The Upper Palaeolithic Revolution, sometimes called ‘the Creative Explosion’, is seen as the period when the forefathers of modern forager societies emerged. Similarly to the Industrial and Neolithic Revolutions, it represents a short time span when numerous inventions appeared and cultural changes occurred. The inventions were in the domain of technology, that is, shaping of new stone tool forms, longdistance exchange of raw materials, the use of bone, antler and ivory as well as rare minerals for the production of domestic (...) and ritual objects. Spatial analysis of ‘living floors’ indicates the presence of a kitchen area, sleeping grounds, storage facilities (in certain regions) and a discard zone. We can also detect a certain increase in social hierarchy and the presence of shamans. Body decorations indicate the appearance of personal individuality. Several hypotheses were offered as an explanation for the initiation of all these cultural changes often grouped under the term ‘modern behaviour’. It stands to reason that attributing the new successful technologies observed in the Eurasian Upper Palaeolithic to intrinsic social processes and economic innovations by local Middle Palaeolithic populations would need a better archaeological demonstration than that available today. For the time being, the emergence of Modern humans in sub-Saharan Africa, their socio-economic dynamism that caused their expansion through the Nile Valley into the Near East, and their migration along the ‘southern route’ of Asia as far as Australia, is the most plausible scenario though it still leaves much to be desired from future archaeological research.

The Purūravac-cakkiravartti-katai, “The Story of Emperor Purūravas,” is a pre-modern Tamil folk telling of the ancient Urvaśī-Purūravas legend. The classical narrative of King Purūravas of the Lunar Dynasty tells about his love affair with the celestial nymph Urvaśī, their tragic separation, and final reunion. The PCK follows the classical narrative closely, but interposes a long account of other exploits of Purūravas, which do not appear in any of the Sanskrit tellings of the story. In this supplement, which I call “The (...) Tamil Life of Purūravas,” Purūravas faces a tragic chain of unavoidable events, but eventually restores his former status through meditation and devotion. A comparative examination of the two parts of the text, that is, the classical narrative and the Tamil Life, shows that the latter generates an inverted mirror image of the fundamental notions implied in the classical narrative. The outcome of this structure is a shift in the ideological tendencies of the narrative toward a local ethos and popular religious notions. The PCK is thus shown to be a field of cultural negotiations, in which opposing ideologies contend for superiority, and its structure can be regarded as a transformative mechanism applied by local and popular cultural forms to enable appropriation of classical narrative traditions.

The notion of bilattice was introduced by Ginsberg, and further examined by Fitting, as a general framework for many applications. In the present paper we develop proof systems, which correspond to bilattices in an essential way. For this goal we introduce the notion of logical bilattices. We also show how they can be used for efficient inferences from possibly inconsistent data. For this we incorporate certain ideas of Kifer and Lozinskii, which happen to suit well the context of our work. (...) The outcome are paraconsistent logics with a lot of desirable properties.1.

Maximality is a desirable property of paraconsistent logics, motivated by the aspiration to tolerate inconsistencies, but at the same time retain from classical logic as much as possible. In this paper we introduce the strongest possible notion of maximal paraconsistency, and investigate it in the context of logics that are based on deterministic or non-deterministic three-valued matrices. We show that all reasonable paraconsistent logics based on three-valued deterministic matrices are maximal in our strong sense. This applies to practically all three-valued (...) paraconsistent logics that have been considered in the literature, including a large family of logics which were developed by da Costa's school. Then we show that in contrast, paraconsistent logics based on three-valued properly nondeterministic matrices are not maximal, except for a few special cases (which are fully characterized). However, these non-deterministic matrices are useful for representing in a clear and concise way the vast variety of the (deterministic) three-valued maximally paraconsistent matrices. The corresponding weaker notion of maximality, called premaximal paraconsistency, captures the "core" of maximal paraconsistency of all possible paraconsistent determinizations of a non-deterministic matrix, thus representing what is really essential for their maximal paraconsistency.

Many Jewish groups of late antiquity assumed that they were obligated to observe the Divine Law. This book attempts to study the various rationales offered by these groups to explain the authority that the Divine Law had over them. Second Temple groups tended to look towards philosophy or metaphysics to justify the Divine Law's authority. The tannaim, though, formulated legal arguments that obligate Israel to observe the Divine Law. While this turn towards legalism is pan-tannaitic, two distinct legal arguments can (...) be identified in tannaitic literature. These specific arguments about the Divine Law's authority, link to a set of issues regarding the tannaim's conception of Divine Law and of Israel's election. (shrink)

This book tries to answer two key questions. The first is why certain periods are more prone to war than others. The other is why certain wars that involve polar powers end with their territorial expansion whereas other wars end in their contraction or maintaining their territorial status. In conclusion, it is asked whether the polarity of the system affects these two outcomes, and if so, how.

Sometimes, the availability of more evidence for a conclusion provides a reason to believe in its falsity. This counter-intuitive phenomenon is related to the idea of higher-order evidence, which has attracted broad interest in recent epistemological literature. Occasionally, providing more evidence for something weakens the case in its favor, by casting doubt on the probative value of other evidence of the same sort or on the fact-finder’s cognitive performance. We analyze this phenomenon, discuss its rationality, and outline possible application to (...) evidence law and to the law in general. It is suggested, inter alia, that such higher-order evidence may explain how judicial experience-based expertise in fact-finding is possible despite the absence of a feedback mechanism; and that fact-finders’ self-doubt regarding their own competence in making ‘beyond-reasonable doubt’ judgments might be reasonable and should not be ignored.

