Mary Shepherd's An Essay upon the Relation of Cause and Effect, first published in 1824, was a pioneering work in metaphysics and epistemology. Together with her 1827 Essays on the Perception of an External Universe, they make her one of the most important philosophers of her era. Although widely neglected by the history of philosophy in the decades after her death, her works have recently begun to attract the attention and sustained study they deserve. In the course of (...) her writings, Shepherd offers trenchant and detailed rebuttals of the arguments and conclusions of many prominent predecessors-including George Berkeley, Thomas Reid, Dugald Stewart, Thomas Brown, William Lawrence, and especially David Hume-but she is no merely negative thinker. On the contrary, her critiques are always in the service of her own distinctive and highly original doctrines, which are of striking contemporary interest. Appearing two hundred years after its original publication, this is the first full modern edition of her first book, which presents and defends the theory of causation and scientific knowledge that constitutes the cornerstone of her entire philosophy. The edition includes an extensive introduction and scholarly notes throughout that provide historical and philosophical context while explaining the central ideas of the work. It also includes Shepherd's two essays published in 1828 and all of her known letters-all but one of them published here for the first time-which shed significant additional light on her philosophical ideas.

This is the first modern edition of the works of Lady Mary Shepherd, one of the most important women philosophers of the early modern period. Shepherd has been widely neglected in the history of philosophy, but her work engaged with the dominant philosophers of the time - among them Hume, Berkeley, and Reid. In particular, her 1827 volume Essays on the Perception of an External Universe outlines a theory of causation, perception, and knowledge which Shepherd presents (...) as an alternative to what she sees as the mistaken views of Berkeley and Hume. What she ultimately presents is an original and systematic metaphysics and epistemology. Shepherd's Essays consists of two parts. The first is a theory of perception and knowledge of the external world, which is designed to rebut idealism and skepticism about the external world and show that our ordinary beliefs are based on reason. The second is a collection of essays on topics in metaphysics and epistemology, including the immateriality and eternity of the mind, the relationship between mind and body, the possibility of miracles, the association of ideas, the relationship between physical and mathematical reasoning, and the epistemology of testimony. Antonia LoLordo's edition of Shepherd's Essays includes scholarly notes throughout the text that provide historical and philosophical context and expand on the major concepts of Shepherd's system. Her extensive introduction to Shepherd's life and works surveys some of the major points of Shepherd's system, points out directions for future research, and offers guidance for readers planning to teach her work in their courses. This volume is an invaluable primary resource for scholars, graduate students, and undergraduates interested in metaphysics, epistemology, and early modern philosophy. (shrink)

Policies promoted and adopted for allocating ventilators during the COVID-19 pandemic have often prioritised healthcare workers or other essential workers. While the need for such policies has so far been largely averted, renewed stress on health systems from continuing surges, as well as the experience of allocating another scarce resource—vaccination—counsel revisiting the justifications for such prioritisation. Prioritising healthcare workers may have intuitive appeal, but the ethical justifications for doing so and the potential harms that could follow require careful analysis. Ethical (...) justifications commonly offered for healthcare worker prioritisation for ventilators rest on two social value criteria: instrumental value, also known as the ‘multiplier effect’, which may preserve the ability of healthcare workers to help others, and reciprocity, which rewards past usefulness or sacrifice. We argue that these justifications are insufficient to over-ride the common moral commitment to value each person’s life equally. Institutional policies prioritising healthcare workers over other patients also violate other ethical norms of the healthcare professions, including the commitment to put patients first. Furthermore, policy decisions to prioritise healthcare workers for ventilators could engender or deepen existing distrust of the clinicians, hospitals and health systems where those policies exist, even if they are never invoked.

