The aim of this paper is to discuss the theory of exemplary causality of Peter Auriol (1280-1322). Until at least the late 13th century, medieval authors claim that the world is orderly and intelligible because God created it according to the models existing eternally in his mind (i.e. divine ideas). Auriol challenges the view of his predecessors and contemporaries. He argues that assuming divine ideas amounts to assuming multiplicity in God and therefore questioning the principle of his absolute simplicity. (...) To avoid this problem, he develops a system that enables him to account for God’s knowledge of creatures (both as individuals and as species) and hence to preserve the theological principle of providence, but at the same time allows him to reject divine ideas as intermediaries for creation. In Auriol’s theory of exemplary causality, divine essence is the only object of God’s knowledge and thus the only exemplar for creation. God’s cognitive act is directed exclusively towards his own essence. However, he knows creatures through multiple connotations, i.e. the multiple ways divine essence is connotated when God knows himself. But these connotations play no role in creation, because imitability is only proper to divine essence. To explain how an object can be the only exemplar for the creation of many different creatures, Auriol has to rethink the concept of imitability and develop a new model of exemplary causality enabling him to account for the relationship between God and his creatures. The traditional model was that of analogy: a cause produces an effect which is partly similar and partly different from it. Auriol relies on the concept of equivocity. He argues that it is unnecessary to assume a particular similarity between a cause and its effect. Quite the contrary: for an object to be the exemplar of multiple different things, it is necessary that it should not be similar to any of them. The concept of aequivocatio allows Auriol to reject the traditional model of creation. Aequivocatio does not entail a resemblance between idea and ideatum. There is no contradiction, then, in claiming that a single object (divine essence) is in an equivocal way (aequivoce) the exemplary cause of multiple different objects. This is Auriol’s new theory of divine exemplarism: the theory of similitudo aequivoca. (shrink)

A central question in cognitive research concerns how new properties are generalized to categories. This article introduces a model of how generalizations involve a process of causal inference in which people estimate the likely presence of the new property in individual category exemplars and then the prevalence of the property among all category members. Evidence in favor of this causal‐based generalization (CBG) view included effects of an existing feature’s base rate (Experiment 1), the direction of the causal relations (Experiments 2 (...) and 4), the number of those relations (Experiment 3), and the distribution of features among category members (Experiments 4 and 5). The results provided no support for an alternative view that generalizations are promoted by the centrality of the to‐be‐generalized feature. However, there was evidence that a minority of participants based their judgments on simpler associative reasoning processes. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Mary as the Exemplar of the Body's PovertyAngela FranksRecent MariologyFollowing the trajectory of Mariology and Marian devotion for the last century or so is enough to give one whiplash. On the one hand, the declaration of the doctrine of Mary's Assumption in 1950 by Pope Pius XII represents a strand of Mariology that emphasizes her divinely granted prerogatives and glory. In popular piety, this dogmatic emphasis was mirrored (...) by devotional practices that stressed Mary's mediatorial power.1 On the other hand, many theologians were concerned that such teaching and practice obscured the centrality of Christ, the Church, and the liturgy in Christian life.2 One could see the placing of Mary within chapter 8 of Lumen Gentium less than fifteen years after the declaration of the Assumption as a rebalancing of Mariology. Lumen Gentium (LG) resituated Mary within the doctrine of the Church, echoing patristic equations of Our Lady with the Church.3 One unintended effect of the conciliar move, however, was to make devotion to Mary seem unnecessary, despite the efforts of [End Page 1097] post-conciliar popes to encourage Marian piety—in particular, John Paul II, with his Marian motto Totus Tuus.John Paul II is in many ways an exemplar of conciliar Marian devotion. His Mariology integrates Mary into ecclesiology by emphasizing her role as the paradigmatic follower of Christ.4 This discipleship is, he is careful to say, due to her maternal role and the extraordinary graces that followed from it.5 But these graces did not eliminate her need to follow her son closely; rather, they made such discipleship possible.This interplay between Mary's need and the unique graces granted to meet that need is perhaps clearest in John Paul II's presentation of Mary's faith.6 This attitude of faith is "central" to John Paul II's presentation of Mary in the encyclical Redemptoris Mater (RM), according to Joseph Ratzinger.7 Because of her faith, which is based on the prior action of God in her life (§38, quoting LG §60), she is due "a wealth of praise" that "is more than ever necessary today" (RM §34). In John Paul II, the seeming either-or of twentieth-century Mariology is dissolved, but through the introduction of a causal relationship between the two. In other words, [End Page 1098] Mary's poverty—her need for and receptivity to God—is what makes her able to be rich, to be worthy of a wealth of praise.Perhaps surprisingly, John Paul Il's presentation of Mary as transparent to the mystery of Christ echoes his theology of the body. There, he repeats a hylomorphic maxim: "The body reveals the person." In this revelation, the poverty and the wealth of the body coincide. The body is of great dignity: it can reveal the person. But it is also poor, because it does not reveal itself but rather is transparent to the inner personal mystery. In this, it resembles Mary.This essay will pick up the trail laid down by John Paul II by examining Mary under the rubric of her poverty. Her poverty, I will argue, is exemplary for the poverty of the body, and neither Mary nor the body can be understood properly without understanding poverty. In this essay, I will explore these topics by looking at the Mariology of John Paul II and Hans Urs von Balthasar, before turning to what this Mariology means for the body and for creation in general.Mary's PovertyRedemptoris Mater presents Mary as a model of pilgrim faith, one who "goes before" us on the pilgrimage (RM §§5–6 and 25–28). Mary's reliance upon faith places her among the anawim, the poor of the Lord. John Paul II quotes §55 of Lumen Gentium to note that Mary "stands out among the poor and humble of the Lord, who confidently await and receive salvation from him" (RM §§8 and 11). As the Congregation for the Doctrine of the Faith under Joseph Ratzinger wrote around the time of the Marian encyclical, she is "totally dependent upon God and completely directed towards him, and at the side of her Son, she is...

