One of the hardest questions to answer for a (Neo)platonist is to what extent and how the changing and unreliable world of sense perception can itself be an object of scientific knowledge. My dissertation is a study of the answer given to that question by the Neoplatonist Proclus (Athens, 411-485) in his Commentary on Plato’s Timaeus. I present a new explanation of Proclus’ concept of nature and show that philosophy of nature consists of several related subdisciplines matching the ontological stratification (...) of nature. Moreover, I demonstrate that for Proclus philosophy of nature is a science, albeit a hypothetical one, which takes geometry as its methodological paradigm. I also offer an explanation of Proclus’ view of what is later called the mathematization of physics, i.e. the role of the substance of mathematics, as opposed to its method, in explaining the natural world. Finally, I discuss Proclus’ views of the discourse of philosophy of nature and its iconic character. (shrink)

Proclus was one of the last great philosophers of Antiquity. His legacy in the cultural history of the west can hardly be overestimated. This book is the most comprehensive guide to Proclus' life, thought and legacy that is currently available.

In this paper I show that Proclus is an adherent of the Classical Model of Science as set out elsewhere in this issue (de Jong and Betti 2008), and that he adjusts certain conditions of the Model to his Neoplatonic epistemology and metaphysics. In order to show this, I develop a case study concerning philosophy of nature, which, despite its unstable subject matter, Proclus considers to be a science. To give this science a firm foundation Proclus distills from Plato’s Timaeus (...) the basic concepts Being and Becoming and a number of basic propositions, among others the quasi-definitions of the basic concepts. He subsequently explains the use of these quasi-definitions, that are actually epistemic guides, in such a way that he obtains a connection between a rational and an empirical approach to the natural world. A crucial task in establishing the connection is performed by the faculty of doxa and by geometrical conversion. The result is that Proclus secures a universal, necessary and known foundation for all of philosophy of nature. (shrink)

This chapter provides an analysis of the often mentioned but rarely explained ‘systematicity’ of Proclus’ version of Neoplatonism, and an introduction into the basics of his metaphysics. Starting from the assumption that any philosophical system stems from the desire for explanations, and that for Platonists this involved bridging the opposition between explanandum and explanans, it formulates a number of ensuing requirements, which lead to the construction of what is generally called a philosophical system. The authors then show how this pans (...) out in Proclus’ metaphysics, specifically the One, causality, and triads. Finally, they address the relevance of all this for human life, and briefly evaluate the downsides of Proclus’ systematicity and what sets him apart from predecessors. (shrink)

In late antiquity, logic developed into what Ebbesen calls the LAS, the Late Ancient Standard. This paper discusses the Neoplatonic use of LAS, as informed by epistemological and metaphysical concerns. It demonstrates this through an analysis of the late ancient debate about hypothetical and categorical logic as manifest in the practice of syllogizing Platonic dialogues. After an introduction of the Middle Platonist view on Platonic syllogistic as present in Alcinous, this paper presents an overview of its application in the syllogizing (...) practice of Proclus and others. That overview shows that the two types were considered two sides of the same coin, to be used for the appropriate occasions, and both relying on the methods of dialectic as revealing the structure of knowledge and reality. Pragmatics, dialectic, and didactic choices determine which type or combination is selected in syllogizing Plato. So even though there is no specific Neoplatonic logic, there is a specific Neoplatonic use of LAS. (shrink)

