The current study investigated attachment representations and complex trauma in a sample of gender dysphoric adults. Although it has been proven that the psychological wellbeing of gender diverse persons is largely mediated by family acceptance and support, research on their relationships with parental figures is scarce. A total of 95 adults took part in the study. The attachment distribution was as follows: 27% secure, 27% insecure and 46% disorganized. Regarding early traumas, 56% experienced four or more traumatic forms. Further, gender (...) dysphoric adults showed significantly higher levels of attachment disorganization and polyvictimisation, relative to controls. Comparisons of subgroups, defined by natal gender, showed that trans women, compared to control males, had more involving and physically and psychologically abusive fathers, and were more often separated from their mothers; trans men, relative to female controls, had more involving mothers and were more frequently separated from and neglected by their fathers. The research has several implications for treatment, clinical health psychology, family support and education. (shrink)

We systematically study the completion of choice problems in the Weihrauch lattice. Choice problems play a pivotal rôle in Weihrauch complexity. For one, they can be used as landmarks that characterize important equivalences classes in the Weihrauch lattice. On the other hand, choice problems also characterize several natural classes of computable problems, such as finite mind change computable problems, non-deterministically computable problems, Las Vegas computable problems and effectively Borel measurable functions. The closure operator of completion generates the concept of total (...) Weihrauch reducibility, which is a variant of Weihrauch reducibility with total realizers. Logically speaking, the completion of a problem is a version of the problem that is independent of its premise. Hence, studying the completion of choice problems allows us to study simultaneously choice problems in the total Weihrauch lattice, as well as the question which choice problems can be made independent of their premises in the usual Weihrauch lattice. The outcome shows that many important choice problems that are related to compact spaces are complete, whereas choice problems for unbounded spaces or closed sets of positive measure are typically not complete.

We prove that the Weihrauch lattice can be transformed into a Brouwer algebra by the consecutive application of two closure operators in the appropriate order: first completion and then parallelization. The closure operator of completion is a new closure operator that we introduce. It transforms any problem into a total problem on the completion of the respective types, where we allow any value outside of the original domain of the problem. This closure operator is of interest by itself, as it (...) generates a total version of Weihrauch reducibility that is defined like the usual version of Weihrauch reducibility, but in terms of total realizers. From a logical perspective completion can be seen as a way to make problems independent of their premises. Alongside with the completion operator and total Weihrauch reducibility we need to study precomplete representations that are required to describe these concepts. In order to show that the parallelized total Weihrauch lattice forms a Brouwer algebra, we introduce a new multiplicative version of an implication. While the parallelized total Weihrauch lattice forms a Brouwer algebra with this implication, the total Weihrauch lattice fails to be a model of intuitionistic linear logic in two different ways. In order to pinpoint the algebraic reasons for this failure, we introduce the concept of a Weihrauch algebra that allows us to formulate the failure in precise and neat terms. Finally, we show that the Medvedev Brouwer algebra can be embedded into our Brouwer algebra, which also implies that the theory of our Brouwer algebra is Jankov logic. (shrink)

In this paper we propose an extension of Defeasible Logic to represent and compute different concepts of defeasible permission. In particular, we discuss some types of explicit permissive norms that work as exceptions to opposite obligations or encode permissive rights. Moreover, we show how strong permissions can be represented both with, and without introducing a new consequence relation for inferring conclusions from explicit permissive norms. Finally, we illustrate how a preference operator applicable to contrary-to-duty obligations can be combined with a (...) new operator representing ordered sequences of strong permissions. The logical system is studied from a computational standpoint and is shown to have linear computational complexity. (shrink)

I discuss the interpretation of spontaneous collapse theories, with particular reference to Bell's suggestion that the stochastic jumps in the evolution of the wave function should be considered as local beables of the theory. I develop this analogy in some detail for the case of non-relativistic GRW-type theories, using a generalisation of Bell's notion of beables to POV measures. In the context of CSL-type theories, this strategy appears to fail, and I discuss instead Ghirardi and co-workers' mass-density interpretation and its (...) relation to Schrödinger's original charge-density interpretation. This discussion is extended to relativistic CSL-type theories. A few remarks on Everett's interpretation conclude the paper. (shrink)

In this paper I generalize the new approach to nonmonotonicreasoning that was presented in [6]. This generalization results in the inconsistency-adaptive logic PRL . I give proof theory, semantics, mention interesting properties,and comment on the reconstruction and amelioration of other nonmonotoniclogics and mechanisms.

The essays collected in this volume explore the fundamental issues of philosophical realism, including metaphysical realism. Do things exist and have properties independently of being objects of thought or perception? epistemological realism: Is it possible to know any part of reality in and of itself? and ontological realism: Are there universals?

