Some obligations are conditional such that act A is morally optional, but if one chooses A, one is required to do act B rather than some other less valuable act C. Such conditional obligations arise frequently in research ethics, in the philosophical literature, and in real life. They are controversial: how does a morally optional act give rise to demanding requirements to do the best? Some think that the fact that a putative obligation has a conditional structure, so defined, is (...) a strike against its being a genuine obligation. I argue that conditional obligations are to be expected in a moral theory that has moral options. (shrink)

Millions of children worldwide could benefit from adoption. One could argue that prospective parents have a pro tanto duty to adopt rather than create children. For the sake of argument, I assume there is such a duty and focus on a pressing objection to it. Prospective parents may prefer that their children are genetically related to them. I examine eight reasons prospective parents have for preferring genetic children: for parent-child physical resemblance, for family resemblance, for psychological similarity, for the sake (...) of love, to achieve a kind of immortality, for the genetic connection itself, to be a procreator, and to experience pregnancy. I argue that, with the possible exception of the pregnancy desire, these reasons fail to defeat a duty to adopt a child rather than create one, even assuming that we do have some leeway to favor our own interests.

This article argues that two forms of mitochondrial replacement therapy, maternal spindle transfer and pro-nuclear transfer, are not therapies at all because they do not treat children who are coming into existence. Rather, these technologies merely create healthy children where none was inevitable. Even if creating healthy lives has some value, it is not to be confused with the medical value of a cure or therapy. The article addresses a recent Bioethics article, ‘Mitochondrial Replacement: Ethics and Identity,’ by Wrigley, Wilkinson, (...) and Appleby, who argue that PNT is morally favorable to MST due to the Non-Identity Problem. Wrigley et al. claim that PNT, since it occurs post-conception, preserves the identity of the resulting child, whereas MST, since it occurs pre-conception, is an identity-altering technique. As such, a child born with mitochondrial disease could complain that her parents failed to use PNT, but not MST. The present article argues that the authors are mistaken: both MST and PNT are identity-affecting techniques. But this is of little matter, for we should be cautious in drawing any moral conclusions from the application of the Non-Identity Problem to cases. The article then argues that the authors are mistaken in inferring that PNT is a type of embryonic cure or therapy for children with mitochondrial disease. The article cautions against the mistaken life-saving rhetoric that is common in bioethics discussions of MRTs. (shrink)

In February 2016, the Institute of Medicine released a report, commissioned by the United States Food and Drug Administration, on the ethical and social‐policy implications of so‐called three‐parent in vitro fertilization. The IOM endorses commencement of clinical trials on three‐parent IVF, subject to some initial limitations. Also called mitochondrial replacement or transfer, three‐parent IVF is an intervention comprising two distinct procedures in which the genetic materials of three people—the DNA of the father and mother and the mitochondrial DNA of an (...) egg donor—can be used to create a child. Three‐parent IVF would enable a woman with mitochondrial disease to have a genetically related child without transmitting the disease to the child. The possibility for three‐parent children has prompted criticism from many corners. Critics have pointed to ethical issues including safety concerns and risks to children, genetic and germline engineering concerns, the potential exploitation of the third‐parent egg donor, donor anonymity and privacy, and objections to creating babies with three parents, which undermines natural and traditional conceptions of procreation. Additionally, developing the technology would involve experimenting on, manipulating, and disposing of embryos. Although the IOM report considers the ethical concerns about the value of the three‐parent IVF technology, the IOM failed to give due attention to an important objection to the development of this technology: three‐parent IVF lacks the social value necessary to make investment of public resources in it ethical.Unlike the other concerns, this objection is not based on conservativism about new reproductive technologies or default favoritism of the status quo. I argue that the technology does not meet a plausible social value standard to render public research investment into its development ethical. Proponents of three‐parent IVF make inaccurate and exaggerated claims that it will eradicate mitochondrial disease and save lives. Were these claims true, proponents would have a strong case for the social value of the technology. But three‐parent IVF alone will not eradicate mitochondrial disease, and it will not save lives. Rather, it can create healthy lives. As I discuss, the moral distinction is crucial. Most importantly, investment in three‐parent IVF comes at the opportunity cost of researching treatment for mitochondrial disease that would benefit actual, living disease sufferers. (shrink)

The independence of irrelevant alternatives is a popular and important axiom of decision theory. It states, roughly, that one’s choice from a set of options should not be influenced by the addition or removal of further, unchosen options. In recent debates, a number of authors have given putative counterexamples to it, involving intuitively rational agents who violate IIA. Generally speaking, however, these counterexamples do not tend to move IIA’s proponents. Their strategy tends to be to individuate the options that the (...) agent faces differently, so that the case no longer counts as a violation of IIA. In this paper, we examine whether this strategy succeeds. We argue that the ways of individuating options required to save IIA from the most problematic counterexamples—in particular, cases where agents violate IIA due to nonconsequentialist moral beliefs—do so only at the expense of severely compromising its central function within decision theory.

