Division of labor and its associated phenomena have been viewed as prime examples of group-level adaptations. However, the adaptations are the result of the process of evolution by natural selection and thus require that groups of insects once existed and competed for reproduction, some of which had a heritable division of labor while others did not. We present models, based on those of Kauffman (1984) that demonstrate how division of labor may occur spontaneously among groups of mutually tolerant individuals. We (...) propose that division of labor itself is not a product of natural selection but instead is a "typical" outcome of self organization. (shrink)

It is strange to write for the pages of this journal a statement which will not come under the eye of its founding editor, Sheldon Sacks. For nearly five years everything that appeared in Critical Inquiry—articles, critical responses, editorial comments—was a matter of painstaking and passionate concern to Shelly Sacks. With a flow of questions and suggestions and a talent for unabashed cajolery, he generated articles and rejoinders to those articles. He worked tirelessly in editorial consultation and correspondence with contributors, (...) especially young writers, helping them to discover the best way of giving form to their ideas. Among the essays submitted to this journal he searched eagerly, even anxiously, for those which seemed, in his words, "right for C.I." What was right for C. I. was never, for Shelly Sacks, a cut-and-dried choice. In his own intellectual life, in his teaching and writing, he delighted in arguing important general questions: theories of representation in the arts, points of possible intersection between linguistic science and literary criticism, the interplay of social forces and cultural expressions. Not surprisingly, in reconnoitering for Critical Inquiry, he found special satisfaction in identifying writers who shared his passion for reexamining fundamental topics in the intellectual disciplines. If such writers made their case forcefully, so much the better: in choosing an essay for publication he assessed its capacity to stimulate interesting counterargument. At no time, however, did Shelly Sacks confuse his own beliefs with the nature of intellectual discourse. As an editor he was hospitable to writers whose premises he questioned and whose conclusions he deplored. Nor did Shelly attempt to achieve a spurious catholicity by following a quiet quota system designed to give each major line of interpretation—deconstructionist, Marxist, psychoanalytic, what have you—an occasional airing in Critical Inquiry. For Shelly each article stood on its own ground: if its author dealt responsibly and freshly with an interesting problem, that was enough. And, along with his commitment to theoretical inquiry, he responded warmly to the personal, the offbeat, the idiosyncratic. He regarded the feature Artists on Art, for example, as a central element in our design. As an editor Sheldon Sacks was above all a shaper. He labored to find and suggest connections in the phenomena of intellectual life. Even the construction of a table of contents for a typical Critical Inquiry issue became for him an opportunity to influence the reader's experience of what we offered. The eminence of an author or the allure of a title were put to one side as Shelly sought to orchestrate, through placement, a kind of intellectual counterpoint from one essay to another. Unheard melodies, doubtless, for many of us, but for Shelly real and sustaining. In this valedictory note we have spoken of Sheldon Sacks' editorial accomplishment—in our friendly view, a very distinguished one—rather than of the personal qualities which made working alongside him an exhilarating experience. We should report, however, that for more than half the life of this journal Shelly was ill and knew that the time available to him was likely to be relatively brief. Faced with this diminishing perspective, he did not—indeed it is more accurate to say he could not—moderate his involvement with the life of this journal. At his death, as at the launching of this enterprise, he held to the high ambition that Critical Inquiry encourage comeliness, vigor, and continuity in the discourse of our time. The appropriate "critical response" to this great loss is that Sheldon Sacks’ editorial colleagues, and our publisher, the University of Chicago Press, pledge whatever talents and energies we possess to the continuing life of the journal he imagined and brought into being.

Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

The social organization of insect colonies has fascinated biologists and natural historians for centuries. Aristotle wrote in History of Animals about a division of labor among workers within the hive that is based on age. He observed that the field bees foraging for nectar and pollen have less “hair” on their bodies than the hive bees that care for young larvae and tend the nest. He concluded that the more pubescent hive bees must be older. We now know that, in (...) fact, the field bees are older and have less hair because the hairs break off as the bees age. The phenomenon of age related changes in behavior, age-polyethism, is now well documented for many social insects (Oster and Wilson 1978).Evidence of the ecological success of social insects is inescapable. Virtually everywhere you look you see them or the results of their activities. (shrink)

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex func- tioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/ (...) Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.

Mitchell et al. contend that there is no need to posit a contribution based on the formation of associative links to human learning. In order to sustain this argument, they have ignored evidence which is difficult to explain with propositional accounts; and they have mischaracterised the evidence they do cite by neglecting features of these experiments that contradict a propositional account.

