Within the causal modeling literature, debates about the Causal Faithfulness Condition have concerned whether it is probable that the parameters in causal models will have values such that distinct causal paths will cancel. As the parameters in a model are fixed by the probability distribution over its variables, it is initially puzzling what it means to assign probabilities to these parameters. I propose that to assign a probability to a parameter in a model is to treat that parameter as a (...) function of a variable in an augmented model. By combining this proposal with widely adopted principles regarding which variables must be included in a model, I argue that the various proposed counterexamples to CFC involving coordinated parameters are not genuine counterexamples. I then consider the cases in which CFC fails due not to coordination, but by coincidence, and propose explanatory and predictive bases for ruling out such coincidences without presuming that they are improbable. The aim of the proposed defenses is not to show that CFC never fails, but rather to argue that its use in a particular context may be defended using general modeling assumptions rather than by relying on claims about how often it fails.

A common strategy for simplifying complex systems involves partitioning them into subsystems whose behaviors are roughly independent of one another at shorter timescales. Dynamic causal models clarify how doing so reveals a system’s nonequilibrium causal relationships. Here I use these models to elucidate the idealizations and abstractions involved in representing a system at a timescale. The models reveal that key features of causal representations—such as which variables are exogenous—may vary with the timescale at which a system is considered. This has (...) implications for debates regarding which systems can be represented causally. (shrink)

Markus (2021) argues that the causal modelling frameworks of Pearl and Rubin are not ‘strongly equivalent’, in the sense of saying ‘the same thing in different ways’. Here I rebut Markus’ arguments against strong equivalence. The differences between the frameworks are best illuminated not by appeal to their causal semantics, but rather reflect pragmatic modelling choices.

A cause may influence its effect via multiple paths. Paradigmatically (Hesslow [1974]), taking birth control pills both decreases one’s risk of thrombosis by preventing pregnancy and increases it by producing a blood chemical. Building on Pearl ([2001]), I explicate the notion of a path-specific effect. Roughly, a path-specific effect of C on E via path P is the degree to which a change in C would change E were they to be transmitted only via P. Facts about such effects may (...) be gleaned from the structural equations commonly used to represent the causal relationships among variables. I contrast my analysis of the Hesslow case with those given by theorists of probabilistic causality, who mistakenly link it to issues of causal heterogeneity, token-causation and indeterminism. The reason probabilistic theories misdiagnose this case is that they pay inadequate attention to the structural relationships among variables. (shrink)

Discussions of the causal status of race focus on the question of whether race itself can be experimentally manipulated. Yet many experiments testing for racial discrimination do not manipulate race, but rather a signal by which race influences an outcome. Such signal manipulations are easily formalized, though contexts of discrimination introduce significant philosophical complications. Whether a signal counts as a signal for race is not merely a causal question, but depends on sociological and normative issues regarding discrimination. The notion of (...) signal manipulation enables one to take these issues into account while still using causal counterfactual tests to detect discrimination. The analysis provided here is compatible with social constructivism and helps differentiate between cases in which it is more or less fruitful to model race causally. (shrink)

Dynamical models of cognition have played a central role in recent cognitive science. In this paper, we consider a common strategy by which dynamical models describe their target systems neither as purely static nor as purely dynamic, but rather using a hybrid approach. This hybridity reveals how dynamical models involve representational choices that are important for understanding the relationship between dynamical and non-dynamical representations of a system.

In a recent paper, Brandon and Nijhout argue against genic selectionism—the thesis, roughly, that evolutionary processes are best understood from the gene’s-eye point of view—by presenting a case in which genic models of selection allegedly make predictions that conflict with the (correct) predictions of higher-level genotypic selection models. Their argument, if successful, would refute the widely held belief that genic models and higher-level models are predictively equivalent. Here, I argue that Brandon and Nijhout fail to demonstrate that the models make (...) incompatible predictions. (shrink)

This book explores the philosophy of love through the thought and life of Rabbi Akiva ben Joseph. Readers of the Talmud are introduced to Rabbi Akiva through the iconic story of his love for his wife Rachel. From this starting point, Naftali Rothenberg conducts a thorough examination of the harmonious approach to love in the obstacle-laden context of human reality. Discussing the deterioration of passion into simple lust, the ability to contend with suffering and death, and so forth, Rothenberg (...) addresses the deepest and most pressing questions about human love. The readings and observations offered here allow readers to acquire the wisdom of love-not merely as an assemblage of theoretical arguments and abstract statements, but as an analysis of the internal contradictions and difficulties revealed in the context of attempts to realize and implement harmonious love.

