We present and show topological completeness for LB, the logic of the topological border. LB is also a logic of epistemic ignorance. Also, we present and show completeness for LUT, the logic of unknown truths. A simple topological completeness proof for S4 is also presented using a T1 space.

We introduce an operator to represent the simple notion of being wrong. Read Wp to mean: the agent is wrong about p . Being wrong about p means believing p though p is false. We add this operator to the language of propositional logic and study it. We introduce a canonical model for logics of being wrong, show completeness for the minimal logic of being wrong and various other systems. En route we examine the expressiveness of the language. In conclusion, (...) we discuss an open question regarding K4. (shrink)

In this highly original text, Christopher Steinsvold explores an alternative semantics for logics of rational belief. Topologies, as mathematical objects, are typically interpreted in terms of space; here topologies are re-interpreted in terms of an agent with rational beliefs. The topological semantics tells us that the agent can never, in principle, know everything; that the agent's beliefs can never be complete. -/- A number of completeness proofs are given for a variety of logics of rational belief. Beyond this, (...) the author explores the philosophical question of why our beliefs can never be complete, and considers the possibility that a totality of truths is a dialethia. -/- This work will be of interest to all philosophers interested in epistemology, and modal logicians as well.

We show the Boxdot Conjecture holds for a limited but familiar range of Lemmon-Scott axioms. We re-introduce the language of essence and accident, first introduced by J. Marcos, and show how it aids our strategy.

Patrick Grim has presented arguments supporting the intuition that any notion of a totality of truths is incoherent. We suggest a natural semantics for various logics of belief which reflect Grim’s intuition. The semantics is a topological semantics, and we suggest that the condition can be interpreted to reflect Grim’s intuition. Beyond this, we present a natural canonical topological model for K4 and KD4.

Interpreting the diamond of modal logic as the derivative, we present a topological canonical model for extensions of K4 and show completeness for various logics. We also show that if a logic is topologically canonical, then it is relationally canonical.

Given the frequency of human error, it seems rational to believe that some of our own rational beliefs are false. This is the axiom of epistemic modesty. Unfortunately, using standard propositional quantification, and the usual relational semantics, this axiom is semantically inconsistent with a common logic for rational belief, namely KD45. Here we explore two alternative semantics for KD45 and the axiom of epistemic modesty. The first uses the usual relational semantics and bisimulation quantifiers. The second uses a topological semantics (...) and standard propositional quantification. We show the two different semantics validate many of the same formulas, though we do not know whether they validate exactly the same formulas. Along the way we address various philosophical concerns.

The Boxdot Conjecture is shown to hold for a novel class of modal systems. Each system in this class is K plus an instance of a natural generalization of the McKinsey axiom.

A message appears on the moon. It is legible from Earth, and almost no one knows how it was created. Markus West leads the government’s investigation to find the creator. -/- The message is simple and familiar. But those three words, written in blazing crimson letters on the lunar surface, will foster the strangest revolution humankind has ever endured and make Markus West wish he was never involved. -/- The message is ‘Drink Diet Coke.’ -/- When Coca-Cola denies responsibility, global (...) annoyance becomes indignation. And when his investigation confirms Coca-Cola’s innocence, Markus West becomes one of the most hated men on Earth. -/- Later, five miles above the White House, a cylinder is discovered floating in the night. It is 400 feet tall, 250 feet in diameter, and exactly resembles a can of Campbell’s Chicken Noodle Soup. Nearly everyone thinks the cylinder is a promotional stunt gone wrong, just like the lunar advertisement. And this is exactly what the alien in the cylinder wants people to think. -/- Ralph, an eccentric extraterrestrial who’s been hiding on the moon, needs Markus’s help to personally deliver a dark warning to the White House. Ralph has a big heart, a fetish for Andy Warhol, and a dangerous plan to save the world. (shrink)

In an age where issues like climate change and the unintended consequences of technological innovation are high on the ethical and political agenda, questions about the nature and extent of our responsibilities to future generations have never been more important, yet simultaneously so difficult to answer. This book takes a unique approach to the problem by drawing on diverse traditions of thinking about care (including developmental psychology, phenomenology and feminist ethics) to explore the nature and meaning of our relationship with (...) the future. Demonstrating that many influential perspectives on intergenerational ethics, including positions advanced by John Rawls, Brian Barry, and Ulrich Beck are undermined by problems relating to uncertainty, it shows that an approach based on care ethics can confront the uncertain future successfully and give a viable account of the nature and scope of future-oriented responsibilities.

