In “Of Personal Identity”, Hume attempts to understand why we ordinarily believe in persistent selves. He proposes that this ontological commitment depends on illusions and fictions: the imagination tricks us into supposing that an unchanging core self remains static through the flux and change of experience. Recent work in cognitive science provides a good deal of support for Hume’s hypothesis that common beliefs about the self are founded on psychological biases rather than rational insight or evidence. We naturally believe in (...) personal persistence, according to this emerging research, because we are prone to categorize the world in terms of hidden essences and structure our lives in terms of whole life stories.

The aesthetic skeptic maintains that it is futile to dispute about taste. One and the same work of art might appear beautiful to one person but repellent to another, and we have no reason to prefer one or another of these conflicting verdicts. Hume argues that the skeptic, however, moves too quickly. The crucial question is whether qualified critics will agree on their evaluations. And the skeptic fails to provide sufficient evidence that their verdicts will diverge. We have reason to (...) expect that a consensus will emerge over time, moreover, since aesthetic values are grounded on universal principles of human nature. Skeptics might doubt that there is a natural basis for a standard of taste, but this proposal is supported by recent work in experimental aesthetics and cognitive science. (shrink)

Hume argues that we succumb to the vice of prejudice when we fail to correct negative generalizations about social groups in the face of counter-evidence. We are blameworthy for these biases, moreover, even if they are unavoidable. Hume’s theory of doxastic responsibility entails that his own racial prejudices are deserving of condemnation. In contrast, contemporary vice epistemologists are more inclined to absolve agents of culpability for prejudices beyond their control.

Is PDP Connectionism compatible with Cognitive Linguistics? It is unfortunate that this question has not received the attention it deserves, since at stake is the very possibility of a unified "West Coast Cognitive Science" approach to language. Part I of this paper argues that a systematic approach to the question of compatibility must involve an enumeration and analysis of the general principles used by each research program in their linguistic explanations. This approach is carried out in Parts II and III, (...) and the conclusion is that the explanatory principles of PDP Connectionism are fundamentally data-driven, whereas those of Cognitive Linguistics rely essentially on structure that the mind contributes to language use. Part IV presents several computational models of metaphor and analogy as case studies of the practical difficulties involved in reconciling these two frameworks. Finally, Part V examines the philosophical foundations of their respective explanatory strategies in order to get a clearer view of the theoretical obstacles to a unified account. (shrink)

In Book I, Part I, Section VII of the Treatise, Hume sets out to settle, once and for all, the early modern controversy over abstract ideas. In order to do so, he tries to accomplish two tasks: (1) he attempts to defend an exemplar-based theory of general language and thought, and (2) he sets out to refute the rival abstraction-based account. This paper examines the successes and failures of these two projects. I argue that Hume manages to articulate a plausible (...) theory of general ideas; indeed, a version of his account has defenders in contemporary cognitive science. But Hume fails to refute the abstraction-based account, and as a result, the early modern controversy ends in a stalemate, with both sides able to explain how we manage to speak and think in general terms. Although Hume fails to settle the controversy, he nevertheless advances it to a point from which we have yet to progress: the contemporary debate over abstract ideas in cognitive science has stalled on precisely this point.

There are two major puzzles in Hume’s epistemology. The first involves Hume’s fall into despair in the conclusion of Book One of the Treatise. When Hume reflects back upon the results of his research, he becomes so alarmed that he nearly throws his books and papers into the fire. Why did his investigations push him towards such intense skeptical sentiments? What dark discoveries did he make? The second puzzle concerns the way in which Hume emerges from this skeptical crisis and (...) proceeds with his investigations. Why the sudden change of heart? What accounts for the return of hope? Each of these puzzles represents a serious challenge to traditional approaches to Hume’s epistemology. A proper solution to them requires a careful examination of Hume’s claims about the untrustworthiness of our cognitive faculties as well as his strategy for improving their performance. (shrink)

