Purpose: This conceptual-epistemological paper deals with the old problem of inversion of thinking, as typified by traditional metaphysics-ontology. It is proposed that a thorough constructivism -- which views structures of mind, nature, and all, as not derived from (not referring to) any pre-structured given mind-independent reality (zero-derivation, 0-D) -- can go beyond this conceptual impasse; it can also serve as a fall-back position for positive ontologies. Practical implications: The practical result of 0-D is that all structures of (...) experience are understood as tools serving individual and collective subjects. Conclusion: This conceptual correction results in a simplification for the understanding of some conceptual puzzles, such as the mind-brain relation, but also in a considerable increase of responsibility, because entities and agents formerly considered responsible, and outside the mind, are recognized to be extensions of the subjects.

Formal methods are changing how epistemology is being studied and understood. A Critical Introduction to Formal Epistemology introduces the types of formal theories being used and explains how they are shaping the subject. Beginning with the basics of probability and Bayesianism, it shows how representing degrees of belief using probabilities informs central debates in epistemology. As well as discussing induction, the paradox of confirmation and the main challenges to Bayesianism, this comprehensive overview covers (...) objective chance, peer disagreement, the concept of full belief, and the traditional problems of justification and knowledge. Subjecting each position to a critical analysis, it explains the main issues in formal epistemology, and the motivations and drawbacks of each position. Written in an accessible language and supported study questions, guides to further reading and a glossary, positions are placed in an historic context to give a sense of the development of the field. As the first introductory textbook on formal epistemology, A Critical Introduction to Formal Epistemology is an invaluable resource for students and scholars of contemporary epistemology. (shrink)

This article deals with the theme of subjectivity. One of the most pressing questions today is what theoretical and practical efforts should be made to avoid being a powerless tool in the hands of others and under what conditions one’s own “subjective opinion” becomes the real, reliable fulcrum as far as purposeful activity, free and reasonable goal-setting are concerned. The desire to derive subjectivity from individual, singular existence today forces a thinker as prominent as Slavoj Žižek to search for (...) its form as “purified from” ideological layers and the contingencies of life. In his search for such a form, he turns to the psychoanalytic tradition, to the work of Jacques Lacan and his attempts to formalize the structures of subjectivity in isolation from the universality that generates them as necessity. This abstract consideration of subjectivity leads him to recognize subjectivity as a “distorting factor” in view of the insurmountable rupture between being and thinking. Evald Ilyenkov takes a different approach to the question of active self-determination. He conceives of personality as universal—the traits of a person are formed in the course of interaction between individuals in the process of producing the means of life. The individual becomes a personality or an acting subject, appropriating the generic powers of humanity, while being included in a system that implies a human relationship to the thing and, through it, to another individual.

The paper focuses on the review of current literature on formal philosophy. Special attention is paid to the review of the book «Introduction to Formal Philosophy» [Hansson, Hendricks, 2018]. The book is a consistent introduction to the problems of formal philosophy, a research tradition that relies on the precise mathematical tools in order to study traditional philosophical problems. The methods of formal philosophy are successfully applied not only to the problems of (...) ontology, epistemology and philosophy of language but also relevant for the problems of ethics, axiology and social philosophy. The book demonstrates that it is not correct to identify formal philosophy with another area of study – philosophical logic, since formal philosophy uses not only logical methods of analysis, but also uses the tools of game theory, decision theory, probability theory, Bayesian statistics, and other theories. Although the book has a propaedeutic character, it also contains some open problems. These problems include the aggregation of the opinions of the group under the condition of a conflicting base of premises in the theory of public choice, there are still open problems in the interpretation of Arrow’s impossibility theorem and others. Certainly, formalization in itself is not a general solution to the particular philosophical problem, but only a tool that allows to formulate a problem in a more rigorous and precise way, which sometimes allows to reveal some unexpected consequences, some implicit contradictions and new solutions. Despite the importance of the concept of coherence in ethics, decision theory, philosophy of law, Bayesian epistemology, philosophy of science, the existing formalizations of the concept of coherence are highly specialized for epistemology, researchers recognize the lack of the relevant explanatory models. Overall, the book is an excellent introduction in to the field of formal philosophy, which provides a general overview of different aspects of formal philosophy and the opportunity to study particular research topics by means of an extensive bibliography accompanying each of the chapters.

Belief Revision is a well-established field of research that deals with how agents rationally change their minds in the face of new information. The milestone of Belief Revision is a general and versatile formal framework introduced by Alchourrón, Gärdenfors and Makinson, known as the AGM paradigm, which has been, to this date, the dominant model within the field. A main shortcoming of the AGM paradigm, as originally proposed, is its lack of any guidelines for relevant change. To remedy (...) this weakness, Parikh proposed a relevance-sensitive axiom, which applies on splittable theories; i.e., theories that can be divided into syntax-disjoint compartments. The aim of this article is to provide an epistemological interpretation of the dynamics of splittable theories, from the perspective of Kuhn's inuential work on the evolution of scientific knowledge, through the consideration of principal belief-change scenarios. The whole study establishes a conceptual bridge between rational belief revision and traditional philosophy of science, which sheds light on the application of formal epistemological tools on the dynamics of knowledge.

The traditional picture of logic takes it for granted that "valid arguments have a fundamental epistemic significance", but neither model theory nor traditional proof theory dealing with formal system has been able to give an account of this significance. Since valid arguments as usually understood do not in general have any epistemic significance, the problem is to explain how and why we can nevertheless use them sometimes to acquire knowledge. It is suggested that we should distinguish (...) between arguments and acts of inferences and that we have to reconsider the latter notion to arrive at the desired explanation. More precisely, the notions should be developed so that the following relationship holds: one gets in possession of a ground for a conclusion by inferring it from premisses for which one already has grounds, provided that the inference in question is valid. The paper proposes explications of the concepts of ground and deductively valid inference so that this relationship holds as a conceptual truth. Logical validity of inference is seen as a special case of deductive validity, but does not add anything as far as epistemic significance is concerned—it resides already in the deductively valid inferences.

Policymakers who seek to make scientifically informed decisions are constantly confronted by scientific uncertainty and expert disagreement. This thesis asks: how can policymakers rationally respond to expert disagreement and scientific uncertainty? This is a work of non-ideal theory, which applies formal philosophical tools developed by ideal theorists to more realistic cases of policymaking under scientific uncertainty. I start with Bayesian approaches to expert testimony and the problem of expert disagreement, arguing that two popular approaches— supra-Bayesianism and the (...) standard model of expert deference—are insufficient. I develop a novel model of expert deference and show how it can deal with many of these problems raised for them. I then turn to opinion pooling, a popular method for dealing with disagreement. I show that various theoretical motivations for pooling functions are irrelevant to realistic policymaking cases. This leads to a cautious recommendation of linear pooling. However, I then show that any pooling method relies on value judgements, that are hidden in the selection of the scoring rule. My focus then narrows to a more specific case of scientific uncertainty: multiple models of the same system. I introduce a particular case study involving hurricane models developed to support insurance decision-making. I recapitulate my analysis of opinion pooling in the context of model ensembles, confirming that my hesitations apply. This motivates a shift of perspective, to viewing the problem as a decision theoretic one. I rework a recently developed ambiguity theory, called the confidence approach, to take input from model ensembles. I show how it facilitates the resolution of the policymaker’s problem in a way that avoids the issues encountered in previous chapters. This concludes my main study of the problem of expert disagreement. In the final chapter, I turn to methodological reflection. I argue that philosophers who employ the mathematical methods of the prior chapters are modelling. Employing results from the philosophy of scientific models, I develop the theory of normative modelling. I argue that it has important methodological conclusions for the practice of formal epistemology, ruling out popular moves such as searching for counterexamples. (shrink)