Fiction and truth : ancient stories about Pythagoras -- In search of the historical Pythagoras -- The Pythagorean secret society -- Thinkers influenced by Pythagoras and his pupils.

Suppose we believe that God created the world. Then surely we want it to be the case that he intended, in some sense at least, to create THIS world. Moreover, most theists want to hold that God didn't just guess or hope that the world would take one course or another; rather, he KNEW precisely what was going to take place in the world he planned to create. In particular, of each person P, God knew that P was to exist. (...) Call this the "standard" conception. Most theists find the standard conception appealing. Unfortunately, the view seems to conflict with the equally appealing idea — call it "temporal actualism" — that there are no "future" individuals beyond those that already exist in the present moment. For, on this view, for any historical person P, prior to creation, there was no such person as P and hence nothing about P for God to know. Hence, in particular, God couldn't have known that P was to exist. This is of course not a new problem. But past solutions to it are highly problematic. In this paper, after canvassing previous approaches, I will propose a solution that seems to preserve both temporal actualism and a suitably robust form of the standard conception while avoiding the pitfalls of the past.

Plato's Utopia Recast is an illuminating reappraisal of Plato's later works, which reveals radical changes in his ethical and political theory. Christopher Bobonich examines later dialogues, with a special emphasis upon the Laws, and argues that in these late works, Plato both rethinks and revises the basic ethical and poltical positions that he held in his better-known earlier works, such as the Republic. This book will change our understanding of Plato. His controversial moral and political theory, so influential in (...) Western thought, will henceforth be seen in a new light. (shrink)

In apparent motion experiments, participants are presented with what is in fact a succession of two brief stationary stimuli at two different locations, but they report an impression of movement. Philosophers have recently debated whether apparent motion provides evidence in favour of a particular account of the nature of temporal experience. I argue that the existing discussion in this area is premised on a mistaken view of the phenomenology of apparent motion and, as a result, the space of possible philosophical (...) positions has not yet been fully explored. In particular, I argue that the existence of apparent motion is compatible with an account of the nature of temporal experience that involves a version of direct realism. In doing so, I also argue against two other claims often made about apparent motion, viz. that apparent motion is the psychological phenomenon that underlies motion experience in the cinema, and that apparent motion is subjectively indistinguishable from real motion.

The paper argues that an account of understanding should take the form of a Carnapian explication and acknowledge that understanding comes in degrees. An explication of objectual understanding is defended, which helps to make sense of the cognitive achievements and goals of science. The explication combines a necessary condition with three evaluative dimensions: An epistemic agent understands a subject matter by means of a theory only if the agent commits herself sufficiently to the theory of the subject matter, and to (...) the degree that the agent grasps the theory (i.e., is able to make use of it), the theory answers to the facts and the agent’s commitment to the theory is justified. The threshold for outright attributions of understanding is determined contextually. The explication has descriptive as well as normative facets and allows for the possibility of understanding by means of non-explanatory (e.g., purely classificatory) theories. (shrink)

Recognizing that truth is socially constructed or that knowledge and power are related is hardly a novelty in the social sciences. In the twenty-first century, however, there appears to be a renewed concern regarding people’s relationship with the truth and the propensity for certain actors to undermine it. Organizations are highly implicated in this, given their central roles in knowledge management and production and their attempts to learn, although the entanglement of these epistemological issues with business ethics has not been (...) engaged as explicitly as it might be. Drawing on work from a virtue epistemology perspective, this paper outlines the idea of a set of epistemic vices permeating organizations, along with examples of unethical epistemic conduct by organizational actors. While existing organizational research has examined various epistemic virtues that make people and organizations effective and responsible epistemic agents, much less is known about the epistemic vices that make them ineffective and irresponsible ones. Accordingly, this paper introduces vice epistemology, a nascent but growing subfield of virtue epistemology which, to the best of our knowledge, has yet to be explicitly developed in terms of business ethics. The paper concludes by outlining a business ethics research agenda on epistemic vice, with implications for responding to epistemic vices and their illegitimacy in practice. (shrink)

Christopher Hookway presents a series of essays on the work of Charles Sanders Peirce (1839-1913), the 'founder of pragmatism' and one of the most important and original American philosophers.

