Relevant logics infamously have the property that they only validate a conditional when some propositional variable is shared between its antecedent and consequent. This property has been strengthened in a variety of ways over the last half-century. Two of the more famous of these strengthenings are the strong variable sharing property and the depth relevance property. In this paper I demonstrate that an appropriate class of relevant logics has a property that might naturally be characterized as the supremum of (...) these two properties. I also show how to use this fact to demonstrate that these logics seem to be constructive in previously unknown ways. (shrink)

I defend an account of explanatory depth according to which explanations in the non-fundamental sciences can be deeper than explanations in fundamental physics.

This paper argues that self-deception cannot be explained without employing a depth-psychological ("psychodynamic") notion of the unconscious, and therefore that mainstream academic psychology must make space for such approaches. The paper begins by explicating the notion of a dynamic unconscious. Then a brief account is given of the "paradoxes" of self-deception. It is shown that a depth-psychological self of parts and subceptive agency removes any such paradoxes. Next, several competing accounts of self-deception are considered: an attentional account, a (...) constructivist account, and a neo-Sartrean account. Such accounts are shown to face a general dilemma: either they are able only to explain unmotivated errors of self-perception--in which case they are inadequate for their intended purpose--or they are able to explain motivated self-deception, but do so only by being instantiation mechanisms for depth-psychological processes. The major challenge to this argument comes from the claim that self-deception has a "logic" different to other-deception--the position of Alfred Mele. In an extended discussion it is shown that any such account is explanatorily adequate only for some cases of self-deception--not by any means all. Concluding remarks leave open to further empirical work the scope and importance of depth-psychological approaches. (shrink)

This paper investigates the depth of resolution proofs, that is to say, the length of the longest path in the proof from an input clause to the conclusion. An abstract characterization of the measure is given, as well as a discussion of its relation to other measures of space complexity for resolution proofs.

Some philosophers hold that the depth of an emotion is a question of how embedded it is among the person’s other mental states. That means, the emotion is inter-connected with other states such that its alteration or removal would lead to widespread changes in the mind. This paper argues that it is necessary to distinguish two different concepts of embeddedness: the inter-connections could either be rational or causal. The difference is non-trivial. This paper argues that the rational approach cannot (...) admit that certain types of recalcitrant emotion are deep without violating requirements of charity in the interpretation of others. Furthermore, it also argues that the causal approach is necessary to explain the depth of even non-recalcitrant emotions. So, if emotional depth is to be conceived as a kind of embeddedness, the relevant concept of embeddedness must be the causal one. (shrink)

Formal symptoms of relevance usually concern the propositional variables shared between the antecedent and the consequent of provable conditionals. Among the most famous results about such symptoms are Belnap’s early results showing that for sublogics of the strong relevant logic R, provable conditionals share a signed variable between antecedent and consequent. For logics weaker than R stronger variable sharing results are available. In 1984, Ross Brady gave one well-known example of such a result. As a corollary to the main result (...) of the paper, we give a very simple proof of a related but strictly stronger result. (shrink)

Depth Calls to Depth: Jungian Psychology and Spiritual Direction in Dialogue draws on the author's dual background as a certified Jungian analyst and psychologist as well as a spiritual director with a master's degree in theology. Over the last several decades, spiritual direction has moved beyond its monastic origins to become a major force in contemporary spirituality. Its emphasis on direct spiritual experience offers a natural parallel to Jung's model of psychospiritual healing. This book describes how Jungian dreamwork (...) can enhance the practice of spiritual direction. There is much interest in Jung's thought in spiritual circles but little informed understanding of the details of his model and its application to work with individuals. In an effort to meet this need, chapters alternate between descriptions of Jung's approach, augmented by extensive case material and accounts of spiritual direction sessions. In this way, the book combines a comprehensive summary of Jung's main ideas and methodologies with vignettes that illustrate their practical application. Larger issues regarding the relationship between psychology and spirituality are discussed as well as Jung's complicated relationship with the Christian tradition. The author's background in Ignatian spirituality and the work of mystics like Meister Eckhart allow him to demonstrate how these approaches can bridge gaps between the Christian and Jungian models of spiritual growth. Parallels to 12-Step spirituality also are explored. (shrink)

Four experiments investigate the folk concept of “understanding,” in particular when and why it is deployed differently from the concept of knowledge. We argue for the positions that people have higher demands with respect to explanatory depth when it comes to attributing understanding, and that this is true, in part, because understanding attributions play a functional role in identifying experts who should be heeded with respect to the general field in question. These claims are supported by our findings that (...) people differentially withhold attributions of understanding when the object of attribution has minimal explanatory information. We also show that this tendency significantly correlates with people’s willingness to defer to others as potential experts. This work bears on a pressing issue in epistemology concerning the place and value of understanding. Our results also provide reason against positing a simple equation of knowledge and understanding. We contend that, because deference plays a crucial role in many aspects of everyday reasoning, the fact that we use understanding attributions to demarcate experts reveals a potential mechanism for achieving our epistemic aims in many domains.