It is commonly thought that Hume endorses the claim that causal cognition can be fully explained in terms of nothing but custom and habit. Associative learning does, of course, play a major role in the cognitive psychology of the Treatise. But Hume recognizes that associations cannot provide a complete account of causal thought. If human beings lacked the capacity to reflect on rules for judging causes and effects, then we could not (as we do) distinguish between accidental and genuine regularities, (...) and Hume could not (as he does) carry out his science of human nature. One might reply that what appears to be rule-governed behavior might emerge from associative systems that do not literally employ rules. But this response fails: there is a growing consensus in cognitive science that any adequate account of causal learning must invoke active, controlled cognitive processes. (shrink)

Psychology considered as a natural science began as Aristotelian "physics" or "natural philosophy" of the soul, conceived as an animating power that included vital, sensory, and rational functions. C. Wolff restricted the term " psychology " to sensory, cognitive, and volitional functions and placed the science under metaphysics, coordinate with cosmology. Near the middle of the eighteenth century, Krueger, Godart, and Bonnet proposed approaching the mind with the techniques of the new natural science. At nearly the same time, Scottish thinkers (...) placed psychology within moral philosophy, but distinguished its "physical" laws from properly moral laws. British and French visual theorists developed mathematically precise theories of size and distance perception; they created instruments to test these theories and to measure visual phenomena such as the duration of visual impressions. By the end of the century there was a flourishing discipline of empirical psychology in Germany, with a professorship, textbooks, and journals. The practitioners of empirical psychology at this time typically were dualists who included mental phenomena within nature. Accordingly, psychology as a natural scientific disciplines was not invented in the 18th and 19th centuries, but *remade* from the extant empirical psychology. (shrink)

We must rethink the status of Hume’s science of emotions. Contemporary philosophers typically dismiss Hume’s account on the grounds that he mistakenly identifies emotions with feelings. But the traditional objections to Hume’s feeling theory are not as strong as commonly thought. Hume makes several important contributions, moreover, to our understanding of the operations of the emotions. His claims about the causal antecedents of the indirect passions receive support from studies in appraisal theory, for example, and his suggestions concerning the social (...) dimensions of self-conscious emotions can help guide future research in this field. His dual-component hypothesis concerning the processing of emotions, furthermore, suggests a compromise solution to a recalcitrant debate in cognitive science. Finally, Hume’s proposals concerning the motivational influences of pride, and the conventional nature of emotional display rules, are vindicated by recent work in social psychology. (shrink)

David Hume endorses three claims that are difficult to reconcile: (1) sympathy with those in distress is sufficient to produce compassion towards their plight, (2) adopting the general point of view often requires us to sympathize with the pain and suffering of distant strangers, but (3) our care and concern is limited to those in our close circle. Hume manages to resolve this tension, however, by distinguishing two types of sympathy. We feel compassion towards those around us because associative sympathy (...) causes us to mirror their pain and suffering, but our ability to enter into the afflictions of those remote from us involves cognitive sympathy and merely requires us to reflect upon how we would feel in their shoes. This hybrid theory of sympathy receives support from recent work on affective mirroring and cognitive pretense. Hume’s account should appeal to contemporary researchers, therefore, who are interested in the nature of moral imagination. (shrink)

In preparation for examining the place of introspective evidence in scientific psychology, the chapter begins by clarifying what introspection has been supposed to show, and why some concluded that it couldn't deliver. This requires a brief excursus into the various uses to which introspection was supposed to have been put by philosophers and psychologists in the modern period, together with a summary of objections. It then reconstructs some actual uses of introspection (or related techniques, differently monikered) in the early days (...) of experimental psychology. It distinguishes broader and narrower conceptions of introspection and argues that recent critics have tended to misdescribe how introspection was supposed to work. Drawing upon the broader conception of introspection, it argues that introspective reports are ineliminable in perceptual psychology. It concludes with some examples of such ineliminable uses of introspective reports in both earlier and recent perceptual psychology. (shrink)

In Book III, Part 2 of the Treatise, Hume presents a natural history of justice. Self-interest clearly plays a central role in his account; our ancestors invented justice conventions, he maintains, for the sake of reciprocal advantage. But this is not what makes his approach so novel and attractive. Hume recognizes that prudential considerations are not sufficient to explain how human beings – with our propensities towards temporal discounting and free-riding – could have established conventions for social exchange and collective (...) action in commercial societies. This leads him to develop an innovative account of the role that emotional aversions play in establishing trust between strategically rational agents. (shrink)

