This article provides a spatial analysis of the conceptual framework of fluid dynamics during the nineteenth century, focusing on the transition from the Euler equation to the Navier–Stokes equation. A dynamic version of Peter Gärdenfors's theory of conceptual spaces is applied which distinguishes changes of five types: addition and deletion of special laws; change of metric; change in importance; change in separability; addition and deletion of dimensions. The case instantiates all types but the deletion of dimensions. We also provide a (...) new view upon limiting case reduction at the conceptual level that clarifies the relation between the predecessor and successor conceptual framework. The nineteenth-century development of fluid dynamics is argued to be an instance of normal science development. (shrink)

Frames, i.e., recursive attribute-value structures, are a general format for the decomposition of lexical concepts. Attributes assign unique values to objects and thus describe functional relations. Concepts can be classified into four groups: sortal, individual, relational and functional concepts. The classification is reflected by different grammatical roles of the corresponding nouns. The paper aims at a cognitively adequate decomposition, particularly, of sortal concepts by means of frames. Using typed feature structures, an explicit formalism for the characterization of cognitive frames is (...) developed. The frame model can be extended to account for typicality effects. Applying the paradigm of object-related neural synchronization, furthermore, a biologically motivated model for the cortical implementation of frames is developed. Cortically distributed synchronization patterns may be regarded as the fingerprints of concepts. (shrink)

Body checking, characterized by the repeated visual or physical inspection of particular parts of one’s own body (e.g. thighs, waist, or upper arms) is one of the most prominent behaviors associated with eating disorders, particularly Anorexia Nervosa (AN). In this paper, we explore the explanatory potential of the Recalcitrant Fear Model of AN (RFM) in relation to body checking. We argue that RFM, when combined with certain plausible auxiliary hypotheses about the cognitive and epistemic roles of emotions, is able to (...) explain key characteristics of body checking, including how body checking behavior becomes habitual and compulsive.

In a recent paper in this journal, Carter and Peterson raise two distinctly epistemological puzzles that arise for anyone aspiring to defend the precautionary principle. The first puzzle trades on an application of epistemic contextualism to the precautionary principle; the second puzzle concerns the compatibility of the precautionary principle with the de minimis rule. In this note, I argue that neither puzzle should worry defenders of the precautionary principle. The first puzzle can be shown to be an instance of the (...) familiar but conceptually harmless challenge of adjudicating between relevant interests to reach assessments of threats when applying the precautionary principle. The second puzzle can be shown to rely on a subtle but crucial misrepresentation of the relevant probabilities at play when applying the precautionary principle. (shrink)

Standard epistemology takes it for granted that there is a special kind of value: epistemic value. This claim does not seem to sit well with act utilitarianism, however, since it holds that only welfare is of real value. I first develop a particularly utilitarian sense of “epistemic value”, according to which it is closely analogous to the nature of financial value. I then demonstrate the promise this approach has for two current puzzles in the intersection of epistemology and value theory: (...) first, the problem of why knowledge is better than mere true belief, and second, the relation between epistemic justification and responsibility.

Inquiry is an aim-directed activity, and as such governed by instrumental normativity. If you have reason to figure out a question, you have reason to take means to figuring it out. Beliefs are governed by epistemic normativity. On a certain pervasive understanding, this means that you are permitted – maybe required – to believe what you have sufficient evidence for. The norms of inquiry and epistemic norms both govern us as agents in pursuit of knowledge and understanding, and, on the (...) surface, they do so in harmony. Recently, however, Jane Friedman (2020) has pointed out that they are in tension with each other. In this paper, I aim to resolve this tension by showing that reasons for acts of inquiry – zetetic reasons – and epistemic reasons for belief can both be understood as flowing from the same general normative principle: the transmission principle for instrumental reasons. The resulting account is a version of epistemic instrumentalism that offers an attractive unity between zetetic and epistemic normativity. (shrink)

