I try to focus our differences by examining the relation between what Dennett has termed "the intentional stance" and "the design stance." Dennett takes the intentional stance to be more basic than the design stance. Ultimately it is through the eyes of the intentional stance that both human and natural design are interpreted, hence there is always a degree of interpretive freedom in reading the mind, the purposes, both of Nature and of her children. The reason, or at least a (...) reason, is that intentional interpretation is holistic, hence indeterminate, for the kinds of reasons given by Davidson and Quine. In contrast, I take the design stance to be more basic than the intentional stance. Intentional attributions express our best guesses about the locations of effects of certain kinds of natural design. And although there is often indeterminacy, ambiguity, or vagueness concerning what it is that natural selection (or learning) has selected for, these indeterminacies and vaguenesses are local, not holistic. There is reason to suppose that the better portion of Nature's purposes and the intentional states of her children are determinate in content within quite closely defined limits. I propose to defend this position as well as I can, so as to call from Dennett his own views on precisely where our paths separate (if they really do). (shrink)

I give an analysis of how empirical terms do their work in communication and the gathering of knowledge that is fully externalist and that covers the full range of empirical terms. It rests on claims about ontology. A result is that armchair analysis fails as a tool for examining meanings of ‘basic’ empirical terms because their meanings are not determined by common methods or criteria of application passed from old to new users, by conventionally determined ‘intensions’. Nor do methods of (...) application used by individual speakers constitute definitive reference-determining intensions for their idiolect terms or associated concepts. Conventional intensions of non-basic empirical terms ultimately rest on basic empirical concepts, so no empirical meaning is found merely ‘in the head’. I discuss the nature of lexical definition, why empirical meanings cannot ultimately be modelled as functions from possible worlds to extensions, and traps into which armchair analysis of meaning can lead us. A coda explains how ‘Swampman’ examples, as used against teleosemantic theories of content, illustrate such traps. (shrink)

A list of groceries, Professor Anscombe once suggested, might be used as a shopping list, telling what to buy, or it might be used as an inventory list, telling what has been bought (Anscombe 1957). If used as a shopping list, the world is supposed to conform to the representation: if the list does not match what is in the grocery bag, it is what is in the bag that is at fault. But if used as an inventory list, the (...) representation is supposed to conform to the world: if the list does not match what is in the bag, it is the list that is at fault. The first kind of representation, where the world is supposed to conform to the list, can be called "directive"; it represents or directs what is to be done. The second, where the list is supposed to conform to the world, can be called "descriptive"; it represents or describes what is the case. I wish to propose that there exist representations that face both these ways at once. With apologies to Dr. Doolittle, I call them pushmi-pullyu representations or PPRs. (shrink)

"Paleontologists like to say that to a first approximation, all species are extinct (ninety- nine percent is the usual estimate). The organisms we see around us are distant cousins, not great grandparents; they are a few scattered twig-tips of an enormous tree whose branches and trunk are no longer with us." (p. 343-44). The historical life bush consists mainly in dead ends.

Brentano was surely mistaken, however, in thinking that bearing a relation to something nonexistent marks only the mental. Given any sort of purpose, it might not get fulfilled, hence might exhibit Brentano's relation, and there are many natural purposes, such as the purpose of one's stomach to digest food or the purpose of one's protective eye blink reflex to keep out the sand, that are not mental, nor derived from anything mental. Nor are stomachs and reflexes "of" or"about" anything. A (...) reply might be, I suppose, that natural purposes are "purposes" only in an analogical sense hence "fail to be fulfilled" only in an analogical way. They bear an analogy to things that have been intentionally designed by purposive minds, hence can fail to accomplish the purposes they analogically have. As such they also have only analogical "intentionality". Such a response begs the question, however, for it assumes that natural purposes are not purposes in the full sense exactly because they are not. (shrink)

I sketch in miniature the whole of my work on the relation between language and thought. Previously I have offered closeups of this terrain in various papers and books, and I reference them freely. But my main purpose here is to explain the relations among the parts, hoping this can serve as a short introduction to my work on language and thought for some, and for others as a clarification of the larger plan.

Steven Pinker (1995) chides the educated layman for imagining Darwin's theory to go this way (the vertical lines are "begats"): [Figure #1] Pinker says, "evolution did not make a ladder; it made a bush" (p. 343), and he gives us the following diagrams instead, showing how it went, in increasing detail, down to us.

