Throughout his career David Hull has sought to bring the philosophy of science into closer contact with science and especially with biological science (Hull 1969, 1997b). This effort has taken many forms. Sometimes it has meant ‘either explaining basic biology to philosophers or explaining basic philosophy to biologists’ (Hull 1996, p. 77). The first of these tasks, simple as it sounds, has been responsible for revolutionary changes. It is well known that traditional philosophy of science, modeled as it was on (...) theoretical physics, proved inadequate when philosophers turned their attention to biological science. Biological examples have driven major revisions of accounts of reduction (Hull 1974; Schaffner 1993, Ch. 9), laws of nature (Beatty et al. 1997), theories (Lloyd 1988) and natural kinds (Wilson 1999, Part III). Nor is explaining basic philosophy to biologists a task to be looked down upon. It is useful, not because philosophy has all the answers, but because scientists must think about how to do science, that is doing philosophy of science and scientists frequently reinvent philosophical views with known flaws. Early in his career Hull found biological systematists in the grip of a crude operationalism about scientific concepts and said so in the pages of Systematic Zoology (Hull 1968). For the next thirty years, as biologists debated the nature of species and the correct principles of classification, Hull added a philosophical note at the same congresses and in the same journals (Hull 1970, 1976, 1980, 1997a, 1999).

The anterior cingulate cortex (ACC)has been identified as part of a supervisoryattentional network for selecting alternativemotor programs in response to top-down corticalprocessing, particularly in situationsinvolving conflicting cognitive tasks.Bilateral lesions to the ACC may be causallyassociated with akinetic mutism, where patientsare unable to voluntarily initiate responses.The clinical and neuroanatomical evidence forthis presumed causal association is examined atlength. However, given the many reciprocalprojections between cerebral, motor, limbic andparalimbic structures within the executivesupervisory network, the association ofvoluntary behavior with a particular structure(the ACC) is (...) highly controversial and thereforepremature at this time. Also considered is theclaim that our subjective sense of voluntarycontrol and free will is simply due toour not having conscious access to theunderlying neural computations that precede our decisions and actions. On thecontrary, the distinction between voluntary and involuntary thoughts and actions mayrather be a matter of temporal and directionallag between parallel computations in differentneural areas. Finally, with reference toDennett, there is an extended discussion ofwhether patients with akinetic mutism are (i) conscious automata, (ii) non-intentional systems, and (iii) in azombie-like state. The relevance of (i)–(iii) for the cognitive neuroscientificliterature is then briefly addressed. (shrink)

Teaching at a private, conservative religious institution poses unique challenges for equality, diversity, and inclusivity education (EDI). Given the realities of the student population in the Honors College of a private, religious institution, it is necessary to first introduce students to the contemporary realities of inequality and oppression and thus the need for EDI. This chapter proposes a conceptual framework and pedagogical suggestions for teaching basic concepts of social justice in a team-taught, interdisciplinary social science course. The course integrates four (...) different approaches to justice: theoretical, social scientific, narratological, and experiential. The discussion of the experiential dimension of the course references practical pedagogical strategies for making social justice and inequality real for our students. Understanding the realities of social inequality and its roots can foster a better understanding of the social forces and structures that perpetuate inequality. Furthermore, this approach can plant the intellectual and empathic seeds to challenge in-group bias and hopefully germinate into fruitful interaction with diverse others. Finally, this rich, interdisciplinary encounter with social inequality and justice can prepare students to work for just social structures that will lead to a more inclusive world. (shrink)

Do the previous termviewpoint costsnext term incurred when naming rotated familiar objects arise during initial identification or during previous termconsolidation?next term To answer this question we employed an attentional blink (AB) task where two target objects appeared amongst a rapid stream of distractor objects. Our assumption was that while both targets and distractors undergo initial identification only targets are consolidated in a form that allows overt report. We presented line drawings of objects with a usual upright canonical orientation, and separately (...) manipulated the orientation of targets and distractors. In two experiments, targets were defined by colour, whereas in a third experiment they were defined by semantic category. Target 1 orientation influenced the AB, with objects rotated by 90° causing a larger second target deficit than upright and upside-down objects. However, distractor orientation did not affect the magnitude of the second target deficit, regardless of whether targets were defined by colour or semantic category. Taken together, these findings suggest that the visual representations involved in the preliminary recognition of familiar objects are previous termviewpointnext term-invariant and that previous termviewpoint costsnext term are incurred when these objects are consolidated for report.

