In the past decades, reductionism has dominated both research directions and funding policies in clinical psychology and psychiatry. The intense search for the biological basis of mental disorders, however, has not resulted in conclusive reductionist explanations of psychopathology. Recently, network models have been proposed as an alternative framework for the analysis of mental disorders, in which mental disorders arise from the causal interplay between symptoms. In this target article, we show that this conceptualization can help explain why reductionist approaches in (...) psychiatry and clinical psychology are on the wrong track. First, symptom networks preclude the identification of a common cause of symptomatology with a neurobiological condition; in symptom networks, there is no such common cause. Second, symptom network relations depend on the content of mental states and, as such, feature intentionality. Third, the strength of network relations is highly likely to depend partially on cultural and historical contexts as well as external mechanisms in the environment. Taken together, these properties suggest that, if mental disorders are indeed networks of causally related symptoms, reductionist accounts cannot achieve the level of success associated with reductionist disease models in modern medicine. As an alternative strategy, we propose to interpret network structures in terms of D. C. Dennett's (1987) notion ofreal patterns, and suggest that, instead of being reducible to a biological basis, mental disorders feature biological and psychological factors that are deeply intertwined in feedback loops. This suggests that neither psychological nor biological levels can claim causal or explanatory priority, and that a holistic research strategy is necessary for progress in the study of mental disorders.

Is it possible to measure psychological attributes like intelligence, personality and attitudes and if so, how does that work? What does the term 'measurement' mean in a psychological context? This fascinating and timely book discusses these questions and investigates the possible answers that can be given response. Denny Borsboom provides an in-depth treatment of the philosophical foundations of widely used measurement models in psychology. The theoretical status of classical test theory, latent variable theory and positioned in terms of (...) the underlying philosophy of science. Special attention is devoted to the central concept of test validity and future directions to improve the theory and practice of psychological measurement are outlined. (shrink)

We argue that neural networks for semantic cognition, as proposed by Rogers & McClelland (R&M), do not acquire semantics and therefore cannot be the basis for a theory of semantic cognition. The reason is that the neural networks simply perform statistical categorization procedures, and these do not require any semantics for their successful operation. We conclude that this has severe consequences for the semantic cognition views of R&M.

The literature on thought experiments has been mainly concernedwith thought experiments that are directed at a theory, be it in aconstructive or a destructive manner. This has led somephilosophers to argue that all thought experiments can beformulated as arguments. The aim of this paper is to drawattention to a type of thought experiment that is not directed ata theory, but fulfills a specific function within a theory. Suchthought experiments are referred to as functional thoughtexperiments, and they are routinely used in (...) applied statistics. An example is given from frequentist statistics, where a thoughtexperiment is required to establish the probability space. It isconcluded that (a) not all thought experiments can be formulated asarguments, and (b) the role of thought experiments is more generaland more important to scientific reasoning than has previouslybeen recognized.

An effective restructuring of the social sciences around the evolutionary model requires that evolutionary theory has explanatory power with respect to the spread of cultural traits: The causal mechanisms involved should be structurally analogous to those of biological evolution. I argue that this is implausible because phenotypical consequences of cultural traits are not causally relevant to their chances of “survival.” (Published Online November 9 2006).

We address the commentaries on our target article in terms of four major themes. First, we note that virtually all commentators agree that mental disorders are not brain disorders in the common interpretation of these terms, and establish the consensus that explanatory reductionism is not a viable thesis. Second, we address criticisms to the effect that our article was misdirected or aimed at a straw man; we argue that this is unlikely, given the widespread communication of reductionist slogans in psychopathology (...) research and society. Third, we tackle the question of whether intentionality, extended systems, and multiple realizability are as problematic as claimed in the target article, and we present a number of nuances and extensions with respect to our article. Fourth, we discuss the question of how the network approach should incorporate biological factors, given that wholesale reductionism is an unlikely option. (shrink)

When it originated in the late 19th century, psychometrics was a field with both a scientific and a social mission: psychometrics provided new methods for research into individual differences, and at the same time, these psychometric instruments were considered a means to create a new social order. In contrast, contemporary psychometrics - due to its highly technical nature and its limited involvement in substantive psychological research - has created the impression of being a value-free discipline. In this article, we develop (...) a contrasting characterization of contemporary psychometrics as a value-laden discipline. We expose four such values: that individual differences are quantitative (rather than qualitative), that measurement should be objective in a specific sense, that test items should be fair, and that utility of a model is more important than its truth. Our goal is not to criticize psychometrics for employing these values, but rather to bring them into the open and to show that these values are not inevitable and are in need of systematic evaluation.

