This paper examines the relationship between the KK principle and the epistemological theses of externalism and internalism. In particular we examine arguments from Okasha (Analysis 73(1):80–86, 2013) and Greco (J Philos 111(4):169–197, 2014) which deny that we can derive the denial of the KK principle from externalism.

This article argues that mirror neurons originate in sensorimotor associative learning and therefore a new approach is needed to investigate their functions. Mirror neurons were discovered about 20 years ago in the monkey brain, and there is now evidence that they are also present in the human brain. The intriguing feature of many mirror neurons is that they fire not only when the animal is performing an action, such as grasping an object using a power grip, but also when the (...) animal passively observes a similar action performed by another agent. It is widely believed that mirror neurons are a genetic adaptation for action understanding; that they were designed by evolution to fulfill a specific socio-cognitive function. In contrast, we argue that mirror neurons are forged by domain-general processes of associative learning in the course of individual development, and, although they may have psychological functions, they do not necessarily have a specific evolutionary purpose or adaptive function. The evidence supporting this view shows that mirror neurons do not consistently encode action “goals”; the contingency- and context-sensitive nature of associative learning explains the full range of mirror neuron properties; human infants receive enough sensorimotor experience to support associative learning of mirror neurons ; and mirror neurons can be changed in radical ways by sensorimotor training. The associative account implies that reliable information about the function of mirror neurons can be obtained only by research based on developmental history, system-level theory, and careful experimentation.

Commentators have tended to focus on the conceptual framework of our article, the contrast between genetic and associative accounts of mirror neurons, and to challenge it with additional possibilities rather than empirical data. This makes the empirically focused comments especially valuable. The mirror neuron debate is replete with ideas; what it needs now are system-level theories and careful experiments – tests and testability.

The three books presented in this volume, _Integral Humanism_, _Freedom in the Modern World_, and _A Letter on Independence_, were all written in the early 1930s, a time of dire trouble for France. France was then surrounded by enemies preparing for war and was itself so violently split between parties of Left and Right that it seemed on the verge of Civil War. In this collection, Jacques Maritain accepts the responsibility of a Christian philosopher to actively address the agonizing practical (...) problems of the time. Maritain discusses major political issues such as the relation of freedom and religion, the opposition of democracy to any form of totalitarianism, the relation of the spiritual and the temporal, the need for an integral and Christian humanism, and the prospects for a new Christian civilization, all in opposition to the materialism of both communism and capitalism. Against the fierce antagonism of the parties of the political Left and Right, Maritain declares a plague on both their houses and strongly affirms the need for independence from both of them. He does so by distinguishing between two senses of the terms Left and Right, one denoting a temperamental or physiological disposition, the other a definite political position. In the latter sense, Maritain asserts that he is an independent, while acknowledging that he is, by temperament, a man of the Left. (shrink)

A flurry of technological advances in molecular, cellular and developmental biology during the past decade has provided a clearer understanding of mechanisms underlying phenotypic diversification. Building upon such momentum, a recent paper tackles one of the foremost topics in evolution, that is the origin of species‐specific beak morphology in Darwin's finches.1 Previous work involving both domesticated and wild birds implicated a well‐known signaling pathway (i.e. bone morphogenetic proteins) and one population of progenitor cells in particular (i.e. cranial neural crest), as (...) primary factors for establishing beak size and shape. But these results were limited in their ability to explain fully the morphogenetic bases of patterned outgrowth. So in a quest to identify novel genes whose expression correlated with differences in beak anatomy among Darwin's finches, a DNA microarray approach was undertaken using tissues harvested from the Galápagos Islands. The results are striking and point to a protein called calmodulin, which is a mediator of cellular calcium signaling, as a key determinant of beak length.