The question of whether object recognition is orientation-invariant or orientation-dependent was investigated using a repetition blindness (RB) paradigm. In RB, the second occurrence of a repeated stimulus is less likely to be reported, compared to the occurrence of a different stimulus, if it occurs within a short time of the first presentation. This failure is usually interpreted as a difficulty in assigning two separate episodic tokens to the same visual type. Thus, RB can provide useful information about which representations are (...) treated as the same by the visual system. Two experiments tested whether RB occurs for repeated objects that were either in identical orientations, or differed by 30, 60, 90, or 180°. Significant RB was found for all orientation differences, consistent with the existence of orientation-invariant object representations. However, under some circumstances, RB was reduced or even eliminated when the repeated object was rotated by 180°, suggesting easier individuation of the repeated objects in this case. A third experiment confirmed that the upside-down orientation is processed more easily than other rotated orientations. The results indicate that, although object identity can be determined independently of orientation, orientation plays an important role in establishing distinct episodic representations of a repeated object, thus enabling one to report them as separate events.

Using Virgil’s Aeneid VI as an example, this paper explores what might become of language and “truth” if contrary to Plato’s proposed course of education for the guardians of the state one moves, not up from sense perceptions to univocal, intelligible being, but down to the ambiguous realm of sleep, dreams and death.

Arguing About Human Nature covers recent debates--arising from biology, philosophy, psychology, and physical anthropology--that together systematically examine what it means to be human. Thirty-five essays--several of them appearing here for the first time in print--were carefully selected to offer competing perspectives on 12 different topics related to human nature. The context and main threads of the debates are highlighted and explained by the editors in a short, clear introduction to each of the 12 topics. Authors include Louise Anthony, Patrick Bateson, (...) David Buller, John Dupre, Paul Griffiths, Sally Haslanger, Richard Lewontin, Ron Mallon, and E.O. Wilson. Contributors Rachel Cooper, Nancy Holmstrom, Kim Sterelny, and Elizabeth Cashdan provide brand new chapters in these debates. Suggested Reading lists offer curious readers new resources for exploring these debates further. A rguing About Human Nature is the first volume of its kind, designed to introduce to an interdisciplinary student audience some of the most important arguments on the subject generated by scientific research and philosophical reflection.

A general conceptual framework for large-scale neocortical dynamics based on data from many laboratories is applied to a variety of experimental designs, spatial scales, and brain states. Partly distinct, but interacting local processes (e.g., neural networks) arise from functional segregation. Global processes arise from functional integration and can facilitate (top down) synchronous activity in remote cell groups that function simultaneously at several different spatial scales. Simultaneous local processes may help drive (bottom up) macroscopic global dynamics observed with electroencephalography (EEG) or (...) magnetoencephalography (MEG). A local/global dynamic theory that is consistent with EEG data and the proposed conceptual framework is outlined. This theory is neutral about properties of neural networks embedded in macroscopic fields, but its global component makes several qualitative and semiquantitative predictions about EEG measures of traveling and standing wave phenomena. A more general “metatheory” suggests what large-scale quantitative theories of neocortical dynamics may be like when more accurate treatment of local and nonlinear effects is achieved. The theory describes the dynamics of excitatory and inhibitory synaptic action fields. EEG and MEG provide large-scale estimates of modulation of these synaptic fields around background levels. Brain states are determined by neuromodulatory control parameters. Purely local states are dominated by local feedback gains and rise and decay times of postsynaptic potentials. Dominant local frequencies vary with brain region. Other states are purely global, with moderate to high coherence over large distances. Multiple global mode frequencies arise from a combination of delays in corticocortical axons and neocortical boundary conditions. Global frequencies are identical in all cortical regions, but most states involve dynamic interactions between local networks and the global system. EEG frequencies may involve a “matching” of local resonant frequencies with one or more of the many, closely spaced global frequencies. Key Words: binding problem; cell assemblies; coherence; EEG; limit cycles; neocortical dynamics; pacemakers; phase locking; spatial scale; standing waves; synchronization.

