The developmental importance to humans of the human-constructed physical environment, including myriad modified natural objects or manufactured objects, is well recognized. The importance of the physical dimension of the constructed niche has also been recognized in nonhuman animals with respect to dwellings (e.g., beavers’ dams, birds’ nests, and bees’ hives), but has not previously been applied to technical traditions, despite the fact that enduring alterations of the physical environment left by social partners are part of the constructed niche that supports (...) the learning of technical skills through the phenomenon of delayed social facilitation. These alterations aid learning over a longer time scale than the actions themselves. Thus, technical skills that result in enduring physical artifacts, which themselves aid learning the skills, should be both more persistent in a population and more widespread than technical skills that do not share this feature. This perspective gives us a new lens through which to understand the origins of technical traditions in nonhuman animals, and by extension, in human ancestors. Understanding the process by which traditional technical skills are acquired in nonhuman species gives us insight into the ways that the combination of social and physical niche construction can support the evolution of technical aspects of culture from modest beginnings.

Domjan et al.'s model of how Pavlovian processes regulate social interaction can be extended to social learning, where an individual learns about the value of events, objects, or actions from information provided by another. The conditioned properties of a particular social partner, following from a history of interactions with that partner, can modulate the efficiency and specificity of social learning.

Applying the framework proposed by Jeffery et al. to nonhuman primates moving in multilayer arboreal and terrestrial environments, we see that these animals must generate a mosaic of many bicoded spaces in order to move efficiently and safely through their habitat. Terrestrial light detection and ranging (LiDAR) technology and three-dimensional modelling of canopy movement may permit testing of Jeffery et al.'s framework in natural environments.

Gender differences in face-based emotion recognition, notably differential use of mimicry, may compromise the extent to which the Simulation of Smiles (SIMS) model can be generalized to populations besides the adult females on which it has been tested. Much work indicates sex differences in face-based emotion recognition, including smile recognition.

The arguments of Stoffregen & Bardy for studying perception based on the global array are intriguing. This theory can be examined in nonhuman species using nonverbal tasks. We examine how monkeys master a skill that incorporates a two-dimensional/three-dimensional interface. We feel this provides excellent support for Stoffregen & Bardy's theory.

We present evidence from neuroimaging and brain lesion studies that emotional contagion may not be a mechanism underlying musical emotions. Our brains distinguish voice from non-voice sounds early in processing, and dedicate more resources to such processing. We argue that super-expressive voice theory currently cannot account for evidence of the dissociation in processing musical emotion and voice prosody.

Book synopsis: Vagueness is currently the subject of vigorous debate in the philosophy of logic and language. Vague terms-such as "tall", "red", "bald", and "tadpole"—have borderline cases ; and they lack well-defined extensions. The phenomenon of vagueness poses a fundamental challenge to classical logic and semantics, which assumes that propositions are either true or false and that extensions are determinate. Another striking problem to which vagueness gives rise is the sorites paradox. If you remove one grain from a heap of (...) sand, surely you must be left with a heap. Yet apply this principle repeatedly as you remove grains one by one, and you end up, absurdly, with a solitary grain that counts as a heap. This anthology collects papers in the field. After an introduction that surveys the field, the essays form four groups, starting with some historically notable pieces. The 1970s saw an explosion of interest in vagueness, and the second group of essays reprints classic papers from this period. The following group of papers represent current work on the logic and semantics of vagueness. The essays in the final group are contributions to the continuing debate about vague objects and vague identity. (shrink)

This classic, with a new introduction by Madeleine L'Engle, is by turns an entrancing mediation on language a piercing commentary on the nature of art and why so much of what we read, hear, and see falls short and a brilliant examination of the fundamental tenets of Christianity. The Mind of the Maker will be relished by those already in love with Dorothy L. Sayers and those who have not yet met her. A mystery writer, a witty and perceptive (...) theologian, culture critic, and playwright, Dorothy Sayers sheds new,unexpected light on a specific set of statements made in the Christian creeds. She examines anew such ideas as the image of God, the Trinity, free will, and evil, and in these pages a wholly revitalized understanding of them emerges. The author finds the key in the parallels between the creation of God and the human creative process. She continually refers to each in a way that illuminates both. (shrink)

"This book is very valuable. Today, there are too many books on the Work that are either deliberately impersonal and as a result are just a re-explaining of basic ideas which are already there in Ouspensky.

This chapter provides the background to the American women philosophers’ works that are introduced and collected in Knowledge, Mind and Reality: An Introduction by Early Twentieth-Century American Women Philosophers. We describe the institutional context which made these works possible and their methodological and theoretical background. We also provide biographies for their authors.

The history of research on the genetics of intelligence is fraught with social bias. During the eugenics era, the hereditary theory of intelligence justified policies that encouraged the proliferation of favored races and coercively stemmed procreation by disfavored ones. In the 1970s, Berkeley psychologist Arthur Jensen argued that black students’ innate cognitive inferiority limited the efficacy of federal education programs. The 1994 controversial bestseller The Bell Curve, by Richard J. Herrnstein and Charles Murray, rehashed the claim that race and class (...) disparities stem from immutable differences in inherited intelligence, which could not be eliminated through social interventions. Today most scientists studying the genetics of intelligence distance themselves from this history of social bias by arguing that their research need not investigate intellectual differences between social groups. Rather, they argue, examining the heritability of intelligence can be socially neutral and may even help to reduce social inequities. I argue, however, that research on the genetics of intelligence cannot be socially neutral. Even if we divorce the heritability of intelligence from a eugenicist mission, measuring intelligence remains useful only as a gage of individuals’ appropriate positions in society. Research into the genetics of intelligence ultimately helps to determine individuals’ inherited capacity for particular social positions, even when researchers aim to modify the effects of inheritance.

