What implications, if any, does evolutionary biology have for metaethics? Many believe that our evolutionary background supports a deflationary metaethics, providing a basis at least for debunking ethical realism. Some arguments for this conclusion appeal to claims about the etiology of the mental capacities we employ in ethical judgment, while others appeal to the etiology of the content of our moral beliefs. In both cases the debunkers’ claim is that the causal roles played by evolutionary factors raise deep epistemic problems (...) for realism: if ethical truths are objective or independent of our evaluative attitudes, as realists maintain, then we lose our justification for our ethical beliefs once we become aware of the evolutionary shaping of our ethical capacities or beliefs, which would not have disposed us reliably to track independent ethical truths; realism, they claim, thus saddles us with ethical skepticism. I distinguish and spell out various evolutionary debunking arguments along these lines and argue that they all fail: the capacity etiology argument fails to raise any special or serious problem for realism, and the content etiology arguments all rely on strong explanatory claims about our moral beliefs that are simply not supported by the science unless it is supplemented by philosophical claims that just beg the question against realism from the start. While the various debunking arguments do bring out some interesting commitments of ethical realism, and even raise some good challenges as realists develop positive moral epistemologies, they fall far short of their debunking ambitions.

Symbols in computer programs are not necessarily isomorphic in form or capability to neural processes. Representations in our models are stored descriptions of the world and human behavior, created by a human interpreter; representations in the brain are neither immutable forms nor encoded in some language. Although the term " symbol " can be usefully applied to describe words, smoke signals, neural maps, and graphic icons, a science of symbol processing requires distinguishing between the structural, developmental, and interactive nature of (...) different forms of representing.

The ‘default mode’ network refers to cortical areas that are active in the absence of goal-directed activity. In previous studies, decreased activity in the ‘default mode’ has always been associated with increased activation in task-relevant areas. We show that the induction of hypnosis can reduce anterior default mode activity during rest without increasing activity in other cortical regions. We assessed brain activation patterns of high and low suggestible people while resting in the fMRI scanner and while engaged in visual tasks, (...) in and out of hypnosis. High suggestible participants in hypnosis showed decreased brain activity in the anterior parts of the default mode circuit. In low suggestible people, hypnotic induction produced no detectable changes in these regions, but instead deactivated areas involved in alertness. The findings indicate that hypnotic induction creates a distinctive and unique pattern of brain activation in highly suggestible subjects. (shrink)

A brief introduction to Meinong, his theory of objects, and modern interpretations of it. Sections include: The Theory of Objects, Castañeda's Theory of Guises, Parsons,'s Theory of Nonexistent Objects, Rapaport's Theory of Meinongian Objects, Routley's Theory of Items.

This paper argues that we ought to conceive of the Dark Energy problem—the question of how to account for observational data, naturally interpreted as accelerated expansion of the universe—as a crisis of underdetermined pursuit-worthiness. Not only are the various approaches to the Dark Energy problem evidentially underdetermined; at present, no compelling reasons single out any of them as more likely to be true than the other. More vexingly for working scientists, none of the approaches stands out as uncontroversially preferable over (...) its rivals in terms of its rationally warranted promise, i.e. the reasons to further work on, explore, and develop it. We demonstrate this claim by applying a Peircean economic model of pursuit-worthiness in terms of a cognitive cost/benefit estimate—with the instantiation of theory virtues as key indicators of cognitive gains—to the four main Dark Energy proposals (the cosmological constant approach, modified gravity, quintessence, and inhomogeneous cosmologies). According to our analysis, these approaches do not admit of an unambiguous, or uncontroversial, ranking with respect to which ansatz deserves distinguished attention and research efforts. The overall methodological counsel that our analysis underwrites recommends a pragmatic double research strategy forward: to encourage and foster theory pluralism and the search for tests—with the goal of enhancing the testability of the \(\Lambda \) CDM model and “testing it to destruction".

I argue that George Nakhnikian's analysis of the logic of cogito propositions (roughly, Descartes's 'cogito' and 'sum') is incomplete. The incompleteness is rectified by showing that disjunctions of cogito propositions with contingent, non-cogito propositions satisfy conditions of incorrigibility, self-certifyingness, and pragmatic consistency; hence, they belong to the class of propositions with whose help a complete characterization of cogito propositions is made possible.

There are many branches of philosophy called “the philosophy of X,” where X = disciplines ranging from history to physics. The philosophy of artificial intelligence has a long history, and there are many courses and texts with that title. Surprisingly, the philosophy of computer science is not nearly as well-developed. This article proposes topics that might constitute the philosophy of computer science and describes a course covering those topics, along with suggested readings and assignments.

