We are all problem-solvers of some sort. We solve problems to earn a living, get promoted, show that we are smart and deserve colleagues’ respect, and contribute to human progress. Yes, problem-solving is important; the better solution-maker we are, the brighter future we expect. But we are not such good problem solvers for simple reasons: it is hard to define a genuine problem.

To identify and conceptualize research problems in science, philosophers and often scientists rely on classical accounts of problems that focus on intellectual problems defined in relation to theories. Recently, philosophers have begun to study the structures and functions of research problems not defined in relation to theories. Furthermore, scientists have long pursued research problems often labeled as practical or applied. As yet, no account of problems specifies the description of both so-called intellectual problems and so-called applied problems. This article proposes (...) a new conceptual framework of problems that accounts both for intellectual aspects of problems and for their practical or applied aspects. I illustrate the account with an example of a recent research project from evolutionary biology, and I indicate further routes by that to develop the account, especially in connection to empirical studies of science.

The study determined the problem-solving performance and skills of prospective elementary teachers (PETs) in the Northern Philippines. Specifically, it defined the PETs’ level of problem-solving performance in number sense, measurement, geometry, algebra, and probability; significant predictors of their problem-solving performance in terms of sex, socio-economic status, parents’ educational attainment, high school graduated from and subject preference; and their problem-solving skills. The PETs’ problem-solving performance was determined by a problem set consisting of word problems with (...) number sense, measurement, geometry, algebra, and probability. A mixed-method research design was employed. Senior PETs purposively served as a sample where they mostly preferred to teach other subjects than mathematics. PETs who preferred math performed satisfactorily, while prospective teachers who opted for other subjects performed unsatisfactorily. The PETs’ unsatisfactory output indicates the need for remediation to advance the mathematical material skills and enrich the problem-solving abilities of these primary schools' potential teachers. Besides, results showed that subject preference strongly affected and predicted the problem-solving success of the PETs. PETs who preferred to teach mathematics performed significantly better than their counterparts; hence, mathematics as a field of specialization in the Bachelor of Elementary Education program may be considered by teacher education institutions. Further, most PETs displayed lack of problem-solving skills; thus, a Problem-Solving course is recommended for them. (shrink)

In times of crisis, when current theories are revealed as inadequate to task, and new physics is thought to be required—physics turns to re-evaluate its principles, and to seek new ones. This paper explores the various types, and roles of principles that feature in the problem of quantum gravity as a current crisis in physics. I illustrate the diversity of the principles being appealed to, and show that principles serve in a variety of roles in all stages of the (...) crisis, including in motivating the need for a new theory, and defining what this theory should be like. In particular, I consider: the generalised correspondence principle, UV-completion, background independence, and the holographic principle. I also explore how the current crisis fits with Friedman’s view on the roles of principles in revolutionary theory-change, finding that while many key aspects of this view are not represented in quantum gravity, the view could potentially offer a useful diagnostic, and prescriptive strategy. This paper is intended to be relatively non-technical, and to bring some of the philosophical issues from the search for quantum gravity to a more general philosophical audience interested in the roles of principles in scientific theory-change.

Without doubt, terrorism is one of the most vehemently debated subjects in current political affairs as well as in academic discourse. Yet, although it constitutes an issue of general socio-political interest, neither in everyday language nor in professional (political, legal, or academic) contexts does there exist a generally accepted definition of terrorism. The question of how it should be defined has been answered countless times, with as much variety as quantity in the answers. In academic discourse, it is difficult to (...) find two scholars who use the term ‘terrorism’ in the same way. -/- While it is impossible to formulate a definition which satisfies everyone, discussing the definition question is indispensable. The necessity to review existing definitions with a view to improving them is especially obvious in legal and political contexts. How terrorism is defined in these contexts has serious consequences, and if we lack clear definitions we run into problems. How can we have laws or take political measures against something we have not clearly defined? Without doubt, there exists a practical necessity for a definition in these fields. It is important to have clear standards for defining terrorism. -/- In my view, the definition should meet three basic criteria: first, it should cover those cases that we concurrently consider to be instances of terrorism (such as the attacks on the World Trade Center in New York and the Pentagon in September 2001 or those on commuting trains in Madrid Atocha in March 2004). That is, ideally, our definition of terrorism remains close to uncontroversial usages of the term. Second, the definition should abstain from morally judging the act in question. Later I will say more about so called “moral” definitions of terrorism. For now, it suffices to say that defining an action and evaluating it are distinct tasks and should remain so. Third, the definition must identify characteristics that are specific to terrorism alone, characteristics which clearly distinguish it from other phenomena. (shrink)

We are pleased to publish this WSIA edition of Trudy’s Govier’s seminal volume, Problems in Argument Analysis and Evaluation. Originally published in 1987 by Foris Publications, this was a pioneering work that played a major role in establishing argumentation theory as a discipline. Today, it is as relevant to the field as when it first appeared, with discussions of questions and issues that remain central to the study of argument. It has defined the main approaches to many of those issues (...) and guided the ways in which we might respond to them. From this foundation, it sets the stage for further investigations and emerging research. This is a second edition of the book that is corrected and updated by the author, with new prefaces to each chapter. (shrink)

Martha Kuhlman criticizes Milan Kundera for repeatedly depicting crowds in a negative light, contrasting his impressions with that of another novelist and observer of crowds. But how do we define the concept of a crowd? In this slightly light-hearted paper, I propose a definition and then note a problem with it and then propose another definition.

