In order to formulate hypotheses about the evolutionary underpinnings that preceded the first glimmerings of language, mother-infant gestural and vocal interactions are compared in chimpanzees and humans and used to model those of early hominins. These data, along with paleoanthropological evidence, suggest that prelinguistic vocal substrates for protolanguage that had prosodic features similar to contemporary motherese evolved as the trend for enlarging brains in late australopithecines/early Homo progressively increased the difficulty of parturition, thus causing a selective shift toward females that (...) gave birth to relatively undeveloped neonates. It is hypothesized that hominin mothers adopted new foraging strategies that entailed maternal silencing, reassuring, and controlling of the behaviors of physically removed infants (i.e., that shared human babies' inability to cling to their mothers' bodies). As mothers increasingly used prosodic and gestural markings to encourage juveniles to behave and to follow, the meanings of certain utterances (words) became conventionalized. This hypothesis is based on the premises that hominin mothers that attended vigilantly to infants were strongly selected for, and that such mothers had genetically based potentials for consciously modifying vocalizations and gestures to control infants, both of which receive support from the literature. Key Words: bipedalism; brain size; chimpanzees; foraging; gestures; hominins; infant riding; motherese; prosody; protolanguage. (shrink)

Unlike chimpanzees, human infants engage in persistent adult-directed (AD) crying, and human mothers produce a special form of infant-directed vocalization, known as motherese. These complementary behaviors are hypothesized to have evolved initially in our hominin ancestors in conjunction with the evolution of bipedalism, and to represent prelinguistic substrates that paved the way for the eventual emergence of protolanguage.

My responses to the observations and criticisms of 26 commentaries focus on the coregulated and affective nature of initial mother/infant interactions, the relationship between motherese and emergent linguistic skills and its implication for hominin evolution, the plausibility of the “putting the baby down” hypothesis, and details about specific neurological substrates that may have formed the basis for the evolution of prelinguistic behaviors and, eventually, protolanguage.

‘Molinism’, in contemporary usage, is the name for a theory about the workings of divine providence. Its defenders include some of the most prominent contemporary Protestant and Catholic philosophical theologians.¹ Molinism is often said to be the only way to steer a middle..

The authors discuss the political, moral, cultural, and legal aspects of the United States' response to the attacks of September 11.

Many people share the intuition that by turning to works of literature something can be learned about the world. One way to explain the epistemic access to the world that fictional literature provides is by comparing it to thought experiments. Both? thought experiments and works of fiction? might be seen as imaginative exercises which help to find out what would or could happen if certain conditions were met. This comparison of fictional literature with thought experiments provides the point of departure (...) for the contributions in our volume. It contributes to the discussion of an approach that has quite recently entered the field of the philosophy of literature. (shrink)

Property dualism is enjoying a slight resurgence in popularity, these days; substance dualism, not so much. But it is not as easy as one might think to be a property dualist and a substance materialist. The reasons for being a property dualist support the idea that some phenomenal properties (or qualia) are as fundamental as the most basic physical properties; but what material objects could be the bearers of the qualia? If even some qualia require an adverbial construal (if they (...) are modifications of the thing that is conscious because of them, not properties of something else to which the subject of consciousness is related), then the property dualist can be driven to speculative forms of materialism none of which, at this point, looks more likely to be true than the more modest versions of emergent dualism defended by contemporary substance dualists.

Developments in the sequencing of whole genomes and in simultaneously surveying many thousands of transcription and translation products of specific cells have ushered in a conceptual revolution in genetics that rationally introduces top-down, holistic analyses. This emphasized the futility of attempts to reduce genes to structurally discrete entities along the genome, and the need to return to Johannsen's definition of a gene as 'something' that refers to an invariant entity of inheritance and development. We may view genes either as generic (...) terms for units of inheritance whose referents are pragmatic ad hoc and context-dependent, or as (epistemologically) representing entities of cell functions. It is cellular functions that determine the structural referents along the DNA. Structures that happened to secure specific functions that were essential for or conducive to the survival of cells were selected for. With natural selection being the etiological background of genes as functions, genes obtain again their theoretical role as intervening variables, abstractive variables that purely 'summarize' characters. The importance of DNA sequences is that of all possible phenotypes these are the most basic ones from which we can read off the genotype directly. (shrink)

In this classic analysis of travel and sightseeing, author Dean MacCannell brings social scientific understandings to bear on tourism in the postindustrial age, during which the middle class has acquired leisure time for international travel. In _The Tourist_—now with a new introduction framing it as part of a broader contemporary social and cultural analysis—the author examines notions of authenticity, high and low culture, and the construction of social reality around tourism.

