Interaction-free measurements introduced by Elitzur and Vaidman [Found. Phys. 23, 987 (1993)] allow finding infinitely fragile objects without destroying them. Many experiments have been successfully performed showing that indeed, the original scheme and its modifications lead to reduction of the disturbance of the observed systems. However, there is a controversy about the validity of the term “interaction-free” for these experiments. Broad variety of such experiments are reviewed and the meaning of the interaction-free measurements is (...) clarified. (shrink)

A Gedanken experiment is presented where an excited and a ground-state atom are positioned such that, within the former’s half-life time, they exchange a photon with 50% probability. A measurement of their energy state will therefore indicate in 50% of the cases that no photon was exchanged. Yet other measurements would reveal that, by the mere possibility of exchange, the two atoms have become entangled. Consequently, the “no exchange” result, apparently precluding entanglement, is non-locally established between the atoms by this (...) very entanglement. This quantum-mechanical version of the ancient Liar Paradox can be realized with already existing transmission schemes, with the addition of Bell’s theorem applied to the no-exchange cases. Under appropriate probabilities, the initially-excited atom, still excited, can be entangled with additional atoms time and again, or alternatively, exert multipartite nonlocal correlations in an interaction free manner. When densely repeated several times, this result also gives rise to the Quantum Zeno effect, again exerted between distant atoms without photon exchange. We discuss these experiments as variants of interaction-free-measurement, now generalized for both spatial and temporal uncertainties. We next employ weak measurements for elucidating the paradox. Interpretational issues are discussed in the conclusion, and a resolution is offered within the Two-State Vector Formalism and its new Heisenberg framework. (shrink)

Recently highly-efficient quantum engines were devised by exploiting the stochastic energy changes induced by quantum measurement. Here we show that such an engine can be based on an interaction-free measurement, in which the meter seemingly does not interact with the measured object. We use a modified version of the Elitzur–Vaidman bomb tester, an interferometric setup able to detect the presence of a bomb triggered by a single photon without exploding it. In our case, a quantum bomb subject to (...) a gravitational force is initially in a superposition of being inside and outside one of the interferometer arms. We show that the bomb can be lifted without blowing up. This occurs when a photon traversing the interferometer is detected at a port that is always dark when the bomb is located outside the arm. The required potential energy is provided by the photon even though it was not absorbed by the bomb. A natural interpretation is that the photon traveled through the arm which does not contain the bomb—otherwise the bomb would have exploded—but it implies the surprising conclusion that the energy exchange occurred at a distance despite a local interaction Hamiltonian. We use the weak value formalism to support this interpretation and find evidence of contextuality. Regardless of interpretation, this interaction-free quantum measurement engine is able to lift the most sensitive bomb without setting it off. (shrink)

We propose a realistic device for detecting objects almost without transferring a single quantum of energy to them. The device can work with an efficiency close to 100% and relies on two detectors counting both presence and absence of the objects. Its possible usage in performing fundamental experiments as well as possible applications are discussed.

A novel manifestation of nonlocality of quantum mechanics is presented. It is shown that it is possible to ascertain the existence of an object in a given region of space without interacting with it. The method might have practical applications for delicate quantum experiments.

We propose a Quantum Field Theory description of beams on a Mach–Zehnder interferometer and apply the method to describe Interaction Free Measurements, concluding that there is a change of momentum of the fields in IFMs. Analysing the factors involved in the probability of emission of low-energy photons, we argue that they do not yield meaningful contributions to the probabilities of the IFMs.

In this paper, I propose a framework that supports both free will and anomalous mind-matter interaction (psychokinesis). I begin by considering the argument by the physicist Sean Carroll that the laws of physics as we understand them rule out psychokinesis (and other modes of psi). I find Carroll’s claims problematic, in part due to what I believe are misunderstandings of arguments borrowed from David Hume. I proceed to consider a more dispositional notion of causality (in contrast to one (...) characterized by universal and necessary laws) which I argue is more hospitable to both psychokinesis and free will. I then incorporate recent work from the philosophy of mind and science to arrive at a framework that supports both real volition and psychokinesis, which I argue are intimately linked. This approach is fundamentally dispositional, but grounded in an ontologically prior field of awareness and potentiality. I also consider that the regularities (or causal natures) we observe in our physical world are ultimately supported by what we might term teleological “intentions” within a nonlocal, mind-like quantum ground.