This paper analyses the relations between philosophy of information (PI), library and information science (LIS) and social epistemology (SE). In the first section, it is argued that there is a natural relation between philosophy and LIS but that SE cannot provide a satisfactory foundation for LIS. SE should rather be seen as sharing with LIS a common ground, represented by the study of information, to be investigated by a new discipline, PI. In the second section, the nature of PI is (...) outlined as the philosophical area that studies the conceptual nature of information, its dynamics and problems. In the third section, LIS is defined as a form of applied PI. The hypothesis supported is that PI should replace SE as the philosophical discipline that can best provide the conceptual foundation for LIS. In the conclusion, it is suggested that the 'identity' crisis undergone by LIS has been the natural outcome of a justified but precocious search for a philosophical counterpart that has emerged only recently: namely, PI. The development of LIS should not rely on some borrowed, pre-packaged theory. As applied PI, LIS can fruitfully contribute to the growth of basic theoretical research in PI itself and thus provide its own foundation. (shrink)

It is surprisingly hard to define presentism. Traditional definitions of the view, in terms of tensed existence statements, have turned out not to to be capable of convincingly distinguishing presentism from eternalism. Picking up on a recent proposal by Tallant, I suggest that we need to locate the break between eternalism and presentism on a much more fundamental level. The problem is that presentists have tried to express their view within a framework that is inherently eternalist. I call that (...) framework the Fregean nexus, as it is defined by Frege’s atemporal understanding of predication. In particular, I show that the tense-logical understanding of tense which is treated as common ground in the debate rests on this very same Fregean nexus, and is thus inadequate for a proper definition of presentism. I contrast the Fregean nexus with what I call the original temporal nexus, which is based on an alternative, inherently temporal form of predication. Finally, I propose to define presentism in terms of the original temporal nexus, yielding original presentism. According to original presentism, temporal propositions are distinguished from atemporal ones not by aspects of their content, as they are on views based on the Fregean nexus, but by their form—in particular, by their form of predication.

Accounts of the concepts of function and dysfunction have not adequately explained what factors determine the line between low‐normal function and dysfunction. I call the challenge of doing so the line‐drawing problem. Previous approaches emphasize facts involving the action of natural selection (Wakefield 1992a, 1999a, 1999b) or the statistical distribution of levels of functioning in the current population (Boorse 1977, 1997). I point out limitations of these two approaches and present a solution to the line‐drawing problem that builds (...) on the second one. (shrink)

The article presents the most important systematic philosophical questions and problems regarding altruism, outlines various answers to these, discusses them, develops precise definitions of ‘altruism’ / ‘altruistic’, 'self-interested', 'egoistic', etc. and develops a normative theory of altruism. The starting point is an assumption about the ethical function of the normative concept of altruism, namely that it captures an ideal: acting for the benefit of others beyond one's moral duty. On this basis, the normative concept of altruism is defined. This is (...) followed by an overview of the ethics that explicitly or implicitly advocate altruism. The subsequent discussion of psychological altruism centres on the question of whether and, if so, which human motives may be intrinsically aimed at the good of others. The most important such motive is acting out of empathy. The final section addresses whether and how altruistic action can be rational. (shrink)

This essay examines the concept of leadership as it is commonly understood within the field of leadership studies today. The inquiry is framed by an analysis of three generally accepted definitions of leadership. I look at the selected definitions from four angles, which I call the four dimensions of leadership: the behavioral (what the leader does, or ought to do, that makes it leadership), the asymmetrical (in what sense a leader is different from the others in the group), the social (...) (what it is that the leader is leading), and the teleological (what the direction is). By doing this, I find that these definitions can be problematic, if instructively so. I identify two underlying concerns. The first problem is the tendency to fuse informal and formal leadership into a single concept. I argue that informal and formal leadership can be more helpfully understood, rather, as two separate, if sometimes overlapping, concepts, each needing its own definition and analysis. This is because formal leadership is a functional concept, while informal leadership is not; this entails not only that each type of leader is leading a different type of entity, but also that each is judged by different standards. The second problem is, paradoxically, a bias against leadership. To put this less polemically: scholars who recognize that organizational success can be hindered by excessive emphasis upon hierarchy, and who thus study the dynamics of egalitarian collaboration, can inadvertently generate confusion by allowing the honorific of “leadership” to be applied also to that work. So, I propose definitions of the two key concepts, formal and informal leadership, with the suggestion that this provides a helpful method of sorting leadership scholarship into three categories: formal leadership; informal leadership; and egalitarianism.

defining art conjunctively, that is, by defining the individual arts and joining these definitions in an exhaustive list. I suggest that the individual art forms are no easier to define than is the general category of art. As well, not everything falling within a given art form counts as art, not every instance of art in the given medium falls within the art form, and some artworks do not belong to an art form at all, so conjoining definitions (...) of the individual art forms (supposing they could be defined) would not map the extension of ’art’. Taken together, these problems indicate that the approach advocated here to art’s definition cannot be successful or convincing. (shrink)

Scholars have disagreed on whether Cicero’s De Amicitia is a philosophically serious or even coherent work. Such criticisms, I believe, can be met by an examination of the successive accounts of friendship that the character of Gaius Laelius provides in the dialogue. I argue that the dialogue offers three such accounts of friendship which taken together provide a comprehensive and coherent account of friendship. Further, I defend Cicero’s account against criticisms that Aulus Gellius had raised in the 2nd century CE (...) (criticisms that have been repeated to the modern day). The problem of defining friendship is a thread that brings unity to the entire dialogue and shows Cicero philosophizing about both the origins of friendship and its dissolution, especially when the bonds of friendship are in tension with obligations to the political community.

