This edited volume presents new lines of research dealing with the language of thought and its philosophical implications in the time of Ockham. It features more than 20 essays that also serve as a tribute to the ground-breaking work of a leading expert in late medieval philosophy: Claude Panaccio. Coverage addresses topics in the philosophy of mind and cognition, concepts, logic and language, action theory, and more. A distinctive feature of this work is that it brings together contributions in both (...) French and English, the two major research languages today on the main theme in question. It unites the most renowned specialists in the field as well as many of Claude Panaccio’s former students who have engaged with his work over the years. In furthering this dialogue, the essays render key topics in fourteenth-century thought accessible to the contemporary philosophical community without being anachronistic or insensitive to the particularities of the medieval context. As a result, this book will appeal to a general population of philosophers and historians of philosophy with an interest in logic, philosophy of language, philosophy of mind, and metaphysics.

In William Ockham on Metaphysics, Jenny E. Pelletier gives an account of Ockham's concept of metaphysics as the science of being and God as it emerges sporadically throughout his philosophical and theological work.

This slim volume contains a collection of eight essays that were originally given as lectures in 2002 under the aegis of the Society for Medieval Logic and Metaphysics. It is the second in a series of nine volumes published thus far, on subjects such as mental representation, free will, the ontology of individuation, the conceivability of God, skepticism, and nominalism. The title of the present volume is slightly misleading. Only the first two contributions are devoted to medieval treatments of the (...) ten Aristotelian categories (substance, quantity, relation, quality, etc.). The remaining six are about “what is beyond.” One might assume this is intended to refer to God or to the transcendentals, i.e. being, one .. (shrink)

This book offers a collection of contributions on medieval, early modern, and contemporary perspectives on social ontology. Since the 1990s, social ontology has emerged as a vibrant research area in contemporary analytical philosophy. Questions concerning the nature and properties of social groups, institutions, facts, and objects like money and marriage, have been thoroughly discussed. However, the historical perspective has been largely neglected. One of the central aims of this volume is to show that relevant views on social ontology can be (...) found in medieval and early modern philosophy (ca. 1200-1700 C.E.), when, for example, the ontological status of money, law, and the sacraments was hotly debated. We see, furthermore, diverging positions between Aristotelian-inspired authors, who resort to a more naturalistic view of the emergence of the social realm, and authors like Olivi and Ockham, who emphasize the role of human free will and contractualist agreements. This book is the very first to address historical and contemporary social ontologies. Both historians of philosophy and philosophers will benefit from this juxtaposition, which fosters a better understanding of historical positions and approaches by using today’s conceptual and analytical tools, and allows the contemporary debate to gain new perspectives by confronting its own medieval and early modern history.

People frequently gesture when a word is on the tip of their tongue (TOT), yet research is mixed as to whether and why gesture aids lexical retrieval. We tested three accounts: the lexical retrieval hypothesis, which predicts that semantically related gestures facilitate successful lexical retrieval; the cognitive load account, which predicts that matching gestures facilitate lexical retrieval only when retrieval is hard, as in the case of a TOT; and the motor movement account, which predicts that any motor movements should (...) support lexical retrieval. In Experiment 1 (a between‐subjects study; N = 90), gesture inhibition, but not neck inhibition, affected TOT resolution but not overall lexical retrieval; participants in the gesture‐inhibited condition resolved fewer TOTs than participants who were allowed to gesture. When participants could gesture, they produced more representational gestures during resolved than unresolved TOTs, a pattern not observed for meaningless motor movements (e.g., beats). However, the effect of gesture inhibition on TOT resolution was not uniform; some participants resolved many TOTs, while others struggled. In Experiment 2 (a within‐subjects study; N = 34), the effect of gesture inhibition was traced to individual differences in verbal, not spatial short‐term memory (STM) span; those with weaker verbal STM resolved fewer TOTs when unable to gesture. This relationship between verbal STM and TOT resolution was not observed when participants were allowed to gesture. Taken together, these results fit the cognitive load account; when lexical retrieval is hard, gesture effectively reduces the cognitive load of TOT resolution for those who find the task especially taxing.