Much has been said about Confucius’ negative formulation of the Golden Rule. Most discussions center on explaining why this formulation, while negative, does not differ at all in intention from the positive formulation. It is my view that such attempts may have the effect of blurring the essential point behind the specifically negative formulation, a point which I hope to elucidate in this essay. It is my first contention that such a negative formulation is consonant with other basic implicit Confucian (...) attitudes such as modesty and the belief in the inherent goodness of human nature. My second contention is that this negative formulation has the intent and/or effect of promoting growth and, more importantly, preventing moral harm. My broader thesis is that the negative version of the Golden Rule does differ significantly from the positive version and that the difference that exists might well have been intended by Confucius to highlight the nature of his most basic moral principle.

The discovery of a letter in the Niels Bohr archives written by Bohr to a Danish schoolteacher in which he reveals his early knowledge of the Daodejing led the present author on a search to unveil the influence of the philosophy of Yin-Yang on Bohr's famed complementarity principle in Western physics. This paper recounts interviews with his son, Hans, who recalls Bohr reading a translated copy of Laozi, as well as Hanna Rosental, close friend and associate who also confirms the (...) influence of ancient Chinese philosophy on this major figure in Western physics. As with Bohr’s dual perspective approach to the wave-particle, in which describing matter as either wave or particle is not considered inherently contradictory, this article likewise argues that Eastern and Western perspectives about philosophy, reality and life in general need not antagonize one another as is the case in Hegelian dialecticism. Through developing a globally accessible, harmonized system of Eastern and Western thought, this article suggests that individuals can more easily overcome limitations arising from cultural singularity in conventional philosophical approaches and, in turn, achieve a greater degree of social harmony and depth of philosophical understanding, all in the same stroke.

The common understanding of Chuang-Tzu as one of the earliest deconstructionists is only half true. This article sets out to challenge conventional characterizations of Chuang-Tzu by adding the important caveat that not only is he a philosophical deconstructionist but that his writings also reveal a non-relativistic, transcendental basis to understanding. The road to such understanding, as argued by this author, can be found in Chuang-Tzu’s emphasis on the illusory or dream-like nature of the self and, by extension, the subject-object dichotomy (...) inherent in all forms of conceptualization and descriptive language. These two obstacles to true understanding - the self and literal, linguistic expressions - are overcome in the Chuang-Tzu by implementing metaphorical and poetic language, such as the Kun-Peng myth, the swamp pheasant parable, the introduction of physically deformed interlocutors, various dream analogies, and so forth. By employing such literary devices in a comprehensible and non-mystical manner, this article concludes that Chuang-Tzu successfully communicates his essential wisdom by guiding the reader to a higher state of spiritual awareness, a state in which one transcends the self, language, conceptual paradoxes, and even the idea of transcendence itself. Consequently, through the following explication of Chuang-Tzu’s complementary emphasis on both preventing mental rigidity and promoting spiritual transcendence, this article seeks to earn Chuang-Tzu the reputation of a deconstructionist with a difference.

If we peruse the Chuang Tzu (Zhuangzi) and the Nietzschean corpus, we will find numerous examples of evaluative statements. And yet, both Chuang Tzu and Nietzsche are well known for their critique of conventional value distinctions. Time and again they argue that our conventional value distinctions are invalid and sometimes even harmful. Are these two philosophers justified in making what appear to be self-negating claims? This essay offers a line of argument to justify their employment of evaluative language while at (...) the same time disclaiming its validity. My essential argument is that there are two levels of consciousness in both of these philosophers and that evaluative language is transcended at one of these levels but still possesses limited validity at the other. I assume, I believe correctly, that the purpose of philosophy for both philosophers is self-transformation. Given this functional direction of philosophizing, I divide the types of statements I will analyze into three standpoints: (1) “evaluative standpoint,” or statements which I take to be primarily evaluative in nature. “Class i” refers to the evaluative standpoint which is the standpoint not yet transcended and to be transcended; (2) “transevaluative standpoint”, or statements which I take to be primarily transevaluative in nature. “Class ii” refers to the transevaluative standpoint which is the standpoint to be achieved; (3) “transevaluative resultant values,” or statements which are primarily statements of the resultant value which are the product of a value free standpoint. “Class iii” refers to the resultant concrete values which are the product of following the transevaluative standpoint. My analyses lead to the conclusion that evaluative language is employed in its appropriate level of consciousness and transcended in the other level. In short, I propose that Chuang Tzu and Nietzsche can have their cake, and eat it, too. (shrink)

This article takes one of the richest historical debates, that of Hsun-Tzu and Mencius, as the contextual starting-point for the elaboration of human goodness. In support of Mencius, this article develops additional metaphysical and bio-social-evolutionary grounds, both of which parallel each other. The metaphysical analysis suggests that, in the spirit of Spinoza, an entity’s nature must necessarily include the drive toward its preservation. Likewise, the multi-faceted bio-social-evolutionary argument locates the fundamental telos of humanity in the preservation of social ties and (...) species preservation, leading to a life-affirming philosophy and bio-psychological deduction of human emotions based on the primary emotion of love.

