The strong predominance of right-handedness appears to be a uniquely human characteristic, whereas the left-cerebral dominance for vocalization occurs in many species, including frogs, birds, and mammals. Right-handedness may have arisen because of an association between manual gestures and vocalization in the evolution of language. I argue that language evolved from manual gestures, gradually incorporating vocal elements. The transition may be traced through changes in the function of Broca's area. Its homologue in monkeys has nothing to do with vocal (...) control, but contains the so-called “mirror neurons,” the code for both the production of manual reaching movements and the perception of the same movements performed by others. This system is bilateral in monkeys, but predominantly left-hemispheric in humans, and in humans is involved with vocalization as well as manual actions. There is evidence that Broca's area is enlarged on the left side in Homo habilis, suggesting that a link between gesture and vocalization may go back at least two million years, although other evidence suggests that speech may not have become fully autonomous until Homo sapiens appeared some 170,000 years ago, or perhaps even later. The removal of manual gesture as a necessary component of language may explain the rapid advance of technology, allowing late migrations of Homo sapiens from Africa to replace all other hominids in other parts of the world, including the Neanderthals in Europe and Homo erectus in Asia. Nevertheless, the long association of vocalization with manual gesture left us a legacy of right-handedness. Key Words: cerebral dominance; gestures; handedness; hominids; language evolution; primates; speech; vocalization. (shrink)

Why do minds exist? How did mud and stone develop into beings that can experience longing, regret, love, and compassion-beings that are aware of their own experience? Until recently, science offered few answers to these existential questions. Journey of the Mind is the first book to offer a unified account of the mind that explains how consciousness, language, the Self, and civilization emerged incrementally out of chaos. The journey begins three billion years ago with the emergence of the simplest possible (...) mind, a nanoscopic archeon, then ascends through amoebas, worms, frogs, birds, monkeys, and AI, examining successively smarter ways of thinking. The authors explain the mathematical principles generating conscious experience and show how these principles led cities and democratic nations to develop new forms of consciousness-the self-aware "superminds." Journey of the Mind concludes by contemplating a higher stage of consciousness already emerging-and the ultimate fate of all minds in the universe. (shrink)

Hurford argues that propositions of the form PREDICATE(x) represent conceptual structures that predate language and that can be explicated in terms of neural structure. I disagree, arguing that such predicates are descriptions of limited aspects of brain function, not available as representations in the brain to be exploited in the frog or monkey brain and turned into language in the human.

The Chacoan road system is an understudied aspect of a very unique culture in New Mexico. The extensive roads present important evidence to the social structure of the Chaco people. A few theories have been presented about the reason for the roads, such as economic, administrative and religion. This paper argues that the roads were used for military purposes, because the roads provided quick access to all satellite townships in the region.

Some have thought that the plausibility of teleosemantics requires that it yield a determinate answer to the question of what the semantic “content” is of the “representation” triggered in the optic nerve of a frog that spots a fly. An outsize literature has resulted in which, unfortunately, a number of serious confusions and omissions that concern the way teleosemantics would have to work have appeared and been passed on uncorrected leaving a distorted and simplistic picture of the teleosemantic position. I (...) will speak to a half dozen of the worst of these misunderstandings and then say just a word about the frog question itself. (shrink)

It seems to be a truism that whenever we do something - and so, given the omnipresence of trying (Hornsby 1980), whenever we try to do something - we want to do that thing more than we want to do anything else we can do (Davidson 1970). However, according to Frog, when we have will power we are able to try not to do something that we ‘really want to do’. In context the idea is clearly meant to be that (...) what we really want to do and what we most want to do are one and the same. But how is this meant to be so much as possible? It seems to require that our desire not to do what we most want to do is both our strongest desire and not our strongest desire. And that is a blatant contradiction. This is the so-called ‘paradox of self-control’ (Mele 1987). The aim of our paper is to explain how to make sense of the story of Frog and Toad. (shrink)

How do frogs represent their prey? This question has been the focus of many debates among proponents of naturalistic theories of content, especially among proponents of teleosemantics. This is because alternative versions of the teleosemantic approach have different implications for the content of frog representations, and it is still controversial which of these content ascriptions (if any) is the most adequate. Theorists often appeal to intuitions here, but this is a dubious strategy. In this paper, I suggest an alternative, (...) empirical test for theories of content. I propose that we should examine whether a theory generates content ascriptions that fit with our best scientific explanations of animal behavior. I then focus on the most prominent version of teleosemantics, Ruth Millikan’s consumer-oriented approach, and argue that it fails the empirical test in the frog case, since it yields a content ascription that (i) does not include properties that should be included (namely, being small, dark and moving ) and (ii) includes a property that should not be included (namely, being frog food ). This is an important result in itself, but it also demonstrates by way of example how progress can be made in the complex debate about theories of content. (shrink)

