This proposed study would seek to test for a causal relationship between theory of mind (ToM) and consciousness by conducting a single-variable experiment. Further, the theory proposed to explain this relationship includes that it must exist as a quantum superposition. The independent variable of ToM would be manipulated by randomly assigning participants to two groups. The two groups would represent a higher and lower level of the ToM variable by exposing participants to dramatic material chosen, in the first group, to (...) evoke ToM at a high level; and in the second group, at a lower level. After viewing the material, subjects would receive the Reading the Mind in the Eyes Test (RMET) for theory of mind, demonstrating a higher and lower level of ToM corresponding to which material they viewed. The participants would then complete the Phenomenology of Consciousness Inventory (PCI). The researcher would then compare the scores on the PCI between the two groups, using appropriate statistical tests. If there is a statistically significant difference between the groups, it would suggest that the presence of theory of mind causes the existence of consciousness. (shrink)

To create fair and accountable AI and robotics, we need precise regulation and better methods to certify, explain, and audit inscrutable systems.

Since approval of the EU General Data Protection Regulation (GDPR) in 2016, it has been widely and repeatedly claimed that the GDPR will legally mandate a ‘right to explanation’ of all decisions made by automated or artificially intelligent algorithmic systems. This right to explanation is viewed as an ideal mechanism to enhance the accountability and transparency of automated decision-making. However, there are several reasons to doubt both the legal existence and the feasibility of such a right. In contrast to the (...) right to explanation of specific automated decisions claimed elsewhere, the GDPR only mandates that data subjects receive meaningful, but properly limited, information (Articles 13-15) about the logic involved, as well as the significance and the envisaged consequences of automated decision-making systems, what we term a ‘right to be informed’. Further, the ambiguity and limited scope of the ‘right not to be subject to automated decision-making’ contained in Article 22 (from which the alleged ‘right to explanation’ stems) raises questions over the protection actually afforded to data subjects. These problems show that the GDPR lacks precise language as well as explicit and well-defined rights and safeguards against automated decision-making, and therefore runs the risk of being toothless. We propose a number of legislative and policy steps that, if taken, may improve the transparency and accountability of automated decision-making when the GDPR comes into force in 2018. (shrink)

In October 2016, the White House, the European Parliament, and the UK House of Commons each issued a report outlining their visions on how to prepare society for the widespread use of artificial intelligence. In this article, we provide a comparative assessment of these three reports in order to facilitate the design of policies favourable to the development of a ‘good AI society’. To do so, we examine how each report addresses the following three topics: the development of a ‘good (...) AI society’; the role and responsibility of the government, the private sector, and the research community in pursuing such a development; and where the recommendations to support such a development may be in need of improvement. Our analysis concludes that the reports address adequately various ethical, social, and economic topics, but come short of providing an overarching political vision and long-term strategy for the development of a ‘good AI society’. In order to contribute to fill this gap, in the conclusion we suggest a two-pronged approach. (shrink)

At the opening of her article, Acker writes, "I am using this essay to do two things. To read a short passage from Philosophy in the Bedroom by the Marquis de Sade. To read one of his tales. The more that I write my own novels, the more it seems to me that to write is to read." The two main divisions in the text bear the following headings: "To write in order to lead the reader into a labyrinth from (...) which the reader cannot emerge without destroying the world" and "Reading a tale by de Sade: writing or reading whose only purpose is to destroy itself.".