A recent legal case involving an ambiguous diagnosis in a woman with a severe disorder of consciousness raises pressing questions about treatment withdrawal in a time when much of what experts know about disorders of consciousness is undergoing revision and refinement. How much should diagnostic certainty about consciousness matter? For the judge who refused to allow withdrawal of artificial nutrition and hydration, it was dispositive. Rather than relying on substituted judgment or best interests to determine treatment decisions, he ruled that (...) withdrawal was categorically prohibited, even as he concluded that Hannah Capes was more likely than not in a permanent vegetative state. In many jurisdictions, his decision would likely be consistent with existing law. Evolving technological advances have demonstrated that biologically distinct diagnoses incorporated into state laws may be difficult to establish even under ideal conditions. We offer the Capes case for purposes of examining the consequences of enshrined legal distinctions between permanent vegetative state and other severe disorders of consciousness. Insistence on proof of the permanent absence of consciousness before treatment withdrawal is allowed fails to respect the rights of persons with disorders of consciousness. Even the well-established rights to treatment withdrawal for those in a permanent vegetative state may be in jeopardy if reform is not undertaken. (shrink)

Lady Mary Shepherd’s critique of Hume’s account of causation, his worries about knowledge of matters of fact, and the contention that it is possible for the course of nature to spontaneously change relies primarily on three premises, two of which – that objects are merely bundles of qualities and that the qualities of an object are individuated by the causal powers contributed by those qualities – anticipate contemporary metaphysical views in ways that she should be getting credit for. (...) The remaining premise – that it is impossible for an object to begin to exist uncaused – seems more old fashioned. I argue that Shepherd can do without her old-fashioned premise and that she provides the materials for arguing that her remaining premises demonstrate a stronger anti-Humeanism than is maintained even by the contemporary representatives of those views, even though she may have to concede more to Humeanism than she would like. (shrink)

Shepherd propounds a theory of mind with a fair claim to be better than Hume’s at explaining the sources of commonly held human beliefs about causal necessity due largely to her relational theory of sense perception. In comparison with Hume’s account, it incorporates a more sophisticated treatment of mental representation, especially the role of relational structure and logical form. Most important, perhaps, Shepherd’s theory enforces the division, obscured by Hume, between the evidence of necessity and the metaphysical foundation (...) of necessity. (shrink)

Mary Shepherd (1777–1847) was a fierce and brilliant critic of Berkeley and Hume, who moreover offered strikingly original positive views about the nature of reality and our access to it which deserve much more attention (and credit, since she anticipates many prominent views) than they have received thus far. By way of illustration, I focus on Shepherd's 1824 Essay Upon the Relation of Cause and Effect, Controverting the Doctrine of Mr. Hume, Concerning the Nature of that Relation (...) (ERCE). After a brief setup, I canvas certain of her trenchant objections to Hume’s argumentation; I then present the positive core of her response to Hume, which consists in providing novel accounts of how reason alone or reason coupled with experience can justify, first, that every effect must have a cause, and second, that it is necessary that like causes produce like effects. Among other contributions here, Shepherd provides a distinctively metaphysical argument for the claim that nothing can begin to exist 'of itself' (going beyond an appeal to the Principle of Sufficient Reason, in particular), and leverages difference-making considerations to make the case that a single 'experimentum crucis' can justify causal belief (anticipating Mill's 'method of difference'). I close by highlighting salient features of Shepherd's metaphysics of causation, whereby causation is singularist and local (anticipating Ducasse and Anscombe) and involves synchronic interactions (anticipating Mill's and certain contemporary accounts), and according to which objects are essentially characterized by their causes and effects (anticipating contemporary causal or dispositional essentialist positions). (shrink)

This paper examines the role of reason in Shepherd's account of acquiring knowledge of the external world via first principles. Reason is important, but does not have a foundational role. Certain principles enable us to draw the required inferences for acquiring knowledge of the external world. These principles are basic, foundational and, more importantly, self‐evident and thus justified in other ways than by demonstration. Justificatory demonstrations of these principles are neither required, nor possible. By drawing on textual and contextual (...) evidence, I will show that Shepherd should have said that we know the first principles of any science, in general, and that “everything which begins to exist must have a cause”, in particular, via intuition, not via reason. Reasoning about such principles can help their self‐evidence shine through in certain cases; their justification, and our being justified in believing them, does not come from this reasoning, however. (shrink)