In Book I, part iv, section 2 of the Treatise, "Of scepticism with regard to the senses," Hume presents two different answers to the question of how we come to believe in the continued existence of unperceived objects. He rejects his first answer shortly after its formulation, and the remainder of the section articulates an alternative account of the development of the belief. The account that Hume adopts, however, is susceptible to a number of insurmountable objections, which motivates a reassessment (...) of his original proposal. This paper defends a version of Hume's initial explanation of the belief in continued existence and examines some of its philosophical implications. (shrink)

In the Natural history of religion, Hume attempts to understand the origin of our folk belief in gods and spirits. These investigations are not, however, purely descriptive. Hume demonstrates that ontological commitment to supernatural agents depends on motivated reasoning and illusions of control. These beliefs cannot, then, be reflectively endorsed. This proposal must be taken seriously because it receives support from recent work on our psychological responses to uncertainty. It also compares quite favorably with its main competitors in the cognitive (...) science of religion. (shrink)

I argue for the moral relevance of a category of individuals I characterize as far-persons. Following Gary Varner, I distinguish near-persons, animals with a " robust autonoetic consciousness " but lacking an adult human's " biographical sense of self, " from the merely sentient, those animals living "entirely in the present." I note the possibility of a third class. Far-persons lack a biographical sense of self, possess a weak autonoetic consciousness, and are able to travel mentally through time a (...) distance that exceeds the capacities of the merely sentient. Far-persons are conscious of and exercise control over short-term cognitive states, states limited by their temporal duration. The animals in question, human and nonhuman, consciously choose among various strategies available to them to achieve their ends, making them subjects of what I call "lyrical experience:" brief and potentially intense pleasures and pains. But their ends expire minute-by-minute, not stretching beyond, I say metaphorically, the present hour. I conclude by discussing the moral status of far-persons. (shrink)

It seems intuitively obvious that metameric matching of color samples entails a loss of information, for spectrophotometrically diverse materials appear the same. This intuition implicitly relies on a conception of the function of color vision and on a related conception of how color samples should be individuated. It assumes that the function of color vision is to distinguish among spectral energy distributions, and that color samples should be individuated by their physical properties. I challenge these assumptions by articulating a different (...) conception of the function of color vision, according to which color vision serves to partition object surfaces into discrimination classes.

With his 1998 book, In Nature’s Interests? Gary Varner proved to be one of our most original and trenchant of environmental ethicists. Here, in the first of a promised two volume set, he makes his mark on another field, animal ethics, leaving an even deeper imprint. Thoroughly grounded in the relevant philosophical and scientific literatures, Varner is as precise in analysis as he is wide-ranging in scope. His writing is clear and rigorous, and he explains philosophical nuances with extraordinary (...) economy of expression. Never one to add an unnecessary clause to a sentence, Varner nonetheless constructs a formidable edifice while always dealing fairly with the authors he criticizes. His explication of the properties and moral status of what he calls near-persons is a crucial addition to the discussion of personhood initiated by Parfit in Reasons and Persons and subsequently applied to animals by McMahan in The Ethics of Killing. The comparison to McMahan is intentional for, to my mind, Varner vies with him as the most important animal ethicist since Singer and Regan. (shrink)

The theory of knowledge in early twentieth-century Anglo American philosophy was oriented toward phenomenally described cognition. There was a healthy respect for the mind-body problem, which meant that phenomena in both the mental and physical domains were taken seriously. Bertrand Russell's developing position on sense-data and momentary particulars drew upon, and ultimately became like, the neutral monism of Ernst Mach and William James. Due to a more recent behaviorist and physicalist inspired "fear of the mental", this development has been down-played (...) in historical work on early analytic philosophy. Such neglect assumes that the "linguistic turn" is a proper and permanent effect of twentieth-century philosophy, an assumption that distorts early analytic historiography, and begs a substantive philosophical question about thought and cognition.