Boredom has dominated discussions about longevity thanks to Bernard Williams’s influential “The Makropulos Case.” I reveal the presence in that paper of a neglected, additional problem for the long-lived person, namely alienation in the face of unwanted change. Williams gestures towards this problem but does not pursue it. I flesh it out on his behalf, connecting it to what I call the ‘curmudgeonly attitude to change.’ This attitude manifests itself in the tendency, amongst those getting on in years, to observe (...) that things are getting worse. Curmudgeonliness is typically met with dismissal because it often concerns changes that don’t radically inhibit the curmudgeon’s well-being or autonomy. I believe that taking the curmudgeonly attitude more seriously will provide insight into the longer-lived self and its relation to the future. Using Williams’s approach to longevity as the framework, I contend that—as with boredom—a sense of alienation born of curmudgeonliness can become terminal for the subject, rendering her unable to envision the future as a site of worthwhile activity. However, I also uncover ways in which this agential stasis is significantly distinct from boredom and constitutes a different worry and a different risk for the long-lived individual. (shrink)

This article introduces the notion of the directedness of a process, which underlies event causation as well as the persistence of things. Using this notion it investigates what happens in typical cases of active event causation. Causes never necessitate their effects because even non- probabilistic causes can be counteracted.

While other philosophers have pointed out that Libet's experiment is compatible with compatibilist free will and also with weak libertarian free will, this article argues that it is even compatible with strong libertarian free will (SLF), \ie a person's ability to initiate causal processes. Contrary to what Libet suggested, the actions in the experiment were motivated by urges. It is in accordance with SLF that the urges had preceding unconcious causes. Furthermore, Libet's observation that vetoing is possible confirmes SLF.

In information societies, operations, decisions and choices previously left to humans are increasingly delegated to algorithms, which may advise, if not decide, about how data should be interpreted and what actions should be taken as a result. More and more often, algorithms mediate social processes, business transactions, governmental decisions, and how we perceive, understand, and interact among ourselves and with the environment. Gaps between the design and operation of algorithms and our understanding of their ethical implications can have severe consequences (...) affecting individuals as well as groups and whole societies. This paper makes three contributions to clarify the ethical importance of algorithmic mediation. It provides a prescriptive map to organise the debate. It reviews the current discussion of ethical aspects of algorithms. And it assesses the available literature in order to identify areas requiring further work to develop the ethics of algorithms.

This article criticises Alvin Plantinga’s claim that ‘basic’ design beliefs, which arise without a conscious inference, have more positive epistemic status than non-basic ones and that we cannot evaluate the probabilities involved in inferential, inductive design arguments.

Some have tried to make miracles compatible with the laws of nature by re-defining them as something other than interventions. By contrast, this article argues that although miracles are divine interventions, they are not violations of the laws of nature. Miracles are also not exceptions to the laws, nor do the laws not apply to them. The laws never have exceptions; they never are violated or suspended, are probably necessary and unchangeable, and apply also to divine interventions. We need to (...) reconsider not miracles but laws. The main claim of this article is that laws of nature do not entail regularities, and therefore that miracles do not violate the laws. We need a new theory of the laws of nature: the tendency theory. (shrink)

The claim of this article is that no event can determine a later event and that in this sense there cannot be sufficient causes. Therefore the causal structure of the world does not exclude free will, even if there are no chance processes.

Friedrich Schleiermacher suggested that his project was to make Christianity compatible with reason and with the natural sciences. This article argues that Schleiermacher re- jected Christian doctrine und developed a religion which he called ‘Christian’ but which does not contain the Chris- tian doctrine and which is not rational. The article sketches Schleiermachers rejection of Christian doctrine, examines his claim that the natural sciences exclude miracles, criti- cises Schleiermachers non-cognitivism, and sketches the role of doctrine in Christianity.

‘Enlightenment’ (in German, ‘Aufklärung’) is not simply the name of a movement or development whose existence is uncontroversial. Rather, the claim ‘The 18th century was the age of enlightenment’ or ‘In Germany, there was the Enlightenment’ entail certain claims which need to be discussed. This article argues that some of these claims are false and that therefore the claim ‘The Enlightenment does not exist’ is true.