In lieu of an abstract, here is a brief excerpt of the content:Three Ovidian Tails PAUL BAROLSKY Kneeling at the edge of a pond in push-up position, a beautiful nude boy crowned with flowers gazes down at the water in which he beholds his reflection. In love, he is enthralled. Thus, the image of Narcissus rendered by the Florentine painter Alessandro Allori in a work that has been largely overlooked until recently. Datable to the second half of the sixteenth (...) century, it now hangs in the Turkish Embassy in Washington, DC. In the distant background of the picture we behold Echo, who extends an arm upward seemingly in a gesture of despair, since she is rejected by Narcissus. She stands before a mass of rock, her left leg beginning to turn to stone, the very stone into which she vanishes as only her voice remains when she echoes her beloved. The painting abounds in Alessandro Allori, Narcissus.

There are other notable details such as the crab on a rock in the foreground, or the clusters of pendulous, ripe grapes, fruit of Bacchus, to whom androgynous Narcissus is likened in Ovid’s Metamorphoses. Allori also employs poetic simile in his picture, since the fingers of the youth’s left hand rhyme with the finger-like roots that emerge from the water. These roots are magnified in turn by their reflected image on the water’s surface. 136 three ovidian tails Abraham Janssens, Nymph and Pan Among the Reeds. AKG / Museen Böttcherstra ße. The apex of the picture, we might say, is baby Cupid who, hovering above, aims his dart at Narcissus and thus arouses the boy’s desire. The shape of Cupid’s bow echoes that of Narcissus ’s prominent buttocks which are framed by the attractive, bright golden drapery fluttering prominently around the youth’s posterior. One might well say that Allori features the buttocks of Narcissus’s body most provocatively in a kind of butt which recalls that of Cupid in the famous Venus, Cupid, Folly, and Time painted by the artist’s teacher, Bronzino. What Allori pictures is not exactly what Ovid writes. It is, however, how Allori imagines the Narcissus of Ovid’s tale. Allori is not alone among Ovidian artists in focusing on the backside of the human body. The posterior is especially prominent in another mythological picture, this one from the early seventeenth century, executed by a disciple of Rubens, Abraham Janssens. This work has found its way to Bremen, where it is now housed in the Ludwig Roselius Museum. It illustrates Pan’s pursuit of Syrinx, who is metamorphosed into reeds in a story told by Mercury in order to put Argus asleep. Ovid is Janssens’s point of departure. The artist depicts the moment when a muscular Pan with a ruddy, almost leathery face embraces Syrinx in her new form as a bunch of reeds. Janssens departs from Ovid with a most novel invention. He depicts a woman, seen from behind, who dominates the composition. With sharp contrasts of lights and darks, vestiges of Caravaggio, the painter emphasizes the female’s imposingly broad backside, which is framed by a billowing, bright, attention-grabbing red drapery that she seems to hold across the front of her body. Could it be that Janssens here alludes to the backside of Syrinx as Pan would have seen it when he chased her? It would seem that we are given not only a view of Pan embracing reeds, we are simultaneously given a Pan’s-eye view of Syrinx’s prominent and provocative backside before her metamorphosis. I wish to consider one final example of the derrière in Ovidian art, this one prominent in a picture painted well Paul Barolsky 137 over a hundred years after Janssens worked: Louis-JeanFran çois Lagrenée’s Abduction of Deianira by the Centaur Nessus, a work which is now in the Louvre.