La resiliencia es muchas veces definida como un proceso que permite a los seres humanos soportar un golpe de la vida y convertirlo en algo positivo. Este artículo demuestra que es necesario ir más lejos: 1. la resiliencia debe ser la genealogía de la emergencia de los valores impuestos (en el sentido de F. Nietzsche y M. Foucault) que muchas veces nos hacen sufrir. No hay que considerar el resentimiento y la venganza, como formas de emancipación de la tristeza, ya (...) que nos convierten en esclavos libres como en el caso de la teodicea. 2. El resiliente necesita recuperar la facultad de juzgar perdida por la acción del sufrimiento y la confusión, para así reelaborar y reevaluar lo sucedido (J. Poulain), y salir del tenebroso camino que conduce hacia un falso self (D. Winnicott). La teoría del apego de J. Bowlby es indispensable para logar dicha tarea, puesto que no somos nadie sin la base de seguridad que nos dan los demás. (shrink)

Critical Review of Searle's Minds, Brains and Science.

This essay examines the role of non-existent objects in "epistemological ontology" — the study of the entities that make thinking possible. An earlier revision of Meinong's Theory of Objects is reviewed, Meinong's notions of Quasisein and Außersein are discussed, and a theory of Meinongian objects as "combinatorially possible" entities is presented.

We believe that clinical ethics consultants (CECs) should offer advice, options, and recommendations to attending physicians and their teams. In their article in this issue of The Journal of Clinical Ethics, however, Kornfeld and Prager give CECs a somewhat different role. The CEC they describe may at times be more aptly understood as a medical interventionist who appropriates the roles of the attending physician and the medical team than as a traditional CEC. In these remarks, we distinguish the role of (...) the CEC from that of the physician, in contrast to some of these authors’ recommendations, which confuse the two roles. (shrink)

The author identifies the structure of Sharon Street's skeptical challenge to non-naturalist, normative epistemic realism as an argument that NNER is liable to reliability defeat and then argues that Street's argument fails, because it itself is subject to reliability defeat. As the author reconstructs Street's argument, it is an argument that the normative epistemic judgments of the realist could only be probabilistically sensitive to normative epistemic truths by sheer chance. The author then recaps Street's own naturalist translation of normative epistemic (...) judgments into purely descriptive, contingent probability statements, and argues that, on her own terms, the reasoning that leads her to rationally believe in evolutionary theory could only be probabilistically sensitive to the relevant purely descriptive, contingent probabilities by sheer chance. The author's argument is addressed to Street, but it applies to all evolutionary naturalist accounts of epistemic rationality. The author explains how his argument differs from Plantinga's Evolutionary Argument Against Naturalism and shows how it avoids the objections to Plantinga's EAAN. The author closes with the outline of an explanation of how evolution could have made human reasoning probabilistically sensitive to metaphysically necessary normative epistemic standards, even though those standards did not exert and, indeed, could not have exerted any kind of causal influence on the evolutionary process.

Despite widespread agreement that we have moral responsibilities to future generations, many are reluctant to frame the issues in terms of justice and rights.There are indeed philosophical challenges here, particularly concerning nonoverlapping generations. They can, however, be met. For example, talk of justiceand rights for future generations in connection with climate change is both appropriate and important, although it requires revising some common theoreticalassumptions about the nature of justice and rights. We can, in fact, be bound by the rights of (...) future people, despite the “non-identity problem,” and the force of these rights cannot be diluted by “discounting” future costs. Moreover, a rights-based approach provides an effective answer to political arguments against taking mandatory measures to curb greenhouse gas emissions when these are unpopular with a democratic populace.

The author uses a series of examples to illustrate two versions of a new, nonprobabilist principle of epistemic rationality, the special and general versions of the metacognitive, expected relative frequency principle. These are used to explain the rationality of revisions to an agent’s degrees of confidence in propositions based on evidence of the reliability or unreliability of the cognitive processes responsible for them—especially reductions in confidence assignments to propositions antecedently regarded as certain—including certainty-reductions to instances of the law of excluded (...) middle or the law of noncontradiction in logic or certainty-reductions to the certainties of probabilist epistemology. The author proposes special and general versions of the MERF principle and uses them to explain the examples, including the reasoning that would lead to thoroughgoing fallibilism—that is, to a state of being certain of nothing. The author responds to the main defenses of probabilism: Dutch Book arguments, Joyce’s potential accuracy defense, and the potential calibration defenses of Shimony and van Fraassen by showing that, even though they do not satisfy the probability axioms, degrees of belief that satisfy the MERF principle minimize expected inaccuracy in Joyce’s sense; they can be externally calibrated in Shimony and van Fraassen’s sense; and they can serve as a basis for rational betting, unlike probabilist degrees of belief, which, in many cases, human beings have no rational way of ascertaining. The author also uses the MERF principle to subsume the various epistemic akrasia principles in the literature. Finally, the author responds to Titelbaum’s argument that epistemic akrasia principles require that we be certain of some epistemological beliefs, if we are rational. (shrink)

Knowledge engineers once viewed themselves as priests; they received "The Word" from experts above, added nothing to the content, but codified it accurately into written rules, and passed it down to ordinary folks as commandments to live by.