Einige versuchen, Wunder mit den Naturgesetzen vereinbar zu machen, indem sie „Wunder“ als etwas anderes als göttliche Eingriffe definieren. Dieser Aufsatz behauptet hin- gegen, daß Wunder die Naturgesetze nicht verletzen, obwohl sie göttliche Eingriffe sind. Wunder sind auch keine „Ausnah- men“ der Naturgesetze, noch treffen die Naturgesetze nicht auf sie zu. Naturgesetze haben nie Ausnahmen, sie werden nie verletzt oder ausgesetzt, sie sind wahrscheinlich notwen- dig und unveränderlich, und sie treffen auch auf göttliche Ein- griffe zu. Wir sollten nicht unsere (...) Vorstellung von Wundern, sondern unsere Vorstellung der Naturgesetze in Frage stel- len. Die Hauptthese dieses Aufsatzes ist, daß Naturgesetze keine Abfolgeregelmäßigkeiten implizieren und daß deshalb Wunder die Naturgesetze nicht verletzen. Wir brauchen eine neue Theorie der Naturgesetze: die Tendenztheorie. (shrink)

Dieser Aufsatz hält der Meinung, daß die Analytische Religionsphilosophie zu rationalistisch sei, entgegen, daß es auch in Sachen Religion nicht zu viel Vernunft geben kann. Dies begründe ich, indem ich das Zweistufenmodell des christlichen Glaubens verteidige, nach dem der christliche Glaube einerseits aus dem Annehmen einer metaphysischen Lehre und andererseits aus einer darauf gründenden Hingabe besteht. Dies ist ein Kennzeichen einer sowohl tiefen als auch rationalen Religion.

Die liberale Theologie geht davon aus, daß man die traditionelle christliche Lehre heute nicht mehr glauben kann und daß man sie deshalb verändern muß. Sie will sich nicht vom Christentum offen absagen, sondern das Christentum verändern oder eine neue Version des Christentums einführen. Radical Orthodoxy (RO), vor allem von John Milbank gegründet, will eine Gegenbewegung dazu sowie zum Säkularismus sein: „A theology which claims to be radical and orthodox“. In diesem Aufsatz möchte ich untersuchen, ob sie es wirklich ist, und (...) ich werde Indizien dafür vorstellen, daß sie es nicht ist. Vor diesem Hintergrund werde ich dann die Analytische Religionsphilosophie (oder Analytische Theologie) als Alternative vorstellen. (shrink)

English: Between 1960 and 2000 many German-speaking professors of philosophy confined their research to the history of philosophy, they did not defend their own answers to philosophical questions. This article describes some possible causes of this phenomenon, makes a plea for defending answers to philosophical questions, and gives some guidelines for doing so which anticipate some objections. -/- German: Zwischen 1960 und 2000 beschränkten sich viele deutschsprachige Philosophieprofessoren auf Philosophiegeschichtsschreibung, sie verteidigten nicht ihre eigenen Antworten auf philosophische Fragen.

Zwischen 1960 und 2000 beschränkten sich viele deutsch- sprachige Philosophieprofessoren auf Philosophiegeschichts- schreibung, sie verteidigten nicht ihre eigenen Antworten auf philosophische Fragen.

Bei der Renaissance der philosophischen Auseinandersetzung mit Fragen über Gott spielte der Oxforder Philosoph Richard Swinburne eine wesentliche Rolle. Er kann als der bedeutendste zeitgenössische Vertreter der natürlichen Theologie gelten. Natürliche Theologie ist das Unternehmen, philosophisch zu untersuchen, ob es einen Gott gibt und wie er beschaffen ist. Dies ›philosophisch‹ und nicht theologisch zu untersuchen, heißt, direkte Offenbarung dabei nicht als Erkenntnisquelle zu verwenden.

If God brings about an event in the universe, does it have a preceding cause? For example, if the universe began with the Big Bang and if God brought it about, did the Big Bang then have a preceding cause? The standard answer is: yes, it was caused by a divine willing. I propose an alternative view: God’s actions, unlike human actions, are not initiated by willings, undertakings, or volitions, but God brings about the intended event directly. Presenting a solution (...) to the dilemma of free will I explain what ‘bringing about directly’ means and show that the question of what an action begins with is distinct from the question whether it is a basic action.