In this paper we present a new proposal for defining actual causation, i.e., the problem of deciding if one event caused another. We do so within the popular counterfactual tradition initiated by Lewis, which is characterised by attributing a fundamental role to counterfactual dependence. Unlike the currently prominent definitions, our approach proceeds from the ground up: we start from basic principles, and construct a definition of causation that satisfies them. We define the concepts of counterfactual dependence and production, (...) and put forward principles such that dependence is an unnecessary but sufficient condition for causation, whereas production is an insufficient but necessary condition. The resulting definition of causation is a suitable compromise between dependence and production. Every principle is introduced by means of a paradigmatic example of causation. We illustrate some of the benefits of our approach with two examples that have spelled trouble for other accounts. We make all of this formally precise using structural equations, which we extend with a timing over all events. (shrink)

In this article I seek to say what it is for something to count as a neglected disease. I argue that neglect should be defined in terms of efforts at prevention, mitigation and cure, and not solely in terms of research dollars per disability-adjusted life-year. I further argue that the trend towards multifactorialism and risk factor thinking in modern epidemiology has lent credibility to the erroneous view that the primary problem with neglected diseases is a lack of research. A (...) more restrictive contrastive model of disease is endorsed as better suited to the definition of neglected disease. (shrink)

This article brings to bear findings from the debate on the boundary problem in democratic theory on discussions of workplace democracy to argue that workplace democrats’ focus on workers is unjustified and that more constituencies will have to be included in any prospective scheme of workplace democracy. It thereby provides a valuable and underdiscussed perspective on workplace democracy that goes beyond the debate’s usual focus on the clarification and justification of workplace democrats’ core claim. It also goes beyond approaches (...) like stakeholder theory in law and economics that determine decision-making rights without taking into account genuinely democratic considerations. My discussion proceeds by considering three principles for inclusion from democratic theory for the specific case of the corporation. I submit that two of them, the all-coerced and the all-subjected principle, are not appropriate for this specific case, because they cannot capture the distinguishing features of the corporation. The all-affected principle however is appropriate but has a very wide range. I further argue that this is not as big of a problem as it first might seem and that this principle is still the most appropriate for defining the demos of the democratic corporation. The article closes by pointing out the consequences of this result for the workplace democracy debate and for the legitimacy of the market as a coordination mechanism. (shrink)

I systematically defend a novel account of the grounds for identity and distinctness facts: they are all uniquely zero‐grounded. First, this Null Account is shown to avoid a range of problems facing other accounts: a relation satisfying the Null Account would be an excellent candidate for being the identity relation. Second, a plenitudinist view of relations suggests that there is such a relation. To flesh out this plenitudinist view I sketch a novel framework for expressing real definitions, use this framework (...) to give a definition of identity, and show how the central features of the identity relation can be deduced from this definition.

The mind is our most intimate and familiar element of reality, yet also the most mysterious. Various schools of thought propose interpretations of the mind that are consistent with their worldview, all of which face some problems. Some of these problems can be characterised as ``hard'', not in the sense of being difficult to solve (most problems concerning the mind are difficult), but in the sense of being most likely insurmountable: they bring to the surface logical inconsistencies between the reality (...) of the mind as we perceive it and the fundamental metaphysical tenets of that particular worldview, thus putting the latter in danger of being disproven. This essay focuses mainly on the hard problems that the author considers to be of greatest importance for physicalism, the currently prevalent worldview. Nevertheless, some of these hard problems pertain also to otherviews such as panpsychism. In the author's opinion, the hardest and most profound of these, pertaining equally to physicalism and to panpsychism, is the one discussed in Section 4: the particular subjective first-person viewpoint that defines a particular person can be found nowhere in the universe except in that person itself; all outside entities (physical or mental) are equally neutral towards the ``particularity'' of that person, which therefore cannot be explained as arising from any combination of such outside elements. Therefore, a person is a simple substance. Other hard problems discussed concern the physical explanation of conscious experiences and the physical explanation of meaning, while their repercussions with respect to free will and ethics are also examined. Although these latter hard problems have already been discussed elsewhere, a somewhat fresh perspective is given here by someone who is not a professional philosopher but a physical scientist.

The paper identifies defining characteristics of the principal models of problem-solving behavior which are useful in developing a general theory of problem-solving. An attempt is made both to make explicit those disagreements between theorists of different persuasions which have served as obstacles to an integrated approach, and to show that these disagreements have arisen from a number of conceptual confusions: The conflict between information processors and behavioral analysts has resulted from a common failure to understand theoretical sufficiency, (...) and hence these theorists have been at a loss to understand one another. Two directions of research in problem-solving, mechanical algorithmic problem-solving and the psychology of invention, have been thought to be divergent, but in fact complement one another once it is clear that problem-solving involves neither discovery nor invention, but rather is a matter of perceptual encoding and processing. Successful problem-solving behavior can be described as adaptive, learning behavior in which organization skills are effectively associated with situationally determined perceptual encoding processes of the individual mechanical or biological problem-solver.