We present an analysis of the Frauchiger–Renner Gedankenexperiment from the point of view of the relational interpretation of quantum mechanics. Our analysis shows that the paradox obtained by Frauchiger and Renner disappears if one rejects promoting one agent’s certainty to another agent’s certainty when it cannot be validated by records from the past. A by-product of our analysis is an interaction-free detection scheme for the existence of such records.

Many jurisdictions have put regulatory strategies in place to provide incentives and safeguards to whistleblowers to encourage whistleblowing on corporate wrongdoings. One such strategy is the provision of a financial incentive to the whistleblower if the complaint leads to a successful regulatory enforcement action against the offending organization. We conducted an experiment using professional accountants as participants to examine whether such an incentive encourages potential whistleblowers to report an observed financial reporting fraud to a relevant external authority. We also examine (...) the effect of perceived seriousness of the wrongdoing on accountants’ intention to whistleblow. We find that a financial incentive results in a higher intention to whistleblow to a relevant external authority. We also find that perceptions of the seriousness of the wrongdoing are significantly and positively associated with accountants’ intention to whistleblow to a relevant external authority. We find a significant interaction between the provision of a financial incentive and the perceived seriousness of the wrongdoing on the intention to report the wrongdoing externally. The intention to report the financial reporting fraud externally is higher when the level of perceived seriousness is higher, regardless of the availability of a financial incentive. However, when the perceived level of seriousness is lower, the presence of financial incentive results in a higher intention to report the financial reporting fraud externally. These findings indicate that the impact of a financial incentive on the intention to whistleblow is moderated by perceptions of the seriousness of the wrongdoing. (shrink)

In this paper we examine Interaction-free measurement where both the probe and the object are quantum particles. We argue that in this case the description of the measurement procedure must by symmetrical with respect to interchange of the roles of probe and object. A thought experiment is being suggested that helps to determine what does and what doesn’t happen to the state of the particles in such a setup. It seems that unlike the case of classical object, here (...) the state of both the probe and the object must change. A possible explanation of this might be that the probe and the object form an entangled pair as a result of non-interaction. (shrink)

The polemical term “interaction-free measurement” (IFM) is analyzed in its interpretative nature. Two seminal works proposing the term are revisited and their underlying interpretations are assessed. The role played by nonlocal quantum correlations (entanglement) is formally discussed and some controversial conceptions in the original treatments are identified. As a result the term IFM is shown to be consistent neither with the standard interpretation of quantum mechanics nor with the lessons provided by the EPR debate.

The fungal cell wall is a dynamic structure that protects the cell from changes in osmotic pressure and other environmental stresses, while allowing the fungal cell to interact with its environment. The structure and biosynthesis of a fungal cell wall is unique to the fungi, and is therefore an excellent target for the development of anti‐fungal drugs. The structure of the fungal cell wall and the drugs that target its biosynthesis are reviewed. Based on studies in a number of fungi, (...) the cell wall has been shown to be primarily composed of chitin, glucans, mannans and glycoproteins. The biosynthesis of the various components of the fungal cell wall and the importance of the components in the formation of a functional cell wall, as revealed through mutational analyses, are discussed. There is strong evidence that the chitin, glucans and glycoproteins are covalently cross‐linked together and that the cross‐linking is a dynamic process that occurs extracellularly.

In this essay, after first briefly reviewing the literature on experimental philosophy and how and why it is important especially for contemporary analytic philosophy, we focus on two earliest experimental research papers on free will intuitions. We also present psychological mechanisms that try to explain why both philosophers and ordinary people have incompatibilist and compatibilist intuitions and free will and moral responsibility. We then move on to another experimental research on moral intuitions and develop a dual process model (...) based on the model to explain moral intuitions. However, our dual interacting-process model is not intended for moral intuitions but free will intuitions. Finally, we critically examine other mechanism and briefly defend our model. (shrink)