For at least three decades, philosophers have argued that general causation and causal explanation are contrastive in nature. When we seek a causal explanation of some particular event, we are usually interested in knowing why that event happened rather than some other specified event. And general causal claims, which state that certain event types cause certain other event types, seem to make sense only if appropriate contrasts to the types of events acting as cause and effect are specified. In recent (...) years, philosophers have extended the contrastive theory of causation to encompass singular causation as well. In this article, I argue that this extension of the theory was a mistake. Although general causation and causal explanation may well be contrastive in nature, singular causation is not. (shrink)

In this paper I propose a teleological account of epistemic reasons. In recent years, the main challenge for any such account has been to explicate a sense in which epistemic reasons depend on the value of epistemic properties. I argue that while epistemic reasons do not directly depend on the value of epistemic properties, they depend on a different class of reasons which are value based in a direct sense, namely reasons to form beliefs about certain propositions or subject matters. (...) In short, S has an epistemic reason to believe that p if and only if S is such that if S has reason to form a belief about p, then S ought to believe that p. I then propose a teleological explanation of this relationship. It is also shown how the proposal can avoid various subsidiary objections commonly thought to riddle the teleological account. (shrink)

The theory of belief, according to which believing that p essentially involves having as an aim or purpose to believe that p truly, has recently been criticised on the grounds that the putative aim of belief does not interact with the wider aims of believers in the ways we should expect of genuine aims. I argue that this objection to the aim theory fails. When we consider a wider range of deliberative contexts concerning beliefs, it becomes obvious that the aim (...) of belief can interact with and be weighed against the wider aims of agents in the ways required for it to be a genuine aim.

Does transparency in doxastic deliberation entail a constitutive norm of correctness governing belief, as Shah and Velleman argue? No, because this presupposes an implausibly strong relation between normative judgements and motivation from such judgements, ignores our interest in truth, and cannot explain why we pay different attention to how much justification we have for our beliefs in different contexts. An alternative account of transparency is available: transparency can be explained by the aim one necessarily adopts in deliberating about whether to (...) believe that p. To show this, I reconsider the role of the concept of belief in doxastic deliberation, and I defuse 'the teleologian's dilemma'. (shrink)

Epistemic instrumentalists seek to understand the normativity of epistemic norms on the model practical instrumental norms governing the relation between aims and means. Non-instrumentalists often object that this commits instrumentalists to implausible epistemic assessments. I argue that this objection presupposes an implausibly strong interpretation of epistemic norms. Once we realize that epistemic norms should be understood in terms of permissibility rather than obligation, and that evidence only occasionally provide normative reasons for belief, an instrumentalist account becomes available that delivers the (...) correct epistemic verdicts. On this account, epistemic permissibility can be understood on the model of the wide-scope instrumental norm for instrumental rationality, while normative evidential reasons for belief can be understood in terms of instrumental transmission. (shrink)

A popular account of epistemic justification holds that justification, in essence, aims at truth. An influential objection against this account points out that it is committed to holding that only true beliefs could be justified, which most epistemologists regard as sufficient reason to reject the account. In this paper I defend the view that epistemic justification aims at truth, not by denying that it is committed to epistemic justification being factive, but by showing that, when we focus on the relevant (...) sense of ‘justification’, it isn’t in fact possible for a belief to be at once justified and false. To this end, I consider and reject three popular intuitions speaking in favor of the possibility of justified false beliefs, and show that a factive account of epistemic justification is less detrimental to our normal belief forming practices than often supposed.