"These notes are about the process of design: the process of inventing things which display new physical order, organization, form, in response to function." This book, opening with these words, presents an entirely new theory of the process of design. In the first part of the book, Christopher Alexander discusses the process by which a form is adapted to the context of human needs and demands that has called it into being. He shows that such an adaptive process will (...) be successful only if it proceeds piecemeal instead of all at once. It is for this reason that forms from traditional un-self-conscious cultures, molded not by designers but by the slow pattern of changes within tradition, are so beautifully organized and adapted. When the designer, in our own self-conscious culture, is called on to create a form that is adapted to its context he is unsuccessful, because the preconceived categories out of which he builds his picture of the problem do not correspond to the inherent components of the problem, and therefore lead only to the arbitrariness, willfulness, and lack of understanding which plague the design of modern buildings and modern cities. In the second part, Mr. Alexander presents a method by which the designer may bring his full creative imagination into play, and yet avoid the traps of irrelevant preconception. He shows that, whenever a problem is stated, it is possible to ignore existing concepts and to create new concepts, out of the structure of the problem itself, which do correspond correctly to what he calls the subsystems of the adaptive process. By treating each of these subsystems as a separate subproblem, the designer can translate the new concepts into form. The form, because of the process, will be well-adapted to its context, non-arbitrary, and correct. The mathematics underlying this method, based mainly on set theory, is fully developed in a long appendix. Another appendix demonstrates the application of the method to the design of an Indian village. (shrink)

Since 2023, the UK government's response to the “migrant crisis” has revolved around two controversial flagship policies: the deportation of asylum seekers to Rwanda, and the detention of migrants aboard a giant barge. In this short article, I examine the colonial and gendered dimensions of the two policies, finding them to be examples of the coloniality of gender. What this indicates, I suggest, is that the purpose of these policies is not merely to deter potential migrants—particularly LGBTQIA+ migrants—but also to (...) create a political narrative that allows the Conservative Party to garner right-wing votes by participating in high-profile culture wars; namely, the debate over transgender rights and the debate over how the UK should reckon with its imperial past.

Interactions between an intelligent software agent and a human user are ubiquitous in everyday situations such as access to information, entertainment, and purchases. In such interactions, the ISA mediates the user’s access to the content, or controls some other aspect of the user experience, and is not designed to be neutral about outcomes of user choices. Like human users, ISAs are driven by goals, make autonomous decisions, and can learn from experience. Using ideas from bounded rationality, we frame these interactions (...) as instances of an ISA whose reward depends on actions performed by the user. Such agents benefit by steering the user’s behaviour towards outcomes that maximise the ISA’s utility, which may or may not be aligned with that of the user. Video games, news recommendation aggregation engines, and fitness trackers can all be instances of this general case. Our analysis facilitates distinguishing various subcases of interaction, as well as second-order effects that might include the possibility for adaptive interfaces to induce behavioural addiction, and/or change in user belief. We present these types of interaction within a conceptual framework, and review current examples of persuasive technologies and the issues that arise from their use. We argue that the nature of the feedback commonly used by learning agents to update their models and subsequent decisions could steer the behaviour of human users away from what benefits them, and in a direction that can undermine autonomy and cause further disparity between actions and goals as exemplified by addictive and compulsive behaviour. We discuss some of the ethical, social and legal implications of this technology and argue that it can sometimes exploit and reinforce weaknesses in human beings. (shrink)

Schopenhauer is considered to be the most readable of German philosophers. This book gives a succinct explanation of his metaphysical system, concentrating on the original aspects of his thought, which inspired many artists and thinkers including Nietzsche, Wagner, Freud, and Wittgenstein. Schopenhauer's central notion is that of the will--a blind, irrational force that he uses to interpret both the human mind and the whole of nature. Seeing human behavior as that of a natural organism governed by the will to life, (...) Schopenhauer developed radical insights concerning the unconscious and sexuality which influenced both psychologists and philosophers. (shrink)

Philosophers of music often appeal to intuition to defend ontological theories of musical works. This practice is worrisome as it is rather unclear just how widely shared are the intuitions that philosophers appeal to. In this paper, I will first offer a brief overview of the debate over the ontology of musical works. I will argue that this debate is driven by a conflict between two seemingly plausible intuitions—the repeatability intuition and the creatability intuition—both of which may be defended on (...) the grounds that they are reflective of our actual musical practices. The problem facing philosophers within this debate is that there is no clear way to determine which of the two conflicting intuitions is more reflective of our musical practices. Finally, I offer discussion of an experimental study that was designed to test participants' intuitions regarding the repeatability of musical works. The evidence presented there suggests that the participants broadly accept the repeatability of musical works, but in a much narrower way than philosophers would likely accept. (shrink)