After a general remark about Armstrong’s conception of ontology, I raise objections against this view and defend an alternative account of the connection between particulars and their properties, involving a kind of ontological dependence which is different from Armstrong’s necessary connection between particulars and their properties.

This article argues that agents can initiate causal processes.

Recent empirical research has substantiated the finding that very many of us harbour implicit biases: fast, automatic, and difficult to control processes that encode stereotypes and evaluative content, and influence how we think and behave. Since it is difficult to be aware of these processes - they have sometimes been referred to as operating 'unconsciously' - we may not know that we harbour them, nor be alert to their influence on our cognition and action. And since they are difficult to (...) control, considerable work is required to prevent their influence. We here focus on the implications of these findings for epistemology. We first look at ways in which implicit biases thwart our knowledge seeking practices (sections 1 & 2). Then we set out putative epistemic benefits of implicit bias, before considering ways in which epistemic practices might be improved (section 3). Finally, we consider the distinctive challenges that the findings about implicit bias pose to us as philosophers, in the context of feminist philosophy in particular (section 4). (shrink)

This article argues against Benjamin Libet's claim that his experiment has shown that our actions are caused by brain events which begin before we consciously undertake the action. It clarifies what exactly should be meant by saying that the readiness potential causes, initiates, or prepares an action. It shows why Libet's experiment does not support his claim and why the experiments by Herrmann et al. and by Trevena \& Miller provide evidence against it. The empirical evidence is compatible with strong (...) libertarian free will. Neither the readiness potential nor the lateralized readiness potential cause our actions. (shrink)

This article presents Roman Ingarden’s theory of causation, as developed in volume III of The Controversy about the Existence of the World, and defends analternative which uses some important insights of Ingarden. It rejects Ingarden’s claim that a cause is simultaneous with its effect and that a cause necessitates its effect. It uses Ingarden’s notion of ‘inclinations’ and accepts Ingarden’s claim that an event cannot necessitate a later event.

This paper argues that there are true synthetic modal claims and that modal questions in philosophy in general are to be interpreted not in terms of logical necessity but in terms of synthetic necessity. I begin by sketching the debate about modality between logical positivism and phenomenology. Logical empiricism taught us to equate being tautological with being necessary. The common view is that tautologies are necessary in the narrow sense but that there is also necessity in a wider sense. I (...) argue against this that we should distinguish necessity from analyticity and possibility from consistency. (shrink)

It is the conclusion advanced in this paper that there is a necessary and sufficient causal relationship between theory of mind and the neurological creation of conscious and unconscious quantum logic existing in superposition in the human brain. It takes two intelligent agents to make one self-aware agent. -/- A key element of my reasoning is the instantiation of superposition by way of a logical device I call the “state-system.” The newly conscious human remains unaware of the inner transformation caused (...) by theory of mind because, unlike a change of state within a quantum system, a change in the system itself is unobservable from within the system. This hides the dual nature of human self-awareness and preserves superposition with the unconscious. Only the internal state of the other is observed to start. The simultaneous split creating consciousness and the unconscious is not observed. Further, once this superposition is observed, it is suggested that human consciousness achieves a new state that is the next step in the evolution of human experience; quantum interbeing. The result of quantum consciousness is the ability to perceive superposition without reducing it into one of its components, while maintaining the integrity of each. It also confirms freedom of choice. After learning to hold two ideas simultaneously, the mind experiences itself as free by virtue of its ability to choose sides in the moment of observation, eliminating the quantum firewall that is determinism. -/- We start by looking at four key scientific works: the 1978 Vernon Mountcastle paper, the Sebastian Schepis paper of 2023, and the recent work of Allan Schore, all resting upon the well-known foundational quantum mechanical interpretation of Carlo Rovelli. They are each connected in indirect but profound ways. In the Mountcastle, it is argued that intelligence is a matter of scale—an argument based on the uniform appearance of all functionally unique command centers in the neocortex, and of their universal constituents: cortical columns. In the Schepis, it is argued that consciousness is a quantum phenomenon that requires the existence of two intelligent agents in logical superposition. And in the work of Schore, the key direction in neuropsychological research is established as interpersonal neurobiology and—implicitly—theory of mind. -/- These works collectively support a path to quantum consciousness as the logical consequence of intelligence scaling. Its implications include the invalidation of the ontological basis of the science of physics. Physical existence is real, but only as a metaphor for quantum informational processes. In his seminal 1996 paper “Relational Quantum Mechanics” Carlo Rovelli laid down the bedrock upon which my conclusions rest. In it he proposes that the reader “consider a reformulation of quantum mechanics in terms of information theory.” He posits that physical objects are not real. Only interactions between nodes in the network of quantum information are fundamental. He thus nullifies the measurement problem in quantum mechanics and shifts its ontology from the physical to the informational. -/- This paper seeks to validate his proposal while establishing the logical inevitability of human quantum consciousness as a consequence of the diverse but convergent research cited here. (shrink)

