In two experiments subjects attempted to identify words presented below the objective threshold using two task strategies emphasizing either allowing a word to pop into their heads or looking carefully at the stimulus field . Words were selected to represent both meaningful and structural dimensions. We also asked subjects to indicate their strategy preference and to rate their motivation to perform well. In the absence of conscious perception, both strategy preference and word meaning interacted with strategy condition, mediating the accuracy (...) of subjects′ direct word identification judgments. Motivation also mediated performance. Word structure had no effect. Unconscious perception manifested only in the pop condition, underscoring the importance of task strategy in determining whether subliminal effects are observed. A follow-up control experiment using sham flashes demonstrated that strategy preference and motivation effects were not artifacts resulting from performance feedback cues. (shrink)

Van Selst and Merikle argued that the critical Preference × Strategy interaction findings could be alternatively explained by positing individual differences as a function of preference and strategy. They further argued that ruling out conscious perception depends on making the exhaustiveness assumption. We argue that the inhibitory effects satisfy objective threshold criteria regardless of possible individual differences in thresholds. We further suggest that the inhibitory findings are inherently incompatible with the conscious perception explanation and that therefore we do not need (...) to make the exhaustiveness assumption. We thus stand by our original conclusion that subliminal perception at the objective threshold has been demonstrated. (shrink)

_Metaphysics: A Contemporary Introduction_ is for students who have already completed an introductory philosophy course and need a fresh look at the central topics in the core subject of metaphysics. It is essential reading for any student of the subject. This Fourth Edition is revised and updated and includes two new chapters on Parts and Wholes, and Metaphysical Indeterminacy or vagueness. This new edition also keeps the user-friendly format, the chapter overviews summarizing the main topics, concrete examples to clarify difficult (...) concepts, annotated further reading at the end of each chapter, endnotes, and a full bibliography. Topics addressed include: the problem of universals the nature of abstract entities the problem of individuation the nature of modality identity through time the nature of time the nature of parts and wholes the problem of metaphysical indeterminacy the Realism/anti-Realism debate. Wherever possible, Michael J. Loux and Thomas M. Crisp relate contemporary views to their classical sources in the history of philosophy. As experienced teachers of philosophy and important contributors to recent debates, Loux and Crisp are uniquely qualified to write this book. (shrink)

An emerging class of theories concerning the functional structure of the brain takes the reuse of neural circuitry for various cognitive purposes to be a central organizational principle. According to these theories, it is quite common for neural circuits established for one purpose to be exapted (exploited, recycled, redeployed) during evolution or normal development, and be put to different uses, often without losing their original functions. Neural reuse theories thus differ from the usual understanding of the role of neural plasticity (...) (which is, after all, a kind of reuse) in brain organization along the following lines: According to neural reuse, circuits can continue to acquire new uses after an initial or original function is established; the acquisition of new uses need not involve unusual circumstances such as injury or loss of established function; and the acquisition of a new use need not involve (much) local change to circuit structure (e.g., it might involve only the establishment of functional connections to new neural partners). Thus, neural reuse theories offer a distinct perspective on several topics of general interest, such as: the evolution and development of the brain, including (for instance) the evolutionary-developmental pathway supporting primate tool use and human language; the degree of modularity in brain organization; the degree of localization of cognitive function; and the cortical parcellation problem and the prospects (and proper methods to employ) for function to structure mapping. The idea also has some practical implications in the areas of rehabilitative medicine and machine interface design. (shrink)

Michael G. Titelbaum presents a new Bayesian framework for modeling rational degrees of belief—the first of its kind to represent rational requirements on agents who undergo certainty loss.

Machine learning algorithms pervade contemporary society. They are integral to social institutions, inform processes of governance, and animate the mundane technologies of daily life. Consistently, the outcomes of machine learning reflect, reproduce, and amplify structural inequalities. The field of fair machine learning has emerged in response, developing mathematical techniques that increase fairness based on anti-classification, classification parity, and calibration standards. In practice, these computational correctives invariably fall short, operating from an algorithmic idealism that does not, and cannot, address systemic, Intersectional (...) stratifications. Taking present fair machine learning methods as our point of departure, we suggest instead the notion and practice of algorithmic reparation. Rooted in theories of Intersectionality, reparative algorithms name, unmask, and undo allocative and representational harms as they materialize in sociotechnical form. We propose algorithmic reparation as a foundation for building, evaluating, adjusting, and when necessary, omitting and eradicating machine learning systems. (shrink)