Research on human-animal interaction has skyrocketed in the last decade. Rapid urbanization has led scientists to investigate its impact on several species living in the vicinity of humans. Domesticated dogs (Canis lupus familiaris) are one such species that interact with humans and are also called man’s best friend. However, when it comes to the free-ranging population of dogs, interactions become quite complicated. Unfortunately, studies regarding free-ranging dog-human interactions are limited even though the majority of the world’s dog (...) population is free-ranging. In this study, we observed twelve groups of free-ranging dogs in their natural habitat, the streets. We divided the study areas into two zones, namely – intermediate and high flux, based on human activity or movement. Six groups from each of the zones were observed mostly during daytime. We used social network analysis (SNA) to explore the dog-dog (intraspecific) and dog-human (interspecific) interactions. It was surprising to observe higher instances of interspecific interactions than the intraspecific ones, irrespective of the zones. Humans, in significantly higher occasions, initiated both positive and negative interactions in comparison to dogs. Our findings conclude that humans are a crucial part of the interaction network of Indian free-ranging dogs. (shrink)

Zeilinger's observation that phenomena of the Aharonov-Bohm type lead to non-dispersive, i.e., energy-independent, phase shifts in interferometers is generalized in a new proof which shows that the precise condition for nondispersivity is a force-free interaction. The converse theorem is disproved by a conceptual counter-example. Applications to several nondispersive interference phenomena are reviewed briefly. Those fall into two classes which are objectively distinct from each other in that in the first class phase shifts depend only on the topology of (...) the interfering beam paths, while in the second class force-free physical interactions take place at identifiable points along the path. Apparent disagreements in the literature about the topological nature of the phenomena in the second class stem from differing definitions. (shrink)

Empirical evidence from the COVID-19 pandemic shows that women carried the major burden of additional housework in families. In a mixed-methods study, we investigate female and male remote workers’ experiences of working from home during the pandemic. We used the free association technique to uncover remote workers’ representations about WFH. Based on a sample of 283 Austrian remote workers cohabitating with their intimate partners our findings revealed that in line with traditional social roles, men and women in parent roles (...) are likely to experience WFH differently: Mothers’ representations about WFH emphasize perceived incompatibility between the work and non-work sphere whereas fathers’ representations highlight work-family facilitation of WFH. However, gender differences were also prevalent for women and men without children: Women seem to particularly benefit from more concentration at home, whereas men consider WFH as more efficient, practical and leading to less work. Thus, our findings imply that gender affected perceptions of WFH during the pandemic independently from children, but children seemed to increase the existing burden, in particular for women. To conclude, WFH can generally be seen as an enabler to reduce work-life/family conflict for both women and men, but bears different challenges based on the contextual situation. (shrink)

Quantitative genetics (QG) analyses variation in traits of humans, other animals, or plants in ways that take account of the genealogical relatedness of the individuals whose traits are observed. “Classical” QG, where the analysis of variation does not involve data on measurable genetic or environmental entities or factors, is reformulated in this article using models that are free of hypothetical, idealized versions of such factors, while still allowing for defined degrees of relatedness among kinds of individuals or “varieties.” The (...) gene - free formulation encompasses situations encountered in human QG as well as in agricultural QG. This formulation is used to describe three standard assumptions involved in classical QG and provide plausible alternatives. Several concerns about the partitioning of trait variation into components and its interpretation, most of which have a long history of debate, are discussed in light of the gene-free formulation and alternative assumptions. That discussion is at a theoretical level, not dependent on empirical data in any particular situation. Additional lines of work to put the gene-free formulation and alternative assumptions into practice and to assess their empirical consequences are noted, but lie beyond the scope of this article. The three standard QG assumptions examined are: (1) partitioning of trait variation into components requires models of hypothetical, idealized genes with simple Mendelian inheritance and direct contributions to the trait; (2) all other things being equal, similarity in traits for relatives is proportional to the fraction shared by the relatives of all the genes that vary in the population (e.g., fraternal or dizygotic twins share half of the variable genes that identical or monozygotic twins share); (3) in analyses of human data, genotype-environment interaction variance (in the classical QG sense) can be discounted. The concerns about the partitioning of trait variation discussed include: the distinction between traits and underlying measurable factors; the possible heterogeneity in factors underlying the development of a trait; the kinds of data needed to estimate key empirical parameters; and interpretations based on contributions of hypothetical genes; as well as, in human studies, the labeling of residual variance as a non-shared environmental effect; and the importance of estimating interaction variance.

When the history of life on earth is viewed as a history of cell division, all of life becomes a single cell lineage. The growth and differentiation of this lineage in reciprocal interaction with its environment can be viewed as a developmental process; hence the evolution of life on earth can also be seen as the development of life on earth. Here, in reviewing this field, some potentially fruitful research directions suggested by this change in perspective are highlighted. Variation (...) and selection become, for example, bidirectional information flows between scales, while the notions of “cooperation” and “competition” become scale relative. The language of communication, inference, and information processing becomes more useful than the language of causation to describe the interactions of both homogeneous and heterogeneous living systems at any scale. Emerging scale‐free theoretical frameworks such as predictive coding and active inference provide conceptual tools for reconceptualizing biology as the study of a unified, multiscale dynamical system.

