The article discusses the allegedly decontextualized and ahistorical traits in positivist educational research and curriculum by examining its emergence in early twentieth-century empirical education. Edward Lee Thorndike’s educational psychology is analyzed as a case in point. It will be shown that Thorndike’s positivist educational psychology stressed the need to account for the reality of schooling and to produce knowledge of the actual contexts of education. Furthermore, a historical analysis informed by Michel Foucault’s history of the human sciences reveals that there (...) are multiple historical temporalities involved in Thorndike’s educational psychology. This allows a new critical angle to be taken on positivist educational research. The question concerning the contexts of empirical education turns to examining the way the conditions of possibility for scientific knowledge in education involve practices of contextualization as well as paradoxical and self-defeating elements.

Self-cultivation—taking pedagogical action to educate oneself—is an integral part of non-formal adult education. Ever since Greek antiquity, it has been a central ingredient in the western philosophical and educational tradition. However, we argue that the global challenges that have emerged in the present era of the ecological crisis call for a new kind of understanding of this basic educational phenomenon. Based in particular on recent work in dark ecology and its central concept of the ‘uncanny’, we outline a few key (...) features of our time in relation to the contemporary challenge of self-cultivation. We then review extant literature on self-cultivation to ascertain whether the theoretical resources that have been used to conceptualise it in the past are capable of addressing these new aspects of self-cultivation. We conclude that each of the theoretical resources analysed here offer valuable insights into the novel challenges facing self-cultivation, though not all important questions can be answered. By specifying the contributions and limitations of these theoretical resources, we pave the way for future work on conceptualising self-cultivation for our times. (shrink)

Images of brains circulate today as rationales for decision-making and selectivity in policies, curriculum, preservice teacher education and inservice professional development. The excitement over brain-based research, its visual reach and authorizing role accompanies longstanding debates in which the status attributed to biology, physiology and allied psychological approaches has been considered prejudicial. This article traces a series of dislocations in the linkages forged between discourses of vision and epistemic authorization, and how they still inhere in contemporary debates over brain imaging. The (...) critical history that the article offers within the general framework of Visual science and technology studies requires questioning some of the core tenets of visual culture, including what gets to count as the visual, ‘its’ role in legitimation, and the primacy assigned to looking and observation as strategies of truth-production.

The 21st century is steeped in claims to interconnection, technological innovation, and new affective intensities amid challenges to the primacy and centrality of 'the human'. Flashpoint epistemology attends to the lived difficulties that arise in teaching, policymaking, curriculum and research among continuous practices of differentiation, and for which there is no pre-existing template for judgment, resolution or action. Flashpoint Epistemology Volume 1 examines contemporary collisions and reworkings of cultural-political issues in education through arts and humanities-based approaches. How and whether lines (...) are (re)drawn in educational practice - and via who-what - between justice, morality, religion, ethics, subjectivities, intersectionality, the sublime and the senses are a particular focus. The volume offers innovative relational approaches and new narrativization strategies, examining the aporia experienced when operating in educational domains of inevitable, recurring, difficult, fortuitous and/or unforeseen flashpoints. The chapters will engage researchers seeking new approaches to education's complexities, nested discourses, and ever-moving horizons of enactment. It will also benefit post/graduate students and teachers whose work intersects with sociological, philosophical and cultural studies and who are curious about claims to interconnection, the ethical quandaries embedded in practice, and the affordances and limits of technological innovation.

Very plausibly, there is something important missing in our lives if we are thoroughly ignorant or misled about reality – even if, as in a kind of Truman Show scenario, intervention or fantastic luck prevents unhappiness and practical failure. But why? I argue that perfectionism about well-being offers the most promising explanation. My version says, roughly, that we flourish when we exercise our self-defining capacities successfully according to their constitutive standards. One of these self-defining capacities, or capacities whose exercise reveals (...) who we are, is Reason, our capacity for normative self-governance. I argue that in its practical use, Reason formally aims at competently realizing self-chosen valuable ends that are in harmony with each other, or valuable achievements. In its theoretical use, it formally aims at competently grasping fundamental enough subject matters, or a kind of understanding. Because success by reason’s own standards requires many things to go right, there are many different ways in which we can fall short. Some of them amount to partial success. But some, like incompetent inquiry that fails to yield understanding of its target, or taking inefficient means to a worthless end, are robust failures that amount to epistemic or agential unflourishing, and thus to a form of ill-being.

