Recording and manipulating neuronal ensemble activity is a key requirement in advanced neuromodulatory and behavior studies. Devices capable of both recording and manipulating neuronal activity brain-computer interfaces should ideally operate un-tethered and allow chronic longitudinal manipulations in the freely moving animal. In this study, we designed a new intracortical BCI feasible of telemetric recording and stimulating local gray and white matter of visual neural circuit after irradiation exposure. To increase the translational reliance, we put forward a Göttingen minipig model. The (...) animal was stereotactically irradiated at the level of the visual cortex upon defining the target by a fused cerebral MRI and CT scan. A fully implantable neural telemetry system consisting of a 64 channel intracortical multielectrode array, a telemetry capsule, and an inductive rechargeable battery was then implanted into the visual cortex to record and manipulate local field potentials, and multi-unit activity. We achieved a 3-month stability of the functionality of the un-tethered BCI in terms of telemetric radio-communication, inductive battery charging, and device biocompatibility for 3 months. Finally, we could reliably record the local signature of sub- and suprathreshold neuronal activity in the visual cortex with high bandwidth without complications. The ability to wireless induction charging combined with the entirely implantable design, the rather high recording bandwidth, and the ability to record and stimulate simultaneously put forward a wireless BCI capable of long-term un-tethered real-time communication for causal preclinical circuit-based closed-loop interventions.

The counterfactual comparative account of harm faces problems in cases that involve overdetermination and preemption. An influential strategy for dealing with these problems, drawing on a suggestion made by Derek Parfit, is to appeal to _plural harm_—several events _together_ harming someone. We argue that the most well-known version of this strategy, due to Neil Feit, as well as Magnus Jedenheim Edling’s more recent version, is fatally flawed. We also present some general reasons for doubting that the overdetermination and preemption problems (...) for the counterfactual comparative account can be satisfactorily solved by appealing to plural harm.

In this paper, we present a new semantic framework designed to capture a distinctly cognitive or epistemic notion of meaning akin to Fregean senses. Traditional Carnapian intensions are too coarse-grained for this purpose: they fail to draw semantic distinctions between sentences that, from a Fregean perspective, differ in meaning. This has led some philosophers to introduce more fine-grained hyperintensions that allow us to draw semantic distinctions among co-intensional sentences. But the hyperintensional strategy has a flip-side: it risks drawing semantic distinctions (...) between sentences that, from a Fregean perspective, do not differ in meaning. This is what we call the ‘new problem’ of hyperintensionality to distinguish it from the ‘old problem’ that faced the intensional theory. We show that our semantic framework offers a joint solution to both these problems by virtue of satisfying a version of Frege’s so-called ‘equipollence principle’ for sense individuation. Frege’s principle, we argue, not only captures the semantic intuitions that give rise to the old and the new problem of hyperintensionality, but also points the way to an independently motivated solution to both problems.

The stakes associated with an algorithmic decision are often said to play a role in determining whether the decision engenders a right to an explanation. More specifically, “high stakes” decisions are often said to engender such a right to explanation whereas “low stakes” or “non-high” stakes decisions do not. While the overall gist of these ideas is clear enough, the details are lacking. In this paper, we aim to provide these details through a detailed investigation of what we will call (...) the “Simple Stakes Thesis”. The Simple Stakes Thesis, as it will turn out, is too simple. For even if the stakes associated with a specific one-off decision are low—and hence does not engender a right to an explanation—such decisions may nevertheless form part of a high stakes pattern or aggregate of decisions. In such cases, we argue, even a low stakes decision may engender a right to explanation. Not only does this show that the right to explanation is more demanding than so far recognized. It also shows that the stakes thesis is significantly harder to apply in practice. (shrink)

According to the “deprivation approach,” a person’s death is bad for her to the extent that it deprives her of goods. This approach faces the Lucretian problem that prenatal non-existence deprives us of goods just as much as death does, but does not seem bad at all. The two most prominent responses to this challenge—one of which is provided by Frederik Kaufman (inspired by Thomas Nagel) and the other by Anthony Brueckner and John Martin Fischer—claim that prenatal non-existence is relevantly (...) different from death. This paper criticizes these responses. (shrink)

In this paper, we give a new argument for the existence of moral luck. The argument is based on a manipulation case in which two agents both lack second-order control over their actions, but one of them has first-order control. Our argument is, we argue, in several respects stronger than standard arguments for moral luck. Five possible objections to the argument are considered, and its general significance for the debate on moral luck is briefly discussed.