Scale-free network models describe many natural and social phenomena. In particular, networks of interacting components of a living cell were shown to possess scale-free properties. A recent study(1) compares the system-level properties of metabolic and information networks in 43 archaeal, bacterial and eukaryal species and claims that the scale-free organization of these networks is more conserved during evolution than their content.

Our freedoms in cyberspace are those granted by code and the protocols it implements. When man and machine interact, co-exist, and intermingle, cyberspace comes to interpenetrate the real world fully. In this cyborg world, software retains its regulatory role, becoming a language of interaction with our extended cyborg selves. The mediation of our extended selves by closed software threatens individual autonomy. We define a notion of freedom for software that does justice to our conception of it as language, sketching (...) the outlines of a social and political philosophy for a cyborg world. In a cyberspace underwritten by free software, political structures become contingent and flexible: the polity can choose to change the extent and character of its participation. The rejection of opaque power is an old anarchist ideal: free software, by making power transparent, carries the potential to place substantive restrictions on the regulatory power of cyborg government.

Interactions of fathers and their children with autism1 The aim of the present study was to compare the activity of fathers and their children with autism with those of children with Down syndrome, and normally developing children during the father-child interaction. Participants were 14 children with autism and their fathers, 15 children with Down syndrome and their fathers, and 16 normally developing children and their fathers. The age of subjects was between 3.0 and 6.0 years old. The study consisted (...) of one 15-minute free-play session in the father-child diad, taking place in the experiment room. Differences between the groups of fathers were found in terms of three variables under analysis: frequency of looking at the child, physical contact with the child and suggesting play. Children with autism brought objects to their fathers or pointed out objects and directed their fathers' attention by vocalising less frequently than children with Down syndrome and normally developing children. Moreover, children with autism exhibited the fewest vocalisations combined with looking at the father and exhibited many more behaviours involving running and moving about the room than normally developing children. Self-stimulating behaviours were the most frequent in children with autism, with no differences in that respect found between children with Down syndrome and normally developing children. The analysis of fathers' behaviour demonstrates that fathers of children with developmental disorders focus on observing their children and attempt to keep close contact with them to a larger extent than fathers of normally developing children. The pattern of differences in the activity of fathers of children with autism and children with Down syndrome does not paint a clear picture. In general, fathers from both groups actively sought to maintain contact with their children. Differences in the activity during play between children with autism and the other subjects in the study are consistent with the clinical features of autism. (shrink)

Free will has been the object of debate in the context of addiction given that addiction could compromise an individual’s ability to choose freely between alternative courses of action. Proponents of the brain-disease model of addiction have argued that a neuroscience perspective on addiction reduces the attribution of free will because it relocates the cause of the disorder to the brain rather than to the person, thereby diminishing the blame attributed to the person with an addiction. Others have (...) worried that such displacement of free will attribution would make the person with a drug addiction less responsible. Using the paradigmatic literature on the seductive allure of neuroscience explanations, we tested whether neuroscience information diminishes attributions of free will in the context of addiction and whether respondent characteristics influence these attributions and modulate the effect of neuroscience information. We performed a large-scale, web-based experiment with 2,378 German participants to explore how attributions of free will in the context of addiction to either alcohol or cocaine are affected by: (1) a text with a neurobiological explanation of addiction, (2) a neuroimage showing effects of addiction on the brain, and (3) a combination of a text and a neuroimage, in comparison to a control group that received no information. Belief in free will was measured using the FAD-Plus scale and was, subsequent to factor analysis, separated into two factors: responsibility and volition. The investigated respondent characteristics included gender, age, education, self-reported knowledge of neuroscience, substance-use disorder (SUD), and having a friend with SUD. We found that attributions of volition (in the cocaine-subsample) were reduced in the text and neuroimage-treatment compared to the control group. However, respondent characteristics such as education and self-reported knowledge of neuroscience were associated with lower attributions of responsibility for both substances, and education was associated with lower attribution of volition for the alcohol sub-sample. Interaction analyses showed that knowledge of neuroscience was found to generally decrease attribution of responsibility. Further research on attribution of free will should consider the effects of context and respondent characteristics, which appeared surprisingly larger than those induced by experimental treatments.