Communication is a crucial component of scientific activity (as of virtually any other domain of human activity, especially in this "communication age" in which we live). As researchers and as citizens, we should all be concerned with the communication of science as well as with communication within science. In this paper, I will deal with one of the key aspects of this topic ג€“ the question whether scientific communication is or should be ג€�transparentג€�. The view that (...) this is or should be the case is often taken for granted both by scientists and the general public. I will challenge this view and suggest that we should learn to live without the illusion that scientific communication is or should be transparent. This idea is closely related, if not derived from, the traditional epistemological conception according to which scientific method is the privileged tool we have for penetrating beyond appearances and discovering the true ג€�nature of thingsג€�, in terms of which all observable phenomena should be ultimately explained. Applying the scientific method should, thus, yield a fully intelligible representation of the world, which in its turn should be transparently communicable. The trouble with this enticing ideal is that it does not correspond to actual practice. Again and again we experience the fact that the ג€�true picture of the worldג€� remains veiled for everyone but a small group of initiated experts in a narrow domain. Is this only a technical problem having to do with the phenomenon of specialization and with the inevitable complexity of the language(s) of science, as it is often suggested? (shrink)

Background Decision-making competence is a complex concept in the care for transgender and gender diverse adolescents, since this type of care concerns one’s developing gender identity and involves treatment options that often lack international consensus. Even despite competence assessments, moral challenges arise in the decision-making process. Here, traditional forms of clinical ethics support such as moral case deliberation might not fit as these do not provide thematic guidance. This study therefore aimed to develop a practice-oriented ethics support tool to (...) assist care providers when dealing with moral challenges around decision-making competence in transgender adolescent care. Methods The study followed a participatory design to develop a tool in close collaboration with care providers; they had a say in all phases of development and dissemination. Firstly, nine care providers were interviewed about experienced moral challenges and needs for ethics support. Based on this, the structure and content of the tool was constructed and discussed in two focus group meetings, after which four care providers tested the tool and additional feedback was collected from the team and an advisory board. The final tool was presented to all Dutch care providers in transgender adolescent care. Results Care providers expressed a need for guidance in defining and assessing decision-making competence. Main moral challenges concerned discussing fertility options with young clients, dealing with co-occurring mental health difficulties and the decision-making role of parents. The final tool, named the Competence Consultant, is an interactive pdf containing four parts: (1) Clarify information; (2) Identify doubts and moral questions; (3) Guidance for conversations and (4) Overview and Conclusions. Discussion Developing an ethics support tool in a controversial care setting is highly relevant as it aims to help individual care providers in defining, discussing and dealing with their moral challenges in actual practice. The ‘Competence Consultant’ for transgender care providers contributes to their moral sensitivity and moral competence. It is an example of the development of innovative and integrative forms of thematic ethics support. (shrink)

There is a long philosophical tradition of addressing questions in philosophy of science and epistemology by means of the tools of Bayesian probability theory (see Earman (1992) and Howson and Urbach (1993)). In the late '70s, an axiomatic approach to conditional independence was developed within a Bayesian framework. This approach in conjunction with developments in graph theory are the two pillars of the theory of Bayesian Networks, which is a theory of probabilistic reasoning in artificial intelligence. The (...) theory has been very successful over the last two decades and has found a wide array of applications ranging from medical diagnosis to safety systems for hazardous industries. Aside from some excellent work in the theory of causation (see Pearl (2000) and Spirtes et al. (2001)), philosophers have been sadly absent in reaping the fruits from these new developments in artificial intelligence. This is unfortunate, since there are some long-standing questions in philosophy of science and epistemology in which the route to progress has been blocked by a type of complexity that is precisely the type of complexity that Bayesian Networks are designed to deal with: questions in which there are multiple variables in play and the conditional independences between these variables can be clearly identified. Integrating Bayesian Networks into philosophical research leads to theoretical advances on long-standing questions in philosophy and has a potential for practical applications. (shrink)

The book deals with the changing nature and with the history of the concept of scientific determinism from the classical mechanics until the time immediately preceding quantum mechanics: such a historical-philosophical reconstruction is aimed at (1) signalizing and overcoming the deficiencies of the received opinion on the topic and (2) understanding better a concept which has influenced science from the beginning. -/- Before dealing with historical matters I develop in the first Chapter a kind of new, three-dimensional (...) “measurement system” for analyzing any concept of scientific determinism: many different concepts have been developed in the course of history, and we need a classification system which, on the one hand, is inclusive and broad enough to deal with different concepts; on the other hand, which makes possible to differentiate with some precision between them. My “measurement system” has three dimension or parameter: the “strength” (of the determining link between different states of the physical system), the “depth” (depending on how strong the ontological commitment of the particular concept of scientific determinism is), and the breadth (referring to the domain or the object, to which a deterministic evolution is ascribed). -/- In the second chapter I discuss briefly some main shortcomings of the received opinion about scientific determinism. Then I try to identify the “core” of scientific determinism at its origins while at the same time embedding it in the broader historical-cultural context especially of the Renaissance. On the one hand I show how the core of scientific determinism was mathematical, and this distinguished it from other related concepts, as mechanism, the principle of sufficient reason, and the aristotelic conception of science. On the other hand, precisely the support which these related concepts provided to scientific determinism, together with its mathematical nature, endowed it with an incredible resistance against empirical classification. -/- In the following three chapters I analyze the historic-philosophical development of scientific determinism along the three parameter of my measurement system. -/- In the third Chapter I reconstruct the weakening of scientific determinism with respect to its depth: the starting point is the question about the extent in which the deterministic mathematical descriptions do refer. In the development of mechanics into analytical mechanics the more and more formal character of its mathematical descriptions became evident and it became less obvious that these formal, deterministic structures also have an immediate material truth. Parallel developments within epistemology, starting with Kantian philosophy (which I deal with quite in detail), let the deterministic structures (principle, laws, equations, causal relations) appear less absolute and real and more as a product of reason, as conventions, or as models. A brief consideration of the interpretation of mechanics and its principles by Jacobi, Hertz, Mach and Poincaré shows the implications of these developments. -/- The fourth chapter reconstructs the weakening of scientific determinism with respect to the strength of the determining link: here my work deepens the track which has been opened by Ian Hacking, who interpreted the so-called “probabilistic revolution” in the 19th Century as the main reason for the erosion of determinism. The increasing pervasiveness of statistical methods in the social and natural sciences in the course of the 19th Century gave rise to a conception of scientific laws which could dispense with strict determinism. A new, empirical interpretation of probability (Frequentism) and the statistical explanation of thermodynamic phenomena in physics even suggested chance phenomena to be a necessary condition for the emergence of natural laws. -/- The last part of my work (Ch. 5, 6 and 7) considers the period (2nd half of the 19th century until ca. 1920) in which the concept of scientific determinism became explicit and was discussed as a world-picture or a world-view – that is, in its maximal breadth. I argue that there were two main reasons for the emergence of an explicit and ideological opposition “determinism vs. indeterminism” at that time: the first was the successful application of the deterministic paradigm to sociology, history, physiology and psychology in the course of the 19th Century, which provided scientific determinism with ethical implications (in particular with respect to the problem of free will, which scientific determinism seemed to deny). The second, related reason is that in the 19th Century natural scientists became public men, science was increasingly popularized and scientific issues were increasingly related to life-issues, to worldview-questions, and even to politics. In Chapter 6 I reconstruct the debates on the issue “determinism vs. indeterminism” in such a public, ideological and sometimes even political context. Among the discussants were Fechner, Du Bois-Reymond, Helmholtz, Bernard, Ostwald, Haeckel, Boussinesq, Maxwell, Boutroux, Poincaré, Renouvier, James und Peirce. Also in Vienna the debate on the issue of determinism was fervid and took ideological and political connotations: Michael Stöltzner and Deborah Coen have pointed to a particular tradition of “Vienna Indeterminism” (Stöltzner), or Viennese liberal probabilism (Coen), which was characterized by a strongly empirical conception of science and by the full acceptance and appreciation of statistical thinking in science. In the last Chapter of my work I focus on the early philosophy of Edgar Zilsel, a philosopher who stood near to the Vienna Circle and who has been much neglected in the literature by now, and I suggest considering it as part of the “Vienna Indeterminism”. First, I show how he gave an indeterministic foundation both to statistical and causal knowledge as well as to irreversibility in physics. Second, I inquire into his philosophy of probability and show how it developed in parallel to the ones of Hans Reichenbach and Richard von Mises. Finally, Zilsel happens to be a further, relevant case-study for pointing to the ideological and political side of the issue of determinism. -/- At the end of this reconstruction it should have become clear how no physical theory, no empirical evidence and no experimental confirmation can support or contradict scientific determinism in its non-trivial formulations. The validity of any such formulation depends strongly not only (from the systematical point of view) from the definition of other concepts (like time, physical state, causality etc.), but also from the particular conception of science which more or less implicitly constitutes its background, and which is subjected to historical change. -/- (ISBN: 9783495491034).

