The notion of transgenerational community is usually based on two diachronic interactions. The first interaction consists of present generations taking up the legacy (not only economic, but also institutional, artistic, cultural, and so forth) of past generations and giving it continuity, exercising a form of active agency. The second interaction occurs when present generations pass on their legacy to future generations. This is supposed to expand the boundaries of the community in a transgenerational sense (both backward- and forward-looking). In this (...) article we argue that the transgenerational community can be grounded on a different ontological insight: future generations play the role of fictional actors for present generations, i.e., present generations entertain a present-time interaction with future generations, insofar as future generations are functional for the realization of transgenerational actions. This lays the foundations for more solid community-based bonds of intergenerational justice. (shrink)

In this paper, we introduce the concept of N-dimensional generalized Minkowski space, i.e., a space endowed with a metric tensor, whose coefficients do depend on a set of non-metrical coordinates. This is the first of a series of papers devoted to the investigation of the Killing symmetries of generalized Minkowski spaces. In particular, we discuss here the infinitesimal-algebraic structure of the space-time rotations in such spaces. It is shown that the maximal Killing group of these spaces is the direct product (...) of a generalized Lorentz group and a generalized translation group. We derive the explicit form of the generators of the generalized Lorentz group in the self-representation and their related, generalized Lorentz algebra. The results obtained are specialized to the case of a 4-dimensional, “deformed” Minkowski space \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $${\widetilde M}$$ \end{document}4, i.e., a pseudoeuclidean space with metric coefficients depending on energy.

Two experiments were conducted to test a prediction of the Kosslyn & Shwartz computer simulation model of mental image processing. According to this model, more complex images require more time to form because parts are placed sequentially, and larger images require more time to form than smaller ones because more parts are placed. If these accounts are correct, then the advantage of forming a small image (i.e., one that seems to subtend a smaller visual angle) should be greater for more (...) complex objects because the difference in number of parts imaged at the two sizes will be greater than with simpler objects. This prediction was confirmed only when subjects were not motivated to form highly elaborated images at small sizes. When subject tried to include all details, it actually took longest to form images of complex objects at small sizes. Both of these results support the central assumption of the Kosslyn‐Shwartz model, namely the existence of a fixed resolution analog spatial medium. (shrink)

What I call the unfelt in society refers to different ways in which certain events or conditions fail to evoke affective responses or give rise to merely sporadic or toned-down modes of emotive concern. This is evident in public (non)responses to the ecological crisis in the Global North. I sketch an approach to the unfelt, drawing on work in phenomenology and on the situated affectivity approach. I focus on structural apathy as the condition of spatial, social, and cognitive-affective distance from (...) the devastation and suffering caused by capitalist modes of living. Most members of affluent societies live their lives spatially and ‘existentially’ removed from the dehumanizing living conditions of those whose exploited labor and (stolen) land enable and sustain that affluence. The resulting apathy amounts to a constitutional inability to grasp, fathom, and sympathize with the plight of those who are forced to endure those conditions. I hold that structural apathy is an underdiscussed baseline of affective injustice. Its analysis can generate insights into the conditions that make forms of affective injustice so pervasive and seemingly ‘natural’ in Western modernity. While the present text broadly contributes to the debate on affective injustice, it also voices some reservations about this debate and its guiding notion. (shrink)

The structural-parametric synthesis of neural networks of deep learning, in particular convolutional neural networks used in image processing, is considered. The classification of modern architectures of convolutional neural networks is given. It is shown that almost every convolutional neural network, depending on its topology, has unique blocks that determine its essential features, Residual block, Inception module, ResNeXt block. It is stated the problem of structural-parametric synthesis of convolutional neural networks, for the solution of which it is proposed to use a (...) genetic algorithm. The genetic algorithm is used to effectively overcome a large search space: on the one hand, to generate possible topologies of the convolutional neural network, namely the choice of specific blocks and their locations in the structure of the convolutional neural network, and on the other hand to solve the problem of structural-parametric synthesis of convolutional neural network of selected topology. The most significant parameters of the convolutional neural network are determined. An encoding method is proposed that allows to repre- sent each network structure in the form of a string of fixed length in binary format. After that, several standard genetic operations were identified, i.e. selection, mutation and crossover, which eliminate weak individuals of the previous generation and use them to generate competitive ones. An example of solving this problem is given, a database of patients with thyroid disease was used as a training sample. (shrink)

On the level of existential structure, “Shengsheng Buxi” unfolds an existential structure different from Heidegger’s “being-in-the-world”. This paper calls it “being-between-the-generations”. Through this existential structure, it reveals many aspects which Heidegger ignored in his existential analysis. The existence of “I” between generations is, first of all, a conjunction of generations, “this body” has its own origin. Its original facing the Other is to love his/her parents, and showing the structure of “being-together-with-the-generations” in filial piety; family implements the existence of “inheritance”, (...) thus gaining its ontological status in this structure. The state of mood in generations shows the “Enjoyment-at-home” of this-body; at the same time, being-between-the-generations also makes “learning” and “teaching” indispensable and essential moments in the existential structure, and makes the “Project” of “trans-generations” possible. The “historicity” formed by “generations” has an impact on this. Ultimately, in the memorial ceremony of “death of parents and ancestors”, it builds the structure of “being-together-with-the-generations” within a family, and maintains the dimension of transcendence, in the way of filial piety, whose nature is revealed in The Analects as “Tribute to the death of parents and keeping memory of ancestors” (慎終追遠).