We have argued that the counterfactual comparative account of harm and benefit (CCA) violates the plausible adequacy condition that an act that would harm an agent cannot leave her much better off than an alternative act that would benefit her. In a recent paper in this journal, however, Neil Feit objects that our argument presupposes questionable counterfactual backtracking. He also argues that CCA proponents can justifiably reject the condition by invoking so-called plural harm and benefit. In this reply, we argue (...) that Feit’s lines of criticism are both unsuccessful. (shrink)

In this article I discuss the question of whether a person’s existence can be better (or worse) for him than his non-existence. Recently, Nils Holtug and Melinda A. Roberts have defended an affirmative answer. These defenses, I shall argue, do not succeed. In different ways, Holtug and Roberts have got the metaphysics and axiology wrong. However, I also argue that a person’s existence can after all be better (or worse) for him than his non-existence, though for reasons other than those (...) provided by Holtug and Roberts. (shrink)

In this paper, we put forward two novel arguments against the counterfactual comparative account (CCA) of harm and benefit. In both arguments, the central theme is that CCA conflicts with plausible judgements about benefit and prudence.

In a recent article, I criticized Anthony L. Brueckner and John Martin Fischer’s influential argument—appealing to the rationality of our asymmetric attitudes towards past and future pleasures—against the Lucretian claim that death and prenatal non-existence are relevantly similar. Brueckner and Fischer have replied, however, that my critique involves an unjustified shift in temporal perspectives. In this paper, I respond to this charge and also argue that even if it were correct, it would fail to defend Brueckner and Fischer’s proposal against (...) my critique. (shrink)

This paper concerns the double standard debate in the ethics of AI literature. This debate essentially revolves around the question of whether we should subject AI systems to different normative standards than humans. So far, the debate has centered around the desideratum of transparency. That is, the debate has focused on whether AI systems must be more transparent than humans in their decision-making processes in order for it to be morally permissible to use such systems. Some have argued that the (...) same standards of transparency should be applied across the board, for AI systems and humans alike. Others have argued that we should hold AI systems to higher standards than humans in terms of transparency. In this paper, we first point out that there are structurally similar double standard debates to be had about other desiderata besides transparency, such as predictive accuracy. Second, we argue that when we focus on predictive accuracy, there are at least two reasons for holding AI systems to a lower standard than humans. (shrink)

Eristic has been studied more and more intensively in recent years in philosophy, law, communication theory, logic, proof theory, and A.I. Nevertheless, the modern origins of eristic, which almost all current researchers see in the philosopher Arthur Schopenhauer, are considered to be a theory of the illegitimate use of logical and rhetorical devices. Thus, eristic seems to violate the norms of discourse ethics. In this paper, I argue that this interpretation of eristic is based on prejudices that contradict the original (...) intention of modern eristic. Eristic is not an art of being right or winning an argument, but an art of protecting oneself from the one who deliberately violates norms of discourse ethics to gain argumentative acceptance. For this reason, eristic must be seen as a discipline of Enlightenment philosophy and a correlate of discourse ethics. Especially in the age of alternative facts and post-factual politics, this makes eristic a valuable discipline. (shrink)

Derek Parfit famously defends a number of surprising views about "fission." One is that, in such a scenario, it is indeterminate whether I have survived or not. Another is that the fission case shows that it does not matter, in itself, whether I survive or not. Most critics of the first view contend that fission makes me cease to exist. Most opponents of the second view contend that fission does not preserve everything that matters in ordinary survival. In this paper (...) I shall provide a critique that does not rely on either of these contentions. There are other, interrelated reasons to reject Parfit's defense of the two theses. In particular, the availability of the following view creates trouble for Parfit: I determinately survive fission, but it is indeterminate which fission product I am. (shrink)

One increasingly popular approach to personal identity is called ‘animalism.’ Unfortunately, it is unclear just what the doctrine says. In this paper, I criticise several different ways of stating animalism, and put forward one formulation that I find more promising.