This paper argues that in at least some cases, one proof of a given theorem is deeper than another by virtue of supplying a deeper explanation of the theorem — that is, a deeper account of why the theorem holds. There are cases of scientific depth that also involve a common abstract structure explaining a similarity between two otherwise unrelated phenomena, making their similarity no coincidence and purchasing depth by answering why questions that separate, dissimilar explanations of the (...) two phenomena cannot correctly answer. The connections between explanation, depth, unification, power, and coincidence in mathematics and science are compared. (shrink)

_Philosophically explores the topic of emotional depth._.

Word learning is basic to foreign language acquisition, however time consuming and not always successful. Empirical studies have shown that traditional (visual) word learning can be enhanced by gestures. The gesture benefit has been attributed to depth of encoding. Gestures can lead to depth of encoding because they trigger semantic processing and sensorimotor enrichment of the novel word. However, the neural underpinning of depth of encoding is still unclear. Here, we combined an fMRI and a behavioral study (...) to investigate word encoding online. In the scanner, participants encoded 30 novel words of an artificial language created for experimental purposes and their translation into the subjects’ native language. Participants encoded the words three times visually, audiovisually, and by additionally observing semantically related gestures performed by an actress. Hemodynamic activity during word encoding revealed the recruitment of cortical areas involved in stimulus processing. In this study, depth of encoding can be spelt out in terms of sensorimotor brain networks that grow larger the more sensory modalities are linked to the novel word. Word retention outside the scanner documented a positive effect of gestures in a free recall test in the short-term. (shrink)

The paper attempts to reconstruct some notions of Naess's semantics, and at the same time to relate them to more recent developments. On Naess's view, there is no such thing as a language in the sense of a shared structure which determines clear-cut literal meanings like Fregean Gedanken or propositions. We use words, and try to interpret each other; but there is no a priori or intuitive basis for secure and precise knowledge about language. Interpretation or understanding, as well as (...) thinking and perception, involve discrimination at higher or lower levels. There is neither a ceiling of crystal-clear propositions nor a floor of 'given' sensations or 'objective' stimuli independent of categorizations and discriminations, which might serve as a bridge for translation or interpretation between the conceptual-perceptual schemes of individuals. The notions of 'concept', 'conceptual framework', 'situation', 'situation type' and 'proposition' are defined, with some reliance on Barwise and Perry's situation semantics. Two notions of accessibility of situation types are defined; one as constructibility of the type at a given level of discrimination, i.e. in terms of objects discerned and concepts discriminated; the other as intelligibility of the type. Intelligibility entails constructibility, but not conversely. A type of situation may be constructible at some person's level of discrimination, but not coherently intelligible to him. On this basis, a logic of senses or truth-conditions for uses of expressions is developed, and a logic of interpretations of uses. The central notions of Naessian semantics are defined: ambiguity and direction of interpretation, level of discrimination and depth of intention. (shrink)

Describing, understanding, and explaining subjective experience in depression is a great challenge for psychopathology. Attempts to uncover neurobiological mechanisms of those experiences are in need of theoretical concepts that are able to bridge phenomenological descriptions and neurocognitive approaches, which allow us to measure indicators of those experiences in quantitative terms. Based on our own on going work with patients who suffer from depersonalization disorder and describe their experience as flat and detached from self, body, and world, we introduce the idea (...) of phenomenal depth as such a concept. Phenomenal depth is conceptualized as a dimension inherent to all experiences, describing the relatedness of one's self with one's mental processes, body, and the world. More precisely, it captures the experience of this relatedness and embeddedness of one's experiences, and it is thus a meta- or secondorder experience. The psychopathology of DPD patients can be understood very generally as an instance of reduced phenomenal depth. We will argue that similar experiences in depression can also be understood as a reduction in phenomenal depth. We relate those ideas to neurocognitive studies of perception, emotion regulation, and the idea of predictive coding. Finally, we will speculate about possible neurobiological underpinnings of the dimension of phenomenal depth. (shrink)

