Like Aristotle’s texts, the present volume consists of logoi, lecture notes Heidegger left behind which later in his life he considered for possible inclusion in his Gesamtausgabe. Omissions in the manuscript amounting to about eleven pages were made good by referring to two transcripts of what was heard, respectively, by Walter Bröcker and Helene Weiss, two of Heidegger’s students at Freiburg University in the summer of 1923, when the course was given. Here and there in the manuscript, Heidegger provided headings (...) for sections of the text and for a number of inserts and supplements added later. The detailed section and subsection headings, which are an outline of the course, were added by the German editor, Käte Bröcker-Oltmanns. According to the translator, by Heidegger’s own admission, the text comprises “the first notes for Being and Time”, and therein lies one element of our interest in these logoi, the other being the possibility that “Ontology—The Hermeneutics of Facticity” was “the original form of Heidegger’s ‘original ethics’”.

There is, it is claimed, a long-standing link between photography and the realist novel. Nancy Armstrong in particular argues that the pictorial veridicality of literary realism is at least partly premised upon the rapid propagation of photographic images through late 19th century culture. In doing so, Armstrong argues that photography and realist fiction were mutual participants in an epistemological project wherein the horizons of the ‘real world’—at least within the context of literary fiction—were continuously and unconsciously drawn and redrawn. Meanwhile, (...) within the context of science and technology history, it is often taken for granted that late 19th century science photographers assumed that photographs provided direct, untrammelled access to an entirely different notion of the real: a real unviolated by the messy business of human perception and agency. While this notion is a gross misrepresentation of the facts of the matter, this is not to imply that late 19th century science photographs were ‘fictive’, at least in the sense intended by Armstrong, Novak, Helen Groth, and others. Although it might be the case that non-scientific applications of photography in the late 19th century were conducted in a fictive register, science photography proves a rather more challenging case. In the wake of this observation, this chapter first demarcates and define these conflicting notions of realism, in which I will demonstrate that the epistemic commitments of literary and metaphysical realism (specifically Cartesian realism) are categorically incompatible, though they share a common intuition. Subsequently, I then explain the value of photography to scientific practitioners by appealing to the formal properties of photographs. Third, I argue that although photographic processes guarantee that photographs are traces of the world, there is no further guarantee that those traces will be isomorphic to experience; whilst 19th century science photographs were undeniably visions of the world, they are parts of the world hitherto unseen by human eyes. Finally, I contend that science photography in the late 19th century anticipated key developments in philosophical realism—not least the transition from 18th and 19th century Cartesian realism to 20th century scientific realism. By revealing an invisible universe entirely unlike the one of our phenomenological experience, late 19th century science photography helped reintroduce humanity to a world in which we lack ontological rank or priority.

New methods to analyse social media data provide a powerful way to know publics and capture what they say and do. At the same time, access to these methods is uneven, with corporations and governments tending to have best access to relevant data and analytics tools. Critics raise a number of concerns about the implications dominant uses of data mining and analytics may have for the public: they result in less privacy, more surveillance and social discrimination, and they provide new (...) ways of controlling how publics come to be represented and so understood. In this paper, we consider if a different relationship between the public and data mining might be established, one in which publics might be said to have greater agency and reflexivity vis-à-vis data power. Drawing on growing calls for alternative data regimes and practices, we argue that to enable this different relationship, data mining and analytics need to be democratised in three ways: they should be subject to greater public supervision and regulation, available and accessible to all, and used to create not simply known but reflexive, active and knowing publics. We therefore imagine conditions in which data mining is not just used as a way to know publics, but can become a means for publics to know themselves. (shrink)

This 1999 book demonstrates a method for reading the texts of Aristotle by revealing a continuous line of argument running from the Physics to De Caelo. The author analyses a group of arguments that are almost always treated in isolation from one another, and reveals their elegance and coherence. She concludes by asking why these arguments remain interesting even though we now believe they are absolutely wrong and have been replaced by better ones. The book establishes the case that we (...) must rethink our approach to Aristotle's physical science and Aristotelian texts, and as such will provoke debate and stimulate new thinking amongst philosophers, classicists, and historians of science.