This guide leads readers systematically through the arguments of Mary Shepherd's two books. Chapters 1-4 cover the arguments in the Essay Upon the Relation of Cause and Effect (1824), where Shepherd argues that causal principles can be known by reason to be necessary truths and that causal inferences can be rationally justified. Shepherd's primary target in this work is Hume, but she also addresses the views of Thomas Brown and William Lawrence. Shepherd considered her second (...) book, Essays on the Perception of an External Universe, and Other Subjects Connected with the Doctrine of Causation (1827), to be an extension of the earlier project on causation; here she appeals to the causal principles established in the first book to argue that we can know through reason that an external world of continually-existing objects must exist independently of us, as the causes of our sensations. Chapter 5 of this Guide addresses Shepherd's accounts of sensation and reasoning; Chapters 6-9 lead the reader through the arguments of the Essays, as well laying out Shepherd's views on skepticism and Berkeleyan idealism, her accounts of mind and body, her philosophy of religion, and the solutions she offers to two puzzles about vision.

the philosophical writings ofx Lady Mary Shepherd were apparently well regarded in her own time, but dropped out of view in the mid-nineteenth century.1 Some historians of philosophy have recently begun attending to the distinctive arguments in Shepherd's two books, but the secondary literature that exists so far has largely focused on her critiques of Hume and Berkeley. However, many other themes and arguments in Shepherd's writings have not yet been explored. This paper takes up one (...) such issue, what Shepherd means by 'mind,' 'soul,' and 'self.' Shepherd held the unusual view that the mind is an enduring capacity that causes (whether on its own or in conjunction with other partial causes, such as... (shrink)

In her last known piece of work Lady Mary Shepherd’s Metaphysics (1832), Mary Shepherd writes that “mind, may inhere in definite portions of matter […] or of infinite space” (LMSM 699). Shepherd thus suggests that a mind – a “capacity for sensation in general” (e.g., EPEU 16) – may have a spatial location. This is prima facie surprising given that she is committed to the view that the mind is unextended. In this paper, we argue (...) that Shepherd can consistently honor both of these commitments. We argue, first, that even though finite minds, due to their unextendedness cannot, to use Shepherd’s term, ‘occupy’ space as material bodies do, such minds can nonetheless be said to have a spatial location in virtue of what we call their presence, or what Shepherd calls ‘inherence’, in a material body. Second, we argue that, in a similar way, the divine mind is present throughout the whole of space and is thus omnipresent. We then argue that, in contrast to finite minds, the divine mind does not require a body to be present in space. Rather, we contend, God’s omnipresence might be best understood in a ‘holenmerist’ sense, where the divine mind is wholly present in every part of creation. (shrink)

In several early 19th century works, Mary Shepherd articulates a theory of causation that is intended to respond to Humean skepticism. I argue that Shepherd's theory should be read in light of the science of the day and her conception of her place in the British philosophical tradition. Reading Shepherd’s theory in light of her conception of the history of philosophy, including her claim to be the genuine heir of Locke, illuminates the broader significance of her (...) attempt to reinstate reason as the source of scientific knowledge. Reading Shepherd's theory in light of the science of the day helps make plausible her claim that there are robust natural kinds in nature, defined by their causal powers: this is precisely what then-recent advances in chemistry hold.

Mary Shepherd and the Causal Relation - Part One -/- Part One gives context to the life and work of Lady Mary Shepherd. It weaves together the stories of her ancestors, her own stories and the wider social, historical and philosophical context. The aim is to evoke a world from which to mark the emergence of Mary Shepherd, Scotland’s first female philosopher.

