I propose to consider the question, "Can machines think?" This should begin with definitions of the meaning of the terms "machine" and "think." The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words "machine" and "think" are to be found by examining how they are commonly used it is difficult to escape the conclusion that the meaning and the answer to (...) the question, "Can machines think?" is to be sought in a statistical survey such as a Gallup poll. But this is absurd. Instead of attempting such a definition I shall replace the question by another, which is closely related to it and is expressed in relatively unambiguous words. The new form of the problem can be described in terms of a game which we call the 'imitation game." It is played with three people, a man (A), a woman (B), and an interrogator (C) who may be of either sex. The interrogator stays in a room apart front the other two. The object of the game for the interrogator is to determine which of the other two is the man and which is the woman. He knows them by labels X and Y, and at the end of the game he says either "X is A and Y is B" or "X is B and Y is A." The interrogator is allowed to put questions to A and B. We now ask the question, "What will happen when a machine takes the part of A in this game?" Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman? These questions replace our original, "Can machines think?". (shrink)

This compilation offers a unique synthesis of the traditional branches of Eastern thought by drawing upon their historical connections and common foundations in mystical experience.

Bridging the gap between the world of science and the realm of the spiritual, B. Alan Wallace introduces a natural theory of human consciousness that has its roots in contemporary physics and Buddhism. Wallace's "special theory of ontological relativity" suggests that mental phenomena are _conditioned_ by the brain, but do not _emerge_ from it. Rather, the entire natural world of mind and matter, subjects and objects, arises from a unitary dimension of reality that is more fundamental than these dualities, (...) as proposed by Wolfgang Pauli and Carl Jung. To test his hypothesis, Wallace employs the Buddhist meditative practice of _samatha_, refining one's attention and metacognition, to create a kind of telescope to examine the space of the mind. Drawing on the work of the physicist John Wheeler, he then proposes a more general theory in which the participatory nature of reality is envisioned as a self-excited circuit. In comparing these ideas to the Buddhist theory known as the Middle Way philosophy, Wallace explores further aspects of his "general theory of ontological relativity," which can be investigated by means of _vipasyana_, or insight, meditation. Wallace then focuses on the theme of symmetry in reference to quantum cosmology and the "problem of frozen time," relating these issues to the theory and practices of the Great Perfection school of Tibetan Buddhism. He concludes with a discussion of the general theme of complementarity as it relates to science and religion. The theories of relativity and quantum mechanics were major achievements in the physical sciences, and the theory of evolution has had an equally deep impact on the life sciences. However, rigorous scientific methods do not yet exist to observe mental phenomena, and naturalism has its limits for shedding light on the workings of the mind. A pioneer of modern consciousness research, Wallace offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physicists and philosophers with the time-honored meditative traditions of Buddhism.

What is the basis for arguing that a volunteer army exploits citizens who lack civilian career opportunities? How do we determine that a doctor who has sex with his patients is exploiting them? In this book, Alan Wertheimer seeks to identify when a transaction or relationship can be properly regarded as exploitative--and not oppressive, manipulative, or morally deficient in some other way--and explores the moral weight of taking unfair advantage. Among the first political philosophers to examine this important topic (...) from a non-Marxist perspective, Wertheimer writes about ordinary experience in an accessible yet philosophically penetrating way. He considers whether it is seriously wrong for a party to exploit another if the transaction is consensual and mutually advantageous, whether society can justifiably prohibit people from entering into such a transaction, and whether it is wrong to allow oneself to be exploited. Wertheimer first considers several contexts commonly characterized as exploitive, including surrogate motherhood, unconscionable contracts, the exploitation of student athletes, and sexual exploitation in psychotherapy. In a section outlining his theory of exploitation, he sets forth the criteria for a fair transaction and the point at which we can properly say that a party has consented. Whereas many discussions of exploitation have dealt primarily with cases in which one party harms or coerces another, Wertheimer's book focuses on what makes a mutually advantageous and consensual transaction exploitive and analyzes the moral and legal implications of such exploitation.