In this article, I present the structural consequences generated by the continuous and systematic epistemic injustices carried out in certain communities or institutions. These injustices contribute to building a structure of silencing, denial of epistemic authority, cover-up and impunity. The importance of the normative aspect that guides the reflections about these injustices will be exposed in two senses: on the one hand, insofar as it is necessary to have criteria that allow establishing the truth in the background of evaluation (...) of epistemic injustices and, on the other, in the sense of specifying how systematically attempting against it produces almost irreversible epistemic damage and guarantees the perpetuation of the structure. It will be shown how this happens within the framework of a powerful institution such as the Catholic Church, which has exhibited a pattern of testimonial injustices and the cover-up of abuses within it for decades.

I argue that the ability to compute phrase structure grammars is indicative of a particular kind of thought. This type of thought that is only available to cognitive systems that have access to the computations that allow the generation and interpretation of the structural descriptions of phrase structure grammars. The study of phrase structure grammars, and formal language theory in general, is thus indispensable to studies of human cognition, for it makes explicit both the unique type of human thought and (...) the underlying mechanisms in virtue of which this thought is made possible.

Oxygenic photosynthesis is the principal producer of both oxygen and organic matter on earth. The primary step in this process—the conversion of sunlight into chemical energy—is driven by four multi‐subunit membrane protein complexes named photosystem I, photosystem II, cytochrome b6f complex and F‐ATPase. Photosystem I generates the most negative redox potential in nature and thus largely determines the global amount of enthalpy in living systems. The recent structural determination of PSI complexes from cyanobacteria and plants sheds light on the evolutionary (...) forces that shaped oxygenic photosynthesis. The fortuitous formation of our solar system in a space plentiful of elements, our distance from the sun and the long time of uninterrupted evolution enabled the perfection of photosynthesis and the evolution of advanced organisms. The available structural information complements the knowledge gained from genomic and proteomic data to illustrate a more precise scenario for the evolution of life systems on earth.

Should we remain neutral between our interests and those of future generations? Or are we ethically permitted or even required to depart from neutrality and engage in some measure of intergenerational discounting? This Article addresses the problem of intergenerational discounting by drawing on two different intellectual traditions: the social welfare function (“SWF”) tradition in welfare economics, and scholarship on “prioritarianism” in moral philosophy. Unlike utilitarians, prioritarians are sensitive to the distribution of well-being. They give greater weight to well-being changes affecting (...) worse-off individuals. Prioritarianism can be captured, formally, through an SWF which sums a concave transformation of individual utility, rather than simply summing unweighted utilities in utilitarian fashion. The Article considers the appropriate structure of a prioritarian SWF in intergenerational cases. The simplest case involves a fixed and finite intertemporal population. In that case, I argue, policymakers can and should maintain full neutrality between present and future generations. No discount factor should be attached to the utility of future individuals. Neutrality becomes trickier when we depart from this simple case, meaning: (1) “non-identity” problems, where current choices change the identity of future individuals; (2) population-size variation, where current choices affect not merely the identity of future individuals, but the size of the world’s future population (this case raises the specter of what Derek Parfit terms “the repugnant conclusion,” i.e., that dramatic reductions in the average level of individual well-being might be compensated for by increases in population size); or (3) an infinite population. The Article grapples with the difficult question of outfitting a prioritarian SWF to handle non-identity problems, population-size variation, and infinite populations. It tentatively suggests that a measure of neutrality can be maintained even in these cases. (shrink)

The concept of “structural injustice” has a long intellectual lineage, but Iris Marion Young popularised the term in her late work in the 2000s. Young’s theory tapped into the zeitgeist of the time, providing a credible way of thinking about transnational and domestic injustices, illuminating the importance of political, economic and social structures in generating injustice, theorising the role of individuals in perpetuating structural injustice, and the responsibility of everyone to try to correct it. Young’s theory has inspired secondary (...) and novel research. In this paper, I outline the main topics in this recent literature: what structural injustice is, responsibility for structural injustice, acting on responsibility, avoiding responsibility, and historical injustice. I conclude by noting how the influence of structural injustice theory is spreading beyond the confines of political theory. Any field that is concerned with structural inequalities, disadvantage, or oppression, can utilize structural injustice theory. (shrink)

The aim of this article is to present study results concerning the structure of teacher Machiavellianism. Machiavellianism was researched extensively throughout the last 40 years as a personality feature comprising traits related to leadership manipulation tactics. Psychology describes Machiavellianism as a part of the universal model called “the dark triad of personality” alongside with subclinical narcissism, subclinical psychopathy and low empathy. The teacher Machiavellianism model presented in this article, as opposed to the universal models, strongly accentuates the context-specific variables related (...) to the organization of life in a school, alongside with personality variables. To achieve a new insight into the mechanism of how teacher Machiavellianism is generated, structural equation modeling was used, which incorporates personality variables such as: self-effi cacy, disposition for gratitude, values, one’s personal resources, professional burnout, alongside context-specific variables like: organizational culture, work attitude, tenure and specialization in the tasks performed. Results of two studies are shown, discussing the empirical structure of teacher Machiavellianism components in relation to the initial theoretical model. (shrink)