The aims of this paper are twofold. First, I offer a new insight into Shepherd’s theory of mind by demonstrating that she distinguishes a threefold ‘Variety of Intellect’, that is, three kinds of minds grouped according to their cognitive limitations. Following Shepherd, I call them (i) minds afflicted with idiocy, (ii) inferior understandings, and (iii) sound understandings. Second, I show how Shepherd’s distinction informs her theory of education. While Shepherd claims that her views serve to improve (...) educational practices, she does not explain how her threefold ‘Variety of intellect’ does so. I argue that Shepherd’s distinction contributes to her aim by providing pedagogues with a more comprehensive grasp of the various cognitive limitations of the people in their care. This allows the former to adjust their expectations and to provide need-oriented guidance. (shrink)

The aim of this paper is twofold. First, I argue that Mary Shepherd has a dispositional understanding of God, matter, and finite minds. That is, she understands all of them as dispositions or powers (two terms I will use interchangeably). Second, I aim to shed light on the emanationist picture suggested by Shepherd’s remarks in her second book Essays on the Perception of an External Universe (EPEU). For instance, Shepherd calls ‘animate’ and ‘inanimate nature’ a divine (...) ‘emanation’ (EPEU 190) and describes finite beings as ‘outgoings’ that come ‘forth’ from God (EPEU 189, 190, 219). Because of this emanationist language, in conjunction with Shepherd’s dispositional understanding of God, matter, and mind, it is helpful to use Jennifer McKitrick’s (2003) distinction between bare and based disposition. For Shepherd’s remarks suggest that the powers that are matter and finite minds are akin to based dispositions because they are caused by and subsist in virtue of God. But since God – ‘THE GREAT FIRST CAUSE’ (ERCE 119) ‘who began not to be’ (EPEU 219) is also a power, the Deity functions similarly to a bare or ungrounded disposition, while matter and finite minds are similar to a ‘based dispositions’ (McKitrick 2003).

There has recently been a resurgence of interest in the early nineteenth century Scottish philosopher Mary Shepherd. This Element is intended to provide an overview of Shepherd's system, including her views on the following wide range of topics: causation, induction, knowledge of the external world, matter, life, animal cognition, the relationship between mind and body, the immortality of the soul, the existence of God, miracles, and the nature of divine creation. The author also provides an overview of (...) relevant secondary literature and argues for their own interpretation of Shepherd's metaphysics. (shrink)

This is the first modern edition of an important work by a previously neglected early 19th century woman philosopher, Mary Shepherd. Shepherd develops a distinctive philosophical system that can be seen as a competitor to Kant's Transcendental Idealism. The edition is aimed at researchers in early modern philosophy and is also intended to be used in graduate and undergraduate courses. It contains a concise introduction as guide for the reader.

The philosophical writings of Lady Mary Shepherd (1777–1847) reveal an astute and lively intellect. In An Essay upon the Relation of Cause and Effect (1824) and Essays on the Perception of an External Universe, and Other Subjects Connected with the Doctrine of Causation (1827), Shepherd engaged critically with the views of Hume, Berkeley, Reid, Stewart, de Condillac, and others, but she also presented an original and carefully argued philosophical system of her own. Highly regarded in her day, (...) Shepherd's work faded into obscurity after her death; this collection of selections from her writings is intended to bring her work back into focus for students and scholars. Selections include her writings about causation, knowledge of the external world, mathematical and physical induction, belief in miracles and God, and mind and body. This volume also includes an 1828 essay Shepherd published on vision and selections from her 1832 magazine article, "Lady Mary Shepherd's Metaphysics.". (shrink)