Should people include beef in their diet? This chapter argues that the answer is “no” by reviewing what is known and not known about the presence in cattle of three psychological traits: pain, desire, and self-consciousness. On the basis of behavioral and neuroanatomical evidence, the chapter argues that cattle are sentient beings who have things they want to do in the proximal future, but they are not self-conscious. The piece rebuts three important objections: that cattle have injury information but not (...) pain; that cattle have goal-directed behavior but not desire; and that the absence of evidence for bovine self-consciousness should not be taken as evidence that cattle lack self-consciousness. In sum, what is known about cattle cognition shifts the moral burden of proof on to the beef eaters. (shrink)

There is a strong philosophical intuition that direct study of the brain can and will constrain the development of psychological theory. When this intuition is tested against case studies on the neurophysiology and psychology of perception and memory, it turns out that psychology has led the way toward knowledge of neurophysiology. An abstract argument is developed to show that psychology can and must lead the way in neuroscientific study of mental function. The opposing intuition is based on mainly weak arguments (...) about the fundamentality or objectivity of physics or physiology in relation to psychology. -/- Philosophy of Science, Vol. 67, Supplement.

In this essay, I want to explore one of the most ironic episodes in the history of propaganda, the attempt by various federal agencies to moderate American WWII anti-Japanese propaganda films. My texts will be four films, two produced by the military, and two by Hollywood: December 7th (1943), directed by Gregg Toland and revised by John Ford; Air Force (1943), directed Howard Hawks; Know Your Enemy: Japan (1945), directed by Frank Capra; and Betrayal for the East (1945), directed by (...) William Berke. As all of these films are readily available on YouTube, I will be brief in my description of them. Instead, I will focus on how they served to intensify racial hatred of Japanese in general and Japanese-Americans in particular, and how the federal government tried to control that propaganda—but was limited by its own policies regarding Japanese-Americans.

During the 1630s Descartes recognized that he could not expect all legitimate claims in natural science to meet the standard of absolute certainty. The realization resulted from a change in his physics, which itself arose not through methodological reflections, but through developments in his substantive metaphysical doctrines. Descartes discovered the metaphysical foundations of his physics in 1629-30; as a consequence, the style of explanation employed in his physical writings changed. His early methodological conceptions, as preserved in the Rules and sketched (...) in Part Two of the Discourse, pertained primarily to his early work in optics. By the early 1630s, Descartes was concerned with new methodological problems pertaining to the postulation of micro-mechanisms. Recognition of the need to employ a method of hypothesis led him to lower the standard of certainty required of particular explanations in his mature physics. (shrink)

The term ‘propaganda’ is normally taken in the pejorative sense of deceitful messaging. Propaganda is considered dubious if it is produced by a government agency, especially by a ministry of war or propaganda. In this article, I apply the theory of propaganda I sketched in a prior piece in these pages, under which propaganda is simply messaging intended to persuade others to do something or to support something. Under this theory, propaganda is reasonable if but only if it is evidence-based, (...) truthful, broadly logical, not coercive, targeted at mentally competent adults, and transparent—meaning that the audience should be aware that the message is intended to persuade them to do or support something. I then examine three WWII-era government propaganda films, one—A Defeated People (1946)—produced by the British military, and two—The Negro Soldier (1944) and Teamwork (1947)—produced by the American military. I explain first why I chose these particular films. I then analyze these films in some detail and show that while they were not perfectly rational, they all effectively conveyed the persuasive message that the respective militaries wanted to convey. And they did this by meeting all of the criteria for propaganda to be rational. (shrink)

In this article, I set forth a theory of propaganda explaining what it is, how it relates to marketing, and the nature and types of ideology. I discuss the criteria by which we can judge the rationality or deceitfulness of propaganda. I defend the view that while propaganda can be perfectly rational, it rarely is, and I explain why that is the case. I finish by explaining why the question of the rationality or deceitfulness of propaganda is different from the (...) question of the morality of propaganda. I give two quick examples of how an ethicist might argue that deceptive propaganda might be ethical to use, and perfectly rational propaganda might be immoral to use. I conclude with the notion that the question of the ethics of marketing and propaganda is complex, and should be handled in a separate paper. (shrink)

The infinite judgement has long been forgotten and yet, as I am about to demonstrate, it may be urgent to revive it for its critical and productive potential. An infinite judgement is neither analytic nor synthetic; it does not produce logical truths, nor true representations, but it establishes the genetic conditions of real objects and the concepts appropriate to them. It is through infinite judgements that we reach the principle of transcendental logic, in the depths of which all reality can (...) emerge in its material and sensible singularity, making possible all generalization and formal abstraction.