In this paper we study an alternative approach to the concept of abstract logic and to connectives in abstract logics. The notion of abstract logic was introduced by Brown and Suszko —nevertheless, similar concepts have been investigated by various authors. Considering abstract logics as intersection structures we extend several notions to their κ -versions, introduce a hierarchy of κ -prime theories, which is important for our treatment of infinite connectives, and study different concepts of κ -compactness. We are particularly (...) interested in non-topped intersection structures viewed as semi-lattices with a minimal meet-dense subset, i.e., with a minimal generator set. We study a chain condition which is sufficient for a minimal generator set, implies compactness of the logic, and in regular logics is equivalent to compactness of the consequence relation together with the existence of a inconsistent set, where κ is the cofinality of the cardinality of the logic. Some of these results are known in a similar form in the context of closure spaces, we give extensions to intersection structures and to big cardinals presenting new proofs based on set-theoretical tools. The existence of a minimal generator set is crucial for our way to define connectives. Although our method can be extended to further non-classical connectives we concentrate here on intuitionistic and infinite ones. Our approach leads us to the concept of the set of complete theories which is stable under all considered connectives and gives rise to the definition of the topological space of the logic. Topological representations of abstract logics by means of this space remain to be further investigated. (shrink)

Causal structure learning algorithms have focused on learning in ”batch-mode”: i.e., when a full dataset is presented. In many domains, however, it is important to learn in an online fashion from sequential or ordered data, whether because of memory storage constraints or because of potential changes in the underlying causal structure over the course of learning. In this paper, we present TDSL, a novel causal structure learning algorithm that processes data sequentially. This algorithm can track changes in the generating causal (...) structure or parameters, and requires significantly less memory in realistic settings. We show by simulation that the algorithm performs comparably to batch-mode learning when the causal structure is stationary, and significantly better in non-stationary environments. (shrink)

Living systems are characterized as self-generating and self-maintaining systems. This type of characterization allows integration of a wide variety of detailed knowledge in biology.The paper clarifies general notions such as processes, systems, and interactions. Basic properties of self-generating systems, i.e. systems which produce their own parts and hence themselves, are discussed and exemplified. This makes possible a clear distinction between living beings and ordinary machines. Stronger conditions are summarized under the concept of self-maintenance as an almost unique character of living (...) systems. Finally, we discuss the far-reaching consequences that the principles of self-generation and self-maintenance have for the organization, structure, function, and evolution of single- and multi-cellular organisms.

Human language is a salient example of a neurocognitive system that is specialized to process complex dependencies between sensory events distributed in time, yet how this system evolved and specialized remains unclear. Artificial Grammar Learning (AGL) studies have generated a wealth of insights into how human adults and infants process different types of sequencing dependencies of varying complexity. The AGL paradigm has also been adopted to examine the sequence processing abilities of nonhuman animals. We critically evaluate this growing literature (...) in species ranging from mammals (primates and rats) to birds (pigeons, songbirds, and parrots) considering also cross‐species comparisons. The findings are contrasted with seminal studies in human infants that motivated the work in nonhuman animals. This synopsis identifies advances in knowledge and where uncertainty remains regarding the various strategies that nonhuman animals can adopt for processing sequencing dependencies. The paucity of evidence in the few species studied to date and the need for follow‐up experiments indicate that we do not yet understand the limits of animal sequence processing capacities and thereby the evolutionary pattern. This vibrant, yet still budding, field of research carries substantial promise for advancing knowledge on animal abilities, cognitive substrates, and language evolution. (shrink)

This paper proposes an integrated-structure notion of interlevel emergence, from a dynamic relational ontological perspective. First, I will argue that only the individualist essentialism of atomistic metaphysics can block the possibility of interlevel emergence. Then I will show that we can make sense of emergence by recognizing the formation of structures of transformative and interdependent causal relations in the generation and development of a particular class of mereological complexes called integrated systems. Finally, I shall argue that even though the (...) emergent structural attributes of such systems are not micro-determined nor micro-reducible, they can still be accounted for by an interlevel integrative neo-mechanistic form of explanation.

Despite their status as high-income food producing nations, children and their caregivers, both in the United States (U.S.) and Australia can experience food insecurity. Nutrition researchers formed a joint U.S.-Australia collaboration to help advance food security for households with young children aged 0–5 years. This study investigated food insecurity from the perspective of caregivers, especially their perceptions of the impact of food insecurity on their own childhood, their current life, and for the children in their care. Semi-structured interviews were conducted (...) from July to September 2020 during the COVID-19 pandemic. Participants were recruited in Omaha, Nebraska, U.S. (_n_ = 19) and Melbourne, Victoria, Australia (_n_ = 22), during periods of stay-at-home public health orders. These two case study sites enabled an exploration of some universal, and some context-specific, social, economic, and health conditions that buffer, or exacerbate, food insecurity for families in these neo-liberal political settings. An inductive thematic analysis was conducted and established six themes:_growing up poor_, _lessons learned_,_ feeding a family amidst a pandemic_,_ caregiver coping strategies_, _food security in the early years_ and _protecting (young) children_. Perspectives on local anti-hunger strategies were organized to outline participant’s preferred solutions. Household food insecurity is conceptualized in public policy in the U.S. and Australia as a short-term crisis for people, justifying austere, time-limited and patchwork solutions. A narrative of caregivers’ lived experience of food insecurity suggests that it is inter-generational, and exacerbated by a food system shock (i.e., COVID-19). These findings from two varying cities and nations offer a different conceptualization of the timespan and nature of the phenomenon of food insecurity, challenging a dominant policy narrative and highlighting the inadequacy of current so-called solutions.