"According to informational semantics, if it's necessary that a creature can't distinguish Xs from Ys, it follows that the creature can't have a concept that applies to Xs but not Ys." (Jerry Fodor, The Elm and the Expert, p.32).

On Reading Signs; Some Differences between Us and The Others If there are certain kinds of signs that an animal cannot learn to interpret, that might be for any of a number of reasons. It might be, first, because the animal cannot discriminate the signs from one another. For example, although human babies learn to discriminate human speech sounds according to the phonological structures of their native languages very easily, it may be that few if any other animals are capable (...) of fully grasping the phonological structures of human languages. If an animal cannot learn to interpret certain signs it might be, second, because the decoding is too difficult for it. It could be, for example, that some animals are incapable of decoding signs that exhibit syntactic embedding, or signs that are spread out over time as opposed to over space. Problems of these various kinds might be solved by using another sign system, say, gestures rather than noises, or visual icons laid out in spatial order, or by separating out embedded propositions and presenting each separately. But a more interesting reason that an animal might be incapable of understanding a sign would be that it lacked mental representations of the necessary kind. It might be incapable of representing mentally what the sign conveys. When discussing what signs animals can understand or. (shrink)

This interview deals with the major themes in the work of Ruth Millikan. Her most fundamental idea is that the intentionality of inner and outer representations can be understood in analogy to biological functions. Another innovative feature is the view that thought and language stand parallel to each other. Thirdly, the basic ideas concerning the ontology and the epistemology of concepts are explained. Millikan aims at clarifying her position by contrasting it with Dretske, Fodor, Sellars, and Brandom. Finally, the (...) interview addresses topics that pose problems for her account as well as questions she does not treat in her work. (shrink)

There is, indeed, a form of informational semantics that has this verificationist implication. The original definition of information given in Dretske's Knowledge and the Flow of Information (1981, hereafter KFI), when employed as a base for a theory of intentional representation or "content," has this implication. I will argue that, in fact, most of what an animal needs to know about its environment is not available as natural information of this kind. It is true, I believe, that there is one (...) fundamental kind of perception that depends on this kind of natural information, but more sophisticated forms of inner representation do not. It is unclear, however, exactly what "natural information" is supposed to mean, certainly in Fodor's, and even in Dretske's writing. In many places, Dretske seems to employ a softer notion than the one he originally defines. I will propose a softer view of natural information that is, I believe, at least hinted at by Dretske, and show that it does not have verificationist consequences. According to this soft informational semantics, a creature can perfectly well have a representation of Xs without being able to discriminate Xs from Ys. (shrink)

Philosophers and laymen alike have traditionally assumed that whether you can reason well, make valid inferences, avoid logical mistakes and so forth is entirely a matter of how well the cogs in your head are fashioned and oiled. Partner to this is the assumption that careful reflection is always the method by which we discover whether an inference or reasoning process is correct. Against this, I argue that good reasoning needs constant empirical support; conceptual clarity is not an a priori, (...) but a deeply empirical matter. Moreover, clear thinking is possible only as embedded in a cooperative external world. (shrink)

Professor Elder has, I believe, misunderstood my position on the ontology of individuals, for I am not any kind of stage theorist. I do indeed believe, however, that there is a sense in which many different things can be in the same place at once, though it is not a sense in which “thing” is a count noun. To explain this, I briefly describe what I call “substances”, a category that includes both individuals and real kinds.

ABSTRACT The expansion of health research to low and middle income countries has increased the likelihood of exploitation and undue influence in economically vulnerable populations. In behavioral research, “reasonable availability”, which was originally developed for biomedical research and advocates for the equitable provision of any product developed during the research process, cannot always prevent exploitation. In such cases and settings, the informed consent process may lack cross-cultural validity and therapeutic misconceptions may arise. This article advocates for a mutual learning framework (...) where international researchers can gain cultural competence while training and empowering local partners, increasing community ownership of health research.