A theory of categorization is presented in which knowledge of causal relationships between category features is represented in terms of asymmetric and probabilistic causal mechanisms. According to causal‐model theory, objects are classified as category members to the extent they are likely to have been generated or produced by those mechanisms. The empirical results confirmed that participants rated exemplars good category members to the extent their features manifested the expectations that causal knowledge induces, such as correlations between feature pairs that are (...) directly connected by causal relationships. These expectations also included sensitivity to higher‐order feature interactions that emerge from the asymmetries inherent in causal relationships. Quantitative fits of causal‐model theory were superior to those obtained with extensions to traditional similarity‐based models that represent causal knowledge either as higher‐order relational features or “prior exemplars” stored in memory.

Gregory T. Doolan provides here the first detailed consideration of the divine ideas as causal principles. He examines Thomas Aquinas's philosophical doctrine of the divine ideas and convincingly argues that it is an essential element of his metaphysics. According to Thomas, the ideas in the mind of God are not only principles of his knowledge, but they are productive principles as well. In this role, God's ideas act as exemplars for things that he creates. As Doolan shows, this theory of (...) exemplarism is an integral part of Thomas's account of the existence and order of the created universe. It also accounts in part for the freedom of God's creative act. The volume begins with an introduction to Thomas's doctrine of exemplarism and then addresses his arguments for the existence of exemplar ideas within the mind of God. Having established the existence of divine ideas, Doolan considers how Thomas reconciles their multiplicity with God's simplicity. The work identifies the various things for which Thomas posits divine ideas. As Doolan is careful to show, Thomas does not consider all of these ideas to be exemplars because not all of them act as causal principles. After identifying the ideas that do act in this way, Doolan considers how such exemplars can be causes of natural things without compromising the causality of natural agents. The volume culminates with a consideration of the role that the divine ideas play within the structure of Thomas's theory of participation. ABOUT THE AUTHOR: Gregory T. Doolan, assistant professor of philosophy at The Catholic University of America, is a contributor to Wisdom's Apprentice: Thomistic Essays in Honor of Lawrence Dewan, O.P., and Reassessing the Liberal State: Reading Maritain's Man and the State.

RESUMOA climatologia está no centro de um dos debates mais polarizados da atualidade, apresentado como confronto entre os defensores da existência de um aquecimento global antropogênico e aqueles que rejeitam sua existência. A instituição chave para esse tema é o Painel Intergovernamental sobre Mudanças Climáticas, um corpo simultaneamente científico e político. O debate surge aí mesclado com a discussão política sobre as respostas adequadas ao aquecimento global. Mas, rechaçados nesse terreno, os negacionistas transpõem o debate para a mídia, onde mobilizam (...) a pseudociência para deslegitimar as conclusões das disciplinas científicas ligadas ao entendimento do clima. Temos, assim, uma produção consciente da ignorância em larga escala sobre o tema do aquecimento global, demandando o uso da agnotologia para desvendar o mecanismo de produção da ignorância. A climatologia revela-se, então, um campo exemplar para o estudo da inserção histórico-social do conhecimento científico e das tensões e trajetórias conflitivas no seu interior, dos dilemas éticos que coloca e das possibilidades universalistas do conhecimento científico na era da tecnociência. ABSTRACTClimatology is at the center of one of the most polarized debates of today. It is presented as a confrontation between supporters of the existence of anthropogenic global warming and those who deny its existence. The key institution for this theme is the Intergovernmental Panel on Climate Change, which is both a scientific and political body. In this context, the debate arises merged with the political discussion on appropriate responses to global warming. However, contested on this ground, the deniers transfer the debate to the media, mobilizing pseudo-science to delegitimize the conclusions of the scientific disciplines related to climate understanding. Therefore, we have a deliberate production of large-scale ignorance on this subject, which requires the use of agnotology to unravel it. Thus, climatology reveals itself an exemplary space to study the historical and social roots of scientific knowledge and the tensions and conflicting trajectories inside it, the ethical dilemmas posed and the universalist possibilities of scientific knowledge in the age of technoscience.

The causal view of categories assumes that categories are represented by features and their causal relations. To study the effect of causal knowledge on categorization, researchers have used Bayesian causal models. Within that framework, categorization may be viewed as dependent on a likelihood computation (i.e., the likelihood of an exemplar with a certain combination of features, given the category's causal model) or as a posterior computation (i.e., the probability that the exemplar belongs to the category, given its features). (...) Across three experiments, in combination with computational modeling, we offer evidence that categorization is better accounted for by assuming that people compute posteriors and not likelihoods, though both probabilities are closely related. This result contrasts with existing analyses of causal-based categorization, which assume that likelihood computations give a good approximation of human judgments. We also find that people are able to compute likelihoods in a closely related task that elicits judgments of consistency rather than category membership judgments. Our analyses show that people do use causal probabilistic information as prescribed by a Bayesian model but that they flexibly compute likelihoods or posteriors depending on the task. We discuss our results in relation to the relevant literature on the topic. (shrink)

The purpose of this study is to analyze the experience of hope that appears in a parent's blog presenting everyday life while caring for a child with Trisomy 18 (Edwards syndrome). The author, Rebekah Peterson, began her blog on 17 March 2011 and continues to post information on her son Aaron's care. The analysis of hope in the blog is carried out using a mixed methodology: initial and focused coding using Charmaz's constructed grounded theory and elements of Colaizzi's method. Each (...) aspect of hope is coded through the blog author's statements, from which three main aspects of hope emerge: hope for the longest possible presence of Aaron with his family, hope for control over situations, pain, and symptoms, and existential facets of hope. These various aspects reveal to what extent the experience of hope is unique. Additionally, analyzing the experience of parental hope uncovers the additional problem of inappropriate communication by health care professionals (HCPs) in intensive care units, particularly when discussing the termination of causal treatment. The problem may be solved through proper education for HCPs and serious consideration of parental involvement in order to properly elaborate guidelines on this issue. The three main aspects of parental hope discussed in this paper might expand knowledge on the issue, helping HCPs to better understand the parents' experience of care and to help sustain parental hope in pediatric palliative care.

The inculcation of academic integrity among post-graduate students is an ongoing concern for universities across the world. While various researchers have focused on causal relations between forms of instruction, student characteristics, and possession of academic integrity, there is need for an increased examination of the role of supervisors in shaping student perceptions of academic integrity. Unlike the undergraduate level, where student interaction with professors is often limited, post-graduate students have an ongoing relationship with their supervisors, whether at the Masters or (...) Doctorate level. In some ways like masters over apprentices, rather than teachers over students, supervisors engage in continued interaction with post-graduate students, shaping these students views not only on the substance of their research, but also in how researchers “should” act. As part of a larger project in examining post-graduate student opinions on academic integrity and research ethics, we conducted surveys to investigate the relationship between student perceptions of their supervisors and student perceptions of academic integrity. We use survey data from a population of post-graduate students at a comprehensive research university in Hong Kong to analyze student perceptions of academic integrity and how students might be influenced by their supervisors’ service as mentors and/or ethic exemplars.