The “somewhat vague, intuitive” notion from computability theory of an effective procedure (method) or algorithm can be fairly precisely defined even if it is not sufficiently formal and precise to belong to mathematics proper (in a narrow sense)—and even if (as many have asserted) for that reason the Church–Turing thesis is unprovable. It is proved logically that the class of effective procedures is not decidable, i.e., that no effective procedure is possible for ascertaining whether a given procedure is effective. This (...) undecidability result is proved directly from the notion itself of an effective procedure, without reliance on any (partly) mathematical lemma, conjecture, or thesis invoking recursiveness or Turing-computability. In fact, there is no reliance on anything very mathematical. The proof does not even appeal to a precise definition of ‘effective procedure’. Instead, it relies solely and entirely on a basic grasp of the intuitive notion of an effective procedure. Though the result that effectiveness is undecidable is not surprising, it is also not without significance. It has the consequence, for example, that the solution to a decision problem, if it is to be complete, must be accompanied by a separate argument that the proposed ascertainment procedure invariably terminates with the correct verdict.

Finally, I highlight the advantages of my new functional approach over the epistemic (...) and semantic approaches and dismiss some potential objections to my approach. (shrink)

Proficiency in solving mathematical problems is essential for preservice elementary teachers, as they will teach foundational math concepts and foster problem-solving abilities among young learners. However, many studies found low problem-solving performance among preservice teachers. In line with this, the present study examined how problem-solving disposition relates to the performance of preservice elementary teachers, conducted at a selected higher education institution in Nueva Ecija, Philippines, with 134 participants. The study utilized a mathematical problem-solving disposition and beliefs (...) scale questionnaire and a problem-solving test scored using the identify, define, explore, act, and look (IDEAL) model. Results indicated an average problem-solving disposition and high problem-solving performance among preservice teachers. Linear regression analysis showed that overall problem-solving disposition is a predictor of performance. Further, stepwise regression analysis revealed that two disposition parameters, mathematical mindset (β = 2.413, p < 0.01) and community of practice (β = 1.866, p < 0.01), significantly predicted problem-solving performance. These findings show the significance of developing a problem-solving disposition, mindset, and learning communities to improve future teachers’ problem-solving ability by providing more learning opportunities, interdisciplinary problems, and social engagements.

Democracy is rule by the demos, but by what criteria is the demos constituted? Theorists of democracy have tended to assume that the demos is properly defined by national boundaries or by the territorial boundaries of the modern state. In a recent turn, many democratic theorists have advanced the principles of affected interests and coercion as the basis for defining the boundaries of democracy. According to these principles, it is not co-nationals or fellow citizens but all affected or all (...) subjected to coercion who constitute the demos. In this paper, I argue that these recent approaches to the boundary problem are insufficiently attentive to the conditions of democracy. Democracy is not merely a set of procedures; it also consists of substantive values and principles. Political equality is a constitutive condition of democracy, and solidarity is an instrumental condition of democracy. The affected interests and coercion principles create serious problems for the realization of these conditions – problems of size and stability. Building on this critique, this paper presents democratic considerations for why the demos should be bounded by the territorial boundaries of the state, grounded in the state’s role in (1) securing the constitutive conditions of democracy, (2) serving as the primary site of solidarity conducive to democratic participation, and (3) establishing clear links between representatives and their constituents. I examine and reject a third alternative, a global demos bounded by a world state, and conclude by considering some practical implications of my argument. (shrink)

Political scientists' failure to pay careful attention to the content (as opposed to the operationalization) of their chosen definition of 'democracy' can make them liable to draw invalid inferences from their empirical research. With this problem in mind, we argue for the following proposition: if one wishes to conduct empirical research that contributes to an existing conversation about democracy, then one must choose a definition of 'democracy' that picks out the topic of that conversation as opposed to some other (...) (perhaps nearby) topic of conversation. We show that, as a practical matter, one of the most effective methods for preserving "topic continuity" is to choose a definition of `democracy' that concurs with prevailing judgments about how to classify particular regimes, emphasizing the superiority (in this regard) of judgments about stylized hypothetical scenarios as opposed to judgments about the actual regimes we observe in our datasets.

In his influential article ‘Essence and Modality’, Fine proposes a definition of necessity in terms of the primitive essentialist notion ‘true in virtue of the nature of’. Fine’s proposal is suggestive, but it admits of different interpretations, leaving it unsettled what the precise formulation of an Essentialist definition of necessity should be. In this paper, four different versions of the definition are discussed: a singular, a plural reading, and an existential variant of Fine’s original suggestion and an alternative version proposed (...) by Correia which is not based on Fine’s primitive essentialist notion. The first main point of the paper is that the singular reading is untenable. The second that given plausible background assumptions, the remaining three definitions are extensionally equivalent. The third is that, this equivalence notwithstanding, Essentialists should adopt Correia’s version of the definition, since both the existential variant, which has de facto been adopted as the standard version of the definition in the literature, and the plural reading suffer from problems connected to Fine’s primitive essentialist notion.

The problem of demarcating between what is scientific and what is pseudoscientific or merely unscientific - in other words, the problem of defining scientificity - remains open. The modern debate was firstly structured around Karl Popper's falsificationist epistemology from the 1930's, before diversifying a few decades later. His central idea is that what makes something scientific is not so much how adequate it is with data, but rather to what extent it might not have been so. Since (...) the second half of the century, and in the wake of criticisms, such as the Duhem-Quine thesis, that were raised against falsificationism(s), most approaches to the problem of scientific demarcation are now multicriteria and holistic. However, the approach presented in this paper does not follow the same guideline. The present work can be seen as an attempt to adapt Popper's (sophisticated) falsificationism to a model-based view of scientific knowledge. Using formalization and focusing on a particular epistemic unit of analysis (namely, empirical models) allows to properly define the popperian corroboration degree and to view scientificity as the maximization of this degree of corroboration over all available models and data. We eventually recover, in a natural way, well-accepted scientificity criteria: empirical adequacy, Lakatos' progressive problemshifts, balance between strength and simplicity, parsimony, and coherence as special cases of this general scientificity principle. From this viewpoint, the language dependency of our empirical knowledge no longer appears as a limitation of falsificationism but as one more reason to take it as a good epistemological framework.

