Recent studies of scientific interaction based on agent-based models suggest that a crucial factor conducive to efficient inquiry is what Zollman has dubbed ‘transient diversity’. It signifies a process in which a community engages in parallel exploration of rivaling theories lasting sufficiently long for the community to identify the best theory and to converge on it. But what exactly generates transient diversity? And is transient diversity a decisive factor when it comes to the efficiency of inquiry? In this paper we (...) examine the impact of different conditions on the efficiency of inquiry, as well as the relation between diversity and efficiency. This includes certain diversity-generating mechanisms previously proposed in the literature, as well as some factors that have so far been neglected. This study is obtained via an argumentation-based ABM. Our results suggest that cautious decision-making does not always have a significant impact on the efficiency of inquiry while different evaluations underlying theory-choice and different social networks do. Moreover, we find a correlation between diversity and a successful performance of agents only under specific conditions, which indicates that transient diversity is sometimes not the primary factor responsible for efficiency. Altogether, when comparing our results to those obtained by structurally different ABMs based on Zollman’s work, the impact of specific factors on efficiency of inquiry, as well as the role of transient diversity in achieving efficiency, appear to be highly dependent on the underlying model.

Much of the time, human beings seem to rely on habits. Habits are learned behaviours directly elicited by context cues, and insensitive to short-term changes in goals: therefore they are sometimes irrational. But even where habitual responses are rational, it can seem as if they are nevertheless not done for reasons. For, on a common understanding of habitual behaviour, agents’ intentions do not play any role in the coming about of such responses. This paper discusses under what conditions we can (...) say that habitual responses are, after all, done for reasons. We show how the idea that habitual behaviour cannot be understood as ‘acting for reasons’ stems from a widely but often implicitly held theoretical framework: the causal theory of action. We then propose an alternative, Anscombean understanding of intentional action, which can account for habitual responses being done for reasons. (shrink)

A well‐known typological observation is the dominance of subject‐initial word orders, SOV and SVO, across the world's languages. Recent findings from gestural language creation paradigms offer possible explanations for the prevalence of SOV. When asked to gesture transitive events with an animate agent and inanimate patient, gesturers tend to produce SOV order, regardless of their native language biases. Interestingly, when the patient is animate, gesturers shift away from SOV to use of other orders, like SVO and OSV. Two competing hypotheses (...) have been proposed for this switch: the noisy channel account (Gibson et al., 2013) and the role conflict account (Hall, Mayberry, & Ferreira, 2013). We set out to distinguish between these two hypotheses, disentangling event reversibility and patient animacy, by looking at gestural sequences for events with two inanimate participants (inanimate‐inanimate, reversible). We replicated the previous findings of a preference for SOV order when describing animate‐inanimate, irreversible events as well as a decrease in the use of SOV when presented with animate‐animate, reversible events. Accompanying the drop in SOV, in a novel condition we observed an increase in the use of SVO and OSV orders when describing events involving two animate entities. In sum, we find that the observed avoidance of SOV order in gestural language creation paradigms when the event includes an animate agent and patient is driven by the animacy of the participants rather than the reversibility of the event. We suggest that findings from gestural creation paradigms are not automatically linkable to spoken language typology. (shrink)

Controversy swept the U.K. in January of 2000 over public disclosure of the fact that a Scottish surgeon named Robert Smith had amputated the limbs of two able-bodied individuals who reportedly suffered from a condition known as apotemnophilia. The patients, both of whom had sought and consented to the surgery, claimed they had desperately desired for years to live as amputees and had been unable, despite considerable efforts, to reconcile themselves psychologically to living with the bodies with which they were (...) born. Both surgeries were successful, and both patients, who had undergone psychiatric evaluation prior to the amputations, subsequently reported having no regrets. In the wake of a wave of sensationalistic stories in the media, the hospital at which the surgeries had been performed, the Falkirk and District Royal Infirmary, banned any future surgeries of the kind. Outraged local politicians promptly announced their intention to pass laws banning the procedure outright. One member of Scottish Parliament declared the surgery obscene and asserted that the whole thing is repugnant and legislation needs to be brought in now to outlaw this. (shrink)

Debates on the moral status of human embryos have been highly and continuously controversial. For many, these controversies have turned into a fruitless scholastical endeavor. However, recent developments and insights in cellular biology have cast further doubt on one of the core points of dissent: the argument from potentiality. In this article we want to show in a nonscholastical way why this argument cannot possibly survive. Getting once more into the intricacies of status debates is a must in our eyes. (...) Not merely intellectual coherence but the standing and self-understanding of current stem cell research might profit from finally taking leave of the argument from potentiality. (shrink)

This case study examines five dimensions of the 2007–2009 financial crisis in the United States: the devastating effects of the financial crisis on the U.S. economy, including unparalleled unemployment, massive declines in gross domestic product, and the prolonged mortgage foreclosure crisis; the multiple causes of the financial crisis and panic, such as the housing and bond bubbles, excessive leverage, lax financial regulation, disgraceful banking practices, and abysmal rating agency performance; the extraordinary efforts of the Federal Reserve, the Federal Reserve Bank (...) of New York, and the Department of the Treasury to stem the financial freefall triggered by the crisis and resuscitate financial institutions, the ethical implications of the unprecedented actions by government institutions to rescue financial institutions and drag the country back from the brink of global financial collapse, and the conduct of the various parties contributing to the financial crisis, such as the shoddy behavior of mortgage brokers, the massive securitization of mortgages into overly complex bonds, the excessive leverage of financial institutions, the disgraceful work of bond rating firms, the abysmal risk management systems employed by financial institutions, and the massive operations of the shadow banking and over-the-counter derivatives markets; and the major provisions of the Dodd–Frank Wall Street Reform and Consumer Protection Act signed into law to in response to the financial crisis and for the purpose of correcting the egregious conduct of major financial institutions.

