In this collection of informal reminiscences, first published in 1975, Max Born has written an extraordinarily vivid account of his life and work, originally intended for his family. Ranging from his time at the University of Göttingen, where Born had his first real motivation for a professional career in science, to the period in Berlin as professor extraordinary, when he and his wife became close friends of Einstein, these anecdotes and memories chart the "heroic age of physics" from the perspective (...) of one of its leading characters. In 1954 Born was awarded the Nobel Prize in physics for his fundamental contributions to the great discovery of that cadre of superlative scientific minds – quantum theory. But his scientific research provides only one strand of this story. Born's varied interests outside science led to many interesting experiences – some of historical importance insofar as they offer a glimpse into German society before and between the wars. (shrink)

Background: Positive effects of acute exercise on cognitive performances in general inspired research that investigated the effects of acute exercise on specific cognitive subdomains. Many existing studies examined beneficial effects of acute exercise on subsequent set shifting performance in healthy adults. Set shifting, a subdomain of executive function, is the ability to switch between different cognitive sets. The results of existing studies are inconsistent. Therefore, a meta-analysis was conducted that pooled available effect sizes. Additionally, moderator analyses were carried out to (...) identify covariates that determine the magnitude of exercise-induced set shifting benefits.Methods: Medline, PsycINFO, and SPORTDiscus were searched for eligible studies. Hedges' g corrected standardized mean difference values were used for analyses. Random-effects weights were applied to pool effects. Potential moderation of the effect of acute exercise on subsequent set shifting performance by exercise intensity, type of exercise, participants' age, and type of control group were examined.Results: Twenty-two studies were included into analysis. All aggregated effect sizes ranged from small to moderate. Overall, a small significant beneficial effect was revealed. Heterogeneity of included effect sizes was moderate and significant. Moderator analyses revealed a larger average effect in older adults than for studies examining younger adults. Light exercise led to larger effects than moderate or vigorous exercise. Studies testing acute exercise against active control groups showed a noticeably smaller average effect than studies that used passive or cognitive engaging control groups. Interestingly, application of resistance or aerobic exercise led to no different average effect sizes. However, none of the tested covariates reached statistical significance.Conclusion: Acute exercise improves subsequent set shifting performance. However, effect sizes are small, making the relevance for everyday life questionable. The results indicate that older adults benefit more from acute exercise than younger adults do. Light intensity exercise seems most effective while the type of exercise does not seem to influence the magnitude of effects. Research designs with active control groups show the smallest average effect, raising concerns about placebo effects.PROSPERO registration number: CRD42019138799. (shrink)

While the conceptual depths of Aldo Leopold’s land ethic have been limned by environmental ethicists, the relevance of his philosophy to ecologicalrestoration—an applied environmental science—is less well known. I interpret some of his contributions to ecological restoration by framing his work within an expanded evolutionary frame. I especially emphasize the importance of natural beauty to his thinking. Recontextualized as a manifestation of emergent evolutionary complexity, the beauty of nature is fundamental not only to strong ecological restoration, but to reframing our (...) own self-conceptualizations—that is, the human place in the larger order of nature.

David Hume's Essays, which were written and published at various junctures between 1741 and his death in 1776, offer his most accessible and often most profound statements on a range of subjects including politics, philosophy, aesthetics, and political economy. In Hume's lifetime, the readable and wide-ranging Essays acquired considerable fame throughout Europe and North America, influencing the writings of such diverse figures as James Madison and William Paley, yet they have not been given the same scholarly attention as his more (...) famous philosophical works. This Critical Guide provides a series of in-depth studies of the Essays, as well as an account of the state of scholarship on the work. Thirteen chapters examine the Essays from historical, political and philosophical perspectives, with the aim of restoring the work to its rightful place among Hume's works and in intellectual history more broadly.