Aristotle described the scientific explanation of universal or general facts as deducing them through scientific demonstrations, that is, through syllogisms that met requirements he first formulated of logical validity and explanatoriness. In Chapters 19-23, he adds arguments for the further logical restrictions that scientific demonstrations can neither be indefinitely long nor infinitely extendible through the interposition of new middle terms. Chapters 24-26 argue for the superiority of universal over particular demonstration, of affirmative over negative demonstration, and of direct negative demonstration (...) over demonstration to the impossible. Chapters 27 34 discuss different aspects of sciences and scientific understanding, allowing us to distinguish between sciences, and between scientific understanding and other kinds of cognition, especially opinion. Philoponus' comments on these chapters are interesting especially because of his metaphysical analysis of universal predication and his understanding of the notion of subordinate sciences. We learn from his commentary that Philoponus believed in Platonic Forms as inherent in, and posterior to, the Divine Intellect, but ascribed to Aristotle an interpretation of Plato's Forms as independent substances, prior to the Demiurgic Intellect. A very important notion from Aristotle's Posterior Analytics is that of the 'subordination' of sciences, i.e. the idea that some sciences depend on 'higher' ones for some of their principles. Philoponus goes beyond Aristotle in suggesting a taxonomy of sciences, in which the subordinate science is the same in genus as the superordinate, but different in species. (shrink)

This volume collects Late Ancient, Byzantine and Medieval appropriations of Aristotle's Posterior Analytics, addressing the logic of inquiry, concept formation, the question whether metaphysics is a science, and the theory of demonstration.

When talking about decisionmaking for children with a life-threatening condition, the death of children with brain tumors deserves special attention. The last days of the lives of these children can be particularly harsh for bystanders, and raise questions about the suffering of these children themselves. In the Netherlands, these children are part of the group for whom a wide range of end-of-life decisions are discussed, and questions raised. What does the end-of-life for these children look like, and what motivates physicians (...) and parents to make decisions that may affect the life and death of these children? This article highlights the story of the parents of the sisters Roos and Noor. When both their daughters were diagnosed with a hereditary brain tumor, they had to make similar decisions twice. Their story sheds light on the suffering of children in the terminal phase, and how this suffering may motivate parents and physicians to make decisions that influence the end of life of these children’s lives.We argue that complete knowledge about suffering in the terminal phase of children with brain tumors is impossible. However, by collecting experiences like those of Roos and Noor, we can move toward an experienced-based understanding and better guide parents and physicians through these hardest of decisions.

This reflection focuses on what insights Catholic Social Teaching can provide for corporate governance. I argue that the ‘standard’ agency theory is overly reductionist and insufficiently incorporates important economic limitations as well as human frailty. As a result, such agency theory insufficiently distinguishes firms from markets, which can easily relativize how we treat others and facilitate rationalization of unethical behavior. I then explore how three pillars of CST—human dignity, solidarity, and subsidiarity—can help overcome these limitations. CST proposes a vision of (...) the business corporation as a community of persons, working together in cooperative business relationships toward the shared purpose of contributing to human flourishing.

Psycholinguistic studies often look at the production of referring expressions in interactive settings, but so far few referring expression generation algorithms have been developed that are sensitive to earlier references in an interaction. Rather, such algorithms tend to rely on domain-dependent preferences for both content selection and linguistic realization. We present three experiments showing that humans may opt for dispreferred attributes and dispreferred modifier orderings when these were primed in a preceding interaction (without speakers being consciously aware of this). In (...) addition, we show that speakers are more likely to produce overspecified references, including dispreferred attributes (although minimal descriptions with preferred attributes would suffice), when these were similarly primed.

Standardisation is increasingly seen as a means to insert ethics in innovation processes. We examine the institutionalisation of responsible innovation in de jure standardisation as this is an important but unexplored research area. In de jure standardisation, stakeholders collaborate in committees to develop standards. We adopt the anticipation, inclusion, reflexivity, and responsiveness responsible innovation framework as our theoretical lens. Our study suggests that responsible standardisation processes should embody forms of these four dimensions. We investigate the institutionalisation of these dimensions and (...) identify 96 factors that can motivate, hinder, or facilitate responsible standardisation. Factors were found through in-depth interviews with managers of a standard developing organisation. These are subsequently validated/rejected using surveys completed by committee representatives. The results suggest that the social desirability of standards is not self-evident. This study could pave the way for future research on responsible standardisation processes, complementing research on legitimacy, responsible innovation, and standardisation. (shrink)