This paper argues that public statues of persons typically express a positive evaluative attitude towards the subject. It also argues that states have duties to repudiate their own historical wrongdoing, and to condemn other people’s serious wrongdoing. Both duties are incompatible with retaining public statues of people who perpetrated serious rights violations. Hence, a person’s being a serious rights violator is a sufficient condition for a state’s having a duty to remove a public statue of that person. I argue that (...) this applies no less in the case of the ‘morally ambiguous’ wrongdoer, who both accomplishes significant goods and perpetrates serious rights violations. The duty to remove a statue is a defeasible duty: like most duties, it can be defeated by lesser-evil considerations. If removing a statue would, for example, spark a violent riot that would risk unjust harm to lots of people, the duty to remove could be outweighed by the duty not to foreseeably cause unjust harm. This would provide a lesser-evil justification for keeping the statue. But it matters that the duty to remove is outweighed, rather than negated, by these consequences. Unlike when a duty is negated, one still owes something in cases of outweighing. And it especially matters that it is outweighed by the predicted consequences of wrongful behaviour by others.

Global ignorance about Africa continues to sustain inappropriate global interventions to resolve public health crises, often with disastrous consequences. To explain why this continues to happen, I marshal two theorems that predict basic statistical properties, called ‘the doctrinal paradox’ and ‘the discursive dilemma’, which underlie scientific consensus formation and evidence-based decision making on a global scale. These mathematical results illuminate the epistemic and material injustices committed by the protocols of medical research conducted at the highest level of global knowledge production (...) in the service of international humanitarian aid for Africans. These social choice theorems reveal that a global scientific consensus projecting claims and proposing policies about Africa’s disease burden is likely to yield a low degree of reliability, in that the probability of its accuracy is less than chance. The solution to this anomaly is to remove from the global scientific agenda the statistically unrealisable demand of satisfying too many multinational corporate and foreign governments’ priorities as equally entitled to benefit from the knowledge produced to improve Africa’s public health sector. Instead, foreign funding targeted to support medical science and policy in Africa should be directed by those specialists in situ who are most familiar with their own national health challenges and potential solutions, rather than relying upon foreign decision makers to interpret Africa’s emergency public health care needs.

Recently several thought experiments have been developed (by John Carroll amongst others) which have been alleged to refute the Ramsey-Lewis view of laws of nature. The paper aims to show that two such thought experiments fail to establish that the Ramsey-Lewis view is false, since they presuppose a conception of laws of nature that is radically at odds with the Humean conception of laws embodied by the Ramsey-Lewis view. In particular, the thought experiments presuppose that laws of nature govern the (...) behavior of objects. The paper argues that the claim that laws govern should not be regarded as a conceptual truth, and shows how the governing conception of laws manifests itself in the thought experiments. Hence the thought experiments do not constitute genuine counter-examples to the Ramsey-Lewis view. since the Humean is free to reject the conception of laws which the thought experiments presuppose.

In this paper Beebee argues that the problem of induction, which she describes as a genuine sceptical problem, is the same for Humeans than for Necessitarians. Neither scientific essentialists nor Armstrong can solve the problem of induction by appealing to IBE, for both arguments take an illicit inductive step.

This volume will be the starting point for future discussion and research.

Humean compatibilism is the combination of a Humean position on laws of nature and the thesis that free will is compatible with determinism. This article's aim is to situate Humean compatibilism in the current debate among libertarians, traditional compatibilists, and semicompatibilists about free will. We argue that a Humean about laws can hold that there is a sense in which the laws of nature are 'up to us' and hence that the leading style of argument for incompatibilism?the consequence argument?has a (...) false premiss. We also display some striking similarities between Humean compatibilism and libertarianism, an incompatibilist view. For example, standard libertarians face a problem about luck, and we show that Humean compatibilists face a very similar problem. (shrink)