A popular account of luck, with a firm basis in common sense, holds that a necessary condition for an event to be lucky, is that it was suitably improbable. It has recently been proposed that this improbability condition is best understood in epistemic terms. Two different versions of this proposal have been advanced. According to my own proposal :361–377, 2010), whether an event is lucky for some agent depends on whether the agent was in a position to know that the (...) event would occur. And according to Stoutenburg :319–334, 2015, Synthese, 1–15, 2018), whether an event is lucky for an agent depends on whether the event was guaranteed or certain to occur in light of the agent’s evidence. In this paper, I argue that we should prefer the account in terms of knowledge over that in terms of evidential certainty. (shrink)

The alien invasive Red King Crab in the Barents Sea represents both a threat, via ecosystem impacts, and a gain as a revenue source from food sales. Uncertainties exist regarding the ecological impacts but debate in Norway has also emphasised the economic benefits to marginalised fisher communities. This paper reports on a Q-methodology study involving key stakeholders to probe the extent to which divisions exist between different groups. While divisions are indeed found and two groupings identified, these are not as (...) clear as suggested by the lines typically portrayed in the media and elsewhere -, i.e. economic gains versus ecological preservation. Stakeholder groups reported here generally agreed that biodiversity concerns should be central and that further invasion was undesirable due to potential impacts on ecosystem services. (shrink)

The idea that humans should abandon their individuality and use technology to bind themselves together into hivemind societies seems both farfetched and frightening – something that is redolent of the worst dystopias from science fiction. In this article, we argue that these common reactions to the ideal of a hivemind society are mistaken. The idea that humans could form hiveminds is sufficiently plausible for its axiological consequences to be taken seriously. Furthermore, far from being a dystopian nightmare, the hivemind society (...) could be desirable and could enable a form of sentient flourishing. Consequently, we should not be so quick to deny it. We provide two arguments in support of this claim – the axiological openness argument and the desirability argument – and then defend it against three major objections. (shrink)

When one has both epistemic and practical reasons for or against some belief, how do these reasons combine into an all-things-considered reason for or against that belief? The question might seem to presuppose the existence of practical reasons for belief. But we can rid the question of this presupposition. Once we do, a highly general ‘Combinatorial Problem’ emerges. The problem has been thought to be intractable due to certain differences in the combinatorial properties of epistemic and practical reasons. Here we (...) bring good news: if we accept an independently motivated version of epistemic instrumentalism—the view that epistemic reasons are a species of instrumental reasons—we can reduce The Combinatorial Problem to the relatively benign problem of how to weigh different instrumental reasons against each other. As an added benefit, the instrumentalist account can explain the apparent intractability of The Combinatorial Problem in terms of a common tendency to think and talk about epistemic reasons in an elliptical manner.

Nishi Shah has recently argued that transparency in doxastic deliberation supports a strict version of evidentialism about epistemic reasons. I argue that Shah's argument relies on a principle that is incompatible with the strict version of evidentialism Shah wishes to advocate.

Many have found it plausible that practical circumstances can affect whether someone is in a position to know or rationally believe a proposition. For example, whether it is rational for a person to believe that the bank will be open tomorrow, can depend not only on the person’s evidence, but also on how practically important it is for the person not to be wrong about the bank being open tomorrow. This supposed phenomenon is known as “pragmatic encroachment” on knowledge and (...) rational belief. Assuming that the phenomenon is real, I ask what explains it. I argue that a variant of instrumentalism about epistemic reasons offers a natural explanation, that at the same time is able avoid commitment to a more radical form of pragmatism. (shrink)

The predominant view in developmental psychology is that young children are able to reason with the concept of desire prior to being able to reason with the concept of belief. We propose an explanation of this phenomenon that focuses on the cognitive tasks that competence with the belief and desire concepts enable young children to perform. We show that cognitive tasks that are typically considered fundamental to our competence with the belief and desire concepts can be performed with the concept (...) of desire in the absence of competence with the concept of belief, whereas the reverse is considerably less feasible.

It is widely agreed that obsessive-compulsive disorder involves irrationality. But where in the complex of states and processes that constitutes OCD should this irrationality be located? A pervasive assumption in both the psychiatric and philosophical literature is that the seat of irrationality is located in the obsessive thoughts characteristic of OCD. Building on a puzzle about insight into OCD (Taylor 2022), we challenge this pervasive assumption, and argue instead that the irrationality of OCD is located in the emotions that are (...) characteristic of OCD, such as anxiety or fear. In particular, we propose to understand the irrationality of OCD as a matter of harboring recalcitrant emotions. We argue that this account not only solves the puzzle about insight, but also makes better sense of how OCD sufferers experience and describe their condition and helps explain some otherwise puzzling features of compulsive behavior.