In this paper I examine the debate between ‘protectionists’ and ‘liberationists’ concerning the appropriate role of minors in decision-making about their health care, focusing particularly on disagreements between the two sides regarding adolescents. Protectionists advocate a more traditional, paternalistic approach in which minors have relatively little input into the healthcare decision-making process, and decisions are made for them by parents or other adults, guided by a commitment to the patient's best interests. Liberationists, on the other hand, argue in favour of (...) expanded participation by minors in treatment decisions, and decision-making authority for at least some adolescents. My examination of the debate includes discussion of liberationist shifts that have taken place in the medical community as well as in legal policy and practice, and consideration of recent research on adolescent development. In the final section of the paper, I propose a moderate position that addresses both liberationist and protectionist concerns. (shrink)

Aesthetics and Music is a rich and interesting study. Hamilton's approach is innovative. He interleaves chapters on the history of philosophical thought about music with more theoretical discussions of music, sound, rhythm and improvisation, but does not cover the work–performance relation, depiction or expression. He draws on an atypically broad range of examples, including avant-garde, medieval, non-Western and jazz. The assumptions are humanist: ‘I wish to argue for an aesthetic conception of music as an art … according to which music (...) is a human activity grounded in the body and bodily movement and interfused with human life’.The historical chapters are valuable and not without analysis and criticism. Hamilton shows how the ancient Greek theorists were more interested in music's mathematical properties as reflecting the underlying harmony of relations between cosmic bodies than in the practice of musicians. While they equated the value of art with its contribution to an education for citizenship and while their concept of the arts differed …. (shrink)

CRISPR Cas9-powered gene drive allows for the rapid alteration of malaria-causing mosquitoes to spread an infertility gene or resistance to malaria among their species. Malaria eradication would be a great boon to human health. But many are concerned with driving genetic changes through a natural species. This chapter catalogs objections to the use of gene drive in mosquitoes for eradicating malaria. In-principle objections to gene drive use are not compelling. The most urgent concerns are related to the safety of the (...) technology for the environment and human health. Philosophers play a critical role in working along scientists to develop risk/benefit models that weigh the reasons for and against gene drive to eradicate malaria based on our best scientific knowledge and rigorous normative reasoning.

There is a lot that we don't know. That means that there are a lot of possibilities that are, epistemically speaking, open. For instance, we don't know whether it rained in Seattle yesterday. So, for us at least, there is an epistemic possibility where it rained in Seattle yesterday, and one where it did not. What are these epistemic possibilities? They do not match up with metaphysical possibilities - there are various cases where something is epistemically possible but not metaphysically (...) possible, and vice versa. How do we understand the semantics of statements of epistemic modality? The ten new essays in this volume explore various answers to these questions, including those offered by contextualism, relativism, and expressivism. (shrink)

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing to (...) adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

How should we characterize the functional role of conscious visual experience? In particular, how do the conscious contents of visual experience guide, bear upon, or otherwise inform our ongoing motor activities? According to an intuitive and philosophically influential conception, the links are often quite direct. The contents of conscious visual experience, according to this conception, are typically active in the control and guidance of our fine-tuned, real-time engagements with the surrounding three-dimensional world. But this idea is hostage to empirical fortune. (...) It is a hostage, moreover, whose safety is in serious doubt. Thus Milner and Goodale argue for a deep and abiding dissociation between the contents of conscious seeing, on the one hand, and the resources used for the on-line guidance of visuo-motor action, on the other. This ‘dual visual systems’ hypothesis, which finds many echoes in various other bodies of cognitive scientific research, poses a prima facie challenge to the Assumption of Experience-Based Control. More importantly, it provides fuel for an alternative and philosophically suggestive account of the functional role of conscious visual experience. (shrink)

We show that a popular class of connectionist models (which we label 'first order connectionism') looks unlikely to provide the kind of resources required by the hypothesis.