It causes many difficulties for jurisprudence to define the notion of judicial activism. At the very beginning it had rather a journalistic character, but but over time it has become a serious charge against these judges who act on the basis of their vision of what the law ought to be like rather than what it actually is like. On the ground of the polish legal theory the echoes of the dispute about judicial activism are reflected in the discussions about (...) the nature of legal interpretation. Transposing the problem of activism into the problem of interpretation allows the use of analysis tools that were previously unavailable. One of these tools are concepts emerged on the neopragmatist philosophy of Stanley Fish. Fish tries to describe the nature of the interpretation in the context of reader-response criticism and the concept of interpretive communities. Application of Fish's philosophy in the field of legal theory provides constructive conclusions about the concepts of judicial activism and judicial law-making. (shrink)

An intrinsic property, according to one important account, is a property that is had by all of one's duplicates. Instead, one might choose to characterize intrinsic properties as those that can be had in the absence of all distinct individuals.

The goal is to clarify the rough idea that an intrinsic property is a special sort of non-relational property; having the property does not consist in (...) any relation one bears to distinct individuals.

This paper discusses proof-theoretic semantics, the project of specifying the meanings of the logical constants in terms of rules of inference governing them.

I point out a problem for defining the meaning of negation in this framework and prospects for an account of the (...) meanings of modal operators in terms of rules of inference. (shrink)

The argument of this dissertation is that despite the intellectual gendered burden of the problem of disembodiment I define, it can be employed from within the limitations of a gendered account in feminist philosophy of the continental-realist type. I formulate the problem of disembodiment as rooted in the notion of the boundless (apeiron) associated with femininity. Both boundlessness and disembodiment are subject to radicalization in Plato (chōra) and Plotinus (to hen). Read as a dyad, they culminate in a (...) tendency towards gendered disembodiment, mediated by Plato’s soul-body dualism. The dissertation seeks to compare the gendered dimension of disembodiment in the work of Plato and Plotinus and that of the non- philosophers François Laruelle and Katerina Kolozova. “Part I. The Problem of Boundlessness: Radicalizing Disembodiment” is divided in three chapters, which present an intellectual history of the problem of boundlessness as femininity. I survey the problem of boundlessness as drafting relations between elements and principles and femininity in Greek mythology (Chapter 1), Plato’s cosmology (Chapter 2), and Plotinus’ metaphysics (Chapter 3). I argue that the relation between death and the female was ambivalent by the time of the Anaximandrean apeiron and that it became a subject of radicalization via Plato’s chōra and Plotinus’ One, mediated by the notion of the Indefinite Dyad and the doctrine of divided matter. The problem of boundlessness was subject to conceptual radicalization that led to hierarchical metaphysics and deepened the division between body and soul via the association of femininity, reproductivity and matter. “Part II. The Problem of Disembodiment: Revising Boundlessness” is divided in two chapters focusing on the contemporary relevance and importance of the problem of disembodiment as a way of revising boundlessness. I present and explain the legacy of the Platonic chōra and the Plotinian One and what they as a dyad entail for contemporary continental philosophy. I offer (Chapter 4) a trajectory for a continental feminist philosophy interpretation of disembodiment by combining continental feminist philosophy, non- philosophy and new realism. With the aid of Laruelle’s non-philosophy, I explain how and why chōra and the One can be used for/from continental feminist philosophy, followed by a presentation of how chōra and the One are revised in continental philosophy from non- philosophical and new realist perspectives. I then develop (Chapter 5) a continental feminist philosophical interpretation of and approach to the problem of disembodiment from a realist perspective by problematizing continental and feminist philosophical anti-realism. The approach presented is itself an argument in defence of a feminist engagement with disembodiment and the dissertation’s contribution: a non-philosophical contribution to the problem of disembodiment via a continental feminist-realist philosophical approach. The approach is offered through the intersection of continental feminist realism and non- philosophy, and partially new realism. My conclusion is that an affirmative project and consideration of disembodiment for continental feminist philosophy is possible via a non- philosophical and new realist reconsideration of the One.

This volume focuses on philosophical problems concerning sense perception in the history of philosophy. It consists of thirteen essays that analyse the philosophical tradition originating in Aristotle’s writings. Each essay tackles a particular problem that tests the limits of Aristotle’s theory of perception and develops it in new directions. The problems discussed range from simultaneous perception to causality in perception, from the representational nature of sense-objects to the role of conscious attention, and from the physical/mental divide to perception as (...) quasi-rational judgement. -/- The volume gives an equal footing to Greek, Arabic, and Latin philosophical traditions. It makes a substantial contribution not just to the study of the Aristotelian analysis of sense perception, but to its reception in the commentary tradition and beyond. Thus, the papers address developments in Alexander of Aphrodisias, Themistius, Avicenna, John of Jandun, Nicole Oresme, and Sayf al-Din al-Amidi, among others. The result of this is a coherent collection that attacks a well-defined topic from a wide range of perspectives and across philosophical traditions. (shrink)