Background In the Netherlands, people can receive (limited) demedicalised assistance in suicide (DAS)—an option less well known than physician-assisted dying (PAD). Aim This study explores which trajectories people take to seek DAS, through open-coding and inductive analysis of in-depth interviews with 17 people who receive(d) DAS from counsellors facilitated by foundation De Einder. Results People sought DAS as a result of current suffering or as a result of anticipating possible prospective suffering. People with current suffering were unable or assumed they (...) would be unable to obtain PAD. For people anticipating possible prospective suffering, we distinguished two trajectories. In one trajectory, people preferred PAD but were not reassured of help by the physician in due time and sought DAS as a backup plan. In the other trajectory, people expressed a preference for DAS mainly as a result of emphasising self-determination, independence, taking their own responsibility and preparing suicide carefully. In all trajectories, dissatisfaction with physician–patient communication—for instance about (a denied request for) PAD or fearing to discuss this—influenced the decision to seek DAS. Conclusions While PAD is the preferred option of people in two trajectories, obtaining PAD is uncertain and not always possible. Dissatisfaction with physician–patient communication can result in the physician not being involved in DAS, being unable to diagnose diseases and offer treatment nor offer reassurance that people seem to seek. We plea for more mutual understanding, respect and empathy for the limitations and possibilities of the position of the physician and the patient in discussing assistance in dying. (shrink)

Contextualist theories of knowledge have received a lot of attention in the contemporary epistemological literature. The central idea of such theories is that contextual factors play an important role in determining whether a particular knowledge sentence is true or false. Thus, on contextualist theories of knowledge it might be the case that a particular subject knows a proposition in one context but fails to know that same proposition in another context—while the only thing that has changed is the context. Of (...) the extant contextualist theories of knowledge, attributer contextualism (that is, the type of contextualism that makes the context of the attributer of knowledge crucial in determining whether a subject knows a proposition) has been discussed the most. The papers in the present collection continue this focus on attributer contextualism, and offer a fairly critical treatment of this theory. Nevertheless, a number of papers also outline _new_ types of contextualism. What results is a collection of papers that, though negative towards attributer contextualism, for the most part is sympathetic towards contextualism in general. (shrink)

This article offers a critical reading of three major biographies of the British novelist and philosopher Iris Murdoch. It considers in particular how a limited concern for gender issues has hampered their portrayals of Murdoch as a creator of images and ideas. The biographies are then contrasted to a biographical sketch constructed from Murdoch's philosophical writing. The assessment of the biographies is set against the larger background of the relation between women and philosophy. In doing so, the paper offers a (...) critical response to Sally Haslanger's recent “Musings” (Haslanger 2008), which is contrasted to Virginia Woolf's A Room of One's Own (1929) and Michèle Le Doeuff's Hipparchia's Choice (2007).

A decade ago, Isham and Butterfield proposed a topos-theoretic approach to quantum mechanics, which meanwhile has been extended by Döring and Isham so as to provide a new mathematical foundation for all of physics. Last year, three of the present authors redeveloped and refined these ideas by combining the C*-algebraic approach to quantum theory with the so-called internal language of topos theory (Heunen et al. in arXiv:0709.4364). The goal of the present paper is to illustrate our abstract setup through the (...) concrete example of the C*-algebra M n (ℂ) of complex n×n matrices. This leads to an explicit expression for the pointfree quantum phase space Σ n and the associated logical structure and Gelfand transform of an n-level system. We also determine the pertinent non-probabilisitic state-proposition pairing (or valuation) and give a very natural topos-theoretic reformulation of the Kochen–Specker Theorem.In our approach, the nondistributive lattice ℘(M n (ℂ)) of projections in M n (ℂ) (which forms the basis of the traditional quantum logic of Birkhoff and von Neumann) is replaced by a specific distributive lattice $\mathcal{O}(\Sigma_{n})$ of functions from the poset $\mathcal{C}(M_{n}(\mathbb{C}))$ of all unital commutative C*-subalgebras C of M n (ℂ) to ℘(M n (ℂ)). The lattice $\mathcal{O}(\Sigma_{n})$ is essentially the (pointfree) topology of the quantum phase space Σ n , and as such defines a Heyting algebra. Each element of $\mathcal{O}(\Sigma_{n})$ corresponds to a “Bohrified” proposition, in the sense that to each classical context $C\in\mathcal{C}(M_{n}(\mathbb{C}))$ it associates a yes-no question (i.e. an element of the Boolean lattice ℘(C) of projections in C), rather than being a single projection as in standard quantum logic. Distributivity is recovered at the expense of the law of the excluded middle (Tertium Non Datur), whose demise is in our opinion to be welcomed, not just in intuitionistic logic in the spirit of Brouwer, but also in quantum logic in the spirit of von Neumann.