To accept that cognition is embodied is to question many of the beliefs traditionally held by cognitive scientists. One key question regards the localization of cognitive faculties. Here we argue that for cognition to be embodied and sometimes embedded, means that the cognitive faculty cannot be localized in a brain area alone. We review recent research on neural reuse, the 1/f structure of human activity, tool use, group cognition, and social coordination dynamics that we believe demonstrates how the boundary between (...) the different areas of the brain, the brain and body, and the body and environment is not only blurred but indeterminate. In turn, we propose that cognition is supported by a nested structure of task-specific synergies, which are softly assembled from a variety of neural, bodily, and environmental components (including other individuals), and exhibit interaction dominant dynamics.

This paper contributes to our understanding of farm data value chains with assistance from 54 semi-structured interviews and field notes from participant observations. Methodologically, it includes individuals, such as farmers, who hold well-known positionalities within digital agriculture spaces—platforms that include precision farming techniques, farm equipment built on machine learning architecture and algorithms, and robotics—while also including less visible elements and practices. The actors interviewed and materialities and performances observed thus came from spaces and places inhabited by, for example, farmers, crop (...) scientists, statisticians, programmers, and senior leadership in firms located in the U.S. and Canada. The stability of “the” artifacts followed for this project proved challenging, which led to me rethinking how to approach the subject conceptually. The paper is animated by a posthumanist commitment, drawing heavily from assemblage thinking and critical data scholarship coming out of Science and Technology Studies. The argument’s understanding of “chains” therefore lies on an alternative conceptual plane relative to most commodity chain scholarship. To speak of a data value chain is to foreground an orchestrating set of relations among humans, non-humans, products, spaces, places, and practices. The paper’s principle contribution involves interrogating lock-in tendencies at different “points” along the digital farm platform assemblage while pushing for a varied understanding of governance depending on the roles of the actors and actants involved.

Drawing on a rich pragmatist tradition, this book offers an account of the different kinds of ‘oughts’, or varieties of normativity, that we are subject to contends that there is no conflict between normativity and the world as science describes it. The authors argue that normative claims aim to evaluate, to urge us to do or not do something, and to tell us how a state of affairs ought to be. These claims articulate forms of action-guidance that are different in (...) kind from descriptive claims, with a wholly distinct practical and expressive character. This account suggests that there are no normative facts, and so nothing that needs any troublesome shoehorning into a scientific account of the world. This work explains that nevertheless, normative claims are constrained by the world, and answerable to reason and argumentation, in a way that makes them truth-apt and objective. (shrink)

The concept that peope have of themselves as a 'person' is one of the most intimate notions that they hold. Yet the way in which the category of the person is conceived varies over time and space. In this volume, anthropologists, philosophers, and historians examine the notion of the person in different cultures, past and present. Taking as their starting point a lecture on the person as a category of the human mind, given by Marcel Mauss in 1938, the contributors (...) critically assess Mauss's speculation that ntions of the person, rather than being primarily philosophical or psychological, have a complex social and ideological origin. Discussing societies ranging from ancient Greece, India, and China to modern Africa and Papua New Guinea, they provide fascinating descriptions of how these different cultures define the person. But they also raise deeper theoretical issues: What is universally constant and what is culturally variable in people's thinking about the person? How can these variations be explained? Has there been a general progressive development toward the modern Western view of the person? What is distinctive about this? How do one's notions of the person inform one's ability to comprehend alternative formulations? These questions are of compelling interest for a wide range of anthropologists, philosophers, historians, psychologists, sociologists, orientalists, and classicists. The book will appeal to any reader concerned with understanding one of the most fundamental aspects of human existence. (shrink)

Kant believed that true enlightenment is the use of reason freely in public. This book systematicaaly traces the philosophical origins and development of the idea that the improvement of human understanding requires public activity. Michael Losonsky focuses on seventeenth-century discussions of the problem of irresolution and the closely connected theme of the role of volition in human belief formation. This involves a discussion of the work of Descartes, Hobbes, Locke, Spinoza and Leibniz. Challenging the traditional views of seventeenth-century philosophy (...) and written in a lucid, non-technical language, this book will be eagerly sought out by historians of philosophy and students of the history of ideas.

