usual dividing line between biological and engineered systems. We propose to call them morphogenetically architected complex systems (MACS). While taking the emergence of properties seriously, the notion of MACS enables at the same time the design (or “meta-design”) of operational means that allow controlling and even, paradoxically, programming this emergence. To demonstrate our claim, we first show that among all the self-organized systems studied (...) in the field of Artificial Life, the specificity of MACS essentially lies in the close relation between their emergent properties and functional properties. Second, we argue that to be a MACS a system does not need to display more than weak emergent properties. Third, since the notion of weak emergence is based on the possibility of simulation, whether computational or mechanistic via machines, we see MACS as good candidates to help design artificial self-architected systems (such as robotic swarms) but also harness and redesign living ones (such as synthetic bacterial films).

What marks emergence as a metaphysically interesting idea is that many macro-level entities and their properties are ontologically and causally autonomous in relation to the micro-level entities and properties they depend on---or so argues Jessica Wilson in Metaphysical Emergence (2021). To do so, she adopts a “metaphysically highly neutral” (p. 32) approach to questions about powers, causation, properties, and laws. That is, while explaining what emergence is and arguing that there is indeed emergence in the natural world, she doesn’t restrict (...) her analyses and arguments to any specific metaphysical accounts of these concepts, and she doesn’t commit to any controversial theses about them. In this article, I assess Wilson’s project against this methodological ideal of metaphysical neutrality. (shrink)

There are many things—call them ‘experts’—that you should defer to in forming your opinions. The trouble is, many experts are modest: they’re less than certain that they are worthy of deference. When this happens, the standard theories of deference break down: the most popular (“Reflection”-style) principles collapse to inconsistency, while their most popular (“New-Reflection”-style) variants allow you to defer to someone while regarding them as an anti-expert. We propose a middle way: deferring to someone involves preferring to make any decision (...) using their opinions instead of your own. In a slogan, deferring opinions is deferring decisions. Generalizing the proposal of Dorst (2020a), we first formulate a new principle that shows exactly how your opinions must relate to an expert’s for this to be so. We then build off the results of Levinstein (2019) and Campbell-Moore (2020) to show that this principle is also equivalent to the constraint that you must always expect the expert’s estimates to be more accurate than your own. Finally, we characterize the conditions an expert’s opinions must meet to be worthy of deference in this sense, showing how they sit naturally between the too-strong constraints of Reflection and the too-weak constraints of New Reflection.

There is more than one way to say that composition is identity. Yi has distinguished the Weak Composition thesis from the Strong Composition thesis and attributed the former to David Lewis while noting that Lewis associates something like the latter with me. Weak Composition is the thesis that the relation between the parts collectively and their whole is closely analogous to identity. Strong Composition is the thesis that the relation between the parts collectively and their whole is identity. Yi is (...) right that Strong Composition does not fully reflect my view. We must recognize further what, borrowing Lewis's characterization, could be called the "stronger, and stranger" Composition thesis, or what I'll call the Stronger Composition thesis for short. On Strong Composition, it is only collectively that the parts are identical with the whole. On Stronger Composition, they are individually identical with it as well. I will explain and motivate this thesis. (shrink)