This study investigates the determinants of paternal investment by birth fathers and stepfathers. Inclusive fitness theory predicts higher parental investment in birth children than stepchildren, and this has consistently been found in previous studies. Here we investigate whether paternal investment varies with childhood co-residence duration and differs between stepfathers and divorced birth fathers by comparing the investment of (1) stepfathers, (2) birth fathers who are separated from the child’s mother, and (3) birth fathers who still are in a relationship with (...) her. Path analysis was conducted using cross-sectional data from adolescents and younger adults (aged 17–19, 27–29, and 37–39 years) from the German Family Panel (pairfam), collected in 2010–2011 (_n_ = 8326). As proxies of paternal investment, we used financial and practical help, emotional support, intimacy, and emotional closeness, as reported by the children. We found that birth fathers who were still in a relationship with the mother invested the most, and stepfathers invested the least. Furthermore, the investment of both separated fathers and stepfathers increased with the duration of co-residence with the child. However, in the case of financial help and intimacy, the effect of childhood co-residence duration was stronger in stepfathers than in separated fathers. Our findings support inclusive fitness theory and mating effort theory in explaining social behavior and family dynamics in this population. Furthermore, social environment, such as childhood co-residence was associated with paternal investment. (shrink)

“Ockham never wrote a commentary on Aristotle’s Metaphysics,” Jenny Pelletier tells us at the beginning of this monograph, “but the absence of such a commentary does not allow us to infer that he was uninterested in or skeptical of metaphysics” (1–2). Her central contention is that Ockham had a robust conception of metaphysics as a distinct branch of scientific knowledge concerning being and God. It is an argument worth making insofar as many scholars in recent years have held (...) that Ockham lacks a metaphysics or rejects the possibility of one. In opposing these claims, Pelletier also has much to say about what Ockham’s metaphysics includes and how it relates to other sciences. As the study of being, it considers .. (shrink)

Towards the end of Aline Medeiros Ramos’s study of John Buridan on craft as an intellectual virtue, she mentions William Ockham in passing and points towards his conception of craft. In this paper, I take up her implicit invitation to explore that conception. I begin by reconstructing Ockham’s notion of craft, and then proceed to discuss three consequences of that conception: the moral neutrality of craft, the role of deliberation in craftwork, and the epistemic status of craft and the craftworker. (...) I conclude by summarizing a number of issues that Buridan, according to Medeiros Ramos, finds it important to discuss, and which are noticeably absent from Ockham’s considerations. (shrink)

Given his known predilection for ontological parsimony, Ockham’s ontology of artifacts is unsurprisingly reductionist: artifacts are nothing over and above their existing and appropriately ordered parts. However, the case of artifacts is notable in that they are real objects that human artisans produce by bringing about a real change: they spatially rearrange existing natural thing(s) or their parts for the sake of some end. This article argues that the human contribution to the nature and production of artifacts is two-fold: (1) (...) the artisan’s cognitive grasp of her expertise and her decision to deploy that expertise are the two efficient causes necessary to explain the existence of an artifact, and (2) the purpose that the artisan had in mind when she decided to make an artifact fixes the function(s) of the artifact such that an artisan’s purpose is the final cause necessary to explain what an artifact is. Artifacts indeed exist, owing what they are and that they are to intelligent and volitional human activity, which Ockham never denies. The article submits that a myopic focus on Ockham’s indisputable reductionism does not exhaust what is metaphysically interesting and relevant about artifacts. (shrink)

ABSTRACT This paper reconstructs William of Ockham's (c. 1287–1347) account of the ontology of social groups. Across his writings, Ockham mentions kingdoms, religious orders, crowds, people, armies, and corporations. Using the political community as a case-study against the background of Ockham’s metaphysics of parts and wholes, it is argued that at least some social groups are identical to a plurality of many human beings who have decided to order themselves with respect to another in some particular way. In this regard, (...) a social group is a structured aggregate that is nothing over and above its existing and ordered parts, and, at least in the case of the political community, is like an artefact inasmuch as it is partly dependent on the volitional acts of its members to exist at all.

