In Igbo traditional religion (ITR), there are different means through which therapy and healing are achieved. One such means is through the Nsukka-Igbo Ọmabe masquerade festival rituals and performance theatre. To seek out this aspect of the cultural festival that has been under-researched, this study delves into detailed discussions of the pre-arrival, arrival, events in between, departure and postdeparture of the Ọmabe masquerade festival. Relying on a qualitative method, the study analytically and descriptively discusses the data gathered through participatory observations (...) and interview sessions with some of the devotees possessing sufficient knowledge of the masquerade tradition and festival. Photographs have been included to flesh out the narratives, as well as enrich and enhance the readers’ engagement with the article. Also, relevant materials from extant literature are quoted and cited. The study examined the rituals, music, performances and other interesting key components of the festival and found that the traditional practice through masquerade festivals such as the Ọmabe is therapeutic, leading to emotional activation and healing. Undoubtedly, this has been sustaining its re-enactments in the face of neoreligious intolerance, urbanisation, modernity and globalisation that have been adversely affecting cultural practices. Contribution: The article critically engages with the reappraisal of the Ọmabe cultural heritage festival among the Nsukka-Igbo people, providing thought-provoking, impactful research as well as insightful reading towards achieving an understanding of its rituals, materiality and performance theatre and their accompanying therapy and healing benefits. Bearing in mind that HTS Teologiese Studies/Theological Studies focuses on religious issues and that the ‘masking festival’ is a part of Indigenous religious practice, the author considers this article to be suitable for its objectives.

A Reforma em território alemão possui duas figuras, por vezes próximas entre si, por vezes muito distantes: Lutero e Tomás Müntzer. À medida que foi se envolvendo na vida de seus fiéis, Müntzer foi tomando caminhos próprios, discordando de Lutero que este tomava a “Palavra, em sua realidade objetiva, como constitutiva da Igreja, e afirmando que os verdadeiros fiéis são os que possuem a experiência subjetiva do “Espírito”. Também contra Lutero, que defende a resistência à autoridade, mas em questões seculares (...) aceita a tirania, Müntzer, que vê a fé fortemente inserida no social, defende a revolução armada contra os príncipes. Müntzer não nega a graça, mas esta possui papel secundário em seu pensamento, enquanto, para Lutero, ela se coloca no centro de suas preocupações teológicas. PALAVRAS-CHAVE – Reforma. Palavra. Graça.

This study examines steroid production in fathers watching their children compete, extending previous research of vicarious success or failure on men’s hormone levels. Salivary testosterone and cortisol levels were measured in 18 fathers watching their children play in a soccer tournament. Participants completed a survey about the game and provided demographic information. Fathers with higher pregame testosterone levels were more likely to report that referees were biased against their children’s teams, and pre- to postgame testosterone elevation was predicted by watching (...) sons compete rather than daughters as well as perceptions of unfair officiating. Pregame cortisol was not associated with pregame testosterone or with perceived officiating bias, but cortisol did fluctuate synergistically with testosterone during spectator competition. Although fathers showed no consistent testosterone change in response to winning or losing, pregame testosterone may mediate steroid hormone reactivity to other aspects of their children’s competition.

Eric Martin and Daniel N. Osherson present a theory of inductive logic built on model theory. Their aim is to extend the mathematics of Formal Learning Theory to a more general setting and to provide a more accurate image of empirical inquiry. The formal results of their study illuminate aspects of scientific inquiry that are not covered by the commonly applied Bayesian approach.

A corrected and extensively annotated version of the sole meeting between two of the most important figures in twentieth-century intellectual life.

The paper is a study of the logic of existence, negation, and order in the Neoplatonic tradition. The central idea is that Neoplatonists assume a logic in which the existence predicate is a comparative adjective and in which monadic predicates function as scalar adjectives that nest the background order. Various scalar predicate negations are then identifiable with various Neoplatonic negations, including a privative negation appropriate for the lower orders of reality and a hyper-negation appropriate for the higher. Reversion to the (...) One can then be explained as the logical inference of hyper-negations from mundane knowledge. Part I develops the relevant linguistic and logical theory, and Part II defends Wolfson and the scalar interpretation against the more traditional Aristotelian understanding of Whittaker and others of reversion as intensional abstraction.

