Both left libertarians, who support the redistribution of income and wealth through taxation, and right libertarians, who oppose redistributive taxation, share an important view: that, looming catastrophes aside, the state must never redistribute any part of our body or our person without our consent. Cécile Fabre rejects that view. For her, just as the undeservedly poor have a just claim to money from their fellow citizens in order to lead a minimally flourishing life, the undeservedly ‘medically poor’ have a just (...) claim to help from fellow citizens in order to lead such a life. Such obligatory help may in principle involve even the supply of body parts for transplantation. The state ought to exact such resources from the medically rich whenever doing so would secure the prospect of a minimally flourishing life to the medically poor without denying that prospect to anyone else. Fabre criticizes Ronald Dworkin's belief in ‘a prophylactic line that comes close to making the body inviolate, that is, making body parts not parts of social resources at all’. For her, ‘Duties to help. . . do not stop at material resources: they involve the body. . . in invasive ways’. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.4 (2002) 555-575 [Access article in PDF] Measurer of All Things:John Greaves (1602-1652), the Great Pyramid, and Early Modern Metrology Zur Shalev [Figures]Writing from Istanbul to Peter Turner, one of his colleagues at Merton College, Oxford, John Greaves was deeply worried: Onley I wonder that in so long time since I left England I should neither have received my brasse quadrant which (...) I left to be finished for my journey thither, nor any notice of it [...]. I agreed with mr. Allen upon price and the time that he should finish it, if he hath failed me he hath done me the greatest injury that can be. 1A great injury indeed, because Greaves's journey to Italy and the Levant was all about measuring—luckily the instrument did reach him at some later stage. The thirty-six-year-old Professor of Geometry at Gresham College was taking the measurements of countless monuments and objects in the locations he visited. In Rome he measured, among many other ancient structures, Cestius' Pyramid and St. Peter's basilica. In Lucca, deeply impressed, he counted his paces around the beautiful city walls. In Siena he observed together with a "Mathematical Professor" one of the Sidera Medicea using "a glass." In Egypt he even hurt his eyes gazing at the sun, looking for sunspots and measuring its diameter. 2 His measuring mission, however, culminated in the fixing of the [End Page 555] latitudes of Istanbul, Rhodes, and Alexandria. As Bishop Juxton wrote before the trip to Greaves's employers at Gresham College (apparently using Greaves's own promotional language): This worke I find by the best astronomers, especially by Ticho Brache [ sic ] and Kepler, hath beene much desired as tending to the advancement of that science, and I hope it wil be an honour to that nation and prove ours if we first observe it. 3A mathematician-Orientalist, commanding the ancient and modern astronomical and geographical literature of Latin, Greek, Hebrew, Arabic, and Persian authors, Greaves was arguably the best qualified European at the period to perform the task. That he miscalculated the latitude of Rhodes is of less consequence for his present-day readers. 4 However, one of the most obscure and therefore telling of his measurement activities was the survey of the Pyramids of Giza, which resulted in the Pyramidographia (1646). 5 This remarkable learned treatise and travel account hybrid, which is at the focus of the present study, gives us a glimpse into the rich and complex world of scientific antiquarians.Greaves is most conveniently remembered today as an Orientalist. While we must be thankful to Edward Said for broadening the meaning of Orient-alism—from an academic discipline, accumulating objective knowledge of the East, into a much wider cultural discourse, his emphasis on the nineteenth and twentieth centuries and on the European colonial mindset is less useful for making historical sense of what early modern Orientalists were doing—physically and culturally. We can understand Greaves's "Oriental" enterprise in its [End Page 556] depth and variety only within long established European traditions of scholarship and keeping the intellectual concerns of his time in mind. 6But beyond articulating for us the nature of early Orientalism, the Pyramidographia, as well as Greaves's entire scientific career, situated in their wider European context, provide a fine entry point into a foreign world of learned practices and methods. It teaches us how well into the seventeenth century astronomy and philology, observation and bookishness, could coalesce in one figure, in one enterprise. 7 We still lack a modern biography of Greaves, a complex protagonist of a complex period, and even a full evaluation of his intellectual work. While this paper surely cannot compensate for that, I do attempt here a brief exposition of Greaves's Pyramidographia. 8Modern historians of archaeology and Egyptology, preoccupied mostly with the disciplines' progress and development of scientific standards, have noted the Pyramidographia in passing and praised its precise language and rigorous research...