The increasing application of network models to interpret biological systems raises a number of important methodological and epistemological questions. What novel insights can network analysis provide in biology? Are network approaches an extension of or in conflict with mechanistic research strategies? When and how can network and mechanistic approaches interact in productive ways? In this paper we address these questions by focusing on how biological networks are represented and analyzed in a diverse class of case studies. Our examples (...) span from the investigation of organizational properties of biological networks using tools from graph theory to the application of dynamical systems theory to understand the behavior of complex biological systems. We show how network approaches support and extend traditional mechanistic strategies but also offer novel strategies for dealing with biological complexity. (shrink)

Various errors can affect scientific code and detecting them is a central concern within computational science. Could formal verification methods, which are now available tools, be widely adopted to guarantee the general reliability of scientific code? After discussing their benefits and drawbacks, we claim that, absent significant changes as regards features like their user-friendliness and versatility, these methods are unlikely to be adopted throughout computational science, beyond certain specific contexts for which they are well-suited. This issue exemplifies the (...) epistemological heterogeneity of computational science: profoundly different practices can be appropriate to meet the reliability challenge that rises for scientific code.

Abstract.Formal topologies are today an established topic in the development of constructive mathematics. One of the main tools in formal topology is inductive generation since it allows to introduce inductive methods in topology. The problem of inductively generating formal topologies with a cover relation and a unary positivity predicate has been solved in [CSSV]. However, to deal both with open and closed subsets, a binary positivity predicate has to be considered. In this paper (...) we will show how to adapt to this framework the method used to generate inductively formal topologies with a unary positivity predicate; the main problem that one has to face in such a new setting is that, as a consequence of the lack of a complete formalization, both the cover relation and the positivity predicate can have proper axioms.

The article deals with an approach to the analysis of propositional attitudes based on the type-theoretical semantics proposed by A. Ranta and originating from the type theory of P. Martin-Löf. Type-theoretical semantics contains the notion of context and tools of extracting information from it in an explicit form. This allows us to correctly formalize the dependence on contexts typical of propositional attitudes. In the article the context is presented as a dependent sum type (Record type in the proof (...) assistant Coq). Ranta’s approach is refined and applied to the analysis of Quine’s phrase “Ralph believes that someone is a spy”. Three variants of formalization for this phrase are described which differ in the content of contextual knowledge and the way the truth values of the phrase are derived. Contexts are connected through the function of conversion, making it possible to relate truth values. As a result, it is shown that the instruments for working with contexts provided by type-theoretical semantics allow us to avoid the problem of opacity described by Quine. Provided formalization along with proofs is coded in Coq and made freely available. (shrink)

This book develops an intellectual framework for analyzing ethical dilemmas that is both grounded in theory and versatile enough to deal rigorously with real-world issues. It sees ethics as a necessary foundation for the social infrastructure that makes modern life possible, much as engineering is a foundation for physical infrastructure. It is not wedded to any particular ethical philosophy but draws from several traditions to construct a unified and principled approach to ethical reasoning. Rather than follow the common (...) academic practice of seeking a reflective equilibrium of moral intuitions and principles, it builds on a few bedrock principles of rational thought that serve as criteria for valid argumentation. It develops the ideas from the ground up, without presupposing any background in ethics or philosophy. Epistemologically, the book views ethics as parallel to mathematics, in that it relies on generally accepted proof techniques to establish results. Whereas mathematics rests on such proof paradigms as mathematical induction and proof by contradiction, ethics can be seen as relying on proof by applying consistency tests, such as generalizability and respect for autonomy. Utilitarianism also plays a key role, but it is reconceived as a deontological criterion. This approach obviously requires that these criteria be formulated more rigorously than is normally the case. To accomplish this, the book begins with the classical idea that an action is distinguishable from mere behavior by virtue of its having a coherent rationale, where coherence requires passing certain consistency tests such as generalizability. An action is therefore inseparable from its rationale, and generalizability is defined in terms of consistency with the rationale. A utilitarian criterion receives a similar treatment with respect to a means-end rationale. Respect for autonomy is grounded in a carefully developed action theory that takes into account such concepts as joint autonomy, implied consent, and the permissibility of interference with unethical behavior. It provides an account of responsibility that is both practical and theoretically satisfying, and it yields a novel solution of the much-discussed trolley car dilemmas. The book is written for a general audience and strives to be as readable and engaging as possible, while maintaining rigor. It begins by dispelling a raft of misconceptions that trivialize ethics and block its development as an essential tool of modern life, such as the notion that ethics is just a matter of opinion without rational foundation. After presenting the ethical principles just described, along with many examples, it provides several chapters that analyze real-life dilemmas, many obtained from the author's students and professional workshop participants. One cannot understand physics or chemistry without seeing how their principles are applied to real problems, and the same is true of ethics. These chapters demonstrate that a unified normative theory can deal with a wide range of real cases while achieving a reasonable level of objectivity and rigor. (shrink)

Solipsism indicates an epistemological position that denies the existence of ‘others’ by asserting that the ‘self’ is the only thing that can be known to exist. For sophist philosophers, the belief that “we can not know anything, and even if we do so, we cannot communicate it” is central to this theory. However, until now there has been little academic scholarship that has tried to provide answers to the pressing issues raised by solipsism. In Solipsist Ontology: Physical Things and (...) Personal Perceptual Space, Ural aims to redefine solipsism by analyzing and elaborating on traditional philosophical problems, such as empiricism and rationalism, as well as discussing problems of language, communication, and meaning. Ural reveals where solipsism has been previously ignored, pseudo-problems have arisen that disguise the sources of the problems with prejudices that concern the philosophical problems in question. Notably, many current, as well as traditional problems of ontology, epistemology, and language are bound up in discourses of solipsism. Ural argues that discarding solipsism as a philosophical discourse hinders new interpretations of traditional philosophical thought. This book offers a fresh perspective to solipsism by defining it in relation to concepts such as ‘physical things,’ ‘personal perceptual space’ and ‘identity.’ Importantly, Ural proposes that an understanding of ‘identity’ is not necessary in order to redefine solipsism. By building a logical system that fashions communication and solipsism as interrelated, it is possible to reject ‘identity’ as a useless concept and thus overcome the classic solipsist dilemma of “we are not able to communicate.” This original piece of research is an important and timely contribution to the field of philosophy that will be of great interest to teachers, researchers, and students.

It is a platitude in epistemology to say that knowledge excludes luck. Indeed, if one can show that an epistemological theory allows ‘lucky’ knowledge, then that usually suffices to warrant one in straightforwardly rejecting the view. Even despite the prevalence of this intuition, however, very few commentators have explored what it means to say that knowledge is incompatible with luck. In particular, no commentator, so far as I am aware, has offered an account of what luck is (...) and on this basis identified what it means for a true belief to be non-lucky. It is just such a view that I propose, however, and I hope to give a flavour of what this strategy involves here. In particular, I have two goals in this paper. The first is to outline the general contours of the position and show how such a view can account for the attraction of adducing a safety condition on knowledge, with all the epistemic benefits that this principle holds. Relatedly, I will also explain how an anti-luck epistemology can assist us in determining the best formulation of this principle. The second goal of the paper is to show anti-luck epistemology in action by highlighting how such a view can deal with the various problems posed by lottery-style examples. (shrink)

As Vincent Hendricks remarks early on in this book, the formal and mainstream traditions of epistemic theorising have mostly evolved independently of each other. This initial impression is confirmed by a comparison of the main problems and methods practitioners in each tradition are concerned with. Mainstream epistemol- ogy engages in a dialectical game of proposing and challenging definitions of knowledge. Formal epistemologists proceed differently, as they design a wide variety of axiomatic and model-theoretic methods whose consequences (...) they investigate independently of the need of giving counterexample-free definitions of knowledge. Or at least, this is a common way to explain where both disciplines stand in the larger landscape of epistemic theorising, and why interactions between them remain scarce. The main ambition of this book is to show that the distinction between formal and mainstream approaches should not preclude a fruitful interaction, and that it only takes the right outlook on their respective practices to disclose plenty of room for interaction.