The correlation between quantum phenomena and information is explored using relational quantum mechanics (RQM) and quantum monism as potential frameworks for understanding informational reality's emergence from the merely physical. Emphasizing a top-down approach, the paper advocates applying knowledge of quantum components to our classical world. It highlights the contributions of researchers such as Rovelli, Wheeler, and Everett, who have made strides in this direction. -/- The paper elucidates the duality of quantum states as counterintuitive when applied to physical objects but (...) comprehensible as information. It questions the necessity of deferring to an external reality and urges a pragmatic approach to constructing our understanding of reality. Quantum computation's significance is emphasized, as it bridges physical and informational aspects of reality. -/- Ultimately, the paper envisions a transformative world in which human hands shape physical reality by harnessing the potential of quantum computation and delving into Planck's energy-time relation. In this paradigm shift, traditional aspirations of understanding the fundamental secrets of the physical world, as envisioned by Einstein, may fade, giving rise to a new era of unforeseen peace, fulfillment, and adventure.

Many authors hold that we cannot have the kind of free will that we seem to have. This article spells out and defends that kind of free will. Most libertarians hold that a free action involves a probabilistic process at some stage. Like the compatibilists, I hold that this is not only not required for free will but even reduces or excludes freedom. But contrary to the compatibilist and contrary to most libertarians, I claim that free will requires that we (...) can bring about events that have no preceding cause. That is what our experience suggests, and there are no beliefs that contradict this and are justified. (shrink)

Review of Gottesbeweise als Herausforderung für die moderne Vernunft, ed. Th. Buchheim.

Albrecht von Wachters Studie Eine philosophische Untersuchung des Neuen Coronavirus (von Anfang Juni 2020) zufolge kann selbst ein gut informierter Laie erkennen, dass das Neuartige Coronavirus nicht besonders gefährlich ist. Ohne Widerspruch dazu lässt sich behaupten, dass ein Virus, das eine wichtige, sine qua non Bedingung einer weltweiten Krise ist, zurecht als hochgradig gefährlich beurteilt wird. Denn der Neuartige Coronavirus ist nicht nur gefährlich für die Gesundheit, sondern auch für Politik und Wirtschaft, wobei letzteres natürlich maßgeblich von der Beurteilung des (...) ersteren abhängt. Aber auch betreffend der Gefährlichkeit des Virus für ein und dasselbe kann man auf Basis derselben Informationen zu verschiedenen Ergebnissen kommen, und zwar, wenn verschieden Maß genommen wird, und dieses Maß ist der angewandte Gefahrenbegriff. In diesem Aufsatz werde ich argumentieren, dass der Gefahrenbegriff der genannten Studie zu eng ist, um die mit dem Neuartigen Coronavirus verbundenen Gefahren für die menschliche Gesundheit korrekt beurteilen zu können. Menschen mussten schon immer auf der Hut sein und wir verstehen uns ganz gut auf Gefahren im allgemeinen. Von diesem allgemeinen Gefahrenbegriff ausgehend werden einige Binsenweisheiten zur Gefährlichkeit des Neuartigen Coronavirus vorgetragen. (shrink)