Some accounts of mental content represent the objects of belief as structured, using entities that formally resemble the sentences used to express and report attitudes in natural language; others adopt a relatively unstructured approach, typically using sets or functions. Currently popular variants of the latter include classical and neo-classical propositionalism, which represent belief contents as sets of possible worlds and sets of centered possible worlds, respectively; and property self-ascriptionism, which employs sets of possible individuals. I argue against their contemporary proponents (...) that all three views are ineluctably plagued by generation gaps: they either overgenerate beliefs, undergenerate them, or both. (shrink)

The sensorimotor theory of vision and visual consciousness is often described as a radical alternative to the computational and connectionist orthodoxy in the study of visual perception. However, it is far from clear whether the theory represents a significant departure from orthodox approaches or whether it is an enrichment of it. In this study, I tackle this issue by focusing on the explanatory structure of the sensorimotor theory. I argue that the standard formulation of the theory subscribes to the same (...) theses of the dynamical hypothesis and that it affords covering-law explanations. This however exposes the theory to the mere description worry and generates a puzzle about the role of representations. I then argue that the sensorimotor theory is compatible with a mechanistic framework, and show how this can overcome the mere description worry and solve the problem of the explanatory role of representations. By doing so, it will be shown that the theory should be understood as an enrichment of the orthodoxy, rather than an alternative. (shrink)

I‐J has been regarded as a polymorphic genetic marker controlled by a locus in the major histocompatibility complex (MHC) which is expressed only on functional T cells. However, this antigenic determinant has been found not to be directly encoded by the MHC gene per se but is somatically generated according to the MHC of the cellular environment during ontogeny. This explains the apparent linkage of I‐J to MHC, despite the failure to find the structural gene for I‐J within the (...) MHC. The I‐J paradox provides an instance of a polymorphism that does not follow the standard genetics of Mendelian structural genes. (shrink)

Although the idiom “genesis and structure” is usually associated with the rise of structuralism in the late 1950s and early 1960s, the two notions are arguably among the most persistent methods in the history of modern philosophy. This article outlines the emergence of “genetic epistemology” in the seventeenth century, when the seemingly antithetical character of the conceptual pair was reworked into a productive epistemological theory, especially in Descartes, Hobbes, Spinoza, and Leibniz, who increasingly used diachronic (genetic) narratives to explain the (...) synchronic (structural) features in their theories. Against Cassirer, I argue that it was Descartes rather than Hobbes who first presented structural issues genetically. In Descartes’ natural philosophy, his frequent claims that showing how a thing is produced reveals its true nature foreshadow precisely what Hobbes and Isaac Barrow later describe as causal definitions of geometric figures, in which the process of ideal generation by motion is what constitutes the very essence of a figure. I link this method to the historicizing discourse on origins in the Enlightenment and conclude by suggesting that there is a trace of Platonic idealism in genetic epistemology. (shrink)

This paper offers an overview of the ways agents might extend over time and the characteristic structure of extended human agency. Agency can extend in two distinct but combinable modes: the ontological, which gives rise to simple continuous agents; and the conceptual, which gives rise to agents who conceive of and care about distal times, and have minimal planning abilities. Our extended form of agency combines both. But we are still limited by the temporal locality in the operation of our (...) psychological and executive powers. To account for this locality, I introduce the notion of 'temporal selves,' as the loci of immediacy in the agent's determination of their psychology, conduct, and practical standpoint. I argue that the passage of time generates, by itself, the threat of temporal alienation from distant temporal selves. A genuinely extended agency requires temporal identification: the sharing, by separate temporal selves, of a temporally extended and integrated practical standpoint. This temporal identification cannot be produced simply by temporal identity as continuity. What is required is temporal identity in the mode of unity and integration. This identity does not precede temporal identification but is co-constituted with it. I offer a preliminary account of the structure of the units of integration for agents who aspire to persist in the mode of unity and integration. I close with a cautionary note: the complex structure of integration, although familiar in everyday life, is often missed by standard philosophical accounts, which tend to focus on simple models of extended agency.

Given an abstract logic L = L(Q i ) i ∈ I generated by a set of quantifiers Q i , one can construct for each type τ a topological space S τ exactly as one constructs the Stone space for τ in first-order logic. Letting T be an arbitrary directed set of types, the set $S_T = \{(S_\tau, \pi^\tau_\sigma)\mid\sigma, \tau \in T, \sigma \subset \tau\}$ is an inverse topological system whose bonding mappings π τ σ are naturally determined (...) by the reduct operation on structures. We relate the compactness of L to the topological properties of S T . For example, if I is countable then L is compact iff for every τ each clopen subset of S τ is of finite type and S τ is homeomorphic to $\underset{lim}S_T$ , where T is the set of finite subtypes of τ. We finally apply our results to concrete logics. (shrink)

In this paper, I introduce a special case of epistemic injustice that I call ‘structural contributory injustice’. This conception aims to capture some dimensions of how policy—separately from individual agential interactions—can generate epistemic injustice at a group level. I first locate the case within Kristie Dotson’s original conception of contributory injustice. I then consider one potential case of structural contributory injustice—namely, the policy problem of significant financial risk burden on students considering university in the USA. Finally, I consider potential policy (...) reforms in response to this injustice. (shrink)