What are consequential world problems? As “grand societal challenges”, one might define them as problems that affect a large number of people, perhaps even the entire planet, including problems such as climate change, distributive justice, world peace, world nutrition, clean air and clean water, access to education, and many more. The “Sustainable Development Goals”, compiled by the United Nations, represent a collection of such global problems. From my point of view, these problems can be seen as complex. Such complex problems (...) are characterized by the complexity, connectivity, dynamics, intransparency, and polytely of their underlying systems. These attributes require special competencies for dealing with the uncertainties of the given domains, e.g., critical thinking. My position is that it is not IQ, but complex problem-solving competencies for dealing with complex and dynamic situations, that is important for handling consequential global problems. These problems require system competencies, i.e., competencies that go beyond analytical intelligence, and comprise systems understanding as well as systems control. Complex problem-solving is more than analytic intelligence. (shrink)

The independence problems for functionalism stem from the worry that if functional properties are defined in terms of their causes and effects then such functional properties seem to be too intimately connected to these purported causes and effects. I distinguish three different ways the independence problems can be filled out – in terms of necessary connections, analytic connections and vacuous explanations. I argue that none of these present serious problems. Instead, they bring out some important and over-looked features of functionalism.

This thesis is an argument for the view that there are problems for Modal Reductionism, the thesis that modality can satisfactorily be defined in non-modal terms. -/- I proceed via a case study of David Lewis’s theory of concrete possible worlds. This theory is commonly regarded as the best and most influential candidate reductive theory of modality. Based on a detailed examination of its ontology, analysis and justification, I conclude that it does badly with respect to the following four minimal (...) conditions on a satisfactory reductive theory of modality: that it be (a) genuinely reductive, (b) materially adequate, (c) conceptually adequate and (d) that its justification provides good reason to think it true. -/- These problems for Lewis’s theory are not, I suggest, due to his idiosyncratic conception of possible worlds as concrete entities. Rather, because Lewis’s theory can be seen to represent an important class of structurally similar reductive theories of modality, the problems for Lewis’s theory generalise to problems for these other theories. This suggests that Modal Reductionism is unpromising. In the light of this, the alternative approach to understanding modality, Modal Primitivism, appears more attractive. (shrink)

This essay presents a point of view for looking at `free will', with the purpose of interpreting where exactly the freedom lies. For, freedom is what we mean by it. It compares the exercise of free will with the making of inferences, which usually is predominantly inductive in nature. The making of inference and the exercise of free will, both draw upon psychological resources that define our ‘selves’. I examine the constitution of the self of an individual, especially the involvement (...) of personal beliefs, personal memories, affects, emotions, and the hugely important psychological value-system, all of which distinguish the self of one individual from that of another. The foundational position that adopted in this essay is that all psychological processes are correlated with corresponding ones involving large scale neural aggregates in the brain, communicating with one another through wavelike modes of excitation and de-excitation. Of central relevance is the value-network around which the affect system is organized, the latter, in turn, being the axis around which is assembled the self, with all its emotional correlates. The self is a complex system. I include a brief outline of what complexity consists of. In reality all systems are complex, for complexity is ubiquitous, and certain parts of nature appear to us to be ‘simple’ only in certain specific contexts. It is in this background that the issue of determinism is viewed in this essay. Instead of looking at determinism as a grand principle entrenched in nature independent of our interpretation of it, I look at our ability to explain and to predict events and phenomena around us, which is made possible by the existence of causal links running in a complex course that set up correlations between diverse parts of nature, in this way putting the stamp of necessity on these events. However, the complexity of systems limits our ability to explain and to predict to within certain horizons defined by contexts. Our ability to explain and predict in matters relating to acts of free will is similarly limited by the operations of the self that remain hidden from our own awareness. The aspects of necessity and determinism appear to us in the form of reason and rationality that explain and predict only within a limited horizon, while the rest depends on the complex operation of self-linked psychological resources, where the latter appear as contingent in the context of the exercise of free will. The hallmark of complex systems is the existence of amplifying factors that operate as destabilizing ones, along with inhibiting or stabilizing factors as well that generally limit the destabilizing influences to local occurrences, while preserving the global integrity of a system. This complex interplay of destabilizing and stabilizing influences lead to the possibility of an enormous number of distinct modes of behavior that appear as emergent phenomena in complex systems. Looking at the particular case of the self of an individual that guide her actions and thoughts, it is the operation of our emotions, built around the psychological value-system, that provide for the amplifying and inhibiting factors mentioned above. The operation of these self-linked factors stamps our actions and thoughts as contingent ones that do not fit with our concepts of reason and rationality. And this is what provides the basis of our idea of free will. Free will is not ‘free’ in virtue of exemption from causal links running through all our self-based processes - ones that remain hidden from our awareness, but is free of what is perceived to be ‘reason and rationality’ based on knowledge and the common pool of beliefs and principles associated with a shared world-view. When we speak of the choice involved in an act of exercise of free will what we actually refer to is the commonly observed fact that various different individuals of a similar disposition respond differently when placed under similar circumstances. In other words, free will is ‘free’ precisely because it is not subject to constraints of a commonly accepted and shared set of principles, beliefs, and values. While it is possible that, in an exercise of free will, the self-linked psychological resources are brought into action when a number of alternatives are presented to the self by the operation of the ingredients of a commonly shared world-view, it seems likely that, that set of alternatives is not of primary relevance in the final response that the mind produces, since the latter is primarily a product of the operation of the self-based psychological resources. What is of greater relevance here is the operation of emotion-driven processes, guided by the psychological value-system based on the activity of the so-called reward-punishment network in the brain. These processes lead the individual to a response that appears to be free from the shackles of determinism precisely because their mechanisms, which are hidden from us, do not conform to commonly accepted and shared rules and principles. In contrast, inductive inference is a process that is based on the ‘cognitive face’ of self, where the self-based psychological resources play a supportive role to the commonly shared world-view of an individual. There is never any freedom from the all-pervading causal links representing correlations among all objects, entities, and events in nature. In the midst of all this, the closest thing to freedom that we can have in our life comes with self-examination and self-improvement. The possibility of self-examination appears in the form of specific conjunctions between our complex self-processes and the ceaseless changes of scenario in our external world. This actually makes the emergent phenomenon of self-examination a matter of chance, but one that keeps on appearing again and again in our life. Once realized, self examination creates possibilities that would not be there in the absence of it, and these possibilities include the enhancement of further self-enrichment and further diversity in the exercise of our free will.