Some recent accounts of constitutive relevance have identified mechanism components with entities that are causal intermediaries between the input and output of a mechanism. I argue that on such accounts there is no distinctive inter-level form of mechanistic explanation and that this highlights an absence in the literature of a compelling argument that there are such explanations. Nevertheless, the entities that these accounts call ‘components’ do play an explanatory role. Studying causal intermediaries linking variables Xand Y provides knowledge of the (...) counterfactual conditions under which X will continue to bring about Y. This explanatory role does not depend on whether intermediate variables count as components. The question of whether there are distinctively mechanistic explanations remains open. (shrink)

Causal representations are distinguished from non-causal ones by their ability to predict the results of interventions. This widely-accepted view suggests the following adequacy condition for causal models: a causal model is adequate only if it does not contain variables regarding which it makes systematically false predictions about the results of interventions. Here I argue that this condition should be rejected. For a class of equilibrium systems, there will be two incompatible causal models depending on whether one intervenes upon a certain (...) variable to fix its value, or ‘lets go’ of the variable and allows it to vary. The latter model will fail to predict the result of interventions on the let-go-of variable. I argue that there is no basis for preferring one of these models to the other, and thus that models failing to predict interventions on particular variables can be just as adequate as those making no such false predictions. This undermines a key argument (Dash in Caveats for causal reasoning with equilibrium models. University of Pittsburgh. PhD thesis, 2003) against relying upon causal models inferred from equilibrium data. (shrink)

The book Chronicle of Separation is an attempt to write on Derrida, to Derrida and from Derrida on the basis of a pathetic experience, which, in various ways, describes and enacts the pathetic experience of deconstruction itself. The book tackles the weight of emotions that is at the heart of deconstructive reading, treating deconstruction's weak, fragile and parasitic mode of thinking as a deconstruction of emotion, on emotion and as emotion. Chronicle of Separation examines these themes beginning with a descriptive (...) and an analytic reading of Derrida's Memoirs: For Paul de Man and The Post Card, as embodiments of deconstruction's melancholic friendship which inscribes its disillusioned love in what it calls the 'postal condition'. The book then moves on to a feminization of Derrida, experimenting in different modes of writing. It firstly discusses Fred Zinneman's film Julia about a mournful friendship between women. Then it performs a deconstructive meditation on the anorexic person suggesting that anorexia constitutes a paradoxical embodiment of deconstruction. The concluding chapter presents a complete incorporation of Derrida into a fictional text that re-writes the biblical Book of Ruth. (shrink)

The essay examines Scholem's letter-confession on the Hebrew language addressed to Rosenzweig from two perspectives hitherto ignored in the ongoing interpretative consideration of this document: Scholem's repression of the literary space and his consequent exclusion of madness. The essay follows several threads in Derrida's own ‘internal’ reading of the letter, and leans on other Derridean writings such as The Monolingualism of the Other, Schibboleth: For Paul Celan and ‘Cogito and the History of Madness’ in order to suggest two distinct encounters (...) between Derrida and Scholem: In the first encounter, Scholem reads Derrida and proves to be deconstructing his own notions of secular and profane Hebrew, while fighting in vain for his sanity by clinging to liturgical practices against the grain of an ongoing ‘actualization’, politicization or else fictionalization of the sacred language. In the second encounter, it is Derrida who reads Scholem. By transforming the particular conditions of possibility of Hebrew into general conditions of possibility of every language contaminated by a theological-political tension, Derrida contributes some important insights for contemporary Hebrew speakers.