Free Public Reason examines the idea of public justification, stressing its importance but also questioning the coherence of the concept itself. Although public justification is employed in the work of theorists such as John Rawls, Jeremy Waldron, Thomas Nagel, and others, it has received little attention on its own as a philosophical concept. In this book Fred D'Agostino shows that the concept is composed of various values, interests, and notions of the good, and that no ranking of these is (...) possible. The notion of public justification itself is thus shown to be contestable. In demonstrating this, D'Agostino undermines many current political theories that rely on this concept. Having broken down the foundations of public justification, D'Agostino then offers an alternative model of how a workable consensus on its meaning might be reached through the interactions of a community of interpreters or delegates at a constitutional convention.

This paper responds to continuing commentary on Velmans (2002a) “How could conscious experiences affect brains,” a target article for a special issue of JCS. I focus on the final question dealt with by the target article: how free will relates to preconscious and conscious mental processing, and I develop the case for preconscious free will. Although “preconscious free will” might appear to be a contradiction in terms, it is consistent with the scientific evidence and provides a parsimonious (...) way to reconcile the commonsense view that voluntary acts are freely chosen with the evidence that conscious wishes and decisions are determined by preconscious processing in the mind/brain. I consider alternative interpretations of how “conscious free will” might operate by Libet and by Mangan and respond to doubts about the extent to which the operations of mind are revealed in consciousness, raised by Claxton and Bouratinos. In reconciling commonsense attributions of freedom and responsibility with the findings of science, preconscious free will can be shown to have practical consequences for adjudications in law.

During the past decade, M.W. Evans and his coworkers have been developing so-called “Evans” or “ECE theory” that intends to serve as an unified field theory. One of its predictions is an existence of a radiation magnetic field called a “B(3)-field” which should accompany a circularly polarized electromagnetic radiation. This field should affect free electrons in two ways: (1) the electrons should behave in the B(3)-field in the same way as in a classical magnetic field (i.e., Larmor precession) and (...) moreover, (2) the electrons should undergo quantum interaction with the B(3)-field with the formation of a spin connection resonance. This paper presents an experimental test of the B(3)-field existence by observing the changes in trajectories of free electrons in special detector, when strong (up to 200 W/m2) continuous circularly polarized microwave radiation of a frequency of 2.45 GHz is applied. We have not detected any sign of B(3)-field in presented experiment. It follows that if the B(3)-field really exists, it should be at least 4 orders of magnitude smaller than the Evans’ theory predicts. (shrink)

The topic of human free will has received more attention in the past several years due to the important discoveries of neuroscience but no consensus of opinion is evident in related disciplines. The traditional approach to understanding free will in philosophy employs conceptual analysis to determine whether humans have freedom of choice. Theology affirms that every person has free choice although God is somehow behind all human decisions. Evolutionary psychology points to human behavior as the product of (...) biological processes and antecedent events. And neuroethics attempts to define what it means to be a thinking moral agent by investigating how neurons in the brain and chemical interactions combine to produce conscious actions. An assessment and evaluation of these various positions is given in light of the evidence. The issue of whether a person can be held morally responsible for their actions hinges on whether those actions originate from free will or are the result of determinism. Theology makes assumptions of the existence of an absolute deity that has a hand in human decision making, but there is no agreement regarding the nature of that intervention. Recent scientific discoveries confront traditionally held religious beliefs and necessitate the creation of a new theology and articles of faith. (shrink)