It seems obvious that when higher-order evidence makes it rational for one to doubt that one’s own belief on some matter is rational, this can undermine the rationality of that belief. This is known as higher-order defeat. However, despite its intuitive plausibility, it has proved puzzling how higher-order defeat works, exactly. To highlight two prominent sources of puzzlement, higher-order defeat seems to defy being understood in terms of conditionalization; and higher-order defeat can sometimes place agents in what seem like epistemic (...) dilemmas. This chapter draws attention to an overlooked aspect of higher-order defeat, namely that it can undermine the resilience of one’s beliefs. The notion of resilience was originally devised to understand how one should reflect the ‘weight’ of one’s evidence. But it can also be applied to understand how one should reflect one’s higher-order evidence. The idea is particularly useful for understanding cases where one’s higher-order evidence indicates that one has failed in correctly assessing the evidence, without indicating whether one has over- or underestimated the degree of evidential support for a proposition. But it is exactly in such cases that the puzzles of higher-order defeat seem most compelling. (shrink)

In his influential discussion of the aim of belief, David Owens argues that any talk of such an ‘aim’ is at best metaphorical. In order for the ‘aim’ of belief to be a genuine aim, it must be weighable with other aims in deliberation, but Owens claims that this is impossible. In previous work, I have pointed out that if we look at a broader range of deliberative contexts involving belief, it becomes clear that the putative aim of belief is (...) capable of being weighed against other aims. Recently, however, Ema Sullivan-Bissett and Paul Noordhof have objected to this response on the grounds that it employs an undefended conception of the aim of belief not shared by Owens, and that it equivocates between importantly different contexts of doxastic deliberation. In this note, I argue that both of these objections fail. (shrink)

Epistemic instrumentalists think that epistemic normativity is just a special kind of instrumental normativity. According to them, you have epistemic reason to believe a proposition insofar as doing so is conducive to certain epistemic goals or aims—say, to believe what is true and avoid believing what is false. Perhaps the most prominent challenge for instrumentalists in recent years has been to explain, or explain away, why one’s epistemic reasons often do not seem to depend on one’s aims. This challenge can (...) arguably be met. But a different challenge looms: instrumental reasons in the practical domain have various properties that epistemic reasons do not seem to share. In this chapter, we offer a way for epistemic instrumentalists to overcome this challenge. Our main thesis takes the form of a conditional: if we accept an independently plausible transmission principle of instrumental normativity, we can maintain that epistemic reasons in fact do share the relevant properties of practical instrumental reasons. In addition, we can explain why epistemic reasons seem to lack these properties in the first place: some properties of epistemic reasons are elusive, or easy to overlook, because we tend to think and talk about epistemic reasons in an ‘elliptical’ manner.

According to the thesis of pragmatic encroachment, practical circumstances can affect whether someone is in a position to know or rationally believe a proposition. For example, whether it is epistemically rational for a person to believe that the bank will be open on Saturdays, can depend not only on the strength of the person’s evidence, but also on how practically important it is for the person not to be wrong about the bank being open on Saturdays. In recent years, philosophers (...) have argued that moral considerations can also affect the epistemic rationality of belief, thus giving rise to moral encroachment. In previous work (Steglich-Petersen, forthcoming a), I have developed an explanation of pragmatic encroachment grounded in an instrumentalist theory of epistemic reasons. Here, I argue that this explanation extends to moral encroachment as well, including so-called “radical” moral encroachment. I also show how this explanation dispels the worry raised by Gerken (2019), that pragmatic encroachment might give rise to morally adverse consequences in the form of epistemic injustice. (shrink)

