There is a widespread belief in the academic world—above all in the United States and in the scientific communities around the world accepting U.S. mainstream science as their standard —that »schools« have lost their grounds and their legitimacy in psychology and other sciences.»Schools of thought« are seen as hampering freedom of thought and research, progress in science would have a better chance when free of such affiliations, and »objectivity« in science is seen to be best granted by some sort of (...) disinterested eclecticism.If you agree with such a premise, it is clear that it would not make much sense to run an international scientific society like the GTA, which explicitly feels committed to such a »school«. I am not the first one to object to such a view, more meritorious people have done so before me. (shrink)

Summary Giancarlo Trombini presents the continuation of his research on the question of which criteria can be used to assess the progress of therapy in an objectively verifiable way and to make the decision on the completion of therapy. In the first phase of his research, the phenomenological criterion of a qualitative change in the patient’s relations toward the positive and higher complexity was proposed for this purpose. In terms of the working method in analytic therapy, this meant concretely: attention (...) should be paid to what development is shown in the comparison of the relationships that occur in the dream narrative and in the subsequent associations. This criterion was therefore given the name manifest dream/association comparison (MDAC)—comparison between the manifest dream and the subsequent associations. The idea can easily be transferred to those therapy methods, which do not primarily work with reports of dream memories and subsequent associations—also, in other ways of working, it is possible to pay attention, in the way suggested by Trombini, to the qualitative development of the relationships which are thematized by the clients in the course of an hour. To this first criterion, another phenomenological criterion is now added in the present article: that of the “concluding therapeutic turn” (CTT). If the patient’s development reaches this turn in the course of the therapy in one session, this indicates, according to Trombini, that the therapy can soon be concluded. The fulfillment of this criterion can be recognized by the fact that in the sequence of dream narration and subsequent associations in a session, a relational dynamic toward the positive and higher complexity becomes recognizable and that is, at the same time, connected with a reconciliation of the three temporal reference systems (past, present, and future). The achievement of this CTT indicates that the patient is aware of the changes made in therapy and makes it evident to the therapist that the therapy is nearing completion. (shrink)

In this essay, I will explain why Methodological Naturalism (MN) fails as a demarcating criteria for science. I will argue that MN is not precise enough to be useful for demarcation, unable to follow the evidence where it leads, not theologically neutral (despite its stated goals as such), and difficult to justify (and currently unjustified) as an ontological or epistemic principle.

The article outlines the Multiple-Field-Approach ("Mehr-Felder-Ansatz") in Gestalt Theoretical Psychotherapy and in psychotherapy in general. This Gestalt theory based approach deals 1) with the conditions under which a secondary phenomenal field (containing a secondary phenomenal ego and a secondary phenomenal environment) segregates within the primary phenomenal field, 2) with the dynamic field interaction between primary and secondary field and their role in psychotherapy, 3) with psychotherapeutic techniques favouring the segregation and favouring the dissolution of a secondary field . Some of (...) these phenomena have been discussed as mind-wandering, daydreaming, or - in a pathological context - as dissociation. But it seems that the Gestalt psychological approach presented in this paper has to offer a more promising framework for these phenomena and their dynamics. (shrink)

Systems of logico-probabilistic (LP) reasoning characterize inference from conditional assertions interpreted as expressing high conditional probabilities. In the present article, we investigate four prominent LP systems (namely, systems O, P, Z, and QC) by means of computer simulations. The results reported here extend our previous work in this area, and evaluate the four systems in terms of the expected utility of the dispositions to act that derive from the conclusions that the systems license. In addition to conforming to the dominant (...) paradigm for assessing the rationality of actions and decisions, our present evaluation complements our previous work, since our previous evaluation may have been too severe in its assessment of inferences to false and uninformative conclusions. In the end, our new results provide additional support for the conclusion that (of the four systems considered) inference by system Z offers the best balance of error avoidance and inferential power. Our new results also suggest that improved performance could be achieved by a modest strengthening of system Z. (shrink)

The paper presents basic Gestalt psychological concepts of ego and self. They differ from other concepts in the way that they do not comprehend ego and self as fixed entities or as central controlling instances of the psyche, but as one specific organized unit in a psychological field in dynamic interrelation with the other organized units—the environment units—of this field. On this theme, well-known representatives of Gestalt theory have presented some general and special theories since the early days of this (...) approach that could partly be substantiated experimentally. They illuminate the relationship between ego and world in everyday life as well as in the case of mental disorders. Not only the spatial extension of the phenomenal ego is subject to situational changes, but also its place in the world, its functional fitting in this world, its internal differentiation, its permeability to the environment, and much more. The German Gestalt psychologist Wolfgang Metzger emphasizes the significant functional role that this dynamic plasticity of the phenomenal world and its continuously changing segregation of ego and environment have for human life by designating the phenomenal world as a “Central Steering Mechanism.” In this article, ego and self as part of this field in their interrelation with the total psychological field will be illuminated from the perspective of the thinking of the Gestalt psychologists Max Wertheimer, Kurt Koffka, Wolfgang Köhler, Kurt Lewin, Wolfgang Metzger, Mary Henle, Edwin Rausch, and Giuseppe Galli.