Causation is a central topic in many areas of philosophy. In metaphysics, philosophers want to know what causation is, and how it is related to laws of nature, probability, action, and freedom of the will. In epistemology, philosophers investigate how causal claims can be inferred from statistical data, and how causation is related to perception, knowledge and explanation. In the philosophy of mind, philosophers want to know whether and how the mind can be said to have causal efficacy, and in (...) ethics, whether there is a moral distinction between acts and omissions and whether the moral value of an act can be judged according to its consequences. And causation is a contested concept in other fields of enquiry, such as biology, physics, and the law. This book provides an in-depth and comprehensive overview of these and other topics, as well as the history of the causation debate from the ancient Greeks to the logical empiricists. The chapters provide surveys of contemporary debates, while often also advancing novel and controversial claims; and each includes a comprehensive bibliography and suggestions for further reading. The book is thus the most comprehensive source of information about causation currently available, and will be invaluable for upper-level undergraduates through to professional philosophers.

The proposal of anything like a feminist epistemology has, I think, two sources. Feminist scholars have demonstrated how the scientific cards have been stacked against women for centuries. Given that the sciences are taken as the epitome of knowledge and rationality in modern Western societies, the game looks desperate unless some ways of knowing different from those that have validated misogyny and gynephobia can be found. Can we know the world without hating ourselves? This is one of the questions at (...) the core of discussions of feminist epistemology. It has spinoffs, e.g., can we know the world in ways that will permit women as well as men to thrive? Can we know the world without hating any human group? and so on. Now, these questions might be answered in a way that does not require any rethinking of fundamental philosophical issues. Some philosophers might argue that sexism in the sciences from Aristotle to human sociobiology results from a masculinist blinding that impedes the normal workings of the human cognitive apparatus. Unblinded, that apparatus produces real knowledge rather than ideology. Or: that was then, this is now. This somewhat overestimates the progress made in the sciences in the last 20 years, but can be read as a promissory note. (shrink)

The paper argues that it is possible for an incompatibilist to accept John Martin Fischer's plausible insistence that the question whether we are morally responsible agents ought not to depend on whether the laws of physics turn out to be deterministic or merely probabilistic. The incompatibilist should do so by rejecting the fundamentalism which entails that the question whether determinism is true is a question merely about the nature of the basic physical laws. It is argued that this is a (...) better option for ensuring the irrelevance of physics than the embrace of semi-compatibilism, since there are reasons for supposing that alternate possibilities are necessary for moral responsibility, despite Fischer's claims to the contrary. There are two distinct reasons for supposing that alternate possibilities might be necessary for moral responsibility—one of which is to do with fairness, the other to do with agency itself. It is suggested that if one focuses on the second of these reasons, Fischer's arguments for supposing that alternate possibilities are unnecessary for moral responsibility can be met by the incompatibilist. Some possible reasons for denying that alternate possibilities are necessary for the existence of agency are then raised and rejected. (shrink)

Is it possible to donate unpaired vital organs, foreseeing but not intending one's own death? We argue that this is indeed psychologically possible, and thus far agree with Charles Camosy and Joseph Vukov in their recent paper on 'double effect donation.' Where we disagree with these authors is that we see double effect donation not as a morally praiseworthy act akin to martyrdom but as a morally impermissible act that necessarily disrespects human bodily integrity. Respect for bodily integrity goes beyond (...) avoiding the aim to kill: not all side effects of deliberate bodily interventions can be outweighed by intended benefits for another even if the subject fully consents. It is not any necessary intention to kill or harm another or oneself that makes lethal donation/harvesting illicit but the more immediate intention to accept or perform surgery on an (innocent) person combined with the foresight of lethal harm and no health-related good for him or her. Double effect donation falls foul of the first condition of double effect reasoning in that the immediate act is wrong in itself. We argue further that the wider effects of such donation would be socially disastrous and corrupting of the medical profession: doctors should retain a sense of nonnegotiable respect for bodily integrity even when they intervene on willing subjects for the benefit of others.