Given certain standard assumptions-that particular sentences are meaningful, for example, and do genuinely self-attribute their own falsity-the paradoxes appear to show intriguing patterns of generally unstable semantic behavior. In what follows we want to concentrate on those patterns themselves: the pattern of the Liar, for example, which if assumed either true or false appears to oscillate endlessly between truth and falsehood.

The contention discussed here, is that one might be able to get around the puzzle contained in the results of Kim and Chan:— That a quantity of inertial mass is effectively lost, (a so called non-classical-rotational inertia NCRI,) but that being a “supersolid” there is no path for the normal fraction to slip past the 1 – 2 % supersolid fraction, which (it is supposed) remains stationary within the annulus. As a solution we argue that the effective loss of inertial (...) mass might be a real loss of inertial mass– that it might be intrinsic to a supersolid or superfluid “pool,” (a portion which has gone supersolid or superfluid.) In this way the puzzle would be resolved because the normal part and the supersolid part do not need to slip past each other in order to produce the experimental results. (shrink)

Experimenters claim some nonhuman mammals have metacognition. If correct, the results indicate some animal minds are more complex than ordinarily presumed. However, some philosophers argue for a deflationary reading of metacognition experiments, suggesting that the results can be explained in first-order terms. We agree with the deflationary interpretation of the data but we argue that the metacognition research forces the need to recognize a heretofore underappreciated feature in the theory of animal minds, which we call Unity. The disparate mental states (...) of an animal must be unified if deflationary accounts of metacognition are to hold and untoward implications avoided. Furthermore, once Unity is acknowledged, the deflationary interpretation of the experiments reveals an elevated moral standing for the nonhumans in question. (shrink)

Hume is an experimental philosopher who attempts to understand why we think, feel, and act as we do. But how should we evaluate the adequacy of his proposals? This chapter examines Hume’s account from the perspective of interdisciplinary work in cognitive science.

Hume maintains that the boundaries of morality are widely drawn in everyday life. We routinely blame characters for traits that we find disgusting, on this account, as well as those which we perceive as being harmful. Contemporary moral psychology provides further evidence that human beings have a natural tendency to moralize traits that produce feelings of repugnance. But recent work also demonstrates a significant amount of individual variation in our sensitivities to disgust. We have sufficient reason to bracket this emotion, (...) therefore, when adopting the general point of view: if we allow idiosyncratic affective responses to shape our fully considered moral judgments, we could no longer reasonably expect spectators with different sensitivities to agree with us. (shrink)

Does Carnap’s treatment of philosophical questions about existence, such as “Are there numbers?” and “Are there physical objects?”, depend on his analytic–synthetic distinction? If so, in what way? I answer these questions by clarifying, defending, and developing the reading of Carnap’s paper “Empiricism, Semantics, and Ontology” that W. V. Quine proposes, with little justification or explanation, in his paper “On Carnap’s Views on Ontology”. The primary methodological value of studying Quine’s reading of “Empiricism, Semantics, and Ontology” is that it prompts (...) us to look for, and helps us to see the significance of, passages by Carnap that reveal the logical foundations of his views on ontology. Guided in this way by Quine’s reading, I show that (1) in “Empiricism, Semantics, and Ontology” Carnap’s preferred treatment of philosophical questions relies on paraphrasing them so that their answers are immediately obvious elementary logical truths, and are therefore, by his standards, trivially analytic; and (2) in its most general form, Carnap’s treatment of philosophical questions about existence depends on his controversial view that the analytic truths of a language L may include sentences that are not elementary logical truths, but that are nevertheless, by Carnap’s standards, analytic-in-L simply because we have stipulated that they are to be among the “meaning postulates” of L.