Rowlands defends environmentalism, that is, the conjunction of the ontological claim that cognitive processes are not located exclusively inside the skin of cognizing organisms and the epistemological claim that it is not possible to understand the nature of cognitive processes by focusing exclusively on what is occurring inside the skin of cognizing organisms. Chapter 3 is devoted to explaining how environmentalism differs from other forms of externalism about the mental. The crucial points are that the arguments to be presented for (...) the ontological claim do not turn on considerations about the content of mental states, that environmentalism implies a strong form of externalism, and that standard arguments for externalism, based on considerations about content, do not establish the strong form.

There is a traditional conception of sensory experience on which the experiences one has looking at, say, a cat could be had by someone merely hallucinating a cat. Disjunctivists take issue with this conception on the grounds that it does not enable us to understand how perceptual knowledge is possible. In particular, they think, it does not explain how it can be that experiences gained in perception enable us to be in ‘cognitive contact’ with objects and facts. I develop this (...) chal- lenge to the traditional conception and then show that it is possible to accommo- date an adequate account of cognitive contact in keeping with the traditional conception. One upshot of the discussion is that experiences do not bear the explanatory burden placed upon them by disjunctivists. (shrink)

When does a woman give valid consent to sexual relations? When does her consent render it morally or legally permissible for a man to have sexual relations with her? Why is sexual consent generally regarded as an issue about female consent? And what is the moral significance of consent? These are some of the questions discussed in this important book, which will appeal to a wide readership in philosophy, law, and the social sciences. Alan Wertheimer develops a theory of (...) consent to sexual relations that applies to both law and morality in the light of the psychology of sexual relations, the psychology of perpetrators, and the psychology of the victims. He considers a wide variety of difficult cases such as coercion, fraud, retardation, and intoxication. We can all agree that 'no' means 'no'. This book suggests that the difficult question is whether 'yes' means 'yes'. (shrink)

Whose Keeper? is a profound and creative treatise on modernity and its challenge to social science. Alan Wolfe argues that modern liberal democracies, such as the United States and Scandinavia, have broken with traditional sources of mortality and instead have relied upon economic and political frameworks to define their obligations to one another. Wolfe calls for reinvigorating a sense of community and thus a sense of obligation to the larger society.

In recent months, Covid‐19 has devastated African American communities across the nation, and a Minneapolis police officer murdered George Floyd. The agents of death may be novel, but the phenomena of long‐standing epidemics of premature black death and of police violence are not. This essay argues that racial health and health care disparities, rooted as they are in systemic injustice, ought to carry far more weight in clinical ethics than they generally do. In particular, this essay examines palliative and end‐of‐life (...) care for African Americans, highlighting the ways in which American medicine, like American society, has breached trust. In the experience of many African American patients struggling against terminal illness, health care providers have denied them a say in their own medical decision‐making. In the midst of the Covid‐19 pandemic, African Americans have once again been denied a say with regard to the rationing of scarce medical resources such as ventilators, in that dominant and ostensibly race‐neutral algorithms sacrifice black lives. Is there such thing as a “good” or “dignified” death when African Americans are dying not merely of Covid‐19 but of structural racism? (shrink)

Actualists who believe in possible worlds typically regard them as "abstract" objects of some special sort. For example, Alvin Plantinga takes worlds to be maximal possible states-of-affairs, all of which "exist", as actualism requires, but only one of which "obtains". Views like Plantinga's run into difficulty in the interpretation of statements of "iterated" modality, statements about what is "possible" for individuals that "could" exist but that do not actually exist. These statements seem to require the existence of "singular" states-Of-affairs that (...) have nonactual individuals as constituents, a requirement that is incompatible with actualism. One can try to avoid the troublesome singular states-of-affairs by introducing "unexemplified individual essences" and maintaining that these are the true constituents of the required states-of-affairs, rather than the nonactual possibles themselves. However, serious arguments are raised against this employment of individual essences. (shrink)

This paper defends the traditional view that the laws of nature are contingent, or, if some of them are necessary, this is due to analytic principles for the individuation of the law-governed properties. Fundamentally, I argue that the supposed explanatory purposes served by taking the laws to be necessary --showing how laws support counterfactuals, how properties are individuated, or how we have knowledge of properties--are in fact undermined by the continued possibility of the imagined scenarios--this time, described neutrally--which seemed to (...) disprove the claim to necessity in the first place. I speculate that this will be true for any proposed necessary a posteriori truths, and is a basis for rejecting their supposed metaphysical significance. (shrink)

Applies a philosophical analysis of the natural sciences to the social sciences.