It has long been acknowledged that one of the most original aspects of Ockham’s account of knowledge is his contention that bodies of scientific knowledge are aggregates but without much explanation as to why he holds this view. In this chapter, I argue that a plausible philosophical motivation lies in the inner structure of his mental ontology, namely, in the intellect’s habits, acts, and their objects, which are the true and necessary principles and conclusions of demonstrations. Ockham upholds what I (...) call a “Principle of Object-Act-Habit-Specification,” according to which kinds of habits and their acts are determined by the objects they grasp. This principle entails that if a body of scientific knowledge contains two or more sentences, it can only have aggregate unity. Furthermore, I look at the logical and determinate orders that gather together the sentences of various aggregate bodies of scientific knowledge. (shrink)

In one of his Quodlibeta, William of Ockham entertains two concepts of God, one theological and the other philosophical. He argues that conclusions involving a theological concept of God are believable and can only be established in theology where recourse to faith is permissible. By contrast, conclusions involving a philosophical concept of God are knowable and can be proved in philosophy and theology. The source of these two concepts lies in the Sentences commentary of his confrère Walter Chatton,1 who explores (...) how different descriptions of God affect the provability of theological conclusions about God. Chatton himself is reacting to Ockham’s earlier Sentences commentary where Ockham suggests that a... (shrink)

In this introduction, we briefly introduce the concept of social ontology, a fertile sub-field of contemporary analytic metaphysics, and present the motivation for the present volume, which is largely though not exclusively historical in scope. We explain that philosophers in the ancient, medieval, and early modern world, with an emphasis on the medieval tradition, likewise took up questions and issues that are now discussed by philosophers working in social ontology. We then present the contents of the volume and suggest further (...) lines of research. (shrink)

In this short but dense monograph, Roques sets out to fill a significant lacuna in the literature on William of Ockham's logic, epistemology, and metaphysics: his theory of real definitions. Remarkably, the subject has received little attention, given that nominal definitions, specifically in connection to complex connotative concepts in mental language and their role in Ockham's ontological reductionism, have been a central focus since the early 1980s. One reason for this oversight may be the historical association between real definitions and (...) the realist view that essences are universal entities. Ockham, a resemblance nominalist, holds that all essences are individual entities; this does not, as Roques's present... (shrink)

Human engagement with imaginary worlds pervades history (e.g., Paleolithic cave paintings) and development (e.g., 18-month-olds pretend). In providing a safe environment, separate from the real world, fiction offers the opportunity for simulated exploration regardless of external circumstances. Thus, engagement with imaginary worlds in fiction may afford individuals opportunities to reap benefits and transfer these benefits back to the real world.

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

I develop a theory of counterfactuals about relative computability, i.e. counterfactuals such as 'If the validity problem were algorithmically decidable, then the halting problem would also be algorithmically decidable,' which is true, and 'If the validity problem were algorithmically decidable, then arithmetical truth would also be algorithmically decidable,' which is false. These counterfactuals are counterpossibles, i.e. they have metaphysically impossible antecedents. They thus pose a challenge to the orthodoxy about counterfactuals, which would treat them as uniformly true. What’s more, I (...) argue that these counterpossibles don’t just appear in the periphery of relative computability theory but instead they play an ineliminable role in the development of the theory. Finally, I present and discuss a model theory for these counterfactuals that is a straightforward extension of the familiar comparative similarity models. (shrink)