The theory of quantum mechanics has often been thought to show an affinity with logical empiricism: in both, observation plays a central role, and questions about what is unobservable are dismissed. However, there were also strong tensions between the logical empiricism of the Vienna Circle and implications drawn from quantum physics. In the 1920s and 1930s, many physicists thought that quantum mechanics revealed a limit to what could be known scientifically, and this opened the door to a wide range of (...) speculations, in which quantum mechanics was connected with free will, organic life, psychology, and religion—speculations in which many leading quantum physicists were engaged. Members of the Vienna Circle, such as Frank and Schlick, looked at quantum mechanics for a confirmation of their empiricist views, but they were at the same time critical about these wider implications drawn from quantum mechanics, which in their eyes were connected with broader mystical and irrational trends in society. They engaged in particular with the views of Bohr and Jordan, both of whom expressed a sympathy for logical empiricism while at the same time arguing for claims that proved hard to reconcile with the scientific world conception of the Vienna Circle.

BackgroundIn the Netherlands, Foundation De Einder offers counselling to people who wish to be able to self-determine the timing and manner of their end of life.AimThis study explores the experiences with counselling that counselees receive from counsellors facilitated by Foundation De Einder.MethodsOpen coding and inductive analysis of in-depth interviews with 17 counselees.ResultsCounselling ranged from solely receiving information about lethal medication to combining this with psychological counselling about matters of life and death, and the effects for close ones. Counselees appreciated the (...) availability of the counsellor, their careful and open attitude, feeling respected and being reminded about their own responsibility. Some counselees felt dependent on the counsellor, or questioned their competency. Most counselees collected lethal medication. This gave them peace of mind and increased their quality of life, but also led to new concerns. Few were inclined to use their self-collected medication. Counselling contributed to thinking about if, when and how counselees would like to end their life.ConclusionHaving obtained means to end their lives can offer people feelings of reassurance, which can increase their quality of life, but can also give rise to new concerns. Next to providing information on lethal medication, counsellors can play an important role by having an open non-judgemental attitude, providing trustworthy information and being available. These positively valued aspects of counselling are also relevant for physicians taking care of patients who wish to self-determine the timing and manner of their end of life. (shrink)

The principle of philosophy, Schelling declares in his 1810 Stuttgarter Privatvorlesungen, is the Absolute or God.1 The terms are brought into close yet ambiguous proximity by this assertion. Yet how are we to think them together? It is far from clear just how the Absolute—the abstract, universal, all-encompassing name Idealism gives to what, most fundamentally, there is—and God, a name with a rather longer life story, are to be related. Are we to take it that the Absolute and God are (...) to be baldly equated? That the one is a mere term of convenience properly understood in the light of the other? That the one is a supplement or corrective that the other is in need of? And who would be the arbiter of... (shrink)