Epistemic logic begins with the recognition that our everyday talk about knowing and believing has some systematic features that we can track and re‡ect upon. Epistemic logicians have studied and extended these glints of systematic structure in fascinating and important ways since the early 1960s. However, for one reason or another, mainstream epistemologists have shown little interest. It is striking to contrast the marginal role of epistemic logic in contemporary epistemology with the centrality of modal logic for (...) metaphysicians. This article is intended to help in correcting this oversight by presenting some important developments in epistemic logic and suggesting ways to understand their applicability to traditional epistemological problems. Obviously, by itself, tweaking the formal apparatus of epistemic logic does not solve traditional epistemological problems. Epistemic logic can help us to navigate through problems in a systematic fashion by unpacking the logic of the problematic concepts, it can also lead us to recognize problems that we had not anticipated. This is basically analogous to the role that modal logic has played in contemporary metaphysics. (shrink)

While appeals both to nature and to sceptical tendencies are widely acknowledged as determining factors in Hume's thought, there is considerable divergence of opinion regarding the degree of importance that Hume attaches to each notion. In an attempt to resolve this traditional controversy, this dissertation explores the meaning of Hume's philosophy as a whole in the light of its naturalistic and sceptical character. ;Instead of maintaining their opposition, the argument of the dissertation is that these two sides are complementary-- (...) class='Hi'>with nature both originating and, afterwards, mitigating the scepticism and scepticism in its turn both reinforcing and subsequently mitigating the naturalism in Hume's thinking. Their symbiotic relationship thus appears as the unifying element of the Humean philosophy. ;The first chapter addresses the problem of the unity of the three parts of Hume's A Treatise of Human Nature. Hume's references to nature and scepticism in his treatment of epistemological and moral problems are singled out and discriminated. ;The second chapter is devised as an interval in which the scholarly response to the problem of a unity to Hume's philosophy is examined in detail. What is typical of that response is a tendency to locate the unity in the scepticism or the naturalism of Hume's epistemological or moral conclusions. As a result of the examination of the views of leading scholars of Hume's thought, our findings can be set against a horizon within which his philosophy is traditionally interpreted. Focus then turns to the meaning and significance of scepticism and naturalism for ethics and epistemology in Hume's mature philosophy. The third chapter is devoted to An Enquiry Concerning Human Understanding, and the fourth to An Enquiry Concerning the Principles of Morals. In these chapters the dissertation's definitive view of Hume's solution to the philosophical problems of knowledge and morality is shaped. The thesis is advanced and defended that a dynamic relation obtains between Hume's notion of nature and his scepticism. Finally, in the conclusion this view is weighed against the preliminary findings of the Treatise and contrasted with the leading traditions of scholarly interpretation of Hume's philosophy as a whole.

Models are of central importance in many scientific contexts. The centrality of models such as the billiard ball model of a gas, the Bohr model of the atom, the MIT bag model of the nucleon, the Gaussian-chain model of a polymer, the Lorenz model of the atmosphere, the Lotka-Volterra model of predator-prey interaction, the double helix model of DNA, agent-based and evolutionary models in the social sciences, or general equilibrium models of markets in their respective domains are cases in point. (...) Scientists spend a great deal of time building, testing, comparing and revising models, and much journal space is dedicated to introducing, applying and interpreting these valuable tools. In short, models are one of the principal instruments of modern science. -/- Philosophers are acknowledging the importance of models with increasing attention and are probing the assorted roles that models play in scientific practice. The result has been an incredible proliferation of model-types in the philosophical literature. Probing models, phenomenological models, computational models, developmental models, explanatory models, impoverished models, testing models, idealized models, theoretical models, scale models, heuristic models, caricature models, didactic models, fantasy models, toy models, imaginary models, mathematical models, substitute models, iconic models, formal models, analogue models and instrumental models are but some of the notions that are used to categorize models. While at first glance this abundance is overwhelming, it can quickly be brought under control by recognizing that these notions pertain to different problems that arise in connection with models. For example, models raise questions in semantics (what is the representational function that models perform?), ontology (what kind of things are models?), epistemology (how do we learn with models?), and, of course, in philosophy of science (how do models relate to theory?; what are the implications of a model based approach to science for the debates over scientific realism, reductionism, explanation and laws of nature?).

My new book is HERE for download: https://www.academia.edu/31495642/_Meta-Philosophy_Meta-Cognition_and_Critique_of_Doing_Philosophizi ng Abstract So far in my books and articles I have dealt with the following‭ (‬I hope I do not commit self-plagiarism by referring to my previous work and ideas expressed therein‭! ‬Lol‭)‬: -/- My (...) own discussions or‭ ‘‬philosophizing‭’ ‬follow right at the end after the numerous and very lengthy quotes from philosophers.‭ ‬The nature of the subject-matter of philosophy,‭ ‬the methodology,‭ ‬methods,‭ ‬techniques and tools of doing philosophy or philosophizing,‭ ‬the nature of the different steps or stages of the process/es of theorizing,‭ ‬the fact that doing philosophy are some of the stages of theorizing,‭ ‬the fact that philosophers lack meta-cognition and/or meta-reflection of these things.‭ ‬If they had awareness of what and how they are doing philosophy they might not become involved in quibbling over concepts and the differentiations of these concepts.‭ ‬It is as if philosophers are blind to what they are doing and have been doing for thousands of years,‭ ‬with the result that they continue repeating the same thing‭ – ‬arguing with words over the use of words and in the process creating more and more‭ –‬isms.‭ ‬They are seemingly unable to escape from such‭ –‬isms and their implications.‭ ‬Instead of getting or going anywhere they way they conceive‭ (‬of‭) ‬problems and express their questions they end up with conceiving of notions that cannot be solved or dissolved.‭ ‬They enclose themselves in an insular world or bubble of their own making,‭ ‬compared to sciences investigating humans and the different features and systems of the human body who find irrelevant the problems that philosophers have with things such as the brain,‭ ‬cognition,‭ ‬mind,‭ ‬consciousness,‭ ‬perception,‭ ‬thinking,‭ ‬etc.‭ ‬Sciences deal with these things on many levels and multi-dimensional while philosophers try to restrict them to a single level in one dimension by their words and the way they use those words.‭ ‬Consequently they lose sight of their objects and are unable to question them or express questions about them in a meaningful manner. -/- In my articles and books on the subject-matter I dealt with the traditional branches of philosophy and that with the differentiation of other disciplines and discourses the discourse of philosophy lost subject-matter.‭ ‬I mentioned newer areas of‭ ‘‬philosophy‭’‬,‭ ‬such as X-Phi,‭ ‬Philosophy’s interdisciplinary involvement in for example cognitive sciences,‭ ‬that there exists a philosophy of every discipline possible‭ (‬eg philosophy of science,‭ ‬art,‭ ‬music,‭ ‬sport,‭ ‬social sciences,‭ ‬etc‭)‬,‭ ‬that discourses such as Logic,‭ ‬Critical Thinking,‭ ‬Argumentation and argument maps,‭ ‬Reasoning,‭ ‬etc are relevant to and employed by many if not all disciplines and many discourses and are not uniquely subject-matter of the discourse of philosophy and does not have to form part of or be taught as subject-matter of philosophy. -/- I identified and discussed the methodology,‭ ‬methods,‭ ‬techniques and tools of doing philosophy and some underlying or implicit transcendentals such as pre-suppositions,‭ ‬suppositions and assumptions.‭ ‬I explore the nature of the different features,‭ ‬aspects,‭ ‬characteristics,‭ ‬steps and stages of the processes of theorizing.‭ ‬I showed that doing philosophy or philosophizing employ and/or consist of some of these features,‭ ‬steps and stages of theorizing. -/- As I involuntary have‭ (‬am‭)‬,‭ ‬seemingly endless‭ (‬a stream of consciousness like‭) ‬philosophically-‭ (‬question or problem and insight‭) ‬related‭ ‘‬intuitions‭’‬,‭ ‬it is difficult,‭ ‬painful and frustrating to me for that to be interrupted by social interaction,‭ ‬talking to people,‭ ‬phones,‭ ‬executing all sorts of‭ ‬mundane activities,‭ ‬etc.‭ ‬To understand or cope with this‭ ‘‬mental state‭’ ‬is one of the reasons why I need to explore meta-cognition or thinking about thinking,‭ ‬especially one’s own thinking and related‭ ‘‬activities‭’‬.