Summary In 1915 the Danish psychologist Edgar Rubin describes in his famous work on figure-ground perception, the phenomenon that when you look attentively at a picture, a second, virtual ego arises, breaking away from the viewer-ego to wander around in the picture along the contours of the depicted. In 1982, German Gestalt psychologist Edwin Rausch expanded this observation of the emergence of a second phenomenal ego to the conclusion that not only does a second phenomenal ego emerge, but with it (...) a second phenomenal total field, ie a second phenomenal world with its own phenomenal ego and an own phenomenal environment of this ego. Several years ago, I proposed a multi-field-approach in psychotherapy building on this research. This approach involves three levels: First, the level of phenomenological observation and psychological analysis of the conditions that determine the formation of such a second total field (and even further total fields), regardless of whether this occurs spontaneously or intentionally or as a result of external influences. Second, the level of explanation of various psychic processes, which in the field of psychotherapy have been explained so far mainly on the basis of depth psychology, and the conceptualization of the therapeutic situation and therapeutic processes from a Gestalt psychological perspective. Third, finally, the level of practical application of such insights on the development of appropriate procedures and interventions that can promote or defer the emergence of such second or multiple fields in psychotherapy. The present article introduces the multi-field approach, especially at the first level, and refers to research and discussion on mind wandering, imagining, daydreaming and dissociation. (shrink)

Summary The article substantiates the possibility and meaningfulness of a coherent theoretical system for psychotherapy, as it is strived for in Gestalt Theoretical Psychotherapy and presented in several articles in this issue of the journal "Gestalt Theory". The necessity of consistency in the theoretical assumptions and concepts of a psychotherapy method is not derived from scientific considerations alone, but already arises from the elementary role of consistency in human life. This also results in the requirements for the consistency of theoretical (...) foundations of psychotherapy. It is not fulfilled in a mere internal, logical consistency of its models, but only in the actual fitting together with the critical-phenomenal and naive-phenomenal worlds of the therapists and their clients in the reality test of life.

Pakṣilasvāmin's introduction to his Nyāyabhāṣyam is perhaps one of the most interesting texts of the older Nyāya indispensable to the understanding of the system. This is not because the ideas expressed therein were not to be surpassed at a later period, but because in it the development of the school appears fixed, as it were, in a "transitory moment" (transitorisches Moment), and we see there for the first time that line of thought, which historically took form in the Nyāya philosophy, (...) becoming aware of itself in a clear, though archaic, manner. Furthermore, if we bear in mind to what extent such an interpretation of a school (given by itself) determines its development, the importance of Pakṣilasvāmin's text for the history of Nyāya cannot be over-estimated.

La théorie de l’organisme social était une approche foncièrement et largement répandue au début du 20ème siècle, qui était acceptée par de nombreuses orientations théoriques dans la sociologie et l’économie. L’approche de Rudolf Steiner s’y rapportant est bien connue. La théorie de Gerhard Stolzmann ne l’est pas autant. Ce dernier était un représentant de ce qu’on appelle le « mouvement des droits sociaux de l’économie politique » et au plan philosophique, il défendait le néo-kantisme (école de Marburg, de l’Allemagne (...) du sud-ouest). Stolzmann a connu et cité les écrits de Steiner sur l’organisme social, comme on peut le prouver. Dans cet essai, on va mettre au jour les communautés et tendances dans le concept de l’organisme social chez Stolzmann et Steiner. Tous deux ont mis en exergue l’importance du spirituel et en conséquence de la sphère du droit, pour la société et l’économie dans leur théorie. Mais Steiner eut essentiellement une amorce plus pratique. Son concept d’organisme social est plus une proposition de réforme pour l’économie et la société, alors que Stolzmann fait ressortir la signification théorique générale toujours valable de sa théorie.

In this paper, I give a brief overview of ideas from Reformed Epistemology, and the relationship between faith, evidence, and belief. I discuss what makes belief in God rationally warranted, and how reformed epistemology strikes a middle ground between fideism and evidentialism. In effect, reformed epistemology avoids the fideist idea that belief in God must be taken on "blind faith," but also avoids some of the epistemic issues present in evidentialism, such as its self-referential incoherence. The reformed epistemologist says belief (...) in God is rational, but not for the reasons demanded by evidentialists. (shrink)

Climate change and other harmful large-scale processes challenge our understandings of individual responsibility. People throughout the world suffer harms—severe shortfalls in health, civic status, or standard of living relative to the vital needs of human beings—as a result of physical processes to which many people appear to contribute. Climate change, polluted air and water, and the erosion of grasslands, for example, occur because a great many people emit carbon and pollutants, build excessively, enable their flocks to overgraze, or otherwise stress (...) the environment. If a much smaller number of people engaged in these types of conduct, the harms in question would not occur, or would be substantially lessened. However, the conduct of any particular person (and, in the case of climate change, of even quite large numbers of people) could make no apparent difference to their occurrence. My carbon emissions (and quite possibly the carbon emissions of much larger groups of people dispersed throughout the world) may not make a difference to what happens to anyone. When the conduct of some agent does not make any apparent difference to the occurrence of harm, but this conduct is of a type that brings about harm because many people engage in it, we can call this agent an overdeterminer of that harm, and their conduct overdetermining conduct. In this essay we explore the moral status of overdetermining harm. (shrink)