The article analyzes the neural and functional grounding of language skills as well as their emergence in hominid evolution, hypothesizing stages leading from abilities known to exist in monkeys and apes and presumed to exist in our hominid ancestors right through to modern spoken and signed languages. The starting point is the observation that both premotor area F5 in monkeys and Broca's area in humans contain a “mirror system” active for both execution and observation of manual actions, and that F5 (...) and Broca's area are homologous brain regions. This grounded the mirror system hypothesis of Rizzolatti and Arbib (1998) which offers the mirror system for grasping as a key neural “missing link” between the abilities of our nonhuman ancestors of 20 million years ago and modern human language, with manual gestures rather than a system for vocal communication providing the initial seed for this evolutionary process. The present article, however, goes “beyond the mirror” to offer hypotheses on evolutionary changes within and outside the mirror systems which may have occurred to equip Homo sapiens with a language-ready brain. Crucial to the early stages of this progression is the mirror system for grasping and its extension to permit imitation. Imitation is seen as evolving via a so-called simple system such as that found in chimpanzees (which allows imitation of complex “object-oriented” sequences but only as the result of extensive practice) to a so-called complex system found in humans (which allows rapid imitation even of complex sequences, under appropriate conditions) which supports pantomime. This is hypothesized to have provided the substrate for the development of protosign, a combinatorially open repertoire of manual gestures, which then provides the scaffolding for the emergence of protospeech (which thus owes little to nonhuman vocalizations), with protosign and protospeech then developing in an expanding spiral. It is argued that these stages involve biological evolution of both brain and body. By contrast, it is argued that the progression from protosign and protospeech to languages with full-blown syntax and compositional semantics was a historical phenomenon in the development of Homo sapiens, involving few if any further biological changes. Key Words: gestures; hominids; language evolution; mirror system; neurolinguistics; primates; protolanguage; sign language; speech; vocalization. (shrink)

The philanthropist and philosopher Strachan Donnelley (1942--2008) devoted his life to studying the complex relationship between humans and nature. Founder and first president of the Center for Humans and Nature, Donnelley was a pioneer in the exploration and promotion of the idea that human beings individually and collectively have moral and civic responsibilities to natural ecosystems. In this wide-ranging volume, Donnelley traces the connections between influential figures such as Aldo Leopold and Charles Darwin, as well as lesser-known but original thinkers (...) that he met during the course of a full life -- ministers at his church, friends with whom he fished, and colleagues who shared his passion for research and writing. He grounds his work in classic philosophers such as Descartes, Spinoza, and Whitehead and reinterprets their writings about the natural world to develop a conservation-centered philosophy, which he dubs "democratic ecological citizenship." Edited by his daughter, Ceara Donnelley, and Bruce Jennings, Frog Pond Philosophy illuminates the dominant strands of Donnelley's intellectual identity as a philosopher, naturalist, agitator, and spiritualist. Despite his often grim depiction of the current state of the environment, Donnelly never surrenders his faith in humanity's ability to meet its ethical obligations to conserve, respect, and nurture the complexity and diversity of the natural world. His vivid and personal essays, rooted in everyday experiences, offer a distinctive perspective on questions of urgent contemporary importance. (shrink)

Recent work in judgment and decision-making has shown that a good’s price can have irrational effects on people’s preferences. People tend to prefer goods that cost more money and assume that such expensive goods will be more effective, even in cases where the price of the good is itself arbitrary. Although much work has documented the existence of these pricing effects, unfortunately little work has addressed where these price effects come from in the first place. Here we use a comparative (...) approach to distinguish between different accounts of this bias and to explore the origins of these effects. Specifically, we test whether brown capuchin monkeys (Cebus apella) are also susceptible to pricing effects within the context of an experimentally trained token economy. Using a capuchin population previously trained in a token market, we explored whether monkeys used price as an indicator of value across four experiments. Although monkeys demonstrated an understanding of which goods had which prices (consistently shifting preferences to cheaper goods when prices were increased), we observed no evidence that such price information affected their valuation of different kinds of goods. These results suggest that human price effects may involve more sophisticated human-unique cognitive capacities, such as an understanding of market forces and signaling. (shrink)