The authors outline a program for understanding the semantics and pragmatics of slur terms, proposing that slurs are mixed expressives that predicate membership in some social group G while simultaneously invoking a complex of historical facts and social attitudes about G. The authors then point to the importance of distinguishing between the potential offensive and derogatory effects of slur terms, with the former deriving from the impact on the listener of the invoked content itself, and the latter deriving from inferences (...) about speaker attitudes and intentions. The authors use the resulting framework to discuss several controversial cases of slurs and slurring: terms targeting political views such as ‘Nazi’ and ‘terf’, and cases in which non-slurs are used to derogate, as in cases of misgendering. The authors conclude that what counts as a slur is in part dependent on a background system of ideological assumptions, meaning that whether a particular term counts as a slur will depend in part on one’s ideological commitments and assumptions.

Moral judgments attempt to describe a reality that does not exist, so they are all false. This troubling view is known as the moral error theory. Christopher Cowie defends it against the most compelling counter-argument, the argument from analogy: Cowie shows that moral error theory does not compromise the practice of making epistemic judgments.

This chapter sets the scene for the subsequent philosophical discussions by surveying a number of biological interventions that have been used, or might in the future be used, for the purposes of crime prevention. These interventions are pharmaceutical interventions intended to suppress libido, treat substance abuse or attention deficit-hyperactivity disorder (ADHD), or modulate serotonin activity; nutritional interventions; and electrical and magnetic brain stimulation. Where applicable, we briefly comment on the historical use of these interventions, and in each case we discuss (...) the evidence that they are effective, or might become so with further refinement. The chapter concludes with a comment on some potentially significant differences between the varieties of intervention that we canvass. (shrink)

Christopher Bennett presents a theory of punishment grounded in the practice of apology, and in particular in reactions such as feeling sorry and making amends. He argues that offenders have a 'right to be punished' - that it is part of taking an offender seriously as a member of a normatively demanding relationship that she is subject to retributive attitudes when she violates the demands of that relationship. However, while he claims that punishment and the retributive attitudes are the (...) necessary expression of moral condemnation, his account of these reactions has more in common with restorative justice than traditional retributivism. He argues that the most appropriate way to react to crime is to require the offender to make proportionate amends. His book is a rich and intriguing contribution to the debate over punishment and restorative justice. (shrink)

Evolutionary developmental biology represents a paradigm shift in the understanding of the ontogenesis and evolutionary progression of the denizens of the natural world. Given the empirical successes of the evo-devo framework, and its now widespread acceptance, a timely and important task for the philosophy of biology is to critically discern the ontological commitments of that framework and assess whether and to what extent our current metaphysical models are able to accommodate them. In this paper, I argue that one particular model (...) is a natural fit: an ontology of dispositional properties coherently and adequately captures the crucial casual-cum-explanatory role that the fundamental elements of evo-devo play within that framework.

This paper presents a cross-cultural study on peoples’ negative attitude toward robots. 467 participants from seven different countries filled in the negative attitude towards robots scale survey which consists of 14 questions in three clusters: attitude towards the interaction with robots, attitude towards social influence of robots and attitude towards emotions in interaction with robots. Around one half of them were recruited at local universities and the other half was approached through Aibo online communities. The participants’ cultural background had a (...) significant influence on their attitude and the Japanese were not as positive as stereotypically assumed. The US participants had the most positive attitude, while participants from Mexico had the most negative attitude. The participants from the online community were more positive towards robots than those not involved. Previous experience in interacting with Aibo also had a positive effect, but owning an Aibo did not improve their attitude. (shrink)

Since the introduction of radio and television news, journalism has gone through multiple transformations, but each time it has been sustained by a commitment to basic values and best practices. Journalism Ethics is a reminder, a defense and an elucidation of core journalistic values, with particular emphasis on the interplay of theory, conceptual analysis and practice. The book begins with a sophisticated model for ethical decision-making, one that connects classical theories with the central purposes of journalism. Top scholars from philosophy, (...) journalism and communications offer essays on such topics as objectivity, privacy, confidentiality, conflict of interest, the history of journalism, online journalism, and the definition of a journalist. The result is a guide to ethically sound and socially justified journalism-in whatever form that practice emerges. Journalism Ethics will appeal to students and teachers of journalism ethics, as well as journalists and practical ethicists in general. (shrink)