Afrocentrism. Eurocentrism. Caribbean Studies. British Studies. To the forces of cultural nationalism hunkered down in their camps, this bold hook sounds a liberating call. There is, Paul Gilroy tells us, a culture that is not specifically African, American, Caribbean, or British, but all of these at once, a black Atlantic culture whose themes and techniques transcend ethnicity and nationality to produce something new and, until now, unremarked. Challenging the practices and assumptions of cultural studies, The Black Atlantic also complicates (...) and enriches our understanding of modernism. Debates about postmodernism have cast an unfashionable pall over questions of historical periodization. Gilroy bucks this trend by arguing that the development of black culture in the Americas arid Europe is a historical experience which can be called modern for a number of clear and specific reasons. For Hegel, the dialectic of master and slave was integral to modernity, and Gilroy considers the implications of this idea for a transatlantic culture. In search of a poetics reflecting the politics and history of this culture, he takes us on a transatlantic tour of the music that, for centuries, has transmitted racial messages and feeling around the world, from the Jubilee Singers in the nineteenth century to Jimi Hendrix to rap. He also explores this internationalism as it is manifested in black writing from the "double consciousness" of W. E. B. Du Bois to the "double vision" of Richard Wright to the compelling voice of Toni Morrison. In a final tour de force, Gilroy exposes the shared contours of black and Jewish concepts of diaspora in order both to establish a theoretical basis for healing rifts between blacks and Jews in contemporary culture and to further define the central theme of his book: that blacks have shaped a nationalism, if not a nation, within the shared culture of the black Atlantic.

.Evolutionary analysis focuses on how genes build organisms with different strategies for engaging and solving life’s challenges of survival and reproduction. One of those challenges is competing with conspecifics for limited resources including reproductive opportunities. This article will suggest that there is now good evidence for considering two dimensions of social competition. First, we will label antisocial strategies, to the extent that they tend to be self-focused, threat sensitive and aggressive, as well as using tactics of bulling, threatening, intimidating or (...) even injuring/killing competitors. Their strategic goal is to stimulate fear-inhibition, flight or submissive compliance in subordinates. Such strategies turn off and inhibit care and affiliative social interactions and motivation and they can be enacted by parents, teachers and leaders. The social signals emitted stimulate various aspects of threat processing in recipients, create stressful and highly stratified groups with a range of detrimental psychological and physiological effects. Second, in contrast, prosocial strategies seek to create relaxed and secure social interactions that enable sharing, cooperative and mutually supportive and beneficial relationships. The friendly and low/no threat social signals emitted in friendly cooperative and affiliative relationships stimulate physiological systems (e.g., oxytocin, the vagus parasympathetic system) that down regulates threat processing, enhances the immune system, facilitates frontal cortical processes and general wellbeing. This article reviews the literature pertaining to the evidence for these two dimensions of social engagement. (shrink)

In this paper, I examine how a manifest disagreement between Richard Rorty and Alasdair MacIntyre concerning the history of philosophy is but one of a series of deep and interrelated disagreements concerning, in addition, the history of science, the good life for human beings, and, ultimately, the character of and prospects for humankind as well. I shall argue that at the heart of this series of disagreements rests a dispute with regard to the nature of rationality. And this disagreement concerning (...) the norms of rationality, despite its theoretical and practical importance, is one which is, or so I argue, irresolvable. Moreover, the series of disagreements which I examine in the context of the debate between Rorty and MacIntyre is not peculiar or idiosyncratic to them. Their dispute reflects presumptions common to contemporary analytical philosophy. And while analytical philosophers have not made discussions of human nature one of their characteristic concerns, I indicate that such concerns do play a central role in the controversy which I examine. Differences of opinion concerning the political and social nature of human beings are reflected up and down the philosophical line. My argument is in no way concerned with issues of psychological priority or causality (e.g. whether having certain views disposes one psychologically to accepting other views). What I establish are the logical relations, and the points of philosophical contention, among certain epistemo logical and political theses. In Part I, I rehearse Rorty's epistemological views and examine how these views are connected to his views on morality and human nature. In Part II, I begin with MacIntyre's position concerning the virtues and modern moral philosophy and then reconstruct, ex pede Herculem, his views on rationality. Part III examines the prospects of reconciling the perspectives discussed in the first two sections. (shrink)

