I offer you some theories of intellectual obligations and rights (virtue Ethics): initially, RBT (a Right to Believe Truth, if something is true it follows one has a right to believe it), and, NDSM (one has no right to believe a contradiction, i.e., No right to commit Doxastic Self-Mutilation). Evidence for both below. Anthropology, Psychology, computer software, Sociology, and the neurosciences prove things about human beliefs, and History, Economics, and comparative law can provide evidence of value about theories of rights. (...) However, insofar as we have methods within Philosophy to help us formulate precise concepts of 'belief' and 'rights', methods that also help us to prove links (or absence thereof) amongst families of concepts of rights and belief, our discipline is in and of itself capable of sound reasoning about issues as puzzling as the following. Suppose a Jane who does not believe in God yet who believes she ought to so believe: Jane is undergoing doxastic moral regret (moral regret for lack of faith). We have all known such Janes and perhaps at one time or another even been one. Paradox: given RBT and NDSM, Jane as described not only does not exist, Jane cannot exist. Thus, to enrich the ways in which Philosophy need not get all its evidence from other academic disciplines, I present a brief introduction to what I call Neutral Universal Frames (NUFs). NUFs solve hard puzzles about interactions among modal concepts of belief and rights, concepts that occur in RBT, NDSM and the description of our Janes. NUFs for theories precisely articulated via any two or more modal concepts are a powerful and immensely general set of tools enabling us to define rich theories of truth ("models on frames") to test philosophical theories for internal consistency and to prove the existence of connections (or absence thereof) amongst alternative articulations of philosophical theories. NUFs thereby add to the constructive knowledge producing way Logics intersect with Philosophy of Religion. And we will soon see why Jane, be she named 'Jane' or known simply as you: cannot exist. Read on at your own risk. (shrink)

Translation of Aristotle's Parts of Animals Book I into Portuguese, with full commentaries.

The goal of this paper is to review and critically discuss the philosophical aspects of probabilistic seismic hazard analysis (PSHA). Given that estimates of seismic hazard are typically riddled with uncertainty, diferent epistemic values (related to the pursuit of scientifc knowledge) compete in the selection of seismic hazard models, in a context infuenced by non-epistemic values (related to practical goals and aims) as well. We frst distinguish between the diferent types of uncertainty in PSHA. We claim that epistemic and nonepistemic (...) considerations are closely related in the selection of the appropriate estimate of seismic hazard by the experts. Finally, we argue that the division of scientifc responsibility among the experts can lead to responsibility gaps. This raises a problem for the ownership of the results (“no one’s model” problem) similar to the “problem of many hands” in the ethics of technology. We conclude with a plea for a close collaboration between philosophy and engineering. (shrink)

This book discusses Aristotle’s notions of essence and substance as they are developed in Metaphysics ZH. I examine Aristotle's argument at length and defends an unorthodox interpretation according to which his motivation is to provide an answer against a conflation between criteria for existential priority (delivering substances as primary beings) and criteria for explanatory priority (delivering essences as primary principles).

Lockean approaches to property take it that persons can unilaterally acquire private ownership over hitherto unowned resources. Such natural law accounts of property rights are often thought to be of limited use when dealing with the complexities of natural resource use outside of the paradigm of private ownership of land for agricultural or residential development. The tragedy of the commons has been shown to be anything but an inevitability, and yet Lockeanism seems to demand that even the most robust common (...) property arrangements be converted to privatized units. This often motivates a move away from natural law in the moral analysis of property rights. I argue however that it is not the deontological nature of Lockean principles that are at fault, but rather the manner of their application. Lockean theory often exhibits a bias in favour of private property: assuming that only private property can protect one’s interest in autonomy, and therefore asserting that each individual has a power of private acquisition. Starting with a claim against interference however enables us to mould the appropriate property rights to each individual’s particular interest in autonomy. This sometimes leads to private ownership, but often leads to various forms of commons. (shrink)

The aim of this paper is to clarify under what conditions a philosophical problem arises. I will describe two ways in which we might perceive a question as a problem. First, when we fnd ourselves inclined to believe in propositions that appear incompatible with each other. Second, when we fnd ourselves inclined to believe in propositions that seem incompatible with our desires. I will discuss both of these cases and articulate a didactic strategy – the Clash Strategy – which can (...) be used in order to plan and facilitate dialogic inquiry in the classroom. This strategy suggests introducing stimuli that will help students appreciate the clash that drives the philosophical question to be explored during the dialogue. In summary, this paper aims to ofer insights to all teachers interested in promoting dialogic inquiry, whether philosophical or otherwise, in education. (shrink)