The author’s purpose is to understand the role divine ideas play as causal principles in Aquinas’s philosophy. His contention is that, although Thomas’s doctrine of ideas is perhaps not the key to an understanding of his metaphysics, it is certainly “ a key to such an understanding” .The book is divided into six chapters. The first chapter seeks to provide a general definition of divine ideas according to Aquinas. Divine ideas are exemplar causes in the likeness of which God (...) produces creatures. Ideas in the strict sense belong to God’s practical or actually practical knowledge. The causality exercised by exemplars is that of formal causality, but because they are productive of things, they entail efficient and final causality, as well. In chapter 2, Doolan examines Thomas’s arguments in favor of the existence of divine ideas. Chapter 3 deals with the question of the multiplicity of divine ideas. Doolan first establishes, against Gilson and others, that Aquinas did indeed hold that there was a multiplicity of divine ideas. He then shows how Aquinas was able to reconcile the diversity of ideas with God’s simplicity. The gist of the solution involves viewing ideas as nonbeings relative to God, who is, of course, ipsum esse. Now the only way non-beings can enter into God is in. (shrink)

A growing consensus in the philosophy and psychology of concepts is that while theories such as the prototype, exemplar, and theory theories successfully account for some instances of concept formation and application, none of them successfully accounts for all such instances. I argue against this ‘new consensus’ and show that the problem is, in fact, more severe: the explanatory force of each of these theories is limited even with respect to the phenomena often cited to support it, as each (...) fails to satisfy an important explanatory desideratum with respect to these phenomena. I argue that these explanatory shortcomings arise from a shared assumption on the part of these theories, namely, they take similarity judgements and application of causal knowledge to be discrete elements in a theory of concepts. I further propose that the same assumption carries over into alternative theories offered by proponents of the new consensus: pluralism, eliminativism, and hybrid theories. I put forth a sketch of an integrated model of concept formation and application, which rejects this shared assumption and satisfies the explanatory desiderata I discuss. I suggest that this model undermines the motivation for hybrid, pluralist, and eliminativist accounts of concepts. _1_ Introduction _2_ The Similarity-Based Approach and the Importance of Theory _2.1_ The similarity-based approach _2.2_ The selection desideratum _2.3_ Causal knowledge as satisfying the selection desideratum _3_ The Theory-Based Approach and the Importance of Similarity _3.1_ The theory-based approach _3.2_ The range desideratum _3.3_ Similarity as satisfying the range desideratum _4_ An Integrated Approach to Concepts _4.1_ An integrated model _4.2_ The integrated theory versus hybrid theories of concepts _5_ Conclusion.

Discussion of divine providence was traditionally grounded in the wisdom and benevolence of the Creator, until the impact of nominalism which narrowed the theological focus upon the absolute power and freedom of the divine will. An exemplary approach for discussing providence which predates nominalism and which has surprising contemporary relevance is the one developed by Thomas Aquinas in his Summa Theologiae. It is exemplary both for how it discusses providence and for what is says about it. Methodologically, Aquinas explains providence (...) in two contexts, one theological, the other cosmological, in order to avoid misconstruing the reality of one term because of the dynamics pertinent to the other. Substantively, this understanding of providence rests upon the theological foundation of the Creator’s wisdom and benevolence, which in the world find expression as a comprehensive order oriented towards emergent goodness. Through this order God is provident by the genuine and contingent causal actions of creatures, a natural and non‐deterministic means that makes it highly compatible with modern science. (shrink)

What are scientific theories and how should they be represented? In this article, I propose a causal–structural account, according to which scientific theories are to be represented as sets of interrelated causal and credal nets. In contrast with other accounts of scientific theories (such as Sneedian structuralism, Kitcher’s unificationist view, and Darden’s theory of theoretical components), this leaves room for causality to play a substantial role. As a result, an interesting account of explanation is provided, which sheds light on (...) explanatory unification within a causalist framework. The theory of classical genetics is used as a case study. 1 Introduction2 The Theory of Classical Genetics3 Three Philosophical Accounts of the Theory of Classical Genetics3.1 The structuralist account3.2 Kitcher’s unificationism3.3 Darden and theory change in science4 A Common Lacuna: Where is Causality?5 Woodward’s Interventionist Account of Causation6 Causal Bayes Nets and Their Interrelations6.1 Causal Bayes nets6.2 Relations among causal nets6.3 Credal nets and their interrelations7 The Theory of the Gene and its Causal Graph8 A First Exemplar: Stem Length in Pea Plants8.1 Three crosses on stem length in pea plants8.2 The causal graph for stem length in pea plants8.3 Morgan’s explanatory principles and the credal net for stem length in pea plants9 Explaining Mendel’s Crosses: A Causal–Structural Account10 Monohybrid Crosses with Complete Dominance11 Exemplars,Explanatory Patterns, Generic Credal Nets, and Mechanism Schemas12 Incomplete Dominance13 Anomalies14 Multi-hybrid Crosses with Independent Assortment15 Multi-hybrid Crosses with Linkage and Crossing-Over16 Double Crossing-Over and the Linear Order of the Gene17 Causal–Structural Explanation18 Explanatory Unification19 Concluding Remarks.