My target article (henceforth referred to as TA) presents evidence for causal interactions between consciousness and brain and some standard ways of accounting for this evidence in clinical practice and neuropsychological theory. I also point out some of the problems of understanding such causal interactions that are not addressed by standard explanations. Most of the residual problems have to do with how to cross the “explanatory gap” from consciousness to brain. I then list some of the reasons why the route (...) across this gap suggested by physicalism won't work, in spite of its current popularity in consciousness studies. My own suggested route across the explanatory gap is more subterranean, where consciousness and brain can be seen to be dual aspects of a unifying, psychophysical mind. Some of the steps on this deeper route still have to be filled in by empirical research. But (as far as I can judge) there are no gaps that cannot be filled—just a different way of understanding consciousness, mind, brain and their causal interaction, with some interesting consequences for our understanding of free will. The commentaries on TA examined many aspects of my thesis viewed from both Western and Eastern perspectives. This reply focuses on how dual-aspect monism compares with currently popular alternatives such as “nonreductive physicalism”, clarifies my own approach, and reconsiders how well this addresses the “hard” problems of consciousness. We re-examine how conscious experiences relate to their physical/functional correlates and whether useful analogies can be drawn with other, physical relationships that appear to have dual-aspects. We also examine some fundamental differences between Western and Eastern thought about whether the existence of the physical world or the existence of consciousness can be taken for granted (with consequential differences about which of these is “hard” to understand). I then suggest a form of dual-aspect Reflexive Monism that might provide a path between these ancient intellectual traditions that is consistent with science and with common sense. (shrink)

The paper presents two empirical cases of expert musicians—a classical string quartet and a solo, free improvisation saxophonist—to analyze the explanatory power and reach of theories in the field of expertise studies and joint action. We argue that neither the positions stressing top-down capacities of prediction, planning or perspective-taking, nor those emphasizing bottom-up embodied processes of entrainment, motor-responses and emotional sharing can do justice to the empirical material. We then turn to hybrid theories in the expertise debate and interactionist (...) accounts of cognition. Attempting to strengthen and extend them, we offer ‘Arch’: an overarching conception of musical interaction as an externalized, cognitive scaffold that encompasses high and low-level cognition, internal and external processes, as well as the shared normative space including the musical materials in which the musicians perform. In other words, ‘Arch’ proposes interaction as a multivariate multimodal overarching scaffold necessary to explain not only cases of joint performance, but equally of solo improvisation. (shrink)

Do humans have a free choice of which actions to perform? Three recent developments of modern science can help us to answer this question. First, new investigative tools have enabled us to study the processes in our brains which accompanying our decisions. The pioneer work of Benjamin Libet has led many neuroscientists to hold the view that our conscious intentions do not cause our bodily movements but merely accompany them. Then, Quantum Theory suggests that not all physical events are (...) fully determined by their causes, and so opens the possibility that not all brain events may be fully determined by their causes, and so maybe - if neuroscience does not rule this out - there is a role for intentions after all. Finally, a theorem of mathematics, Godel's theory, has been interpreted to suggest that the initial conditions and laws of development of a mathematician's brain could not fully determine which mathematical conjectures he sees to be true. Papers by Patrick Haggard, Tim Bayne, Harald Atmanspacher and Stefan Rotter, Solomon Feferman, and John Lucas investigate these issues. The extent to which human behaviour is determined by brain events may well depend on whether conscious events, such as intentions, are themselves merely brain events, or whether they are separate events which interact with brain events (perhaps in the radical form that intentions are events in our soul, and not in our body). The papers of Frank Jackson, Richard Swinburne, and Howard Robinson investigate these issues. The remaining papers, of Galen Strawson, Helen Steward, and R.A. Duff, consider what kind of free will we need in order to be morally responsible for our actions or to be held guilty in a court of law. Is it sufficient merely that our actions are uncaused by brain events, or what? (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Free Will and the Rebel Angels in Medieval Philosophy by Tobias HoffmannNicholas OgleFree Will and the Rebel Angels in Medieval Philosophy by Tobias Hoffmann (Cambridge: Cambridge University Press, 2021), xiv + 292 pp.Modern readers are often perplexed by the frequency and rigor with which angels are discussed in medieval philosophical texts. To the untrained eye, it may seem as if debates concerning the various properties and abilities (...) of purely spiritual beings are the epitome of Scholastic extravagance, which can be safely disregarded—if not outright ridiculed—as a fanciful diversion from more essential philosophical concerns. The truth, of course, is that angelological reflection gave rise to some of the most original philosophical ideas of the Middle Ages, from Anselm's two affectiones of the will to Aquinas's "real distinction" between essence and existence. Far from being an idiosyncratic theological addendum to an already complete philosophical system, consideration of the angelic nature was in fact a central component of medieval philosophy, without which certain crucial metaphysical and psychological insights might not have occurred. This often-neglected truth is given detailed expression in Tobias Hoffmann's Free Will and the Rebel Angels in Medieval Philosophy, which explores how philosophical investigation into the fall of the angels—that is, the hypothesis of an evil choice made by rational beings under optimal psychological conditions—helped bring about significant advances in medieval debates about free will. Focusing on the century immediately following the reception of Aristotle's action theory in the Latin West (from roughly the 1220s to the 1320s), Hoffmann examines how theological claims regarding angelic sin influenced medieval thinkers as they sought to reconcile the intellectualism of Aristotelian moral psychology with their understanding of free will as the power to choose between alternatives.This period is particularly deserving of study, Hoffmann argues, because it was then that the existence of free will first began to be "investigated within a philosophical account of action," rather than merely asserted on theological grounds as a necessary corollary of the doctrines of grace and sin (1). Consequently, theological anthropology took what Hoffmann calls a "psychological turn," with theologians newly determined to explain rational agency in terms of the interaction between different powers of the soul. In Hoffmann's estimation, the subsequent debates over the respective roles of intellect and will in the process of decision-making, as well as the relation between faulty cognition and voluntary wrongdoing, gave rise to some of the most innovative theories of free will in the later Middle Ages—including not only those of celebrated thinkers such as Thomas Aquinas and John Duns Scotus, but also those of lesser-known luminaries such as [End Page 388] John of Pouilly and Peter Auriol. Although the concerns that motivated these debates were primarily anthropological, having to do with specifically human psychological processes, Hoffmann's study foregrounds the role that the angels played in the unfolding of various controversies. Comparing medieval angelological discussion to the thought experiments commonly employed by contemporary philosophers, Hoffmann argues that angels proved significant because they provided a subject matter in which rational freedom could be considered in a pure and ideal form, abstracted from any material constraints (3). While the angelic nature was certainly regarded as worthy of study in its own right, it was also often viewed as an opportunity to explore the nature of cognition and volition simpliciter, in relation to which the distinctiveness of human psychology could be better understood.The book is divided into three parts, each of which traces the historical development of a distinct topic related to the free will debate. In the first part, Hoffmann presents a lucid account of the various ways that medieval thinkers employed Aristotelian ideas—including not only the essentials of his action theory, but also metaphysical doctrines such as the distinction between active and passive powers—as they sought to explain the psychological origins of free will. Comprising over half the text, these chapters provide a comprehensive overview of the free will debate from its origins in the writings of Anselm of Canterbury to its culmination in the proto-modern theorizing of William of Ockham, including a thorough discussion of the controversies...