While suicide is typically associated with personal despair, people do sometimes kill themselves in the hope or expectation that their death will advance a political cause by way of its impact on the conscience of others, or in extreme cases simply as an expression of protest against a status quo felt to be unjust. Paradigm cases of such protest suicide may be public acts of self-immolation. This chapter distinguishes between instrumental and expressive protest suicide, examines the possible motivations behind them, (...) their possible moral justification, and their potential contribution to the meaning of the suicide’s life. It argues that when the value of the aim pursued by way of instrumental suicide is proportionate, killing oneself promotes it sufficiently, and other morally acceptable options are exhausted, instrumental protest suicide can be morally permissible and consistent with human dignity. It can even be an admirable act of self-sacrifice, provided that the agent’s motivations are suitable. Some of the standard moral objections to suicide don’t apply to such cases. But protest suicide remains morally risky, because one might be mistaken about the worth of one’s cause or the availability of alternatives, and because even these extreme acts typically have limited effect.

This chapter presents two contemporary pictures of practical reasoning. According to the Rule-Guidance Conception, roughly, practical reasoning is a rule-guided operation of acquiring (or retaining or giving up) intentions so as to meet synchronic requirements of rationality. According to the Reasons-Responsiveness Conception, practical reasoning is a process of responding to reasons we take ourselves to have, and its standards of correctness derive from what we objectively have reason to do, if things are as we suppose them to be. I argue (...) that a version of the latter has some significant advantages. This has some surprising consequences for how we should conceive of the structure of instrumental reasoning in particular.

In this paper, I examine six arguments concerning or making use of empirical psychological evidence in metaethics and normative ethics. Generally speaking, I find that the ambitious ones fail and the more modest ones ought to moderate their conclusions further.

The central question of the branch of metaethics we may call philosophical moral psychology concerns the nature or essence of moral judgment: what is it to think that something is right or wrong, good or bad, obligatory or forbidden? One datum in this inquiry is that sincerely held moral views appear to influence conduct: on the whole, people do not engage in behaviours they genuinely consider base or evil, sometimes even when they would stand to benefit from it personally. Moral (...) judgments thus appear to be motivationally effective, at least to an extent. This motivational success would be readily explained if they simply were motivationally effective psychological states, such as desires. This is what Hobbes seems to do when he claims that "whatsoever is the object of any man's appetite or desire, that is it which he for his part calleth good; and the object of his hate and aversion, evil."1 But this is far too quick. We know that moral judgments can also fail to lead to corresponding action. For example, since it is conceptually possible – not to mention all too common in the actual world – to think that something is wrong and yet want to do it, thinking that something is wrong cannot simply consist in aversion toward it, unlike Hobbes seems to have thought. In this way, reflection on the various.. (shrink)

Abstract In this paper I discuss Polycarp Ikuenobe's view that it is rational to believe, in an African context, in the existence of witches and witchcraft. First, I attempt to show that it is not possible to prove empirically that witches and witchcraft are real, as Ikuenobe assumes. I argue that even though witches and witchcraft are part of the social reality in which many Africans live, they do not have the same ontological status as theoretical entities in scientific research. (...) Second, I try to show that Ikuenobe's attempt to demonstrate that the belief in witches and witchcraft has a rational foundation is not convincing. Admittedly, Africans, who live in magic-ridden cultures, have reasons that locally justify their belief in witches and witchcraft. However, when the justification offered for this belief is assessed by external standards, employed within scientific discourse, it turns out to be insufficient. (shrink)

In considering the lodestars of American neoconservative thought-among them Irving Kristol, Gertrude Himmelfarb, James Q. Wilson, and Francis Fukuyama-Antti Lepistö makes a compelling case for the centrality of their conception of "the common man" in accounting for the enduring power and influence of their thought. Lepistö locates the roots of this conception in the eighteenth-century Scottish Enlightenment. Subsequently, the neoconservatives weaponized the ideas of Adam Smith, Thomas Reid, and David Hume to denounce postwar liberal elites, educational authorities, and social (...) reformers-ultimately giving rise to a defining force in American politics: the "common sense" of "the common man.".