Research on Sebastian Franck (1499 – 1543) has so far mainly focused on the topics “Sebastian Franck as a historian” or “Sebastian Franck as a critic of theology,” while Gnosticism in the philosophy of the radical reformer has received less attention. Since the beginning of the new millennium, the interest in a certain movement of Gnosticism, namely Hermeticism, has increased however. This paper examines the question of the parallels in content between Gnostic representatives such as the Carpocratians, the Ebionites, and (...) Sebastian Franck. Irenaeus of Lyon is used as a source for the Carpocratians and the Ebionites. Substantial similarities can be found in the fragmentary reports of Irenaeus on the Carpocratians and Ebionites and the teachings of Franck. The parallels between the Carpocratians and Franck can be identified in the concept of the Divine, the tripartite nature of the soul, and the doctrine of salvation. Unlike orthodox Christianity, both Franck and the Carpocratians believed in the self-salvation of people from their sins. Through the discovery of their spirit, all people can access the abilities that Yeshua had in his incarnation. The rejection of both the doctrine of original sin and the doctrine of grace is what Franck has in common with the Ebionites. However, the doctrine of grace would not make any sense for the Carpocratians either, as, according to their conviction, the soul is redeemed by the enlightenment of the spirit. (shrink)

Dieser Aufsatz beschäftigt sich mit der These von Frances Yates, dass Denker wie Giordano Bruno und Agrippa von Nettesheim angenommen haben, dass die Schriften des Hermes Trismegistos von dem Ägypter Thoth (Hermes) stammten. Es soll in diesem Aufsatz demonstriert werden, dass die Annahme von Yates sehr spekulativ war und zumindest nicht auf Agrippa zutrifft, da aus keiner seiner Schriften hervorgeht, dass er das Corpus Hermeticum für Texte des Ägypters Hermes selbst hielt. Er glaubte zwar an die Legende des Hermes, aber (...) in dieser Abhandlung wird die Hypothese überprüft, dass Agrippa dem Neuplatoniker Jamblichus folgte, dass griechische Philosophen, die ungefähr in der Zeit von Jamblichus lebten, diese Schriften verfasst haben. Damit wäre die Hypothese von Frances Yates widerlegt, nach der Agrippa glaubte, das Corpus Hermeticum würde direkt vom Ägypter Thoth herrühren. Aus der „Occulta philosophia“ geht hervor, dass Agrippa die Werke Jamblichus hervorragend kannte, doch Yates hielt es scheinbar für nicht relevant, dass Jamblichus darauf hingewiesen hatte, dass das Corpus Hermeticum von ägyptischen Priestern geschrieben wurden. Es war damit nicht Casaubon, der als Erster erkannt hat, dass das Corpus Hermeticum unmöglich auf eine ägyptische Legende mit dem Namen Hermes zurückgehen konnte. Casaubon dachte selbst nicht, dass er der Erste war, der den Irrtum aufdeckte, denn er berichtete ebenfalls von der Aussage von Jamblichus. (shrink)

Crises in therapist-patient relationship can also become a challenge in clinical supervision. However, success and failure in establishing and maintaining constructive relationships in therapy and supervision is not only subject to a lucky fit of personal characteristics (therapist A gets along well/badly with client B; supervisee A gets along well/badly with supervisor C). Rather, we can identify determining field conditions in the overall therapeutic and supervisory situation for this outcome. We do not only focus on the persons involved, but also (...) on their environment, the task to be accomplished together, further framework conditions and the power relations resulting from their mutual influence-in the supervised case of therapy as well as in supervision itself. We want to examine the structure and dynamics of these relationships from a genuine Gestalt psychological perspective. What contributes to a cooperative atmosphere? When do goals get out of sight? What can make the atmosphere hostile? How do such developments become accessible in supervision? (shrink)

Meta-induction, in its various forms, is an imitative prediction method, where the prediction methods and the predictions of other agents are imitated to the extent that those methods or agents have proven successful in the past. In past work, Schurz demonstrated the optimality of meta-induction as a method for predicting unknown events and quantities. However, much recent discussion, along with formal and empirical work, on the Wisdom of Crowds has extolled the virtue of diverse and independent judgment as essential to (...) maintenance of 'wise crowds'. This suggests that meta-inductive prediction methods could undermine the wisdom of the crowd inasmuch these methods recommend that agents imitate the predictions of other agents. In this article, we evaluate meta-inductive methods with a focus on the impact on a group's performance that may result from including meta-inductivists among its members. In addition to considering cases of global accessibility (i.e., cases where the judgments of all members of the group are available to all of the group's members), we consider cases where agents only have access to the judgments of other agents within their own local neighborhoods.