Self-consciousness relates to important themes, such as sentience and personhood, and is often the cornerstone of moral theories (Warren, 1997). However, not much attention is given to future moral creatures of the earth: robots. This may be due to the unsettled status of their experience, which is why I have chosen to find the necessary features of self-consciousness in them. Philosophy of mind is also my interest which I have developed since I rejected the idea of souls and could not (...) account for my own phenomenal experiences. Among the current answers to the hard problem of consciousness (Chalmers, 1995) one stood out to me – Daniel Dennett’s multiple drafts model of consciousness presented in “Consciousness Explained” (Dennett, 1991) and his other works. Daniel Dennett is a self-described illusionist (Dennett, 2016) and a functionalist. His position is synonymous to holding self-conscious experiences, such as deliberating over one’s pain or reflecting over one’s actions insufficient to postulate existence of a metaphysical self. He believes instead that experiences are functional realizations which do not require any self, and the feeling of being conscious or self-conscious is actually a ”user-illusion” (Dennett, 1991), a term describing the unjustified belief of being in control of one’s actions. In his views, a selfhood as it is popularly conceived is contradictory. Therefore, he rejects realism about mental events, a position also called naïve realism (Siegel, 2011), on the basis that it is unverifiable and there are insufficient grounds to accept mental events (Dennett, 1988). He adopts a similar scepticism towards other theories of minds, hence nearing eliminative materialism in self-consciousness and related theme of pain (Dennett, 1978). His multiple drafts model of consciousness seeks to ground our beliefs about self-consciousness in the specific architecture of mind, which is particular to every species and kind of being. As such it is a particularly flexible theory that examines experiences of non-humans without falling into binary thinking – believing that a being has as rich inner life as humans do or none. This is why it is a great starting point for establishing necessary conditions for consciousness in robots. In this essay, I will often use words computer, programme, robot interchangeably for the purpose of clarity and take as the working definition “autonomous machines capable of sensing their environment, making decision and performing tasks similar to human actions”. I chose to explore self-consciousness instead of committing to the issue of consciousness, because consciousness can be defined in a weak sense, in which even a thermostat is “conscious” of the temperature, and consciousness in a strong sense, which invokes the internalism and externalism debate that is less connected to the nature of experiences than self-consciousness. My exploration pertains first and foremost to the philosophy of mind, of which I will examine the most relevant positions and decide to commit to functionalism (Block, 1980). Then I will advocate for explaining away of some of phenomena of self-consciousness and believing self-consciousness to be a sort of illusion. From there I will conclude that robots could fall for the same illusion of self-consciousness and therefore become self-conscious. I will argue, that self-consciousness can be established using a modified Turing Test, which would determine if a robot believed in a meaningful narrative about itself (Ricoeur, 1991) and hence be self-conscious. This will lead to answering the question of this essay: what are the features necessary for a self-conscious robot in the light of “Consciousness Explained” by Daniel Dennett? (shrink)

We provide a logical matrix semantics and a Gentzen-style sequent calculus for the first-degree entailments valid in W. T. Parry’s logic of Analytic Implication. We achieve the former by introducing a logical matrix closely related to that inducing paracomplete weak Kleene logic, and the latter by presenting a calculus where the initial sequents and the left and right rules for negation are subject to linguistic constraints.

A thesis (“weak BCP”) nearly universally held among philosophers of probability connects the concepts of objective chance and metaphysical modality: Any prospect (outcome) that has a positive chance of obtaining is metaphysically possible—(nearly) equivalently, any metaphysically impossible prospect has zero chance. Particular counterexamples are provided utilizing the monotonicity of chance, one of them related to the four world paradox. Explanations are offered for the persistent feeling that there cannot be chancy metaphysical necessities or chancy metaphysical impossibilities. Chance is objective but (...) contrary to popular opinion it is also largely epistemic. Chancy necessities are analogous to necessary a posteriori truths.

In the article I discuss functionalist interpretations of Husserlian phenomenology. The first one was coined in the discussion between Hubert Dreyfus and Ronald McIntyre. They argue that Husserl’s phenomenology shares similarities with computational functionalism, and the key similarity is between the concept of noema and the concept of mental representation. I show the weaknesses of that reading and argue that there is another available functionalist reading of Husserlian phenomenology. I propose to shift perspective and approach the relation between phenomenology and (...) functionalism from a methodological perspective, specifically taking into account the functionalist explanatory strategy called functional analysis. I discuss the notion of function in Husserl’s works and Husserl’s idea of functional phenomenology. The key argument I develop is that in functional phenomenology we can find an explanatory strategy which is analogous to the strategy of functional decomposition used in functional analysis. I conclude that the proposed functionalist reading of phenomenology opens a new approach to the integration of phenomenology with cognitive sciences. (shrink)

In ‘What Has Philosophy to Learn from Tort Law?’, Bernard Williams reaffirms J. L. Austin’s suggestion that philosophy might learn from tort law ‘the difference between practical reality and philosophical frivolity’. Yet while Austin regarded tort law as just another repository of time-tested concepts, on a par with common sense as represented by a dictionary, Williams argues that ‘the use of certain ideas in the law does more to show that those ideas have strength than is done by the mere (...) fact that they are part of the currency of common sense’. But what does it mean to show that ideas or concepts ‘have strength’? How does conceptual strength relate to the distinction between practical reality and philosophical frivolity? And what special features of the law are supposed to make it a better test of conceptual strength than common sense? In this chapter, I reconstruct and develop Williams’s answers to these questions. I show why Williams believes that we need to test the concepts forming the currency of common sense against practical reality as embodied by legal practice; I identify seven features of tort law that make it particularly suitable to act as such a test; I distinguish three respects in which concepts can show strength, and unpack Williams’s metaphor of microwave-resistant concepts: concepts capable of holding and presenting material for intense critical scrutiny without succumbing to it themselves; lastly, I show how philosophy can learn to identify systematically weak concepts, and the limits of otherwise valuable concepts, by considering which concepts fail the test.