In a recently published study combining transcranial magnetic stimulation and electroencephalography (TMS-EEG), an early component of TMS-evoked potentials (TEPs), i.e., M1-P15, was proposed as a measure of transcallosal inhibition between motor cortices. Given that early TEPs are known to be highly variable, further evidence is needed before M1-P15 can be considered a reliable index of effective connectivity. Here, we conceived a new preregistered TMS-EEG study with two aims. The first aim was validating the M1-P15 as a cortical index of transcallosal (...) inhibition by replicating previous findings on its relationship with the ipsilateral silent period (iSP) and with performance in bimanual coordination. The second aim was inducing a task-dependent modulation of transcallosal inhibition. A new sample of 32 healthy right-handed participants underwent behavioral motor tasks and TMS-EEG recording, in which left and right M1 were stimulated both during bimanual tasks and during an iSP paradigm. Hypotheses and methods were preregistered before data collection. Results show a replication of our previous findings on the positive relationship between M1-P15 amplitude and the iSP normalized area. Differently, the relationship between M1-P15 latency and bimanual coordination was not confirmed. Finally, M1-P15 amplitude was modulated by the characteristics of the bimanual task the participants were performing, and not by the contralateral hand activity during the iSP paradigm. In sum, the present results corroborate our previous findings in validating the M1-P15 as a cortical marker of transcallosal inhibition and provide novel evidence of its task-dependent modulation. Importantly, we demonstrate the feasibility of preregistration in the TMS-EEG field to increase methodological rigor and transparency. (shrink)

This essay questions the self-sufficiency of abstract, non-consequentialist, principles as a defence of a libertarian regime. The argument focuses on the difficulties involved in attempts to defend the priority of negative rights if an attractive conception of freedom and an agent-relative view about our reasons to respect rights are to be upheld. The paper closes by suggesting how libertarianism could gain support from various, and perhaps mutually irreducible and even conflicting, considerations in a wide consequentialist system.

The axiomatic bases of Special Relativity Theory (SRT) are thoroughly re-examined from an operational point of view, with particular emphasis on the status of Einstein synchronization in the light of the possibility of arbitrary synchronization procedures in inertial reference frames. Once correctly and explicitly phrased, the principles of SRT allow for a wide range of “theories” that differ from the standard SRT only for the difference in the chosen synchronization procedures, but are wholly equivalent to SRT in predicting empirical facts. (...) This results in the introduction, in the full background of SRT, of a suitable synchronization gauge. A complete hierarchy of synchronization gauges is introduced and elucidated, ranging from the useful Selleri synchronization gauge (which should lead, according to Selleri, to a multiplicity of theories alternative to SRT) to the more general Mansouri–Sexl synchronization gauge and, finally, to the even more general Anderson–Vetharaniam–Stedman’s synchronization gauge. It is showed that all these gauges do not challenge the SRT, as claimed by Selleri, but simply lead to a number of formalisms which leave the geometrical structure of Minkowski spacetime unchanged. Several aspects of fundamental and applied interest related to the conventional aspect of the synchronization choice are discussed, encompassing the issue of the one-way velocity of light in inertial and rotating reference frames, the global positioning system (GPS)’s working, and the recasting of Maxwell equations in generic synchronizations. Finally, it is showed how the gauge freedom introduced in SRT can be exploited in order to give a clear explanation of the Sagnac effect for counter-propagating matter beams. (shrink)

The German phenomenologist Max Scheler, commonly considered one of the most important exponents of value objectivism, does not claim an “absolute” value objectivism, as often asserted. The values are objecttive towards the will of the subject, not towards the creative act of loving. This presupposes a radical new conception of the value. According to Scheler, in fact, the values are no qualities to be attributed to the perceived object but the very first thing grasped on a phenomenon, i.e. the “first (...) messenger” (erste Bote) of the phenomenon: the value is what orients the formation and development of the experience. This paper proposes to deal with the problem of the value objectivism in relation to the self-transcendence and to the self-realization of the person. The value objectivism should be measured by its faculty to orient the act through which a person detaches himself from the proper factual self. The “Good” isn‟t therefore related to an ideal transcendent object, but to the act to transcend the proper self in a creative way. The fundamental thesis is that the personal identity constitutes itself only in a critical distancing from the self. This concrete act of self-transcending cannot be understood merely in the sense of the self-interpretation – of the “strong evaluations” of Charles Taylor – but requires also the presence of the exemplarity of the other.

Guido de Ruggiero (1888-1948) was perhaps the greatest Italian intellectual historian in the twentieth century. He was a fierce champion of liberalism, an ardent opponent of Fascism, an insightful critic and interpreter of his contemporaries, and a formidable philosopher in his own right. Idealism & Experience: The Philosophy of Guido de Ruggiero comprises eight new critical essays, as well as English translations of five of de Ruggiero's most important shorter writings, which chart the development of his thought between (...) 1914 and 1946. Taken together, these essays reveal the range, richness and philosophical sophistication of de Ruggiero's ideas, enabling Anglophone readers to appreciate their enduring relevance in our own troubled times.

The fascinating Journey of the Renaissance Medicine.

_Brill's Companion to Medieval and Early Platonism_ explores the impact exercised by Platonism on philosophy and many other fields of European culture, and the links it established with Christian, Jewish, Byzantine and Arabic traditions of thought during the Middle Ages and the early modern period.