In lieu of an abstract, here is a brief excerpt of the content:IntroductionWilliam J. ConnellOne of the more unusual works in the corpus of the Italian humanist Lorenzo Valla is the Oratio in principio sui studii, on the relation between Latin letters and the Christian faith. The speech was written and delivered in October 1455, toward the end of Valla’s life, as a lecture to inaugurate the academic year at the University of Rome where he had held the chair in (...) rhetoric since 1450. It was traditional at Rome to hold such an address each year not only to encourage the assembled students and faculty in their studies but also to thank the papacy for its support of the university, the Studium Urbis. For this reason Valla’s speech ends with customary words praising Pope Calixtus III for having increased the stipends of the lecturers in the university, even though, notwithstanding some remarkable kindnesses to Valla himself, Calixtus’s reputation was not that of a friend to scholarship. Valla’s Schoolyear Inaugural was not lengthy: it can only have lasted fifteen minutes. Nor is there indication that anyone was displeased with it. In fact, that is precisely what is oddest about the Inaugural, for throughout his career Valla had shown himself to be the sort of person who seized on such occasions to make polemical arguments. We read the speech—and it is possible that his audience also listened to it this way—expecting with each step that Valla will let fly a critical or unorthodox statement, but that never happens. 1Beginning with his earliest formal work, a comparison of Cicero and Quintilian written in 1428 and now lost, in which the humanist argued against Cicero on behalf of Quintilian, Valla seemed to delight in challenging established authorities. 2 His next important work, an attack on Bartolus of [End Page 1] Sassoferrato and the scholastic method of contemporary jurists, resulted in his forced departure from the University of Pavia. 3 A continuing combativeness is illustrated in subsequent writings, reaching an apogee in the work on the Donation. Even when Valla was developing another writer’s idea, he had a consistent way of pushing the argument to a daring extreme. This, as Riccardo Fubini argues below, is what Valla did in the De donatione, a work Fubini suggests relied more heavily on Nicholas of Cusa’s De concordantia catholica than hitherto realized, but written to promote an agenda far more radical than that of Cusanus. One of the surest indications of Valla’s brilliance as a polemicist is the fact that seventy years after his death humanists of the caliber of Agostino Steuco, the subject of Ronald K. Delph’s essay in this number, were still eager to take up cudgels against him.Valla paid a price for initiating so many disputes. In 1444, when he was called before the Inquisition in Naples after the attack on the Donation of Constantine, Valla was made to answer charges against not only that work, but also against the De vero bono for its Epicureanism, the De libero arbitrio for its determinism, the De professione religiosorum for its criticism of religious orders, and the Repastinatio totius dialectice et philosophie for various unorthodox statements, especially concerning the Trinity. This last work was the humanist’s most ambitious project, and he seems to have been aware of its explosive quality, since he alluded to a “peril to his life” should it be published. 4The 1455 Schoolyear Inaugural shows no trace of the risks that Valla took in his other writings, of his polemical temperament, or of his past disagreements with the Church. With style and vigor the speech argues that the Church deserves great thanks and praise for having ensured the survival [End Page 2] of Latin letters after the collapse of the Empire. This may seem a notable change of heart in the author who had written the oration On the Falsely Believed and Forged Donation of Constantin—a text which always seems to be lurking in the background of the Inaugural but which finds no explicit reference there. Given the proximity of Valla’s argument to the well-worn medieval theme of the translatio studii, his argument could hardly have been... (shrink)

The increasing role played by medical ethicists in the clinical setting both as teachers and consultants has brought with it a demand for new methodologies that speak more precisely to the multiple problems encountered in actual attempts at case resolution. Some of these moves have to do with a revival of the truly classic case study approach to ethics, casuistry. This approach is anchored in the revelatory text of Jonsen and Toulmin, TheAbuseofCasuistry. A fine example of this methodology is an (...) article in TheJournalofClinicalEthics, Conjoined to this approach is a renewed interest in virtue ethics. The groundwork for this was laid by MacIntyre's masterful history of its demise in AfterVirtue. A clear and concise application of this ancient but always new approach is given in Pellegrino and Thomasma's book TheVirtuesinMedicalPractice. This way of doing ethics is particularly congenial to the practice of healthcare ethics in that it understands that virtue is just a rather fancy name for a good habit or skill. Since the practice of clinical medicine is quintessentially the learning and application of a range of often highly complex patterns of professional abilities and skills, a virtue ethics approach will allow for the concomitant development of a whole set of ethical skills. But both casuistry and virtue ethics may well be seen to be operative in a larger context now known as narrative ethics. (shrink)