"The Notion of the concrete General in Plato and Aristotle – Questioning formal logical Ontologies" - The problem of the concrete general notion is equivalent to enquiring about the unity of the general and the singular. Since Plato, this question - which is commonly referred to as the problem of methexis – is one of the most fundamental problems which philosophy is engaged in. This article pursues two goals: Firstly, it aims to provide a brief systematical account on the origin (...) and the solution of this problem with regards to Plato and Aristotle. In doing so, Plato’s solution of the problem of methexis, in the dialectic of his late period, is contrasted with Aristotle’s concept of substance. In this regard the question arises whether Aristotle’s thinking of the problem of methexis has exceeded his teachers achievements in the field of fundamental philosophy or not. Is Aristotle not ultimately avoiding the dialectic, which is contained in the concept of substance – for reasons of formal logic? This point, secondly, shall question the currently prevailing implicitness of the presupposed autarky of formal logic. For it is the very problem of logical justification of the concept of substance in Aristotle which raises this issue: Can the notion of the concrete general be conceivable at all under the precondition that formal logical axioms are also ontologically relevant?

Hegels Philosophie eröffnet einen tiefen Blick auf das Phänomen von Religion – ein Blick, der dem Feuer der aufklärerischen Kritik standhält. Die Religion vergegenwärtigt den Lebenssinn in seiner Totalität. Welche bleibende Relevanz hat dies? Hegel's philosophy offers a deep insight into the phenomenon of religion—one that withstands the fire of Enlightenment criticism. Religion reveals the meaning of life in its totality. What lasting relevance does this have?

We present a relative consistency proof for second order systemRRC* and for certain important extensions of this system. The proof proceeds as follows: we prove first the equiconsistency of the strongest of such extensions (viz., systemH RRC*+(/CP**)) with second order systemT * . Now, N. Cocchiarella has shown thatT * is relatively consistent to systemT*+Ext; clearly, it follows thatH RRC*+(/CP**) is relatively consistent toT*+E xt. As an immediate consequence, the relative consistency ofRRC* and the other extensions also follows, being all (...) of them subsystems ofH RRC*+(/CP**). (shrink)

In 1925-26, the late Max Born gave two sets of lectures at M.I.T., one on the structure of the atom, the other on the lattice theory of rigid bodies. Problems of Atomic Dynamics contains the text of both sets.What gives this volume its remarkable interest is just those dates: 1925-26. This must have been, by all accounts, the headiest period in twentieth-century physics, and Max Born was one of the leaders of the ferment. As Norbert Wiener remembers, "When Professor Born (...) came to the United States [for these lectures in 1925] he was enormously excited about the new basis Heisenberg had just given for the quantum theory of the atom."These lectures represent perhaps the most vivid written record of the transition between the "old" quantum theory of Bohr, and the "new" theory. "At the time I began this course of lectures," Born writes, "Heisenberg's first paper on the new quantum theory had just appeared. Here his masterly treatment gave the quantum theory an entirely new turn. The paper of Jordan and myself, in which we recognized the matrix calculus as the proper formulation of Heisenberg's ideas, was in press, and the manuscript of a third paper by the three of us was almost completed."Even as the lecture series progressed, Born became familiar with new results, which he introduced into his presentation: Pauli's fourth quantum number, Dirac's formalism, his own work on a general operational calculus. And yet, in spite of the conditions of revolutionary changes in physics that year -- in which established ancien regime principles were collapsing almost monthly -- the theory is developed with a cool elegance and with a formal completeness which may be regarded as a "limiting case" of its current state. These lectures represent the foundations of quantum theory, and they have withstood the tests of time -- the tests of more than forty years of experimental evidence. (shrink)

Intersectionality and Relational Psychoanalysis: New Perspectives on Race, Gender, and Sexuality examines the links between race, gender, and sexuality through the dual perspectives of relational psychoanalysis and the theory of intersectionality. Combining intersectional theory with relational psychoanalytic thought, the authors introduce a number of thought-provoking clinical vignettes to suggest how adopting an intersectional approach can help us navigate the space between pathology and difference in psychotherapy.

The original version of the Principle of Verifiabüity (PV), formulated as "The meaning of a proposition is the method of its verification" (Schlick, quoting Wittgenstein), can be criticised as ungrammatical. Schlick's claim that it was a "truism" reflecting commonsense and scientific practice is refuted by PV's paradoxical consequences. Its users faüed to distinguish between operational and situational readings, the latter of which invokes a mythology of comparison with "facts". Wittgenstein rightly described PV as a "rule of thumb" of limited usefulness.
