No mental phenomenon is more central than consciousness to an adequate understanding of the mind. Nor does any mental phenomenon seem more stubbornly to resist theoretical treatment. Consciousness is so basic to the way we think about the mind that it can be tempting to suppose that no mental states exist that are not conscious states. Indeed, it may even seem mysterious what sort of thing a mental state might be if it is not a conscious state. On this way (...) of looking at things, if any mental states do lack consciousness, they are exceptional cases that call for special explanation or qualification. Perhaps dispositional or cognitive states exist that are not conscious, but nonetheless count as mental states. (shrink)

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.

Shepherd’s argument against Hume’s thesis that an object can begin its existence uncaused has received short shrift in the secondary literature. I argue that the key to understanding that argument’s success is understanding its dialectical context. Shepherd sees the dialectical situation as follows. Hume presents an argument against Locke and Clarke the conclusion of which is that an object can come into existence uncaused. An essential premise of that argument is Hume’s theory of mental representation. Hume’s theory of mental representation, (...) however, is itself implausible and unsupported. Therefore, one need not accept this premise or this conclusion. Thus, Shepherd proceeds to her discussion of the relation of cause and effect free to help herself to the thesis that every beginning of existence must have a cause. Additionally, she elsewhere pays down the debt she incurs in that argument by presenting her own alternative theory of mental representation, which is both plausible in its own right, and can account for the error that she takes Hume to make.

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.

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.

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)

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.

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (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.

James Mill (1773-1836) is today best known as Jeremy Bentham's chief disciple and John Stuart Mill's father. Yet Mill himself was a formidable and important Utilitarian thinker in his own right, who earned the respect of even those who disagreed with him. His range was enormous (historian, political philosopher, psychologist, educational theorist, and economist), repeatedly crossing the disciplinary boundaries we take for granted today. This volume presents a wide sampling of Mill's political writings and polemical essays. It begins with his (...) classic work, the Essay on Government, it also includes pieces on the protection of rights, the importance of education, the free press, the secret ballot, and government's use of punishment against those who violate the rights of fellow citizens. The collection concludes with Macauley's famous critique of the Essay, and Mill's heretofore unnoticed reply in his Fragment on Mackintosh (1835). This is the first time that such a selection of Mill's political works has appeared as one volume. (shrink)

Consciousness and Mind presents David Rosenthal's influential work on the nature of consciousness. Central to that work is Rosenthal's higher-order-thought theory of consciousness, according to which a sensation, thought, or other mental state is conscious if one has a higher-order thought that one is in that state. The first four essays develop various aspects of that theory. The next three essays present Rosenthal's homomorphism theory of mental qualities and qualitative consciousness, and show how that theory fits with and helps sustain (...) the HOT theory. A crucial feature of homomorphism theory is that it individuates and taxonomizes mental qualities independently of the way we're conscious of them, and indeed independently of our being conscious of them at all. So the theory accommodates the qualitative character not only of conscious sensations and perceptions, but also of those which fall outside our stream of consciousness. Rosenthal argues that, because this account of mental qualities makes no appeal to consciousness, it enables us to dispel such traditional quandaries as the alleged conceivability of undetectable quality inversion, and to disarm various apparent obstacles to explaining qualitative consciousness and understanding its nature. Six further essays build on the HOT theory to explain various important features of consciousness, among them the complex connections that hold in humans between consciousness and speech, the self-interpretative aspect of consciousness, and the compelling sense we have that consciousness is unified. Two of the essays, one an extended treatment of homomorphism theory, appear here for the first time. There is also a substantive introduction, which draws out the connections between the essays and highlights their implications. (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.