An introductory text which deals with several of the basic problems of semantical and logical analysis. Most of the discussion is devoted to problems of usage, rules, inference, and validity. A rather cumbersome symbolism results from the author's explicit attempt to treat these problems with the formal tools of elementary symbolic logic.--D. P. B.

The Anthropocene overthrows classical dichotomies like technology and nature and a new class of beings emerges: hybrids. The transitive status of hybrids - which establishes an extra, separate, 'third' ontological category, going beyond the dichotomy between nature and technology - constitutes a significant problem for environmental philosophy and philosophy of technology since they traditionally focus on either 'nature' (natural entities) or 'artefacts' (technological objects). In order to reflect on the ethical significance of hybrids, a classification of different types of hybrids (...) is required. Such a classification is provided by this article, based on insights from both environmental philosophy and philosophy of technology. After explaining why a new class of beings emerges in the Anthropocene, and reflecting on the one-sidedness of philosophy of technology and environmental philosophy in their focus on either technology or nature, we propose a new classification of hybrids in this article that provides a new starting point for reflections on the moral significance of hybrids in environmental philosophy and philosophy of technology.

The question of bias in methodology and terminology is a problem that faces researchers east, west, north and south; however, it faces Third World intellectuals with special keenness. For although they write in a cultural environment that has its own specific conceptual and cultural paradigms, they nevertheless encounter a foreign paradigm which attempts to impose itself upon their society and upon their very imagination and thoughts. When the term “developmental psychology” for instance is used in the West Arab scholars (...) also say “developmental psychology”, when “applied psychology” is mentioned they hurry to use the same term etc. Why not establish a new science with its own mechanisms, methodologies and points of reference to deal with epistemological biases and open up the gate of ijtihad with respect to them? This collection of papers aims to discover some of the biases latent in our terminology, methodologies, research tools, and conceptual principles, and to propose alternative ones marked by a greater degree of independence and neutrality. This is not to belittle the human value of the West’s creative contributions but to emphasize the danger of making it the ultimate point of reference and then trying to continuously play “catch up” with it.

As current events around the world have illustrated, epistemological issues are at the center of our political lives. It has become increasingly difficult to discern legitimate sources of evidence, misinformation spreads faster than ever, and the role of truth in politics has allegedly decayed in recent years. It is therefore no coincidence that political discourse is currently saturated with epistemic notions like ‘post-truth,’ ‘fake news,’ ‘truth decay,’ ‘echo chambers,’ and ‘alternative facts.’ This book brings together leading philosophers to (...) explore ways in which the analytic and conceptual tools of epistemology bear on political philosophy, and vice versa. It is organized around three broad themes: truth and knowledge in politics; epistemic problems for democracy; and disagreement and polarization. The authors provide new and rich insights on topics such as: propaganda, fake news, weaponized skepticism, belief polarization, political disagreement, the epistemic value of democracy, voter ignorance, irrationality in politics, political bullshit, and identity politics.

Dealing with situations where parents’ views about treatment for their child are strongly opposed to doctors’ views is one major area of ethical challenge in paediatric health care. The traditional approach focuses on the child’s best interests, but this is problematic for a number of reasons. The Harm Principle test is regarded by many ethicists as more appropriate than the best interests test. Despite this, use of the best interests test for intervening in parental decisions is still very (...) common in clinical settings and can lead to confusion. In this paper, I propose the Zone of Parental Discretion as a means of putting into practice the key ideas of the Harm Principle, in a clear, step-by-step process. The Zone of Parental Discretion provides a tool for ethical deliberation by clinicians and ethicists about all situations in which parents and doctors disagree about treatment of a child, whether parents are refusing medically recommended treatment, or requesting non-recommended treatment.

Many problems of inequality in developing countries resist treatment by formal egalitarian policies. To deal with these problems, we must shift from a distributive to a relational conception of equality, founded on opposition to social hierarchy. Yet the production of many goods requires the coordination of wills by means of commands. In these cases, egalitarians must seek to tame rather than abolish hierarchy. I argue that bureaucracy offers important constraints on command hierarchies that help promote (...) the equality of workers in bureaucratic organizations. Bureaucracy thus constitutes a vital if limited egalitarian tool applicable to developing and developed countries alike. (shrink)

The purpose of this paper is to present a formal model of social net- works suitable for studying questions in social epistemology. We show how to use this model, in conjunction with a computer program for simulating groups of inquirers, to draw conclusions about the epistemological prop- erties of different social practices. This furnishes us with the beginnings of a systematic research program in social epistemology, from which to approach problems pertaining to epistemic (...) value, optimal organization, and the dynamics of multi-agent inquiry.