We develop a formal semantic analysis of the alarm calls used by Campbell’s monkeys in the Tai forest and on Tiwai island —two sites that differ in the main predators that the monkeys are exposed to. Building on data discussed in Ouattara et al. :e7808, 2009a; PNAS 106: 22026–22031, 2009b and Arnold et al., we argue that on both sites alarm calls include the roots krak and hok, which can optionally be affixed with -oo, a kind of attenuating suffix; in (...) addition, sentences can start with boom boom, which indicates that the context is not one of predation. In line with Arnold et al., we show that the meaning of the roots is not quite the same in Tai and on Tiwai: krak often functions as a leopard alarm call in Tai, but as a general alarm call on Tiwai. We develop models based on a compositional semantics in which concatenation is interpreted as conjunction, roots have lexical meanings, -oo is an attenuating suffix, and an all-purpose alarm parameter is raised with each individual call. The first model accounts for the difference between Tai and Tiwai by way of different lexical entries for krak. The second model gives the same underspecified entry to krak in both locations, but it makes use of a competition mechanism akin to scalar implicatures. In Tai, strengthening yields a meaning equivalent to non-aerial dangerous predator and turns out to single out leopards. On Tiwai, strengthening yields a nearly contradictory meaning due to the absence of ground predators, and only the unstrengthened meaning is used. (shrink)

Aristophanes’ Frogs was first performed at the Lenaea festival of 405 in competition with Plato's Cleophon and Phrynichus’ Muses. This paper argues that Frogs contains a series of agonistic jokes against Phrynichus, most of which have gone unnoticed because he shares his name with a tragic poet and a politician; Aristophanes plays with the ambiguity of the name Phrynichus to mock his Lenaean rival by comparing him unfavourably with his namesakes. Aristophanes ultimately claims that his comedy is superior (...) to that of Phrynichus because he is more successful than his rival in appropriating and redeploying other comedians’ material.

The parodos of the Frogs is one of the most controversial passages in Aristophanes. Was it intended to parody the Eleusinian Mystery procession—or some other ritual? A writer wishing to discuss any part of the parodos must first outline his position with regard to this basic problem. I shall therefore as simply and briefly as possible state my own view and the reasons for it before dealing with the specific question posed by the title of the article.

Research with nonhuman primates is essential to medical progress and will still be necessary for the foreseeable future. Almost all research scientists agree that animal research is critical to understanding basic biology, discovering new treatments for human (and animal) diseases, and maximizing the safety of new medicines while minimizing their harm to humans. All but two of the Nobel prizes in medicine awarded over the last one hundred years have depended on animal research, and the list of modern medicines, vaccines, (...) and other treatments, as well as basic science discoveries, is so extensive that it could not be adequately covered in even a huge volume. Increases in average life span in the last century are the result of improved public health measures, and many diseases may be related to lifestyle choices. But animal research has contributed to understanding these factors and to the development of vaccines and lifesaving treatments. The philosophical debate regarding the benefits and moral costs of animal research has also filled many volumes by ethicists and philosophers. The major arguments against the use of animals in medical research have been explicitly refuted by a few brave scientists, as well as implicitly by the vast majority of the working biomedical science community. My contribution to this discussion is to provide a personal perspective on my decision if, when, and how to use monkeys in research experiments on Parkinson disease. As a physician researcher, I have been working for many years to understand and cure Parkinson disease. (shrink)

Aeschylus has just defeated Euripides in the verse-weighing round of their contest. In 1407–10 he issues a final challenge, that with two lines he could outweigh Euripides' whole household. But as it stands the challenge is incomplete; to finish it we need something like ‘and my poetry would easily appear the heavier’. Perhaps Aeschylus is interrupted by the next speaker— or, it has been suggested, by a thunderclap heralding the arrival of Pluto.

Although at first glance it may seem an unlikely alliance, frogs and cyberfrogs certainly benefit from an unusual friendship that connects the virtual world of dissection simulation and the physical realm of nonhuman animal advocacy.This paper focuses on the symbiotic relationship of dissection simulation designers and animal advocates. Dissection simulation manufacturers benefit from this relationship through the purchasing and promotion of their products by animal advocacy organizations, and also they benefit from policy changes that encourage the use of dissection (...) simulations as alternatives to dissection. Reciprocally,animal advocacy organizations benefit by saving animal lives, gaining a new tool for convincing teachers to stop dissecting, and demonstrating that they are a pro-technology movement. The knowledges and values embedded in cyberfrogs make them both boundary objects and cyborgs. (shrink)

In this essay we discuss a class of apparently metaphorical idioms, exemplified by “fine as frog's hair,” that do not afford any obvious interpretation, and appear to have originated, at least in part, in language play. We review recent trends in both play theory and metaphor theory, and show that a playful approach to language is often an important element in the use and understanding of metaphors (and idioms generally), even when metaphors can be readily interpreted by means of a (...) vehicle-to-topic mapping. Based on this evidence we call for a more deliberate inclusion of language play in metaphor theory and analysis. (shrink)