In “On duties to oneself,” Marcus G. Singer argued that, contrary to long established philosophical tradition, there are no duties to oneself. Singer observes that to have a duty is to be accountable to someone for that duty’s fulfillment, and while she to whom a duty is owed may release the person who has the duty from being bound to fulfill it, the latter cannot release herself from the duty. For releasing oneself from a duty is no different from simply (...) opting not to fulfill it, which would make the duty no more than a mere option and rob it of its categorical character. Singer thus argues that (a) A has a duty against herself; (b) if A has a duty against herself, then A is accountable to herself for the duty’s performance; (c) if A has a duty against herself, A can release herself from the duty; and (d) because a person is accountable to the individual owed the duty for its fulfillment, no one can release herself from an obligation, form an inconsistent set.

This article examines Kant′s use of the expression “fact of reason” by giving an analysis of the pseudo-mathematical method which Kant employs in the first part of the Critique of Practical Reason. It turns out that Kant′s use of this expression has nothing to do with appealing to a certain fact as being an obvious, self-evident truth. There is no need for such an appeal since the “Fundamental Law of Pure Practical Reason” is a “practical postulate” which, like a postulate (...) in geometry, is unquestionably certain. In order to realize its validity it is sufficient to know what a practical law is and on what its validity depends. The fundamental law of pure practical reason needs, in Kant′s view, a “deduction” since it is a synthetic principle a priori. But its deduction cannot be a proof since postulates neither can nor need be proved. It has to be a justification which guarantees that the use of pure reason in giving practical laws is not “transcendent”, but “immanent”. This justification has, unlike Kant′s deduction of the “Postulates of Empirical Thinking”, the systematic form of a “defence” which invalidates possible objections by showing that they themselves necessarily rest on a transcendent use of reason.

In this article we explore the different trajectories of this one drug, phenylbutazone, across two species, humans and horses in the period 1950–2000. The essay begins by following the introduction of the drug into human medicine in the early 1950s. It promised to be a less costly alternative to cortisone, one of the “wonder drugs” of the era, in the treatment of rheumatic conditions. Both drugs appeared to offer symptomatic relief rather than a cure, and did so with the risk (...) of side effects, which with phenylbutazone were potentially so severe that it was eventually banned from human use, for all but a few diseases, in the early 1980s. Phenylbutazone had been used with other animals for many years without the same issues, but in the 1980s its uses in veterinary medicine, especially in horses, came under increased scrutiny, but for quite different reasons. The focus was primarily the equity, economics, and ethics of competition in equine sports, with differences in cross-species biology and medicine playing a secondary role. The story of phenylbutazone, a single drug, shows how the different biologies and social roles of its human/animal subjects resulted in very different and changing uses. While the drug had a seemingly common impact on pain and inflammation, there were inter-species differences in the drug’s metabolism, the conditions treated, dosages, and, crucially, in intended clinical outcomes and perceptions of its benefits and risks.

Motivational internalism (MI) holds that, necessarily, if an agent judges that she is morally obligated to ø, then, that agent is, to at least some minimal extent, motivated to ø. Opponents of MI sometimes invoke depression as a counterexample on the grounds that depressed individuals appear to sincerely affirm moral judgments but are ‘listless’ and unmotivated by such judgments. Such listlessness is a credible counterexample to MI, I argue, only if the actual clinical disorder of depression, rather than a merely (...) hypothetical example of such listlessness, is the source of this listlessness. However, empirical evidence concerning depression shows that, to the extent that the depressed are motivationally listless at all, they are abnormally listless only with respect to an important class of non-moral judgments, namely, their prudential normative judgments (i.e., those concerning their own happiness and well-being), not their moral judgments. Hence, depressed individuals do not constitute a counterexample to MI. This conclusion has important methodological implications concerning how supporters and opponents of MI can best defend their respective theses. (shrink)

Chagnon’s analysis of a well-known axe fight in the Yanomamö village of Mishimishiböwei-teri (Chagnon and Bugos 1979) is among the earliest empirical tests of kin selection theory for explaining cooperation in humans. Kin selection theory describes how cooperation can be organized around genetic kinship and is a fundamental tool for understanding cooperation within family groups. Previous analysis on groups of cooperative Lamaleran whale hunters suggests that the role of genetic kinship as a principle for organizing cooperative human groups could be (...) less important in certain cases than previously thought (Alvard Human Nature 14:129–163, 2003b). Evidence that supports a strong role for genetic kinship—groups are found to be more related than expected by chance—may be spurious because of the correlation between social structure and genetic kinship. Reanalysis of Chagnon’s data using matrix regression techniques, however, confirms that genetic kinship was the primary organizing principle in the axe fight; affinal relations were also important, whereas lineage identity explained nothing.