It is astonishing that we humans are able to have, act on and express moral beliefs. This dissertation aims to provide a better philosophical understanding of why and how this is possible especially when we assume metaethical expressivism. Metaethical expressivism is the combination of expressivism and noncognitivism. Expressivism is the view that the meaning of a sentence is explained by the mental state it is conventionally used to express. Noncognitivism is the view that the mental state expressed by a moral (...) sentence is a noncognitive, desire-like state. The central question of this dissertation is this: "How can metaethical expressivists explain that we are able to express moral beliefs?" The shortest answer this dissertation will give is the following: "by becoming `dispositional expressivists´." Dispositional expressivists hold that moral beliefs are dispositions to be in certain mental states that resemble desires. More precisely, a central thesis of this study is that to hold a moral belief is to be disposed to be in a desire-like, noncognitive state where this state has some specific structure. This dissertation arrives at and justifies this thesis by making a number of steps. It starts with preparing the ground by developing a general theory of what it is for a sentence to express a mental state. Roughly, this theory states that for a sentence to express a mental state is for that sentence to be conventionally used to perform a speech act which counts as sincere only if the user or speaker is in that mental state. This theory of expressing satisfies all the constraints that must be satisfied for it to be compatible with the purposes of metaethical expressivism. The next step is to provide a solution to the most notorious semantic problem confronting metaethical expressivism, the problem of explaining how sentences containing moral words can have compositional meaning and stand in logical relations also known as the Frege-Geach or embedding problem. Building on the research of Mark Schroeder, a new expressivist semantics, called `Attitude Semantics´, will be developed for a first-order language. The motivating idea underlying attitude semantics is that expressivists can avoid the problematic feature of so-called `biforcation´ if they treat the structures of the mental states expressed by moral sentences as well as that expressed by non-moral sentences as being isomorphic. In order to give those structures a philosophically interesting interpretation, it will be suggested that we treat sentences as expressing dispositional states. As a toy example we will treat the sentence `murder is wrong´ as expressing the disposition to be for blaming for murder. After dealing with the Frege-Geach problem, I turn to the metaethical expressivists' project of quasi-realism. Two major goals of this project are to explain how moral sentence can be truth-apt and how the states expressed by them can be regarded as moral beliefs. In order to establish those goals I critically examine a number of theories of truth-aptness by providing counterexamples to them. I then present my own theory which says that a sentence is truth-apt iff and because there is a conventional way to use it to express a belief. What is new about this theory is that it treats expressing a belief as being explanatorily more basic than being truth-apt. Belief, according to this theory, explains truth-aptness, not vice versa. This has the important consequence that it shows that what I call the `orthodox strategy´ of quasi-realists is mistaken and needs to be inverted: expressivists must `earn the right´ to moral belief before they can establish that moral sentences are truth-apt, and not the other way round. The second part of this dissertation is then concerned with the question of what it is to hold a moral belief and how they can figure in rational reasoning. In short: it is concerned with earning the right to moral belief. After discussing the major problems confronting a noncognitivist theory of belief, most importantly what I call the `tightrope problem´, I argue for a dispositional form of noncognitivism about moral belief that combines elements from Eric Schwitzgebel's dispositionalism about belief and Sebastian Köhler's `conceptual role expressivism´. This dispositional noncognitivism perfectly matches and justifies the dispositionalist interpretation of the expressivist semantics developed before. In order to fully earn the right to moral belief, however, metaethical expressivists must also deal with several epistemological objections concerning the rationality of moral belief. The first objection I deal with comes from Derek Baker and is directed against Mark Schroeder's specific development of expressivism. I deal with this objection because my own theory bears close resemblance to Schroeder's theory and so it might be worried that it confronts the same issues. Fortunately, we will see that Baker's objection rest on a number of mistaken assumptions and so neither applies to Schroeder's expressivism nor to the version which I defend in this study. The other epistemological objection to metaethical expressivism I deal with is Cian Dorr's famous wishful-thinking objection. In contrast to previous replies to this objection I attack it by directly questioning the central assumption on which it rests, namely that reasoners can never be justified in basing a factual belief on a desire-like state. I argue that this is false, and that under certain conditions reasoning from desire-like mental states to factual beliefs is justified. My argument shows that even if holding a moral belief is being in a desire-like noncognitive state, basing factual belief on a moral belief can give one an epistemic reason for the factual belief. Hence, even if moral thoughts are wishes, moral thinking is not wishful thinking. I take my arguments to earn the dispositional expressivist the right to moral belief. By the previously defended theory of truth-aptness in terms of belief, this allows the dispositional expressivists to conclude that moral sentences are also truth-apt. This finishes the quasi-realist project of this dissertation. In the last part of this dissertation I switch gears and present two unnoted problems for metaethical expressivists having to do with explaining moral motivation. Both arguments are surprisingly simple. The first one is this: if motivation requires a belief as well as a desire (Humeanism), and moral judgments motivate by themselves (internalism), then moral judgments cannot be desires only. If this argument is sound, it shows that the famous `motivation argument´ not only entails the falsity of cognitivism, but also the falsity of noncognitivism. The second argument is the following: moral judgments when combined with suitable external desires motivate to act (externalism), but if motivation requires belief as well as desire (Humeanism), then moral judgments cannot be desires only. I discuss several ways in which noncognitivists might want to deal with those problems, but leave it as an open question whether those solutions will ultimately be viable. Overall, this dissertation makes serious contributions to the research program of metaethical expressivism. It makes proposals for how to solve a number of notorious problems, such as the Frege-Geach problem in semantics and the wishful-thinking problem in epistemology. Besides this, however, it also raises two new problems for metaethical expressivism in the philosophy of action. For those reasons this dissertation will be of interest for anyone who wants to defend or criticize expressivism in metaethics, and more generally, anyone who wants to better understand our astonishing ability to express moral beliefs.

This book is an introduction to elementary logic (classical propositional and first-order logic), comprising brief summaries of the basics of elementary logic, with the emphasis on typical questions and procedure descriptions and with a large number of corresponding exercises and problems. Solutions are given for each problem and exercise, often with commentaries. The first part, Basics of Logic, deals with (a) formal language, models, Venn diagrams for sentences, and translation from natural into formal (...) language and vice versa, (b) deduction and refutation methods in the format of natural deduction (Fitch and Suppes-Lemmon styles), tableau system and Venn diagrams, and (c) basic logical properties and relations (consistency, validity, consequence, equivalence, various types of opposition, logical completeness and independency, relationship between syntax and semantics). The second part, Logic in Understanding and Analysis, introduces into (a) logical approach to problem solving in concrete situations and events as presented in brief tales and anecdotes, (b) discovering the meaning, and reconstruction of logical interconnections, in ordinary, scholarly and philosophical texts, (c) application of already mastered logical tools in examining and defining further theoretical (logical, scientific) concepts and in building formal languages. The shorter third part, From the Traditional Logic, is dedicated to the traditional logic of concepts, judgements and syllogisms, largely with the use of Venn diagrams. (shrink)

Can the humanities survive in an age of science? Yes, if analytic philosophers will only stop picking on traditional philosophy and recognize the latter's proper and legitimate role in society. That role according to Veatch, is one that enables man to grasp the nontechnical meaning of our everyday world where we learn to know and understand the nature of things. Such knowledge serves as the necessary ground for not only our common sense attitudes, but also for establishing values and (...) norms for a moral life. What is more, Veatch contends, this knowledge of man, his nature, and his values is not merely emotive or psychological; rather, it is factual. Using traditional logic as its organon, knowledge of a more humanistic variety can establish itself as factual in spite of analytical claims to the contrary. Thus Veatch proceeds from the general problem of the humanities versus science to the more specific area of the two logics: traditional Aristotelian logic and modern symbolic logic. The former is the proper tool of the humanities, the latter serves the method of the physical sciences. Both logics deal with facts in their respective areas. Traditional logic lays bare the facts that make human life meaningful, while symbolic logic operates with formal structures that make technological progression possible. One logic does not cancel out the other. Veatch prefers to view the two logics as a "both... and" structure rather than as an "either... or" situation. To effect this he launches a counterattack against analytic philosophy's repudiation of traditional logic. He charges certain analysts with committing a fallacy that makes necessities and impossibilities a mere function of our language rules. Veatch, however, sees our rules of language as determined by real necessities in the world. He claims that Wittgenstein's celebrated attack on the doctrine of essences never really denies Aristotle's notion of substance as the formal or intelligible aspect of individual entities. Although his justification of traditional logic as a grammar for discourse in the humanities presupposes certain metaphysical commitments, on the whole his plea for traditional philosophy is persuasive.--J.

True contradictions are taken increasingly seriously by philosophers and logicians. Yet, the belief that contradictions are always false remains deeply intuitive. This paper confronts this belief head-on by explaining in detail how one specific contradiction is true. The contradiction in question derives from Priest's reworking of Berkeley's argument for idealism. However, technical aspects of the explanation offered here differ considerably from Priest's derivation. The explanation uses novel formal and epistemological tools to guide the reader through a valid (...) argument with, not just true, but eminently acceptable premises, to an admittedly unusual conclusion: a true contradiction. The novel formal and epistemological tools concern points of view and changes in points of view. The result is an understanding of why the contradiction is true. (shrink)

Doxastic TheoriesThe application of formal tools to questions related to epistemology is of course not at all new. However, there has been a surge of interest in the field now known as “formal epistemology” over the past decade, with two annual conference series and an annual summer school at Carnegie Mellon University, in addition to many one-off events devoted to the field. A glance at the programs of these series illustrates the wide-ranging set of (...) topics that have been grouped under this name, ranging from rational choice theory and the foundations of statistics, to logics of knowledge and formal measures of coherence, with much more besides.In this paper I will ignore most of these topics, and just trace some parts of the history of two ideas about belief whose current interaction may lead to future progress. One idea is the idea of belief, disbelief, and suspension of judgment as a meaningful tripartite dis .. (shrink)

Within post - Kuhnian, philosophy of science, much effort has been devoted to issues related to conceptual change, such as incommensurability, scientific progress and realism, but mostly in terms of reference, without a fine - grained theory of scientific concepts/senses. Within the philosophy of language and of mind tradition, there is a large body of work on concepts, but the application to scientific concepts has been very tentative. The aim of this paper is to propose a general framework for a (...) theory for the individuation of scientific concepts. The general view about the individuation of concepts favored here is the possession - condition approach: to individuate a concept is to identify its possession conditions. The general metascientific tools for the analysis of scientific theories are model - theoretic, more specifically, structuralist: scientific theories, the entities to which scientifc concepts belong, are model - theoretic theory - nets. The general idea about the content of scientific concepts that inspires this proposal comes from: (i) our grandfathers’ "laws - plus - correspondence rules", (ii) Kuhns "laws applied to exemplars" views and (iii) moderate operationalism. The aim is to show that some clarification can be gained applying the possesion condition appproach to (an expansion of) these three elements using structuralist metascientific tools. First, I briefly present the two main structuralist ideas I shall use: the difference between observability and non - theoreticity, and the notion of theory - net. Second, I informally introduce the five components that come from my reading of the three traditional elements; these components are, or are not, plausible independently of how they will be integrated within a theory of concept - identity. Third, I present the kore of the theory of possession conditions for concept - identity that we shall use for the integration of such components. Finally, I propose the general traits of the possession condition that corresponds to each of these five components, I present some problems and point out some possible ways of dealing with them.