We develop and apply a multi-dimensional conception of explanatory depth towards a comparative analysis of inflationary and bouncing paradigms in primordial cosmology. Our analysis builds on earlier work due to Azhar and Loeb (2021) that establishes initial condition fine-tuning as a dimension of explanatory depth relevant to debates in contemporary cosmology. We propose dynamical fine-tuning and autonomy as two further dimensions of depth in the context of problems with instability and trans-Planckian modes that afflict bouncing and inflationary (...) approaches respectively. In the context of the latter issue, we argue that the recently formulated trans-Planckian censorship conjecture leads to a trade-off for inflationary models between dynamical fine-tuning and autonomy. We conclude with the suggestion that explanatory preference with regard to the different dimensions of depth is best understood in terms of differing attitudes towards heuristics for future model building.

Although clinical interpretation originated with Freud, the latter's positivist preference for purely observational methods made him ambivalent toward interpretive methods. According to Rubovits-Seitz, the legacy of Freud's positivism still pervades clinical thinking and interferes with progress in investigating and improving interpretive methods. He reviews the paradigm shift in general science from positivism to postpositivism by way of demonstrating the compatibility of interpretive inquiry with a postpositivist approach. Post-Freudian models of clinical interpretation are evaluated, andclinical methods of interpretation are compared with (...) interpretive approachesin nonclinical fields. A detailed discussion of the neglected problem ofjustifying interpretations incorporates evaluations of specific justifyingprocedures and a case report illustrating applications of such methods. Thework concludes with a consideration of common but avoidable errors in clinicalinterpretation along with remedial strategies for dealing with them. Following _Depth-Psychological Understanding, _clinicians may no longer take for granted the interpretive process and the accuracy of their own interpretations. Rubovits-Seitz's scholarly survey marks a major advance in comprehending the methodology of clinical interpretation and in setting forth both the problems and promise of interpretive methods.

The interpretation given by Craik and Lockhart of the findings by Hyde and Jenkins involving supposed depth of incidental-task processing on subsequent word recall is brought into question by the tenets of logical learning theory. It is shown that Craik and Lockhart overlooked the possible role of oppositionality in this research. An alternative explanation relying on an oppositional context and predication is offered. Two experiments present evidence supporting the hypothesis that oppositionality in an incidental task facilitates subsequent word recall (...) . In both experiments, the importance of taking a subject's meaningful understanding of the task instruction into consideration is highlighted. The discussion contrasts Boolean "binary" disjunction with the logic of oppositionality. It is shown how oppositionality allows us to conceptualize a testable theory of human agency. (shrink)

Mathematicians use the word ‘deep’ to convey a high appreciation of a concept, theorem, or proof. This paper investigates the extent to which the term can be said to have an objective character by examining its first use in mathematics. It was a consequence of Gauss's work on number theory and the agreement among his successors that specific parts of Gauss's work were deep, on grounds that indicate that depth was a structural feature of mathematics for them. In contrast, (...) French mathematicians had a less structural, more problem-oriented approach to mathematics and did not speak of depth so readily. (shrink)

The paper essentially shows that the paraconsistent logicDR satisfies the depth relevance condition. The systemDR is an extension of the systemDK of [7] and the non-triviality of a dialectical set theory based onDR has been shown in [3]. The depth relevance condition is a strengthened relevance condition, taking the form: If DR- AB thenA andB share a variable at the same depth, where the depth of an occurrence of a subformulaB in a formulaA is roughly the (...) number of nested ''s required to reach the occurrence ofB inA. The method of proof is to show that a model structureM consisting of {M 0 , M1, ..., M}, where theM i s are all characterized by Meyer''s 6-valued matrices (c. f, [2]), satisfies the depth relevance condition. Then, it is shown thatM is a model structure for the systemDR. (shrink)

The first part of the paper is devoted to surveying the remarks that philosophers and mathematicians such as Maddy, Hardy, Gowers, and Zeilberger have made about mathematical depth.