In ‘A Dialogue’, Hume offers an important reply to the moral skeptic. Skeptics traditionally point to instances of moral diversity in support of the claim that our core values are fixed by enculturation. Hume argues that the skeptic exaggerates the amount of variation in moral codes, however, and fails to adopt an indulgent stance toward attitudes different from ours. Hume proposes a charitable interpretation of moral disagreement, moreover, which traces it back to shared principles of human nature. Contemporary philosophers attempt (...) to locate examples of moral variability that cannot be accommodated in this way. But they are no more successful than their predecessors. Moral skeptics have not found a single case of moral diversity that is resistant to the Humean strategy. (shrink)

We argue on consequentialist grounds for the transfer of Sandai, an orangutan, to an orangutan sanctuary. First, we show that satisfying his interest in being transferred brings far greater value than the value achieved by keeping him confined. Second, we show that he has the capacities sufficient for personhood. Third, we show that all persons have a right to relative liberty insofar as they have interests they can exercise only under conditions of relative liberty. Fourth, we show that individuals need (...) not be able to assume social obligations and duties in order to be rights holders. -/- Our argument reflects commitments, as we say, to consequentialist reasoning about moral problems. However, we note that influential representatives of the other dominant ethical traditions—the deontological and Aristotelian traditions—reach our conclusion, too. It makes no difference, in this instance, which ethical theory one adopts. Under all of them, Sandai is a person with an interest in relative liberty entitled to habeas corpus protection. (shrink)

Should the law recognize an elephant’s right to be released from solitary confinement? The New York State Court of Appeals—the highest court in the State of New York—will consider this question on May 18. At issue is an Asian elephant named Happy. But happy she is not. Every human being has a right to bodily liberty because they have strong interests that this right protects. Since Happy has the same strong interests, the Court should recognize Happy’s right to be freed (...) from solitary confinement. (shrink)

A properly programmed artificially intelligent agent may eventually have one duty, the duty to satisfice expected welfare. We explain this claim and defend it against objections.

Let us call the deliberate modification of an individual’s genome to improve it or its progeny intentional genetic enhancement. Governments are almost certain to require that any proposed intentional genetic enhancement of a human (IGEH) be tested first on (what researchers call) animal “models.” Intentional genetic enhancement of animals (IGEA), then, is an ambiguous concept because it could mean one of two very different things: an enhancement made for the sake of the animal’s own welfare, or an enhancement made for (...) the sake of satisfying a human desire. In either case, experimental procedures are likely to entail substantial risks to the experimental animals. What rules should govern IGEA? I criticize the abolitionist conclusions of animal rightists—that no IGEA should be permitted—and I criticize the permissive conclusions of speciesists—that all IGEA should be permitted. Both views are unsatisfying. I suggest instead that current animal welfare law provides a defensible platform on which to begin building ethically justifiable policy in this area. (shrink)

In this review essay, I review in detail Abram de Swann's fine new book, The Killing Compartments. The book is a theoretical analysis of the varieties and causes of genocides and other mass asymmetrical killing campaigns. I then suggest several criticisms of his analysis.

In the past 60 years or so, the philosophical subject of artistic expression has generally been handled as an inquiry into the artistic expression of emotion. In my view this has led to a distortion of the relevant territory, to the artistic expression of feeling’s too often being overlooked. I explicate the emotion-feeling distinction in modern terms, and urge that the expression of feeling is too central to be waived off as outside the proper philosophical subject of artistic expression. Restricting (...) the discussion to the art of painting, I sketch a partial psychological model for the exrtistic expression of feelipression of feeling. Although the feeling-emotion contrast is seldom made clear in their writings, I stress that many, or even most of the eminent pre-1960’s voices in aesthetics and art criticism—Croce, Dewey, Langer, Bosanquet, Berenson and others—would more or less agree that feeling is no less important for expression than emotion, and indeed can be interpreted as anticipating many points that I set forth.

