The use of cochlear implants, especially for prelingually deafened children, has aroused heated debate. Members and proponents of Deaf culture vigorously oppose implants both as a seriously invasive treatment of dubious efficacy and as a threat to Deaf culture. Some find these arguments persuasive; others do not. And in this context arise questions about the extent to which individuals with disabilities may decline treatments to ameliorate disabling conditions. When they do so, to what extent may they call upon society to (...) provide supportive services and accommodations? (shrink)

People often signal their membership in groups through their clothes, hairstyle, posture, and dialect. Most existing evolutionary models argue that markers label group members so individuals can preferentially interact with those in their group. Here we ask why people mark ethnic differences when interethnic interaction is routine, necessary, and peaceful. We asked research participants from three ethnic groups in southwestern Madagascar to sort photos of unfamiliar people by ethnicity, and by with whom they would prefer or not prefer to cooperate, (...) in a wage labor vignette. Results indicate that southwestern Malagasy reliably send and detect ethnic signals; they signal less in the marketplace, a primary site of interethnic coordination and cooperation; and they do not prefer co-ethnics as cooperation partners in novel circumstances. Results from a cultural knowledge survey and calculations of cultural FST suggest that these ethnic groups have relatively little cultural differentiation. We concur with Moya and Boyd that ethnicity is unlikely to be a singular social phenomenon. The current functions of ethnic divisions and marking may be different from those at the moment of ethnogenesis. Group identities may persist without group conflict or differentiation. (shrink)

A fact of life for farmers, hunter-gatherers, and fishermen in the rural parts of the world are that crops fail, wild resources become scarce, and winds discourage fishing. In this article we approach subsistence risk from the perspective of "coexistence thinking," the simultaneous application of natural and supernatural causal models to explain subsistence success and failure. In southwestern Madagascar, the ecological world is characterized by extreme variability and unpredictability, and the cosmological world is characterized by anxiety about supernatural dangers. Ecological (...) and cosmological causes seem to point to different risk minimizing strategies: to avoid losses from drought, flood, or heavy winds, one should diversify activities and be flexible; but to avoid losses caused by disrespected spirits one should narrow one's range of behaviors to follow the code of taboos and offerings. We address this paradox by investigating whether southwestern Malagasy understand natural and supernatural causes as occupying separate, contradictory explanatory systems (target dependence), whether they make no categorical distinction between natural and supernatural forces and combine them within a single explanatory system (synthetic thinking), or whether they have separate natural and supernatural categories of causes that are integrated into one explanatory system so that supernatural forces drive natural forces (integrative thinking). Results from three field studies suggest that (a) informants explain why crops, prey, and market activities succeed or fail with reference to natural causal forces like rainfall and pests, (b) they explain why individual persons experience success or failure primarily with supernatural factors like God and ancestors, and (c) they understand supernatural forces as driving natural forces, so that ecology and cosmology represent distinct sets of causes within a single explanatory framework. We expect that future cross-cultural analyses may find that this form of "integrative thinking" is common in unpredictable environments and is a cognitive strategy that accompanies economic diversification.

recruits or the area of its influence, which has been attained by Modern Socialism, and at the same time been so little understood and so misunderstood, not only by the hostile and the indifferent, but by the friendly, and even by the great mass of its adherents themselves. This unfortunate and highly dangerous state of things is due partly to the fact that the human relationships which this movement – if anything so chaotic can be called a movement – aims (...) to transform, involve no special class or classes, but literally all mankind; partly to the fact that these relationships are infinitely more varied and complex in their nature than those with which any special reform has ever been called upon to deal; and partly to the fact that the great moulding forces of society, the channels of information and enlightenment, are well-nigh exclusively under the control of those whose immediate pecuniary interests are antagonistic to the bottom claim of Socialism that labor should be put in possession of its own.

This paper begins with the hypothesis that Mikea, participants in a mixed foraging–fishing–farming–herding economy of southwestern Madagascar, may attempt to reduce interannual variance in food supply caused by unpredictable rainfall by following a simple rule-of-thumb: Practice an even mix of activities that covary positively with rainfall and activities that covary negatively with rainfall. Results from a historical matrix participatory exercise confirm that Mikea perceive that foraging and farming outcomes covary positively or negatively with rainfall. This paper further considers whether Mikea (...) learn about covariation through personal observation and memory recall (individual learning) or through socially transmitted ethnotheory (social learning). Dual inheritance theory models by Boyd and Richerson (1988) predict that individual learning is more effective in spatially and temporally variable environments such as the Mikea Forest. In contrast, the psychological literature suggests that individuals judge covariation poorly when memory of past events is required, unless they share a socially learned theory that a covariation should exist (Nisbett and Ross 1980). Results suggest that Mikea rely heavily on shared ethnotheory when judging covariation, but individuals continually strive to improve their judgment through individual observation. (shrink)