The intuitive, folk concept of hypocrisy is not a unified moral category. While many theorists hold that all cases of hypocrisy involve some form of deception, I argue that this is not the case. Instead, I argue for a disjunctive account of hypocrisy whereby all cases of “hypocrisy” involve either the deceiving of others about the sincerity of an agent's beliefs or the lack of will to carry through with the demands of an agent's sincere beliefs. Thus, all cases of (...) hypocrisy can be described either as cases of deception or as cases of akrasia. If this analysis correct, then I suggest further that the moral status of all instances of hypocrisy must be reduced either to the moral blameworthiness of deception or to the moral blameworthiness of akrasia. There can be no unified account of the moral wrongness of “hypocrisy” that holds across the disjunction. (shrink)

The philosophy of pragmatism advances an evolutionary, learning-oriented perspective that is problem-driven, reflexive, and deliberative.

Although they are continually compositionally reconstituted and reconfigured, organisms nonetheless persist as ontologically unified beings over time – but in virtue of what? A common answer is: in virtue of their continued possession of the capacity for morphological invariance which persists through, and in spite of, their mereological alteration. While we acknowledge that organisms‟ capacity for the “stability of form” – homeostasis - is an important aspect of their diachronic unity, we argue that this capacity is derived from, and grounded (...) in a more primitive one – namely, the homeodynamic capacity for the “specified variation of form”. In introducing a novel type of causal power – a „structural power‟ – we claim that it is the persistence of their dynamic potential to produce a specified series of structurally adaptive morphologies which grounds organisms‟ privileged status as metaphysically “one over many” over time.

Can a player be held morally responsible for the choices that she makes within a videogame? Do the moral choices that the player makes reflect in any way on the player’s actual moral sensibilities? Many videogames offer players the options to make numerous choices within the game, including moral choices. But the scope of these choices is quite limited. I attempt to analyze these issues by drawing on philosophical debates about the nature of free will. Many philosophers worry that, if (...) our actions are predetermined, then we cannot be held morally responsible for them. However, Harry Frankfurt’s compatibilist account of free will suggests that an agent can be held morally responsible for actions that she wills, even if the agent is not free to act otherwise. Using Frankfurt’s analysis, I suggest that videogames represent deterministic worlds in which players lack the ability to freely choose what they do, and yet players can be held morally responsible for some of their actions, specifically those actions that the player wants to do. Finally, I offer some speculative comments on how these considerations might impact our understanding of the player’s moral psychology as it relates to the ethics of imagined fictional events.

_An Introduction to Philosophical Methods_ is the first book to survey the various methods that philosophers use to support their views. Rigorous yet accessible, the book introduces and illustrates the methodological considerations that are involved in current philosophical debates.

While eminently student-friendly, the book makes an important contribution to the debate regarding the acceptability of the various philosophical methods, and (...) so it will also be of interest to more experienced philosophers.

Dispositional properties are often referred to as ‘causal powers’, but what does dispositional causation amount to? Any viable theory must account for two fundamental aspects of the metaphysics of causation – the causal complexity and context sensitivity of causal interactions. The theory of mutual manifestations attempts to do so by locating the complexity and context sensitivity within the nature of dispositions themselves. But is this theory an acceptable first step towards a viable theory of dispositional causation? This paper argues that (...) the reconceptualization that the theory entails comes at too high a price, and is an unnecessary step in the wrong direction: these two central aspects concerning the metaphysics of causation can and should be accounted for in a dispositional account of causation without it.

We argue that while digital health technologies (e.g. artificial intelligence, smartphones, and virtual reality) present significant opportunities for improving the delivery of healthcare, key concepts that are used to evaluate and understand their impact can obscure significant ethical issues related to patient engagement and experience. Specifically, we focus on the concept of empowerment and ask whether it is adequate for addressing some significant ethical concerns that relate to digital health technologies for mental healthcare. We frame these concerns using five key (...) ethical principles for AI ethics (i.e. autonomy, beneficence, non-maleficence, justice, and explicability), which have their roots in the bioethical literature, in order to critically evaluate the role that digital health technologies will have in the future of digital healthcare.