In The Selfish Gene, Richard Dawkins crystallized the gene's eye view of evolution developed by W.D. Hamilton and others. The book provoked widespread and heated debate. Written in part as a response, The Extended Phenotype gave a deeper clarification of the central concept of the gene as the unit of selection; but it did much more besides. In it, Dawkins extended the gene's eye view to argue that the genes that sit within an organism have an influence that reaches (...) out beyond the visible traits in that body - the phenotype - to the wider environment, which can include other individuals. So, for instance, the genes of the beaver drive it to gather twigs to produce the substantial physical structure of a dam; and the genes of the cuckoo chick produce effects that manipulate the behaviour of the host bird, making it nurture the intruder as one of its own. This notion of the extended phenotype has proved to be highly influential in the way we understand evolution and the natural world. It represents a key scientific contribution to evolutionary biology, and it continues to play an important role in research in the life sciences. The Extended Phenotype is a conceptually deep book that forms important reading for biologists and students. But Dawkins' clear exposition is accessible to all who are prepared to put in a little effort. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think. (shrink)

The main goal of this paper is to investigate whether humans are unique in using tools and artifacts. Non-human animals exhibit some impressive instances of tool and artifact-use. Chimpanzees use sticks to get termites out of a mound, beavers build dams, birds make nests, spiders create webs, bowerbirds make bowers to impress potential mates, etc. There is no doubt that some animals modify and use objects in clever and sophisticated ways. But how does this relate to the way in which (...) humans make and use objects to achieve their goals? To answer this question, this paper first presents a taxonomy of artifacts, identifying four overlapping categories, namely embodied, perceptual, cognitive, and affective artifacts. It then discusses definitions of animal tool-use, arguing that we need a more liberal approach, one that goes beyond the use of tools that are embedded in occurrent perception-action cycles. This paper ends by analysing how instances of animal tool and artifact-use can be classified according to the four identified categories, concluding that some animals use embodied, perceptual, cognitive, and affective artifacts. In this sense, humans are thus not unique in the kinds of tools and artifacts we use. What is unique, however, is our unprecedented flexibility and openness to deeply incorporate a large variety of complex tools and artifacts into our embodied, perceptual, cognitive, and affective systems.

Contemporary theories of civic education frequently appeal to an ideal of mutual respect in the context of ethical, ethical and religious disagreement.

We talk as if there are natural kinds and in particular we quantify over them. We can count the number of elements discovered by Sir Humphrey Davy, or the number of kinds of particle in the standard model. Consequently, it looks at first sight at least, that natural kinds are entities of a sort. In the light of this we may ask certain questions: is the apparent existence of natural kinds real or an illusion? And if real, what sort of (...) entity are natural kinds? Are they sui generis? Or can they be identified with or reduced to some other kind of entity? In this essay I shall look at possible reasons for asserting that either kinds are no sort of entity, or, if they are entities, their existence is equivalent to some fact not involving kinds. Richard Boyd seems to take the view that the apparent existence of natural kinds is an illusion. (shrink)

The eagle has always been recognized as one of Pindar's most potent and characteristic images. Horace borrowed it to construct the first four stanzas of his Pindaric imitation in Carm. 4.4, and he presents both himself and Pindar as soaring birds: see Carm. 4.2.25 and 2.20, where the swan outflies Daedalus and Icarus in a way that the imitators of Pindar cannot hope to do. It is standard doctrine that Pindar often describes himself as an eagle, and that Bacchylides ‘imitates’ (...) the notion in his fifth ode , p.l). (shrink)

My purpose is to account for some oddities in what Kant did and did not say about "moral worth," and for another in what commentators tell us about his intent.

I distinguish between two things Kant might have had in mind under the heading of moral worth. They come readily to mind when one both takes account of what he (...) actually said about it and notices a fact which he did not seem to notice: namely, that dutiful action- action which, whatever its motive, fulfills a duty-can be over- determined, and determined in particular by both respect for duty and some consortium of inclinations and prudenc.