The idea of measuring depth by the depth and bushiness of the proof is considered, and compared to the related notion of the depth of a chess (...) combination. (shrink)

In this paper, I will consider the repercussions that epistemic contextualism has on capturing the distinctive value of knowledge. I will argue that the way that contextualist views capture the value of knowledge depends on the depth of the contextualism involved. To do so, I distinguish between superficial and deep contextualism, and I show how the latter is forced to contextualist epistemic value in a way the former is not. However, I then argue that if the superficial contextualist view (...) does not contextualise epistemic value, it would nevertheless fail to properly capture the value of knowledge. If epistemic contextualism is true, then epistemic value should be contextualised. (shrink)

In Depth Psychology, Interpretation, and the Bible Brayton Polka shows that the ideas central to Freud's major texts can be truly understood only in light of a theory of interpretation whose ontology is consistent with biblical values. Polka argues that only this hermeneutic frees Freud's insight into the phenomenology of the unconscious from his contradictory metapsychology.

.Deep disagreements are those involving a disagreement about (relatively) fundamental epistemic principles. This paper considers the bearing of testimonial injustice, in Miranda Fricker’s sense, on the depth of disagreements, and what this can teach us about the nature and significance of deep disagreements. I start by re-evaluating T. J. Lagewaard’s recent argument that disagreements about the nature, scope, and impact of oppression will often be deepened by testimonial injustice, since the people best placed to offer relevant testimony will be (...) subject to testimonial injustice, pushing the disagreement into one about the bearing of certain epistemic sources on the original debate. I take issue with this last step, but I build on the argument to bring attention to unappreciated and worrying ways in which prejudices can make a disagreement deep in ways that can be hidden from one or more of the participants and from observers. Finally, I revisit some of the ways that deep disagreement has been thought to be problematic for the proper functioning of a democracy, and I examine whether the kinds of hidden deep disagreements I argue for in the paper make these problems any worse, concluding that they likely do.

Two experiments were performed to explore the mechanisms of human 3D shape perception. In Experiment 1, the subjects’ performance in a shape constancy task in the presence of several cues (edges, binocular disparity, shading and texture) was tested. The results show that edges and binocular disparity, but not shading or texture, are important in 3D shape perception. Experiment 2 tested the effect of several simplicity constraints, such as symmetry and planarity on subjects’ performance in a shape constancy task. The 3D (...) shapes were represented by edges or vertices only. The results show that performance with or without binocular disparity is at chance level, unless the 3D shape is symmetric and/or its faces are planar. In both experiments, there was a correlation between the subjects’ performance with and without binocular disparity. Our study suggests that simplicity constraints, not depth cues, play the primary role in both monocular and binocular 3D shape perception. These results are consistent with our computational model of 3D shape recovery. (shrink)

This article considers the popular thesis that a more proportional relationship between a cause and its effect yields a more abstract causal explanation of that effect, which in turn produces a deeper explanation. This thesis is taken to have important implications for choosing the optimal granularity of explanation for a given explanandum. In this article, I argue that this thesis is not generally true of probabilistic causal relationships. In light of this finding, I propose a pragmatic, interest-relative measure of explanatory (...) depth. This measure uses a decision-theoretic model of information pricing to determine the optimal granularity of explanation for a given explanandum, agent, and decision problem. (shrink)

Individualists claim that wide explanations in psychology are problematic. I argue that wide psychological explanations sometimes have greater explanatory power than individualistic explanations. The aspects of explanatory power I focus on are causal depth and theoretical appropriateness. Reflection on the depth and appropriateness of other wide explanations of behavior, such as evolutionary explanations, clarifies why wide psychological explanations sometimes have more causal depth and theoretical appropriateness than narrow psychological explanations. I also argue for the rejection of eliminative (...) materialism. (shrink)

The concept of depth is central to Merleau-Ponty’s phenomenology and informed not only his philosophy of perception but also his thinking about psychology, art and politics. This article traces the ways the notion of depth appears in Merleau-Ponty’s thinking in these fields, contrasting it with Husserl’s own phenomenological investigations. The article starts with a comparison of the function of perception in Husserl’s phenomenology and then proceeds with an analysis of how the issue of depth reappears in Merleau-Ponty’s (...) phenomenology of perception, phenomenology of art and political philosophy. I argue that while Husserl’s approach to phenomenology led him to analyses of aesthetics stemming from works of art as random examples, and to non-participation in politics, Merleau-Ponty’s phenomenology leads to the opposite approach, inviting concrete criticism in art and active participation in politics. It is argued that Merleau-Ponty’s approach is more philosophically consistent. The choice of particular works of art, and the particular political engagements, can retrospectively clarify the transcendental phenomenological investigations themselves. (shrink)

Some notion ofcompassion must play a central role in conceiving of a true process psychology. In Whitehead’s metaphysics, “feeling the feelings of others” is how reality itself is constructed. By placing primitive feeling at the heart ofperception, experience, and the nature of reality, process philosophy helps psychology envision compassion as a way of connecting directly to the depths of others, of nature, and of ourselves. This paper focuses on some deeper experiences of compassion, as elucidated by transpersonal psychology, and how (...) these spiritual experiences might be accessed and utilized in these challenging times.