The conflation of two fundamentally distinct issues has generated serious confusion in the philosophical and biological literature concerning the units of selection. The question of how a unit of selection of defined, theoretically, is rarely distinguished from the question of how to determine the empirical accuracy of claims--either specific or general--concerning which unit(s) is undergoing selection processes. In this paper, I begin by refining a definition of the unit of selection, first presented in the philosophical literature by William Wimsatt, (...) which is grounded in the structure of natural selection models. I then explore the implications of this structural definition for empirical evaluation of claims about units of selection. I consider criticisms of this view presented by Elliott Sober--criticisms taken by some (for example, Mayo and Gilinsky 1987) to provide definitive damage to the structuralist account. I shall show that Sober has misinterpreted the structuralist views; he knocks down a straw man in order to motivate his own causal account. Furthermore, I shall argue, Sober's causal account is dependent on the structuralist account that he rejects. I conclude by indicating how the refined structural definition can clarify which sorts of empirical evidence could be brought to bear on a controversial case involving units of selection. (shrink)

Sensations can occur in the absence of perception and yet be experienced ‘as if’ seen, heard, tasted, or otherwise perceived. Two concepts used to investigate types of these sensory-like mental phenomena (SLMP) are mental imagery and hallucinations. Mental imagery is used as a concept for investigating those SLMP that merely resemble perception in some way. Meanwhile, the concept of hallucinations is used to investigate those SLMP that are, in some sense, compellingly like perception. This may be a difference of degree. (...) Attempts to reliably differentiate between instances of each type of SLMP remain unresolved. Despite this, the concepts of mental imagery and hallucinations are each routinely used independently of the other. These uses are especially interesting in those published accounts of experiments where equivalent findings about the neuroanatomical correlates of SLMP are reported in support of diverging knowledge-claims about the role of SLMP in neurocognitive processes. This practice presents a puzzle. To examine one aspect of this puzzle, I compare the uses of these two scientific concepts in three ways: examining their roles in differentiating between types of SLMP; exploring how their respective historical developments intersect; and analysing their contributions in neuroimaging experiments. In presenting this series of comparative analyses, I will draw on three themes from historical, philosophical, and social studies of scientific practices: interest in material contributions to knowledge; accounts of how concepts are used in experiments; and explorations of the historical conditions within which current practices emerge. Building on this literature, my comparative analyses supports five related claims. My first claim is that the concepts of mental imagery and hallucinations are each used as independent tools in neuroimaging experiments. My second claim is that, as experimental tools, the concepts of mental imagery and hallucinations are each used for investigating discrete epistemic goals. My third claim is that there are implicit interdependent associations that structure the uses of these two concepts as tools for independently investigating these discrete epistemic goals in neuroimaging experiments. This third claim rests on my analyses of both past and present uses of each concept. Firstly, as seen in their intersecting histories, there are disciplined performances of using the concepts of mental imagery and hallucinations that carry-along shared associations about the mediating role of SLMP in thought. Secondly, these interdependent ‘mediator-view’ associations continue to structure the independent uses of each concept as a tool for investigating SLMP in pursuit of specific goals. Taking this further, my fourth claim is that recognising the structured uses of the concepts of mental imagery and hallucinations can help to account for how equivalent SLMP-neuro-correlates are generated in support of diverging knowledge-claims. Finally, my fifth claim is that the structured uses of these concepts as tools can contribute to experiments in ways analogous to, yet not equivalent with, the active contributions of material instruments. Bringing these claims together, I argue that the concepts of mental imagery and hallucinations operate as structured tools that can actively contribute to the knowledge generated by neuroimaging experiments. In presenting this argument I seek to demonstrate that examining the structured uses of concepts as tools can complement existing approaches to studying how the heterogeneous dynamics of experimental practices can come to contribute to scientific knowledge in unintended ways.

It has been common in contemporary philosophical logic to separate existence, essence and logic. I would like to reverse these separative tendencies. Doing so yields two theses, one about the existential basis of truth, the other about the essentialist basis of logic. The first thesis counters the common claim that both logical and essential truths-in short, structural truths-are existence-free. It is proposed that only real existences can generate essentialist and logical predications. The second thesis counters the common assumption that logic (...) is free of essentialist involvement. I propose the contrary-logical predications are to be explained as a special kind of essentialist attributions. (shrink)