In this essay we argue that an agent’s failure to assist someone in need at one time can change the cost she can be morally required to take on to assist that same person at a later time. In particular, we show that the cost the agent can subsequently be required to take on to help the person in need can increase quite significantly, and can be enforced through the proportionate use of force. We explore the implications of this argument (...) for the duties of the affluent to address global poverty. (shrink)

It is argued that logic, and in particular mathematical logic, should play a key role in the undergraduate curriculum for students in the computing fields, which include electrical engineering (EE), computer engineering (CE), and computer science (CS). This is based on 1) the history of the field of computing and its close ties with logic, 2) empirical results showing that students with better logical thinking skills perform better in tasks such as programming and mathematics, and 3) the skills students are (...) expected to have in the job market. Further, the authors believe teaching logic to students explicitly will improve student retention, especially involving underrepresented minorities. Though this work focuses specifically on the computing fields, these results demonstrate the importance of logic education to STEM (science, technology, engineering, and mathematics) as a whole.

The problem of evil is one of the most significant challenges to theism and Christianity in particular, asking why there seems to be so much evil if an omnibenevolent (all good), loving God exists. The problem of evil, as posed by many atheists and agnostics today, (following Epicurus) often asserts that the following premises cannot all be true: 1. God exists, and is omnipotent (all-powerful) 2. God exists, and is omnibenevolent (all-good) 3. God exists, and is omniscient (all-knowing) 4. Evil (...) exists Christian thinkers over the past two thousand years have given various responses to the problem of evil in the form of various theodicies, or attempts to explain why evil exists (or appears to exist) given the existence of an Omniscient, Omnipotent, Omnibenevolent God. This document serves as a brief overview of different theodicies offered by Christian thinkers throughout history. (shrink)

Der menschliche Verstand, sagt Kant, „kann nur d e n k e n und muss in den Sinnen die Anschauung suchen“ [KrV, §16]. Da der Verstand nur denken kann, ist denken und Anschauung suchen nicht zweierlei. Denn auch die Anschauung suchen muss man können. Daher sieht Kant das Besondere „unseres discursiven, der Bilder bedürftigen Verstandes (intellectus ectypus )“ [KdU §77] im „Vermögen, den Gegenstand sinnlicher Anschauung zu denken“ [KrV B75/A51]. Daher ist Verstand primär ein Erkenntnisvermögen. Denn ohne „den Stoff zum (...) Denken“ aus empirischer Anschauung „würde der Actus, Ich denke, doch nicht stattfinden“ [B423], und indem er sucht, findet er (cum quaerit, invenit): „Ich, der ich denke und anschaue, ist die Person“ [Preisschrift]. In diesem Aufsatz werden in einem ersten Ausblick einige grundlegende Textstellen auf dieser Basis analysiert. -/- Short summary: What is it like to be human understanding, according to Kant? Understanding is in search of intuition (intellectus ectypus quaerens sensibilitatem), and happens to be pretty successful, at least everywhere and anytime.

These three volumes, entitled Essays On Values, bring together fortyone recent articles by researchers at the Nova Institute of Philosophy (IFILNOVA). They are a small sample of everything that, in the last four years, the Institute’s researchers have published, in English, in indexed journals and collections of essays with peer review. As a whole, they reflect very well the research work that is done at IFILNOVA. Section I. of Volume 1 gathers six articles that deal directly with the question “what (...) are values?”, the question that guides all the work of the institute’s different laboratories and research groups. The first article, by Susana Cadilha and Vítor Guerreiro, results from work developed in the Laboratory of Ethics and Political Philosophy (EPLab); the second, by João Constâncio, from the Lisbon Nietzsche Group; the third, by Alexandra Dias Fortes, from the Lisbon Wittgenstein Group; the third and fifth, by Nuno Fonseca, and Maria Filomena Molder, from the Aesthetics and Philosophy of Art Group of the Laboratory of Culture and Value (CultureLab); the last, by Erich H. Rast, from the Philosophy of Language and Argumentation Theory Group and the Lisbon Mind, Cognition & Knowledge Group of the Laboratory of Argumentation, Cognition, and Language (ArgLab). Section II. brings together three articles by members of the Lisbon Nietzsche Group. Since 2010, the Lisbon Nietzsche Group has completed several funded projects, and has established itself as a leading international research group on Nietzsche’s thought. The three articles demonstrate the crucial importance of the question of values in Nietzsche’s work, always thought from the perspective of the possibility of a “transvaluation of all values”. Maria João Mayer Branco’s article focuses on the value of introspection, and how Nietzsche anticipates Wittgenstein’s “expressivist” view of the “the Peculiar Grammar of the Word ‘I’” and the impossibility of private languages. Marta Faustino’s article considers the theme of affirmation and the value of life through the interpretation of Nietzsche’s reflection on truthfulness, intellectual honesty and courage in the light of Michel Foucault’s work on parrhesia. Pietro Gori’s article studies how Nietzsche creates a new anthropological ideal based on his enquiry into the values of the “good European”. The area of Wittgenstein studies has had a strong influence on the institute since the time when it was a philosophy of language institute. The Wittgensteinian distinction between facts and values was decisive in defining the question of values as the central issue of IFILNOVA’s research project, replacing the focus on philosophy of language. More recently, the focus of research at the Lisbon Wittgenstein Group has been on epistemic values, in particular in their connection with the question of religious belief. In Section III., Nuno Venturinha’s article examines, in the light of an epistemological standpoint, the way Wittgenstein thinks about the possibility of translation. Robert Vinten’s article argues that Wittgenstein’s thought contains elements for a critique of the concept of justice and of the liberal political visions of both Richard Rorty and Chantal Mouffe, despite the fact that both have drawn inspiration from Wittgenstein. Benedetta Zavatta’s article questions the value of mythology by thinking of it as a disease of language – not only in Wittgenstein, but also in a whole philosophical tradition that preceded him. The existence of a research group in ancient philosophy is a recent but very promising development in the life of IFILNOVA. Section IV. includes two articles by members of the group. Paulo Alexandre Lima’s article considers the critique of misology and the value of discourse in Plato’s Phaedo. Hélder Telo’s article examines the pedagogical and protreptic value of imperfection in Plato’s work. (shrink)