This article discusses how research on the image-based analysis of facial images has informed this debate by demonstrating that a single representational system for facial identity and facial expression is not only computationally viable, but can simulate existing cognitive data demonstrating apparent dissociable processing of these two facial properties. It discusses the increasing number of cognitive studies that provide support for this view. Neuropsychological case studies of brain-injured patients and provide limited evidence for separate visual routes processing facial identity and (...) facial expression. It deals with neuroimaging studies addressing both facial identity and facial expression processing which shows that the fusiform gyrus contributes to the recognition of both facial properties. Research continues to reinforce the proposal that a common visual framework supports the representation of at least some aspects of facial identity and facial expression. (shrink)

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind.

We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

I argue against Schroeder's explanation of pragmatic encroachment on knowledge. In section 1, I introduce pragmatic encroachment and point out that an explanation of it should avoid Pascalian considerations. In section 2, summarize the key aspects of Schroeder's explanation of pragmatic encroachment. In section 3, I argue that Schroeder's explanation faces a dilemma: it either allows for an objectionable form of Pascalian encroachment or it fails to be a fully general explanation of pragmatic encroachment.

Subjects with delusions profess to believe some extremely peculiar things. Patients with Capgras delusion sincerely assert that, for example, their spouses have been replaced by impostors. Patients with Cotard’s delusion sincerely assert that they are dead. Many philosophers and psychologists are hesitant to say that delusional subjects genuinely believe the contents of their delusions.2 One way to reinterpret delusional subjects is to say that we’ve misidentified the content of the problematic belief. So for example, rather than believing that his wife (...) is has been replaced by an impostor, we might say that the victim of Capgras delusion believes that it is, in some respects, as if his wife has been replaced by an impostor. Another is to say that we’ve misidentified the attitude that the delusional subject bears to the content of their delusion. So for example, Gregory Currie and co-authors have suggested that rather than believing that his wife has been replaced by an impostor, we should say that the victim of Capgras delusion merely imagines that his wife has been replaced by an impostor.3.

Mind, it is increasingly fashionable to assert, is an intrinsically embodied and environmentally embedded phenomenon. But there is a potential tension between two strands of thought prominent in this recent literature. One of those strands depicts the body as special, and the fine details of a creature’s embodiment as a major constraint on the nature of its mind: a kind of new-wave body-centrism. The other depicts the body as just one element in a kind of equal-partners dance between brain, body (...) and world, with the nature of the mind fixed by the overall balance thus achieved: a kind of extended functionalism (now with an even broader canvas for multiple realizability than ever before). The present paper displays the tension, scouts the space of possible responses, and ends by attempting to specify what the body actually needs to be, given its complex role in these recent debates.

Finally, Sect. 6 concerns the normativity of my proposed knowledge norm and its significance.

Clinicians and health researchers frequently encounter opportunities to rescue people. Rescue cases can generate a moral duty to aid those in peril. As such, bioethicists have leveraged a duty to rescue for a variety of purposes. Yet, despite its broad application, the duty to rescue is under-analyzed. In this paper, we assess the state of theorizing about the duty to rescue. There are large gaps in bioethicists’ understanding of the force, scope, and justification of the two most cited duties to (...) rescue—the individual duty of easy rescue and the institutional rule of rescue. We argue that the duty of easy rescue faces unresolved challenges regarding its force and scope, and the rule of rescue is indefensible. If the duty to rescue is to help solve ethical problems, these theoretical gaps must be addressed. We identify two further conceptions of the duty to rescue that have received less attention—an institutional duty of easy rescue and the professional duty to rescue. Both provide guidance in addressing force and scope concerns and, thereby, traction in answering the outstanding problems with the duty to rescue. We conclude by proposing and propose research priorities for developing accounts of duties to rescue in bioethics. (shrink)

In the first part, he presents an overview of the contemporary debates about epistemic norms for practical reasoning, and defends the thesis that epistemic rationality can make one practically irrational.