Dreams are a remarkable experiment in psychology and neuroscience, conducted every night in every sleeping person. They show that the human brain, disconnected from the environment, can generate an entire world of conscious experiences by itself. Content analysis and developmental studies have promoted understanding of dream phenomenology. In parallel, brain lesion studies, functional imaging and neurophysiology have advanced current knowledge of the neural basis of dreaming. It is now possible to start integrating these two strands of research to address fundamental (...) questions that dreams pose for cognitive neuroscience: how conscious experiences in sleep relate to underlying brain activity; why the dreamer is largely disconnected from the environment; and whether dreaming is more closely related to mental imagery or to perception.

This paper deals with the question: how is computation best individuated? -/- 1. The semantic view of computation: computation is best individuated by its semantic properties. 2. The causal view of computation: computation is best individuated by its causal properties. 3. The functional view of computation: computation is best individuated by its functional properties. -/- Some scientific theories explain the capacities of brains by appealing to computations that they supposedly perform. The reason for that is usually that computation is individuated (...) semantically. I criticize the reasons in support of this view and its presupposition of representation and semantics. Furthermore, I argue that the only justified appeal to a representational individuation of computation might be that it is partly individuated by implicit intrinsic representations. (shrink)

The question ‘What is computation?’ might seem a trivial one to many, but this is far from being in consensus in philosophy of mind, cognitive science and even in physics. The lack of consensus leads to some interesting, yet contentious, claims, such as that cognition or even the universe is computational. Some have argued, though, that computation is a subjective phenomenon: whether or not a physical system is computational, and if so, which computation it performs, is entirely a matter of (...) an observer choosing to view it as such. According to one view, which we dub bold anti-realist pancomputationalism, every physical object (can be said to) computes every computer program. According to another, more modest view, some computational systems can be ascribed multiple computational descriptions. We argue that the first view is misguided, and that the second view need not entail observer-relativity of computation. At least to a large extent, computation is an objective phenomenon. Construed as a form of information processing, we argue that information-processing considerations determine what type of computation takes place in physical systems. (shrink)

Brain implants, such as Deep Brain Stimulation (DBS), which are designed to improve motor, mood and behavioural pathology, present unique challenges to our understanding of identity, agency and free will. This is because these devices can have visible effects on persons' physical and psychological properties yet are essentially undetectable when operating correctly. They can supplement and compensate for one's inherent abilities and faculties when they are compromised by neuropsychiatric disorders. Further, unlike talk therapy or pharmacological treatments, patients need not ‘do’ (...) anything for the treatment to take effect. If one accepts, as we argue here, that brain implants are unique among implantable types of devices, then this can have significant implications for what it means to persist as the same person and be the source of one's thoughts and actions. By examining two of the most common indications for DBS in current use, namely in the motor (Parkinson's Disease) and psychiatric (Major Depression) domains, we further argue that although DBS, as it is currently applied, does not necessarily represent a unique threat to personal identity and agency per se, it introduces an unprecedented ‘third party’ into the debate on these concepts. In this way, DBS can be used as a tool to begin probing, both conceptually and empirically, some of philosophy's most perennial metaphysical questions. (shrink)

This article analyses and interprets the works of Friedensreich Hundertwasser (1928–2000) as a source of inspiration for environmental ethics and offers an extended model of the Ecological Self based on an interpretation of his works. Hundertwasser was a prominent Jewish-Austrian artist and environmental activist, yet despite his commitment to environmental issues, he has not received the attention he deserves from the environmental ethics community. His works and writings suggest a critique and reformulation of the well-known concept of the Ecological Self. (...) This concept implies that humans are essentially embedded in the natural world – that the Self is porous and open rather than disengaged and atomistic. This article suggests an alternative, holistic and extended version of this concept. It assesses and incorporates additional layers found between humans and nature – clothing, architecture, urban environments, and social and political environments. (shrink)