Bird songs often display musical acoustic features such as tonal pitch selection, rhythmicity, and melodic contouring. We investigated higher-order musical temporal structure in bird song using an experimental method called “music scrambling” with human subjects. Recorded songs from a phylogenetically diverse group of 20 avian taxa were split into constituent elements and recombined in original and random order. Human subjects were asked to evaluate which version sounded more “musical” on a per-species basis. Species identity and stimulus treatment were (...) concealed from subjects, and stimulus presentation order was randomized within and between taxa. Two recordings of human music were included as a control for attentiveness. Participants varied in their assessments of individual species musicality, but overall they were significantly more likely to rate bird songs with original temporal sequence as more musical than those with randomized temporal sequence. We discuss alternative hypotheses for the origins of avian musicality, including honest signaling, perceptual bias, and arbitrary aesthetic coevolution. (shrink)

he theory o f natural selection provides a mechanistic, causal account of how living things came to look as if they had been designed for a purpose. So overwhelming is the appearance of purposeful design that, even in this Darwinian era when we know "better," we still find it difficult, indeed boringly pedantic, to refrain from teleological language when discussing adaptation. Birds' wings are obviously "for" flying, spider webs are for catching insects, chlorophyll molecules are for photosynthesis, DNA molecules are (...) for... What are DNA molecules for? The question takes us aback. In my case it touches off an almost audible alarm siren in the mind. If we accept the view of life that I wish to espouse, it is the forbidden question. DNA is not "for" anything. If we wish to speak teleologically, all adaptations are for the preservation of DNA; DNA itself just is. Following Williams, I have advocated this view at length, and I do not want to repeat myself here. Instead I shall try to clear up an important misunderstanding of the view, a misunderstanding that has constituted an unnecessary barrier to its acceptance. (shrink)

A dispositional property is a tendency, or potency, to manifest some characteristic behaviour in some appropriate context. The mainstream view in the twentieth century was that such properties are to be explained in terms of more fundamental non-dispositional properties, together with the laws of nature. In the last few decades, however, a rival view has become popular, according to which some properties are essentially dispositional in nature, and the laws of nature are to be explained in terms of these fundamental (...) dispositions. The supposed ability of fundamental dispositions to ground natural laws is one of the most attractive features of the dispositional essentialist position. In this paper, however, I cast doubt on the ability of dispositional essences to ground the laws of nature. In particular I argue that the dispositional essentialist position is not able to coherently respond—sympathetically or otherwise—to Cartwright's challenge that there are no true general laws of nature.

A common response to Richard Dawkins' assault on religious belief has been that he is attacking a straw man. The beliefs of religious believers, so the protest goes, are not as crude and simplistic as the ones which he attributes to them.

Card-carrying rationalists like Dawkins…invariably come up with vulgar caricatures of religious faith that would make a first-year theology student wince. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.3 (2001) 425-444 [Access article in PDF] The Passions and Animal Language, 1540-1700 R. W. Serjeantson "Do not think, kind and benevolent readers, that I am proposing a useless subject to you by choosing to discuss the language [loquela] of beasts. For this is nothing other than philosophy, which investigates the natures of animals." 1 The Italian medical professor Hieronymus Fabricius ab Aquapendente (...) began his 1603 treatise On the language of beasts with this captatio benevolentiae with good cause. For early modern natural philosophers almost universally insisted that only humans were capable of language and speech. In this they followed, sometimes explicitly, their ancient authorities. "Man," Aristotle had said in the Politics, "is the only animal that has the gift of speech." "Men," wrote Cicero in the De inventione, "most excel the beasts in this, that they can speak." 2 They were sentiments echoed throughout the sixteenth and seventeenth centuries. "There is no true language among beastes," said Sir Kenelm Digby. "Language" (loquela), concurred G. J. Vossius, "is unique to man." And according to John Ray in The Wisdom of God (1691), speech was "a quality so peculiar to Man, that no Beast could ever attain to it." 3Language was a subject of absorbing interest to numerous early modern philosophers. They investigated its origin, its production, its signification, and its use. But behind almost all of these investigations lay one of the most profound suppositions in early modern anthropology: the uniqueness of the human [End Page 425] capacity for language, and the brutishness of the brute beasts. Harsh judgments were passed on those who thought that animals might be able to speak. Lawyers held that belief in animal language was sufficient evidence of idiocy. According to Kenelm Digby it was only vanity, ignorance, and a specious desire for reputation that had led some authors to argue that animals used "compleate languages as Men haue to discourse with one another in." And the seventeenth-century English writer on the passions, Edward Reynolds, thought that only "melancholy men" believed "that Elephants and Birds, and other Creatures have a language whereby they discourse with one another." 4Yet despite this pervasive assumption that humans spoke and animals did not, the question of animal language kept arising in early modern culture. Readers met speaking animals in beast fablesand on Lucianic voyages. There was a popular belief in early modern England that "in the olde tymes" animals could speak. 5 Theodore Zwinger, Claude Duret, and G. J. Vossius all recorded many accounts of human communication with birds, with the ancient claim that Apollonius of Tyana could understand birdsong being particularly notorious. 6 In the Old Testament Balaam's ass asks his owner what he has done to deserve being beaten. 7 And St. Basil had even suggested that before the Fall Adam and Eve had been able to talk to the animals as well as to name them--a suggestion that both Thomas Browne and Joseph Glanvill gave short shrift. 8 But my purpose in this paper is not to follow speaking animals through early modern fables, popular beliefs, or even Biblical commentary. Instead, I propose to explore the serious investigations of zoosemiotics and animal communication that were undertaken by numerous philosophers in the sixteenth and seventeenth centuries. 9For then as now, the question of animal language, broadly interpreted, was a serious one for the sciences. It was a question that was addressed across a wide range of disciplines, from logic to natural history. As such it was an important component of the many discussions of the nature of animal reason--discussions that provided a means for skeptical moral philosophers to humble human pretensions [End Page 426] to rationality and wisdom. 10 Natural philosophers, too, undertook detailed inquiries into the question of animal expression, exploring issues of articulacy, anatomy, and function. Almost all early modern authors agreed that animals could not speak and did not possess language in the same way that humans did. But this still left a great deal of scope for considering the extent... (shrink)