We provide results allowing to state, by the simple inspection of suitable classes of posets , that the corresponding intermediate propositional logics are maximal among the ones which satisfy the disjunction property. Starting from these results, we directly exhibit, without using the axiom of choice, the Kripke frames semantics of 2No maximal intermediate propositional logics with the disjunction property. This improves previous evaluations, giving rise to the same conclusion but made with an essential use of the axiom of choice, of (...) the cardinality of the set of the maximal intermediate propositional logics with the disjunction property.

Among the rules which govern the "language-games" discussed by Wittgenstein there are some which seem to have particular functions which can be more effectively brought to light by considering the logical and pragmatic effects of their breakage. Indeed, if we extend progressively the analysis of possible breakages of such rules from particular language-games to broader and broader areas of language, we arrive at a point where (as happened in the Tractatus) it seems possible to draw a limit between what, in (...) general terms, is endowed with sense, and what is devoid of it. This possibility, offered by a "rule-breaking" approach, also opens a promising perspective from which to look afresh at some classical problems connected with skepticism. (shrink)

After a brief reconstruction of the principle of precaution’s juridical rising, I will discuss in short the question of the juridical nature of the same principle and then examine some of its extra-juridical implications, showing how the intrinsic logic of the principle of precaution implies a strict connection with the needs and proper forms of a conception of democracy as participative.

Revisionen moralischer Überzeugungen erfordern nach allgemeiner Auffassung einen festen Bezugspunkt: einen stabilen moralischen Charakter der umdenkenden Personen. Andernfalls können diesen ihre Überzeugungen, Entscheidungen und Handlungen nicht zugerechnet werden. So lehren metaethische Generalisten einerseits und Partikularisten andererseits, für Charakterstabilität seien fixe Moralprinzipien bzw. eine fixe moralische Feinfühligkeit konstitutiv. Beiden Positionen zufolge zielen Revisionen auf moralische Richtigkeit im Sinne synchroner Kohärenz niedrigstufiger moralischer Überzeugungen . Der kritische Befund: Das statische Vermögen, in moralischen Dingen immer richtig zu liegen, bildet keine einer besonderen Zurechnung (...) fähigen moralischen Charaktere aus; das dynamische Vermögen, sich selbst auf angemessene Weise korrigieren zu können, dagegen wohl. Darum argumentiert der Beitrag erstens dafür, Charakterstabilität als diachrone Kohärenz unserer moralischen Überzeugungen aufzufassen. Zweitens wird für eine Sicht plädiert, nach der iterative Revisionen moralischer Überzeugungen nicht nur Moralprinzipien gemäß vorgenommen werden, sondern diese auch affizieren und deren maßvolle Veränderung nach sich ziehen können. Zuletzt wird diskutiert, nach welchen Strategien sich Revisionen dieser Art vollziehen sollten. (shrink)

Gottesbeweise gehören zu den großen Themen der abendländischen Philosophie. Im 20. Jahrhundert sind sie mit Hilfe der modernen Logik neu formuliert worden und auch in der analytischen Philosophie werden Gottesbeweise seit Jahrzehnten kontrovers diskutiert. Offenkundig ist die Frage nach der Existenz Gottes im nachmetaphysischen Zeitalter aktueller denn je. Der Band versammelt die großen Gottesbeweise des Mittelalters und der Neuzeit ebenso wie die klassischen Einwände von Hume und Kant. Die sprachanalytische Debatte wird ausführlich dokumentiert und ein eigener Teil ist Kurt Gödel (...) gewidmet, dessen ontologischer Beweis bis heute nicht stichhaltig widerlegt worden ist. Umfassende einleitende Essays führen in die Problematik der Gottesbeweise ein und bieten gut verständliche Rekonstruktionen der jeweiligen Beweisversuche. (shrink)

Regarding the influence of Francois Rabelais on the Giordano Bruno’s works, up to now the criticism have only taken into consideration the lexical and thematic analogies. This article individualizes, in a passage of the "Oratio Valedictoria", a literal quotation from the Gargantua et Pantagruel , showing that Rabelais was adirect source of inspiration for Bruno. The protagonist of the passage is the pythagorean Apollonius of Tyana, a character well known from the Nolan, who mentioned him in many occasions. He represents (...) theideal medium with the oriental wisdom, that had so much influence on the thought of Bruno. Besides, heembodies the model of the "natural magician" in which the philosopher repeatedly identified himself, both inhis works and life. (shrink)

As Jasper Reid argues in his book, there are plenty of reasons for taking More’s philosophy seriously, both as an example of early modern metaphysics and a speculative effort in its own terms. More’s metaphysics was experimental, fictional, and theological at once, for it deliberately and passionately engages with the study of nature, stories of preternatural apparitions and the mysteries of revealed religion. More’s philosophical inquiry feeds on experiments, stories, and visions, and these become an organic part of his metaphysical (...) equipment. This, of course, was a hazardous and edgy undertaking, which no doubt contributed to the bad... (shrink)