The article begins by reconstructing the just distribution of the social bases of self-respect, a principle of justice that is covert in Rawls’s writing. I argue that, for Rawls, justice mandates that each social basis for self-respect be equalized. Curiously, for Rawls, that principle ranks higher than Rawls’s two more famous principles of justice - equal liberty and the difference principle. I then recall Rawls’s well-known confusion between self-respect and another form of self-appraisal, namely, confidence in one’s determinate plans and (...) capacities. Correcting that confusion forces Rawls to accept objectionable and illiberal politics. Surprisingly, a consistent Rawls must endorse absolute economic equality, deny liberty any priority whatsoever, or sponsor still other illiberal political views - evidence of a flaw in the ethical basis of Rawls’s politics.

Floridi’s Theory of Strongly Semantic Information posits the Veridicality Thesis. One motivation is that it can serve as a foundation for information-based epistemology being an alternative to the tripartite theory of knowledge. However, the Veridicality thesis is false, if ‘information’ is to play an explanatory role in human cognition. Another motivation is avoiding the so-called Bar-Hillel/Carnap paradox. But this paradox only seems paradoxical, if ‘information’ and ‘informativeness’ are synonymous, logic is a theory of inference, or validity suffices for rational inference; (...) a, b, and c are false.

It is proved that for every positive integer n, the number of non-Tukey-equivalent directed sets of cardinality $\leq \aleph _n$ is at least $c_{n+2}$, the $(n+2)$ -Catalan number. Moreover, the class $\mathcal D_{\aleph _n}$ of directed sets of cardinality $\leq \aleph _n$ contains an isomorphic copy of the poset of Dyck $(n+2)$ -paths. Furthermore, we give a complete description whether two successive elements in the copy contain another directed set in between or not.

The phenomenon of digital computation is explained (often differently) in computer science, computer engineering and more broadly in cognitive science. Although the semantics and implications of malfunctions have received attention in the philosophy of biology and philosophy of technology, errors in computational systems remain of interest only to computer science. Miscomputation has not gotten the philosophical attention it deserves. Our paper fills this gap by offering a taxonomy of miscomputations. This taxonomy is underpinned by a conceptual analysis of the design (...) and implementation of conventional computational systems at various levels of abstraction. It shows that ‘malfunction’ as it is typically used in the philosophy of artefacts only represents one type of miscomputation. (shrink)

Growing interest in psychiatric neurosurgery, and in deep brain stimulation (DBS) in particular, requires that the field be placed in the appropriate historical and scientific context. Current methods of neuromodulation for refractory psychiatric conditions are premised on assumptions similar to those proposed in earlier attempts, namely, the number of resistant patients and the absence of any other effective treatments. As a result, a discussion of the current and future prospects, as well as the limits, of neuromodulation is required to avoid (...) a replay of earlier transgressions, and to place its current chapter in the appropriate historical and ethical context.

Gillian Hadfield and Stephen Macedo argue that late-Rawlsian stability for the right reasons, that is, stability based on participants’ reciprocal cooperation, can arise even if participants start out only economically rational and indifferent to justice. As they explain, even purely rational actors have an interest in having a neutral “shared logic” to coordinate decentralized enforcement of social cooperation and in internalizing that logic. Once developed and internalized, they add, that logic renders their reasoning public, and their persons, reasonable and responsive (...) to Rawlsian justice considerations. Hadfield and Macedo’s account seeks to lend Rawlsian contractualism a contractarian foundation. I raise five challenges to their account, focusing on the sense in which actors “start out” purely rational; on illiberal means that may serve rational citizens’ joint ends; on the counterexample of Martin Luther King; on the difficulty of specifying the mechanism for shared logic-internalization; and on the further counterexample of a medical student who internalizes compassion, only upon the condition that it serves his rational aims.