Jones & Love (J&L) suggest that Bayesian approaches to the explanation of human behavior should be constrained by mechanistic theories. We argue that their proposal misconstrues the relation between process models, such as the Bayesian model, and mechanisms. While mechanistic theories can answer specific issues that arise from the study of processes, one cannot expect them to provide constraints in general.

Cognition played a pivotal role in the acceleration of technological innovation during the Industrial Revolution. Growing affluence may have provided favourable environmental conditions for a boost in cognition, enabling individuals to tackle more complex problems. Dynamical systems thinking may provide useful tools to describe sudden transitions like the Industrial Revolution, by modelling the recursive feedback between psychology and environment.

According to Oude Maatman (2020), our recent suggestion (Borsboom et al., 2019) that symptom networks are irreducible because they rely on folk psychological descriptions, threatens to undermine the main achievements of the network approach. In this article, we take up Oude Maatman’s challenge and develop an argument showing in what sense folk psychological concepts describe features of reality, and what it means to say that folk psychology is a causal language.

Asay (2018) criticizes our contention that psychologists do best to adhere to a substantive theory of correspondence truth. He argues that deflationary theory can serve the same purposes as correspondence theory. In the present article we argue that (a) scientific realism, broadly construed, requires a version of correspondence theory and (b) contrary to Asay’s suggestion, correspondence theory does have important additional resources over deflationary accounts in its ability to support generalizations over classes of true sentences.

The pivotal problem of comorbidity research lies in the psychometric foundation it rests on, that is, latent variable theory, in which a mental disorder is viewed as a latent variable that causes a constellation of symptoms. From this perspective, comorbidity is a (bi)directional relationship between multiple latent variables. We argue that such a latent variable perspective encounters serious problems in the study of comorbidity, and offer a radically different conceptualization in terms of a network approach, where comorbidity is hypothesized to (...) arise from direct relations between symptoms of multiple disorders. We propose a method to visualize comorbidity networks and, based on an empirical network for major depression and generalized anxiety, we argue that this approach generates realistic hypotheses about pathways to comorbidity, overlapping symptoms, and diagnostic boundaries, that are not naturally accommodated by latent variable models: Some pathways to comorbidity through the symptom space are more likely than others; those pathways generally have the same direction (i.e., from symptoms of one disorder to symptoms of the other); overlapping symptoms play an important role in comorbidity; and boundaries between diagnostic categories are necessarily fuzzy.

The network approach to psychopathology posits that mental disorders can be conceptualized and studied as causal systems of mutually reinforcing symptoms. This approach, first posited in 2008, has grown substantially over the past decade and is now a full-fledged area of psychiatric research. In this article, we provide an overview and critical analysis of 363 articles produced in the first decade of this research program, with a focus on key theoretical, methodological, and empirical contributions. In addition, we turn our attention (...) to the next decade of the network approach and propose critical avenues for future research in each of these domains. We argue that this program of research will be best served by working toward two overarching aims: (a) the identification of robust empirical phenomena and (b) the development of formal theories that can explain those phenomena. We recommend specific steps forward within this broad framework and argue that these steps are necessary if the network approach is to develop into a progressive program of research capable of producing a cumulative body of knowledge about how specific mental disorders operate as causal systems.

Lindquist et al. present a strong case for a constructionist account of emotion. First, we elaborate on the ramifications that a constructionist account of emotions might have for psychiatric disorders with emotional disturbances as core elements. Second, we reflect on similarities between Lindquist et al.'s model and recent attempts at formulating psychiatric disorders as networks of causally related symptoms.

The majority of commentators agree on one thing: Our network approach might be the prime candidate for offering a new perspective on the origins of mental disorders. In our response, we elaborate on refinements (e.g., cognitive and genetic levels) and extensions (e.g., to Axis II disorders) of the network model, as well as discuss ways to test its validity.