This paper advances the thesis that the raw version of the butterfly dream story in the Chuang-tzu is logically untenable and should thus be replaced by a logically coherent altered version. First, it sets out the positive meaning of the butterfly dream. Second, it examines the raw version of the butterfly dream so as to point up its inherent illogicality. Third, it sets out a modified version of the butterfly dream and demonstrates its superior logicality. Fourth, it shows how conventional (...) interpretations of the butterfly dream story—the ‘confusion hypothesis’ and the ‘external endless transformation’ hypothesis—arise from the raw version and identifies basic weaknesses in the conventional interpretation options. Fifth and last, it returns to an in-depth consideration of the interpretation which arises from a re-ordering of the butterfly dream story fragments. The raw version of the story makes little sense, which is why, I propose, it has lacked a satisfactory interpretation. This thesis stands on three presuppositions. The butterfly dream story is an analogy of the enlightenment experience. The enlightenment experience, or the experience of illumination, is the phenomenological correlate of the central objective of the Chuang-tzu, that of self-transformation. And the enlightenment experience is not only the phenomenological correlate, but the essential pre-condition for self-transformation. By refashioning our (mis)interpretations of the butterfly dream story, we can more fully appreciate its transformative message. (shrink)

ABSTRACT Theories of the influence of technology on modern Western society have failed to take into account the important role played by a widespread pattern of sociotechnical practice. The pattern in question involves the interplay of technology, rights, and numbers. This paper argues that in the context of an ever more potent technological arsenal and an ever increasing number of individuals who have access to its elements and believe themselves entitled to use them in maximalist ways, adherence to the traditional (...) notion of individual human rights is anachronistic and increasingly problematic for the quality of life in contemporary society. To combat this situation, I criticise the idea of human rights as timelessly valid and offer a contextualised account of these constructs, one able to take on board the implications of their maximalist exercise in a populous technological society. I conclude by illustrating the struggles being waged over the adaptation of human rights to techno‐demographic reality in two areas of contemporary Western society: urban planning and medicine.

This article draws on two Mencian illustrations of human goodness: the example of the child in the well and the metaphor of the continually deforested mountain. By reconstructing Mencius’ two novel ideas within the framework of a phenomenological thought-experiment, this article’s purpose is to explain the validity of this uncommon approach to ethics, an approach which recognizes that subjective participation is necessary to achieve any ethical understanding. It is through this active phenomenological introspection that the individual grasps the goodness of (...) human nature, whilst simultaneously coming to realize one’s own degree of closeness (or estrangement) to this universal nature, depending on the success of the thought experiment. Despite the apparent logical circularity of reformulating Mencius in such fashion, this article further maintains that no theoretical premises need be taken up prior to reenacting the Mencian thought-experiment. On the contrary, this article explains that knowledge of human nature manifests itself in the very moment of the proposed epistemic act. (shrink)

We provide conceptual and empirical support for the core tenet in pragmatic theory that speakers make their communicative intention about the pragmatic meaning of their utterances recognizable to hearers. First, we attribute skepticism about this tenet to conceptualizing communicative intentions as private cognitive states that hearers cannot reliably discern. We show it is more parsimonious to conceptualize communicative intention as arising from communally shared knowledge of discursive means to ends that is the basis for pragmatic reasoning about utterance meaning by (...) speaker and hearer alike. Second, we address skepticism based on experiments interpreted as finding an egocentric bias where people regard communicative intentions as more obvious to others than they are. We report two original experiments we carried out that found that participants as third party observers and as communicators routinely engaged in pragmatic reasoning about the meaning of utterances in context that took others’ perspectives into account.

This commentary questions the proposed resemblance between the auditory mechanisms of localization and those of the sensory registration of speech sounds. Comparative evidence, which would show that the neurophysiology of localization is adequate to the task of categorizing consonants, does not exist. In addition, Sussman et al. do not offer sensory or perceptual evidence to confirm the presence in humans of processes promoting phoneme categorization that are analogous to the neurophysiology of localization. Furthermore, the computational simulation of the linear model (...) of second formant variation is not a plausible sensory mechanism for perceiving speech sounds. (shrink)