This article interrogates the persistence of critical frameworks informed by depth-models of hermeneutics, and the repercussions the equation of “depth” with meaningfulness has for the appreciation of the “shallow” aesthetics of post-classical action cinema. Oppositions such as depth/surface, body/mind, and proximity/distance associated with a hermeneutics of depth are not neutral, but rather exist in a “violent hierarchy”. This ensures that works or styles that foreground surface are automatically deemed to be meaningless. One influential example of this (...) logic is Fredric Jameson's dismissal of postmodern superficiality in favour of modernist depth. In contrast, this article will explore alternative models of postmodern superficiality. Taking up Catherine Constable's reading of Linda Hutcheon, I will endeavour to demonstrate the benefits of adopting a postmodern critical perspective when engaging with texts that resist or problematise depth-models.

Autism and Asperger syndrome are psychiatric conditions diagnosed primarily on the basis of deficits and problems in social behaviour; interaction and communication. At present the explanation of these behavioural features is dominated by three cognitive models. However, it is a characteristic of each of these models that they only explain a sub-set of the overall features.The aim of this paper is to suggest an alternative conceptual theory of autism and Asperger syndrome that unites the current three models. Thus, the aim (...) is to situate the existing models as special cases of the one being proposed here. This alternative conceptualisation draws heavily on distinctions and ideas present in the philosophy of science, most especially in the area of critical realism. Central to the theory is the idea that the core “problem” in autism and Asperger syndrome concerns ontological depth. More specifically, that people with these conditions find it difficult to cope with phenomena characterised by depth , open systems and high internal relationality. (shrink)

ABSTRACTCritical realism's insight into depth ontology creates the possibility for re-imagining sociology as a science of the social world. However, critical realism has yet to gain a strong foothold in sociological analysis. Challenging the available criticism of critical realism, I argue that its main flaw is its inability to draw an appropriate epistemological strategy from its insights into depth ontology. I propose that this limitation can be overcome when we anchor the depth ontology of critical realism to (...) the two-step epistemological strategies of Bourdieu's field theory: first, objectifying common sense to develop a scientific model of social structure; and second, objectifying the scientific point of view to re-introduce common sense in the scientific model of social structure. I argue that by anchoring the ontological insights of critical realism to the epistemological strategies of field theory, we can create the long-sought core around which sociology can progress as a science of the social world.

An explanation of the seeing of depth both in reality and in pictures requires a dual content theory of visual recognition. In addition, there are two necessary conditions on genuine seeing of depth-related content. First, the right kinds of dependence relations must hold between a physical picture, its content and its perceiver, and second, the perceiver must be in an appropriate, functionally defined perceptual state.

Wilhelm Stekel was an Austrian physician and psychologist and one of Freud’s earliest followers. This title, originally published in 1921, was the author’s favourite of his own work.

This paper examines Margaret Cavendish’s ecological views and argues that, in the Appendix to her final published work, Grounds of Natural Philosophy (1668), Cavendish is defending a normative account of the way that humans ought to interact with their environment.

Since the late 19th century, when the “new science” of psychology and interest in esoteric and occult phenomena converged – leading to the “discovery” of the unconscious – the dual disciplines of depth psychology and mysticism have been wed in an often unholy union.

Chapters include inquiries into the nature of self and consciousness, questions regarding the status and limits of mysticism and mystical phenomenon, and approaches to these topics from multiple depth psychological traditions.

Few would disagree that depth is an admirable, highly desirable, and yet rare quality. One would expect to find, therefore, that much has been written on the subject. But this is not so. Perhaps the topic appears forbidding, because the nature of depth is itself a deep and difficult question, since it forces those who ask it to decide what is ultimately worth caring about. Be that as it may, I shall venture on to this rarely explored ground. (...) My strategy is to begin with some introductory remarks about depth in general and about moral depth as a particular form of it; then discuss Sophocles' dramatic treatment of the development of Oedipus toward, as I shall interpret it, greater depth; and then go on to formulate a more discursive account based on Sophocles' poetic intimations.