This book gives an account of a full spectrum of property rights and their relationship to individual liberty. It shows that a purely deontological approach to justice can deal with the most complex questions regarding the property system. Moreover, the author considers the economic, ecological, and technological complexities of our real-world property systems. The result is a more conceptually sound account of natural rights and the property system they demand. If we think that liberty should be at the centre of (...) justice, what does that mean for the property system? Economists and lawyers widely agree that a property system must be composed of many different types of property: the kind of private ownership one has over one's person and immediate possessions, as well as the kinds of common ownership we each have in our local streets, as well as many more. However, theories of property and justice have not given anything approaching an adequate account of the relationship between liberty and any other form of property other than private ownership. It is often thought that a basic commitment to liberty cannot really tell us how to arrange the major complexities of the property system, which diverge from simple private ownership. Property and Justice demonstrates how philosophical rigour coupled with interdisciplinary engagement enables us to think clearly about how to deal with real-world problems. It will be of interest to political philosophers, political theorists, and legal theorists working on property rights and justice. (shrink)

Hillel Steiner argues that a necessary and sufficient condition for the compossibility of a set of rights is that those rights be extensionally differentiable. However, given that two or more actions can extensionally overlap without thereby being mutually unperformable, if such actions are specified in the relevant rights, then those rights will not be incompossible, notwithstanding their extensional overlap. The set of compossible sets of rights then is greater than the subset of extensionally differentiable rights, and extensional differentiability is a (...) sufficient but unnecessary condition of compossibility.

Judgments concerning animals have arisen across a variety of established practice areas. There is, however, no publicly available repository of judgments concerning the emerging practice area of animal protection law. This has hindered the identification of individual animal protection law judgments and comprehension of the scale of animal protection law made by courts. Thus, we detail the creation of an initial animal protection law repository using natural language processing and machine learning techniques. This involved domain expert classification of 500 judgments (...) according to whether or not they were concerned with animal protection law. 400 of these judgments were used to train various models, each of which was used to predict the classification of the remaining 100 judgments. The predictions of each model were superior to a baseline measure intended to mimic current searching practice, with the best performing model being a support vector machine (SVM) approach that classified judgments according to term frequency—inverse document frequency (TF-IDF) values. Investigation of this model consisted of considering its most influential features and conducting an error analysis of all incorrectly predicted judgments. This showed the features indicative of animal protection law judgments to include terms such as ‘welfare’, ‘hunt’ and ‘cull’, and that incorrectly predicted judgments were often deemed marginal decisions by the domain expert. The TF-IDF SVM was then used to classify non-labelled judgments, resulting in an initial animal protection law repository. Inspection of this repository suggested that there were 175 animal protection judgments between January 2000 and December 2020 from the Privy Council, House of Lords, Supreme Court and upper England and Wales courts.

We are becoming increasingly dependent on robots and other forms of artificial intelligence for our beliefs. But how should the knowledge gained from the “say-so” of a robot be classified? Should it be understood as testimonial knowledge, similar to knowledge gained in conversation with another person? Or should it be understood as a form of instrument-based knowledge, such as that gained from a calculator or a sundial? There is more at stake here than terminology, for how we treat objects as (...) sources of knowledge often has important social and legal consequences. In this paper, I argue that at least some robots are capable of testimony. I make my argument by exploring the differences between instruments and testifiers on a well-known account of knowledge: reliabilism. On this approach, I claim that the difference between instruments and testifiers as sources of knowledge is that only the latter are capable of deception. As some robots can be designed to deceive, so they too should be recognized as testimonial sources of knowledge. (shrink)

Does metacognition--the capacity to self-evaluate one's cognitive performance--derive from a mindreading capacity, or does it rely on informational processes? Joëlle Proust draws on psychology and neuroscience to defend the second claim. She argues that metacognition need not involve metarepresentations, and is essentially related to mental agency.

Over the centuries the term “talent” has changed semantically and slowly transformed itself into a floating signifier or become an accidental designator. The term “talent” no longer has one single meaning and a “referent” in real life, but instead a multiplicity of meaning and references to something beyond real life, something indefinite and indefinable. In other words, today we do not know specifically what the term “talent” in talent management really means or refers to. Indeed, this is problematical, because in (...) late modernity the term “talent” has become a popular and frequently used key term among business consultants and, within the science of human resource management, a cornerstone in the discipline of “talent management”, and not knowing what the term really means will turn any talent discussion, talent identification and talent recruitment into a question of subjectivity and belief in talent rather than objectivity and knowledge of talent.