In a recent article, I criticized Kathrin Glüer and Åsa Wikforss's so-called “no guidance argument” against the truth norm for belief, for conflating the conditions under which that norm recommends belief with the psychological state one must be in to apply the norm. In response, Glüer and Wikforss have offered a new formulation of the no guidance argument, which makes it apparent that no such conflation is made. However, their new formulation of the argument presupposes a much too narrow understanding (...) of what it takes for a norm to influence behaviour, and betrays a fundamental misunderstanding of the point of the truth norm. Once this is taken into account, it becomes clear that the no guidance argument fails. (shrink)

Many philosophers have argued that an event is lucky for an agent only if it was suitably improbable, but there is considerable disagreement about how to understand this improbability condition. This paper argues for a hitherto overlooked construal of the improbability condition in terms of the lucky agent’s epistemic situation. According to the proposed account, an event is lucky for an agent only if the agent was not in a position to know that the event would occur. It is also (...) explored whether this new account threatens the anti- luck program in epistemology. It is argued that although not detrimental to the anti- luck program, the epistemic account of luck sets certain important limits to its scope and feasibility. (shrink)

Kathrin Glüer and Åsa Wikforss argue that any truth norm for belief, linking the correctness of believing p with the truth of p, is bound to be uninformative, since applying the norm to determine the correctness of a belief as to whether p, would itself require forming such a belief. I argue that this conflates the condition under which the norm deems beliefs correct, with the psychological state an agent must be in to apply the norm. I also show that (...) since the truth norm conflicts with other possible norms that clearly are informative, the truth norm must itself be informative. (shrink)

Many epistemologists have been attracted to the view that knowledge-wh can be reduced to knowledge-that. An important challenge to this, presented by Jonathan Schaffer, is the problem of “convergent knowledge”: reductive accounts imply that any two knowledge-wh ascriptions with identical true answers to the questions embedded in their wh-clauses are materially equivalent, but according to Schaffer, there are counterexamples to this equivalence. Parallel to this, Schaffer has presented a very similar argument against binary accounts of knowledge, and thereby in favour (...) of his alternative contrastive account, relying on similar examples of apparently inequivalent knowledge ascriptions, which binary accounts treat as equivalent. In this article, I develop a unified diagnosis and solution to these problems for the reductive and binary accounts, based on a general theory of knowledge ascriptions that embed presuppositional expressions. All of Schaffer's apparent counterexamples embed presuppositional expressions, and once the effect of these is taken into account, it becomes apparent that the counterexamples depend on an illicit equivocation of contexts. Since epistemologists often rely on knowledge ascriptions that embed presuppositional expressions, the general theory of them presented here will have ramifications beyond defusing Schaffer's argument.

Research indicates the essentiality of dignity as a vital component for quality of life, reconfirming the emphasis on dignity preservation in the international code of nursing ethics. Applying Noblit and Hare’s meta-ethnography, the aim of the study was to develop a theory model by synthesizing 10 qualitative articles from various cultural contexts, exploring nurse and allied healthcare professional perception/practice concerning dignity-preserving dementia care. “Advocating the person’s autonomy and integrity,” which involves “having compassion for the person,” “confirming the person’s worthiness and (...) sense of self,” and “creating a humane and purposeful environment,” was identified as a primary foundation for dignity-preserving dementia care. “Balancing individual choices among persons no longer able to make sound decisions, against the duty of making choices on behalf of the person,” which involves “persuasion” and/or “mild restraint,” was considered a crucial aspect in certain situations. “Sheltering human worth—remembering those who forget” was identified as a comprehensive motive and core value within dignity-preserving dementia care.

A number of authors have recently developed and defended various versions of ‘normative essentialism’ about the mental, i.e. the claim that propositional attitudes are constitutively or essentially governed by normative principles. I present two arguments to the effect that this claim cannot be right. First, if propositional attitudes were essentially normative, propositional attitude ascriptions would require non-normative justification, but since this is not a requirement of folk-psychology, propositional attitudes cannot be essentially normative. Second, if propositional attitudes were essentially normative, propositional (...) attitude ascriptions could not support normative rationality judgments, which would remove the central appeal of normative essentialism.