Educational Theory, Volume 71, Issue 6, Page 717-741, December 2021. -/- Gert Biesta has criticized Anglo-American and German models of emancipatory education. According to Biesta, emancipation is understood in these models as liberation that results from a process in which a teacher transmits objective knowledge to his or her students and cultivates student capabilities. He claims that this so-called modern logic of emancipation does not lead to freedom because it installs inequality, dependency, and mistrust in the pedagogical relationship. In this (...) article, Antti Moilanen and Rauno Huttunen analyze whether German models of emancipatory education share the modern logic of emancipation and if they can escape Biesta's criticisms. For this purpose, they interpret Biesta's critique of the modern logic of emancipation and explicate central ideas related to the German models of critical education. They also compare the modern logic of emancipation to the German one, and they then assess German models of emancipatory pedagogy from the viewpoint of Biesta's criticisms. Moilanen and Huttunen conclude that the German models of emancipatory education present at least a partial alternative to the modern logic of emancipation. Despite this, the German models are based on the idea of education as cultivation. Because Biesta criticizes the theory of education as cultivation, it is possible to conclude that he would not accept the German models of emancipatory education. However, the German models of critical pedagogy provide answers to the following question: how can students achieve independence in the pedagogical relationship? When students take part in designing educational processes, they are summoned to assess the validity of the taught knowledge, and they practice independent decision-making at school; the pedagogical relationship, based on authority, can foster student self-determination.

The purpose of this paper is to give a semantical analysis of why-questions. Why-questions will be construed as requests for knowledge. Special attention will be paid to considering what the conditions for conclusive answerhood are in the case of why-questions. Since explanations can often be thought of as answers to why-questions, we also discuss some topics in the theory of explanation.

Malcolm-Smith, Solms, Turnbull and Tredoux [Malcolm-Smith, S., Solms, M.,Turnbull, O., & Tredoux, C. . Threat in dreams: An adaptation? Consciousness and Cognition, 17, 1281–1291.] have made an attempt to test the Threat-Simulation Theory , a theory offering an evolutionary psychological explanation for the function of dreaming [Revonsuo, A. . The reinterpretation of dreams: An evolutionary hypothesis of the function of dreaming. Behavioral and Brain Sciences, 23, 877–901]. Malcolm-Smith et al. argue that empirical evidence from their own study as well as (...) from some other studies in the literature does not support the main predictions of the TST: that threatening events are frequent and overrepresented in dreams, that exposure to real threats activates the threat-simulation system, and that dream threats contain realistic rehearsals of threat avoidance responses. Other studies, including our own, have come up with results and conclusions that are in conflict with those of Malcolm-Smith et al. In this commentary, we provide an analysis of the sources of these disagreements, and their implications to the TST. Much of the disagreement seems to stem from differing interpretations of the theory and, consequently, of differing methods to test it. (shrink)

How can we figure out what’s right or wrong, if moral truths are neither self-evident nor something we can perceive? Very roughly, the method of reflective equilibrium (RE) says that we should begin moral inquiry from what we already confidently think, seeking to find a a match between our initial convictions and general principles that are well-supported by background theories, mutually adjusting both until we reach a coherent outlook in which our beliefs are in harmony (the equilibrium part) and we (...) know why and how they support each other (the reflective part). It has been central to the self-understanding of normative ethics and other branches of philosophy in the last half a century. In this chapter, we examine the history of the idea of RE and introduce a schema for generating 256 variants. We explain why RE is subject to serious objections insofar as it purports to yield epistemic justification in virtue of achieving coherence. However, we also develop a new argument to the effect that RE is the best feasible method for us to achieve moral understanding and the ability to justify our judgments to others. It may thus be crucial for responsible moral inquiry, even if coherence among considered judgments and principles is neither sufficient nor necessary for justified moral belief. (shrink)

Grandparental presence is known to correlate with the number of grandchildren born, and this effect may vary according to grandparental sex and lineage. However, existing studies of grandparental effects on fertility mostly concern traditional subsistence societies, while evidence from contemporary developed societies is both scarce and mixed. Here, we explore how grandparents affect the transition to second and subsequent children in the contemporary United Kingdom. The longitudinal Millennium Cohort Study (n = 10,295 families) was used to study the association between (...) grandparental investment and parents’ probability of having a new child within 4.5 years. Results show that contact with paternal grandparents is associated with higher probability of parents having a second child. In contrast, contact with maternal grandparents is associated with lower probability of having a third or subsequent child. Kin may have opposite effects on fertility even in contemporary societies, which may explain the lack of consistent effects of grandparental investment on fertility in previous studies. (shrink)