This article is a contribution to the field of study that Jacques Maritain once described as “metaphysical Axiomatics.” I discuss Aquinas’s use of the metaphysical principle “omne agens agit sibi simile,” focusing on perhaps the most manifest instance of this principle, namely, univocal generation. It is well known that Aquinas holds what could be called a “static” or “formal” view of likeness between God and creatures: creatures are like God because they share in certain exemplar perfections that preexist in (...) God. My focus instead is on an efficient likeness to God, which reflects a foundational truth about reality for Aquinas: all creatures produce something like themselves through their operations, in imitation of God, who does so on a more fundamental level. My discussion will also clarify Aquinas’s derivation of the principle of similitude from a prior metaphysical principle, “every agent acts insofar as it is in act.”. (shrink)

David Bohm's interpretation of quantum mechanics yields a quantum potential, Q. In his early work, the effects of Q are understood in causal terms as acting through a real (quantum) field which pushes particles around. In his later work (with Basil Hiley), the causal understanding of Q appears to have been abandoned. The purpose of this paper is to understand how the use of certain metaphors leads Bohm away from a causal treatment of Q, and to evaluate the use of (...) those metaphors. (shrink)

This article offers a reading of Eriugena’s thought that is inspired by Heidegger’s claim according to which being is constituted in a dialectical interplay of revelation and concealment. Beginning with an analysis of how “causality as concealing revelation” works on the level of God’s inner-Trinitarian life, the piece moves on to a consideration of the way in which the human soul reveals itself in successive stages of exteriorization that culminate in the creation of the body, its “image.” The body, (...) however, conceals as much as it reveals true human nature. Moreover, it is shown that for Eriugena all of reality, as theophany, possesses this character of concealing its fundamental truth. These insights lead Eriugena to a recognition of radical human finitude, as genuine wisdom requires an acknowledgement of our fundamental ignorance. (shrink)

Zusammenfassung Der Aufsatz untersucht die Theorie der exemplarischen Kausalität von Petrus Aureoli (1280–1322). Mindestens bis zur zweiten Hälfte des 13. Jahrhunderts behaupteten mittelalterliche Autoren, dass die Welt geordnet und intelligibel war, weil Gott sie nach aus der Ewigkeit in seinem Intellekt existierenden Modellen (d.h. göttlichen Ideen) geschaffen hatte. Aureoli focht diese traditionelle Ansicht an. In Aureolis Theorie ist die göttliche Essenz das einzige Urbild für die Erschaffung. Um zu erklären, wie ein einziges Objekt allein als Urbilder für die Erschaffung mehrerer (...) verschiedener Kreaturen fungieren kann, muss er den Begriff der Nachahmbarkeit neu überdenken und ein neues Modell der exemplarischen Kausalität entwickeln. Das traditionelle Modell war das der Analogie: Eine Ursache erzeugt einen Effekt, der zum Teil ähnlich wie sie und zum Teil anders als sie ist. Aureoli greift auf den Be-griff von Äquivokation zurück. Er argumentiert, dass keine direkte Ähnlichkeit zwischen Ursache und Effekt notwendig ist. Im Gegenteil: Damit ein Objekt das Urbild für mehrere verschiedene Dinge sein kann, ist es notwendig, dass es für keinen von ihnen repräsentativ ist. Der Begriff der Äquivokation erlaubt es Aureoli, das traditionelle Modell der Erschaffung abzulehnen. Aequivocatio sieht keine Ähnlichkeit zwischen Idee und Ideatum vor. Es be-steht also kein Widerspruch darin, wenn man sagt, dass ein einziges Objekt (göttliche Essenz) aequivoce die exemplarische Ursache für mehrere verschiedene Objekte ist. (shrink)

Le Quaestiones 2 («Se l’oggetto adeguato della conoscenza divina sia l’essenza di Dio o l’ente universale») e 3 («Se le creature secondo le loro proprie nature e le loro essenze siano vita in Dio e nel Verbo») della Distinctio 35 dello Scriptum di Pietro Aureoli sono importanti per la ricostruzione sia del pensiero del loro autore che della storia della dottrina delle idee divine nel Medioevo. Aureoli rifiuta il modello tradizionale di causalità esemplare, secondo cui Dio avrebbe creato il mondo (...) sulla base di modelli archetipi esistenti dall’eternità nella sua mente. Ricorrendo al concetto di aequivocatio, stabilisce che l’essenza di Dio è in maniera equivoca l’unico esemplare per tutte le creature ed elabora, così, la teoria della causalità esemplare equivoca.

Over time, Aristotle’s theory of four causes lost some of their original flexibility as an instrument to be applied analogically in diverse sciences. Enrico Berti’s distinction between physical and metaphysical causality in Aristotle provides insight into overcoming this crystallization. More importantly, the novelty of Aquinas’ metaphysics of actus essendi calls for a revision of the four causes: first, actus essendi is presented as actuating act and the source of the finite being’s ordered operation; the substantial essence falls to potency (...) and specifies the act of being; the efficient cause is the power of God insofar as he produces and moves the creature; divine exemplar causality is twofold ; the final causality concerns both the order and the governance of the world. In this paper, then, I outline this analogical passage from Aristotle’s physical causality to Aquinas’ metaphysical causality in reference to their modern interpreters, like Enrico Berti and Jan A. Aertsen. (shrink)

The broad topic of this paper is the relationship between the theoretical notion of a concept and familiar types of cognitive structures (prototypes, exemplars, causal models, etc.) The discussion is organized around different ways that theorists about concepts can attempt to accommodate what has been dubbed the Heterogeneity Hypothesis (roughly: the claim that various types of structures with which concepts have been identified co-exist and form a heterogeneous class). The most general goal of the paper is to clarify the dialectical (...) geography when it comes to different ways of construing the relationship between concepts and familiar cognitive structures. A more focussed and more polemical goal of the paper is to raise problems for so-called pluralist approaches to concepts. This paper will not offer a comprehensive defense of any particular view about the relationship between concepts and cognitive structures, but the discussion will be a convenient venue in which to highlight some virtues of what I will call Higher-Level Unity approaches to concepts.

