I review at a non-technical level the use of the gauge-string duality to study aspects of heavy ion collisions, with special emphasis on the trailing string calculation of heavy quark energy loss. I include some brief speculations on how variants of the trailing string construction could provide a toy model of black hole formation and evaporation. This essay is an invited contribution to “Forty Years of String Theory” and is aimed at philosophers and historians of science as well as physicists.

Constructivist biosemiotics foundations imply the first-person basis of cognition. CBF are developed by the biology of cognition, relational biology, enactive approach, ecology of mind, second order cybernetics, genetic epistemology, gestalt, ecological perception and affordances, and active inference by minimization of free energy. CBF reject the idea of an objective independent reality to be represented by information processing in order to be the fittest. CBF assumes that perception is the behavioral configuration of an object and objects are tokens for eigen-behaviors. Cognition (...) takes place in the organism-environment structural coupling during the ontogeny and phylogeny of all biological unities including unicellular organisms. Therefore, if exogenous DNA particles are just tokens for the cell signalling eigen-behaviors, if there is no ‘information’ in the DNA sequence, how can we explain that the same virus or trans- sequence is associated with a similar phenotype? We call this ‘exogenomic problem’. With this basic example, but sufficiently generic to the whole biological world, we agree respectively with Autopoiesis, -system, and Gaia theory: i) ‘Information, code and meaning’ in the DNA sequence belong to the domain of the observer’s description. ii) Genetic ‘information’ is not a program or algorithmic software in DNA sequence. Rather it is a microphysical observable mode of eigen-behaviors in biological unities. iii) The transfer and acquisition of DNA particles is a biospheric phenomenon that maintains its homeorhesis, symbiotic and biosemiotic entailment. Based on the theoretical and experimental results of these theories, it is concluded that genetic ‘information’ is not a genomic sequence, nor any kind of information, but for the cell DNA must embody physical forcing. Genetic characters are the effects and not the cause of phenotype and DNA particles do not ‘use or manipulate’ cellular metabolism. Rather, any cellular configuration change that occurred before or during DNA perturbation is determined on the basis of the cellular standpoint. (shrink)

I assess Anselm’s claim that the debt of sin is "infinite" by examining the thought-experiment used to illustrate it. The claim crashes due to a conflict with Anselm’s implied (and plausible) view of God’s obligations and due to interesting errors in his thought-experiment. Nevertheless, I defend his "Union-of-Obligation-and-Ability (UOA) strategy and his "Provision-of-Satisfaction" mechanism for explaining atonement, which relied functionally on sin’s infinite demerit, by changing them a bit. I also defend Anselm’s UOA and "Disorder-Avoidance" strategies from objections from Duns (...) Scotus. (shrink)

I criticize Richard Swinburne's account of the need for and means of atonement in his "Responsibility and Atonement." I offer objections to his understanding and use of the notion of 'the gift of life' in his account of the need for atonement; and closely related to that, I show that his conclusions about duties to God as a benefactor do not follow from his reasons. Furthermore, when examined closely, these conclusions seem false. In relation to his account of the means (...) of atonement, I argue that the mechanism he provides to explain how Christ's actions benefit sinners does not work. (shrink)

Design patterns are generalized solutions to frequently recurring problems. They were initially developed by architects and computer scientists to create a higher level of abstraction for their designs. Here, we extend these concepts to cell biology to lend a new perspective on the evolved designs of cells' underlying reaction networks. We present a catalog of 21 design patterns divided into three categories: creational patterns describe processes that build the cell, structural patterns describe the layouts of reaction networks, and behavioral patterns (...) describe reaction network function. Applying this pattern language to the E. coli central metabolic reaction network, the yeast pheromone response signaling network, and other examples lends new insights into these systems. (shrink)

There has been increasing interest in developing practical, non-theoretical tools for analyzing ethical problems in public health, biomedicine, and other scientific disciplines so that professionals can make and justify ethical decisions in their own research or practice. Tools for ethical decisionmaking, together with case studies on ethics, are often used in graduate education programs and in continuing professional education. Students can benefit from opportunities to further develop their analytical skills, to recognize ethical issues, and to develop their moral sensitivity. One (...) practical approach for illustrating and facilitating ethical analysis uses cases with contrary facts and circumstances, an approach which complements rather than replaces theoretical approaches to moral reasoning. Cases with contrary facts and circumstances are presented in two or more alternative ways so that the facts, circumstances, or framing of one version runs counter to that of the other version (s). Cases with contrary facts, together with practical steps for identifying and analyzing ethical issues, are likely to be useful tools for illustrating and facilitating ethics analysis and stimulating the moral imagination.

Previous claims that psychology is propaedeutic to the other sciences have been met with enthusiastic indifference. Contributing to this indifference has been the fact that psychology, a young and unproved discipline which habitually borrowed the methods of the older sciences, has too frequently revised its notion as to its own nature and subject-matter. More important, however, has been the faith of the physical sciences in the absolute character of their own basic concepts: in the reality of Absolute Space and Absolute (...) Time and in the universality of deterministic principles, for, as long as physics presumed to deal with entities which are what they are regardless of the nature of man, nothing other than these entities appeared to demand prior consideration. The problem of the nature of the observer in the physical experiment became important to physics only as a consequence of the recent ‘subjective’ revolution. It is this revolution which has revitalized the problem of the propaedeutic science and has accentuated the distinction which we must make between the behavioral phenomenon of individuals creating formal arrays of words or symbols which are without operational meaning and the discriminatory responses, or operations, by which the empirical meaning of such arrays is determined.