Thought experiments play a prominent role in philosophical inquiry. And yet we lack a good understanding of how they work and how they are supposed to supply evidence or knowledge in inquiry. This dissertation offers a novel account of the epistemology of philosophical thought experiments, namely, the reason-responsiveness view. The view is inspired by a virtue ethical tradition that flowers in John McDowell (1994) and Miranda Fricker (2007). Drawing on this virtue ethical tradition, I argue that knowing in philosophical thought (...) experiments is achieved through the exercise of the virtue of sensibility, which has three distinct features. First, it is social in origin, acquired through our training in a human language and as ordinary members of a community. Second, it is recognitional in the sense that although our sensibility gives us the ability to classify situations, whether real or hypothetical and to resonate with rational considerations for or against a given classificational judgement (i.e., the judgements we form in thought experiments), it does not equip us with a reflective ability to fully articulate those reasons in an infallible way. And third, it allows us to project across various contexts, both in real and in hypothetical situations. And this ability to project, I argue further, does not come from the ability of people to grasp concepts or to have certain mental episodes or phenomenology or to grasp universals or to have mastery of the application conditions of rules or from belonging to some exclusive club or from enjoying a certain superior access to concepts or access to philosophically interesting phenomena not available to ordinary people. On the contrary, that we do comes down to “our sharing routes of interest and feeling, mode of response, senses of humour and of significance, of what is outrageous, of what is similar to what else, what a rebuke, what forgiveness, of when an utterance is an assertion, when an appeal, when an explanation—all the while of organism Wittgenstein calls “forms of life” (Cavell, 1969, p.52). The account is then used to shore up the claim of epistemological continuity, which asserts that the epistemology of thought experiments is an extension of social cognition or social epistemology (Cappelen, 2012; Deutsch, 2015; Williamson 2007), and to offer a claim of epistemological-continuity-style defence of philosophical thought experiments against two major objections in the literature, namely, the negative experimentalist challenge (see Machery, 2017) and the ordinary language challenge ( Baz, 2016, 2017).

I. A. Richards ushered the spirit of Cambridge realism into semantics and literary criticism. When he arrived as an undergraduate in 1911, Cambridge was in the midst of its finest philosophical flowering since the Puritanism and Platonism of the seventeenth century. The revolution of G. E. Moore and Bertrand Russell against Hegelian idealism had already occurred; the Age of Principia was under way. There was a reassertion of native empiricism and a new interest in philosophical psychology, and the whole discussion (...) was marked increasingly by a preoccupation with language. Richards, too, would break with the past, with the history of criticism in the previous two generations, gather psychological ideas to establish an empirical semantics and aesthetics, and center his attention on language. Although Romantic and late-Victorian values inform his theories, Richards set down an original criticism on first principles, not on tradition. Many of his books' titles show this rationalist strains: The Foundations of Aesthetics , The Meaning of Meaning , Principles of Literary Criticism , Basic Rules of Reason , and The Philosophy of Rhetoric . The originality and influence of Richards' criticism can be shown by the number of terms he put into circulation, terms which became the currency of debate for almost half a century: close reading, tone, pseudostatement, stock response, tension, equilibrium, tenor and vehicle of metaphor, emotive and referential language.John Paul Russo is a professor and chairman of the English department at the University of Miami. He is the editor of I. A. Richards' Complementarities: Uncollected Essays and the author of Alexander Pope: Tradition and Identity and an annotated bibliography of Richards' works. He is currently completing a critical biography of Richards. "A Study in Influence: The Moore-Richards Paradigm," his previous contribution to Critical Inquiry, appeared in the Summer 1979 issue.