Logicians have often suggested that the use of Euler-type diagrams has influenced the idea of the quantification of the predicate. This is mainly due to the fact that Euler-type diagrams display more information than is required in traditional syllogistics. The paper supports this argument and extends it by a further step: Euler-type diagrams not only illustrate the quantification of the predicate, but also solve problems of traditional proof theory, which prevented an overall quantification of the predicate. Thus, Euler-type diagrams can (...) be called the natural basis of syllogistic reasoning and can even go beyond. In the paper, these arguments are presented in connection with the book Nucleus Logicae Weisaniae by Johann Christian Lange from 1712. (shrink)

The epistemic arrow of time is the fact that our knowledge of the past seems to be both of a different kind and more detailed than our knowledge of the future. Just like with the other arrows of time, it has often been speculated that the epistemic arrow arises due to the second law of thermodynamics. In this paper, we investigate the epistemic arrow of time using a fully formal framework. We begin by defining a memory system as any physical (...) system whose present state can provide information about the state of the external world at some time other than the present. We then identify two types of memory systems in our universe, along with an important special case of the first type, which we distinguish as a third type of memory system. We show that two of these types of memory systems are time-symmetric, able to provide knowledge about both the past and the future. However, the third type of memory systems exploits the second law of thermodynamics, at least in all of its instances in our universe that we are aware of. The result is that in our universe, this type of memory system only ever provides information about the past. We also argue that human memory is of this third type, completing the argument. We end by scrutinizing the basis of the second law itself. This uncovers a previously unappreciated formal problem for common arguments that try to derive the second law from the “Past Hypothesis”, i.e., from the claim that the very early universe was in a state of extremely low entropy. Our analysis is indebted to prior work by one of us but expands and improves upon this work in several respects. (shrink)

This paper argues in favor of a hybrid conception of identity. A common conception of identity in datafied society is a split between a digital self and a real self, which has resulted in concepts such as the data double, algorithmic identity, and data shadows. These data-identity metaphors have played a significant role in the conception of informational privacy as control over information—the control of or restricted access to your digital identity. Through analyses of various data-identity metaphors as well as (...) philosophical accounts of identity, we argue in favor of a hybrid conception of identity that emphasizes the relations between the ‘real’ and the ‘digital’. A hybrid conception of identity—where the digital is an aspect on par with social relations, self-understanding, and values—ultimately calls for an understanding of privacy as the right to influence one’s own identity.

In a recent article in this journal, Eli Pitcovski puts forward a novel, explanation-based account of harm. We seek to show that Pitcovski’s account, and his arguments in favor of it, can be substantially improved. However, we also argue that, even thus improved, the account faces a dilemma. The dilemma concerns the question of what it takes for an event, E, to explain why a state, P, does not obtain. Does this require that P would have obtained if E had (...) not occurred? Pitcovski’s theory faces problems no matter how one answers that question. (shrink)

Logicians commonly speak in a relatively undifferentiated way about pre-euler diagrams. The thesis of this paper, however, is that there were three periods in the early modern era in which euler-type diagrams (line diagrams as well as circle diagrams) were expansively used. Expansive periods are characterized by continuity, and regressive periods by discontinuity: While on the one hand an ongoing awareness of the use of euler-type diagrams occurred within an expansive period, after a subsequent phase of regression the entire knowledge (...) about the systematic application and the history of euler-type diagrams was lost. I will argue that the first expansive period lasted from Vives (1531) to Alsted (1614). The second period began around 1660 with Weigel and ended in 1712 with lange. The third period of expansion started around 1760 with the works of Ploucquet, euler and lambert. Finally, it is shown that euler-type diagrams became popular in the debate about intuition which took place in the 1790s between leibnizians and Kantians. The article is thus limited to the historical periodization between 1530 and 1800. (shrink)

It is little known that Schopenhauer (1788–1860) made thorough use of Euler diagrams in his works. One specific diagram depicts a high number of concepts in relation to Good and Evil. It is, hence, uncharacteristic as logicians of that time seldom used diagrams for more than three terms (the number demanded by syllogisms). The objective of this paper is to make sense of this diagram by explaining its function and inquiring whether it could be viewed as an early serious attempt (...) to construct complex diagrams.

From the sumptuous lakeshore to the inner city, these images capture the light, color, and mood of our public spaces throughout the changing seasons. Frederick Law Olmsted's and Jens Jensen's vision of a 'garden in a city' is reflected within the pages of this book. The images at once subtly incorporate and contrast the natural landscape within the urban landscape. The Prairie-style architecture that is found in many of Chicago's parks is both a reflection of the natural prairie (...) and a reminder of the concrete urban landscape within which the parks are located. These full-color photographs of Chicago's well-known and lesser-visited parks make a perfect gift for those who enjoy outdoor spaces or gardens, or for those who fondly remember the parks of their Chicago youth. The totality of these images is an eloquent visual portrait of the origins of our bold and proud city from the vast wilderness of the mid-western prairie. Frank Dina has brought about an impressive re-discovery and re-affirmation of these islands of peace, beauty, and tranquillity amidst the bustle and dynamism that is Chicago. (shrink)