Hume is traditionally credited with inventing the ‘regularity theory’ of causation, according to which the causal relation between two events consists merely in the fact that events of the first kind are always followed by events of the second kind. Hume is also traditionally credited with two other, hugely influential positions: the view that the world appears to us as a world of unconnected events, and inductive scepticism: the view that the ‘problem of induction’, the problem of providing a justification (...) for inference from observed to unobserved regularities, is insoluble. Hume on Causation is the first major work dedicated to Hume’s views on causation in over fifteen years, and it argues that Hume does not subscribe to any of these three views. It places Hume’s interest in causation within the context of his theory of the mind and his theory of causal reasoning, arguing that Hume’s conception of causation derives from his conception of the nature of the inference from causes to effects.

The paper considers whether psychiatric kinds can be natural kinds and concludes that they can. This depends, however, on a particular conception of ‘natural kind’. We briefly describe and reject two standard accounts – what we call the ‘stipulative account’ (according to which apparently a priori criteria, such as the possession of intrinsic essences, are laid down for natural kindhood) and the ‘Kripkean account’ (according to which the natural kinds are just those kinds that obey Kripkean semantics). We then rehearse (...) a more permissive account: Richard Boyd’s ‘homeostatic property cluster’ (HPC) account. We argue that psychiatric kinds can in principle count as natural kinds on the HPC account. Moreover, specific psychiatric kinds (Tourette’s, schizophrenia, etc.) can be natural kinds even if the category psychiatric disorder is not itself a natural kind. (shrink)

According to ‘regularity theories’ of causation, the obtaining of causal relations depends on no more than the obtaining of certain kinds of regularity. Regularity theorists are thus anti-realists about necessary connections in nature. Regularity theories of one form or another have constituted the dominant view in analytic Philosophy for a long time, but have recently come in for some robust criticism, notably from Galen Strawson. Strawson’s criticisms are natural criticisms to make, but have not so far provoked much response from (...) regularity theorists. The paper considers and rebuts Strawson’s objections. For example, Strawson claims that if there were no necessary connections in nature, we ought continually to find the regularity of the Universe surprising. I argue that the fact that the Universe is regular is something we take ourselves (fallibly) to know, and hence, in the light of this knowledge, its continued orderliness is not at all surprising. -/- .

Making a Difference presents fifteen original essays on causation and counterfactuals by an international team of experts. Collectively, they represent the state of the art on these topics. The essays in this volume are inspired by the life and work of Peter Menzies, who made a difference in the lives of students, colleagues, and friends. Topics covered include: the semantics of counterfactuals, agency theories of causation, the context-sensitivity of causal claims, structural equation models, mechanisms, mental causation, causal exclusion argument, free (...) will, and the consequence argument.

This paper defends a substance-based metaphysics for organisms against three arguments for thinking that we should replace a substantial understanding of living things with a processual one, which are offered by Dan Nicholson and John Dupré in their edited collection, Everything Flows: Towards a Processual Philosophy of Biology. Dupré and Nicholson consider three main empirical motivations for the adoption of a process ontology in biology. These motivations are alleged to stem from facts concerning metabolism; the life cycles of organisms; and (...) ecological interdependence. The paper discusses each of the three arguments in turn and concludes that none gives us any compelling reason to abandon the metaphysics of things. At best, they are arguments against a kind of caricature substance metaphysics that ought never to have been in the running in any case. Then, at the end of the paper, it is suggested that there may be more positive arguments for insisting on retaining things in our metaphysics, arguments which, perhaps ironically get their main impetus from the phenomenon of life.

Essentialism--roughly, the view that natural kinds have discrete essences, generating truths that are necessary but knowable only _a posteriori_--is an increasingly popular view in the metaphysics of science. At the same time, philosophers of language have been subjecting Kripke’s views about the existence and scope of the necessary _a posteriori_ to rigorous analysis and criticism. Essentialists typically appeal to Kripkean semantics to motivate their radical extension of the realm of the necessary _a posteriori_; but they rarely attempt to provide any (...) semantic arguments for this extension, or engage with the critical work being done by philosophers of language. This collection brings authors on both sides together in one volume, thus helping the reader to see the connections between views in philosophy of language on the one hand and the metaphysics of science on the other. The result is a book that will have a significant impact on the debate about essentialism, encouraging essentialists to engage with debates about the semantic presuppositions that underpin their position, and, encouraging philosophers of language to engage with the metaphysical presuppositions enshrined in Kripkean semantics.