Selective scientific realists disagree on which theoretical posits should be regarded as essential to the empirical success of a scientific theory. A satisfactory account of essentialness will show that the (approximate) truth of the selected posits adequately explains the success of the theory. Therefore, (a) the essential elements must be discernible prospectively; (b) there cannot be a priori criteria regarding which type of posit is essential; and (c) the overall success of a theory, or ‘cluster’ of propositions, not only individual (...) derivations, should be explicable. Given these desiderata, I propose a “unification criterion” for identifying essential elements. (shrink)

Let us say that an extended object is “composed wholly of simples” just in case it is an aggregate of absolutely unextended parts spread throughout an extended region—that is, just in case there is a set S such that: every member is a point-sized part of the object, and for every x, x is part of the object if and only if it has a part in common with some member of S. Could a truly extended substance be composed entirely (...) of unextended parts? Reflection upon the fact that it must be at least possible for extended objects to touch one another suggests that the answer to this question is: No. (shrink)

Der deutsch-griechische Philosophiehistoriker und politische Denker Panajotis Kondylis lebte von 1943 bis 1998. Er hat ein umfangreiches Werk hinterlassen, in das die einzelnen Aufsätze des Bandes einführen. "Die Urteile von Kondylis zeichnen sich aus durch Nüchternheit und einen Ernüchterungseffekt, durch Klarheit der Argumente und ihre Begründung, durch Unbestechlichkeit einer offenen Parteinahme jenseits aller modischen Schwankungen und Zumutungen. Seine wissenssoziologisch aufregende These, dass sich Identitäten ändern können oder sukzessive auswechselbar werden, während die reale Existenz einer Person sich durchhält, dieser erfahrungsgesättigte Satz (...) beruht auf seiner ganz persönlichen Leistung, nämlich seine eigene Existenz nie aufgegeben oder gewechselt oder gar verraten zu haben".

Shows that the very same asymmetries that arise for intentionally also arise from deciding, desiring, in favor of, opposed to, and advocating. It seems that the phenomenon is not due to anything about the concept of intentional action in particular. Rather, the effects observed for the concept of intentional action should be regarded as just one manifestation of the pervasive impact of moral judgment.

‘Ifs’ come washed or unwashed. The washed ifs are embedded in precise theories: the constantly strict implication of deductive inference, the variably strict implication of ‘nearness’ conditionals, and statements of conditional probability. By a nearness conditional I mean the common part of Stalnaker's and D. Lewis's theory of counterfactual conditionals, which depends on a notion that possible worlds are more or less near to each other, as a measure of their over-all similarity to each other.

According to philosophical naturalism, the main anti-naturalism in philosophy derives from Kant and depends on transcendental arguments, which are invalid or polemically toothless. Many of naturalism's characteristic features follow from this repudiation of Kantian method. Anti-naturalists should be aware that the rationale for naturalism depends on this attack on their own position. There remains for philosophy a distinctively philosophical role that depends on the indexical element in our thought, the role of elaborating a scientific worldview.

There are two approaches to the phenomenon of community in contemporary social ontology. The first is an attempt to account for community in terms of joint action or cooperation. Margaret Gilbert thus believes that by elucidating the nature of joint action we can come to understand more complex forms of collectivity such as communities. The second approach, put forth by John Searle, is to conceive of community as an institutional entity, that is, as a status collectively assigned to a set (...) of people that unites them as a social group. In this paper, I show why both these approaches fail to provide a convincing account of community. A more promising approach can be found in medieval philosophy, namely, in Thomas Aquinas. His account of community builds on the Aristotelian notion of friendship and, so I argue, yields a better understanding of the relation between community, cooperation, and institutions. (shrink)

In two eye-tracking studies we investigated the influence of Mandarin numeral classifiers – a grammatical category in the language – on online overt attention. Mandarin speakers were presented with simple sentences through headphones while their eye-movements to objects presented on a computer screen were monitored. The crucial question is what participants look at while listening to a pre-specified target noun. If classifier categories influence Mandarin speakers' general conceptual processing, then on hearing the target noun they should look at objects that (...) are members of the same classifier category – even when the classifier is not explicitly present. The data show that when participants heard a classifier they shifted overt attention significantly more to classifiermatch objects than to distractor objects, but when the classifier was not explicitly presented in speech, overt attention to classifier-match objects and distractor objects did not differ. This suggests that although classifier distinctions do influence eye-gaze behavior, they do so only during linguistic processing of that distinction and not in moment-to-moment general conceptual processing.