John H. Evans’s views on the multiple roles of healthcare ethics consultants are based on his claim that bioethics is a “distinct profession” that has a “system of abstract knowledge.” This response to Professor Evans disputes both of his claims. It is argued that clinical ethicists are consultants but not professionals. Their roles as consultants require more than one abstract form of knowledge (principlism). Instead, clinical ethicists rely upon a variety of ethical perspectives and other skills to help resolve conflicts (...) and facilitate healthcare decisions and policy making, whether it is in clinical, research, policy, or organizational contexts. The credibility and effectiveness of clinical ethicists depend upon their knowledge of ethics, their practical experience, and personal abilities, not one form of abstract knowledge. (shrink)

The claim that glycogen contains protein was first made exactly 100 years ago and has been the subject of contention ever since. It has now been established that rabbit‐muscle glycogen contains a covalently bound protein of Mr 37,000, present in equimolar proportion to glycogen. The protein, named glycogenin, is joined to muscle glycogen via a novel linkage involving the hydroxyl group of tyrosine, a fact of possible significance in the light of insulin's message being transmitted by tyrosine phosphorylation. The protein (...) is seen as the biogenetic precursor of glycogen. Its existence suggests an additional mode of regulation of glycogen metabolism since the amount, turnover and cellular location of glycogenin will influence the corresponding parameters for glycogen. A protein “primer” is suggested for the biogenesis of storage polysaccharides in general. (shrink)

The idea of role‐playing makes some people nervous – even some people who play role‐playing games (RPGs). So the idea of immersion is central to understanding how Dungeons Dragons and other aspects of participatory culture work. Phenomenology is a kind of “philosophy of mind” associated with the works of twentieth‐century philosophers Edmund Husserl, Martin Heidegger, Jean‐Paul Sartre, and Maurice Merleau‐Ponty, among others. The domain of phenomenology encompasses the entire range of experiences in the world, paying attention to what Husserl called (...) “intentionality,” or how our consciousness is directed toward particular objects in the world. The fact that this is presented as an atypical approach to play, or at least one that requires some effort, invites us to ask about typical modes of play if visualization of in‐game events is not that mode. This chapter concluded by scratch the surface of a complete phenomenological description of role‐playing. (shrink)

Persons who experience severe brain injury often suffer significant disorders of consciousness. Anoxic injuries from cardiac arrest or strokes and traumatic injuries from falls, vehicular crashes, or assaults can result in several conditions in which patients lose or have diminished consciousness for an extended period of time. Two such conditions that create considerable public confusion and controversy are the vegetative state and the minimally conscious state. Although these conditions have generated significant medical and academic research, the general public and policymakers (...) are often confused about the nature of VS and MCS. The most recent evidence for this confusion is the acrimonious public debate, the extensive media coverage, the prolonged litigation, and the attempts of various governmental officials to intervene in dealing with the plight of Terri Schiavo.

My interest is to examine the nature of mind in relation to value, for I suspect that the neglect by the psychologist of the true status of value has deterred his work in two respects: first, that it has prevented a genuine theory of mind's being arrived at, and secondly that it has prevented him in his clinical work from achieving for the individual the fuller expression of mind or self that makes for satisfaction or happiness.

Alexius Meinong developed a notion of defective objects in order to account for various logical and psychological paradoxes. The notion is of historical interest, since it presages recent work on the logical paradoxes by Herzberger and Kripke. But it fails to do the job it was designed for. However, a technique implicit in Meinong's investigation is more successful and can be adapted to resolve a similar paradox discovered by Romane Clark in a revised version of Meinong's Theory of Objects due (...) to Rapaport. One family of paradoxes remains, but it is argued that they are unavoidable and relatively harmless. (shrink)

During the late-nineteenth and twentieth centuries interpretations of the British Industrial Revolution became embedded within debates over competing systems of political economy, primarily liberal democracy (free trade) versus socialism (state regulation). At the heart of this contest was also the question of epistemology. A picture emerged of the Industrial Revolution that reflected such contrasting perspectives; for those with a Western liberal bent Britain industrialized first due to a weak state, an emphasis upon individual liberty, the right institutions and culture of (...) creativity born of free minds and free markets. At the heart of this was the emergence of science; objectivity and Western democracy became a key cornerstone of this perspective. This view was first especially spearheaded by the Austrian economists Ludwig von Mises (1881–1973) and, slightly later, Friedrich A. Hayek (1899–1992). The debate subsequently became particularly fierce during the Cold War, and since the fall of the Berlin Wall the role of the state and protectionism within Britain’s industrial history has greatly diminished. Indeed today’s dominant historiography continues to erase Britain’s actual industrial experience and, instead, reflect entrenched liberal and neoliberal prescriptions. A major axiom of this ideological viewpoint is the centrality of science and its history. (shrink)