Focusing on the concepts and interactions of free will, moral responsibility, and determinism, this text represents the most up-to-date account of the four major positions in the free will debate. Four serious and well-known philosophers explore the opposing viewpoints of libertarianism, compatibilism, hard incompatibilism, and revisionism The first half of the book contains each philosopher’s explanation of his particular view; the second half allows them to directly respond to each other’s arguments, in a lively and engaging conversation Offers (...) the reader a one of a kind, interactive discussion Forms part of the acclaimed Great Debates in Philosophy series.

Responses to the COVID-19 pandemic prompted people and institutions to turn to online virtual environments for a wide variety of social gatherings. In this perspectives article, we draw upon our previous work and interviews with Ghanaian Christian leaders to consider implications of this shift. Specifically, we propose that the shift from physical to virtual interactions mimics and amplifies the neoliberal individualist experience of abstraction from place associated with Eurocentric modernity. On the positive side, the shift from physical to virtual environments (...) liberates people to selectively pursue the most fulfilling interactions, free from constraints of physical distance. On the negative side, the move from physical to virtual space necessitates a shift from material care and tangible engagement with the local community to the psychologization of care and pursuit of emotional intimacy in relations of one’s choosing—a dynamic that further marginalizes people who are already on the margins. The disruptions of the pandemic provide an opportunity to re-set social relations, to design ways of being that better promote sustainable collective well-being rather than fleeting personal fulfillment.

This paper discusses free-choice like effects in generics. Just as Jane may drink coffee or tea can be used to convey Jane may drink coffee and Jane may drink tea (she is free to choose ), some generics with disjunctive predicates can be used to convey conjunctions of simpler generics: elephants live in Africa or Asia can be used to convey elephants live in Africa and elephants live in Asia. Investigating these logically slightly more complex generics and especially (...) the free-choice like effects throws light on both the semantics of generics and the interaction between world knowledge and the interpretive options generics offer. This paper presents a package of semantic and pragmatic hypotheses to account for the data, including why the effect is absent in the superficially logically similar elephants live in Africa or give birth to live young.