According to the DP hypothesis, the merger of a determiner and a noun yields a determiner phrase (DP) rather than a noun phrase (nP). Focusing on Spanish, I defend the DP hypothesis but reject the notion that argumenthood is contingent upon a DP layer. Instead, I maintain that arguments can be as small as nP provided that they are c-commanded by a verb or a preposition, in which case the variables that they introduce are bound through a last-resort operation of (...) existential closure. I then consider the ways in which functional projections above nP shape the denotation of nominal arguments and adopt Borer’s (2005) view that a division phrase (DivP) is responsible for countability. Nonplural indefinite expressions can either have mass or singular readings depending on the determiner ("mucho tomate" 'much tomato' versus "un tomate" 'a tomato'), whereas nonplural definite expressions can have both mass and singular readings no matter the determiner ("el/este/mi tomate" 'the/this/my tomato'). I attribute the systematic ambiguity of nonplural definite expressions to the absence of DivP in their structure and the maximality operator that is a component of definiteness. -/- Throughout the thesis, I explore the formal representation of φ-features and how their semantic behaviour is conditioned by their syntactic position. I propose that gender features have consequences for interpretation when they are hosted by Panagiotidis’s (2019) animacy phrase (AnimP) but not by nP and extend this argument to number features on DivP versus nP, thereby eliminating the need for "interpretable" and "uninterpretable" versions of the same feature. As for pronouns, it is not immediately apparent where they are generated in Spanish because they are not mutually exclusive with the definite article ("nosotros los cocineros" 'we the chefs'). After upholding Höhn’s (2016, 2017) claim that pronouns originate in a dedicated person phrase (πP) in languages that use the definite article in pronoun-noun constructions, I address the issue of the third-person gap ("ellos los cocineros" 'they the chefs') and argue that third-person pronouns are forms that realize π, D, Div, Anim, and n, a configuration that prevents other material from occupying these same heads.

Most of this work is concerned with two theories that underlie cognitive science; theories which I call "the representational theory of intentionality" and "the computational theory of cognition" . While the representational theory of intentionality asserts that mental states are about the world in virtue of a representation relation between the world and the state, the computational theory of cognition asserts that humans and others perform cognitive tasks by computing functions on these representations. CTC draws upon a rich analogy between (...) the mind and digital computers, portraying cognizers as receiving input and generating outputs . ;Since researchers within cognitive science--especially within cognitive psychology, computer science, and philosophy of mind--share a common theoretic background in their adherence to the combination of RTI and CTC, what I call "computationalism" most of the work done in philosophy of mind has been aimed at either refuting or further articulating these two theories. This work is strongly within that tradition. ;RTI and CTC combine to create an explanatory framework for explanation in cognitive science. In this work, I seek to delineate the exact structure of this framework, to determine its components and their overall relationships. In my mind, this involves making implicit aspects of computational explanation explicit, providing an overall rationale for the various components and their relationships, and defending that rationale against criticism. ;In particular, the project of this work is to argue that computationalist explanations of cognition within cognitive science need to make appeals to both representation and knowledge; to distinguish the respective roles of knowledge and of representation in an overall picture of computational explanations, and to develop and argue for definitions of representation and knowledge that would allow those concepts to play their respective roles within computational explanations in cognitive science. ;The first half of this work , therefore, is devoted to theories of representation, especially to the need for, and role of representation in computational explanations. The first half of the work culminates in chapter three with a definition of representation and a picture of the structure of computational explanations. The second half of the project then becomes to generate a definition of knowledge that defines knowledge in non-epistemic language amenable to computationalism and that carries the epistemic burdens placed upon knowledge by its use in computational explanations, as well as to offer a limited defence of that definition within the framework of traditional epistemology.

Consumer boycotts have become a frequent form of social protest in the digital age. The corporate malpractices motivating them are varied, including environmental pollution, lack of minimum labour standards, severe mistreatment of animals, lobbying and misinformation campaigns, collaboration or complicity with illegitimate political regimes, and systematic tax evasion and tax fraud. In this article, I argue that organised consumer boycotts should be regarded as a legitimate and purposeful instrument for structural change, provided they conform to a number of normative criteria. (...) In order to show this, the practice and empirical context of consumer boycotts are first outlined. I then lay out and refute three general objections to this practice. Although each of these objections fails, their discussion generates insights concerning the normative standards with which boycotters must comply if they want their campaigns to be both legitimate and successful. These normative criteria are detailed along the lines of two guiding principles, proportionality and transparency. In the final step, I elaborate on structural change as the deeper purpose of consumer boycotts. (shrink)

Problem: Can communication emerge from the interaction of “self-referentially closed systems,” conceived as operating solely on the base of the “internal” output of their onboard means? Or in terms of philosophical conceptions: can communication emerge without (“outward” directed) “intention” or “will to be understood”? Method: Multi-agent simulation based on a conceptual analysis of the theory of social systems as suggested by Niklas Luhmann. Results: Agents that co-evolutionarily aggregate probabilities on how to cope with their environment can structurally couple and generate (...) a form of “eigenbehavior” that retrospectively (i.e., by an observer) might be interpreted as communication. Implications: The “intention” or the “will to be understood,” as prominently claimed to be indispensable in communication by theoreticians such as Jürgen Habermas, can be seen as a retrospective ascription to an emergent property of complex interaction. Constructivist content: The paper attempts to base constructivist reasoning on data generated in simulations. (shrink)

A monumental work of scholarship, consisting of thorough and comprehensive treatments of four relatively distinct motifs in the thought of the early Church Fathers. Part One deals with the origin of the problem of faith and reason, together with the various solutions proposed; Part Two treats the Trinity, the Logos, and Platonic Ideas; Part Three examines the three Christian "mysteries"--the Trinity, the Incarnation, and the generation of the Logos; and Part Four details the rise of the heresies, particularly gnosticism. This (...) is a work of exposition rather than of philosophical evaluation, but its scope and detail make it an indispensable starting-point for any future effort to appraise the thought of the early Church Fathers.--A. C. P. (shrink)