In this essay, I argue that Søren Kierkegaard’s oeuvre can be seen as a theater of ideas. This argument is developed in three steps. First, I will briefly introduce a theoretical framework for addressing the theatrical dimension of Kierkegaard’s works. This framework is based on a distinction between“performative writing strategies” and “categories of performativity.” As a second step, I will focus on Repetition: A Venture in Experimenting Psychology, by Constantin Constantius, one of the best examples of Kierkegaard’s innovative way of (...) doing philosophy. This strange and elusive book introduces the difficult and counter-intuitive notion of repetition. Repetition is a category of performativity that aims to activate the subjectivity of the reader. This performative effect is achieved by confronting the reader with an “unresolved”existential problem that is not yet drawn into clarity but is staged in all its confusions and contradictions. Kierkegaard’s pseudonym Constantius relies here on a performative writing strategy that is animated by a dialectic of advance and withdrawal. In the last and third step, I will analyze Constantius’s own reflection on the performative dimension of his text. Constantius has left several clues behind, each of which suggests that he deliberately developed a performative writing strategy. (shrink)

A central intuition many epistemologists seem to have is that knowledge is distinctively valuable. In his paper 'Radical Scepticism, Epistemic Luck and Epistemic Value', Duncan Pritchard rejects the virtue-theoretic explanation of this intuition. This explanation says that knowledge is distinctively valuable because it is a cognitive achievement. It is maintained, in the first place, that the arguments Pritchard musters against the thesis that knowledge is a cognitive achievement are unconvincing. It is argued, in the second place, that even if the (...) arguments against the thesis that knowledge is a cognitive achievement were convincing, there is another explanation of the intuition that knowledge has final value available: the question-relative treatment of knowledge.

Privacy is valued by many. But what it means to have privacy remains less than clear. In this paper, I argue that the notion of privacy should be understood in epistemic terms. What it means to have (some degree of) privacy is that other persons do not stand in significant epistemic relations to those truths one wishes to keep private.

This article demonstrates a novel conceptualization of sublimity: the sublime in the pedestrian. This pedestrian mode of sublimity is exemplified by the Biblical Abraham, the central figure of Kierkegaard’s pseudonymous Fear and Trembling. It is rooted in the analysis of one of the foundational stories of the three monotheistic religions: Abraham’s averted sacrifice of his son Isaac. The defining feature of this new, pedestrian mode of sublimity is that is remains hidden behind what I call a total incognito. It is (...) similar to the classical ‘elevated mode of sublimity’ as developed by Burke, Kant, and Schiller insofar as it denotes two contrasting feelings at once: repulsion and attraction. It is different insofar as Kierkegaard’s pedestrian mode of sublimity remains hidden from view and can only be shown indirectly. This article expounds the new, pedestrian mode of sublimity by investigating the relation between the incognito and the sublime in Fear and Trembling. It achieves that goal by engaging three perspectives: (1) the sublime failure that comes to the fore in the incognitos of an imaginary Abraham; (2) the ‘fear without being afraid’ that is invoked by God’s incognitos; (3) the total incognito of the pedestrian which conceals Abraham’s sublimity.

We study behind-the-scenes investor activism promoting environmental, social, and governance improvements by means of a proprietary dataset of a large international, socially responsible activist fund. We examine the activist’s target selection, forms of engagement, impact on ESG performance, drivers of success, and effects on the targets’ operations and value creation. Target firms are typically large and visible, perform well, and have high liquidity and low ESG performance. Engagement induces ESG rating adjustments: firms with poor ex ante ESG ratings experience a (...) ratings increase after complying with the activist’s demands, whereas firms with high ex ante ESG ratings experience a ratings decrease following the revelation of their ESG problems. Activism that is focused on environmental and social issues is more likely to succeed if targets are ESG-sensitive. Successful engagements boost targets’ sales. Risk-adjusted excess stock returns of successful engagements outperform those of unsuccessful engagements by 2.7%. Results are especially strong for firms with low ex ante ESG scores. Specifically, targeted firms in the lowest ex ante ESG quartile outperform matched peers by 7.5% in the year after the end of the engagement. Our results thus suggest that the activism regarding corporate social responsibility generally improves ESG practices and corporate sales and is profitable to the activist. Taken together, we provide direct evidence that ethical investing and strong financial performance, both from the activist’s and the targeted firm’s perspective, can go hand-in-hand together.