This is a retrospective of surrogacy in Israel in the context of medically assisted reproduction. The practice of surrogacy emerged in the 1980s, suggesting a radical view of women as autonomous reproductive agents free from double standards of patriarchy. In 1995 Israel enacted a law that regulated domestic surrogacy for the benefit of infertile married women in accord with orthodox views of halakha. In recent years we see the growth of inter-country practices catering to otherwise ineligible intended parents, and a (...) demand for posthumous male reproduction. Meanwhile, women become objects of intrusive medical procedures and commodities of a global market, more often than not for the benefit of others rather than themselves. Yet the essence of human reproduction remains relational, and calls for care and responsibility. (shrink)

One defining feature of the Hindu religious worldviews is a belief in the impermanence of the body and its perception as a source of suffering due to a misguided attachment of the self to its corporeal manifestation. This view is expressed in several important traditions, including classical yoga, which perceives the physical body as an impediment to attaining liberation and irrelevant in the state of liberation.However, the perception of the physical body in liberation is going through ontological changes in early (...) medieval Haṭhayoga texts. The dichotomy between embodied and disembodied states of the body when one is liberated is the focus of this article. In several medieval yoga texts dating between the eleventh and the fifteenth centuries, the ontological immortal state of living liberation is more similar to physical death. Often the exact text holds both views of embodied and disembodied states simultaneously with no overt inconsistency. I argue that these tensions and contradictions can be explained in two ways: by looking at the assessed timeline of the texts and by reflecting on their sectarian and social origin. (shrink)

Which notion of computation (if any) is essential for explaining cognition? Five answers to this question are discussed in the paper. (1) The classicist answer: symbolic (digital) computation is required for explaining cognition; (2) The broad digital computationalist answer: digital computation broadly construed is required for explaining cognition; (3) The connectionist answer: sub-symbolic computation is required for explaining cognition; (4) The computational neuroscientist answer: neural computation (that, strictly, is neither digital nor analogue) is required for explaining cognition; (5) The extreme (...) dynamicist answer: computation is not required for explaining cognition. The first four answers are only accurate to a first approximation. But the “devil” is in the details. The last answer cashes in on the parenthetical “if any” in the question above. The classicist argues that cognition is symbolic computation. But digital computationalism need not be equated with classicism. Indeed, computationalism can, in principle, range from digital (and analogue) computationalism through (the weaker thesis of) generic computationalism to (the even weaker thesis of) digital (or analogue) pancomputationalism. Connectionism, which has traditionally been criticised by classicists for being non-computational, can be plausibly construed as being either analogue or digital computationalism (depending on the type of connectionist networks used). Computational neuroscience invokes the notion of neural computation that may (possibly) be interpreted as a sui generis type of computation. The extreme dynamicist argues that the time has come for a post-computational cognitive science. This paper is an attempt to shed some light on this debate by examining various conceptions and misconceptions of (particularly digital) computation. (shrink)

This essay responds to criticisms of and reflections on A Theory of Truces offered by Keith Breen, David Lyons, Colleen Murphy and Thaddeus Metz. I focus on the place of truces within just war theory, the permissibility of making truces with particularly unsavory actors, the tension between present and future considerations in truce making, and Truce Thinking as an instance of non-ideal theory.

It is common in cognitive science to equate computation (and in particular digital computation) with information processing. Yet, it is hard to find a comprehensive explicit account of concrete digital computation in information processing terms. An information processing account seems like a natural candidate to explain digital computation. But when ‘information’ comes under scrutiny, this account becomes a less obvious candidate. Four interpretations of information are examined here as the basis for an information processing account of digital computation, namely Shannon (...) information, algorithmic information, factual information and instructional information. I argue that any plausible account of concrete computation has to be capable of explaining at least the three key algorithmic notions of input, output and procedures. Whist algorithmic information fares better than Shannon information, the most plausible candidate for an information processing account is instructional information. (shrink)

There are many different notions of information in logic, epistemology, psychology, biology and cognitive science, which are employed differently in each discipline, often with little overlap. Since our interest here is in biological processes and organisms, we develop a taxonomy of functional information that extends the standard cue/signal distinction (in animal communication theory). Three general, main claims are advanced here. (1) This new taxonomy can be useful in describing learning and communication. (2) It avoids some problems that the natural/non-natural information (...) distinction faces. (3) Functional information is​ ​produced through exploration and stabilisation processes. (shrink)