Cohn's (2013) theory of “Visual Narrative Grammar” argues that sequential images take on categorical roles in a narrative structure, which organizes them into hierarchic constituents analogous to the organization of syntactic categories in sentences. This theory proposes that narrative categories, like syntactic categories, can be identified through diagnostic tests that reveal tendencies for their distribution throughout a sequence. This paper describes four experiments testing these diagnostics to provide support for the validity of these narrative categories. In Experiment 1, participants (...) reconstructed unordered panels of a comic strip into an order that makes sense. Experiment 2 measured viewing times to panels in sequences where the order of panels was reversed. In Experiment 3, participants again reconstructed strips but also deleted a panel from the sequence. Finally, in Experiment 4 participants identified where a panel had been deleted from a comic strip and rated that strip's coherence. Overall, categories had consistent distributional tendencies within experiments and complementary tendencies across experiments. These results point toward an interaction between categorical roles and a global narrative structure. (shrink)

Visual narratives like comics involve a range of complex cognitive operations in order to be understood. The Parallel Interfacing Narrative‐Semantics (PINS) Model integrates an emerging literature showing that comprehension of wordless image sequences balances two representational levels of semantic and narrative structure. The neurocognitive mechanisms that guide these processes are argued to overlap with other domains, such as language and music.

`Hans Cohn has given us a personal and valuable statement about the theoretical underpinnings of his work as a psychotherapist. These can be little doubt about his contribution to our thinking practice is invaluable. Students will find Cohn's easygoing exposition of complex ideas enormously helpful' - Professor Emmy van Deurzen, Existential Analysis `One of the most important books published this year. This long-awaited book by the foremost expert on the relationship between Heidegger and psychotherapy, manages to encapsulate the (...) essence of Heidegger's thinking and make of understandable and relevant to therapists without losing any of the original meaning' - Counsellingbooks.com Anyone interested in modern philosophy is familiar with the name of Martin Heidegger but there is a serious gap in even the most complete accounts of his life and thought. This is Heidegger's association with, and influence on, psychotherapy. Hans C Cohn explores the role of Heidegger's thought in providing an alternative basis for psychotherapeutic practice to the dominant psychodynamic, humanistic and cognitive approaches, also focusing strongly on the practical therapeutic relevance of Heidegger's ideas. This book will be essential reading for students and teachers of modern philosophy, as well as existential psychotherapists, and all practitioners interested in existential approaches to therapy.

The paper outlines a model-theoretic framework for investigating and comparing a variety of mereotopological theories. In the first part we consider different ways of characterizing a mereotopology with respect to (i) the intended interpretation of the connection primitive, and (ii) the composition of the admissible domains of quantification (e.g., whether or not they include boundary elements). The second part extends this study by considering two further dimensions along which different patterns of topological connection can be classified - the strength of (...) the connection and its multiplicity.

Narratives are an integral part of human expression. In the graphic form, they range from cave paintings to Egyptian hieroglyphics, from the Bayeux Tapestry to modern day comic books (Kunzle, 1973; McCloud, 1993). Yet not much research has addressed the structure and comprehension of narrative images, for example, how do people create meaning out of sequential images? This piece helps fill the gap by presenting a theory of Narrative Grammar. We describe the basic narrative categories and their relationship to a (...) canonical narrative arc, followed by a discussion of complex structures that extend beyond the canonical schema. This demands that the canonical arc be reconsidered as a generative schema whereby any narrative category can be expanded into a node in a tree structure. Narrative “pacing” is interpreted as a reflection of various patterns of this embedding: conjunction, left-branching trees, center-embedded constituencies, and others. Following this, diagnostic methods are proposed for testing narrative categories and constituency. Finally, we outline the applicability of this theory beyond sequential images, such as to film and verbal discourse, and compare this theory with previous approaches to narrative and discourse.