Many philosophers are building a solid case in favour of the knowledge account of assertion (KAA). According to KAA, if one asserts that P one represents oneself as knowing that P. KAA has recently received support from linguistic data about prompting challenges, parenthetical positioning and predictions. In this article, I add another argument to this rapidly growing list: an argument from what I will call ‘reinforcing parenthesis’.

The goal of the present study was to investigate whether children’s cognitive strengths can compensate the accompanied weaknesses related to their specific learning difficulties. A Bayesian multigroup mediation SEM analysis in 281 fourth-grade children identified a cognitive compensatory mechanism in children with mathematical learning difficulties : Children with weak number sense, but strong rapid naming performed slightly better on mathematics compared to peers with weak rapid naming. In contrast, a compensatory mechanism was not identified for children with a comorbid mathematical (...) and reading difficulty. One explanation for the latter finding could relate to the lack of ability to compensate, because of the difficulties these children experience in both academic domains. These findings lead to a new direction in research on learning difficulties in mathematics and/or reading by suggesting that children with a learning disability each have a unique profile of interrelated cognitive strengths and weaknesses. Children might compensate with these strengths for their weaknesses, which could lead to learning gains in the affected domain. (shrink)

This study was designed to investigate the trust relationship between parents and teachers in first grade. Additional research questions were whether trust was related to ethnicity and reading performance. The five facets of trust; benevolence, reliability, competence, honesty and openness, were measured on a 4-point Likert scale. Reading performance was measured by the three-minute test. Parents were found to have more trust in the reliability, competence and honesty of teachers than teachers in parents. Native-Dutch and immigrant parents have the same (...) trust level towards their children?s teacher. However, teachers reported lower trust levels on all five facets of trust for immigrant parents. Our findings indicated that ethnicity has no influence on parents trust in teachers, but ethnicity may explain teachers? trust in parents. Some support was found for the assumption that teachers? trust plays a role in reading performance. Children were found to have higher reading performance when teachers reported higher trust in the benevolence and openness of parents. (shrink)

For Kierkegaard the ‘psychological experiment’ is a literary strategy. It enables him to dramatize an existential conflict in an experimental mode. Kierkegaard’s aim is to study the source of movement that animates the existing individual (this is the psychological part). However, he is not interested in the representation of historical individuals in actual situations, but in the construction of fictional characters that are placed in hypothetical situations; this allows him to set the categories in motion “in order to observe completely (...) undisturbed what these require” without caring to what extent someone has met this requirement or is able to meet it (this is the experimental part). -/- The ‘psychological experiment’ is a category of indirect communication that is developed most extensively by Frater Taciturnus, the pseudonymous author of the third part of Stages on Life’s Way. (I) Taciturnus introduces the psychological experiment as a new trajectory in modern literature that offers an alternative to poetry and speculative drama. He develops this new trajectory in praxis (in the novella ‘“Guilty?”/“Not Guilty?” A Story of Suffering: A Psychological Experiment by Frater Taciturnus’) as well as in theory (in the ‘Letter to the Reader’ that accompanies his novella). (II) Two other pseudonymous authors further enrich the conceptual field of the psychological experiment. Constantin Constantius develops the notion ‘experimenting psychology’; Johannes Climacus reflects on the reader’s contemporaneity with the character. (shrink)

The recent discovery of an indeterministic system in classical mechanics, the Norton dome, has shown that answering the question whether classical mechanics is deterministic can be a complicated matter. In this paper I show that indeterministic systems similar to the Norton dome were already known in the nineteenth century: I discuss four nineteenth century authors who wrote about such systems, namely Poisson, Duhamel, Boussinesq and Bertrand. However, I argue that their discussion of such systems was very different from the contemporary (...) discussion about the Norton dome, because physicists in the nineteenth century conceived of determinism in essentially different ways: whereas in the contemporary literature on determinism in classical physics, determinism is usually taken to be a property of the equations of physics, in the nineteenth century determinism was primarily taken to be a presupposition of theories in physics, and as such it was not necessarily affected by the possible existence of systems such as the Norton dome.