In recent years it has often been claimed that policies such as subsidies paid to domestic producers by affluent countries and tariffs on goods produced by foreign producers in poorer countries violate important moral requirements because they do severe harm to poor people, even kill them. Such claims involve an empirical aspect—such policies are on balance very bad for the global poor—and a philosophical aspect—that the causal influence of these policies can fairly be characterized as doing severe harm and killing. (...) In this essay, we examine the philosophical aspect of this issue. We conclude that these policies do not do harm to the poor, but rather enable harm to them in various ways, and explore the moral implications of this fact. (shrink)

Frequency-based arguments against rational belief in a miracle occurring have been present for centuries, the most notable being from David Hume. In this essay, the authors show Hume's argument rests on an equivocation of probability, with him using the term interchangeably to refer to two different and incompatible perspectives: Bayesianism and Frequentism. Additionally, the authors show that any frequentist arguments against miracles relies on a view of probability that is only dubiously linked to rationality. In other words, the frequentist cannot (...) have it both ways: if probability is indeed frequency, then miracles are indeed improbable but not necessarily irrational to believe. On the other hand, if probability is an agent's confidence in a given belief, than under certain assumptions miracles are indeed highly probable and thus rational to believe despite their rarity. As a result, regardless of which view of probability one takes, it does not follow that believing in a miracle is irrational simply because miracles are rare. (shrink)

We investigate a lattice of conditional logics described by a Kripke type semantics, which was suggested by Chellas and Segerberg – Chellas–Segerberg (CS) semantics – plus 30 further principles. We (i) present a non-trivial frame-based completeness result, (ii) a translation procedure which gives one corresponding trivial frame conditions for arbitrary formula schemata, and (iii) non-trivial frame conditions in CS semantics which correspond to the 30 principles.

Linear Algebra is an extremely important field that extends everyday concepts about geometry and algebra into higher spaces. This text serves as a gentle motivating introduction to the principles (and philosophy) behind linear algebra. This is aimed at undergraduate students taking a linear algebra class - in particular engineering students who are expected to understand and use linear algebra to build and design things, however it may also prove helpful for philosophy majors and anyone else interested in the ideas behind (...) linear algebra. Linear algebra is used extensively in statistics, mechanical engineering, circuit theory, signal processing, economics and data science/machine learning. I have found in my teaching career that students tend to struggle the most with motivating the "why" behind the abstract concepts discussed in linear algebra. This can be difficult for professors to understand because we are so used to using the language of linear algebra we take for granted why these questions are important in the first place. In other words, we may understand the “why” (after years of using these tools), but our students may not. This text seeks to explain this “why” in an accessible, engaging way. (shrink)

In this paper we discuss the new Tweety puzzle. The original Tweety puzzle was addressed by approaches in non-monotonic logic, which aim to adequately represent the Tweety case, namely that Tweety is a penguin and, thus, an exceptional bird, which cannot fly, although in general birds can fly. The new Tweety puzzle is intended as a challenge for probabilistic theories of epistemic states. In the first part of the paper we argue against monistic Bayesians, who assume that epistemic states can (...) at any given time be adequately described by a single subjective probability function. We show that monistic Bayesians cannot provide an adequate solution to the new Tweety puzzle, because this requires one to refer to a frequency-based probability function. We conclude that monistic Bayesianism cannot be a fully adequate theory of epistemic states. In the second part we describe an empirical study, which provides support for the thesis that monistic Bayesianism is also inadequate as a descriptive theory of cognitive states. In the final part of the paper we criticize Bayesian approaches in cognitive science, insofar as their monistic tendency cannot adequately address the new Tweety puzzle. We, further, argue against monistic Bayesianism in cognitive science by means of a case study. In this case study we show that Oaksford and Chater’s (2007, 2008) model of conditional inference—contrary to the authors’ theoretical position—has to refer also to a frequency-based probability function.