This book sets out for the first time in English and in the terms of modern logic the semantics of the Port Royal Logic of Antoine Arnauld and Pierre Nicole, perhaps the most influential logic book in the 17th and 18th centuries. Its goal is to explain how the Logic reworks the foundation of pre-Cartesian logic so as to make it compatible with Descartes' metaphysics. The Logic's authors forged a new theory of reference based on the medieval notion of objective (...) being, which is essentially the modern notion of intentional content. Indeed, the book's central aim is to detail how the Logic reoriented semantics so that it centered on the notion of intentional content. This content, which the Logic calls comprehension, consists of an idea's defining modes. Mechanisms are defined in terms of comprehension that rework earlier explanations of central notions like conceptual inclusion, signification, abstraction, idea restriction, sensation, and most importantly within the Logic's metatheory, the concept of idea-extension, which is a new technical concept coined by the Logic. Although Descartes is famous for rejecting "Aristotelianism," he says virtually nothing about technical concepts in logic. His followers fill the gap. By putting to use the doctrine of objective being, which had been a relatively minor part of medieval logic, they preserve more central semantic doctrines, especially a correspondence theory of truth. A recurring theme of the book is the degree to which the Logic hews to medieval theory. This interpretation is at odds with what has become a standard reading among French scholars according to which this 16th-century work should be understood as rejecting earlier logic along with Aristotelian metaphysics, and as putting in its place structures more like those of 19th-century class theory.

This book shows otherwise. John Martin rehabilitates Neoplatonism, founded by Plotinus and brought into Christianity by St. Augustine.

This paper explores the modal interpretation of ?ukasiewicz's n -truth-values, his conditional and the puzzles they generate by exploring his suggestion that by ?necessity? he intends the concept used in traditional philosophy. Scalar adjectives form families with nested extensions over the left and right fields of an ordering relation described by an associated comparative adjective. Associated is a privative negation that reverses the ?rank? of a predicate within the field. If the scalar semantics is interpreted over a totally ordered domain (...) of cardinality n and metric ?, an n-valued Lukasiewicz algebra is definable. Privation is analysed in terms of non-scalar adjectives. Any Boolean algebra of 2 n ?properties? determines an n + 1 valued Lukasiewicz algebra. The Neoplatonic ?hierarchy of Being? is essentially the order presupposed by natural language modal scalars. ?ukasiewicz's ≈ is privative negation, and ? proves to stand for the extensional (antitonic) dual if ? then for scalar adjectives, especially modals. Relations to product logics and frequency interpretations of probability are sketched. (shrink)

The paper shows that in the Art of Thinking (The Port Royal Logic) Arnauld and Nicole introduce a new way to state the truth-conditions for categorical propositions. The definition uses two new ideas: the notion of distributive or, as they call it, universal term, which they abstract from distributive supposition in medieval logic, and their own version of what is now called a conservative quantifier in general quantification theory. Contrary to the interpretation of Jean-Claude Parienté and others, the truth-conditions do (...) not require the introduction of a new concept of ‘indefinite’ term restriction because the notion of conservative quantifier is formulated in terms of the standard notion of term intersection. The discussion shows the following. Distributive supposition could not be used in an analysis of truth because it is explained in terms of entailment, and entailment in terms of truth. By abstracting from semantic identities that underlie distribution, the new concept of distributive term is definitionally prior to truth and can, therefore, be used in a non-circular way to state truth-conditions. Using only standard restriction, the Logic’s truth-conditions for the categorical propositions are stated solely in terms of (1) universal (distributive) term, (2) conservative quantifier, and (3) affirmative and negative proposition. It is explained why the Cartesian notion of extension as a set of ideas is in this context equivalent to medieval and modern notions of extension. (shrink)

An investigation of Proclus' logic of the syllogistic and of negations in the Elements of Theology, On the Parmenides, and Platonic Theology. It is shown that Proclus employs interpretations over a linear semantic structure with operators for scalar negations (hypemegationlalpha-intensivum and privative negation). A natural deduction system for scalar negations and the classical syllogistic (as reconstructed by Corcoran and Smiley) is shown to be sound and complete for the non-Boolean linear structures. It is explained how Proclus' syllogistic presupposes converting the (...) tree of genera and species from Plato's diairesis into the Neoplatonic linear hierarchy of Being by use of scalar hyper and privative negations.