Most of us want to have children. We want them to be healthy and have a good start in life. One way to achieve this goal is to use preimplantation genetic diagnosis . PGD enables people engaged in the process of in vitro fertilisation to acquire information about the genetic constitution of an early embryo. On the basis of this information, a decision can be made to transfer embryos without genetic defects to the uterus and terminate those with genetic defects.1However, (...) is it morally acceptable to use PGD to reduce the probability of children with severe genetic diseases being born? Is the current routine use of PGD in public healthcare services to select against severe genetic diseases like anencephaly, spina bifida, cystic fibrosis and Down’s syndrome morally acceptable?These are complex questions involving a range of difficult ethical issues—for instance, critical discussions about the morality of embryo research and embryo termination.2 They also involve awkward conceptual issues concerning such matters as the meaning of words such as “disability”3 and “severe” in “severe genetic diseases”,4 which will not be discussed here.In this paper I examine an argument which aims to show that efforts to prevent the birth of severely disabled children using PGD are morally unacceptable. Essentially, this argument appeals to our concern for disabled people and the belief that PGD, through a slippery slope process, will have bad consequences for them. I conclude that the argument is problematic for a number of reasons. But before I examine the argument itself, it will be helpful to separate two types of slippery slope argument since these involve different kinds of reasoning.TWO TYPES OF ARGUMENTMany of the arguments against PGD point to the bad consequences it can be expected to have for disabled people. Central to all these …. (shrink)

While research on Attention Deficit Hyperactivity Disorder (ADHD) has traditionally focused on cognitive and behavioral deficits, there is increasing interest in exploring possible resources associated with the disorder. In this paper, we argue that the attention-patterns associated with ADHD can be understood as expressing an alternative style of inquiry, or “zetetic” style, characterized mainly by a lower barrier for becoming curious and engaging in inquiry, and a weaker disposition to regulate curiosity in response to the cognitive and practical costs associated (...) with inquiry. Exploring this zetetic style from an epistemological perspective, we show that it is often epistemically rational and can be advantageous in important respects. We close by suggesting that the very aspects of the zetetic style that might at times render it disadvantageous from the point of view of individual subjects with ADHD, will often confer epistemic benefits to the social group that the subjects are part of.

Psychological studies on fictional persuasion demonstrate that being engaged with fiction systematically affects our beliefs about the real world, in ways that seem insensitive to the truth. This threatens to undermine the widely accepted view that beliefs are essentially regulated in ways that tend to ensure their truth, and may tempt various non-doxastic interpretations of the belief-seeming attitudes we form as a result of engaging with fiction. I evaluate this threat, and argue that it is benign. Even if the relevant (...) attitudes are best seen as genuine beliefs, as I think they often are, their lack of appropriate sensitivity to the truth does not undermine the essential tie between belief and truth. To this end, I shall consider what I take to be the three most plausible models of the cognitive mechanisms underlying fictional persuasion, and argue that on none of these models does fictional persuasion undermine the essential truth-tie.

Many philosophers have sought to account for doxastic and epistemic norms by supposing that belief ‘aims at truth.’ A central challenge for this approach is to articulate a version of the truth-aim that is at once weak enough to be compatible with the many truth-independent influences on belief formation, and strong enough to explain the relevant norms in the desired way. One phenomenon in particular has seemed to require a relatively strong construal of the truth-aim thesis, namely ‘transparency’ in doxastic (...) deliberation. In this paper, I argue that the debate over transparency has been in the grip of a false presupposition, namely that the phenomenon must be explained in terms of being a feature of deliberation framed by the concept of belief. Giving up this presupposition makes it possible to adopt weaker and more plausible versions of the truth-aim thesis in accounting for doxastic and epistemic norms. (shrink)

In a recent paper (2008), I presented two arguments against the thesis that intentional states are essentially normative.