All of us get opinions from other people. And not just a few. We acquire opinions from others extensively and do so from early childhood through virtually every day of the rest our lives. Sometimes we rely on others for relatively inconsequential information. Is it raining outside? Did the Yankees win today? But we also depend on others for important or even life preserving information. Where is the nearest hospital? Do people drive on the left or the right here? We (...) acquire opinions from family and close acquaintances but also from strangers. We get directions from and heed the warnings of individuals we’ve never met, and likewise read books and articles and listen to television and radio reports authored by individuals we don’t know personally. Moreover, we undertake inquiries in groups in which the group relies on the conclusions of the individuals making up the group. In some of these collective efforts everyone knows one another, for example, a set of neighbors taking a census of birds in the neighborhood. But others, such as the effort to understand gravity, are not so nearly self-contained. Indeed, many of the most impressive human intellectual accomplishments are the collective products of individuals far removed from another in location (and sometimes even over time) who rely on each other’s conclusions without feeling the need to re-confirm them.

This infamous book has enjoyed a lively underground reputation since its first publication in 1970. Richard Meltzer (a.k.a. R. Meltzer) took his training as a young philosopher and applied it with unalloyed enthusiasm to the lyrics, sound, and culture of rock and roll. Never before had anyone noticed the relationship between the philosophy of Heidegger and a tune by Little Anthony and the Imperials, heard the cries of agony in the Shangri Las' “Remember (Walkin' in the Sand)”, or transcribed (...) every "papa-ooma-mow-mow" in the Trashmen's “Surfin' Bird.”From Dionne Warwick to Plato, Jim Morrison to Bert Brecht, Conway Twitty to Miguel de Unamuno, Meltzer subverts high and low culture in his search for meaning, emotion, and codes in popular music. At once an earnest investigation and a crypto put-on, the book can be read for its nuggets of information and insights or for its humor. Here with Greil Marcus's new introduction, yet another generation of readers can be outraged and inspired. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Princess and the Philosopher: Letters of Elisabeth of the Palatine to Rene DescartesRichard A. WatsonAndrea Nye. The Princess and the Philosopher: Letters of Elisabeth of the Palatine to Rene Descartes. Lanham, MD: Rowman & Littlefield, 1999. Pp. xiii + 187. Cloth, $57.95. Paper, $18.95.Princess Elisabeth was an acute, persistent critic of Descartes's philosophy. Because he liked her and she was a princess, Descartes did not dismiss her (...) criticisms as he did those of Gassendi and Hobbes. How can an immaterial mind interact with a material body? How can God determine all our actions and yet give us free will? Elisabeth was dissatisfied with Descartes's answer that an all-powerful God can do anything even if we cannot understand how.Andrea Nye analyzes the correspondence between Elisabeth and Descartes to support the thesis that Elisabeth developed and defended a worldly philosophy of life in opposition to the unworldly rules Descartes offered for living a tranquil and happy life. Descartes said she should focus on the separation of the mind from the body to avoid disturbing the intellect with sensory matters. Think positively about such nice things as birds and flowers and not of bad things that happen to one. Descartes told Elisabeth that "there are no events so dreadful, nor so absolutely bad in the judgments of people, that a person of spirit cannot look on them with a bias that makes them appear favorable" (48). If we do our best to find out the right course of action and act accordingly, then even if the results are bad, we have no reason for remorse or recrimination, but can be happy that we have done the best we can. Descartes even says that a person who follows his rules can view everything that happens to him, even the worst, as though these events were taking place in a theatre, for in the end they do not impinge upon the ultimate happiness of one's immortal soul.Elisabeth, earnestly. sardonically, and sometimes with annoyance responds that this is perhaps possible for a single man of independent means with few civil and personal relationships, but for someone engaged in family