us, I go at once to the heart of the subject, taking my stand on these propositions: That the right to cooperate is as unquestionable as the right to compete; that the right to compete involves the right to refrain from competition; that co operation is often a method of competition, and that competition is always, in the larger view, a method of co operation; that each is a legitimate, orderly, non invasive exercise of the individual will under the social (...) law of equal liberty; and that any man or institution attempting to prohibit or restrict either, by legislative enactment or by any form of invasive force, is, in so far as such man or institution may fairly be judged by such attempt, an enemy of liberty, an enemy of progress, an enemy of society, and an enemy of the human race.

Human behavioral ecology (HBE) began as an attempt to explain human economic, reproductive, and social behavior using neodarwinian theory in concert with theory from ecology and economics, and ethnographic methods. HBE has addressed subsistence decision-making, cooperation, life history trade-offs, parental investment, mate choice, and marriage strategies among hunter-gatherers, herders, peasants, and wage earners in rural and urban settings throughout the world. Despite our rich insights into human behavior, HBE has very rarely been used as a tool to help the people (...) with whom we work. This article introduces a special issue of Human Nature which explores the application of HBE to significant world issues through the design and critique of public policy and international development projects. The articles by Tucker, Shenk, Leonetti et al., and Neil were presented at the 104th annual meeting of the American Anthropological Association (AAA) in Washington, D.C., in December 2005, in the first organized session of the nascent Evolutionary Anthropology Section (EAS). We conclude this introduction by summarizing some theoretical challenges to applying HBE, and ways in which evolutionary anthropologists can contribute to solving tough world issues. (shrink)

Read Jus, 17 June 1887): The voluntary taxation proposal really means the dissolution of the State into its constituent atoms, and leaving them to recombine in some way or no way, just as it may happen. There would be nothing to prevent the existence of five or six "States" in England, and members of all these "States" might be living in the same house! The proposal is, it appears to me, the outcome of an idea in the minds of those (...) who propound it that the State is, or ought to be, founded on contract, just as a joint stock company is. ... The explanation of the whole matter, I believe, is that ... the State is a social organism, evolved as every other organism is evolved, and not requiring any more than other organisms to be based upon a contract ...

Century has requested me to answer for his readers. I comply; but, to be frank, I find it a difficult task. If the editor or one of his contributors had only suggested a reason why I should be anything other than an Anarchist, I am sure I should have no difficulty in disputing the argument. And does not this very fact, after all, furnish in itself the best of all reasons why I should be an Anarchist – namely, the impossibility (...) of discovering any good reason for being anything else? To show the invalidity of the claims of State Socialism, Nationalism, Communism, Single taxism, the prevailing capitalism, and all the numerous forms of Archism existing or proposed, is at the same blow to show the validity of the claims of Anarchism. Archism once denied, only Anarchism can be affirmed. That is a matter of logic. (shrink)

Governments and non-govermental organizations (NGOs) that plan projects to conserve the environment and alleviate poverty often attempt to modify rural livelihoods by halting activities they judge to be destructive or inefficient and encouraging alternatives. Project planners typically do so without understanding how rural people themselves judge the value of their activities. When the alternatives planners recommend do not replace the value of banned activities, alternatives are unlikely to be adopted, and local people will refuse to participate. Human behavioral ecology and (...) behavioral economics may provide useful tools for generating and evaluating hypotheses for how people value economic activities in their portfolios and potential alternatives. This is demonstrated with a case example from southwestern Madagascar, where plans to create a Mikea Forest National Park began with the elimination of slash-and-burn maize agriculture and the encouragement to plant labor-intensive manioc instead. Future park plans could restrict access to wild tuber patches, hunting small game, and fishing. The value of these activities is considered using observational data informed by optimal foraging theory, and experimental data describing people’s time preference and covariation perception. Analyses suggest that manioc is not a suitable replacement for maize for many Mikea because the two crops differ in terms of labor requirements, delay-to-reward, and covariation with rainfall. Park planners should promote wild tuber foraging and stewardship of tuber patches and the anthropogenic landscapes in which they are found. To conserve small game, planners must provide alternative sources of protein and cash. Little effort should be spent protecting lemurs, as they are rarely eaten and never sold. (shrink)