This paper describes the topological aspect of a logic-based, artificial intelligence approach to formalising the qualitative description of spatial properties and relations, and reasoning about those properties and relations. This approach, known as RCC theory, has been under development for several years at the University of Leeds. The main rationale for this project is that qualitative descriptions of spatial properties and relationships, and qualitative spatial reasoning, are of fundamental importance in human thinking about the world: even where quantitative spatial data (...) are most important, they must be attached to the components of a perceived spatial structure if we are to make use of them. RCC theory covers other qualitative aspects of spatial description and reasoning, but the topological properties and relations of spatially extended entities are fundamental to our work. The topological formalisms used by mathematicians are, in general, not well suited to the task of formalising the kinds of ‘common-sense’ or ‘everyday’ qualitative spatial description and reasoning which are our primary interest. Nevertheless, we must come to grips with the concepts of topology as practised by mathematicians if we are not to risk constantly ‘reinventing wheels’. (shrink)

Cognitive Science, Volume 46, Issue 7, July 2022.

Drawn sequences of images, like those in comics and picture stories, are a pervasive and fundamental way that humans have communicated for millennia. Yet, the study of visual narratives has only recently gained traction in Cognitive Science. Here we explore what has held back the study of the cognition of visual narratives, and why researchers should join in scholarship of this ubiquitous aspect of expression.

Mechanist philosophers have examined several strategies scientists use for discovering causal mechanisms in neuroscience. Findings about the anatomical organization of the brain play a central role in several such strategies. Little attention has been paid, however, to the use of network analysis and causal modeling techniques for mechanism discovery. In particular, mechanist philosophers have not explored whether and how these strategies incorporate information about the anatomical organization of the brain. This paper clarifies these issues in the light of the distinction (...) between structural, functional and effective connectivity. Specifically, we examine two quantitative strategies currently used for causal discovery from functional neuroimaging data: dynamic causal modeling and probabilistic graphical modeling. We show that dynamic causal modeling uses findings about the brain’s anatomical organization to improve the statistical estimation of parameters in an already specified causal model of the target brain mechanism. Probabilistic graphical modeling, in contrast, makes no appeal to the brain’s anatomical organization, but lays bare the conditions under which correlational data suffice to license reliable inferences about the causal organization of a target brain mechanism. The question of whether findings about the anatomical organization of the brain can and should constrain the inference of causal networks remains open, but we show how the tools supplied by graphical modeling methods help to address it.

This article explores the way in which the practice of neuroscience, in the form of contemporary brain-imaging, has to actively define and isolate aspects of mindfulness as solely contained within the individual. Although hidden from final scientific accounts, at the centre of this process is the need for the researchers to forge brief but intimate and personal relationships with the volunteers in their studies. With their increasing interest in studying more and more complex mental processes, and in particular as researchers (...) focus on what they term `the social brain', a potential paradox arises from the commitment to the straightforward location of brain function and recognition of the more distributed and intersubjective nature of the objects of their study. Consequently, in order to elicit specific mental activities, such as empathy, the scientists inevitably employ a range of socially based resources, which includes establishing a personal relationship with the volunteers. The scientists themselves see this as ensuring that they can trust that the volunteers will participate in the ways intended. But in contrast, the article argues that the central feature is actually the creation of a sense of intimacy, which serves to align the expectations and experiences of volunteer and researcher. Yet, while this relationship is necessary in order to ensure the required mental state is generated, during the experiment itself a great deal of work is then done to ensure it can be excluded from the final conceptualization of mental activity.

This interview with Michal Ben-Naftali from March 2004 is one of Derrida's last. It begins with the question of the relationship between love, law, and justice and then moves on to discuss everything from the secret, hospitality, friendship, sacrifice, pardon and psychoanalysis to the relationship between deconstruction and melancholy.

Or, cette unité est indispensable pour penser les États-Unis d’Europe face à trois insécurités majeures : la Covid, la guerre en Ukraine et le délabrement de la planète. Il s’agit de traiter ces trois insécurités ne même temps sans sacrifier l’objectif écologique. (...) Par quels moyens?