In the second part Mueller considers current approaches to pragmatic encroachment in epistemology, ultimately (...) arguing in favor of a new principle-based argument for pragmatic encroachment. While the book defends tenets of the knowledge-first programme, one of its main conclusions is thoroughly pragmatist: in an important sense, the practical has primacy over the epistemic. (shrink)

Health care institutions must decide whether to inform the patient of a medical error. The barriers to disclosure are an aversion to admitting errors, a concern about implicating other practitioners, and a fear of lawsuits and liability. However, admission of medical errors is the ethical thing to do and may be required by law. When examined, the barriers to such disclosures have little merit, and, in fact, lawsuits and liability may actually be reduced by informing the patient of medical errors. (...) Therefore, a health care institution should implement a written policy providing for disclosure of medical errors, using a process such as that outlined in the article. (shrink)

Idioms – expressions like kick the bucket and let the cat out of the bag – are strange. They behave in ways that ordinary multi-word expressions do not. One distinctive and troublesome feature of idioms is their unpredictability: The meanings of sentences in which idiomatic phrases occur are not the ones that we would get by applying the usual compositional rules to the usual meanings of their (apparent) constituents. This sort of behavior requires an explanation. I will argue that the (...) right explanation is that the sentences are being interpreted through a pretense. (What this means, exactly, will be explained in what follows.) This is a surprising claim, for two reasons. On the one hand, it seems that adopting a pretense account is overkill—it’s a far more radical move than is required to account for the phenomena. On the other hand, it seems that a pretense account is hopeless—that there is a fatal overgeneration problem for pretense accounts of idiom that causes them to fail, as Jason Stanley charges, “as badly as it is possible for an account of idiom to fail.” So I will have some work to do.

Given recent advancements in CRISPR‐Cas9 powered genetic modification of gametes and embryos, both popular media and scientific articles are hailing CRISPR’s life‐saving, curative potential for people with serious monogenic diseases. But claims that CRISPR modification of gametes or embryos, a form of germline engineering, has therapeutic value are deeply mistaken. This article explains why reproductive uses of CRISPR, and germline engineering more generally, do not treat or save lives that would otherwise have a genetic disease. Reproductive uses of CRISPR create (...) healthy people whose existence is not inevitable in the first place. Creating healthy lives has distinct and lesser moral value from saving or curing lives that would otherwise have genetic disease. The real value in reproductive uses of CRISPR is in helping a very limited population of people have healthy, genetically related children. This diminished value cannot compete with the concerns in opposition to germline engineering, nor is it worth the investment of research money. (shrink)

Most people would agree that adoption is a good thing for children in need of a family. Yet adoption is often considered a second best or even last resort for parents in making their families. Against this assumption, I explore the unique value of adoption for prospective parents. I begin with a criticism of the selective focus on the value of adoption for only those people using assisted reproductive technologies. I focus on the value of adoption for all prospective parents, (...) reflecting on non-relative, non-procreative adoptions. First, adoption can meet the important need that a child has for a family, whereas procreation creates rather than meets needs. Second, adoption provides a morally noble opportunity to extend to a stranger benefits usually withheld for one's genetic kin. As such, adoption offers a unique possibility in which impartial concern for an other can be the starting point for a lifetime of love and care. Finally, adoptions can have transformative power over adoptive parents’ conception of family and self. In highlighting the unique value of adoption, I aim to challenge the widespread assumption that adoption has second best status to procreation. Indeed adoption can exemplify the human potential for moral compassion and impartial concern for the needs of others. (shrink)

Bobier argued that hope is necessary for practical deliberation. I will demonstrate that Bobier’s argument for this thesis fails.

My understanding is that proximate explanations concern adaptive mechanism and that ultimate explanations concern adaptive rationale. Viewed in this light, the two kinds of explanation are quite distinct, but they interact in a complementary way to give a full understanding of biological adaptations. In contrast, Laland et al. (2013)—following a literal reading of Mayr (Science 134:1501–1506, 1961)—have characterized ultimate explanations as concerning any and all mechanisms that have operated over the course of an organism’s evolutionary history. This has unfortunate consequences, (...) such as allowing random drift to form the basis for ultimate explanations, and allowing proximate and ultimate explanations to bleed into each other until their distinction is meaningless. Here, I suggest Laland et al’s explanatory framework of “reciprocal causation” is not conducive to successful biological science, and that they have misunderstood key elements of the theory of Darwinian adaptation.

Biological brains are increasingly cast as ‘prediction machines’: evolved organs whose core operating principle is to learn about the world by trying to predict their own patterns of sensory stimulation. This, some argue, should lead us to embrace a brain-bound ‘neurocentric’ vision of the mind. The mind, such views suggest, consists entirely in the skull-bound activity of the predictive brain. In this paper I reject the inference from predictive brains to skull-bound minds. Predictive brains, I hope to show, can be (...) apt participants in larger cognitive circuits. The path is thus cleared for a new synthesis in which predictive brains act as entry-points for ‘extended minds’, and embodiment and action contribute constitutively to knowing contact with the world.