Recognizing the potential hidden artistic contributions of persons with dementia opens new opportunities for interpretation and potential communication. This visual essay explores the authors’ responses to the fragile objects of art produced by a person with severe dementia and examines what may be learned from them.

The metatethical position known as motive internalism (MI) holds that moral beliefs are necessarily motivating. Adina Roskies (in Philosophical Psychology, 16) has recently argued against MI by citing patients with injuries to the ventromedial (VM) cortex as counterexamples to MI. Roskies claims that not only do these patients not act in accordance with their professed moral beliefs, they exhibit no physiological or affective evidence of being motivated by these beliefs. I argue that Roskies' attempt to falsify MI is unpersuasive because (...) the evidence used to attribute the relevant moral beliefs to VM patients is insufficient: Contra Roskies, that VM patients are proficient moral reasoners does not establish the presence of these moral beliefs. In addition, the linguistic evidence Roskies cites (a) is vulnerable to methodological worries about its reliability or authenticity, (b) does not override counterevidence derived from the patients' nonlinguistic behavior, and (c) is undermined by VM patients' inability to correctly attribute moral beliefs to others. I conclude with a proposal about how MI should be interpreted, given that it is not falsified by empirical evidence of the sort put forth by Roskies. (shrink)

“The physics of representation” aims to define the word “representation” as used in the neurosciences, argue that such representations as described in neuroscience are related to and usefully illuminated by the representations generated by modern neural networks, and establish that these entities are “representations in good standing”. We suggest that Poldrack succeeds in, exposes some tensions between the broad use of the term in neuroscience and the narrower class of entities that he identifies in the end, and between the meaning (...) of “representation” in neuroscience and in psychology in, and fails in. This results in some hard choices: give up on the broad scope of the term in neuroscience or continue to embrace the broad, psychologically inflected sense of the term, and deny the entities generated by neural nets are representations in the relevant sense.

That there was a ‘Bacteriological Revolution’ in medicine in the late nineteenth-century, associated with the development of germ theories of disease, is widely assumed by historians; however, the notion has not been defined, discussed or defended. In this article a characterisation is offered in terms of four linked rapid and radical changes: a series of discoveries of the specific causal agents of infectious diseases and the introduction of Koch’s Postulates; a reductionist and contagionist turn in medical knowledge and practice; greater (...) authority for experimental laboratory methods in medicine; the introduction and success of immunological products. These features are then tested against developments in four important but previously neglected diseases: syphilis, leprosy, gonorrhoea and rabies. From these case-studies I conclude that the case for a Bacteriological Revolution in late nineteenth-century medicine in Britain remains unproven. I suggest that historians have read into the 1880s changes that occurred over a much longer period, and that while there were significant shifts in ideas and practices over the decade, the balance of continuities and changes was quite uneven across medicine. My argument is only for Britain; in other countries the rate and extent of change may have been different. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ghazali and Demonstrative Science MICHAEL E. MARMURA I MEDIEVALISLA_MICtheologians subjected Aristotle's theory of the essential efficient cause to severe criticism and rejected it. This criticism and rejection finds its most forceful expression in the writings of Ghazali (al-Ghaz~li) (d. 1111).1 In his Tahafut al-Falasifa (The Incoherence of the Philosophers), he argues on logical and empirical grounds that the alleged necessary connection between what is habitually regarded as the (...) natural efficient cause and its effect cannot be proven. He does not, however, take an agnostic stand on this question but proceeds to affirm two points: (1) that there is no causal agency in natural things; (2) that all natural events are the direct creation of God. Ghazali, moreover, does not confine such divine action to the realm of the inanimate and the irrational, in his al-Iqtis.~d fi-l-Ftiqad (The Golden Mean of Belief), he affirms the doctrine that the individual human act, like any other occurrence in the world, is also the direct creation of God. Causal efficacy resides in God alone. But the divine act, for Ghazali, is not an essential act. It does not proceed as the necessary consequence of divine essence. It is the arbitrary decree of the divine will, an attribute coeternal, but not identical with divine essence. Ghazali thus denies essential action altogether. In all this, he gives expression to the occasionalism of the Islamic school of dogmatic theology (kal~m) to which he belonged, the Ashcarite school. Ghazali had also a keen interest in logic. He wrote logical treatises for his fellow theologians, encouraging them to master this art as a tool to rebutt their doctrinal opponents. The~ treatises, in the main, sum up and explain the logic used by the Islamic philosophers--a logic that reflects the Stoic and Aristotelian traditions. Ghazali recognizes formal logic to be philosophically neutral, and hence in no way conflicting with his theology." He does not confine himself to formal logic in these expositions, however, but discusses Aristotelian demonstration. And it is in his statements on demonstration that we seem to be confronted with paradox. Demonstrative science, as understood by the Islamic philosophers, rests on the theory of essential causes and functions in terms of it. Indeed, in his reply to Ghazali's rejection of essential efficient causes in nature, Averroes (Ibn Rushd) (d. 1198) argues Texts frequently referred to in the notes will be abbreviated as follows: Demonstration: Ibn Sin~, Al-Shifa~; Logic V.; Demonstration, ed.