Is the mathematical function being computed by a given physical system determined by the system’s dynamics? This question is at the heart of the indeterminacy of computation phenomenon (Fresco et al. [unpublished]). A paradigmatic example is a conventional electrical AND-gate that is often said to compute conjunction, but it can just as well be used to compute disjunction. Despite the pervasiveness of this phenomenon in physical computational systems, it has been discussed in the philosophical literature only indirectly, mostly with reference (...) to the debate over realism about physical computation and computationalism. A welcome exception is Dewhurst’s ([2018]) recent analysis of computational individuation under the mechanistic framework. He rejects the idea of appealing to semantic properties for determining the computational identity of a physical system. But Dewhurst seems to be too quick to pay the price of giving up the notion of computational equivalence. We aim to show that the mechanist need not pay this price. The mechanistic framework can, in principle, preserve the idea of computational equivalence even between two different enough kinds of physical systems, say, electrical and hydraulic ones. (shrink)

The notion of the riddle plays a pivotal role in Wittgenstein’s Tractatus . By examining the comparisons he draws between philosophical problems and riddles, this paper offers a reassessment of the aims and methods of the book. Solving an ordinary riddle does not consist in learning a new fact; what it requires is that we transform the way we use words. Similarly, Wittgenstein proposes to transform the way philosophers understand the nature of their problems. But since he holds that these (...) problems are ultimately unsolvable, rather than attempting to solve the riddles of philosophy, he aims to dissolve them. (shrink)

Recent developments in the field of neurosurgery, specifically those dealing with the modification of mood and affect as part of psychiatric disease, have led some researchers to discuss the ethical implications of surgery to alter personality and personal identity. As knowledge and technology advance, discussions of surgery to alter undesirable traits, or possibly the enhancement of normal traits, will play an increasingly larger role in the ethical literature. So far, identity and enhancement have yet to be explored in a neurosurgical (...) context, despite the fact that 1) neurological disease and treatment both potentially alter identity, and 2) that neurosurgeons will likely be the purveyors of future enhancement implantable technology. Here, we use interviews with neurosurgical patients to shed light on the ethical issues and challenges that surround identity and enhancement in neurosurgery. The results provide insight into how patients approach their identity prior to potentially identity-altering procedures and what future ethical challenges lay ahead for clinicians and researchers in the field of neurotherapeutics.

When a group of doctors and nurses from Boston, Massachusetts, provided evaluation and heart surgery to children in Ghana, they encountered three rationing dilemmas: (1) What portion of surgery slots should they reserve for the simplest, most cost-effective surgeries? (2) How much time should be reserved for especially simple, nonsurgical interventions? (3) How much time should be reserved to training local staff to perform such surgeries? This article investigates these three dilemmas.

Judeo-Christian Western culture recognizes a legislating, judging and punishing God. The view that a judge separate from man indeed exists, constitutes, among other things, cultural motivation for the pursuit of success, on the one hand, and fear of failure, guilt, on the other. The human-being fears the consequences of judgement, especially those entailing punishment, and attempts with all his might to succeed in the eyes of the judge. This study‟s underlying assumption is that judge-ment constitutes a deep structure in Western (...) culture and that its religious origins are in the culture‟s Jewish and Christian sources. Although religious judgement under-goes processes of secularization throughout the culture‟s history, it remains a deep cultural construct; while worldviews are deeply embedded in the religious expe-rience, as Jung contends, they have a latent capacity for preservation in the secular experience. A genealogical methodology will be applied to examine the con-cept of judgement. While genealogy deals with the past, its aim is to understand and critique the present reality. The genealogy will scrutinize the Jewish judgement, the Catholic judgement and the Calvinist judgement, while calling attention to their similarities and differences. (shrink)