In part 1 of Enquiry 12, Hume presents a skeptical argument against belief in external existence. The argument involves a perceptual relativity argument that seems to conclude straightaway the double existence of objects and perceptions, where objects cause and resemble perceptions. In Treatise 1.4.2, Hume claimed that the belief in double existence arises from imaginative invention, not reasoning about perceptual relativity. I dissolve this tension by distinguishing the effects of natural instinct and showing that some ofthese effects supplement the Enquiry’s (...) perceptual relativity argument. The Enquiry’s skeptical argument thus reveals the fundamental involvement of natural instinct in any belief in external existence. (shrink)

Even the simplest narratives combine multiple strands of information, integrating different characters and their actions by expressing multiple perspectives of events. We examined the emergence of referential shift devices, which indicate changes among these perspectives, in Nicaraguan Sign Language (NSL). Sign languages, like spoken languages, mark referential shift grammatically with a shift in deictic perspective. In addition, sign languages can mark the shift with a point or a movement of the body to a specified spatial location in the three-dimensional space (...) in front of the signer, capitalizing on the spatial affordances of the manual modality. We asked whether the use of space to mark referential shift emerges early in a new sign language by comparing the first two age cohorts of deaf signers of NSL. Eight first-cohort signers and 10 second-cohort signers watched video vignettes and described them in NSL. Narratives were coded for lexical (use of words) and spatial (use of signing space) devices. Although the cohorts did not differ significantly in the number of perspectives represented, second-cohort signers used referential shift devices to explicitly mark a shift in perspective in more of their narratives. Furthermore, while there was no significant difference between cohorts in the use of non-spatial, lexical devices, there was a difference in spatial devices, with second-cohort signers using them in significantly more of their narratives. This suggests that spatial devices have only recently increased as systematic markers of referential shift. Spatial referential shift devices may have emerged more slowly because they depend on the establishment of fundamental spatial conventions in the language. While the modality of sign languages can ultimately engender the syntactic use of three-dimensional space, we propose that a language must first develop systematic spatial distinctions before harnessing space for grammatical functions.

This interview, conducted over email, is an exchange between Annemarie Mol, a philosopher and Professor of Anthropology of the Body at the University of Amsterdam, and Ada Jaarsma, associate editor of Symposium. While the questions reflect Jaarsma’s interests in Mol’s account of “empirical philosophy” and its import for contemporary Continental philosophy, Mol’s responses raise questions, in turn, about how phrases like “Continental philosophy” betray geographical and canonical presumptions. Reflecting on the import of wonder, of reading, of intervening in philosophy’s (...) set tropes, and of decentring the subject, Mol draws readers into an array of ways to reconsider the cultural repertoires and social realities by which philosophical activities take place.

A comprehensive look at the decline of the United States offers non-ideological remedies on how to overcome national self-doubt, reclaim optimism, and secure a prosperous future for American citizens.

It is commonly thought that w v quine's indeterminacy thesis can be devastatingly undercut by a straightforward survey of the details of one's own linguistic capabilities. However, Because any such survey must depend upon a repudiation of the quinean doctrines used to generate his thesis, Objections based upon introspective evidence remain question begging without a critique of those more central doctrines. Since such a critique would be sufficient in itself to undermine quine's thesis, Objections based upon introspective gleanings must be (...) abandoned as either question begging or superfluous.

In this paper we introduce hypersequent-based frameworks for the modelling of defeasible reasoning by means of logic-based argumentation and the induced entailment relations. These structures are an extension of sequent-based argumentation frameworks, in which arguments and the attack relations among them are expressed not only by Gentzen-style sequents, but by more general expressions, called hypersequents. This generalization allows us to overcome some of the known weaknesses of logical argumentation frameworks and to prove several desirable properties of the entailments that are (...) induced by the extended frameworks. It also allows us to incorporate as the deductive base of our formalism some well-known logics, which lack cut-free sequent calculi, and so are not adequate for standard sequent-based argumentation. We show that hypersequent-based argumentation yields robust defeasible variants of these logics, with many desirable properties. (shrink)

How can constructivism and feminism inform and strengthen one another? The author of this text is a constructivist-feminist hermaphrodite, and so s/he addresses this question in the form of an inner dialogue. Instead of taking sex as a characteristic of individuals, s/he analyzes it as something performed locally in ways that vary from one situation to another. Investigating these performances offers constructivism an interesting theoretical opportunity and a chance to turn away from a sterile anti-epistemological stance. For feminism, a radicalized (...) notion of the construction of sexes opens up new political spaces and strategies. Constructivist texts, moreover, have the potential to "do" both the contingency and the necessity of our forms of life in their very style. (shrink)

We may be at the brink of a Kuhnian paradigm shift when it comes to the categorical classification system of mental disorders. Reviewing more than 30 years of critical literature on the categorical classification of personality disorders, Kueger, Hopwood, Wright, and Markon conclude that the Diagnostic and Statistical Manual of Mental Disorders is "fundamentally broken". Just before, the director of the National Institute of Mental Health declared that the institute will no longer support research that is based on DSM categories.The (...) critique on the categorical system of mental disorders consists of several arguments that are briefly mentioned as they have been...