The extensive literature on the Learning Organisation proposes that a competitive advantage can be achieved through the systematised generation and application of knowledge. Consequently, much of the debate concerns the processes, routines and organisational features that a firm should adopt to learn more, and faster, than its competitors. Less attention is given to understanding the nature of the knowledge that is created by these Learning Organisations. We hold that the topic is more important than its current weight in the literature (...) because the performance claims of the models proposed critically depend upon the newly acquired knowledge replacing ignorance or knowledge with less utility. In this paper we explore the nature of knowledge that Learning Organisation theory seeks to create by articulating implicit epistemological assumptions found within the literature. We show that the capacities of each epistemology to help an organisation reject falsehood and make greater use of its knowledge are critically undermined by these very routines. The paper concludes by highlighting the importance of a sceptical epistemology and outlines a process that would strengthen doubting behaviour. (shrink)

This paper examines naturalized epistemology's prospects for dealing with Cartesian skepticism and the traditional problem of induction. It is argued that Quine's approach fails to satisfy the skeptic who does not already embrace some version of scientific method. In addition, it is argued that Goldman's reliabilism enables one to address these issues empirically only if one rejects the view that if we are capable of confirming an empirical hypothesis, we are also capable of disconfirming it. The article (...) ends with a negative appraisal of the role relevant alternatives play in Goldman's account, particularly with regard to second order knowledge. (shrink)

The traditional problem of other minds is epistemological. What justification can be given for thinking that the world is populated with other minds? More recently, some philosophers have argued for a second problem of other minds that is conceptual. How can we conceive of the point of view of another mind in relation to our own? This article retraces the logic of the epistemological and conceptual problems, and it argues for a third problem of other (...) minds. This is the phenomenological problem which concerns the philosophical question of experience. How is another mind experienced as another mind? The article offers dialectical and motivational justification for regarding these as three distinct problems. First, it argues that while the phenomenological problem cannot be reduced to the other problems, it is logically presupposed by them. Second, the article examines how the three problems are motivated by everyday experiences in three distinct ways. (shrink)

Conversation is one of the main contexts in which we are conducting inquiries. Yet, little attention has been paid so far in pragmatics or epistemology to the process of inquiry in conversation. In this paper, we propose to trigger such an investigation through the development of a formal modelling based on inquisitive pragmatics—a framework offering a semantic representation of questions and answers, along with an analysis of the pragmatic principles that govern questioning and answering moves in conversations (...) geared towards information exchange. Our starting observation is that an interrogative inquiry in a conversation takes the form of a finite sequence of questioning and answering steps, and appears thereby as an inherently temporal process. The central notion of interrogative protocol introduced in this paper precisely aims to capture the temporal dimension of inquiry. Interrogative protocols are defined as branching-time tree structures encoding all the possible sequences of questioning and answering steps—i.e., all the possible inquiry paths—that can subsequently occur in a starting conversational situation in accordance with the principles of inquisitive pragmatics. They provide us with a formal environment to define and investigate the epistemological notions of interrogative inquiry and interrogative consequence in conversational contexts. One of the main interests of the resulting framework is to enable a formal investigation of central epistemological issues relative to interrogative inquiry under the form of computational problems. We frame three key inquiry problems along this line, and we then propose an algorithmic procedure for solving them in the restricted case where the inquirer has at her disposal a finite number of questions in her inquiry. We conclude by relating our approach to Wiśniewski’s Erotetic Search Scenarios and Hintikka’s Interrogative Model of Inquiry. (shrink)

The paper argues, that a direct formalization of the way common sense thinks about the numerical identity of enduring entities, requires that traditional predicate logic is developed. If everyday language mirrors the world, then persons, organisms, organs, cells, and ordinary material things can lose some parts but nonetheless remain numerically exactly the same entity. In order to formalize this view, two new logical operators are introduced; and they bring with them some non-standard syntax. One of the operators is (...) called ‘the instantiation operator’; it is needed because the existential quantifier and its traditional relatives cannot do the job required. The other operator is called ‘the form-on-matter operator’, and it allows an individual (an instance of a form) to stay the same even though some of its parts (its constituting matter) is taken away from it. Also, a certain kind of predicates, called ‘nature terms’, is needed in order to represent what gives a particular its kind of identity. Both the operators and the nature terms introduced can be used in constructions of formal languages and formal systems, but no such constructions are made in the paper. The paper is structured as a comment on the philosophical problem called ‘the problem of the cats Tibbles and Tib’. (shrink)

This book addresses two questions that are highly relevant for epistemology and for society: What is ignorance and how should we rationally deal with it? It proposes a new way of thinking about ignorance based on contemporary and historical philosophical theories. In the first part of the book, the author shows that epistemological definitions of ignorance are quite heterogeneous and often address different phenomena under the label "ignorance." She then develops an integrated conception of ignorance that (...) recognizes doxastic, attitudinal, and structural constituents of ignorance. Based on this new conception, she carves out suggestions for dealing with ignorance from the history of philosophy that have largely been overlooked: virtue-theoretic approaches based on Aristotle and Socrates, consequentialist approaches derived from James, and deontological approaches based on Locke, Clifford, and Kant. None of these approaches individually provide a satisfying approach to the task of rationally dealing with ignorance, and so the author develops an alternative maxim-based answer that extends Kant’s maxims of the sensus communis to the issue of ignorance. The last part of the book applies this maxim-based answer to different contexts in medicine and democracies. How Should We Rationally Deal with Ignorance? will appeal to scholars and advanced students working in epistemology, political philosophy, feminist philosophy, and the social sciences. (shrink)

In the traditional system of Chinese families, individuals are embedded in the institution of the family with defined obligations to enhance family development. As a consequence of the male-biased sex ratio at birth in China since the 1980s, an increasing number of surplus rural males have been affected by a marriage squeeze becoming involuntary bachelors. Under China’s universal heterosexual marriage tradition, family development of rural involuntary bachelors has largely been ignored, but in China’s gender-imbalanced society, it is necessary (...) to adopt a family-based approach to identify and study the plight of rural involuntary bachelors. Studies on gender imbalance indicate that these men face multiple risks from the perspectives of their life course, the family life cycle, and the family ethic. To a certain extent, these risks are caused by a conflict between the individual’s family life and family ethics and are mainly reflected in problems concerning marriage, health, and old-age support. Not only do these vulnerabilities affect the individual and family development across the whole life cycle but also pose major risks to social development in the face of strong gender imbalance. In order to deal with risks faced by rural involuntary bachelors, core ethical principles, including autonomy, beneficence, and justice, need to be adopted. Through adjustments to informal support provided by the family and formal support provided by policy-makers, risk of uncertainty in family development faced by rural involuntary bachelors could be reduced.

This paper analyses the paradigms of interpretation and the evolution of the creative processes in music and law. Whether it is matter of a score or a law, the text is reborn through the work of the interpreter who, in dealing with the epistemological problem of the understanding, has to harmonize the purity of the philological reconstruction of the object with the need to actualize its sense. Moving from the creative character of every interpretation—neither the musician can (...) be reduced to a mere executor of a concatenation of musical symbols on the staff as Stravinsky wanted nor the judge may be conceived as a bouche de la loi according to Montesquieu’s theory—this work, after having discussed Gadamer and Betti’s hermeneutical approaches to music and law, focuses on the issue of the limits to the interpreters’ freedom. The interpretation here proposed revolves around improvisation, seen as a typical cultural practice of the aesthetic dimension of music. Improvisation, which from baroque to jazz does not correspond to the realm of absolute freedom, is used as a trait d’union in order to make a comparison with legal experience. This is particularly true with the development of case law, which becomes increasingly problematic especially in the light of “liquid modernity”, where the “polytheism of values” has been gaining strength. Seen from this perspective, the comparison between the judge and the musician in their activity as interpreters of a formalized system of signs highlights the controversial relationship between form and creativity, the accuracy of the text and the requisites deriving from the social context, certainty and justice.