We would have no true knowledge; at best, only opinion. 3For this staunch defender of Aristotle, the theory of natural efficient causality constitutes a necessary condition for demonstrative science. Yet Ghazali in his writings does not deny the claim that demonstration gives us certain knowledge about the natural order. On the contrary, he seems to be affirming this in both his Tahdfutand the logical treatise he appended to this work, Mi~jdral-CIlm(The Standardfor Knowledge).If Ghazali does in fact uphold this claim for demonstration, then he must either deny that the theory of essential efficient causality is a necessary condition for demonstrative science, or fall into contradiction. At first glance, Ghazali's position in the Micy~r,where he gives his most comprehensive treatment of demonstration, is highly ambiguous and suggests contradiction. He seems for the most part to be reproducing the essentials of the Aristotelian demonstrative theory. Although in one section he reaffirms his rejection of necessary causal connection in nature, he nonetheless continues to use such terms as "cause," "effect," "necessity" and "certainty" in what appear to be...

If a brain is uploaded into a computer, will consciousness continue in digital form or will it end forever when the brain is destroyed? Philosophers have long debated such dilemmas and classify them as questions about personal identity. There are currently three main theories of personal identity: biological, psychological, and closest continuer theories. None of these theories can successfully address the questions posed by the possibility of uploading. I will argue that uploading requires us to adopt a new theory of (...) identity, psychological branching identity. Psychological branching identity states that consciousness will continue as long as there is continuity in psychological structure. What differentiates this from psychological identity is that it allows identity to continue in multiple selves. According to branching identity, continuity of consciousness will continue in both the original brain and the upload after nondestructive uploading. Branching identity can also resolve long standing questions about split-brain syndrome and can provide clear predictions about identity in even the most difficult cases imagined by philosophers.

The various jurisdictions worldwide that now legally permit assisted suicide (or voluntary euthanasia) vary concerning the medical conditions needed to be legally eligible for assisted suicide. Some jurisdictions require that an individual be suffering from an unbearable and futile medical condition that cannot be alleviated. Others require that individuals must be suffering from a terminal illness that will result in death within a specified timeframe, such as six months. -/- Popular and academic discourse about assisted suicide paradigmatically focuses on individuals (...) with ‘physical,’ i.e., non-psychiatric medical conditions, such as cancer or AIDS. Here I defend analyses of the notions of unbearable suffering, futility, and terminality that imply that, regardless of which of these medical conditions is invoked, at least some individuals with severe and persistent psychiatric illnesses satisfy these conditions and ought to be classified as legally eligible for assisted suicide. The legal and moral case for a right to assisted suicide is therefore not in principle weaker for the severely psychiatrically disordered than for those with ‘typical’ terminal or futile medical conditions.

One of the most foundational and continually contested questions in the cognitive sciences is the degree to which the functional organization of the brain can be understood as modular. In its classic formulation, a module was defined as a cognitive sub-system with nine specific properties; the classic module is, among other things, domain specific, encapsulated, and implemented in dedicated neural substrates. Most of the examinations—and especially the criticisms—of the modularity thesis have focused on these properties individually, for instance by finding (...) counterexamples in which otherwise good candidates for cognitive modules are shown to lack domain specificity or encapsulation. The current paper goes beyond the usual approach by asking what some of the broad architectural implications of the modularity thesis might be, and attempting to test for these. The evidence does not favor a modular architecture for the cortex. Moreover, the evidence suggests that best way to approach the understanding of cognition is not by analyzing and modelling different functional domains in isolation from the others, but rather by looking for points of overlap in their neural implementations, and exploiting these to guide the analysis and decomposition of the functions in question. This has significant implications for the question of how to approach the design and implementation of intelligent artifacts in general, and language-using robots in particular. (shrink)