In this paper, I articulate and defend a conception of trust that solves what I call “the trickster problem.” The problem results from the fact that many accounts of trust treat it similar to, or identical with, relying on someone’s good will. But a trickster could rely on your good will to get you to go along with his scheme, without trusting you to do so. Recent philosophical accounts of trust aim to characterize what it is for one (...) person to trust another so as to avoid this problem, but no extant account successfully does so. I argue that connecting trust to important, normatively defined relationships like friendship, romantic partnerships and parenting shows us something important about trust. The clearest cases of trust are found within the confines of normatively defined relationships like these, suggesting that there is a normative element to trust. Trusting someone involves not just believing that another person’s good will covers your interactions. Trusting involves believing that, at least in a certain domain of interaction, you are entitled to rely on that person’s good will. This account solves the trickster problem, because a trickster is not entitled to his victim’s good will. (shrink)

The article deals with the problem of cognition in the framework of the biogenetic structuralist neurophenomenology of Charles Laughlin. The aim of the article is to study the possibilities of applying the biogenetic structuralist theory as a theoretical and methodological basis for the study of consciousness in Laughlin’s theory. A feature of biogenetic structuralism is the interdisciplinary fusion of anthropology, psychology, and neuroscience. The methodology of biogenetic structuralism allows exploring universal structures of consciousness, which are caused by the genetically (...) predisposed organization of the human nervous system. Universal structures of consciousness include structures that mediate human language, knowledge of time and space. It is shown that the problem of cognition is realized in neurognostic models, which are compared with the operational environment. Neurognostic models include both the real nature of man as an organism and the external environment of the organism. Laughlin introduces the concept of a cognitive environment to designate a set of neurognostic models that can potentially be captured by the area of consciousness. He relies on the idea of a cognitive environment, which is essentially intentional in its organization. The polar interaction between the prefrontal cortex and the sensory cortex of the human brain gives rise to the intentionality of consciousness. Laughlin explains the work of the human cerebral cortex neurognostically as omnipresent for human consciousness, and independent of the cultural background. The cerebral cortex is a field of neural activity that arises and dissolves in temporal sequences and coordinates with cognitive processes that connect meaning and form into a single structure in consciousness. The experience of consciousness suggests a sensitive sphere of the cerebral cortex ascertains the meaningful, phenomenal world. The biogenetic structuralist methodology allows to development of an idea of the intentional structure and uniqueness of consciousness. The biogenetic structuralist approach is heuristic for modern science because, firstly, this approach creates the maximum opportunity to include data obtained from naturalistic, ethnographic, anatomical, clinical, and experimental sources; secondly, biogenetic data have the widest empirical and phenomenological rationale; thirdly, biogenetic concepts are defined in the context of a holistic understanding of the phenomenon through the uniqueness of consciousness.

We develop a novel solution to the negation version of the Frege-Geach problem by taking up recent insights from the bilateral programme in logic. Bilateralists derive the meaning of negation from a primitive *B-type* inconsistency involving the attitudes of assent and dissent. Some may demand an explanation of this inconsistency in simpler terms, but we argue that bilateralism’s assumptions are no less explanatory than those of *A-type* semantics that only require a single primitive attitude, but must stipulate inconsistency elsewhere. (...) Based on these insights, we develop a version of B-type expressivism called *inferential expressivism*. This is a novel semantic framework that characterises meanings by inferential roles that define which *attitudes* one can *infer* from the use of terms. We apply this framework to normative vocabulary, thereby solving the Frege-Geach problem generally and comprehensively. Our account moreover includes a semantics for epistemic modals, thereby also explaining normative terms under epistemic modals. (shrink)

We study active set methods for optimization problems in Block Angular Form (BAF). We begin by reviewing some standard basis factorizations, including Saunders' orthogonal factorization and updates for the simplex method that do not impose any restriction on the pivot sequence and maintain the basis factorization structured in BAF throughout the algorithm. We then suggest orthogonal factorization and updating procedures that allow coarse grain parallelization, pivot updates local to the affected blocks, and independent block reinversion. A simple parallel environment appropriate (...) to the description and complexity analysis of test procedures is defined in Section 5. The factorization and updating procedures are presented in Sections 6 and 7. Our update procedure outperforms conventional Updating procedures even in a purely sequential environment. (shrink)

Online identification is a common problem but so far resolved unsatisfactorily, as consumers cannot fully control how much data they share and with whom. Self-Sovereign Identity (SSI) technology promises to help by making use of decentralized data repositories as well as advanced cryptographic algorithms and protocols. This paper examines the effects of SSIs on responsible, confident, and vulnerable consumers in order to develop the missing understanding of consumer needs in SSI adoption and define preconditions and necessary considerations for the (...) development of SSI-based platforms and applications.