Virginia Woolf, in A Room of One’s Own, asked why there were no women writers before 1800. If she had been thinking about philosophers instead of writers in the traditional women’s areas of plays and fiction, she might have asked why there were no women philosophers at all, for I suspect that most people would find it very hard to name a woman philosopher before the present day. To help her in answering her question, she invented a fictional character, Judith (...) Shakespeare, a sister to William Shakespeare. The conditions of Judith’s life made it impossible for her to write, and so Woolf speculated that the women who would have been writers did not lead the kinds of lives that permitted them to realize their talents. Woolf’s image of Judith Shakespeare is a very powerful one but her speculation is only half right. There undoubtedly were many women in the past who would have been talented writers or philosophers if their lives had been different, but Judith Shakespeare’s image can also blot out our knowledge of women who, contrary to Woolf’s speculation, did exist and did write. Indeed, we know now there were even women who wrote philosophy. These women were in many ways exceptional, for Woolf is quite right that most women did not live either with enough privacy or with enough income to allow them to write. Often, they were members of the aristocracy, whose position enabled them to behave eccentrically, sometimes to be able to demand privacy, and sometimes to be able to invite contacts with leading intellectuals. Quite often, these women were childless, which in an age before birth control made them exceptions to the general rule, and at a time when many women were bearing their last child in their forties, was the only thing that could have given them private time. Nevertheless, research in the last ten or fifteen years has uncovered the work of quite a number of these women: for example, Princess Elizabeth of Bohemia, the Electress Sophie, Queen Christina of Sweden, Queen Sophie Charlotte of Prussia, Anne, Lady Conway, Mary Astell, Damaris, Lady Masham, Catharine Trotter Cockburn, Emilie du Chatelet, Catherine Macaulay, Lady Mary Shepherd, and many more. Woolf’s question then comes up again in a slightly different form. Why is it that the work of these women was for so long unknown? Why do so many people even today remain ignorant of the existence of women philosophers before the present day? I am not going to answer this question directly; in fact, I suspect it has multiple answers. Instead, I am going to present a case study from amongst all the cases of all of these women. I hope by considering the history of this woman, and, in particular, considering the way in which she was read, it will be possible to gain some insights into the ways in which women have failed to be incorporated into philosophical history. The woman I am going to discuss is Lady Mary Shepherd. Mary Shepherd actually falls outside of Woolf’s target date of 1800, since she flourished in the first half of the nineteenth century, but this merely reflects my point about the greater ignorance that prevails about women in philosophy.

This paper explores the role that Mary Shepherd's (1777–1847) acceptance of the so-called imago-dei thesis plays for her account of the human mind. That is, it analyses Shepherd's commitment to the doctrine that humans are created in the image of God, (see Gen. 1, 26–7) parts of which Shepherd quotes in Essays on the Perception of an External Universe (EPEU), 157, and the ways it informs her understanding of the human mind. In particular, it demonstrates how (...) this thesis informs her understanding of the cognitive and moral capacities of the human mind. In other words, I argue that her commitment to this thesis explains why she believes that human beings are capable of reaching the “higher acquirement of intelligence” and the “completion of virtuous habits” (EPEU 381). Thus, this paper highlights the relevance of Shepherd's theological assumptions to (the ever-growing number of) scholars interested in her understanding of the mind. (shrink)

In this paper I argue for a novel interpretation of Shepherd’s notion of selfhood. In distinction to Deborah Boyle’s interpretation, I contend that Shepherd differentiates between the mind and the self. The latter, for Shepherd, is an effect arising from causal interactions between mind and body – specifically those interactions that give rise to our present stream of consciousness, our memories, and that can unite these two. Thus, the body plays a constitutive role in the formation of (...) the self. The upshot of this interpretation is that it can dissolve the problem of individuating mind that Boyle identifies. Briefly, the problem consists in Shepherd seemingly individuating minds in terms of their associated bodies and bodies in terms of the minds they are united with. My interpretation, however, allows to see that Shepherd neither wants nor needs to individuate the mind in isolation of the body and to read the passages, in which the problem seems to arise, as being about what makes living beings individual – with mind and body both playing a crucial role in this context.