I choose this somewhat awkward title because it seems to me to be necessary to insist on the uncertainty, the lack of structure, in the connection between the generations. This is due to a large extent of course to the multiple character of the expression ‘generation’ itself; it is a word with such a tangle of related and overlapping meanings attached to it that it is surprising to find that it goes on being used without qualificatory adjectives. Let us look (...) at a few of the notions which ‘generation’ covers. (shrink)

A recent trend in bioethics has highlighted the decisive role that solidarity plays in global health. However, given the impact and extent of the effects of climate change, which reach beyond present generations, it is important to consider whether this concept can be applied intergenerationally. Does it make sense to talk about solidarity with future generations? The objective of this article is to explore ‘amplified solidarity’, a new concept of solidarity that explains our obligations towards the health and quality of (...) life of future generations. The analysis of this concept is structured as follows: I first establish the moral relevance of future people and then investigate the traits of amplified solidarity, its challenges, and its relationship with other key principles. I propose that amplified solidarity needs both a critical imagination to be projected towards the future and an institutional framework to correct health injustices across an intergenerational timescale. Solidarity forms a potent triangular constellation with responsibility and justice to fight against global and intergenerational injustices. (shrink)

Reflecting on the past is often a critical ingredient for successful learning. The current research investigated how counterfactual thinking, reflecting on how prior experiences might have been different, motivates effective learning from these previous experiences. Specifically, we explored how the structure of counterfactual reflection – their additive (‘‘If only I had”) versus subtractive (‘‘If only I had not”) nature – influences performance in dyadic-level strategic interactions. Building on the functionalist account of counterfactuals, we found across two experiments that generating additive (...) counterfactuals about a previous negotiation produced an advantage for negotiators over their previous performance compared to subtractive counterfactuals, both in terms of obtaining value for oneself and conceiving creative agreements. Additive counterfactuals enabled negotiators to more effectively extract lessons from past experiences to improve their current negotiation performance. (shrink)

This article proposes a way of understanding Kantianism, act-utilitarianism and some other important ethical theories according to which they are all versions of the same kind of theory, sharing a common structure. I argue that this is a profitable way to understand the theories discussed. It is charitable to the theories concerned; it emphasizes the common ground between them; it gives us insights into the differences between them; and it provides a method for generating new ethical theories worth studying. The (...) article briefly discusses the relationship between these ideas and some other recent proposals that emphasize the common ground between Kantianism and versions of consequentialism.

The performance of deep Neural Networks (NNs) in the text (ChatGPT) and image (DALL‐E2) domains has attracted worldwide attention. Convolutional NNs (CNNs), Large Language Models (LLMs), Denoising Diffusion Probabilistic Models (DDPMs)/Noise Conditional Score Networks (NCSNs), and Graph NNs (GNNs) have impacted computer vision, language editing and translation, automated conversation, image generation, and social network management. Proteins can be viewed as texts written with the alphabet of amino acids, as images, or as graphs of interacting residues. Each of these perspectives suggests (...) the use of tools from a different area of deep learning for protein structural biology. Here, I review how CNNs, LLMs, DDPMs/NCSNs, and GNNs have led to major advances in protein structure prediction, inverse folding, protein design, and small molecule design. This review is primarily intended as a deep learning primer for practicing experimental structural biologists. However, extensive references to the deep learning literature should also make it relevant to readers who have a background in machine learning, physics or statistics, and an interest in protein structural biology.

Kind representations, concepts like table, triangle, dog, and planet, underlie generic language. Here, we investigate the formal structure of kind representations—the structure that distinguishes kind representations from other types of representations. The present studies confirm that participants distinguish generic‐supporting properties of individuals (e.g., this watch is made of steel) and accidental properties (e.g., this watch is on the nightstand). Furthermore, work dating back to Aristotle establishes that only some generic‐supporting properties bear a principled connection to the kind, that is, are (...) true of an individual by virtue of its being a member of a specific kind (e.g., telling time for a watch). The present studies tested the hypothesis that principled connections are part of the formal structure of kind representations. Specifically, they tested whether they structure a newly learned kind representation. Experiment 1 found that introducing a property of a newly encountered novel kind in any one of four linguistic frames that provide evidence that a property has a principled connection to a kind (e.g., “It has fur because it is a blick”) led participants to infer a different conceptual consequence of principled connections (i.e., “There is something wrong with this blick, which does not have fur”) for which they had no direct evidence. Two introduction frames that provided no evidence for principled connections (e.g., “Almost all blicks have fur”) did not generate the same consequence. Experiment 2 found that all of the targeted properties were generic licensing, irrespective of the introduction frame. That the distinction between properties that bear principled connections to their kinds, and merely generic‐supporting properties structures novel kind representations, provides strong evidence that this distinction is part of the formal structure of kind representations.