In this article I propose a new problem for the classical analysis of knowledge (as justified true belief) and all analyses belonging to its legacy. The gist of my argument is that truth as a condition for a belief to be knowledge is problematic insofar there is no definition of truth. From this, and other remarks relating to the possibility of defining truth (or lack thereof) and about what truth theories fit our thoughts about knowledge, I conclude that (...) as long as truth is unquestioningly taken as a condition of knowing, knowledge can never be defined in a way that could satisfy our intuitions about it.

Despite its enormous practical success, many physicists and philosophers alike agree that the quantum theory is full of contradictions and paradoxes which are difficult to solve consistently. Even after 90 years, the experts themselves still do not all agree what to make of it. The area of disagreement centers primarily around the problem of describing observations. Formally, the so-called quantum measurement problem can be defined as follows: the result of a measurement is a superposition of vectors, each representing (...) the quantity being observed as having one of its possible values. The question that has to be answered is: how this superposition can be reconciled with the fact that in practice we only observe one value. How is the measuring instrument prodded into making up its mind which value it has observed? Among some alternatives to resolve the above QM measurement problem, a very counterintuitive one was suggested by Hugh Everett in his 1955 Princeton dissertation, which was subsequently called the Many-Worlds Interpretation of QM (MWI). In this paper we will not discuss all possible scenarios to solve the measurement problem, but we will only shortly discuss Everett’s MWI, because it has led to heated debates on possibility of multiverses, beyond the Universe we live in. We also discuss two alternatives against MWI proposal: (a) the so-called scale symmetry theory, (b) the Maxwell-Dirac isomorphism. In last section, we also discuss shortly MWI hypothesis from philosophical perspective. (shrink)

Intentionality is traditionally defined as the property of a mental state to be directed at something presented in a particular way. The fact that we can think about objects which do not exist makes this definition problematic: what kind of things are those objects? The aim of this paper is to analyse the definition of intentionality as a relation in theories which do not admit non-existent special entities. In particular, I consider John R. Searle and Tim Crane’s theories of intentionality (...) and I argue that neither Searle’s notion of a non-ordinary relation between the intentional state and the intentional object nor Crane’s idea of a relation between the intentional state and the intentional content succeed in holding together the traditional definition of intentionality and the purpose to not be committed to some kind of special entities. This intent seems finally hardly compatible with the traditional definition of intentionality. (shrink)

The aim of the article is to explore Thomas Kuhn’s notion of “scientific crisis” and indicate some difficulties with it. First, Kuhn defines “crisis” through the notion of “anomaly” but distinguishes these concepts in two different ways: categorically and quantitatively. Both of these alternatives face considerable problems. The categorical definition relies on a distinction between “discoveries” and “inventions” that, as Kuhn himself admits, is artificial. The quantitative definition states that crises are a deeper, more profound type of anomaly. Kuhn, however, (...) does not offer any criteria for objectively defining this “severity” of the crises. The second kind of problem is related to the application of the concept of “crisis.” Apparently, Kuhn attributes crises to individuals as much as to communities. Lastly, there is the problem of the function of crises. In The Structure of Scientific Revolutions, they are presented as a precondition to scientific revolutions. In later articles, however, Kuhn seems to see them only as a common antecedent to revolutions. (shrink)

The quantum measurement problem is one of the most profound challenges in modern physics, questioning how and why the wavefunction collapses during measurement to produce a single observable outcome. In this paper, we propose a novel solution through a logical framework called Aethic reasoning, which reinterprets the ontology of time and information in quantum mechanics. Central to this approach is the Aethic principle of extrusion, which models wavefunction collapse as progression along a Markov chain of block universes, effectively decoupling (...) the Einsteinian flow of time from quantum collapse events. This principle introduces an additional degree of freedom to time, enabling the first Aethic postulate: that informational reality is reference-dependent, akin to the relativity of simultaneity in special relativity. This reference point, or Aethus, is rigorously defined within a mathematical structure. Building on this foundation, the second postulate resolves the distinction between quantum superpositions and logical contradictions by encoding superpositions in a “backend” Aethic framework before rendering observable states. The third postulate further distinguishes quantum coherence from decoherence using a two-generational model of state inheritance, potentially advancing beyond simpler interpretations of information leakage. Together, these postulates yield a direct theoretical derivation of the collapse postulate, fully consistent with empirical results such as the outcome of the double-slit experiment. By addressing foundational aspects of quantum mechanics through a logically robust and philosophically grounded lens, this framework sheds new light on the measurement problem and offers a solid foundation for future exploration.

This investigation concerns first what Jacques Derrida and Paul Ricœur consider to be «the question of writing» in Plato’s Phaedrus, and then whether their conception of a general philosophical problem of writing finds support in the dialogue. By contrast to their attempts to «determine» the «status» of writing as the general condition of knowledge, my investigation has two objections. (1) To show that Plato’s concern is not to define writing, but to reflect on what is involved in honest and (...) dishonest inquiry. (2) To argue that Derrida’s and Ricœur’s determination of the instrumental (epistemic and moral) «status» of writing, overlooks crucial difficulties of dishonest writing that Plato’s discussion of the pharmakon reveals. The argument proposed is that honest and dishonest inquiry is not tied to the moral status that writing, as an invention or instrument, unconditionally involves, but to the moral quality of what a human being does when inquiring.