If, as Augustine taught, the rational powers of the mind are made in the image of the Trinity, it stands to reason that there would be discernible parallels between trinitarian relations and epistemological relations. According to Bonaventure, the Trinity in general, and the Word in particular, provides the model and guarantor for human knowledge. Since knowledge is inherently relational, the basic relations of causality, similitude, and assimilation and expression that Bonaventure finds operative within the Trinity are also key elements (...) of human knowledge. The human mind most images the Trinity when it operates according to exemplar causality, expressing its habitual knowledge as a pattern according to which it fashions objects in the world. I suggest that no philosophical description of human cognition can be successful without accounting for the role that causality, similitude, and expression play in human knowledge. (shrink)

The second wave of devastating consequences of the COVID-19 pandemic has been linked to dramatic declines in well-being. While much of the well-being literature is based on descriptive and correlational studies, this paper evaluates a growing body of causal evidence from high-quality randomized controlled trials (RCTs) that test the efficacy of positive psychology interventions (PPIs). This systematic review analyzed the findings from 25 meta-analyses, 42 review papers, and the high-quality RCTs of PPIs designed to generate well-being that were included within (...) those studies. Findings reveal PPIs have the potential to generate well-being even during a global pandemic, with larger effect sizes in non-Western countries. Four exemplar PPIs—that have been tested with a high-quality RCT, have positive effects on well-being, and could be implemented during a global pandemic—are presented and discussed. Future efforts to generate well-being can build on this causal evidence and emulate the most efficacious PPIs to be as effective as possible at generating well-being. However, the four exemplars were only tested in WEIRD (Western, Educated, Industrial, Rich, and Democratic) countries but seem promising for implementation and evaluation in non-WEIRD contexts. This review highlights the overall need for more rigorous research on PPIs with more diverse populations and in non-WEIRD contexts to ensure equitable access to effective interventions that generate well-being for all.

This paper focuses on the theory of divine ideas of Walter Burley. The medieval common theory of divine ideas, developed by Augustine, was intended to provide an answer to the question of the order and intelligibility of the world. The world is rationally organized since God created it according to the models existing eternally in his mind. Augustine's theory, however, left open problems such as reconciling the principle of God's unity with the plurality of ideas, the way in which ideas (...) can or cannot be said to be eternal, their ontological status. Medieval authors discussed such questions until at least the late 14th century. By resorting to the semantic tool of connotation, Burley explains both in what way ‘idea' can signify the divine essence as much as the creatures, and in what sense we can say that God has thought them from eternity, without slipping into a necessitarian view that undermines the principle of divine freedom. Moreover, by envisaging the objective mode of being as the only mode of being of ideas, he explains in what way they truly differ from one another on the basis of their different conceptual contents.

Social determinants of health are a subject of growing interest, yet criticisms have emerged about the way determinants are conceptualized in nursing. A tendency to focus on readily observable living conditions and measurable demographic characteristics can divert attention, it has been said, from the less visible underlying processes which shape social life and health. To illustrate how the analytic perspective determines what becomes visible or invisible as a “determinant” in health, this paper presents a case exemplar. Drawing from news (...) reports and research in real estate economics and urban policy analysis, it explores a single local infectious illness outbreak through a series of progressively more abstract units of inquiry, considering mechanisms of lending and debt financing, housing supply, property valuation, tax policy, change in the structure of the financial industry, and international patterns of migration and capital flow, among other factors, which contributed in various ways to creating unsafe living conditions. An analytic exercise calling attention to dynamism and complexity in social processes, the paper offers a political‐economy‐based approach that serves as a cautionary note against oversimplification in discussions of health causality.

an exemplar of an approach that takes the human mind to be largely the product of social and cultural factors with negligible contributions from biology. The author argues that on the contrary, his sociological theory of the categories is compatible with the possibility of innate cognitive capacities, taking causal cognition as his example. Whether and to what extent there are such innate capacities is a question for research in the cognitive neurosciences. The extent to which these innate capacities can (...) then be explained by natural selection remains an open question for empirical investigation.

In this thesis I argue that the psychological study of concepts and categorisation, and the philosophical study of reference are deeply intertwined. I propose that semantic intuitions are a variety of categorisation judgements, determined by concepts, and that because of this, concepts determine reference. I defend a dual theory of natural kind concepts, according to which natural kind concepts have distinct semantic cores and non-semantic identification procedures. Drawing on psychological essentialism, I suggest that the cores consist of externalistic placeholder essence (...) beliefs. The identification procedures, in turn, consist of prototypes, sets of exemplars, or possibly also theory-structured beliefs. I argue that the dual theory is motivated both by experimental data and theoretical considerations. The thesis consists of three interrelated articles. Article I examines philosophical causal and description theories of natural kind term reference, and argues that they involve, or need to involve, certain psychological elements. I propose a unified theory of natural kind term reference, built on the psychology of concepts. Article II presents two semantic adaptations of psychological essentialism, one of which is a strict externalistic Kripkean-Putnamian theory, while the other is a hybrid account, according to which natural kind terms are ambiguous between internalistic and externalistic senses. We present two experiments, the results of which support the strict externalistic theory. Article III examines Fodor’s influential atomistic theory of concepts, according to which no psychological capacities associated with concepts constitute them, or are necessary for reference. I argue, contra Fodor, that the psychological mechanisms are necessary for reference. (shrink)

The recent use of typicality in statistical mechanics for foundational purposes has stirred an important debate involving both philosophers and physicists. While this debate customarily focuses on technical issues, in this paper I try to approach the problem from an epistemological angle. The discussion is driven by two questions: (1) What does typicality add to the concept of measure? (2) What kind of explanation, if any, does typicality yield? By distinguishing the notions of `typicality-as-vast-majority' and `typicality-as-best-exemplar', I argue that (...) the former goes beyond the concept of measure. Furthermore, I also argue that typicality aims at providing us with a form of causal explanation of equilibrium. (shrink)

Nietzsche subjects traditional philosophical causality to a skeptical critique. With the moderns, he rejects form as superficial. Against the moderns, he findsphysical laws and their ground in a free consciousness equally superficial, and he thinks that the principle of utility is ultimately life denying. However, Nietzscheis not a skeptic, and he has his own doctrine of causality centered on the noble power of the philosopher. The philosopher has the ability to impose new purposes, and this power is the (...) culmination of nature and history. The philosopher believes himself to be a kind of exemplar cause, the consummation of the whole. His is not an instrumental good but one sought for its own sake. (shrink)

The key problem in the controversy over group selection is that of defining a criterion of group selection that identifies a distinct causal process that is irreducible to the causal process of individual selection. We aim to clarify this problem and to formulate an adequate model of irreducible group selection. We distinguish two types of group selection models, labeling them type I and type II models. Type I models are invoked to explain differences among groups in their respective rates of (...) production of contained individuals. Type II models are invoked to explain differences among groups in their respective rates of production of distinct new groups. Taking Elliott Sober's model as an exemplar, we argue that although type I models have some biological importance--they force biologists to consider the role of group properties in influencing the fitness of organisms--they fail to identify a distinct group-level causal selection process. Type II models if properly framed, however, do identify a group-level causal selection process that is not reducible to individual selection. We propose such a type II model and apply it to some of the major candidates for group selection. (shrink)