Lady Mary Shepherd argued for distinctive accounts of causation, perception, and knowledge of an external world and God. However, her work, engaging with Berkeley and Hume but written after Kant, does not fit the standard periodisation of early modern philosophy presupposed by many philosophy courses, textbooks, and conferences. This paper argues that Shepherd should be added to the canon as a Scottish philosopher. The practical reason for doing so is that it would give Shepherd a disciplinary (...) home, opening up additional possibilities for research and teaching. The philosophical reason is that her views share certain features characteristic of canonical Scottish philosophers. (shrink)

'This collection confirms that Mary Shepherd is an unjustly neglected figure in modern philosopher. It will be especially interesting to students of Berkeley and Hume.' --David Raynor Very little is known about the life and work of Lady Mary Shepherd (1777--1847), and yet she is undoubtedly one of the most important women philosophers of the early modern period. Whewell is reputed to have used one of her books as a text at Cambridge, and Sir Charles Lyell (...) said of her that she was an 'unanswerable logician, in whose argument it was impossible to find a loophole or flaw'. Exceptionally well read and analytically clear, she made a significant scholarly contribution to the philosophical discussion and debate surrounding the work of Hume, Berkeley and others. This, the first modern edition of Shepherd's writings, includes her two major philosophical works: An Essay upon the Relation of Cause and Effect (1824), a critique of Hume's view of causality, and Essays on the Perception of an External Universe and Other Subjects (1827), a refutation of Berkeley's idealism. Also included is her first, anonymous, publication, Enquiry respecting the Relation of Cause and Effect (1819) and two shorter pieces. There is a growing interest in the contribution of women writers to the history of philosophy. However, limited access to original texts has prevented a serious and systematic examination of their doctrines. Shepherd's philosophical works deserve the careful consideration of contemporary historians and philosophers, but until now have been largely unavailable to the modern reader. A reevaluation of her works is long overdue and this new collection is a welcome addition to Thoemmes Press's list. --very rare works by an eminent and increasingly prominent woman philosopher of the Scottish Enlightenment.

In addition to the 1824 and 1827 books known to have been written by Lady Mary Shepherd, another philosophical treatise, published in 1819, has sometimes been attributed to her. While evidence for this attribution has so far been inconclusive, this paper provides reasons for thinking that Shepherd was not, in fact, the author of this book. New external evidence is provided to show that the author was James Milne, an Edinburgh architect and engineer.

Recent work on Mary Shepherd has largely focused on her metaphysics, especially as a response to Berkeley and Hume. However, relatively little attention has thus far been paid to the epistemological aspects of Shepherd’s program. What little attention Shepherd’s epistemology has received has tended to cast her as providing an unsatisfactory response to the skeptical challenge issued by Hume. For example, Walter Ott and Jeremy Fantl have each suggested that Shepherd cannot avoid Hume’s inductive skepticism (...) even if she is granted her metaphysics. In this paper, I examine Shepherd’s epistemology and argue that her response to Hume is more successful than the current literature suggests. In particular, I argue that, if Shepherd is granted her metaphysics, she can answer Hume’s demand for a rational justification of ordinary inductive inferences via a deductively justified uniformity principle and an appeal to parsimony.

Mary Shepherd assigns reason a central role in her philosophical system, and so to understand that system we must understand her conception of reason. Does she, like Hume, take reason to be a mere matter of factual process that operates over independently contentful representations? Does she, like Descartes, take it to be a process that is intended to track the rational relations among such representations? Or does she, like Kant, take reason to be a structural feature of representations (...) without which they would not have content at all? I argue that Shepherd's understanding of reason is broadly Kantian. Reason is a causal process whereby non-representational sensible qualities are combined in order to form representations of objects as loci of causal powers. These representations represent their objects as the external, continuously and independently existing, causes of the sensible qualities from which they have been constructed, and also as having causal powers to combine with other objects to have other effects. These representations are not only the result of a process of reasoning, but are also constituted by the rational relations into which reason puts them. Reason is both the causal process that forms such representations, and the structure of those representations themselves. (shrink)

Shepherd defends an account of the universe founded on two causal principles: that effects necessarily have causes, and that like causes have like effects. Folding mind into the class of natural phenomena governed by these principles, Shepherd naturalizes the mind, but in doing so she sets herself the challenge of explaining how, within a deterministic universe, agents can be necessary causes of their own actions. With special attention to Shepherd’s resistance to materialism and to any reduction of (...) the mental, the paper argues that we can read Shepherd as leveraging her original theory of causation to develop a distinctive compatibilist view of the psychology of intention, one that makes agents the necessary causal sources of their own actions.