What is intellectual humility? In this essay, we aim to answer this question by assessing several contemporary accounts of intellectual humility, developing our own account, offering two reasons for our account, and meeting two objections and solving one puzzle.

The compatibility of evolution with Aristotelian-Thomistic metaphysics is defended in response to Fr. Michal Chaberek’s thesis of incompatibility. The motivation and structure of Darwin’s theory are reviewed, including the roles of secondary causality, randomness and necessity. “Randomness” is an analogous term whose evolutionary use, while challenging, is fully compatible with theism. Evolution’s necessity derives from the laws of nature, which are intentional realities, the vehicle of divine providence. Methodological analysis shows that metaphysics lacks the evidentiary basis to judge biological theories. (...) Species are entia rationis whose immutability does not conflict with the evolutionary succession of biological populations. While Darwin’s theory was unknown to Aquinas, he endorses the possibility of new species immanent in the initial state of the universe, nor does his understanding of exemplar ideas offer ground for objection. Finally, five arguments given by Fr. Chaberek are answered. (shrink)

The central task of this dissertation is to develop a new interpretation of Leibniz's famous claim that there are no purely extrinsic denominations . Though Leibniz regarded NPE as one of his most important doctrines, he nowhere offers an explicit statement as to what he meant by it. One interpretation of NPE, which enjoys a modest consensus among interpreters, is that all extrinsic denominations reduce to intrinsic denominations. According to the reductionist view, things only have intrinsic denominations as properties; extrinsic (...) denominations are not genuine properties of things. Critics of reductionism have argued that the textual case for it is inconclusive at best, and I share this assessment with them. However, in my opinion, a satisfactory non-reductionist understanding of NPE has not been offered. The goal of my dissertation is to provide such a non-reductionist account. I contend that NPE, far from being a claim of the reducibility of extrinsic denominations, is actually an assertion that extrinsic denominations are genuine properties of the things they denominate. ;To establish my reading of NPE, I examine a line of textual evidence to which interpreters have paid little attention: the way Leibniz argues for NPE. In some passages Leibniz derives NPE from his predicate-in-subject principle of truth. In others, he employs his doctrine of the interconnection of all things to reach NPE. Elsewhere, he bases NPE on the principle of the identity of indiscernibles. Though, as mentioned, Leibniz never explicitly defines NPE, he does have much to say by way of explicit definition of each of these three principles. A consideration of what version of NPE could plausibly be drawn from them is thus a revealing way to proceed. In the case of each argument, I show that my interpretation of NPE is the conclusion naturally suggested by the given principle, while the reductionist version of NPE forms only an awkward, textually implausible fit with it. The result of the examination is an original and serious critique of the reductionist reading of NPE, as well as the development of a far more plausible understanding of that claim. (shrink)

ABSTRACT David Hume’s attacks on causality and induction along with his celebrated is-ought dichotomy dealt a blow to the human mind from which Western civilization has never fully recovered. Centuries after his death, Hume remains immensely popular among academic philosophers, which only bolsters the myth that his skeptical arguments are unanswerable. In fact, his arguments are seriously flawed. The first part of this paper clarifies the basics of Hume’s philosophy, focusing on the epistemology in the Treatise and Enquiry. The second (...) part exposes the mistaken premises and assumptions in Hume’s arguments, demonstrating how Objectivism redeems the validity of human knowledge. (shrink)

Philosophical naturalists claim macroevolution shows order emerging by pure chance. This claim is incompatible with accepted physical and biological principles. The present state of the universe is implicit in its initial state and the laws ofnature. Logical principles essential to science require these laws to be maintained by a self-conserving reality identifiable as God. Further, the laws share a common dynamic with human committed intentions. Both are logical propagators seen to the intentional by theists and naturalists alike. Mechanism and teleology (...) project a single reality into different conceptual spaces. Statistically, evolution is only possible given predefined goals. For fitness to be explanatory, it must be prior to survival events, entailing immanent goals verified by convergent evolution, toolkit genes, and evolutionary stasis. Aristotle's falsifiable claims for teleology are confirmed by evolution. Evolution is not random, but fully intentional, evidencing mind in nature. (shrink)

This paper extends several themes from recent work on norms of assertion. It does as much by applying those themes to the speech act of asking. In particular, it argues for the view that there is a species of asking which is governed by a certain norm, a norm to the effect that one should ask a question only if one doesn’t know its answer.