In this paper I investigate responses to sentence (“yes-no”) questions in Greek dialogue which are neither a clear-cut ‘yes’ nor a ‘no’. I describe, classify, and discuss a range of patterns for expressing this strategy of indirectness, beginning with an example termed μέση ἀπόκρισις in the commentary of Olympiodorus to Plato Gorgias. Ancient rhetorical sources also discuss strategies for evading clear-cut non-polar responses to sentence questions in sections on the notion of ἀπόκρισις (and ἐρώτησις) without a fixed terminology. The fabricated (...) and quoted examples which these ancient sources give, serve as a point of departure for my classification of patterns in occurrences collected from literary dialogues (selections from Plato, and a corpus study of the Greek comedies of Aristophanes and Menander). The analysis of mechanisms for these non-polar responses draws on philological as well as linguistic scholarship from Greek antiquity through contemporary dialogue analysis, and refers also to contexts and conventions of characterization in Ancient Greek sources.

Advances in neuromodulation and an improved understanding of the anatomy and circuitry of psychopathology have led to a resurgence of interest in surgery for psychiatric disease. Clinical trials exploring deep brain stimulation (DBS), a focally targeted, adjustable and reversible form of neurosurgery, are being developed to address the use of this technology in highly selected patient populations. Psychiatric patients deemed eligible for surgical intervention, such as DBS, typically meet stringent inclusion criteria, including demonstrated severity, chronicity and a failure of conventional (...) therapy. Although a humanitarian device exemption by the US Food and Drug Administration exists for its use in obsessive-compulsive disorder, DBS remains a largely experimental treatment in the psychiatric context, with its use currently limited to clinical trials and investigative studies. The combination of a patient population at the limits of conventional therapy and a novel technology in a new indication poses interesting challenges to the informed consent process as it relates to clinical trial enrollment. These challenges can be divided into those that relate to the patient, their disease and the technology, with each illustrating how traditional conceptualisations of research consent may be inadequate in the surgical psychiatry context. With specific reference to risk analysis, patient autonomy, voluntariness and the duty of the clinician-researcher, this paper will discuss the unique challenges that clinical trials of surgery for refractory psychiatric disease present to the consent process. Recommendations are also made for an ethical approach to clinical trial consent acquisition in this unique patient population. (shrink)

This article argues that, in its standard formulation, luck-egalitarianism is false. In particular, I show that disadvantages that result from perfectly free choice can constitute egalitarian injustice. I also propose a modified formulation of luck-egalitarianism that would withstand my criticism. One merit of the modification is that it helps us to reconcile widespread intuitions about distributive justice with equally widespread intuitions about punitive justice.

In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental theory regarding its phenomenal aspect. There is an “explanatory gap” between our scientific knowledge of functional consciousness and its “subjective,” phenomenal aspects, referred to as the “hard problem” of consciousness. The phenomenal aspect of consciousness is the first-person answer to “what it’s like” question, and it (...) has thus far proved recalcitrant to direct scientific investigation. Naturalistic dualists argue that it is composed of a primitive, private, non-reductive element of reality that is independent from the functional and physical aspects of consciousness. Illusionists, on the other hand, argue that it is merely a cognitive illusion, and that all that exists are ultimately physical, non-phenomenal properties. We contend that both the dualist and illusionist positions are flawed because they tacitly assume consciousness to be an absolute property that doesn’t depend on the observer. We develop a conceptual and a mathematical argument for a relativistic theory of consciousness in which a system either has or doesn’t have phenomenal consciousness with respect to some observer. Phenomenal consciousness is neither private nor delusional, just relativistic. In the frame of reference of the cognitive system, it will be observable and in other frame of reference it will not. These two cognitive frames of reference are both correct, just as in the case of an observer that claims to be at rest while another will claim that the observer has constant velocity. Given that consciousness is a relativistic phenomenon, neither observer position can be privileged, as they both describe the same underlying reality. Based on relativistic phenomena in physics we developed a mathematical formalization for consciousness which bridges the explanatory gap and dissolves the hard problem. Given that the first-person cognitive frame of reference also offers legitimate observations on consciousness, we conclude by arguing that philosophers can usefully contribute to the science of consciousness by collaborating with neuroscientists to explore the neural basis of phenomenal structures.