In this article, I define a cultural epistemology as a set of socially reinforced assumptions about how knowledge and truth are produced. Unlike a philosophical epistemology, a cultural epistemology is largely the product of culture and largely invisible. As products of culture, cultural epistemology are relatively unquestioned and, in many cases, philosophically unsophisticated. There are three common types of cultural epistemologies, influenced by who holds power in a given society: an epistemological monarchy, an epistemological oligarchy and an epistemological democracy. A (...) given cultural epistemology subsequently influences the legitimacy of culture and government itself. I argue argue that Americans tend to hold an "epistemological democracy" with two distinct facets: a trust in consensus, linked to living in a democratic republic, and a trust in their own self-interest, linked to market economics and capitalism more generally. These two facets combine, interact, and even oppose each other to legitimize and challenge American culture and its political and economic systems. (shrink)

In previous work, we studied four well known systems of qualitative probabilistic inference, and presented data from computer simulations in an attempt to illustrate the performance of the systems. These simulations evaluated the four systems in terms of their tendency to license inference to accurate and informative conclusions, given incomplete information about a randomly selected probability distribution. In our earlier work, the procedure used in generating the unknown probability distribution (representing the true stochastic state of the world) tended to yield (...) probability distributions with moderately high entropy levels. In the present article, we present data charting the performance of the four systems when reasoning in environments of various entropy levels. The results illustrate variations in the performance of the respective reasoning systems that derive from the entropy of the environment, and allow for a more inclusive assessment of the reliability and robustness of the four systems.

We describe a prediction method called "Attractivity Weighting" (AW). In the case of cue-based paired comparison tasks, AW's prediction is based on a weighted average of the cue values of the most successful cues. In many situations, AW's prediction is based on the cue value of the most successful cue, resulting in behavior similar to Take-the-Best (TTB). Unlike TTB, AW has a desirable characteristic called "access optimality": Its long-run success is guaranteed to be at least as great as the most (...) successful cue. While access optimality is a desirable characteristic, concerns may be raised about the short-term performance of AW. To evaluate such concerns, we here present a study of AW's short-term performance. The results suggest that there is little reason to worry about the short-run performance of AW. Our study also shows that, in random sequences of paired comparison tasks, the behavior of AW and TTB is nearly indiscernible. (shrink)

In this paper, I wish to criticize the notion that consensus is an epistemology. While I have never seen it explicitly claimed that “consensus is an epistemology,” I have nonetheless seen it implied in many scholarly (and layperson) articles. This occurs whenever articles cite, “a majority of scholars agree that…” or “most scientists/researchers think…” In our democratic, individualistic society, we put a value on high value votes and the quantification of majority viewpoints, whether it be in political polls (due to (...) living in a democracy), online on websites with ranking or voting systems such as Reddit, YouTube, or Instagram. The danger here is we may defer too much to the consensus view without appropriate justification. I will give several reasons why we should be skeptical of appeals to consensus (including a consensus of experts), which include its non-obvious link to ontology, the fact that consensus changes, and a lack of specificity of who counts as an ``expert,'' the lack of specificity on how to handle consensus (if it does occur), and epistemic undercutting defeaters from evolutionary epistemology. While an appeal to consensus may not tell us much about whether a theory is true, they can give us practical or pragmatic reasons for trusting a position. (shrink)

This work deals with problems involving infinities and infinitesimals. It explores the ideas behind zero, its relationship to ontological nothingness, finititude (such as finite numbers and quantities), and the infinite. The idea of infinity and zero are closely related, despite what many perceive as an intuitive inverse relationship. The symbol 0 generally refers to nothingness, whereas the symbol infinity refers to ``so much'' that it cannot be quantified or captured. The notion of finititude rests somewhere between complete nothingness and something (...) having no end. -/- My concern is that many of the philosophers arguing for or against the ontology (or possibility) of an actual infinite set are unaware or unfamiliar with the mathematical literature attempting to clearly and rigorously define these terms. I believe it is a mistake to leave mathematicians out of this conversation, as analysts in particular have defined (and used) infinity in a way that is relevant to the ongoing debate between philosophers. -/- For this paper, I have selected examples from Principles of Analysis by Walter Rudin, which has become a standard text for Real Analysis classes taken by pure mathematicians and engineers. I will also restrict the scope of examples to Euclidean spaces for simplicity. Finally, I will be using addition, + and multiplication * in their usual way. (shrink)

Indigenous and non-indigenous communities in Latin America make land claims and support them with a variety of arguments. Some, such as Zapatistas and the Mapuche, have appealed to the “ancestral” or “historical” connections between specific communities and the land. Other groups, such as MST in Brazil, have appealed to the extremely unequal distribution of the land and the effects of this on the poor; the land in this case is seen mainly as a means for securing a decent standard of (...) living for members of disadvantaged groups. Although there is a large literature on the history as well as the social and political dimensions of land contestations and conflicts in Latin America, the question of whether the land claims put forward by disadvantaged groups can be morally justified has not been adequately examined. In this essay, we investigate the scope and limits of appeals to what we shall call assistance-based, contribution-based, and benefitting-based moral reasons with respect to land claims made by these disadvantaged groups.