În acest articol încerc să argumentez opinia că, așa cum este definită eugenia, este foarte dificil de făcut o diferențiere clară între știință (medicină, ingineria genetică) și eugenie. Și de stabilit o linie peste care ingineria genetică nu ar trebui să treacă, conform unor norme morale, juridice și religioase. Atâta timp cât acceptăm ajutorul geneticii în găsirea unor modalități de combatere a cancerului, diabetului sau HIV, acceptăm în mod implicit și eugenia pozitivă, conform definiției actuale. Și atâta timp cât acceptăm (...) screening-ul genetic, și intervenții asupra fătului nenăscut, sau avortul, acceptăm în mod implicit și eugenia negativă. În plus, la nivel de guverne, deși oficial eugenia este repudiată, ea a fost legalizată în foarte multe țări până de curând, și încă mai este acceptată și legalizată, chiar dacă în forme mai subtile, și în prezent. În Introducere definesc termenul și modurile de clasificare. Urmează Istoria eugeniei pornind din perioada antică, introducerea eugeniei de Francis Galton, practica eugeniei ca politică de stat în diverse țări, și eugenia actuală (eugenia liberală). Analizez apoi diverse probleme ridicate de Etica eugeniei liberale, și am dezvoltat o secțiune aparte pentru Viitorul eugeniei, cu accent pe proiectul genomului uman. În final, în secțiunea Concluzii expun opiniile personale cu privire la practica actuală a eugeniei. Am folosit ca surse principale de investigație articolele lui Kenneth M.

Critical notice of Puddifoot, Katherine. 2021. How Stereotypes Deceive Us. NY: OUP.--------- -/- Kathy Puddifoot makes a compelling and enlightening case for a striking pair of claims: 1) false stereotypes sometimes steer us to the truth, while 2) true stereotypes often lead us into error. This is a wonderful book, a seamless integration of epistemology with ethics, of philosophy with social science, and of “mainstream” or “Western analytic” approaches with marginalized and underappreciated contributions from critical social traditions, especially black (...) feminism. The integrations are so seamless, in fact, as to give the reader the impression that Puddifoot is simply picking up conversations already underway. Instead, she has done a tremendous service in bringing representatives from wide-ranging, often-siloed disciplines into dialogue. Another virtue of Puddifoot’s book is how thoroughly it maps out the actual and possible views and logical spaces revolving around each topic she addresses. How Stereotypes Deceive Us could therefore be used to introduce budding epistemologists to the field, as it offers clear and careful explanations of leading approaches to a range of topics, including virtue epistemology, theory of mind, and more.

In the first part of this paper we will consider the likely extent of Spinoza’s exposure to Kabbalistic literature as he was growing up in Amsterdam. In the second part we will closely study several texts in which Spinoza seems to engage with Kabbalistic doctrines. In the third and final part we will study the role of the two crucial doctrines of emanation and pantheism (or panentheism), in Spinoza’s system and in the Kabbalistic literature.

Grounded theory methodology is perceived as challenging due to its systematic and rigorous process. However, this is because most people do not realize that the strategies used in the grounded theory data analysis process are used by laypeople and professionals regularly, if not daily. This article aims to help others interested in grounded theory with a background in qualitative data analysis feel comfortable engaging in the methodology and constructing multiple theories in the same study. It shares my latest experience incorporating (...) various data analysis strategies with the constructivist approach: holistic and systems thinking, situational analysis, dramaturgical analysis, perspective taking, and abstraction. The examples remove the mystery from abstraction and abductive reasoning. (shrink)