This paper examines some aspects of Spinoza's metaphysics of the essences of modes.2 I situate Spinoza's use of the notion of essence as a response to traditional, Aristotelian, ways of thinking about essence. I argue that, although Spinoza rejects part of the Aristotelian conception of essence, according to which it is in virtue of its essence that a thing is a member of a kind, he nevertheless retains a different part of such a conception, according to which an essence is (...) some structural feature of a thing which causally explains other, non-essential features. I go on to develop an account of Spinoza's metaphysics of essence, according to which essences, what he sometimes calls formal essences, are produced by the divine essence prior to and independent of the creation of finite modes, and according to which essences are the formal or exemplar causes of finite modes. I then argue that finite modes, in virtue of the formal essences which they actualize, are genuine causal relata. Finally, I offer some speculations about Spinoza's answer to the question, "Why, in a necessitarian cosmos filled with formal essences, should there be temporal finite modes at all?". (shrink)

Whether, and in what sense, research in phenomenology and phenomenological psychopathology has—in addition to its descriptive and hermeneutic value—explanatory power is somewhat controversial. This paper shows why it is legitimate to recognize such explanatory power. To this end, the paper analyzes two central concerns underlying the debate about explanation in phenomenology: (a) the warning against reductionism, which is implicit in a conception of causal explanation exclusively based on models of natural/physical causation; and (b) the warning against top-down generalizations, which neglect (...) the specificity of the individual. While acknowledging that these two caveats express serious concerns regarding the debate on explanatory models, I show that phenomenology has the resources to respond to them. These can be found in analyses of different types of causation relating to different regions of reality and in the structure of explanatory models based on exemplarity. On the basis of these analyses, I defend a pluralist account vis-à-vis explanatory models. (shrink)

In view of the fact that culture-inclusive psychology has been eluded or relatively ignored by mainstream psychology, the movement of indigenous psychology is destined to develop a new model of man that incorporates both causal psychology and intentional psychology as suggested by Vygotsky . Following the principle of cultural psychology: “one mind, many mentalities” , the Mandala Model of Self and Face and Favor Model were constructed to represent the universal mechanisms of self and social interaction that can be applied (...) to any culture; both models can be used as conceptual frameworks for analyzing mentalities of people in any given culture. Taking research works from Foundations of Chinese Psychology: Confucian Social Relation as exemplars , this article illustrates how to construct culture-inclusive theories of Confucianism by multiple philosophical paradigms. The mechanism of culture-inclusive theory can be applied to explain qualitative research findings on lifeworld events of people in a particular society. It can also be utilized to predict results of quantitative research conducted to verify theoretical propositions in the scientific microworld by empirical methods. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:31 Hunie on Intuitive and Demonstrative Inference This paper is divided into four sections. The first section deals with Hume's attempt to resolve a dilemma concerning the objects of intuitive and demonstrative inference. In the second section I try to show that his resolution of the dilemma is hard to reconcile with his phenomenalist doctrine of the origin of ideas. In the third section I examine tne meaning of (...) "intuition" in Hume. Finally, in the fourth section I compare his view of mathematical inference with his view of causal inference, a kind of inference to which he tends to assimilate the former. What are the objects of intuitive and demonstrative inference in Hume supposed to be? In the Treatise they are co-extensive with four kinds of philosophical relations resemblance, contrariety, degrees in quality and proportions in quantity or numbers. The distinguishing characteristic of the group, according to Hume, is that they all depend entirely on the ideas which we compare together. Tne example he gives is that of a triangle 2 whose three angles are equal to two right ones. And this presumably is at the same time an example of a relation of proportion in quantity or numbers. Needless to say, what cries out for explanation here, apart from the notion of comparison with which we shall deal later, is the phrase "depend entirely upon the ideas." Hume himself does not provide the explanation. Consequently, a certain amount of speculation becomes inevitable. One fairly plausible although, as we shall see, not entirely satisfactory interpretation of the phrase in question would associate it with a thesis concerning the reducibility of relations between exemplars of properties to relations between the properties themselves. Thus it may 32 be argued that the equality holding between the three angles of a triangle and two right angles is reducible to an equality holding between certain of their properties. The properties would be the 180° that each set of angles exemplifies. Indirect evidence for this interpretation is provided by Hume's account of the relations of contiguity and distance, species presumably of relations of time and place, which do not, according to him, depend upon the ideas wnich are compared together. Indeed, these relations may be changed by "an alteration of their place, without any change on the objects themselves or on their 3 ideas." "The place" in its turn "depends on a hundred 4 different accidents which cannot be foreseen by the mind." Leaving aside Hume's failure or refusal to draw a clear distinction here between ideas and objects which probably has to do with his belated realization that only the latter have places and are contiguous to or distant from one another, one notes his insistence that an object's place is not an essential property of the object. For his use of the word "accident" in the above-quoted passage has very little to do with its ordinary use and everything to do with its logical one where it is contrasted with "essential." Furthermore, the sentence immediately preceding the one containing that passage gives some indication of what Hume takes its logical use to be : A determinate property is an accidental one if loss of that property does not affect the object's identity or, as he would put it, the object itself. Nor is the accidental nature of the property anything but reinforced by its dependence logical or otherwise upon other accidental properties which like all such properties require an appeal to observation and induction in order to determine whether they are exemplified by that object. The loss of an essential property, on the other hand, would affect the object's identity because such properties are contained in the very definition of the object. And it suffices to understand the definition - Hume's foreseeing by the 33 7 mind comes in here - in order to determine that the property is exemplified by the object. How does this account provide indirect evidence for our interpretation of Hume? The answer is relatively straightforward. According to that interpretation, relations which depend entirely on the ideas which we compare together are tnose where relations between exemplars of properties are reducible to relations between...

In our critical review of Doing without Concepts, we argue that although the heterogeneity hypothesis (according to which exemplars, prototypes and theories are natural kinds that should replace ‘concept’) may end fruitless debates in the psychology of concepts, Edouard Machery did not anticipate one consequence of his suggestion: Definitions now acquire a new status as another one of the bodies of information replacing ‘concept’. In order to support our hypothesis, we invoke dual-process models to suggest that prototypes, exemplars and theories (...) are ‘Type 1’ concepts (automatic, implicit) and definitions ‘Type 2’ concepts (controlled, explicit). In the context of this argument, we suggest that one must better distinguish between Type 1 theories (e.g., Bayesian causal nets) and Type 2 theories (e.g., scientific) that explicitly control definitions.