How is it that thoroughly physical material beings such as ourselves can think, dream, feel, create and understand ideas, theories and concepts? How does mere matter give rise to all these non-material mental states, including consciousness itself? An answer to this central question of our existence is emerging at the busy intersection of neuroscience, psychology, artificial intelligence, and robotics.In this groundbreaking work, philosopher and cognitive scientist Andy Clark explores exciting new theories from these fields that reveal minds like ours to (...) be prediction machines - devices that have evolved to anticipate the incoming streams of sensory stimulation before they arrive. These predictions then initiate actions that structure our worlds and alter the very things we need to engage and predict.

What emerges is a bold, new, cutting-edge vision that reveals the brain as our driving force in the daily surf through the waves of sensory stimulation. (shrink)

Reid rejects the image theory --the representative or indirect realist position--that memory-judgements are inferred from or otherwise justified by a present image or introspectible state. He also rejects the trace theory , which regards memories as essentially traces in the brain. In contrast he argues for a direct knowledge account in which personal memory yields unmediated knowledge of the past. He asserts the reliability of memory, not in currently fashionable terms as a reliable belief-forming process, but more elusively as a (...) principle of Commonsense. There remains a contemporary consensus against Reid's position. I argue that Reid's critique is essentially sound, and that the consensus is mistaken; personal memory judgements are spontaneous and non-inferential in the same way as perceptual judgements. But I question Reid's account of the connection between personal memory and personal identity. My primary concern is rationally reconstructive rather than scholarly, and downplays recent interpretations of Reid's faculty psychology as a precursor of functionalism and other scientific philosophies of mind.

Introduction Jamie Allen Time, of all the dimensions readily presented to experience, seems to do so most readily through things. Stuff, in supposed counter-valence to the negentropic resilience of living things, appears to us as that which degrades through time, and demarcates a more technical chronometry of sequential events. Situated outside the rotting of fruit and the ticking of clocks, a “deep time” persists. Like the ultra-hearing of the bat, and the infra-vision of the boa-constrictor, there exist living and non-living (...) agents and entities capable of revealing the fixity and finitude of our own perceptual frames for thinking and understanding. The recordings presented here consist of four extracts of documents made in deep geological repository sites (for the storage of nuclear waste). Here re-presented are the Yucca Mountain Repository; HADES, in Mol, Belgium; Gorleben in Germany and a further recording from Forsmark in Sweden (pretty much inaudible behind a loop of a pop song). These recordings are imagined acoustic amplifications of deep time, just as the astronomer’s telescope is (thought of a certain way), also a time machine. Stars and nuclear waste are unapparent objects of temporal thought. Andy Weir is an artist from London researching effects of deprioritised subjectivity and contemporary art. This project draws on work developing sonic fictions, stealthy earworms, and micropolitical agencies. Prompted for further thoughts about the recordings presented here, he offered up the interspersed discussion included. —JA Yucca Mountain Repository, Nevada, USA by continent I became interested in these sites originally as spaces that allude to a time outside of the human (‘deep time’) as they are designed to store waste ‘without future maintenance’. The very fact of thinking about these spaces or working on them—engineering etc.. (as I’m particularly interested them in a kind of practice rather than just an object of thought), in other words, forces a confrontation with thought of the extinction of humanity. I was interested in this as a production of affect at odds with the expected ‘ironic, can be whatever you like’ interpretive condition of contemporary art (art under the condition of neoliberalism, say, where the individual subject is prioritised as a free autonomous producer of the meaning of the work) When I thought about this a bit though it ran into paradoxes—yes, I could allude to deep time, but in doing so I just allude to its un-representability, drawing attention to the limits of representation and so reaffirming it—I was stuck in a representation/non-representational negative dialectic. In trying to somehow create a figure for deep time I was either reducing it to my description of it, or presenting it as irreducible. HADES Facility, Mol, Belgium by continent I don’t think I’ve escaped this in the work but my response to it was to create a sonic-fiction. This was based on the idea of a viral transmission of the affect of deep time (this is the ‘pyroclastic-soaked chrono-dread’) through receiving apparatuses, transforming the screen into an intercessor or mediating lure for the outside, a site of exposure multiplying virulently through its dissemination, invoking as much as trying to represent these spaces, the sounds as durations of exposure to contagious materials, and fictions as a way of excavating the strangeness of a world opaque to subjective reconfiguration... Testing out I suppose ways that art could start thinking about figuring the reality of ecological crisis. Gorleben Repository, Lower Saxony, Germany by continent While everything remains at the level of fiction I think the work is problematic. It doesn’t really model anything, giving too much authority to either romantic abandonment or the recuperation of romantic abandonment under its description by theory/philosophy, all contained and controlled by me within a fairly limited condition of what art can do. Deep Time Contagion is precisely a materialisation of and transmission of this paradox (i.e. with screen-media can only present deep time as unrepresentable or draw attention to an inability to present it) taking the comfort/panic induced by this paradox as its material. I’m working now on some new projects that take this as a point of departure. Forsmark Repository, Sweden (Robitussin Mix) by continent. (shrink)