Remittances are private financial transfers from migrant workers back to their countries of origin. These are typically intra-household transfers from members of a family who have emigrated to those who have remained behind. The scale of such transfers throughout the world is very large, reaching $338 billion U.S. in 20081—several times the size of overseas development assistance (ODA) and larger even than foreign direct investment (FDI). The data on migration and remittances is too poor to warrant very firm conclusions about (...) their effects—actual or potential—on poverty and development in poorer countries. We will however, present reasons that make it plausible to believe that remittances can contribute to poverty-reduction and promote development in poorer countries. Our main aim, however, is not to engage in detail with empirical debates about the effects of these transfers, but to establish moral grounds for favorable tax treatment on remittances on the assumption that they do have positive effects on receiving countries.

For years, the European world saw millions of swans, and all of them without exception were white. If inductive reasoning is valid, one may conclude that all swans are white. However, this would be incorrect: in 1667 Dutch explorer Willem de Vlamingh observed black swans in Australia, falsifying the hypothesis that all swans are white. While often used as a cautionary tale for the use of induction, such as with Popper’s falsification principle, I want to explore a slightly different idea: (...) does the existence of fabricated or otherwise failed accounts of Black swans give me a reason to ignore future arguments or doubt their existence? I argue that while faulty or fabricated reports do not give us a logical reason to reject a claim, they can give us a practical one for refusing to consider future arguments. This practical vs logical distinction gives an inductive reason for believing that future arguments will be invalid, but keeps one from being able to necessarily deny the claim in question without further argumentation.

Western, secularized capitalism appraises the “worth” of a worker through a wage, a numerical value assumed to reflect the value of one’s time (in the case of hourly jobs) or contribution (in the case of salary or commision-based work). Computers and AI models are capable of matching and even exceeding human performance on a variety of tasks such as mathematical computation, handwritten digit recognition, and even complex tasks such as playing the game Go. Furthermore, they can work around the clock (...) with no need for sleep, healthcare, or even a salary. As a result, computers are more “valuable” than humans under capitalism because they are more productive (in terms of quantity and, in many cases, quality of work). Combined with an erosion of the religious idea of explicit human worth or dignity, other humans are seen as mere means to the ends of those powerful enough to exploit them. Any hope of reducing inequality or promoting justice must come from an explicit belief in the “value” of human life independent of his or her ability to produce. (shrink)

Upon separation of the protein from the nucleic acid component of tobacco mosaic virus by phenol, using a fast and gentle procedure, the nucleic acid is infective in assays on tobacco leaves. A series of qualitative and quantitative control experiments demonstrates that the biological activity cannot depend on residual proteins in the preparation, but is a property of isolated nucleic acid which is thus the genetic material of the virus.

This book serves as an introduction to mathematical logic for STEM (Science, Technology, Engineering, and Mathematics) students, written for undergraduates (in particular, 1st and 2nd year undergraduates). A focus on this book is on logical thinking, not simply rote memorization, with a focus on examples and analogies relevant to students aimed at becoming technical leaders and problem solvers. This book includes propositional logic, set theory, functions and relations, and more, with coding examples provided in the Python programming language.

This contribution provides a transcription and translation of, and a commentary on, a letter of the German-Dutch-Japanese polymath Peter Hartzing to Gerhard Wolter Molanus, abbot of Loccum and famous collector of coins and medals. In the commentary, a survey of the life and intellectual endeavours of Hartzing is provided.

There are numerous formal systems that allow inference of new conditionals based on a conditional knowledge base. Many of these systems have been analysed theoretically and some have been tested against human reasoning in psychological studies, but experiments evaluating the performance of such systems are rare. In this article, we extend the experiments in [19] in order to evaluate the inferential properties of c-representations in comparison to the well-known Systems P and Z. Since it is known that System Z and (...) c-representations mainly differ in the sorts of inheritance inferences they allow, we discuss subclass inheritance and present experimental data for this type of inference in particular.

I argue that No-Ought-From-Is (in the sense that I believe it) is a relatively trivial affair. Of course, when people try to derive substantive or non-vacuous moral conclusions from non-moral premises, they are making a mistake. But No-Non-Vacuous-Ought-From-Is is meta-ethically inert. It tells us nothing about the nature of the moral concepts. It neither refutes naturalism nor supports non-cognitivism. And this is not very surprising since it is merely an instance of an updated version of the conservativeness of logic (in (...) a logically valid inference you don’t get out what you haven’t put in): so long as the expressions F are non-logical, you cannot get non-vacuous F-conclusions from non-F premises. However, the triviality of No-Non-Vacuous-Ought-From-Is is important and its non-profundity profound. No-Ought-From-Is is widely supposed to tell us something significant about the nature of the moral concepts. If, in fact, it tells us nothing, this is a point well worth shouting from the housetops. This brings me to my dispute with Gerhard Schurz who has proved a related version of No-Ought-From-Is, No-Ought-Relevant-Ought-From-Is, a proof which relaxes my assumption that ‘ought’ should not be treated as a logical constant. But if ought is not a logical expression then it does not really matter much that No-Ought-From-Is would be salvageable even if it were. Furthermore, Schurz’s proof depends on special features of the moral concepts and this might afford the basis for an abductive argument to something like non-cognitivism. As an error theorist, and therefore a cognitivist, I object. Finally I take a dim view of deontic logic. Many of its leading principles are false, bordering on the nonsensical, and even the reasonably plausible ones are subject to devastating counter-examples. (shrink)