I present and develop a novel account of the schematism by reading it through the distinction between constitution and regulation. I thus show that Kant’s stipulation of only eight schemata for the twelve pure concepts of the understanding is not haphazard but answers, instead, to two distinct processes of synthesis, mathematical and dynamical, that either constitute objects in intuition or regulate objects of experience. Based on this, I offer a detailed reconstruction of each of the schemata specified by Kant, and (...) I provide an explanation of the systematic role each plays in the Analytic. (shrink)

It is widely assumed that doxastic deliberation is transparent to the factual question of the truth of the proposition being considered for belief, and that this sets doxastic deliberation apart from practical deliberation. This feature is frequently invoked in arguments against doxastic voluntarism. I argue that transparency to factual questions occurs in practical deliberation in ways parallel to transparency in doxastic deliberation. I argue that this should make us reconsider the appeal to transparency in arguments against doxastic voluntarism, and the (...) wider issue of distinguishing theoretical from practical rationality.

Both traditional and recent accounts of the beneficial and therapeutic effects of psychedelic experiences tie these effects to specifically epistemic changes, for example the enabling of spiritual or psychological insight, or disruption of problematic beliefs or thought patterns. While these alleged benefits have sometimes been thought to be facilitated by false or even delusional beliefs (e.g. Pollan 2015), recent philosophical discussion strikes a more optimistic tone, arguing that the epistemic risks involved with psychedelic drug use tend to be relatively benign (...) and outweighed by epistemic benefits (Letheby 2021). In this paper, we seek to nuance this picture by drawing attention to the crucial role played by social factors in determining the epistemic effects of psychedelic experiences. We argue that the very openness of mind and heightened sense of clarity and certainty that is often thought to facilitate the epistemic benefits of psychedelic drug use, also make the user more vulnerable to adverse epistemic influence from the social environment, to a degree not acknowledged in the current literature. Examining the epistemic influences of the social environment is thus important for understanding the necessary precautions of informed consent and overall safe drug use. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Mild Cognitive Impairment Is RelevantRonald C. Petersen (bio)Keywordsaging, Alzheimer’s disease, dementia, mild cognitive impairment, pharmaceutical industryGraham and Ritchie (2006) have contributed a scholarly document that implores us to reexamine nosological categories and certain diagnostic outcomes. They have chosen mild cognitive impairment (MCI) as the target of their scrutiny and have raised several interesting issues. I would like to comment on their approach and suggest that MCI is a (...) useful clinical entity that does serve a practical function and hopefully will lead to a better quality of life for aging persons.There are several clarifications concerning the construct of MCI that need to be emphasized. Graham and Ritchie have asserted that all persons with MCI eventually evolve to Alzheimer's disease (AD) and have claimed that this is the inevitable outcome of the disorder. Although it is true that many of the early studies on MCI focused on the amnestic subtype as a precursor to AD (Bennett et al. 2002; Ganguli, Dodge, Shen, and DeKosky 2004; Lopez et al. 2003; Petersen et al. 1999), subsequent work has expanded the construct to include prodromal forms of other disorders (Petersen 2004; Winblad et al. 2004). As such, the construct of MCI has become flexible in recent years to account for alternative types of intermediate cognitive impairment.The authors state that MCI addresses those individuals speculated to have an inevitable dementia. Certainly, we do not presume that dementia is inevitable in the aging process; rather, we posit that if certain criteria are fulfilled in persons who are aging, the likelihood of a person progressing to a certain type of dementia is quite high. As such, this is an important precondition about which to learn, because interventional strategies may be available.Graham and Ritchie argue that some cognitive changes with aging are "normal" and trying to classify these individuals as "abnormal" is performing a disservice to much of the aging population. We draw an important distinction between the cognitive changes of normal aging, as they are recognized to exist, and what we feel constitutes the pathologic changes of MCI. We believe that the abnormal cognitive function found in MCI has a high probability of progressing to a greater degree of cognitive dysfunction in a relatively short period of time and these behavioral changes are accompanied by pathologic brain changes that are manifested on magnetic resonance imaging scans, positron emission tomography scans, cerebrospinal fluid biomarkers, and autopsy studies (Hampel et al. 2004; Jack et al. 1999; Markesbery et al. [End Page 45] 2006; Petersen et al. 2006). This type of progression is in contradistinction to other individuals who are experiencing cognitive changes of normal aging. These individuals do not progress rapidly to greater degrees of impairment and autopsy studies reveal that their brains do not harbor the pathologic changes found in the MCI population (Knopman et al. 2003).The cognitive and behavioral changes accompanying persons with MCI are devastating and cannot be ascribed to "senility" or "He is just getting old." It is a mistake to imply that by labeling people with a condition such as MCI we are doing them a disservice. Most of these individuals are seeking medical attention for their perceived difficulties. Consequently, addressing these concerns and educating the individuals on the implications of their symptoms are important services. Although we may not have adequate therapies at present, this does not imply that we should ignore the symptoms.We cannot treat many conditions at present, yet we do not avoid the opportunity to characterize the condition and make a diagnosis. Even if this were part of the aging process, this does not mean that we should ignore the disability and refuse to treat it. Most individuals develop an inflexibility of their optical lenses as they age, yet corrective lenses of one type or another are believed to be extremely beneficial at alleviating this disability associated with the aging phenomenon. No one would argue that it is inappropriate to treat this condition because it is "just a part of aging."It should be noted that I have stressed the situation in which individuals are seeking medical attention for their cognitive concerns. It is quite a different situation if an... (shrink)