This paper explores the relationship between a person's claim right not to be harmed and the duties this claim confers on others. I argue that we should reject Jonathan Quong's evidence-based account of this relationship, which holds that an agent A's possession of a claim against B is partly determined by whether it would be reasonable for A to demand B's compliance with a correlative duty. When B's evidence is that demanding compliance would not be reasonable, A cannot have a (...) claim against B. I suggest that some of the putatively problematic cases that Quong identifies can be resolved by plausibly narrowing the scope of the right not to be harmed. I also argue that Quong's view leads to implausible conclusions, and that his account of what happens to A's claim in the face of lesser-evil justifications is inconsistent with his broader view. I then defend the view that agents are required, and not merely permitted, to act on lesser-evil justifications. I further argue that A may not defend herself against the infliction of harms that are justified on lesser-evil grounds. However, she may defend herself in cases where B is only evidentially, and not objectively, justified in harming her. (shrink)

According to common-sense morality, agents can become morally connected to the wrongdoing of others, such that they incur special obligations to prevent or rectify the wrongs committed by the primary wrongdoer. We argue that, under certain conditions, voluntary and unjustified observation of another agent’s degrading wrongdoing, or of the ‘product’ of their wrongdoing, can render an agent morally liable to bear costs for the sake of the victim of the primary wrong. We develop our account with particular reference to widespread (...) modern phenomena such as so-called ‘revenge porn’, ‘up-skirting’, and the online observation of sexual assault and murder. On our account, observation is not a sui generis basis of liability. Instead, observation grounds liability in virtue of manifesting three, more general, grounds of liability. First, observation can compound a primary wrong, making that wrong more harmful for the victim. Second, observation can constitute degrading treatment of the victim. Third, in certain cases observation can enable primary wrongdoing. We conclude by discussing the conditions under which observing degrading wrongs might be morally justified. (shrink)

It is shown here that injustices due to racial discrimination are best identified in light of the deleterious effects they have upon their victims, rather than the beliefs and attitudes of their perpetrators. For among participants who cooperate clandestinely to bring about racial injustice there may be broad disagreement about what it is they are doing collectively, and why; or they may disagree in principle about whether what they are doing is morally right. I employ the notion of ‘nomotropic’ behaviour (...) to replace the oversimplified notion of ‘rule-following’ in order to explain how duplicity and hypocrisy fall shy of being regarded as irrational in social climates where implicit norms reinforce racial privileging while explicit norms denounce it. Further, examining the ‘collective utility’ of dogmatic beliefs and norms comprising part of the social architecture that covertly reinforces racial injustice may help to explain why it often seems to make so little diffe...

The role of the ‘ideal’ in political philosophy is currently much discussed. These debates cast useful light on Mill's self-designation as ‘under the general designation of Socialist’. Considering Mill's assessment of potential property-relations on the grounds of their desirability, feasibility and ‘accessibility’ (disambiguated as ‘immediate-availability’, ‘eventual-availability’ and ‘conceivable-availability’) shows us not only how desirable and feasible he thought ‘utopian’ socialist schemes were, but which options we should implement. This, coupled with Mill's belief that a socialist ideal should guide social reforms (...) (as the North Star guides mariners), reveals much more clearly the extent of his socialist commitments (even if he thought political economists would be concerned with forms of individual property for some time to come). Moreover, this framework for assessments of ‘ideal’ institutions makes a useful contribution to an ongoing contemporary debate. (shrink)

The evidence suggests that employers discriminate against ex-offenders in the labour market. The problem is potentially serious as it involves a substantial proportion of the population, especially the male population. Since research has shown that most people with prior convictions stop offending by their late 20s or early 30s, the validity of selection based on criminal record remains questionable. This paper examines the need for legal protection of ex-offenders by limiting employers' access to, and use of, information on criminal background. (...) The rights and interests of the various parties involved, employers, ex-offenders, and the general public, are discussed. Approaches to the legal protection of ex-offenders in Australia are reviewed and legislative changes proposed. (shrink)

This paper draws on the author's work in social epistemology and on comparative studies of sciences of human behavior to draw attention to the importance of interaction. Drawing further on recent and contemporary research in biology, she argues that interaction ought to be considered a distinct ontological category, not reducible to properties of its participants.