Complete collection of Schwarzschild’s essays on the neo-Kantian Jewish philosopher Hermann Cohen. Steven S. Schwarzschild (1924–1989) was arguably the leading expositor of German-Jewish philosopher Hermann Cohen (1842–1918), undertaking a lifelong effort to reintroduce Cohen’s thought into contemporary philosophical discourse. In The Tragedy of Optimism, George Y. Kohler brings together all of Schwarzschild’s work on Cohen for the first time. Schwarzschild’s readings of Cohen are unique and profound; he was conversant with both worlds that shaped Cohen’s thought, neo-Kantian German idealism (...) and Jewish theology. The collection covers a wide range of subjects, from ethics, socialism, the concept of human selfhood, and the mathematics of the infinite to more explicitly Jewish themes. This volume includes two of Schwarzschild’s previously unpublished manuscripts and a scholarly introduction by Kohler. Schwarzschild shows that despite its seeming defeat by events of the twentieth century, Cohen’s optimism about human progress is a rational, indeed necessary, path to peace. George Y. Kohler is Director of the Joseph Carlebach Institute and Senior Lecturer of Jewish Philosophy at Bar Ilan University, Israel. He is the author of Reading Maimonides’ Philosophy in 19th Century Germany: The Guide to Religious Reform. (shrink)

The application of AI in medicine (AIM) is producing health practices more reliable, accurate and efficient than traditional medicine (TM) by assisting partly / totally the medical decision-making, such as the use of deep learning in diagnostic imagery, designing treatment plans or preliminary diagnosis. Yet, most of these AI systems are pure “black-boxes”: the practitioner understands the inputs and outputs of the system but cannot have access to what happens “inside” it and cannot offer an explanation, creating an opaque process (...) that culminates in a “trust gap” in two levels: (a) between patients and the medical experts; (b) between the medical expert and the medical process itself. This creates a “black-box medicine” since the practitioner ought to rely (epistemically) on these AI systems that are more accurate, fast and efficient than any expert or group of human experts but are not transparent (epistemically) and do not offer any kind of explanation. In this paper, we want to introduce some preliminary remarks about the pros and cons of three possible solutions to deal with the “trust gap” in AIM. (shrink)

Semantics: A Reader contains a broad selection of classic articles on semantics and the semantics/pragmatics interface. Comprehensive in the variety and breadth of theoretical frameworks and topics that it covers, it includes articles representative of the major theoretical frameworks within semantics, including: discourse representation theory, dynamic predicate logic, truth theoretic semantics, event semantics, situation semantics, and cognitive semantics. All the major topics in semantics are covered, including lexical semantics and the semantics of quantified noun phrases, adverbs, adjectives, performatives, and interrogatives. (...) Included are classic papers in the field of semantics as well as papers written especially for the volume. The volume comes with an extensive introduction designed not only to provide an overview of the field, but also to explain the technical concepts the beginner will need to tackle before the more demanding articles. Semantics will have appeal as a textbook for upper level and graduate courses and as a reference for scholars of semantics who want the classic articles in their field in one convenient place.

In this paper, we argue that one way to approach what is known in the literature as the “Trust Gap” in Medical AI is to focus on explanations from an Explainable AI (xAI) perspective. Against the current framework on xAI – which does not offer a real solution – we argue for a pragmatist turn, one that focuses on understanding how we provide explanations in Traditional Medicine (TM), composed by human agents only. Following this, explanations have two specific relevant components: (...) they are usually (i) social and (ii) abductive. Explanations, in this sense, ought to provide understanding by answering contrastive _why-questions_: “Why had P happened instead of Q?” (Miller in AI 267:1–38, 2019) (Sect. 1 ). In order to test the relevancy of this concept of explanation in medical xAI, we offer several reasons to argue that abductions are crucial for medical reasoning and provide a crucial tool to deal with trust gaps between human agents (Sect. 2 ). If abductions are relevant in TM, we can test the capability of Artificial Intelligence systems on this merit. Therefore, we provide an analysis of the capacity for social and abductive reasoning of different AI technologies. Accordingly, we posit that Large Language Models (LLMs) and transformer architectures exhibit a noteworthy potential for effective engagement in abductive reasoning. By leveraging the potential abductive capabilities of LLMs and transformers, we anticipate a paradigm shift in the integration of explanations within AI systems. This, in turn, has the potential to enhance the trustworthiness of AI-driven medical decisions, bridging the Trust Gap that has been a prominent challenge in the field of Medical AI (Sect. 3 ). This development holds the potential to not only improve the interpretability of AI-generated medical insights but also to guarantee that trust among practitioners, patients, and stakeholders in the healthcare domain is still present.

The ongoing importance of the philosophic work of Hermann Cohen, founder of “Marburg neo-Kantianism,” is far too little known or appreciated. This is also true of the extension of his systematic work to philosophy of religion, and among Jews his philosophy of Judaism is largely misunderstood.