The last phase of Greek philosophy has until recently been less intelligently studied than any other, and in our understanding of its development there are still lamentable lacunae. Three errors in particular have in the past prevented a proper appreciation of Plotinus' place in the history of philosophy. The first was the failure to distinguish Neoplatonism from Platonism: this vitiates the work of many early exponents from Ficinus down to Kirchner. The second was the belief that the Neoplatonists, being ‘mystics,’ (...) were necessarily incomprehensible to the plain man or even to the plain philosopher. To have encouraged the persistence of this superstition in the nineteenth century is the least pardonable of Creuzer's many sins. The third was the chronological confusion involved in the ascription to Saint Paul's contemporary of the works of the pretended Dionysius Areopagita, which contain a fully-developed Neoplatonic theology. Though the fraud had been exposed by Scaliger, these writings continued down to the beginning of the nineteenth century to be used as evidence that the ‘Nsoplatonic trinity’ was an inferior imitation of the Christian one. When this false trail was at length abandoned the fashion for orientalizing explanations persisted in another guise: to the earliest historians of Neoplatonism, Simon and Vacherot, the school of Plotinus was ‘the school of Alexandria,’ and its inspiration was mainly Egyptian. Vacherot says of Neoplatonism that it is ‘essentially and radically oriental, having nothing of Greek thought but its language and procedure.’ Few would be found to-day to subscribe to so sweeping a pronouncement; but the existence of an important oriental element in Plotinus' thought is still affirmed by many French and German writers.

Many of the most important properties of human groups – including properties that may give one group an evolutionary advantage over another – are properly defined only at the level of group organization. Yet at present, most work on the evolution of culture has focused solely on the transmission of individual-level traits. I propose a conceptual extension of the theory of cultural evolution, particularly related to the evolutionary competition between cultural groups. The key concept in this extension is the emergent (...) group-level trait. This type of trait is characterized by the structured organization of differentiated individuals and constitutes a unit of selection that is qualitatively different from selection on groups as defined by traditional multilevel selection theory. As a corollary, I argue that the traditional focus on cooperation as the defining feature of human societies has missed an essential feature of cooperative groups. Traditional models of cooperation assume that interacting with one cooperator is equivalent to interacting with any other. However, human groups involve differential roles, meaning that receiving aid from one individual is often preferred to receiving aid from another. In this target article, I discuss the emergence and evolution of group-level traits and the implications for the theory of cultural evolution, including ramifications for the evolution of human cooperation, technology, and cultural institutions, and for the equivalency of multilevel selection and inclusive fitness approaches.

In the face of growing skepticism and relativism, “believe in reason” is the central message in Pope John Paul II’s Fides et Ratio. Only by the two wings of reason and faith together can the human spirit soar. The current work, Ratio et Fides, is its philosophical counterpart. It is not a watered-down introduction but a “leading-into” the heart of philosophic thinking. Firmly rooted in the phenomenological description of an ordinary artifact, a mailbox, the book uses the principles involved (...) in the description to examine key figures in the history of thought. We focus on three areas: the Soul, Morality, and God. We consider seven thinkers. Plato and Aristotle, who founded the tradition, were taken up by Augustine and Aquinas in developing their theologies. Descartes launched the distinctively modern tradition, culminating in Hegel’s systematic presentation of the whole Western tradition, philosophical and religious. More recently, Heidegger approached that tradition in terms of its hidden ground in the Mystery of Being, recalling us to meditative thinking as the secular counterpart to prayer. Armed with this background, students will be able to approach with profit the Fathers of the Church and major theologians and philosophers, past and recent. (shrink)

In this paper, the authors show that there is a reading of St. Anselm's ontological argument in Proslogium II that is logically valid (the premises entail the conclusion). This reading takes Anselm's use of the definite description "that than which nothing greater can be conceived" seriously. Consider a first-order language and logic in which definite descriptions are genuine terms, and in which the quantified sentence "there is an x such that..." does not imply "x exists". Then, using an ordinary logic (...) of descriptions and a connected greater-than relation, God's existence logically follows from the claims: (a) there is a conceivable thing than which nothing greater is conceivable, and (b) if <em>x</em> doesn't exist, something greater than x can be conceived. To deny the conclusion, one must deny one of the premises. However, the argument involves no modal inferences and, interestingly, Descartes' ontological argument can be derived from it. (shrink)