affairs, royal politics, and social interaction with other human beings, Descartes's philosophy of life is both impossible and wrong. One never knows what is best; even if one did know, it is difficult to carry it out; and finally, if the results are bad, then one is after all responsible. One would be inhuman to deny fault, monstrous to deny moral responsibility. Above all, Elisabeth says, one should not view one's own life as theatre. One must be responsible for oneself and others.Nye casts this as a difference between Descartes's abstract and Elisabeth's particularist approaches to life, but also as a contrast between those who can live a disengaged life and those who cannot. Some of the amusement in Nye's perceptive discussions comes from her showing how Descartes's passions often run away with him, and how Elisabeth gently turns his own rules back onto him. [End Page 277]Nye's analyses of the correspondence are excellent, but she makes some mistakes about the lives of Descartes and Elisabeth. Nye explains Descartes's coolness by his having suffered from a "motherless infancy" (129), even speaking of "the mother's milk denied him as a child" and calling him an "orphan" (156), which he was not. His mother died thirteen months after his birth, but he had a wet nurse. Descartes may never have tasted his own mother's milk, but he was never deprived of nursing. Children were often sent to live with wet nurses for as long as four years, although Descartes is traditionally said to have been raised by his grandmother. In any event, such psychoanalyzing is off the mark.Nye also says that Descartes was asked by Queen Christina to write a ballet. She cites the wrong ballet and attributes a verse from the right ballet incorrectly, but beyond that, there is no evidence either that Descartes wrote verses for a ballet or that Christina asked him to.Then Nye speaks of Descartes's daughter Francine...

Cetaceans show high cognitive abilities and strong social bonds. Their primary sensory modality to communicate and sense the environment is acoustics. Research on their echolocation and social vocalizations typically uses visual and tactile systems adapted from research on primates or birds. Such research would benefit from a purely acoustic communication system to better match their natural capabilities. We argue that a full duplex system, in which signals can flow in both directions simultaneously is essential for communication research. We designed and (...) implemented a full duplex system to acoustically interact with cetaceans in the wild, featuring digital echo-suppression. We pilot tested the system in Arctic Norway and achieved an echo suppression of 18 dB. We discuss the limiting factors and how to improve the echo suppression further. The system enabled vocal interaction with the underwater acoustic scene by allowing experimenters to listen while producing sounds. We describe our motivations, then present our pilot deployment and give examples of initial explorative attempts to vocally interact with wild orcas and humpback whales. (shrink)

Despite the challenges associated with virtually mediated communication, remote collaboration is a defining characteristic of online multiplayer gaming communities. Inspired by the teamwork exhibited by players in first-person shooter games, this study investigated the verbal and behavioral coordination of four-player teams playing a cooperative online video game. The game, Desert Herding, involved teams consisting of three ground players and one drone operator tasked to locate, corral, and contain evasive robot agents scattered across a large desert environment. Ground players could move (...) throughout the environment, while the drone operator’s role was akin to that of a “spectator” with a bird’s-eye view, with access to veridical information of the locations of teammates and the to-be-corralled agents. Categorical recurrence quantification analysis was used to measure the communication dynamics of teams as they completed the task. Demands on coordination were manipulated by varying the ground players’ ability to observe the environment with the use of game “fog.” Results show that catRQA was sensitive to changes to task visibility, with reductions in task visibility reorganizing how participants conversed during the game to maintain team situation awareness. The results are discussed in the context of future work that can address how team coordination can be augmented with the inclusion of artificial agents, as synthetic teammates. (shrink)