Review of Gerhard Schurz's Philosophy of Science - A Unified Approach. Routledge, Abingdon 2014.

Was Galileo’s clash with the Church about science or about legal procedures that he had apparently neglected? Was he ultimately condemned for heresy or for violating a legal precept by publishing the "Dialogue on the Two Chief World Systems"?

A proposta é construir uma ponte de intersecção entre os pensamentos de Pareyson, Aristóteles e Platão, e, ancorando-a nos conceitos cunhados na Teoria da Formatividade, expor como o filósofo italiano relê as problemáticas colocadas pelos filósofos gregos antigos e de que maneira esta interseção de pensamentos e conceitos contribuem para a reflexão sobre Arte na atualidade e em particular para a análise da produção pictórica de Gerhard Richter.

In a recent Philosophy of Science article Gerhard Schurz proposes meta-inductivistic prediction strategies as a new approach to Hume's. This comment examines the limitations of Schurz's approach. It can be proven that the meta-inductivist approach does not work any more if the meta-inductivists have to face an infinite number of alternative predictors. With his limitation it remains doubtful whether the meta-inductivist can provide a full solution to the problem of induction.

The deep influence of affectivity on learning is now widely acknowledged (Keefer et al., 2018; Sánchez-Álvarez et al., 2021). For instance, it has been shown that affect influences key learning-relevant processes, such as motivation, perception, behavior, and critical thinking (Izard, 2002; Mayer & Salovey, 1997). Evidence also shows that emotion and mood strongly influence attention, which in turn drives learning and memory (Elbertson et al., 2010; Elias et al., 1997). Intersubjective phenomena, such as the degree of affection and respect (...) between child and teacher, also affect the child’s learning processes, academic outcomes, and brain development (Kusché & Greenberg, 2006; Ryan & Patrick, 2001). However, the relevant literature is not paying attention to increasing evidence showing that affective phenomena are rooted in interoceptive and homeostatic self- and co-regulatory processes within and between people’s living bodies (Barrett, 2017; Carvalho & Damasio, 2021; Craig, 2015, 2018; Fotopoulou et al., 2022; Fotopoulou & Tsakiris, 2017; Seth & Friston, 2016). In this theoretical chapter, we explore this connection and its importance for learning. We argue that affective experience plays a fundamental role in learning, and that affective experience is rooted in the homeostatic self-/co-regulation of living bodies. Therefore, the homeostatic self-/co-regulation of living bodies plays a fundamental role in learning. In other words, there is an intra- and interpersonal somatic dimension of learning that demands explicit consideration in educational contexts. In this way, we aim to contribute to an understanding of learning and education that moves away from an individualistic, brain-centered information-processing conception toward one centered on sentient, interdependent living bodies.

Zároveň by však tyto výzkumy neměly být (...) podřizovány historiografii, a především je v nich zapotřebí pracovat nejen s koncepty identity a sociálních svazků, ale i moci a konfliktu. (shrink)

Consider a set of shuffled observations drawn from a fixed probability distribution over some instance domain. What enables learning of inductive generalizations which proceed from such a set of observations? The scenario is worthwhile because it epistemically characterizes most of machine learning. This kind of learning from observations is also inverse and ill-posed. What reduces the non-uniqueness of its result and, thus, its problematic epistemic justification, which stems from a one-to-many relation between the observations and many learnable generalizations? The paper (...) argues that this role belongs to any complexity regularization which satisfies Norton’s Material Theory of Induction (MTI) by localizing the inductive risk to facts in the given domain. A prime example of the localization is the Lottery Ticket Hypothesis (LTH) about overparameterized neural networks. The explanation of MTI’s role in complexity regularization of neural networks is provided by analyzing the stability of Empirical Risk Minimization (ERM), an inductive rule that controls the learning process and leads to an inductive generalization on the given set of observations. In cases where ERM might become asymptotically unstable, making the justification of the generalization by uniform convergence unavailable, LTH and MTI can be used to define a local stability. A priori, overparameterized neural networks are such cases and the combination of LTH and MTI can block ERM’s trivialization caused by equalizing the strengths of its inductive support for risk minimization. We bring closer the investigation of generalization in artificial neural networks and the study of inductive inference and show the division of labor between MTI and the optimality justifications (developed by Gerhard Schurz) in machine learning.