This edited collection offers a critical appreciation of talent management in contrast to the extensive literature adopting mainstream approaches to the topic. The authors explore fundamental questions in the field to better understand why managing talent seems so attractive as a management practice, the meaning of talent, and how talent is recognised in organisations. The mix of conceptual and empirical chapters in the book teases out some critical perspectives that will provoke thought and reflection among practitioners and stimulate ideas for (...) new research topics and approaches. The diverse contributions presented in this book will undoubtedly be of use to academics, practitioners and postgraduate students of human resource management. (shrink)

Billy Dunaway develops and defends a framework for realism about morality. He defends the idea that moral properties are privileged parts of reality which are the referents for our moral terms. He suggests how it is that we can know about morality, and what the limits to moral disagreement are.

This is an introductory handbook for some of the main themes around the notion of predication in Aristotle. It does not aim at being exhaustive, but only sketches some important lines about the subject; it contains an introductory essay, besides the translation (into Portuguese) and commentary of basic texts (such as Posterior Analytics I-22, Categories 1-5, Interpretation 1-6 etc.).

This new study provides a refreshing look at the issue of exceptions and shows that much of the problem stems from a failure to recognize at least two kinds of exception-ridden law: ceteris paribus laws and ideal laws. Billy Wheeler offers the first book-length discussion of ideal laws. The key difference between these two kinds of laws concerns the nature of the conditions that need to be satisfied and their epistemological role in the law’s formulation and discovery. He presents (...) a Humean-inspired approach that draws heavily on concepts from the information and computing sciences. Specifically, Wheeler argues that laws are best seen as algorithms for compressing empirical data and that ideal laws are needed as 'lossy compressors' for complex data. Major figures in the metaphysics of science receive special attention such as Ronald Giere, Bas van Fraassen, Nancy Cartwright, David Lewis and Marc Lange. This book is essential reading for philosophers of science and will interest metaphysicians, epistemologists and others interested in applying concepts from computing to traditional philosophical problems.

Translation of Aristotle's Posterior Analytics I into Portuguese, with a few notes, experimental glossary and introduction. The translation, which was made at 2003/4, was preliminary and its publication was intended to provide a didactic tool for courses as well as a provisional resource in research seminars. It needs some revision. I am currently working (slowly...) on the revision of the translation and a new revised one will surely appear at some point.

Many libertarians ground their theory of justice in a non-aggression principle. The NAP is often the basis for the libertarian condemnation of state action – that it is necessarily aggressive and therefore unjust. This approach is often criticised insofar as it defines aggression, in part, as the violation of legitimate property rights, and is therefore parasitical upon a prior – and unjustified – theory of property. While it is true that libertarians who defend the NAP sometimes fail to give a (...) satisfactory account of its relationship to libertarian property rights, such an account is in fact available. A commitment to property rights and to non-aggression can both be grounded in a commitment to non-interference. Such a principle, then, brings together the NAP and the theory of property it is parasitical upon, thus saving the unity and austerity of the overall approach. (shrink)

Translation of Aristotle's Metaphysics IV and VI, with notes. The translation is preliminary and intended as a provisional teaching tool to be also used in seminars and discussions with peers in order to reach a more elaborated version.

There are many cases in which, by making some great sacrifice, you could bring about either a good outcome or a very good outcome. In some of these cases, it seems wrong for you to bring about the good outcome, since you could bring about the very good outcome with no additional sacrifice. It also seems permissible for you not to make the sacrifice, and bring about neither outcome. But together, these claims seem to imply that you ought to bring (...) about neither outcome rather than the good outcome. And that seems very counterintuitive. In this paper, I develop this problem, propose a solution, and then draw out some implications both for how we should understand supererogation and for how we should approach charitable giving.

Among those living systems, which are cognizers? Among the behaviours of, and causes of behaviour in, living systems, which are cognitive? Such questions sit at the heart of a sophisticated, ongoing debate, of which the recent papers by Corcoran et al. ( 2020 ) and Sims and Kiverstein ( 2021 ) serve as excellent examples. I argue that despite their virtues, both papers suffer from flawed conceptions of the point of the debate. This leaves their proposals ill-motivated—good answers to the (...) wrong question. Additionally, their proposals are unfit to serve the legitimate roles for characterizations of cognition. (shrink)

This paper looks at the phenomenon of ethical vagueness by asking the question, how ought one to reason about what to do when confronted with a case of ethical vagueness? I begin by arguing that we must confront this question, since ethical vagueness is inescapable. I then outline one attractive answer to the question: we ought to maximize expected moral value when confronted with ethical vagueness. This idea yields determinate results for what one rationally ought to do in cases of (...) ethical vagueness. But what it recommends is dependent on which substantive theory of vagueness is true; one can't draw conclusions about how to reason about vagueness in ethics in the absence of concrete assumptions about the nature of vagueness.