Do the dynamics of a physical system determine what function the system computes? Except in special cases, the answer is no: it is often indeterminate what function a given physical system computes. Accordingly, care should be taken when the question ‘What does a particular neuronal system do?’ is answered by hypothesising that the system computes a particular function. The phenomenon of the indeterminacy of computation has important implications for the development of computational explanations of biological systems. Additionally, the phenomenon lends (...) some support to the idea that a single neuronal structure may perform multiple cognitive functions, each subserved by a different computation. We provide an overarching conceptual framework in order to further the philosophical debate on the nature of computational indeterminacy and computational explanation. (shrink)

The fundamental error of the metaphysical tradition, according to Heidegger, is the subordination of general ontology to the ontology of a special, exemplary entity (God, the soul, etc.). But Being and Time itself treats one kind of entity as exemplary, namely Dasein. Does this mean that Heidegger fails to free himself from the kind of metaphysics that he sought to criticize? To show how he avoids this charge I propose to examine the parallels between the methodology of Being and Time (...) and the methodology Heidegger ascribes to Aristotle's Metaphysics. Heidegger takes the virtue of Aristotle's inquiry to reside in the way he resists the subordination of general to special ontology: Aristotle was guided by a "double concept" of metaphysics, pursued two irreducibly distinct methods of inquiry, and avoided the temptation to unite them. In proposing to similarly pursue a "double task" in Being and Time Heidegger seeks to apply this insight to his own work. Alongside the task of fundamental ontology, Heidegger spells out the shape of a second task, Destruktion, understood as a historical critique that traces ontological concepts back to their ontic roots. But Destruktion is not a mere addendum to fundamental ontology; the two tasks are meant to counterbalance one another and thereby prevent the collapse of the ontological difference between being and beings. Indeed, Heidegger proposes to apply Destruktion to the results of his own fundamental ontology. He hopes to thereby achieve a transformation of the philosophical attitude which underpins the metaphysical tradition. (shrink)

Artefacts do not always do what they are supposed to, due to a variety of reasons, including manufacturing problems, poor maintenance, and normal wear-and-tear. Since software is an artefact, it should be subject to malfunctioning in the same sense in which other artefacts can malfunction. Yet, whether software is on a par with other artefacts when it comes to malfunctioning crucially depends on the abstraction used in the analysis. We distinguish between “negative” and “positive” notions of malfunction. A negative malfunction, (...) or dysfunction, occurs when an artefact token either does not or cannot do what it is supposed to. A positive malfunction, or misfunction, occurs when an artefact token may do what is supposed to but, at least occasionally, it also yields some unintended and undesirable effects. We argue that software, understood as type, may misfunction in some limited sense, but cannot dysfunction. Accordingly, one should distinguish software from other technical artefacts, in view of their design that makes dysfunction impossible for the former, while possible for the latter. (shrink)

This chapter investigates how a reading of Wittgenstein along the lines laid out by Cora Diamond makes room for a novel approach to ethical truth. Following Diamond, I develop the connection between the kinds of elucidatory propositions by means of which we spell out and maintain the shape of our theoretical thinking, such as “‘someone’ is not the name of someone” and “five plus seven equals twelve,” and the kind of propositions by means of which we spell out and maintain (...) the shape of ethical thinking, such as “slavery is unjust.” As Diamond points out in connection with the last example, this is a proposition that we take to be an undeniable truth; for anyone who would attempt to negate it would become unintelligible to us. In this sense this ethical truth spells out the limits of ethical thinking. And yet what counts as coherent thought about such matters tends to shift over time. Indeed the great difficulty of overcoming ethical disagreements has to do with the fact that what is at stake in them is not just the content, but the form and limits of thought. Nonetheless, Diamond proposes that ethical propositions may count as genuine truths. For this to make sense, a middle path between realism and relativism must be found. In order to show how this is possible, and in order to defend Diamond’s view, I propose to approach ethical truth by means of a disjunctivist strategy. On this approach, while we, just as much as our interlocutor, may at times be misled in our ethical thinking, and while we may at times fail to shape our ethical thought in ways that prevent us from gaining clarity on ethical matters, this does not detract from the fact that we may at times be right, and that we may then genuinely possess ethical truth.