In Japan, yaen kōen or "wild monkey parks" are popular visitor attractions that show free-ranging monkey troops to the paying public. Unlike zoos, which display nonhuman animals through confinement, monkey parks control the movements of the monkeys through provisioning. The parks project an image of themselves as "natural zoos," claiming to practice a more authentic form of displaying animals-in-the-wild than that practiced by the zoo. This article critically evaluates the monkey park's claim by examining park management (...) of the monkeys. The article shows the monkey park's claim to display wild monkeys to be questionable because of the way that provisioning changes monkey behavior. Against the background of human encroachment onto the forest habitat of the monkey, the long-term effect of provisioning is to sedentarize nomadic monkey animals and to turn the wild monkey park into a megazoo.

The Judeo-Christian creation myth has a lot to answer for even in our supposedly secular age. In and after the European Enlightenment, the deity who had made heaven and earth became the prototype of impersonal forces—notably Universal Reason, Progress, and History—then believed to be at work in the world. These apparent secularizations of the Word of God, each of which failed in its own way, were expressions of a collective fear of the unintelligible, that is, of the very idea that (...) the world might just be without reason or purpose. What follows is an attempt to explore the forms and origins of this fear, which perhaps remains unresolved in our culture to this day. It begins outside the Judeo-Christian tradition with the world view implied, on one interpretation, in a famous haiku by the seventeenth-century Japanese poet Bashō. The essay ends by suggesting that secular society will achieve a completely honest accommodation with the world only when it comes to terms with the reality of the creation, namely.. (shrink)

The chapter discusses the following quotation from Charles Peirce: "One of these days, perhaps, there will come a writer of opinions less humdrum than those of Dr. (Alfred Russel) Wallace, and less in awe of the learned and official world...who will argue, like a new Bernard Mandeville, that man is but a degenerate monkey, with a paranoic talent for self-satisfaction, no matter what scrapes he may get himself into, calling them 'civilization,' and who, in place of the unerring instincts (...) of other races, has an unhappy faculty for occupying himself with words and abstractions, and for going wrong in a hundred ways before he is driven, willy-nilly, into the right one.

Virtue ethics has generated a great deal of excitement among ethicists largely because it is seen as an alternative to the traditional theories – utilitarianism and Kantian ethics – which have come under considerable scrutiny and criticism in the past 30 years. Rather than give up the enterprise of doing moral theory altogether, as some have suggested, others have opted to develop an alternative that would hopefully avoid the shortcomings of both utilitarianism and Kantian ethics. Several writers, such as Jorge (...) Garcia and Michael Slote, have tried to develop this alternative of virtue ethics, or at least sketch out ways such a theory could be developed. (shrink)

This research examines how and why reactions to other consumers’ unethical behavior differ among consumers and vary in different situations. Drawing on construal level theory, the authors propose that the relationship between other consumers’ unethical behavior and focal consumers’ unethical behavior is moderated by focal consumers’ construal level, and self-expressiveness mediates this moderating effect. Specifically, consumers at higher construal levels tend to view their behavior as more self-expressive and are thus less likely to imitate other consumers’ unethical behavior. Study 1 (...) indicates that focal consumers who have a chronic tendency to construe information at high levels are less likely to replicate other consumers’ unethical behavior than those who have a chronic tendency to construe information at low levels. Studies 2, 3a and 3b show that when primed with higher-level construals, consumers are less likely to follow other consumers’ unethical behavior than when primed with lower-level construals. The mediating effect of self-expressiveness was tested and supported in Study 1 and Study 3b. These findings help to better understand consumers’ reactions to other consumers’ unethical behavior.

Due to the NP-hard nature, the permutation flowshop scheduling problem is a fundamental issue for Industry 4.0, especially under higher productivity, efficiency, and self-managing systems. This paper proposes an improved genetic-shuffled frog-leaping algorithm to solve the permutation flowshop scheduling problem. In the proposed IGSFLA, the optimal initial frog in the initialized group is generated according to the heuristic optimal-insert method with fitness constrain. The crossover mechanism is applied to both the subgroup and the global group to avoid the local optimal (...) solutions and accelerate the evolution. To evolve the frogs with the same optimal fitness more outstanding, the disturbance mechanism is applied to obtain the optimal frog of the whole group at the initialization step and the optimal frog of the subgroup at the searching step. The mathematical model of PFSSP is established with the minimum production cycle as the objective function, the fitness of frog is given, and the IGSFLA-based PFSSP is proposed. Experimental results have been given and analyzed, showing that IGSFLA not only provides the optimal scheduling performance but also converges effectively. (shrink)