We commend Byrne & Russon for their effort to expand and clarify the concept of imitation by addressing the various levels of behavior organization at which it could occur. We are concerned, however, first about the ambiguity with which these levels are defined and second about whether there is any particular need for comparative cognition to keep focusing on imitation as an important intellectual faculty. We recommend stricter definitions of hierarchical behavioral levels that will lend themselves to operational definitions and (...) continued study of how animal subjects organize their goal-directed behavior as opposed to whether it is or is not imitation.

In a number of influential articles published since 1972, Dorothy Grover has developed the prosentential theory of truth. Brought together and published with a new introduction, these essays are even more impressive as a group than they were as single contributions to philosophy and linguistics. Denying that truth has an explanatory role, the prosentential theory does not address traditional truth issues like belief, meaning, and justification. Instead, it focuses on the grammatical role of the truth predicate and asserts that (...) “it is true” is a prosentence, functioning much as a pronoun does. Grover defends the theory by indicating how it can handle notorious paradoxes like the Liar, as well as by analyzing some English truth-usages. The introduction to the volume surveys traditional theories of truth, including correspondence, pragmatic, and coherence theories. It discusses the essays to come and, finally, considers the implications of the prosentential theory for other theories. Despite the fact that the prosentential theory dismisses the “nature of truth” as a red herring, Grover shows that there are important aspects of traditional truth theories that prosentential theorists have the option of endorsing.

There has been a long debate on whether demonstratives are directly referential as Kaplan originally argued, or indirectly referential like a definite description. I propose a new analysis of demonstratives that combines intuitions from both direct and indirect approaches. The demonstrative is analyzed as an indirectly referential expression with a binary maximality operator that takes two arguments, where the second argument can be a deictic pointing, an anaphoric index, or a relative clause. Direct reference is encoded not in the meaning (...) of the demonstrative but in the meaning contributed by the pointing gesture, thus capturing both direct and indirect uses. I further propose that some pronouns in English function as demonstratives, realizing the binary structure and competing with the demonstrative. The main advantages of this proposal include (a) deriving the distribution of pronominal and adnominal demonstratives systematically; (b) capturing the unique interaction that demonstratives have with a pointing gesture; and (c) locating English demonstratives against a larger, cross-linguistic picture.

Benedict Spinoza is feted as the philosopher par excellence of the popular democratic multitude by Antonio Negri and others. But Spinoza himself expresses a marked ambivalence about the multitude in brief asides, and as for his thoughts on what he calls “the rule of multitude,” that is, democracy, these exist only as meager fragments in his unfinished Tractatus Politicus or Political Treatise. This essay addresses the problem of Spinoza’s multitude. First, I reconstruct a vision of power that is found in (...) the Ethics but that tends to be overlooked in the scholarly literature: power is not just sheer efficacy or imposition of will, but rather involves a capacity for being-affected; I call this the conception of power as sensitivity. The second part of my argument shows how, given Spinoza’s emphatic political naturalism, the conception of power as sensitivity can be extended to his political philosophy to shed light on what Spinoza calls potentia multitudinis, or “the power of the multitude”—a term found solely in the Political Treatise and nowhere else in his oeuvre. This juxtaposition reveals significant qualifications to the liberatory potential of the multitude currently claimed in the scholarly literature. (shrink)

The article argues that Marx’s use of the concept of ideology in The German Ideology is incidental to a sustained critique of how those he described as the German ideologists think and reason about society and history and that this critique is not simply of an idealist theory that represents society and history as determined by consciousness but of methods of reasoning that treat concepts, even of those of political economy, as determinants. His view of how consciousness is determined historically (...) by our social being does not envisage some kind of mechanical transfer of class status to class consciousness. Rather, he works with an epistemology that takes the concepts foundational to political economy as expressions or reflections of the social relations of a mode of production. The difference between ideology and science is the difference between treating those concepts as the primitives of theory and treating them as sites for exploring the social relations that are expressed in them. Thus, the historical rather than further undermining claims to knowledge, provides both the conditions under which knowledge is possible and its limitations. (shrink)

The host actin nucleation machinery is subverted by many bacterial pathogens to facilitate their entry, motility, replication, and survival. The majority of research conducted in the past primarily focused on exploitation of a host actin nucleator, the Arp2/3 complex, by bacterial pathogens. Recently, new studies have begun to explore the role of formins, another family of host actin nucleators, in bacterial pathogenesis. This review provides an overview of recent advances in the study of the exploitation of the Arp2/3 complex and (...) formins by bacterial pathogens. Secreted bacterial effector proteins seem to manipulate the regulation of these actin nucleators or functionally mimic them to drive bacterial entry, motility and survival within host cells. An enhanced understanding of how formins are exploited will provide us with greater insight into how a fundamental eurkaryotic cellular process is utilized by bacteria and will also advance our knowledge of host‐pathogen interactions.