It is widely assumed that people have a moral right to procreate. This article explores recent arguments in opposition to procreation in some or all contexts. Some such views are concerned with the risks and harms of life that procreation imposes on non-consenting children. Others articulate concerns for third parties – the environmental damage or opportunity costs that procreation poses to already existing people. The article then surveys arguments that favor procreation despite the risks to the children created and third (...) parties. The best argument for procreation is based on the significant interest people have in forming the parent–child relationship. An important under-discussed middle ground is suggested – one that avoids the criticisms of the anti-natalist while fulfilling the best aims of procreation – viz. adoption. The duty to adopt is summarized and objections to it considered. Thoughtful people who deeply desire to become parents but do not wish to participate in the range of potential procreative harms should consider adoption as a first choice. (shrink)

Recent work in cognitive and computational neuroscience depicts human brains as devices that minimize prediction error signals: signals that encode the difference between actual and expected sensory stimulations. This raises a series of puzzles whose common theme concerns a potential misfit between this bedrock informationtheoretic vision and familiar facts about the attractions of the unexpected. We humans often seem to actively seek out surprising events, deliberately harvesting novel and exciting streams of sensory stimulation. Conversely, we often experience some wellexpected sensations (...) as unpleasant and to-be-avoided. In this paper, I explore several core and variant forms of this puzzle, using them to display multiple interacting elements that together deliver a satisfying solution. That solution requires us to go beyond the discussion of simple information-theoretic imperatives and to recognize the essential role of species-specific prestructuring, epistemic foraging, and cultural practices in shaping the restless, curious, novelty-seeking human mind.

Some regularities enjoy only an attenuated existence in a body of training data. These are regularities whose statistical visibility depends on some systematic recoding of the data. The space of possible recodings is, however, infinitely large – it is the space of applicable Turing machines. As a result, mappings that pivot on such attenuated regularities cannot, in general, be found by brute-force search. The class of problems that present such mappings we call the class of “type-2 problems.” Type-1 problems, by (...) contrast, present tractable problems of search insofar as the relevant regularities can be found by sampling the input data as originally coded. Type-2 problems, we suggest, present neither rare nor pathological cases. They are rife in biologically realistic settings and in domains ranging from simple animat behaviors to language acquisition. Not only are such problems rife – they are standardly solved! This presents a puzzle. How, given the statistical intractability of these type-2 cases, does nature turn the trick? One answer, which we do not pursue, is to suppose that evolution gifts us with exactly the right set of recoding biases so as to reduce specific type-2 problems to type-1 mappings. Such a heavy-duty nativism is no doubt sometimes plausible. But we believe there are other, more general mechanisms also at work. Such mechanisms provide general strategies for managing problems of type-2 complexity. Several such mechanisms are investigated. At the heart of each is a fundamental ploy – namely, the maximal exploitation of states of representation already achieved by prior, simpler learning so as to reduce the amount of subsequent computational search. Such exploitation both characterizes and helps make unitary sense of a diverse range of mechanisms. These include simple incremental learning, modular connectionism, and the developmental hypothesis of “representational redescription”. In addition, the most distinctive features of human cognition – language and culture – may themselves be viewed as adaptations enabling this representation/computation trade-off to be pursued on an even grander scale.

We compare and contrast two recent, but interestingly divergent, accounts of the place of forward models in the human cognitive architecture.

On the Integral Forward Model account, forward models lie at the heart of all forms of perception and action. We compare these neighbouring (...) but importantly different visions and consider their implications for the cognitive sciences. We end by asking what kinds of empirical research might offer evidence favouring one or the other of these approaches. (shrink)

It's a presupposition of a very common way of thinking about contextsensitivity in language that the semantic contribution made by a bit of context-sensitive vocabulary is sensitive only to features of the speaker's situation at the time of utterance.