The current research investigates how religiosity can influence unethicality in a consumption context. In particular, considering the link between extrinsic religious orientations and unethicality, this research clarifies why and when extrinsic religiosity leads to unethical decisions. Across two studies, findings show that ethnocentrism is both a mediator and a moderator of the effects of extrinsic religiosity on consumers’ ethical judgments. This is because extrinsic religiosity leads to ethnocentrism, and in-group loyalty manifested through ethnocentrism increases support for unethical consumer actions, thus (...) establishing ethnocentrism as a mediator. At the same time, different levels of ethnocentrism can also influence how extrinsic religiosity leads to supporting unethical consumption via self-righteousness, thus establishing ethnocentrism as a moderator. The findings from this research have significant implications for diverse stakeholders who have an interest in religiosity and consumer behavior. (shrink)

Various studies on the impact of religiousness on consumer ethics have produced mixed results and suggested further clarification on the issue. Therefore, this article examines the effect of religiousness, materialism, and long-term orientation on consumer ethics in Indonesia. The results from 356 respondents in Indonesia, the largest Muslim population in the world, showed that intrinsic religiousness positively affected consumer ethics, while extrinsic social religiousness negatively affected consumer ethics. However, extrinsic personal religiousness did not affect consumer ethical beliefs dimensions. Unlike other (...) studies in developed countries, materialism and long-term orientation influenced only a few of the consumer ethical beliefs dimensions in this study. To date, the study is one of the first empirical studies to explore the impact of religiousness on consumer ethics in Indonesia. The study contributes to the debate on the impact of religiousness on consumer ethics and can assist managers and public policymakers in their effort to mitigate unethical consumer activities in Indonesia.

The story of the greatest of all philosophical friendships—and how it influenced modern thought David Hume is widely regarded as the most important philosopher ever to write in English, but during his lifetime he was attacked as “the Great Infidel” for his skeptical religious views and deemed unfit to teach the young. In contrast, Adam Smith was a revered professor of moral philosophy, and is now often hailed as the founding father of capitalism. Remarkably, the two were best friends for (...) most of their adult lives, sharing what Dennis Rasmussen calls the greatest of all philosophical friendships. The Infidel and the Professor is the first book to tell the fascinating story of the friendship of these towering Enlightenment thinkers—and how it influenced their world-changing ideas. The book follows Hume and Smith’s relationship from their first meeting in 1749 until Hume’s death in 1776. It describes how they commented on each other’s writings, supported each other’s careers and literary ambitions, and advised each other on personal matters, most notably after Hume’s quarrel with Jean-Jacques Rousseau. Members of a vibrant intellectual scene in Enlightenment Scotland, Hume and Smith made many of the same friends, joined the same clubs, and were interested in many of the same subjects well beyond philosophy and economics—from psychology and history to politics and Britain’s conflict with the American colonies. The book reveals that Smith’s private religious views were considerably closer to Hume’s public ones than is usually believed. It also shows that Hume contributed more to economics—and Smith contributed more to philosophy—than is generally recognized. Vividly written, The Infidel and the Professor is a compelling account of a great friendship that had great consequences for modern thought. (shrink)

Recent decades have seen a revived interest in super-substantivalism, the idea that spacetime is the only fundamental substance and matter some kind of aspect, property or consequence of spacetime structure. However, the metaphysical debate so far has misidentified a particular variant of super-substantivalism with the position per se. I distinguish between a super-substantival core commitment and different ways of fleshing it out. I then investigate how general relativity and alternative spacetime theories square with the different variants of super-substantivalism.

In The Elm and the Expert, Jerry Fodor tries to reconcile three philosophical positions he is presently committed to: a computational theory of mind, intentional realism and a denotational theory of meaning. One problem he faces is this: a denotational semantics, according to which the meaning of a singular term like a name is exhausted by its referent, seems to rule out there being true intentional generalizations, or generalizations which advert to the contents of a subject's mental states. That there (...) are such true generalizations is a major element in Fodor's intentional realism. Accordingly, Fodor is forced to find a way of dissolving this apparent incompatibility. This paper looks at his attempts to do so and concludes that they fail. (shrink)

This paper argues that questions can be bullshit. First it explores some shallowly interrogative ways in which that can happen. Then it shows how questions can also be bullshit in a way that’s more deeply interrogative.