The aim of this chapter is to analyse the concept of love —understood in the broad and Christian-inspired sense of love as agape-charis love— in relation to the animes Dragon Ball and Dragon Ball Z. I first comment on the character of Piccolo —and how his friendship with Son Gohan— leads to him losing all his original villainous traits. I argue that the evolution of the character of Piccolo through his friendship with Son Gohan illustrates the philosophical claim that a (...) loving and giving of oneself to the other —far from being a sign of weakness— is a courageous and self-affirming exercise. The result may move the individual to an inner transformative experience that leads to the enjoyment of a renewed and authentic life that is worth living. I then argue that Son Goku’s respectful attitude towards his opponents is ultimately a loving attitude. Last, I argue that it is the inspiring and loving example of Son Goku that ultimately explains why characters such as Vegeta —who are at first presented as villains— end up losing their villainous traits after fighting against Son Goku.

Contemporary philosophers nearly unanimously endorse knowledge reliabilism, the view that knowledge must be reliably produced. Leading reliabilists have suggested that reliabilism draws support from patterns in ordinary judgments and intuitions about knowledge, luck, reliability, and counterfactuals. That is, they have suggested a proto-reliabilist hypothesis about “commonsense” or “folk” epistemology. This paper reports nine experimental studies (N = 1262) that test the proto-reliabilist hypothesis by testing four of its principal implications. The main findings are that (a) commonsense fully embraces the possibility (...) of unreliable knowledge, (b) knowledge judgments are surprisingly insensitive to information about reliability, (c) “anti-luck” intuitions about knowledge have nothing to do with reliability specifically, and (d) reliabilists have mischaracterized the intuitive counterfactual properties of knowledge and their relation to reliability. When combined with the weakness of existing arguments for reliabilism and the recent emergence of well supported alternative views that predict the widespread existence of unreliable knowledge, the present findings are the final exhibit in a conclusive case for abandoning reliabilism in epistemology. I introduce an alternative theory of knowledge, abilism, which out-performs reliabilism and well explains all the available evidence. (shrink)

This paper argues that the innovation of an ordering source parameter in the standard Lewis-Kratzer semantics for modals was a mistake, at least for English auxiliaries like ‘ought’, and that a simpler dyadic semantics (as proposed in my earlier work) provides a superior account of normative uses of modals. I programmatically investigate problems arising from (i) instrumental conditionals, (ii) gradability and “weak necessity”, (iii) information-sensitivity, and (iv) conflicts, and show how the simpler semantics provides intuitive solutions given three basic moves: (...) (1) an end-relational analysis of normative modality, (2) a “most” analysis of “weak necessity”, and (3) well-motivated appeals to pragmatics. I conclude with metasemantic observations about the desiderata for a semantics for ‘ought’. (shrink)

This article is about relations of support and conflict within systems of fundamental legal rights—and the arguments for and against rights that those relations make possible. Justificatory linkage arguments defend controversial rights by claiming that they provide very useful support to the realisation of well-accepted rights. This article analyses such arguments in detail and discusses their structures, uses and pitfalls. It then shows that linkage arguments can be used not just to defend rights, but also to attack them. When rights (...) conflict—whether severely or weakly, logically or practically—negative linkage arguments attacking them can be based on the trouble they make for other rights. Many examples of conflicts of rights are provided. Negative linkage arguments provide reasons for rejecting, repealing or trimming the criticised right. Such arguments are already in regular use, but their c. (shrink)

This paper addresses a difficult passage from Aristotle’s Metaphysics (V. 4, 1015a11-13) in which he identifies a metaphorical use of the term “nature” (phusis) to refer to the entities which he calls “substances” (ousiai). I claim that the passage at stake deploys the very notion of metaphor on the basis of an analogy (as defined in the Poetics and in the Rhetorics), which is grounded on a weak (and, sometimes, very weak) similarity between two relations (each involving two relata). The (...) sentences found in 1015a11-13 belong to those kind of metalinguistic sentences which we usually employ to shed some light on the metaphorical use of a term. The similarity Aristotle is presupposing is this: both nature and substance are, in their respective fields, some kind of principle that guarantees (besides other things) certain persistence conditions for what they are the principles of. And this weak similarity is enough for the term “nature” to refer metaphorically to substances. (shrink)