λ-calculi are of interest to logicians and computer scientists but have largely escaped philosophical commentary, perhaps because they appear narrowly technical or uncontroversial or both. I argue that even within logic λ-expressions need to be understood correctly, as functors signifying functions in intension within a categorical or typed language. λ-expressions are not names but pure viable binders generating functors, and as such they are of use in giving explicit definitions. But λ is applicable outside logic and computer science, anywhere where (...) the notions of complex whole, substitution, abstraction and structure make sense. To illustrate this, two domains are considered. One is somewhat frivolous: the study of flags; the other is very serious: manufacturing engineering. In each case we can employ λ-abstraction to describe substitutions within a structure, and in the latter case there is even a practical need for such a notation. (shrink)

There is a long-standing and rarely contested view that Gricean conversational reasoning—the kind of reasoning that supports the identification of conversational implicatures—cannot produce pragmatically generated modification of the contents of embedded clauses. The goal of this paper is to argue against this view: to argue that embedded pragmatic effects can be seen as continuous with ordinary, utterance-level, conversational implicature. I will further suggest, though, that embedded pragmatic effects do force on us a particular conception of semantics. Specifically, I will (...) argue that an adequate account of the data requires a semantic framework that posits structured contents. (shrink)

Integrative structure modeling is a method for using information from multiple sources to compute structural models of biomolecular systems. It proceeds via four steps: (i) defining the model representation, which determines the variables whose values will be computed; (ii) constructing a function for scoring alternative models according to how well they accommodate input information; (iii) searching a space of candidate models for acceptable models; and (iv) analyzing acceptable models to evaluate their fit with input information. These steps are iterated until (...) a model adequate for addressing biological questions is found. In this paper, we draw lessons from integrative modeling about effective integration and about modeling. We describe what it means to integrate information from multiple sources: Integration amounts to distributing information among the four steps of integrative modeling. Theory and data alike can be sources of information; this process thus generates models of information, rather than models of theory or models of data. We then propose heuristics for distributing information and designing multiple iterations of modeling. Effective iteration requires prioritizing the most reliable information and minimizing the time required to obtain an adequate model. Rather than being constructed from theory and assessed using data, models are constructed from any available information and assessed in a coherentist manner. (shrink)

Many questions about wellbeing involve metaphysical dependence. Does wellbeing depend on minds? Is wellbeing determined by distinct sorts of things? Is it determined differently for different subjects? However, we should distinguish two axes of dependence. First, there are the grounds that generate value. Second, there are the connections between the grounds and value which make it so that those grounds generate that value. Given these distinct axes of dependence, there are distinct dimensions to questions about the dependence of wellbeing. In (...) this paper, I offer a view of wellbeing that gives different answers with respect to these different dimensions. The view is subjectivist about connections but objectivist about grounds. Pluralist about grounds but monist about connections. Invariabilist about connections but variabilist about grounds. Thus, the view offers a simple account that captures the complexity of wellbeing.

I present here a personal perspective on more than three decades of research into the structural biology of the insulin–receptor interaction. The solution of the three‐dimensional structure of insulin in 1969 provided a detailed understanding of the insulin surfaces involved in self‐assembly. In subsequent years, hundreds of insulin analogues were prepared by insulin chemists and molecular biologists, with the goal of relating the structure to the biological function of the molecule. The design of methods for direct receptor‐binding studies in the (...) 1970s, and the cloning of the receptor in the mid 1980s, provided the required tools for detailed structure–function studies. In the absence of a full three‐dimensional structure of the insulin–receptor complex, I attempt to assemble the existing pieces of the puzzle generated by our and other laboratories, in order to generate a plausible mechanistic model of the insulin–receptor interaction that explains its kinetics and negative cooperativity.

Ever since Thomas Kuhn's influential The Structure of Scientific Revolutions (1962), textbooks have suffered a bad reputation. They have been accused of distorting—at times purportedly—history and of feeding students with an unacceptably simplified and optimistic view of science. This attitude started to change only in recent times. With the increase of attention paid not only to how theories are conceived, but also how they are practiced, disseminated, and appropriated, historians have rehabilitated textbooks as a legitimate site of knowledge production. In (...) this paper, I adopt textbooks as an instrument to unfold multiple facets of the culture that allowed quantum physics to flourish between 1900 and the early 1930s. I organize the article around two stories about two major textbooks, i.e., Sommerfeld′s Atombau und Spektrallinien and Dirac′s Principles of Quantum Mechanics. I explore the complex pedagogical cultures underlying these two masterpieces and how they intersect local agendas. (shrink)

Recent work has established a framework for explaining the origin of cognitive novelties—qualitatively distinct cognitive traits—in human beings. This niche construction approach argues that humans engineer epistemic environments in ways that facilitate the ontogenetic and phylogenetic development of such novelties. I here argue that attention to the organized relations between content-carrying informational vehicles, or informational form, is key to a valuable explanatory strategy within this project, what I call structural-causal explanations. Drawing on recent work from Cecilia Heyes, and developing a (...) case study around a novel mathematical capacity, I demonstrate how structural-causal explanations can contribute to the niche construction approach by underwriting the application of explanatory tools and generating new empirical targets.

Recently, I have been arguing for a global constitutional convention focused on protecting future generations. This deliberative body would be akin to the American constitutional convention of 1787, which gave rise to the present structure of government in the United States. It would confront the “governance gap” that currently exists surrounding concern for future generations. In particular, contemporary institutions tend to crowd out intergenerational concern, and thereby facilitate a “tyranny of the contemporary.” They not only fail to address a basic (...) standing threat to humanity and other species, but help that threat become manifest. Climate change is a prime example. In this paper, I sketch out a natural argumentative path toward the global constitutional convention and argue that is difficult to resist. I also insist that we should be evenhanded in the way we treat the proposal. Those who put their faith in alternatives must also confront standard complaints about naivety, urgency, threats to democratic values, and the like. Moreover, the global constitutional convention has the advantage of addressing the problem we face head on. (shrink)