Millar argues against the tendency in current philosophical thought to treat sensory experiences as a peculiar species of propositional attitude. While allowing that experiences may in some sense bear propositional content, he presents a view of sensory experiences as a species of psychological state. A key theme in his general approach is that justified belief results from the competent exercise of conceptual capacities, some of which involve an ability to respond appropriately to current experience. In working out this approach the (...) author develops a view of concepts and their mastery, explores the role of groundless beliefs drawing on suggestions of Wittgenstein, illuminates aspects of the thought of Locke, Hume, Quine, and Goldman, and finally offers a response to a sophisticated variety of scepticism.

An explanation is given of why it is in the nature of inquiry into whether or not p that its aim is fully achieved only if one comes to know that p or to know that not-p and, further, comes to know how one knows, either way. In the absence of the latter one is in no position to take the inquiry to be successfully completed or to vouch for the truth of the matter in hand. An upshot is that (...) although knowledge matters because truth matters this should not be understood to mean that knowledge matters because true belief matters. (shrink)

The phenomenon of rigid designation - in particular, de jure rigidity - is typically treated metaphysically. The picture is: reference is gained in a way that puts no constraints on what an object in other worlds, or counterfactual situations must be like, in order to be the referent of that term, other than 'being this thing'. This allows 'pure metaphysical' investigation into, and discovery of 'the nature' of the referent. It is argued that this presupposes a 'privileged' ontology, of a (...) sort that is far from obvious. An alternative picture of rigidity is sketched, terms have associated criteria of identity and criteria of application for counterfactual situations. A term is rigid when these coincide. Aside from being a better account of rigidity, it also undermines the picture of rigid terms allowing us to 'metaphysically' investigate the nature of the referent: matters of identity and essence for the referent are settled by these semantic constraints (though it can be done in a way that allows are a posteriori necessities).

Drawing upon ancient Hindu philosophy, the author explores the human psyche and the importance of personal identity.

In 'Philosophy and the Mirror of Nature' Richard Rorty presented his provocation and influential vision of the post-philosophical culture, calling upon professional philosophers to accept that epistemology is dead, that the analytic method is a myth, and that philosophy and science are merely forms of literature.

This article outlines a conception of perceptual-recognitional abilities. These include abilities to recognize certain things from their appearance to some sensory modality, as being of some kind, or as possessing some property. An assumption of the article is that these abilities are crucial for an adequate understanding of perceptual knowledge. The specific aim here is to contrast those abilities with abilities or competences as conceived in the virtue-theoretic literature, with particular reference to views of Ernest Sosa and John Greco. In (...) the course of the discussion, it is emphasized that the notion of exercising a perceptual-recognitional ability is a success notion: exercising such an ability is nothing less than acquiring knowledge. Even so, the view can make sense of our fallibility. It can also be defended in the face of an objection stemming from consideration of what are here called success-rate abilities. (shrink)

This book, first published in 1987, investigates what distinguishes the part of human behaviour that is action from the part that is not. The distinction was clearly drawn by Socrates, and developed by Aristotle and the medievals, but key elements of their work became obscured in modern philosophy, and were not fully recovered when, under Wittgenstein’s influence, the theory of action was revived in analytical philosophy. This study aims to recover those elements, and to analyse them in terms of a (...) defensible semantics on Fregean lines. Among its conclusions: that actions are bodily or mental events that are causally explained by their doers’ propositional attitudes, especially by their choices or fully specific intentions; that choice cannot be reduced to desire and belief, and hence that the traditional concept of will as intellectual appetite must be revived.