Resilience factors have been suggested as key mechanisms in the relation between symptoms and disability among individuals with chronic pain. However, there is a need to better operationalize resilience and to empirically evaluate its role and function. The present study examined psychological flexibility as a resilience factor in relation to symptoms and functioning among 252 adults with chronic pain applying for participation in a digital ACT-based self-help treatment. Participants completed measures of symptoms (pain intensity, anxiety), functioning (pain interference, depression), as (...) well as the hypothesized resilience factor psychological flexibility (measured as avoidance, value obstruction, and value progress). As expected, symptoms, functioning and resilience factors were significantly associated. Hierarchical linear regression analyses showed that psychological flexibility significantly contributed to the prediction of pain interference and depression when adjusting for age, pain and anxiety. Also, participants with low levels of psychological flexibility were more likely to be on sick leave. Furthermore, a series of multiple mediation analyses showed that psychological flexibility (avoidance, value obstruction, value progress) had a significant indirect effect on the relationship between symptoms and functioning. Avoidance was consistently shown to contribute to the indirect effect. Results support previous findings and suggest the importance of psychological flexibility as a resilience factor among individuals with chronic pain and anxiety. (shrink)

Recent research has begun to explore individual differences in statistical learning, and how those differences may be related to other cognitive abilities, particularly their effects on language learning. In this research, we explored a different type of relationship between language learning and statistical learning: the possibility that learning a new language may also influence statistical learning by changing the regularities to which learners are sensitive. We tested two groups of participants, Mandarin Learners and Naïve Controls, at two time points, 6 (...) months apart. At each time point, participants performed two different statistical learning tasks: an artificial tonal language statistical learning task and a visual statistical learning task. Only the Mandarin-learning group showed significant improvement on the linguistic task, whereas both groups improved equally on the visual task. These results support the view that there are multiple influences on statistical learning. Domain-relevant experiences may affect the regularities that learners can discover when presented with novel stimuli. (shrink)

Accurate perception of an individual’s identity and emotion derived from their actions and behavior is essential for successful social functioning. Here we determined the role of identity in the representation of emotional whole-body actions using visual adaptation paradigms. Participants adapted to actors performing different whole-body actions in a happy and sad fashion. Following adaptation subsequent neutral actions appeared to convey the opposite emotion. We demonstrate two different emotional action aftereffects showing distinctive adaptation characteristics. For one short-lived aftereffect, adaptation to the (...) emotion expressed by an individual resulted in biases in the perception of the expression of emotion by other individuals, indicating an identity-independent representation of emotional actions. A second, longer lasting, aftereffect was observed where adaptation to the emotion expressed by an individual resulted in longer-term biases in the perception of the expressions of emotion only by the same individual; this indicated an additional identity-dependent representation of emotional actions. Together, the presence of these two aftereffects indicates the existence of two mechanisms for coding emotional actions, only one of which takes into account the actor’s identity. The results that we observe might parallel processing of emotion from face and voice. (shrink)

What am I? There are a number of possible answers: I am a person, a mind, a human animal, a soul, part of a human being (e.g., a brain), I do not exist, and even more. Philosophers have been asking this for thousands of years and were not satisfied. In the contemporary analytic tradition, philosophers are attracted to a naturalistic, scientific ontology hence a materialistic personal ontology that matches the huge success in scientific discoveries. They think that we are material (...) objects. However, their views do not match our intuition about some cases regarding our survival. Also, the possibility of an afterlife is eliminated. In my thesis, I explain the shortcomings of current philosophical theories, and develop a better account. I propose the Conscious Subject View, according to which (1) I am a subject of experience, a mental entity whose essential property is to be conscious, and (2) Subjects have haecceities, a property that makes an object a different object from other objects even if they are qualitatively identical with it. I provide two arguments for the claim that we are essentially subjects. The first is the Essentiality Argument. I first define an egoistic concern as one such that necessarily, my concern about X can be egoistic if and only if I exist and persist as X. Furthermore, I argue that necessarily, I can be egoistically concerned with an entity E if and only if E is numerically identical with my subject of experience. I then conclude that we are essentially subjects of experience. My second argument, which I call the Argument of Persistence, is that we have the intuition that we persist only when there is the gradual replacement of the brain. I argue that the best candidate to explain this intuition is that we persist as subjects of experience. I further offer a conceivability argument for the claim that haecceity of the subject determines its persistence. I defend a mentally-oriented proposal regarding our nature by examining the essential properties of our existence. It solves most of the problems with the materialistic personal ontology and shows the theoretical advantages of a long-neglected approach. (shrink)