Taboo terms offer a playground for linguistic creativity in language after language, and sign languages form no exception. The present paper offers the first investigation of taboo terms in sign languages from a cognitive linguistic perspective. We analyze the linguistic mechanisms that introduce offense, focusing on the combined effects of cognitive metonymy and iconicity. Using the Think Aloud Protocol, we elicited offensive or crass signs and dysphemisms from nine signers. We find that German Sign Language uses a variety of linguistic (...) means to introduce and enhance offense, many of which rely on iconic properties of the taboo sign. In conjunction with cross-linguistically common metonymic word-formation strategies, the degree of visual explicitness of a sign increases its potential to offend. Semantically similar taboo signs based on the same metonymic anchor but differing in their degree of iconicity also differ in offensiveness. This allows for creating dysphemisms and euphemisms via phonological changes to a sign. We further show that embodiment creates modality-enhanced ‘vicarious embarrassment’ in the viewer that results in the respective signs being judged obscene or offensive. Further, lexical blending and non-manual enhancement play a role in the creation of dysphemisms in DGS. Lastly, we propose that iconicity as a cognitive structuring principle of linguistic expressions constrains the possible semantic extensions of iconic taboo terms. (shrink)

From the mid-1600s to the beginning of the eighteenth century, there were two main circles of German scholars which focused extensively on diagrammatic reasoning and representation in logic. The first circle was formed around Erhard Weigel in Jena and consists primarily of Johann Christoph Sturm and Gottfried Wilhelm Leibniz; the second circle developed around Christian Weise in Zittau, with the support of his students, particularly Samuel Grosser and Johann Christian Lange. Each of these scholars developed an original form of using (...) geometric diagrams in logic. In this paper, I will trace the historical notes of John Venn and other modern logicians back to the original works published in the Weigel and Weise circles and describe the development of using geometric figures for logical reasoning and representation in that period of time.

Contemporary conversations about religion and culture are framed by two reductive definitions of secularity. In one, multiple faiths and nonfaiths coexist free from a dominant belief in God. In the other, we deny the sacred altogether and exclude religion from rational thought and behavior. But is there a third way for those who wish to rediscover the sacred in a skeptical society? What kind of faith, if any, can be proclaimed after the ravages of the Holocaust and the many religion-based (...) terrors since? Richard Kearney explores these questions with a host of philosophers known for their inclusive, forward-thinking work on the intersection of secularism, politics, and religion. An interreligious dialogue that refuses to paper over religious difference, these conversations locate the sacred within secular society and affirm a positive role for religion in human reflection and action. Drawing on his own philosophical formulations, literary analysis, and personal interreligious experiences, Kearney develops through these engagements a basic gesture of hospitality for approaching the question of God. His work facilitates a fresh encounter with our best-known voices in continental philosophy and their views on issues of importance to all spiritually minded individuals and skeptics: how to reconcile God's goodness with human evil, how to believe in both God and natural science, how to talk about God without indulging in fundamentalist rhetoric, and how to balance God's sovereignty with God's love.

Abstract: The symmetry argument is an objection to the 'deprivation approach'– the account of badness favored by nearly all philosophers who take death to be bad for the one who dies. Frederik Kaufman's recent response to the symmetry argument is a development of Thomas Nagel's suggestion that we could not have come into existence substantially earlier than we in fact did. In this paper, I aim to show that Kaufman's suggestion fails. I also consider several possible modifications of his theory, (...) and argue that they are unsuccessful as well. (shrink)

In early modernity, one can find many spatial logic diagrams whose geometric forms share a family resemblance with religious art and symbols. The family resemblance these diagrams bear in form is often based on a vesica piscis or on a cross: Both logic diagrams and spiritual symbols focus on the intersection or conjunction of two or more entities, e.g. subject and predicate, on the one hand, or god and man, on the other. This paper deals with the development and function (...) of logic diagrams, their analogy to religious art and symbols, and their modern application in artificial intelligence. (shrink)

The paper examines Schopenhauer's logic lectures and the eristic dialectics of the manuscript remains in particular. The content of the logic lectures is briefly presented, then the characteristics are highlighted and finally Schopenhauer’s Euler diagrams are examined. The section on eristic dialectics summarizes the history of the text and its origin and reflects the content and order of the document.

