New technologies have the potential to severely “challenge” or “disrupt” not only our established social practices but our most fundamental concepts and distinctions like person versus object, nature versus artificial or being dead versus being alive. But does this disruption also change these concepts? Or does it merely change our operationalizations and applications of the same concepts? In this paper, I argue that instead of focusing on individual conceptual change, philosophers of socially disruptive technologies (SDTs) should think about conceptual change (...) as a change in a network of interrelated concepts. What really generates a potential social disruption are changes of inferential relations between concepts – whether or not this entails a change of the respective individual concepts. Philosophers of socially disruptive technologies are therefore in the privileged position of being able to avoid commitments regarding the individuation of individual concepts. -/- . (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.

The problematic issues connected to post-truth communication emerged in all their social relevance after the victory of Brexit and Donald Trump in 2016. Fake news, echo chambers, filter bubbles, and a crisis of experts are some of the phenomena of this epoch of digital revolution that everyone is forced to deal with on daily basis. Public media echoed the plea for a return to a connection between reality, truth, and communication that has been advocated for by philosophy and communication studies (...) since the beginning of the century. However, the strategy for effecting this return is not clear. The paper presents two of the most common strategies employed by practitioners of communication in the newsrooms: reliance on a new form of positivism and the necessity of inculcating critical media literacy into the general population. Concluding that both proposals are inadequate, the paper proposes a rich, relational realism stemming from Peirce’s semiotic and metaphysical studies. (shrink)

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)

This paper replies to the comments made in Acta Analytica by Peter Baumann, Kelly Becker, Marian David, Nenad Miščević, Wes Siscoe, and Danilo Šuster on my Knowing and Checking: An Epistemological Investigation (Routledge 2019), hereinafter abbreviated as KC. These papers resulted from a workshop organized by the department of philosophy of the University of Maribor. I am very thankful to the organizers of the workshop and to the authors for their comments.

I identify two kinds of failure in joint action. First, we can fail to ‘do our part’, that is, fail to contribute to fulfilling the joint intention. Second, we can fail to respect our collaborators. Recognizing the distinct natures of both normative relations helps us overcome a key challenge to a reductionist theory of collective intentionality posed by Margaret Gilbert. According to this objection, we have obligations towards others even in immoral joint actions – a claim that was recently supported (...) experimentally. Except for a handful of experimental papers, work on the normativity in joint intention has stagnated. I hope the distinction breathes fresh air into the theoretical and empirical debate. (shrink)

The feeling of shame discussed by Socrates differs from the one considered in the classic distinction between shame culture and guilt culture [Dodds 1951; Williams 1993]. Dodds refers to 9th-century Homeric society and focuses on αἴδομαι understood as fear towards public opinion. What Socrates talks about, instead, is aischýne (αἰσχύνη), such as the feeling of shame Alcibiades only has towards Socrates, for which not public opinion but one’s own conscience matters (Smp. 216 b-c). Socrates’ standpoint does not coincide at all (...) with the dominant dòxa, nor does it intend to undermine Alcibiades’ moral autonomy by inducing his sense of shame. On the contrary, it performs a cathartic function that is essential for the care of the soul, which is an indispensable premise for Alcibiades to learn to govern himself. (shrink)

In this paper, I argue that the concept of ecstasy (Ekstase), which Schelling elaborates on starting from the Erlanger Vorträge, is his response to Hegel’s famous «shot from a pistol». With this concept, Schelling overcomes the notion of «intellectual intuition», which was at the core of Hegel’s critics, and can now conceive the preeminence of existence (in the sense of Freudigkeit der Existenz) over Being (Sein). Thus, the theory of ecstasy puts Schelling beyond German Idealism and, under some aspects, allows (...) for a post-Heideggerian reading of his philosophy. (shrink)

Many psychologists currently assume that there is a psychologically real distinction to be made between concepts that are abstract and concepts that are concrete. It is for example largely agreed that concepts and words are more easily processed if they are concrete. Moreover, it is assumed that this is because these words and concepts are concrete. It is thought that interesting generalizations can be made about certain concepts because they are concrete. I argue that we have surprisingly little reason to (...) believe that the abstract‐concrete distinction is psychologically real. (shrink)

Although the philosophical ideas of the English philosopher Robin George Collingwood on history and art have often been compared with those of the German philosopher Wilhelm Dilthey, an in-depth comparison between their concepts of metaphysics was never made. Therefore, the focus in this article is on both authors’ concepts of metaphysics. It is shown that, despite the undeniable affinity, their views of the status of metaphysics differ substantially. Both Dilthey and Collingwood focus on an inherent antinomy in the project of (...) metaphysics. On the one hand, there is the inescapable relativity of all time-bound ways of thinking and their results; on the other, there is the metaphysical search for objective and generally accepted knowledge of reality as a whole. For Dilthey, the awareness of its historical character reveals the impossibility for metaphysics to provide a foundation for natural and human sciences alike. Collingwood’s aim, by contrast, is to safeguard the possibility of metaphysics as a historical science to supply an enduring foundation of natural and human sciences. To clarify this radical difference with regard to the role of metaphysics, I make three steps. First, I situate Dilthey’s critique of metaphysics within the context of his work in order to present his ‘solution’ of the metaphysical antinomy. Second, I focus on the role of Collingwood’s reform of metaphysics and his ‘solution’ of the metaphysical antinomy. Finally, I relate the different status of their views of metaphysics to their divergent interpretations of human finitude. (shrink)

In 1731, Filippo Argelati printed for the first time the complete works of the Modenese historian Carlo Sigonio. Intended originally as an edition in five volumes, the collection was augmented by a sixth volume after the discovery in Rome of previously unknown manuscripts of Sigonio. Among the new papers were four sets of ecclesiastical censures which had been secretly directed in the 1580s against four of Sigonio’s works, and, with them, Sigonio’s responses to the papal authorities. According to Argelati, the (...) censures and Sigonio’s responses were found in two manuscripts, one from the vatican Library and the other from the city of Bologna. Until now, the veracity of Argelati’s account has never been questioned. Yet, while there is no doubt about the authenticity of the censures, which are attested also by eight other sixteenth-century manuscripts, Sigonio’s replies do raise doubts, as three-quarters of them are known only from Argelati’s edition of his works. The present article investigates the sources used by the author of the replies. This new evidence clearly proves that, in fact, the replies were written centuries after Sigonio’s death, probably in the same period as Argelati’s edition. In turn, this supports the hypothesis that Sigonio’s works were employed as an instrument to oppose the Roman Church’s political claims, in the jurisdictional debate between the papacy and the empire in the early eighteenth century.

In the chapter of this 2008 book, I show that Scheler innovatively reinterprets the Platonic concept of eros and places it at the basis of his philosophical anthropology.

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?

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)

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)

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.

_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.

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)