Lady Mary Shepherd holds that the relation of cause and effect consists of the combination of two objects to create a third object. She also holds that this account implies that causes are synchronous with their effects. There is a single instant in which the objects that are causes combine to create the object which is their effect. Hume argues that cause and effect cannot be synchronous because if they were then the entire chain of successive causes and (...) effects would all collapse into a single moment, and succession would not be possible. I argue that Shepherd has a ready, although implicit response, to Hume’s argument. Since causation is combination on Shepherd’s view, she is free to hold that there are times in between those instants in which combinations occur, during which times other, non-combinatory changes occur, which changes account for succession.

In 1827, Lady Mary Shepherd published Essays on the Perception of an External Universe, which offers both an argument for the existence of a world of external bodies existing outside our minds and a criticism of Berkeley's argument for idealism in A Treatise Concerning the Principles of Human Knowledge. In this paper, I evaluate Margaret Atherton's criticisms of Shepherd's case against Berkeley, and provide reasons for thinking that, although Shepherd's particular criticisms of Berkeley do not succeed, (...) she correctly identifies an important problem to which Berkeley's reasoning is subject.

The Shape of Agency offers interlinked explanations of the basic building blocks of agency, as well as its exemplary instances. The first part offers accounts of a collection of related phenomena that have long troubled philosophers of action: control over behaviour, non-deviant causation, and intentional action. These accounts build on earlier work in the causalist tradition, and undermine the claims made by many that causalism cannot offer a satisfying account of non-deviant causation, and therefore fails as an account of intentional (...) action. The second part turns to modes of agentive excellence—ways that agents display quality of form—providing a novel account of skill, including an account of the ways that agents display more or less skill. Shepherd discusses the role of knowledge in skill, and concludes that while knowledge is often important, it is inessential. This leads to a discussion of the way that knowledge of action and knowledge of how to act informs action execution. Knowledgeable action includes a unique epistemic underpinning: in knowledgeable action, the agent has authoritative knowledge of what she is doing and how she is doing it when and because she is poised to control her action by way of practical reasoning.

The rise of experimental philosophy has placed metaphilosophical questions, particularly those concerning concepts, at the center of philosophical attention. X-phi offers empirically rigorous methods for identifying conceptual content, but what exactly it contributes towards evaluating conceptual content remains unclear. We show how x-phi complements Rudolf Carnap’s underappreciated methodology for concept determination, explication. This clarifies and extends x-phi’s positive philosophical import, and also exhibits explication’s broad appeal. But there is a potential problem: Carnap’s account of explication was limited to empirical and (...) logical concepts, but many concepts of interest to philosophers are essentially normative. With formal epistemology as a case study, we show how x-phi assisted explication can apply to normative domains. (shrink)

It seems obvious that phenomenally conscious experience is something of great value, and that this value maps onto a range of important ethical issues. For example, claims about the value of life for those in a permanent vegetative state, debates about treatment and study of disorders of consciousness, controversies about end-of-life care for those with advanced dementia, and arguments about the moral status of embryos, fetuses, and non-human animals arguably turn on the moral significance of various facts about consciousness. However, (...) though work has been done on the moral significance of elements of consciousness, such as pain and pleasure, little explicit attention has been devoted to the ethical significance of consciousness. In this book Joshua Shepherd presents a systematic account of the value present within conscious experience. This account emphasizes not only the nature of consciousness, but the importance of items within experience such as affect, valence, and the complex overall shape of particular valuable experiences. Shepherd also relates this account to difficult cases involving non-humans and those with disorders of consciousness, arguing that the value of consciousness influences and partially explains the degree of moral status a being possesses, without fully determining it. The upshot is a deeper understanding of both the moral importance of phenomenal consciousness and its relations to moral status. This book will be of great interest to philosophers and students of ethics, bioethics, philosophy of psychology, philosophy of mind and cognitive science. (shrink)