Construction of the trunk/caudal region of the vertebrate embryo involves a set of distinct molecules and processes whose relationships are just coming into focus. In addition to the subdivision of the embryo into head and trunk domains, this “caudalisation” process requires the establishment and maintenance of a stem zone. This sequentially generates caudal tissues over a long period which then undergo differentiation and patterning in the extending body axis. Here we review recent studies that show that changes in the signalling (...) properties of the paraxial mesoderm act as a switch that controls onset of differentiation and pattern in the spinal cord. These findings identify distinct roles for different caudalising factors; in particular, Fibroblast Growth Factor (FGF) inhibits differentiation in the caudal stem zone, while Retinoic acid (RA) provided rostrally by somitic mesoderm is required for neuronal differentiation and establishment of ventral neural pattern. Furthermore, the mutual opposition of FGF and RA pathways controls not only neural differentiation but also mesoderm segmentation and might also underlie the progressive assignment of rostrocaudal identity by regulating Hox gene availability and activation.

Background: There are few standardized measures available to assess executive function in a naturalistic setting for children. The Children’s Cooking Task is a complex test that has been specifically developed to assess EF in a standardized open-ended environment. The aim of the present study was to evaluate the internal consistency, inter-rater reliability, sensitivity and specificity, and also convergent and divergent validity of the Norwegian version of CCT among children with pediatric Acquired Brain Injury and healthy controls.Methods: The present study has (...) a cross-sectional design, based on baseline data derived from a multicenter RCT. Seventy-five children with pABI from two university hospitals with parent-reported executive dysfunction and minimum of 12 months since injury/completed cancer therapy, as well as 59 HCs aged 10–17 years, were assessed with CCT using total errors as the main outcome measure. The pABI group completed tests assessing EF on the impairment level within the ICF framework, and on the participation level. In addition, they completed tests of intellectual ability, processing speed, attention, learning, and memory. Finally, overall functional outcome was evaluated for the children with pABI.Results: Acceptable internal consistency and good inter-rater reliability were found for the CCT. Children with pABI performed significantly worse on the CCT than the HCs. The CCT identified group membership, but the sensitivity and specificity were overall classified as poor. Convergent validity was demonstrated by associations between the CCT and performance-based tests assessing inhibition, cognitive flexibility, and working memory, as well as teacher-reported executive dysfunction. Divergent validity was supported by the lack of association with performance-based measures of learning and memory, attention, and verbal intellectual ability. However, there was a moderate association between the CCT and performance-based tests of processing speed. Lastly, better performance on the CCT was associated with a better functional outcome.Conclusion: Our study with a relatively large sample of children with pABI and HC’s demonstrated good psychometric properties of the CCT. CCT performance was associated with the overall level of disability and function, suggesting that CCT is related to the level of activity in everyday life and participation in society. Hence, our study suggests that the CCT has the potential to advance the assessment of EF by providing a valid analysis of real-world performance. Nevertheless, further research is needed on larger samples, focusing on predictors of task performance, and evaluating the ability of CCT to detect improvement in EF over time. The patterns of error and problem-solving strategies evaluated by the CCT could be used to inform neuropsychological rehabilitation treatmentand represent a more valid outcome measure of rehabilitation interventions.

Background: Despite procedural innovations and increasing numbers of uterus transplant attempts worldwide, the perspectives of uterus transplant (UTx) trial participants are lacking. Methods: We conducted a mixed-methods study with women with absolute uterine factor infertility (AUFI). Participants included women who had previously contacted the Cleveland Clinic regarding the Uterine Transplant Trial and met the initial eligibility criteria for participation. In-depth interviews were conducted in conjunction with FertiQoL, a validated and widely used tool to measure the impact of infertility on the (...) quality of life of infertility patients. Results: All (n = 19) rated their overall health as good; some experienced grief and social isolation. AUFI is a life-framing experience that influences acceptance by family, partners, peers, and one’s self. UTx is a means to gain control of reproductive autonomy. UTx allows family-building and the ability to play an active role in prenatal health and well-being. Establishing and maintaining a supportive relationship is a key issue of AUFI and when considering UTx. Risks of UTx are perceived relative to risks to self/child/family posed by adoption/surrogacy. Participants had no overall preference regarding living or deceased donor. Conclusions: The ways in which women with AUFI conceptualize this condition in their lives and choices around UTx and participating in a study of the procedure are multifaceted and textured. These perspectives are critical to understanding its ethical, legal, and social implications. (shrink)