Can we know anything for certain? There are those who think we can (traditionally labeled the "dogmatists") and those who think we cannot (traditionally labeled the "skeptics"). The theory of knowledge, or epistemology, is the great debate between the two. This book is an introductory and historically-based survey of the debate. It sides for the most part with the skeptics. It also develops out of skepticism a third view, fallibilism or critical rationalism, which incorporates an uncompromising realism about perception, science, (...) and the nature of truth. (shrink)

Causal relations among components and activities are intentionally misrepresented in mechanistic explanations found routinely across the life sciences. Since several mechanists explicitly advocate accurately representing factors that make a difference to the outcome, these idealizations conflict with the stated rationale for mechanistic explanation. We argue that these idealizations signal an overlooked feature of reasoning in molecular and cell biology—mechanistic explanations do not occur in isolation—and suggest that explanatory practices within the mechanistic tradition share commonalities with model-based approaches prevalent in population (...) biology.

Although natural philosophers have long been interested in individuality, it has been of interest to contemporary philosophers of biology because of its role in different aspects of evolutionary biology. These debates include whether species are individuals or classes, what counts as a unit of selection, and how transitions in individuality occur evolutionarily. Philosophical analyses are often conducted in terms of metaphysics (“what is an individual?”), rather than epistemology (“how can and do researchers conceptualize individuals so as to address some of (...) their scientific goals?”). We review several philosophical distinctions in order to shift attention from metaphysics to epistemology. Many controversies involve epistemological differences rather than metaphysical disagreement. This implies that a pluralist stance about individuality in biology is warranted and has metaphysical consequences because the pluralism emerges from the diversity of scientific interests that investigate the complexity of living phenomena.

The paper explains what disjunctivism is and explores its implications for skepticism. Following an account of Paul Snowdon’s conception of a disjunctivist account of perceptual experience the the focus is on how disjunctivism has figured in the epistemological work of John McDowell. A conception of recognitional abilities is deployed to expand on McDowell’s position. Finally, there is consideration of whether McDowell offers a satisfactory response to skepticism, taking account of criticism’s made by Crispin Wright.

What do people consciously experience when they read? There has been almost no rigorous research on this question, and opinions diverge radically among both philosophers and psychologists. We describe three studies of the phenomenology of reading and its relationship to memory of textual detail and general cognitive abilities. We find three main results. First, there is substantial variability in reports about reading experience, both within and between participants. Second, reported reading experience varies with passage type: passages with dialogue prompted increased (...) reports of inner speech, while passages with vivid visual detail prompted increased reports of visual imagery. Third, reports of visual imagery experiences, inner speech experiences, and experiences of conscious visual perception of the words on the page were at best weakly related to general cognitive abilities and memory of visual and auditory details.

Roger Jones asks what Newtonian realists should be realists about, given that there are four empirically equivalent formulations of Newtonian mechanics which have different ontological commitments and explanatory mechanisms. A realist answer is sketched: Newtonians should be realists about what the best metaphysical considerations dictate, where the best metaphysical considerations are those which have yielded the best physics. Metaphysical considerations are required within physics, just as they are required to eliminate idealist and surrealist theories which are empirically equivalent to realist (...) ones. Realists must reject the positivist assumption that empirically equivalent theories are explanatory and evidential equivalents, too. (shrink)

How does the human animal who thinks and loves relate to criminal justice? This essay takes up the idea of a moral psychology of guilt promoted by Bernard Williams and Herbert Morris. Against modern liberal society’s ‘peculiar’ legal morality of voluntary responsibility, it pursues Morris’s ethical account of guilt as involving atonement and identification with others. Thinking of guilt in line with Morris, and linking it with the idea of moral psychology, takes the essay to Freud’s metapsychology in Civilization and (...) Its Discontents. Two conflicting routes to guilt are noted in Freud, one involving internalisation of external anger to suppress destructive instincts, the other loving identification with others in the process of self-formation. This second route is developed through the psychoanalytic thought of Hans Loewald and Jonathan Lear. Following Loewald, the moral psychology of self-formation makes loving identification with others the root of responsibility, guilt and atonement. Following Lear, the moral psychology of guilt developed on these lines renders psychoanalysis part of a broadly understood philosophical project following Aristotelian and Socratic principles. Underlying Morris’s account of guilt is the possibility of ‘prospective identification’, understood as the moral and psychological ground of guilt and reconciliation. This is the rational core of criminal justice, which maintains an uneasy relationship with law’s ‘peculiar’ morality. (shrink)