In December 2013, the Nonhuman Rights Project (NhRP) filed a petition for a common law writ of habeas corpus in the New York State Supreme Court on behalf of Tommy, a chimpanzee living alone in a cage in a shed in rural New York (Barlow, 2017). Under animal welfare laws, Tommy’s owners, the Laverys, were doing nothing illegal by keeping him in those conditions. Nonetheless, the NhRP argued that given the cognitive, social, and emotional capacities of chimpanzees, Tommy’s confinement constituted (...) a profound wrong that demanded remedy by the courts. Soon thereafter, the NhRP filed habeas corpus petitions on behalf of Kiko, another chimpanzee housed alone in Niagara Falls, and Hercules and Leo, two chimpanzees held in research facilities at Stony Brook University. Thus began the legal struggle to move these chimpanzees from captivity to a sanctuary, an effort that has led the NhRP to argue in multiple courts before multiple judges. The central point of contention has been whether Tommy, Kiko, Hercules, and Leo have legal rights. To date, no judge has been willing to issue a writ of habeas corpus on their behalf. Such a ruling would mean that these chimpanzees have rights that confinement might violate. Instead, the judges have argued that chimpanzees cannot be bearers of legal rights because they are not, and cannot be persons. In this book we argue that chimpanzees are persons because they are autonomous. (shrink)

According to the reading offered here, Descartes' use of the meditative mode of writing was not a mere rhetorical device to win an audience accustomed to the spiritual retreat. His choice of the literary form of the spiritual exercise was consonant with, if not determined by, his theory of the mind and of the basis of human knowledge. Since Descartes' conception of knowledge implied the priority of the intellect over the senses, and indeed the priority of an intellect operating independently (...) of the senses, and since, in Descartes' view, the untutored individual was likely to be nearly wholly immersed in the senses, a procedure was needed for freeing the intellect from sensory domination so that the truth might be seen. Hence, the cognitive exercises of the Meditations, modeled not on the sense- and imagination-based exercises of Ignatius of Loyola, but on the Augustinian procedure of turning away from the senses and imagination to perceive the unpicturable with the fleshless eye of the mind. In accordance with this reading, the function of Descartes' skeptical arguments is not to introduce skepticism so that it can be defeated but to aid the meditator in withdrawing the mind from the senses in order to attend to truths of the pure intellect. These truths then offer the basis for a new natural philosophy, including a new theory of the senses. (shrink)

Crump et al.’s contribution to assessing whether decapods feel pain raises an important question: Is pain distributed unevenly across the order? The case for pain appears stronger in Pleocyemata than in Dendrobranchiata. Some studies report pain avoidance behaviors in Dendrobranchiata (Penaeidae) shrimp, but further studies are needed to determine whether the chemicals used are acting as analgesics to relieve pain, or as soporifics to reduce overall alertness. If the latter, the most farmed shrimp species may not require the same level (...) of protection as crabs, crayfish, and lobsters. (shrink)

In the voluminous literature on the subject of bovine growth hormone (bGH) we have yet to find an attempt to frame the issue in specifically moral terms or to address systematically its ethical implications. I argue that there are two moral objections to the technology: its treatment of animals, and its dislocating effects on farmers. There are agricultural biotechnologies that deserve funding and support. bGH is not one of them.

In this chapter, Gary Comstock considers whether it is ethically justified to pursue genetically modified ( GM) crops and foods. He first considers intrinsic objections to GM crops that allege that the process of making GMOs is objectionable in itself. He argues that there is no justifiable basis for the objections- i.e. GM crops are not intrinsically ethically problematic. He then considers extrinsic objections to GM crops, including objections based on the precautionary principle, which focus on the potential harms (...) that may result from the adoption of GM organisms. He argues that these concerns have some merit. However, they do not justify giving up GM crops altogether. Instead, they require that GM crops be developed carefully and with appropriate oversight. Comstock then presents the positive case for GM crops that he endorses. It is based on three considerations: (i) the right of people to choose to adopt GM technology; (ii) the balance of likely benefits over harms to consumers and the environment from GM technology; and (iii) the wisdom of encouraging discovery, innovation, and careful regulation of GM technology.