We investigate extensions of dependence logic with generalized quantifiers. We also introduce and investigate the notion of a generalized atom. We define a system of semantics that can accommodate variants of dependence logic, possibly extended with generalized quantifiers and generalized atoms, under the same umbrella framework. The semantics is based on pairs of teams, or double teams. We also devise a game-theoretic semantics equivalent to the double team semantics. We make use of the double team semantics by defining a logic (...) $$\hbox {DC}^2$$ DC 2 which canonically fuses together two-variable dependence logic $$\hbox {D}^2$$ D 2 and two-variable logic with counting quantifiers $$\hbox {FOC}^2$$ FOC 2 . We establish that the satisfiability and finite satisfiability problems of $$\hbox {DC}^2$$ DC 2 are complete for $$\hbox {NEXPTIME}$$ NEXPTIME. (shrink)

Paul Celan wasfamiliar with all these uses of name and addresses them in his poeticsand poetry.

Directed acyclic graphs (DAGs) constitute a qualitative representation for conditional independence (CI) properties of a probability distribution. It is known that every CI statement implied by the topology of a DAG is witnessed over it under a graph-theoretic criterion of d-separation. Alternatively, all such implied CI statements are derivable from the local independencies encoded by a DAG using the so-called semi-graphoid axioms. We consider Labeled Directed Acyclic Graphs (LDAGs) modeling graphically scenarios exhibiting context-specific independence (CSI). Such CSI statements are modeled (...) by labeled edges, where labels encode contexts in which the edge vanishes. We study the problem of identifying all independence statements implied by the structure and the labels of an LDAG. We show that this problem is coNP-hard for LDAGs and formulate a sound extension of the semi-graphoid axioms for the derivation of such implied independencies. Finally we connect our study to certain qualitative versions of independence ubiquitous in database theory and teams semantics. (shrink)

A “conceptual spaces” approach is used to formalize Aristotle’s main intuitions about time and change, and other ideas about temporal points of view. That approach has been used in earlier studies about points of view. Properties of entities are represented by locations in multidimensional conceptual spaces; and concepts of entities are identified with subsets or regions of conceptual spaces. The dimensions of the spaces, called “determinables”, are qualities in a very general sense. A temporal element is introduced by adding a (...) time variable to state functions that map entities into conceptual spaces. That way, states may have some permanency or stability around time instances. Following Aristotle’s intuitions, changes and events will not be necessarily instant phenomena, instead they could be processual and interval dependent. Change is defined relatively to the interval during which the change is taking place. Time intervals themselves are taken to represent points of view. To have a point of view is to look at the world as it is in the selected interval. Many important concepts are relativized to intervals, for instance change, events, identity, ontology, potentiality, etc. The definition of points of view as intervals allows to compare points of view in relation to all these concepts. The conceptual space approach has an immediate semantic and structural character, but it is tempting to develop also logics to describe them. A formal language is introduced to show how this could be done. (shrink)

An overview and critical analysis of the study of consciousness, integrating findingsfrom philosophy, psychology, and cognitive neuroscience into a unified theoreticalframework.

It is not uncommon to be frustrated by the outcome of an election or a decision in voting, law, economics, engineering, and other fields. Does this 'bad' result reflect poor data or poorly informed voters? Or does the disturbing conclusion reflect the choice of the decision/election procedure? Nobel Laureate Kenneth Arrow's famed theorem has been interpreted to mean 'no decision procedure is without flaws'. Similarly, Nobel Laureate Amartya Sen dashes hope for individual liberties by showing their incompatibility with societal needs. (...) This highly accessible book offers a new, different interpretation and resolution of Arrow's and Sen's theorems. Using simple mathematics, it shows that these negative conclusions arise because, in each case, some of their assumptions negate other crucial assumptions. Once this is understood, not only do the conclusions become expected, but a wide class of other phenomena can also be anticipated. (shrink)