The Half-Causation Method is a metaphysical-epistemic model for developing industrialised technological inventions. It consists of five phases of reasoning through which methodological success is achieved. The Method is named after its first phase, which consists of a methodological idealisation of the causal process, by pinpointing half of a possible causal relation while ignoring everything else. Following this, the Method prescribes how the reasoning should proceed, which ultimately constructs a complete and novel causal process. Each phase terminates with an epistemic justification (...) which the inventor (or inventors) can share with other knowers and have them deliberated and scrutinised. As such, the entire process of developing industrialised technological inventions, including the early stages which are traditionally regarded as mysterious can be understood as a sequence of epistemic justifications. In this paper, the Half-Causation Method is presented as a detailed practical prescription for future projects which aim to develop industrialised technological inventions. Throughout the paper two case studies from the recent history of technology are used as exemplars, namely: the invention of the microwave oven and the invention of the centrifugal vacuum cleaner. First, a definition of the ‘technological invention’ is proposed. Following that, the prescription is presented as fifteen methodological instructions: three instructions that repeat at each phase. The prescription is supplemented by a set-theoretic diagram. Although this is a philosophy paper, it is spoken directly to the scientists and engineers who aim to direct part of their research towards the development of inventions. (shrink)

This article examines some of the implications of technological optimism. I first contextualize, historically and culturally, some contemporary variants of techno-optimism in relation to the equally significant contemporary exemplars of techno-pessimism, skepticism and fatalism. I show that this techno-optimism is often instrumentalized in the sense that the optimistic outlook as such is believed to have some influence on the evolving state of affairs. The cogency of this assumption is scrutinized. I argue that in the absence of explicit probabilities, such optimism (...) presupposes some form of retro-causation, where the future is held to somehow have a retroactive effect on the past. This suggests that the underlying mechanism by which techno-optimism is supposed to be instrumental in bringing about the future is fundamentally superstitious. Such superstition, of course, goes against our common understanding of reason and rationality, for adopting rational expectations about the world requires that we avoid the emotional over-determination of our assessments. I show that applied reason is conceptually entangled with this superstitious optimism in the continued successes of technology. The article thus reveals a curious sense in which reason is intrinsically superstitious. I offer an evolutionary explanation for this, showing that the biological origins of reason will by nature tend to produce rational agents which are superstitiously bound to realism and causality, and thus implicitly optimistic about technology’s capacity to overcome contingency.

Many different, seemingly mutually exclusive, theories of categorization have been proposed in recent years. The most notable theories have been those based on prototypes, exemplars, and causal models. This chapter provides “representation theorems” for each of these theories in the framework of probabilistic graphical models. More specifically, it shows for each of these psychological theories that the categorization judgments predicted and explained by the theory can be wholly captured using probabilistic graphical models. In other words, probabilistic graphical models provide a (...) lingua franca for these disparate categorization theories, and so we can quite directly compare the different types of theories. These formal results are used to explain a variety of surprising empirical results, and to propose several novel theories of categorization. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:God’s Knowledge of the World: Medieval Theories of Divine Ideas from Bonaventure to Ockham by Carl A. VaterBenjamin R. DeSpainVATER, Carl A. God’s Knowledge of the World: Medieval Theories of Divine Ideas from Bonaventure to Ockham. Washington, D.C.: The Catholic University of America Press, 2022. xi + 294 pp. Cloth, $75.00Carl Vater skillfully blends historical and constructive concerns in his study of medieval theories of the divine ideas. (...) The book, first, makes a significant contribution to the body of scholarly resources on medieval philosophy by systematically mapping out the complex intellectual history of the divine ideas between the years 1250 and 1325. Throughout the work Vater displays a staggering command of the relevant literature, figures, and ideas from this period of philosophical development. Second, he provides a robust defense and promotion of John Duns Scotus’s theory of the divine ideas, which he regularly insists is the best theory. Through careful analysis of the often subtle differences in medieval articulations of the divine ideas to answer the questions of how God knows and produces creatures, Vater makes the case that Scotus avoided certain pitfalls in earlier theories that rely on a flawed understanding of relations influenced, principally, by Avicenna’s notion of essence.The book itself is divided into five parts with each systematically detailing a particular theory, beginning with the “imitability theory” represented by Thomas Aquinas, Henry of Ghent, and Bonaventure—the one figure, in Vater’s narrative, capable of escaping Scotus’s subsequent critiques. According to Vater, the imitability theory is defined by several notable characteristics, including that the divine ideas are “secondary objects of the divine intellect when it knows the divine essence,” that they perform both cognitive and causal roles, that they are relations, and that there are many of them. The “infinite intellect theory” critiques the imitability theory for depending on a notion of relations that is mistaken for supposing that relations can be known before the terms of the relation are themselves known. In this section, Vater examines the works of Peter John Olivi and his student Petrus de Trabibus. The third part considers what Vater calls the “objectum cognitum theory” developed by James of Viterbo. Here, according to Vater, we encounter the first signs, following Olivi and de Trabibus’s critique of the imitability theory, of the shift away from identifying the divine ideas with relations to defining them as creatures themselves. This shift culminates in the “creatura intellecta theory” introduced by Richard of Mediavilla, but it is not properly developed until Scotus, who concludes that “God knows relations because he knows possible creatures.” The section ends with an analysis of Scotus’s influence on the theories of early Thomists and Scotists, including John of Paris, Thomas of Sutton, and Henry of Harclary. In the fifth part, Vater turns to the “nominalist theory” of Peter Auriol and [End Page 373] William of Ockham. Although both Auriol and Ockham offer accounts of the divine ideas, these are, as Vater says, little more than nods to the Augustinian tradition that ultimately amount to a rejection of the divine ideas.Vater’s approach to these medieval theories has many strengths. By not only classifying the prominent theories during this period but also systematically organizing his interpretation of each respective author, he is able to create a comparative framework for assessing the central issues at play in the divine ideas, such as their status, definition, cognitive and causal roles, plurality and unity, exemplarity, and the question of nonexistent possibles, and he traces variations in each area to identify where change, development, and critique are actually occurring within this seventy-five years of intellectual history. He also is attentive to figures often overlooked in larger narrations of medieval philosophy, and he locates their contributions to the varied development of the divine ideas. More importantly, however, Vater is able to maintain coherence in his evaluation of these complex, intertwining layers of medieval philosophical reflection by constantly returning to the overarching theme of relations in the movement from identifying the divine ideas with relations to approaching them as creatures themselves. Vater is correct when he notes that the divine ideas form a... (shrink)