This paper offers an interpretation of Anscombe’s account of animal versus human intention, and of her notorious claim that the expression of intention is purely conventional.

If temperature does not vary from one generation from to the next but its value is crucial for the development of particular phenotypic characteristics, a long-term change in its value may trigger major evolutionary changes of the organism.

However, the language of intentions rests on different (...) evidence and assumptions from causal language and the languages are not interchangeable.

Solar Resources takes stock of the resource - sunlight - on which any plan for solar heat conversion technologies must be based. It describes the evolution of theoretical models, algorithms, and equipment for measuring, analyzing, and predicting the quantity and composition of solar radiation, and it reviews and directs readers to insolation databases and other references that have been compiled since 1975. Following an overview of solar energy research by the editor, Raymond J. Bahm presents a comprehensive guide to available (...) insolation databases and other information resources in the United States. Charles M. Randall and Richard Bird discuss the theoretical models and algorithms used to characterize the transference of solar radiation through the earth's atmosphere. Their chapter also addresses the important question of the accuracy of the data sets produced by the various modeling methods and algorithms. The National Weather Service monitoring network and other major monitoring networks in the United States are discussed by Kirby Hanson and Thomas Stoffel. And Eugene Zerlaut covers the instrumentation used to measure total solar irradiance and spectral solar irradiance; he describes types of equipment, their manufacturers, procedures for calibration, and the accuracy of the data produced. Richard Bird and Carol Riordan explain the nature of spectral solar irradiance at the earth's surface, and John Jensenius describes the NWS Operational Solar Insolation Forecast System, which predicts the daily total global-horizontal insolation for two days. In the concluding chapter, Claude Robbins summarizes daylighting models and resources, and details methods for converting insolation date to illuminance data.

The proof theory of many-valued systems has not been investigated to an extent comparable to the work done on axiomatizatbility of many-valued logics. Proof theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. One particular method for systematically obtaining calculi for all finite-valued logics was invented independently by several researchers, with slight variations in design and presentation. The main aim of this report is to develop the proof theory of finite-valued first order (...) logics in a general way, and to present some of the more important results in this area. In Systems covered are the resolution calculus, sequent calculus, tableaux, and natural deduction. This report is actually a template, from which all results can be specialized to particular logics.

Logic has pride of place in mathematics and its 20th century offshoot, computer science. Modern symbolic logic was developed, in part, as a way to provide a formal framework for mathematics: Frege, Peano, Whitehead and Russell, as well as Hilbert developed systems of logic to formalize mathematics. These systems were meant to serve either as themselves foundational, or at least as formal analogs of mathematical reasoning amenable to mathematical study, e.g., in Hilbert’s consistency program. Similar efforts continue, but have been (...) expanded by the development of sophisticated methods to study the properties of such systems using proof and model theory. In parallel with this evolution of logical formalisms as tools for articulating mathematical theories (broadly speaking), much progress has been made in the quest for a mechanization of logical inference and the investigation of its theoretical limits, culminating recently in the development of new foundational frameworks for mathematics with sophisticated computer-assisted proof systems. In addition, logical formalisms developed by logicians in mathematical and philosophical contexts have proved immensely useful in describing theories and systems of interest to computer scientists, and to some degree, vice versa. Three examples of the influence of logic in computer science are automated reasoning, computer verification, and type systems for programming languages. (shrink)

Methods available for the axiomatization of arbitrary finite-valued logics can be applied to obtain sound and complete intelim rules for all truth-functional connectives of classical logic including the Sheffer stroke and Peirce’s arrow.

Omitting these rules results in systems for intuitionistic versions of (...) the connectives in question. (shrink)