Purpose This paper explores and identifies customer-value-related sacrifices that consumers attach to interactive health/life insurance. This paper aims to increase understanding of why individual consumers are not willing to embrace behaviour-tracking-based insurance applications. Design/methodology/approach The authors analysed data from a qualitative survey of Finnish insurance consumers who were not keen on adopting interactive insurance products. Findings Developed through thematic analysis, the framework presented in this paper illustrates consumers’ value sacrifices on four dimensions: economic, functional, emotional and symbolic value. Research limitations/implications (...) The framework and insights emerging in the study hold several implications related to increased understanding of consumers’ perceptions of insurance and to developing interactive insurance services. In addition, this work provides a promising foundation and avenues for further considerations related to digital ethics in insurance. Originality/value To the best of the authors’ knowledge, this paper is the first piece applying a value sacrifice perspective in studying consumers’ unwillingness to adopt interactive insurance products.

Consciousness seems to be an enigmatic phenomenon: it is difficult to imagine how our perceptions of the world and our inner thoughts, sensations and feelings could be related to the immensely complicated biological organ we call the brain. This volume presents the thoughts of some of the leading philosophers and cognitive scientists who have recently participated in the discussion of the status of consciousness in science. The focus of inquiry is the question: "Is it possible to incorporate consciousness into science?" (...) Philosophers have suggested different alternatives -- some think that consciousness should be altogether eliminated from science because it is not a real phenomenon, others that consciousness is a real, higher-level physical or neurobiological phenomenon, and still others that consciousness is fundamentally mysterious and beyond the reach of science. At the same time, however, several models or theories of the role of conscious processing in the brain have been developed in the more empirical cognitive sciences. It has been suggested that non-conscious processes must be sharply separated from conscious ones, and that the necessity of this distinction is manifested in the curious behavior of certain brain-damaged patients. This book demonstrates the dialogue between philosophical and empirical points of view. The writers present alternative solutions to the brain-consciousness problem and they discuss how the unification of biological and psychological sciences could thus become feasible. Covering a large ground, this book shows how the philosophical and empirical problems are closely interconnected. From this interdisciplinary exploration emerges the conviction that consciousness can and should be a natural part of our scientific world view. (shrink)

In disputes about conceptual analysis, each side typically appeals to pre-theoretical 'intuitions' about particular cases. Recently, many naturalistically oriented philosophers have suggested that these appeals should be understood as empirical hypotheses about what people would say when presented with descriptions of situations, and have consequently conducted surveys on non-specialists. I argue that this philosophical research programme, a key branch of what is known as 'experimental philosophy', rests on mistaken assumptions about the relation between people's concepts and their linguistic behaviour. The (...) conceptual claims that philosophers make imply predictions about the folk's responses only under certain demanding, counterfactual conditions. Because of the nature of these conditions, the claims cannot be tested with methods of positivist social science. We are, however, entitled to appeal to intuitions about folk concepts in virtue of possessing implicit normative knowledge acquired through reflective participation in everyday linguistic practices.

The authors study how an aerosol technology research group constructed a research agenda for itself and how its activity was changed in the process. The group's research agenda was heterogeneous, comprising several research areas in which the knowledge of aerosols was applied in different industrial contexts. The authors analyze the development of one of these areas, the research on the production of ultrafine particles from 1992 to 1997, employing the concept of mediated activity that has been developed in the cultural-historical (...) theory of activity. In the analysis, the activity is seen as the coevolution of the subject, the means, and the research object and the networks of collaboration with other activities. The applications developed in the collaborative networks significantly influence the identity and learning of the researchers, the construction of tools and instruments, and the selection of the phenomena to be studied.

In this paper I develop the thesis that dreams are essential to an understanding of waking consciousness. In the first part I argue in opposition to the philosophers Malcolm and Dennett that empirical evidence now shows dreams to be real conscious experiences. In the second part, three questions concerning consciousness research are addressed. (1) How do we isolate the system to be explained (consciousness) from other systems? (2) How do we describe the system thus isolated? (3) How do we reveal (...) the mechanisms on which this system is based? I suggest that empirical dream research combined with other empirical approaches can help us to sketch answers to all of these questions. I argue that the subjective form of dreams reveals the subjective, macro-level form of consciousness in general and that both dreams and the everyday phenomenal world may be thought of as constructed “virtual realities”. A major task for empirical consciousness research is to find out the mechanisms which bind this experienced world into a coherent whole. (shrink)