This paper begins with the problem of natural substance and its identification by Aristotle as the combination of form and matter, as distinct from the substrate of the body. This is an investigation of the relation between the combination of form and matter on the one hand and body on the other. Looking at both natural science and metaphysics will give us a clear account of the partners involved in the relationship that defines living things. That is the first step (...) toward understanding how and why they enter into a relation and exactly what, for Aristotle, is entailed by that relation. Being clear on the relation of natural substance in the sense of the combination of form and matter, soul and body, will in turn allow us to ask if soul is in every regard attached to body or if there is “something proper” to soul alone.

This essay offers a critique of the controversial proposal that peculiarities in African thought concerning time have a negative impact upon African economic development. The proposal under scrutiny takes the form of two corollaries whose notoriety dates back to John S. Mbiti’s (1969) infamous claim that African cultures lack an indigenous concept of the distant future. It is shown that these joint hypotheses appear to be either self-refuting or false. In consequence, the proposal that a cross-cultural scrutiny of time will (...) reveal defective concepts is reconsidered. It is proposed that deficiencies in the perception of time that bear a negative impact upon African economics are instead the cache of foreign experts who fail to appreciate conventional uses of time in Africa as rational strategies for risk avoidance, damage control, for resisting hegemonic authority, quelling foreign expropriation of African resources, and for maximizing efficiency given scarce capital and inadequate infrastructure. What begins as a deflationary dismissal of a long-standing debate over African indigenous thoughts about time concludes with a promising speculation about African idiosyncratic practices of time-management that are instrumental in negotiating the vicissitudes of spiralling underdevelopment.

This contribution explores correctives to several errors that Thomas Nagel seems to presuppose in his seminal defence of scepticism about global justice. I rely on lessons learned and conventions surviving in West African contemporary social and moral contexts, where people engage as a matter of course in divergent, historically antagonistic cultural and political traditions. On this view, global justice is a work in progress—not a fixed univocal formula but an on-going collaborative effort, a project in perpetual renovation and inter-cultural reconsideration (...) by successive generations which presupposes a diversity of values and ways of sanctifying human life. I consider ways in which an ethics of care, as suggested by Virginia Held, might have been anticipated by the time-honoured norms of governance and political culture surviving in complex African polities, cultures which have withstood the corrosion of external colonialism since early modernity. How might iconically African, universally fundamental moral notions of decency and fairness find their way back into the global marketplace of diplomatic discourse and economic policy design?To demonstrate the need to navigate towards some consensus within the diversity of indigenous concepts associated with justice and good governance in Africa, I discuss the fiasco displayed in a widely celebrated proposal for exercising globally principles of justice in the Western liberal political tradition applied to remedy Africans’ notorious resource curse.

The multi-purpose of publicizing a scientific consensus includes a communicative strategy by which scientific institutions accommodate the weighty social and economic demands to demonstrate they are collaborating and cooperating with non-scientific sectors of society, relying on a wide range of spokespeople and representatives to carry out the delivery of their consensus in formal, institutionally arranged, professional and impersonal public settings. I investigate the conditions and presuppositions that make it possible for a research consortium to contribute indirectly to public discourse beyond (...) the presentation of empirical data and theoretical speculations routinely associated with knowledge-producing collectives. The baptismal action of researchers in selecting a designative name to announce a new discovery of virus species and species variants does not follow the rigorous regulations that standardize all names of taxonomic categories in other biological sciences as well as higher order taxa in virology. It is argued here that the lack of clarity in the denotation of the term ‘Ebola’ (in epidemiological reports from West Africa throughout 2014–2016) serves the purpose of shifting a receptor’s understanding of a statement from its explicit assertive point to an implicit declarative, commissive, directive or expressive, covertly delivered point. Specialists of nomenclature concerned with quality assurance regard this lapse in standardization as a consequence of human fallibility demanding urgent intervention. Here it is proposed instead that the occlusive effect of a technical descriptive name may serve an important communicative function. (shrink)