Assertions of statements such as 'it's raining, but I don't believe it' are standard examples of what is known as Moore's paradox. Here I consider moral equivalents of such statements, statements wherein individuals affirm moral judgments while also expressing motivational indifference to those judgments. I argue for four main conclusions concerning such statements: 1. Such statements are genuinely paradoxical, even if not contradictory. 2. This paradoxicality can be traced to a form of epistemic self-defeat that also explains the paradoxicality of (...) ordinary Moore-paradoxical statements. 3. Although a simple form of internalism about moral judgment and motivation can explain the paradoxicality of these moral equivalents, a more plausible explanation can be provided that does not rely on this simple form of internalism. 4. The paradoxicality of such statements suggests a more credible understanding of the thesis that those who are not motivated by their moral judgments are irrational. (shrink)

An important application of ultrafilters is in the ultraproduct construction in model theory. In this paper we study ultraproducts of countable structures, whose universe we assume is ω , using ultrafilters on a countable index set, which we also assume to be ω . Many of the properties of the ultraproduct are in fact inherent properties of the ultrafilter. For example, if we take a sequence of countable linear orders without maximal element, then their ultraproduct will have no maximal element, (...) and we can ask what its cofinality is. This cardinal depends only on the ultrafilter; it does not depend on what linear orders comprise the factors. (shrink)

Rips et al. claim that the principles underlying the structure of natural numbers cannot be inferred from interactions with the physical world.

This paper is a critical assessment of argumentum ad baculum, or appeal to force. Its principal contention is that, contrary to common opinion, there is no general fallacy of ad baculum. Most real-life ad baculums are, in fact, fairly strong. A basic logical form for reconstructed ad baculums is proposed, and a number of heterodoxical conclusions are also advanced and argued for. They include that ad baculum is not necessarily a prudential argument, that ad baculum need not involve force, violence, (...) or threats, and that one can argue ad baculum to oneself. The starting point of the paper, however, is a critical evaluation of three ad baculums from the exercise sets of Irving Copi's well-known Introduction to Logic. (shrink)

Dementia is more than a disease. What dementia is, how it is understood, and how it is experienced is influenced by multiple factors including our societal preoccupation with individual identity. This essay introduces empirical and theoretical evidence of alternative ways of understanding dementia that act as a challenge to common assumptions. It proposes that dementia be understood as an experience of systems, particularly networks of people affected by the diagnosis. Taking this step reveals much about the dementia experience, and about (...) what can be learned from persons with dementia and their networks of family, friends, and carers. It also suggests that dementia may be best thought of as an ecology that arises from the interaction between neuropathological change, people, language, and meaning. While challenging, this perspective may provide new ways of responding to dementia and caring for those affected by it. (shrink)

Legal statutes prohibiting felons from voting result in nearly 4 million Americans, disproportionately African-American and male, being unable to vote. These felony disenfranchisement (FD) statutes have a long history and apparently enjoy broad public support. Here I argue that despite the popularity and extensive history of these laws, denying felons the right to vote is an unjust form of punishment in a democratic state. FD serves none of the recognized purposes of punishment and may even exacerbate crime. My strategy is (...) not to argue for this conclusion directly. Rather, I consider seven arguments for the moral legitimacy of FD, each of which will be found lacking. My emphasis falls not on the legal or constitutional questions associated with FD, but with its moral justification within a broadly liberal political framework. These arguments draw upon a variety of philosophical outlooks; three justify FD by appealing to justice or desert, three others justify FD based on its allegedly beneficial social consequences, and a final argument is a hybrid of both sorts of considerations. Not only do all these arguments fail, but eliminating FD could have salutary effects on our present climate of political discourse. -/- . (shrink)

David Boonin has recently argued that although no existing theory of legal punishment provides adequate moral justification for the practice of punishing criminal wrongdoing, compulsory victim restitution (CVR) is a morally justified response to such wrongdoing. Here I argue that Boonin’s thesis is false because CVR is a form of punishment. I first support this claim with an argument that Boonin’s denial that CVR is a form of punishment requires a groundless distinction between a state’s response to a criminal offense (...) and its response to an offender’s failure to comply with the sanctions imposed for that offense. I then suggest that this argument points to a definition of punishment that not only meets Boonin’s own desiderata for a definition of punishment but also implies that CVR is a form of punishment. Finally, I argue that CVR is a form of punishment even under Boonin’s own proposed definition of punishment. -/- . (shrink)