The article deals with the philosophical problem of the objectivity of knowledge in relation to the ideas and postulates advanced by feminist critics from the 1960s on. To this end, I take the historical perspective into account and present successively selected threads of feminist criticism of the traditional theory of knowledge, followed by selected positive aspects of feminist epistemology. First of all, I discuss feminist criticism of the androcentric research model, which is based on the doctrine of (...) the disembodied, detached objectivity of the subject and object of research as well as of knowledge itself. Next, I present selected feminist approaches to knowledge which constitute cognitively valuable proposals for the transformation of the traditional theory of knowledge through the application in philosophical reflection and research of the feminist research perspective.

This paper concerns the recent debate on the nature and motivations of the epistemological project advanced in Rudolf Carnap's (1891-1970) Aufbau. Much of this debate has been initiated by Michael Friedman and Alan Richardson who argue (against the received view of the Aufbau as a foundationalist defense of empiricism) that Carnap's epistemological project is located in the tradition of neo-Kantian epistemology. On this revisionist reading of the Aufbau, Carnap's project is not motivated to address traditional empiricist (...) problems regarding the justification of knowledge, but rather to show how objective knowledge is possible. A central aspect of the Aufbau that is neglected in the revisionists' analysis is the role of epistemic justification in Carnap's project. The aim of the present study is to argue that although the general epistemology in the Aufbau can be cast as neo-Kantian, Carnap's method of construction theory (or rational reconstruction) is formulated precisely as an empiricist method for the justification of conceptual knowledge. Construction theory radically redefines `empirical justification' into a formal-conventional notion, and is part of Carnap's more general agenda of redefining epistemology as a purely formal discipline.

The paper discusses ten philosophical problems in deontic logic: how to formally represent norms, when a set of norms may be termed ‘coherent’, how to deal with normative conflicts, how contraryto-duty obligations can be appropriately modeled, how dyadic deontic operators may be redefined to relate to sets of norms instead of preference relations between possible worlds, how various concepts of permission can be accommodated, how meaning postulates and counts-as conditionals can be taken into account, and how sets (...) of norms may be revised and merged. The problems are discussed from the viewpoint of input/output logic as developed by van der Torre & Makinson. We argue that norms, not ideality, should take the central position in deontic semantics, and that a semantics that represents norms, as input/output logic does, provides helpful tools for analyzing, clarifying and solving the problems of deontic logic.

In lieu of an abstract, here is a brief excerpt of the content:The Past and Future of Environmental Ethics/PhilosophyBryan Norton (bio)About 15 years ago, at one of the first meetings of the group known as the International Society for Environmental Ethics (ISEE) at American Philosophical Association (APA) meetings, I drew an analogy with the field of medical ethics, arguing that environmental ethicists should look beyond philosophy departments and seek liaisons with Schools of Forestry, Schools of Marine Science, and (...) Environmental Studies Programs, and that philosophers should take a more active role in policy discussions and process. At that time, I was actively engaged in the actual policy processes, at the Environmental Protection Agency and other agencies, and perceived that: (a) These agencies desperately needed the kinds of conceptual and normative analysis philosophers could provide; but that (b) Practitioners of environmental policy did not find that the categories and concepts of traditional "metaphysical" approaches to environmental value provided them with useful guidance in policy decision making.My urging gained me some heavy criticism, and even made me some enemies, as leading members of the environmental ethics establishment openly complained that my judgment—in seeing philosophy of environmental protection as needing a basis in analysis of possible actions—had been compromised by "spending too much time inside the beltway."Since those early years, I have watched my colleagues in environmental ethics debate this point, but mainly as a sideline to their metaphysical speculation.In the meantime, my colleagues in medical ethics have populated medical schools, formed liaisons with medical research institutions, and become regular commentators on newscasts about ethically controversial medical issues. Meanwhile, Chris Stone, the legal scholar, had his students do a word search of the Congressional Record over several years, and found almost no references to "environmental ethics."As I see it, there are three differences between the environmental ethics and the medical ethics cases: (1) Philosophers have responded to medical issues by engaging practitioners, while most environmental ethicists have become, at best, "token" members of philosophy departments and, whereas medical ethics practitioners tend to talk about decision criteria [End Page 134] ("informed consent", etc.), environmental ethicist continue to concentrate on the metaphysical foundations of environmental values; (2) The medical profession, beset with public controversies, recognized the need for more ethical discourse about medical choices, and actively embraced philosophers in their programs, whereas most environmental practioners cannot see how philosophical analysis will help them to make better decisions; and (3) Being much wealthier than environmentalists, the medical schools and professionals were able to initiate positions and offer financial support, while environmental ethicists have to compete with other environmental researchers and commentators for small pots of funding.While we can't do much about (3), we can, I assert, do a lot more about (1) and (2). With respect to philosophy departments, the trend may be(and in my view should be) toward developing joint appointments between philosophy departments and policy schools, forestry schools, and environmental studies programs. This will bring philosophers and students into more direct contact with real problems and the language of decision making, rather than metaphysics. And with respect to point (2), I continue to urge environmental philosophers to address real problems, rather than operating on an abstract level and then finding "applications" of these abstractions.Philosophers, in other words, should become more "pragmatic" in their approach to both policy and philosophy. One aspect of this move is the need—after years of thinking of environmental philosophy as environmental ethics—to concentrate on epistemological, not metaphysical, aspects of environmental science and decision making.Let me expand on this last point, because it seems to me to be the most important consideration affecting the future of environmental ethics, at least in the short and medium run. I think the central debates about whether nonhumans have "intrinsic value" will be (and should be) replaced with a vigorous discussion of the epistemology of all environmental values. Recently, two leading environmental philosophers, Baird Callicott and Mark Sagoff, have strongly endorsed what would traditionally be called "non-naturalist" approaches to the epistemology of environmental ethics. For Sagoff, this involved positing "ethical and aesthetic" facts which should guide environmental policy discourse away from any discussion of the utilitarian benefits of an improved... (shrink)

The issues treated in this book derive a certain degree of unification from their relation to the general theme of the completeness of scientific theories. Unfortunately, when a philosopher addresses himself to the question of the completeness of an empirical theory, it is far from clear at the outset just what the problem is. Schlegel, to be sure, explicates three different notions of completeness which may be relevant here: the logical, physical, and pragmatic aspects. By the first, Schlegel means the (...) usual set of issues having to do with the deductive and semantic structure of formal theories, the second refers to "the problems that are to be answered in terms of what is discovered by science about the natural world," and the third refers to "the factors in the completeness of science that seem to be chiefly dependent on the interests of scientists." As these formulations suggest, the level of logical and philosophical rigor is hardly commensurate with the kind of investigation one would expect. An early chapter deals with an epistemology of physics in which a class of entities called "constructs" plays the central role. Unfortunately, it is never clear whether constructs denote objects, properties, facts, sentences, or something else. On the other hand, the materials in this chapter are largely irrelevant to the subsequent discussion. Schlegel does an admirable job of scientific exegesis on the present state of quantum physics and cosmology. With regard to the former, he is an advocate of the "Copenhagen view," and he argues that a sort of natural limit of description and explanation has been reached. As to cosmology, Schlegel looks forward to a narrowing of the range of alternate theories as more data become available. In the chapter on purely formal questions a number of oversights seem to have been committed. The exposition of Gödel's incompleteness theorem is inaccurate in that it is not shown that provability can be defined intra-systematically. Schlegel's discussion of how the theorem might apply to scientific theories is suggestive, but also confusing. The chapter on infinity treats the continuum hypothesis as a proven fact, thus ignoring the very important questions raised by the work of Paul Cohen and others. Finally, and most distressingly, the Hebrew letter aleph is printed upside down at all of its occurrences.--H. P. K. (shrink)