In this article we investigate the family of independence-friendly (IF) logics in the equality-free setting, concentrating on questions related to expressive power. Various natural equality-free fragments of logics in this family translate into existential second-order logic with prenex quantification of function symbols only and with the first-order parts of formulae equality-free. We study this fragment of existential second-order logic. Our principal technical result is that over finite models with a vocabulary consisting of unary relation symbols only, this fragment of second-order (...) logic is weaker in expressive power than first-order logic (with equality). Results about the fragment could turn out useful for example in the study of independence-friendly modal logics. In addition to proving results of a technical nature, we address issues related to a perspective from which IF logic is regarded as a specification framework for games, and also discuss the general significance of understanding fragments of second-order logic in investigations related to non-classical logics.

R. G. Collingwood's re-enactment doctrine has been widely discussed in recent years by his commentators. However, most philosophers who discuss the re-enactment doctrine touch only briefly on his view of the identity of thoughts. This is surprising because Collingwood claims that the historian's successful re-enactment of the thought behind the historical agent's action involves re-thinking the same thought as the agent and not merely a copy of his thought.

Truth-relativism is the claim that the truth of statements is dependent on the context in which they are made. In this article, truth-relativism is considered as a way to explain disagreements. Viewpoint relativism, a recent version of truth-relativism, is introduced as a useful framework to analyse how truth-relativism approaches disagreements. Viewpoint relativism is based on contextual semantics and the logic of viewpoint, which is a two-dimensional modal logic. In viewpoint relativism, the central concept is a point of view in relation (...) to which truth claims are evaluated. Viewpoint relativism is compared to the truth-relativism of Peter Lasersohn and John MacFarlane. Finally, truth-relativism is defended against the critique of Paul Boghossian that it represents untenable ‘replacement relativism’. (shrink)

Points of view are a central phenomenon in human cognition. Although the concept of point of view is ambiguous, there exist common elements in different notions. A point of view is a certain way to look at things around us. In conceptual points of view, things are looked at or interpreted through conceptual lenses. Conceptual points of view are important for epistemology, cognitive science, and philosophy of science. In this article, a new method to formalize conceptual points of view is (...) introduced. It is based on the conceptual space approach, where concepts are regions of multi-dimensional quality spaces. Points of view, as defined in this article, consist of a selection of relevant dimensions, referred to here as determinables, and of a certain supposition, referred to here as a theory, about the subject content. After considering some early efforts to formalize points of view, the notion of conceptual space is defined and explored. One concept of point of view is defined and developed in the framework of conceptual space, and a new logic for points of view is also outlined. The problem of mind–body correlation is discussed as an example of the application of the notion of points of view. To conclude, the meaning and applications of the new concepts and tools developed in the article are discussed. (shrink)

Several theories claim that dreaming is a random by-product of REM sleep physiology and that it does not serve any natural function. Phenomenal dream content, however, is not as disorganized as such views imply. The form and content of dreams is not random but organized and selective: during dreaming, the brain constructs a complex model of the world in which certain types of elements, when compared to waking life, are underrepresented whereas others are over represented. Furthermore, dream content is consistently (...) and powerfully modulated by certain types of waking experiences. On the basis of this evidence, I put forward the hypothesis that the biological function of dreaming is to simulate threatening events, and to rehearse threat perception and threat avoidance. To evaluate this hypothesis, we need to consider the original evolutionary context of dreaming and the possible traces it has left in the dream content of the present human population. In the ancestral environment human life was short and full of threats. Any behavioral advantage in dealing with highly dangerous events would have increased the probability of reproductive success. A dream-production mechanism that tends to select threatening waking events and simulate them over and over again in various combinations would have been valuable for the development and maintenance of threat-avoidance skills. Empirical evidence from normative dream content, children's dreams, recurrent dreams, nightmares, post traumatic dreams, and the dreams of hunter-gatherers indicates that our dream-production mechanisms are in fact specialized in the simulation of threatening events, and thus provides support to the threat simulation hypothesis of the function of dreaming. Key Words: dream content; dream function; evolution of consciousness; evolutionary psychology; fear; implicit learning; nightmares; rehearsal; REM; sleep; threat perception. (shrink)