The etiological approach to ‘proper functions’ in biology can be strengthened by relating it to Robert Cummins' general treatment of function ascription. The proper functions of a biological trait are the functions it is assigned in a Cummins-style functional explanation of the fitness of ancestors. These functions figure in selective explanations of the trait. It is also argued that some recent etiological theories include inaccurate accounts of selective explanation in biology. Finally, a generalization of the notion of selective explanation allows (...) an analysis of the proper functions of human artifacts. (shrink)

Some ‘naturalist’ accounts of disease employ a biostatistical account of dysfunction, whilst others use a ‘selected effect’ account. Several recent authors have argued that the biostatistical account offers the best hope for a naturalist account of disease. We show that the selected effect account survives the criticisms levelled by these authors relatively unscathed, and has significant advantages over the BST. Moreover, unlike the BST, it has a strong theoretical rationale and can provide substantive reasons to decide difficult cases. This is (...) illustrated by showing how life-history theory clarifies the status of so-called diseases of old age.

In behavioral ecology some authors regard the innateness concept as irretrievably confused whilst others take it to refer to adaptations. In cognitive psychology, however, whether traits are 'innate' is regarded as a significant question and is often the subject of heated debate. Several philosophers have tried to define innateness with the intention of making sense of its use in cognitive psychology. In contrast, I argue that the concept is irretrievably confused. The vernacular innateness concept represents a key aspect of 'folkbiology', (...) namely, the explanatory strategy that psychologists and cognitive anthropologists have labeled 'folk essentialism'. Folk essentialism is inimical to Darwinism, and both Darwin and the founders of the modern synthesis struggled to overcome this way of thinking about living systems. Because the vernacular concept of innateness is part of folkbiology, attempts to define it more adequately are unlikely to succeed, making it preferable to introduce new, neutral terms for the various, related notions that are needed to understand cognitive development.

Because physical theories typically predict numerical values, an improvement in experimental precision reduces the tolerance range and hence increases corroborability. In most psychological research, improved power of a statistical design leads to a prior probability approaching 1/2 of finding a significant difference in the theoretically predicted direction. Hence the corroboration yielded by "success" is very weak, and becomes weaker with increased precision. "Statistical significance" plays a logical role in psychology precisely the reverse of its role in physics. This problem is (...) worsened by certain unhealthy tendencies prevalent among psychologists, such as a premium placed on experimental "cuteness" and a free reliance upon ad hoc explanations to avoid refutation.

Several authors have argued that causes differ in the degree to which they are ‘specific’ to their effects. Woodward has used this idea to enrich his influential interventionist theory of causal explanation. Here we propose a way to measure causal specificity using tools from information theory. We show that the specificity of a causal variable is not well-defined without a probability distribution over the states of that variable. We demonstrate the tractability and interest of our proposed measure by measuring the (...) specificity of coding DNA and other factors in a simple model of the production of mRNA. (shrink)

We outline three very different concepts of the gene—instrumental, nominal, and postgenomic. The instrumental gene has a critical role in the construction and interpretation of experiments in which the relationship between genotype and phenotype is explored via hybridization between organisms or directly between nucleic acid molecules. It also plays an important theoretical role in the foundations of disciplines such as quantitative genetics and population genetics. The nominal gene is a critical practical tool, allowing stable communication between bioscientists in a wide (...) range of fields grounded in well-defined sequences of nucleotides, but this concept does not embody major theoretical insights into genome structure or function. The post-genomic gene embodies the continuing project of understanding how genome structure supports genome function, but with a deflationary picture of the gene as a structural unit. This final concept of the gene poses a significant challenge to conventional assumptions about the relationship between genome structure and function, and between genotype and phenotype. (shrink)

Human experts are the source of knowledge required to develop computer systems that perform at an expert level. Human beings are not, however, able to reliably express what they know. As a result, experts often develop non-authentic accounts of their own expertise. These accounts, here termed reconstructed methods of reasoning, lead to computer systems that perform at a high level of proficiency but have the disadvantage that they often do not reflect the heuristics and processing constraints of a system user. (...) Reconstructed methods of reasoning are compared with authentic methods derived from the study of expert human behavior. Tests are proposed to establish the authenticity of reasoning methods and examples from medical diagnosis are used to illustrate how authentic methods of reasoning can be incorporated into an expert computer system.