There is a traditional view of pain as a conscious phenomenon which satisfies the following two principles at least: Pain is essentially a belief- or cognition-independent sensation, given for consciousness in an immediate way, and pain′s unitary physical base is responsible for both its phenomenal or felt qualities and it′s functional, causal features. These are "The Raw Feels Principle" and "The Unity of Pain Principle" . Each is shown to be implausible. Evidence comes from recent pain research in a number (...) of dimensions. A further argument against The Unity of Pain Principle is constructed by analogy with facts about blindsight. The consequences of rejecting P or Q are examined in light of the traditional epistemological role of pain as exemplar of sensations thought to be foundational for knowledge, the prospects of a modularity theory of the pain system, recent accounts of pain among contemporary philosophers, a naturalist and realist conception of pain, and views about the status of Folk Psychology.

Abstract (for the combined three Parts) This paper presents the simplest known theory of processes involved in a person’s unconscious and conscious achievements such as intending, perceiving, reacting and thinking. The basic principle is that an individual has mental states which possess quantitative causal powers and are susceptible to influences from other mental states. Mental performance discriminates the present level of a situational feature from its level in an individually acquired, multiple featured norm (exemplar, template, standard). The effect on (...) output of a moderate disparity between input and norm is scaled in a universal unit of discrimination (Weber’s fraction), with the norm’s level being zero. When one process converts separate sources of input into an output, their discriminative distances from norm are summated. Distinct processes converging on an output combine their discriminations from norm orthogonally. An output may be influenced by the constructs of other outputs as well as by inputs. Descriptive performance is the influence of one category of input on a verbal output. Reasoning is minimally the effect of one verbal process on another. In deeper mental processing, the influence on a response comes from a response construct modulating a description: this process gives the meaning to an emotion or a motive. Descriptive modulation of stimulation corresponds to a bodily sensation or other conceptualized percept. When an output is explained solely by sources of input, that response to the stimulation may be mediated unconsciously. Development of a person within physical and communal environments embodies such mental causation within material causation and acculturates that mind to social causation. (shrink)

The Schrödinger equation for quantum mechanics, which is approachable in third-person description, takes for granted tenseless time that does not distinguish between different tenses such as past, present, and future. The time-reversal symmetry grounded upon tenseless time globally may, however, be broken once measurement in the form of exchanging indivisible quantum particles between the measured and the measuring intervenes. Measurement breaks tenseless time locally and distinguishes different tenses. Since measurement is about the material process of feeding and acting upon the (...) quantum resources already available from any material bodies to be measured internally, the agency of measurement is sought within the environment in the broadest sense. Most indicative of internal measurement of the environmental origin are chemical reactions in the reaction environment. Temporality naturalized in chemical reactions proceeding as being subjected to frequent interventions of internal measurement is approachable in second-person description because of the participation of multiple agents of measurement there. The use of second-person description is found in the appraisal of the material capacity of generating, distinguishing, and integrating different tenses. An essence of the temporality to be naturalized is within the genesis of different tenses. A most conspicuous exemplar of naturalized temporality is sought in the origins of life conceivable exclusively on the material ground. (shrink)

John Wilkins and Malte Ebach respond to the dismissal of classification as something we need not concern ourselves with because it is, as Ernest Rutherford suggested, mere ‘‘stamp collecting.’’ They contend that classification is neither derivative of explanation or of hypothesis-making but is necessarily prior and prerequisite to it. Classification comes first and causal explanations are dependent upon it. As such it is an important (but neglected) area of philosophical study. Wilkins and Ebach reject Norwood Russell Hanson’s thesis that classification (...) relies on observation that is theory-laden and deny the need for aetiological assumptions and historical reconstruction to justify its arrangement. What they offer instead is a significant (albeit controversial) contribution to the philosophical literature on classification, a pre-theoretic natural classification based on the observation of patterns in data of ready-made phenomena. Their notion of ready-made phenomena rests on a conception of tacit knowledge or know-how. This is evident in their distinction between strong Theory-dependence and na ̈ıve theory-dependence. Their small t-theory-dependence permits patterns of observation that facilitate know-how but does not rely on a domain-specific explanatory theory of their aetiology. Wilkins and Ebach suggest classification differs from theory building in that it is passive (whereas theory building is active). Classification is possible just because it does not require the sieve of theory to capture classes that are ‘‘handed to you by your cognitive dispositions and the data that you observe’’ (p. 18). Finding regularities sans-theory is just something we do and can do without any prior theory about the underlying causes or origins of the resultant regularities. Luke Howard’s classification of clouds serves as an exemplar of a passive, theory-free classification system and the periodic table and the DSM help to illustrate this type of non-aetiological patterning. A recurrent theme is the nature of naturalness. For Wilkins and Ebach, the conception of naturalness is not one that is based on the generation or discovery of natural kind categories popular in both the traditional metaphysics of Mill and Wittgenstein as well as updated notions within philosophy of biology such as Boyd’s Homeostatic Property Cluster kinds. Instead, Wilkins and Ebach define the naturalness of classification as the falling into hierarchical patterns, aligning the search for natural arrangement with the aim of systematics, and as something that is grounded in a cognitive task or activity. However, they leave the question of realism v. antirealism open. ‘‘In natural classification...we must have real relations no matter how we might interpret ‘real’’’ (p. 70). There is tension with regard to their ontological commitments as they vacillate between constructive, operationalist, and realist approaches. Wilkins and Ebach initially define real as that which is causal and important (pp. 70–71), and later as that which ‘‘depends in no way upon a mind or observer’’ (p. 122). This makes their claim that there was ‘‘no real theory involved [in the pre-Darwinian classifications of Jussieu and Adanson]’’ (p. 64) difficult to interpret. Cont’d……. (shrink)