In this article several justifications of what I call ‘the claim from adoption’ are examined. The claim from adoption is that, instead of expending resources on bringing new children into the world using reproductive technology and then caring for these children, we ought to devote these resources to the adoption and care of existing destitute children. Arguments trading on the idea that resources should be directed to adoption instead of assisted reproduction because already existing people can benefit from such a (...) use of resources whereas we cannot benefit individuals by bringing them into existence are rejected. It is then argued that a utilitarian argument proposed by Christian Munthe that supports the claim from adoption in some situations should be rejected because the support it offers does not extend to certain situations in which it seems morally obvious that resources should be expended on adoption rather than assisted reproduction. A version of the Priority View improves upon Munthe’s utilitarianism by supporting the claim from adoption in the cases in which Munthe’s argument failed. Some allegedly counterintuitive implications of the Priority View are then discussed, and it is concluded that the Priority View is more plausible than utilitarianism. n a concluding section on policy issues it is argued that, even though the claim from adoption can be justified in a variety of situations, it does not follow that, in these situations, governments should direct resources away from assisted reproduction and towards adoption.

Causation is of undeniable importance to our understanding of, and interaction with our surroundings. Despite this, the correct understanding of causation remains subject to considerable philosophical controversy. In this article, I introduce the most influential philosophical theories of causation, and provide an overview of the main difficulties that has led to the currently most popular versions of these theories.

In this article several justifications of what I call ‘the claim from adoption’ are examined. The claim from adoption is that, instead of expending resources on bringing new children into the world using reproductive technology and then caring for these children, we ought to devote these resources to the adoption and care of existing destitute children.Arguments trading on the idea that resources should be directed to adoption instead of assisted reproduction because already existing people can benefit from such a use (...) of resources whereas we cannot benefit individuals by bringing them into existence are rejected. It is then argued that a utilitarian argument proposed by Christian Munthe that supports the claim from adoption in some situations should be rejected because the support it offers does not extend to certain situations in which it seems morally obvious that resources should be expended on adoption rather than assisted reproduction. A version of the Priority View improves upon Munthe’s utilitarianism by supporting the claim from adoption in the cases in which Munthe’s argument failed. Some allegedly counterintuitive implications of the Priority View are then discussed, and it is concluded that the Priority View is more plausible than utilitarianism.n a concluding section on policy issues it is argued that, even though the claim from adoption can be justified in a variety of situations, it does not follow that, in these situations, governments should direct resources away from assisted reproduction and towards adoption.