Abstract. The aim of this paper is to present a topological method for constructing discretizations (tessellations) of conceptual spaces. The method works for a class of topological spaces that the Russian mathematician Pavel Alexandroff defined more than 80 years ago. Alexandroff spaces, as they are called today, have many interesting properties that distinguish them from other topological spaces. In particular, they exhibit a 1-1 correspondence between their specialization orders and their topological structures. Recently, a special type of Alexandroff spaces was (...) used by Ian Rumfitt to elucidate the logic of vague concepts in a new way. According to his approach, conceptual spaces such as the color spectrum give rise to classical systems of concepts that have the structure of atomic Boolean algebras. More precisely, concepts are represented as regular open regions of an underlying conceptual space endowed with a topological structure. Something is subsumed under a concept iff it is represented by an element of the conceptual space that is maximally close to the prototypical element p that defines that concept. This topological representation of concepts comes along with a representation of the familiar logical connectives of Aristotelian syllogistics in terms of natural settheoretical operations that characterize regular open interpretations of classical Boolean propositional logic. In the last 20 years, conceptual spaces have become a popular tool of dealing with a variety of problems in the fields of cognitive psychology, artificial intelligence, linguistics and philosophy, mainly due to the work of Peter Gärdenfors and his collaborators. By using prototypes and metrics of similarity spaces, one obtains geometrical discretizations of conceptual spaces by so-called Voronoi tessellations. These tessellations are extensionally equivalent to topological tessellations that can be constructed for Alexandroff spaces. Thereby, Rumfitt’s and Gärdenfors’s constructions turn out to be special cases of an approach that works for a more general class of spaces, namely, for weakly scattered Alexandroff spaces. This class of spaces provides a convenient framework for conceptual spaces as used in epistemology and related disciplines in general. Alexandroff spaces are useful for elucidating problems related to the logic of vague concepts, in particular they offer a solution of the Sorites paradox (Rumfitt). Further, they provide a semantics for the logic of clearness (Bobzien) that overcomes certain problems of the concept of higher2 order vagueness. Moreover, these spaces help find a natural place for classical syllogistics in the framework of conceptual spaces. The crucial role of order theory for Alexandroff spaces can be used to refine the all-or-nothing distinction between prototypical and nonprototypical stimuli in favor of a more fine-grained gradual distinction between more-orless prototypical elements of conceptual spaces. The greater conceptual flexibility of the topological approach helps avoid some inherent inadequacies of the geometrical approach, for instance, the so-called “thickness problem” (Douven et al.) and problems of selecting a unique metric for similarity spaces. Finally, it is shown that only the Alexandroff account can deal with an issue that is gaining more and more importance for the theory of conceptual spaces, namely, the role that digital conceptual spaces play in the area of artificial intelligence, computer science and related disciplines. Keywords: Conceptual Spaces, Polar Spaces, Alexandroff Spaces, Prototypes, Topological Tessellations, Voronoi Tessellations, Digital Topology. (shrink)

Hobbs (2010) introduced ‘clause-internal coherence’ (CIC) to describe inferences in, e.g., ‘A jogger was hit by a car,’ where the jogging is understood to have led to the car-hitting. Cohen & Kehler (2021) argue that well-known pragmatic tools cannot account for CIC, motivating an enrichment account familiar from discourse coherence research. An outstanding question is how to compositionally derive CIC from coherence relations. This paper takes strides in answering this question. It first provides experimental support for the existence of CIC (...) via offline evidence that attributive (non-)deverbal adjectives can trigger the same causal inferences within clauses that their predicative counterparts can trigger across clauses, albeit more weakly. To explain the experimental results, we use tools in Segmented Discourse Representation Theory (SDRT), which allows us to show that causal inferences can be derived in various ways, depending on whether deverbal adjectives are used attributively or predicatively. If the former, they are presupposition triggers and the coherence relations Elaboration/Continuation compete with Background; if the latter, Explanation/Result compete with Background. These different competitions -- cashed out in terms of interaction between default axioms -- correlate with the difference in the relative salience of the causal inferences. (shrink)