In earlier work I have claimed that emotion and some emotions are not `natural kinds'. Here I clarify what I mean by `natural kind', suggest a new and more accurate term, and discuss the objection that emotion and emotions are not descriptive categories at all, but fundamentally normative categories.

It is unreasonable to assume that our pre-scientific emotion vocabulary embodies all and only those distinctions required for a scientific psychology of emotion. The psychoevolutionary approach to emotion yields an alternative classification of certain emotion phenomena. The new categories are based on a set of evolved adaptive responses, or affect-programs, which are found in all cultures. The triggering of these responses involves a modular system of stimulus appraisal, whose evoluations may conflict with those of higher-level cognitive processes. Whilst the structure (...) of the adaptive responses is innate, the contents of the system which triggers them are largely learnt. The circuits subserving the adaptive responses are probably located in the limbic system. This theory of emotion is directly applicable only to a small sub-domain of the traditional realm of emotion. It can be used, however, to explain the grouping of various other phenomena under the heading of emotion, and to explain various characteristic failings of the pre-scientific conception of emotion.

I defend the view that many biological categories are defined by homology against a series of arguments designed to show that all biological categories are defined, at least in part, by selected function. I show that categories of homology are `abnormality inclusive'—something often alleged to be unique to selected function categories. I show that classifications by selected function are logically dependent on classifications by homology, but not vice-versa. Finally, I reject the view that biologists must use considerations of selected function (...) to abstract away from variation and pathology to form a canonical description of a class of biological systems.

Kenneth C. Schaffner's paper is an important contribution to the literature on behavioral genetics and on genetics in general. Schaffner has a long record of injecting real molecular biology into philosophical discussions of genetics. His treatments of the reduction of Mendelian to molecular genetics first drew philosophical attention to the problems of detail that have fuelled both anti-reductionism and more sophisticated models of theory reduction. An injection of molecular detail into discussions of genetics is particularly necessary at the present time, (...) when so many philosophers seem happy to discuss the philosophical and ethical implications of molecular biology using gene concepts derived from evolutionary biology ). Schaffner has long advocated the view that the philosophy of biology should be more than the philosophy of evolution. This paper shows how radically a picture of gene action derived from molecular biology undercuts the popular picture associated with a more evolutionary view of genes as units of heredity or as ‘difference-makers’ mediated by the ‘black box’ of development.

A number of philosophers and ‘evolutionary psychologists’ have argued that attacks on adaptationism in contemporary biology are misguided. These thinkers identify anti-adaptationism with advocacy of non-adaptive modes of explanation. They overlook the influence of anti-adaptationism in the development of more rigorous forms of adaptive explanation. Many biologists who reject adaptationism do not reject Darwinism. Instead, they have pioneered the contemporary historical turn in the study of adaptation. One real issue which remains unresolved amongst these methodological advances is the nature of (...) ‘phylogenetic inertia’. To what extent is an adaptive explanation needed for the persistence of a trait as well as its origin? (shrink)

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? In this chapter we apply this argument to beliefs in three different domains: morality, religion, and science. We identify replies to evolutionary scepticism that work in some domains but not in others. The simplest reply to evolutionary scepticism is that the truth of beliefs (...) in a certain domain is, in fact, connected to evolutionary success, so that evolution can be expected to design systems that produce true beliefs in that domain. We call a connection between truth and evolutionary success a ‘Milvian bridge’, after the tradition which ascribes the triumph of Christianity at the battle of the Milvian bridge to the truth of Christianity. We argue that a Milvian bridge can be constructed for commonsense beliefs, and extended to scientific beliefs, but not to moral and religious beliefs. An alternative reply to evolutionary scepticism, which has been used defend moral beliefs, is to argue that their truth does not depend on their tracking some external state of affairs. We ask if this reply could be used to defend religious beliefs. (shrink)