In this article, we draw upon the philosophy of critical realism to reflect upon issues concerning discovery processes and opportunity development. First, paradoxes in the relationship between opportunity discovery and creativity are identified and explained. Second, the question of how to investigate opportunities is discussed and a solution informed by critical realism presented whereby three new types of discovery are identified and defined for empirical investigation. Using critical realism to augment entrepreneurial opportunity theory, we propose that discovery processes have significance (...) beyond discovery theory and can be considered revealing for theories of opportunity development more generally. We conclude with conceptual and practical comment on the importance of ontological theorising for entrepreneurship. (shrink)

The mediaeval logic of Aristotelian privation, represented by Ockham's expositionof All A is non-P as All S is of a type T that is naturally P and no S is P, iscritically evaluated as an account of privative negation. It is argued that there aretwo senses of privative negation: (1) an intensifier (as in subhuman), the dualof Neoplatonic hypernegation (superhuman), which is studied in linguistics asan operator on scalar adjectives, and (2) a (often lexicalized) Boolean complementrelative to the extension of (...) a privative negation in sense (1) (e.g., Brute). Thissecond sense, which is the privative negation discussed in modern linguistics, isshown to be Aristotle's. It is argued that Ockham's exposition fails to capture muchof the logic of Aristotelian privation due to limitations in the expressive power of thesyllogistic. (shrink)

The paper explores the existential import of universal affirmative in Descartes, Arnauld and Malebranche. Descartes holds, inconsistently, that eternal truths are true even if the subject term is empty but that a proposition with a false idea as subject is false. Malebranche extends Descartes? truth-conditions for eternal truths, which lack existential import, to all knowledge, allowing only for non-propositional knowledge of contingent existence. Malebranche's rather implausible Neoplatonic semantics is detailed as consisting of three key semantic relations: illumination by which God's (...) ideas cause mental terms, creation by which God's ideas cause material substances by a kind of ?ontic privation?, and sensation in which brain events occasion states of mental awareness. In contrast, Arnauld distinguishes two types of propositions ? necessary and contingent ? with distinct truth-conditions, one with and one without existential import. Arnauld's more modern semantics is laid out as a theory of reference that substitutes earlier causal accounts with one that adapts the medieval notion of objective being. His version anticipates modern notions of intentional content and appeals in its ontology only to substances and their modes. (shrink)

An analysis is proposed for the common argument that something should be preserved because it is irreplaceable. The argument is shown to depend on modal elements in irreplaceable, existence assumptions of preserve, and the logic of obligation. In terms of this theory it is argued that utilitarianism can account for most, but not all instances of persuasive appeals to irreplaceability. Beingessentially backwards looking, utilitarianism cannot in principle justify preservation of objects irreplaceable because of their history or genesis.

Contrary to what might be expected given a religious or other motivation, Pierre Duhem's interest in mediaeval science was the result of his surprise encounter with Jordanus de Nemore while working on Les origines de la statique in the late autumn of 1903. Historical assumptions common among physicists at that time may explain this surprise, which occasioned a frantic search for more mediaeval precursors for Renaissance mechanics. It also raised serious historiographical problems that threatened even his methodological views, until they (...) were resolved in his To save the phenomena of 1908. (shrink)

Let |$\textbf{A}$| be a |$BCK$|-algebra and |$f:A^{k}\rightarrow A$| a function. The main goal of this article is to give a necessary and sufficient condition for |$f$| to be compatible with respect to every relative congruence of |$\textbf{A}$|⁠. We extend this result in some related algebras, as e.g. in pocrims.

A sense of agency over wilful actions is thought to be dependent on the level of choice and the nature of the outcome. In a preregistered study, we manipulated choice and valence of outcome to assess the relationship between SoA across the depression and psychosis continuum. Participants completed a Libet Clock task, in which they had either a free or forced choice to press one of two buttons and received either a rewarding or punishing outcome. Participants also completed questionnaires on (...) depressive and psychosis-like traits. Rewarding outcomes increased intentional binding. The evidence favoured no effect of choice on average, but this was influenced by inter-individual differences. Individuals reporting more depressive traits had less of a difference in intentional binding between free and forced choice conditions. We show that implicit SoA is sensitive to outcome valence and the effect of choice differs across the depression continuum. (shrink)

Quantifiers in Frege's Grundgesetze like are not well-defined because the part Fx & Gx stands for a concept but the yoking conjunction is horizontalised and must stand for a truth-value. This standard interpretation is rejected in favor of a substitutional reading that, it is argued, both conforms better to the text and is well-defined. The theory of the horizontal is investigated in detail and the composite reading of Frege's connectives as made up of horizontals is rejected. The sense in which (...) the Grundgesetze has a many-valued but classical logic is explained by proving that its propositional fragment (under the standard interpretation) and Bochvar's 3-valued logic are instances of the same metatheoretic methods. Historically, the paper argues for a more naive but well-defined reading of the text. Theoretically, it provides a formally adequate statement of that semantics, as well as developing the abstract metatheory which embraces Bochvar's language and the Fregean fragment. (shrink)

The classical theory of preference among monetary bets represents people as expected utility maximizers with concave utility functions. Critics of this account often rely on assumptions about preferences over wide ranges of total wealth. We derive a prediction of the theory that bears on bets at any fixed level of wealth, and test the prediction behaviorally. Our results are discrepant with the classical account. Competing theories are also examined in light of our data.