The paper presents the diagrammatic calculus CL, which combines features of tree, Euler-type, Venn-type diagrams and squares of opposition. In its basic form, `CL' (= Cubus Logicus) organizes terms in the form of a square or cube. By applying the arrows of the square of opposition to CL, judgments and inferences can be displayed. Thus CL offers on the one hand an intuitive method to display ontologies and on the other hand a diagrammatic tool to check inferences. The paper focuses (...) mainly on the adaptation of the square of opposition in CL and offers an algebraic notation, which corresponds to the diagrammatic representation. (shrink)

In the second preface to the Critique of Pure Reason, Kant claims that Galileo Galilei, Evangelista Torricelli and Georg Ernst Stahl caused a scientific revolution in experimental physics (B xii). In this paper, I advance the historical thesis that Kantʼs claim refers precisely to three passages from Discursus et demonstrationes mathematicae (Galilei), Lettera a Filaleti Di Timauro Antiate (Torricelli), and Beweiß von den Saltzen (Stahl). This historical thesis provides evidence for a newer systematic interpretation, which says that the topic of (...) the second preface is not epistemological, but rather methodological. (shrink)

Japanese translation of ""Schopenhauers Gebrauchstheorie der Bedeutung und das Kontextprinzip. Eine Parallele zu Wittgensteins Philosophischen Untersuchungen". In: 97. Schopenhauer-Jahrbuch (2016), S. 29–51" by Tadahiro Oota (太田 匡洋 [訳]).

In previous research, Schopenhauer is regarded as a consistent representative of a classical picture theory of language. The paper shows, however, that Schopenhauer does not only present a use theory of meaning in his lectures on logic, but also justifies it with the help of the context principle. Furthermore, it is discussed to what extent Schopenhauer's use theory of meaning is similar to the semantic theory of Ludwig Wittgenstein and his successors.

A particularly promising trail on the search for forgotten logic diagrams leads to Upper Lusatia in the 17th century, more precisely to Christian Weise and his students. Samuel Grosser, who later became rector in Görlitz, and Johann Christian Lange, who later became professor of logic at the University of Gießen, are the most prominent to have published remarkable logic diagrams. Even more remarkable, however, is the fact that Lange's interest in these diagrams ultimately gave rise to the idea of building (...) a logic machine. (shrink)

Aufstieg zum Einen - das ist das Zentrum der Philosophie Plotins und des von ihm ausgehenden Neuplatonismus. Dass solcher Aufstieg zum Einen aber auch schon bei Platon eine zentrale Rolle spielt, gehört zu den wichtigsten Einsichten der neueren Platonforschung. Das vorliegende Buch zieht daraus die Konsequenz und bestimmt das Verhältnis zwischen Platon und dem Neuplatonismus neu. Es verbindet die erste umfassende Darstellung von Plotins Theorie des Absoluten mit einer Rekonstruktion von Platons Henologie. Dabei arbeitet es die enge Verbindung beider heraus (...) und macht zugleich die bleibende philosophische Relevanz des Themas deutlich. (shrink)

Many philosophers maintain that artworks, such as statues, are constituted by other material objects, such as lumps of marble. I give an argument against this view, an argument which appeals to mereological simples.

The so-called 'Extreme Claim' asserts that reductionism about personal identity leaves each of us with no reason to be specially concerned about his or her own future. Both advocates and opponents of the Extreme Claim, whether of a reductionist or non-reductionist stripe, accept that similar problems do not arise for non-reductionism. In this paper I challenge this widely held assumption.

A widely debated question in current research centres on determining the precursors to G. W. F. Hegel's theory of recognition. Until now Fichte, Rousseau and Aristotle have been discussed. However, the present paper analyses a further surprising correspondence between Marsilio Ficino's theory of love and Hegel's theory of recognition. Here it is shown that Hegel studied Ficino in 1793 and that we can discover syntactical, semantical, and structural vestiges of Ficino's De amore II 8 in Hegel's early fragments on religion (...) (1793) and love (1797), which are closely related to the general theory of recognition found in the Phenomenology of Spirit. Not only may this thesis be relevant for Hegel or Ficino scholarship, but it could also be a further indication that social theories with normative content are an integral characteristic of (early) modern self-consciousness.

In this paper we present an overview of the current interpretations of the first volume of Arthur Schopenhauer’s main work The World as Will and Representation (W I) and discuss their problems. We discuss four issues, which in our opinion must clarify a current interpretation implicitly or explicitly, if it claims to be an interpretation of the whole book: (1) What does Schopenhauer mean by the fact that his work shares only one (single) thought? (2) How are the individual books (...) of W I related? (3) Do we have to read Schopenhauer’s W I as a normative guide to the denial of will-to-live or as a neutral description of the world? (4) Do the often discussed contradictions and aporias within the book follow a plan or are they errors of thought? (shrink)