It’s been agreed for decades that not only does Determinism pose a big problem for our choosing from available alternatives, but its denial seems to pose a bit of a problem, too. It’s argued here that only Determinism, and not its denial, means no real choice for us.But, what explains the appeal of the thought that, where things aren’t fully determined, to that extent they’re just a matter of chance? It's the dominance of metaphysical suppositions that, together, comprise Scientiphicalism: Wholly (...) composed of such mindless physical parts as electrons, you are a being whose powers are all physical powers, physically deriving from the powers of your parts and their physical arrangements. Scientiphicalisrn conflicts with your having real choice.Some fairly conservative alternatives to Scientiphicalism may allow for choice. Two are briefly discussed: On the further-fetched, you are a Cartesian mental being, a nonphysical being in powerful interaction with physical things. On the more conservative approach, you are wholly composed of physical parts, but some of your powers are radically emergent, including your power to choose.Finally, it’s argued that, if you choose, you must be, to some extent, exempt from natural laws.

This volume, edited by René Brouwer and Emmanuele Vimercati, deals with the debate about fate, providence and free will in the early Imperial age. This debate is rekindled in the 1st century CE during emperor Augustus' rule and ends in the 3rd century CE with Plotinus and Origen, when the different positions in the debate were more or less fully developed. The book aims to show how in this period the notions of fate, providence and freedom were developed and (...) debated, not only within and between the main philosophical schools, that is Stoicism, Aristotelianism, and Platonism, but also in the interaction with other, "religious" movements, here understood in the general sense of groups of people sharing beliefs in and worship of (a) superhuman controlling power(s), such as Gnosticism, Hermetism as well as Judaism and Christianity.

Interaction between adults and infants by nature constitutes a strong powerasymmetry relationship. Based on the assumption that communicative practices with infants are inseparably intertwined with broader cultural ideologies of good child care, this paper will contrast how parents in two distinct socio-cultural communities deal with power asymmetry in interactions with 3-months old infants. The study consists of a microanalysis of videotaped free play mother-infant interactions from 20 middle class families in Muenster, Germany and 20 traditional farming Nso families (...) in Kikaikelaki, Cameroon. Analysis followed a discursive psychology approach. The focus of analysis is on how mothers handle and negotiate power-distance in these interactions and what discursive strategies they draw on. Mothers in both groups used various forms of directives and control strategies. The Muenster mothers, however, mainly used mitigated directives that can be seen as strategies to reduce the competence gap between mother and child, while the Nso mothers mainly used upgraded directives to stress the hierarchical discrepancy between mother and child. The different strategies are discussed in light of the prevailing broader cultural ideologies and the normative orientations that they reflect. Finally, the findings are discussed with regard to possible developmental consequences of these distinct cultural practices for the child. Keywords: power-asymmetry; mother-infant interaction; discursive psychology; culture; Nso farmers; Muenster middle class families. (shrink)

In this paper, we set out to develop a theoretical and conceptual framework for the new field of Radical Embodied Cognitive Neuroscience. This framework should be able to integrate insights from several relevant disciplines: theory on embodied cognition, ecological psychology, phenomenology, dynamical systems theory, and neurodynamics. We suggest that the main task of Radical Embodied Cognitive Neuroscience is to investigate the phenomenon of skilled intentionality from the perspective of the self-organization of the brain-body-environment system, while doing justice to the phenomenology (...) of skilled action. In previous work, we have characterized skilled intentionality as the organism's tendency toward an optimal grip on multiple relevant affordances simultaneously. Affordances are possibilities for action provided by the environment. In the first part of this paper, we introduce the notion of skilled intentionality and the phenomenon of responsiveness to a field of relevant affordances. Second, we use Friston's work on neurodynamics, but embed a very minimal version of his Free Energy Principle in the ecological niche of the animal. Thus amended, this principle is helpful for understanding the embeddedness of neurodynamics within the dynamics of the system “brain-body-landscape of affordances.” Next, we show how we can use this adjusted principle to understand the neurodynamics of selective openness to the environment: interacting action-readiness patterns at multiple timescales contribute to the organism's selective openness to relevant affordances. In the final part of the paper, we emphasize the important role of metastable dynamics in both the brain and the brain-body-environment system for adequate affordance-responsiveness. We exemplify our integrative approach by presenting research on the impact of Deep Brain Stimulation on affordance responsiveness of OCD patients. (shrink)