An interpretation in modal and tense logic is proposed for Boethius's reconciliation of God's foreknowledge with human freedom from The consolation of philosophy, Book V. The interpretation incorporates a suggestion by Paul Spade that God's special status in time be explained as a restriction of God's knowledge to eternal sentences. The argument proves valid, and the seeming restriction on omnipotence is mitigated by the very strong expressive power of eternal sentences.

The author addresses the question of the necessity of logic courses in undergraduate education, particularly their use as a requirement in the humanities. This paper outlines why logic counts as a humanities subject and why certain virtues of logic are beneficial to a humanities education. The authors explores these two aspects of the question and invites the reader to decide whether the combination of these two aspects of a logic course jointly satisfy the educational needs of their particular institution’s curriculum.

Much speculation on the sources of Duhem's historical interests fails to account for the major shifts in these interests: neither his belief in the continuous development of physics nor his Catholicism, when his Church was encouraging the study of generally Aristotelian scholastic thought, led to any interest in mediaeval science before 1904. Equally, his own claim that he was merely testing his views on the nature of physical theory is easily squared only with earlier work with no trace of mediaeval (...) science. Behind this discontinuity lies a major crisis. Though not a positivist, Duhem had based all his work on assumptions acceptable to positivists. One of these, the sterility of the Middle Ages, was refuted by his chance discovery of evidence of genuine mediaeval science in the autumn of 1903, but that left the doctrine of scholastic sterility intact.

Exploring how people represent natural categories is a key step toward developing a better understanding of how people learn, form memories, and make decisions. Much research on categorization has focused on artificial categories that are created in the laboratory, since studying natural categories defined on high-dimensional stimuli such as images is methodologically challenging. Recent work has produced methods for identifying these representations from observed behavior, such as reverse correlation (RC). We compare RC against an alternative method for inferring the structure (...) of natural categories called Markov chain Monte Carlo with People (MCMCP). Based on an algorithm used in computer science and statistics, MCMCP provides a way to sample from the set of stimuli associated with a natural category. We apply MCMCP and RC to the problem of recovering natural categories that correspond to two kinds of facial affect (happy and sad) from realistic images of faces. Our results show that MCMCP requires fewer trials to obtain a higher quality estimate of people’s mental representations of these two categories. (shrink)

Using concepts from abstract algebra and type theory, I analyze the structural presuppositions of any holistic ethical theory. This study is motivated by such recent holistic theories in environmental ethics as Aldo Leopold’s land ethic, James E. Lovelock’s Gaia hypothesis, Arne Naess’ deep ecology, and various aesthetic ethics of the sublime. I also discuss the holistic and type theoretic assumptions of suchstandard ethical theories as hedonism, natural rights theory, utilitarianism, Rawls’ difference principle, and fascism. I argue that although there are (...) several common senses of part-whole in ethical theory, the central sense of holism in ethics is that of a theory that defines its key moral idea as an emergent group property grounded in the relational properties of its individual constituents. Hedonism and Kantianism do not count as holistic in this sense. Natural rights theory does in adegenerate way. Utilitarianism and various environmental ethics are paradigm examples. I point out as a general structural weakness of environmental holistic theories that their first-order grounding in nonmoral vocabulary seems to preclude an explanation of many moral intuitions about human ethics.

Carl Henry devotes a few chapters directly (and a few indirectly) in volume 6 of his God, Revelation, and Authority [GRA] to the problem of evil [POE]. The author examines Henry’s contribution as a theologian, noting that GRA is a work of theology, not philosophy proper. However, Henry had a PhD in Philosophy (Boston, 1949), and one finds present several presuppositions and control beliefs that are philosophically motivated. Observation of the text reveals several of these. Chief here is Henry’s working (...) assumption that to understand and explain the nature of evil, one must first understand and explain the nature, origin and etiology of good. This point and its implications are developed at length in this article. Unsurprising is Henry’s contribution exhibiting an awareness of methods and theodical approaches traditionally used by philosophers of religion such as Rowe, Plantinga, and Hick. Surprising is the fact that Henry does not clearly take a side on the nature of human free will. What he does say seems to underdetermine his exact position. Finally, the importance of Kant vis a vis Henry’s theodicy and entire theological program is emphasized as well. (shrink)