I argue that, contrary to folklore, Einstein never really cared for geometrizing the gravitational or the electromagnetic field; indeed, he thought that the very statement that General Relativity geometrizes gravity "is not saying anything at all". Instead, I shall show that Einstein saw the "unification" of inertia and gravity as one of the major achievements of General Relativity. Interestingly, Einstein did not locate this unification in the field equations but in his interpretation of the geodesic equation, the law of motion (...) of test particles. (shrink)

The Aristotelian dictum that desire is the starting point of practical reasoning that ends in action can of course be denied. Its denial is a commonplace of moral theory in the tradition of Kant. But in this essay I am concerned with that issue only indirectly. I shall not contend that rational action always or necessarily does involve desire as its starting point; nor shall I deny it. My question concerns instead the possibility of its ever beginning in desire. For (...) there is a question whether it is even possible for reasoning to begin in desire, a question arising from the nature of desire and its objects, which to my knowledge has not been articulated. If we can see how desire can provide the arche of action, then we can consider later, and from that vantage point, whether it is necessary that it should do so. It will, I think, be possible eventually to argue that if practical reasoning has the character it must have, if it can begin in desire, then its starting point can be nothing but desire. (shrink)

Abstract:This study explores a phenomenon that has been shown to adversely affect managers’ decisions—competitive irrationality. Managers are irrationally competitive in their decisions when they focus on damaging the profits of competitors, rather than improving their own profit performance. Studies by Armstrong and Collopy (1996) and Griffith and Rust (1997) suggest that the phenomenon is common but not universal. We examine the question of why some individuals exhibit competitive irrationality when making decisions, while others do not by focusing on four aspects (...) of moral philosophy—deontological orientation, cognitive moral development, idealism, and relativism. Results suggest that individuals high in deontological orientation, high in cognitive moral development, high in idealism, and low in relativism will be less competitively irrational than those who are not.

I discuss the relationship between different versions of the equivalence principle in general relativity, among them Einstein's equivalence principle, the weak equivalence principle, and the strong equivalence principle. I show that Einstein's version of the equivalence principle is intimately linked to his idea that in GR gravity and inertia are unified to a single field, quite like the electric and magnetic field had been unified in special relativistic electrodynamics. At the same time, what is now often called the strong equivalence (...) principle, related to the local validity of special relativity, can also be found in Einstein's writings, albeit by a different name and clearly separated from what he calls the equivalence principle. I discuss both the development of Einstein's thoughts on the different versions of the equivalence principle, their relationship to the relativity principle, as well as later reflections and variants proposed.

Adam Smith is popularly regarded as the ideological forefather of laissez-faire capitalism, while Rousseau is seen as the passionate advocate of the life of virtue in small, harmonious communities and as a sharp critic of the ills of commercial society. But, in fact, Smith had many of the same worries about commercial society that Rousseau did and was strongly influenced by his critique. In this first book-length comparative study of these leading eighteenth-century thinkers, Dennis Rasmussen highlights Smith’s sympathy with Rousseau’s (...) concerns and analyzes in depth the ways in which Smith crafted his arguments to defend commercial society against these charges. These arguments, Rasmussen emphasizes, were pragmatic in nature, not ideological: it was Smith’s view that, all things considered, commercial society offered more benefits than the alternatives. Just because of this pragmatic orientation, Smith’s approach can be useful to us in assessing the pros and cons of commercial society today and thus contributes to a debate that is too much dominated by both dogmatic critics and doctrinaire champions of our modern commercial society.

The problem of foreknowledge and freedom presents a challenge to the defender of traditional Western theism. Nelson Pike has argued that the existence of an essentially omniscient God who possesses foreknowledge is incompatible with human freedom. Pike's opponents in this matter, among whom is Alvin Plantinga, argue that no incompatibility has yet been shown. I shall develop the view that neither Pike nor his opponents have conclusively settled the question whether foreknowledge and freedom are compatible. Furthermore there is a reason (...) why the issue has not been, and may never be, conclusively settled: it is an inherently paradoxical issue. To aid in demonstrating this point I shall discuss a modified version of a paradox that has come to be known as Newcomb's Problem. (shrink)