A new view of the functional role of the left anterior cortex in language use is proposed. The experimental record indicates that most human linguistic abilities are not localized in this region. In particular, most of syntax (long thought to be there) is not located in Broca's area and its vicinity (operculum, insula, and subjacent white matter). This cerebral region, implicated in Broca's aphasia, does have a role in syntactic processing, but a highly specific one: It is the neural home (...) to receptive mechanisms involved in the computation of the relation between transformationally moved phrasal constituents and their extraction sites (in line with the Trace-Deletion Hypothesis). It is also involved in the construction of higher parts of the syntactic tree in speech production. By contrast, basic combinatorial capacities necessary for language processing – for example, structure-building operations, lexical insertion – are not supported by the neural tissue of this cerebral region, nor is lexical or combinatorial semantics. The dense body of empirical evidence supporting this restrictive view comes mainly from several angles on lesion studies of syntax in agrammatic Broca's aphasia. Five empirical arguments are presented: experiments in sentence comprehension, cross-linguistic considerations (where aphasia findings from several language types are pooled and scrutinized comparatively), grammaticality and plausibility judgments, real-time processing of complex sentences, and rehabilitation. Also discussed are recent results from functional neuroimaging and from structured observations on speech production of Broca's aphasics. Syntactic abilities are nonetheless distinct from other cognitive skills and are represented entirely and exclusively in the left cerebral hemisphere. Although more widespread in the left hemisphere than previously thought, they are clearly distinct from other human combinatorial and intellectual abilities. The neurological record (based on functional imaging, split-brain and right-hemisphere-damaged patients, as well as patients suffering from a breakdown of mathematical skills) indicates that language is a distinct, modularly organized neurological entity. Combinatorial aspects of the language faculty reside in the human left cerebral hemisphere, but only the transformational component (or algorithms that implement it in use) is located in and around Broca's area. Key Words: agrammatism; aphasia; Broca's area; cerebral localization; dyscalculia; functional neuroanatomy; grammatical transformation; modularity; neuroimaging; syntax; trace deletion. (shrink)

Paradefinite logics are logics that can be used for handling contradictory or partial information. As such, paradefinite logics should be both paraconsistent and paracomplete. In this paper we consider the simplest semantic framework for introducing paradefinite logics. It consists of the four-valued matrices that expand the minimal matrix which is characteristic for first degree entailments: Dunn–Belnap matrix. We survey and study the expressive power and proof theory of the most important logics that can be developed in this framework.

We introduce a general approach for representing and reasoning with argumentation-based systems. In our framework arguments are represented by Gentzen-style sequents, attacks between arguments are represented by sequent elimination rules, and deductions are made according to Dung-style skeptical or credulous semantics. This framework accommodates different languages and logics in which arguments may be represented, allows for a flexible and simple way of expressing and identifying arguments, supports a variety of attack relations, and is faithful to standard methods of drawing conclusions (...) by argumentation frameworks. Altogether, we show that argumentation theory may benefit from incorporating proof theoretical techniques and that different non-classical formalisms may be used for backing up intended argumentation semantics.

Resisting Contextual Information: You Can't Put a Salient Meaning Down Two experiments support the graded salience hypothesis, which assumes that early processing involves distinct mechanisms-linguistic and contextual-that do not interact but run parallel. While contextual processes make up an integrative, top-down mechanism that benefits from linguistic and extra-linguistic information, the linguistic mechanism is modular. Using Vu et al.'s materials, Experiment 1 shows that the sentential position of a target word is crucial for the operation of the global, predictive mechanism, whose (...) effects, accumulated in prior discourse, mask lexical effects in final, but not in initial position. Experiment 2 shows that even in a sentential position that favors contextual effects, lexical access is not affected: Salient meanings are activated upon encounter of the lexical stimulus, regardless of contextual information to the contrary. Taken together, these findings argue against direct access models, which suggest that context can selectively activate the appropriate meaning, regardless of salience. (shrink)

The neurocentric worldview that identifies the essence of the human being with the material brain has become a central paradigm in current academic discourse. Israeli researchers also seek to understand educational principles and processes via neuroscientific models. On this background, the article uncovers the central role that visual brain images play in the learning-disabilities field in Israel. It examines the place brain images have in the professional imagination of didactic-diagnosticians as well as their influence on the diagnosticians' clinical attitudes. It (...) relies on two theoretical fields: sociology and anthropology of the body and sociology of neuromedical knowledge. The research consists of three methodologies: ethnographic observations, in-depth interviews, and rhetorical analysis of visual and verbal texts. It uncovers the various rhetorical and ideological functions of brain images in the field. It also charts the repertoire of rhetorical devices which are utilized to strengthen the neuroreducionist messages contained in the images. (shrink)

ʻEdut be-Hosef -- Derekh ʻets ha-ḥayim -- Refuʼat ha-nefesh -- ha-Tapuaḥ.

Reasoning with the maximally consistent subsets of the premises is a well-known approach for handling contradictory information. In this paper we consider several variations of this kind of reasoning, for each one we introduce two complementary computational methods that are based on logical argumentation theory. The difference between the two approaches is in their ways of making consequences: one approach is of a declarative nature and is related to Dung-style semantics for abstract argumentation, while the other approach has a more (...) proof-theoretical flavor, extending Gentzen-style sequent calculi. The outcome of this work is a new perspective on reasoning with MCS, which shows a strong link between the latter and argumentation systems, and which can be generalized to some related formalisms. As a by-product of this we obtain soundness and completeness results for the dynamic proof systems with respect to several of Dung’s semantics. In a broader context, we believe that this work helps to better understand and evaluate the role of logic-based instantiations of argumentation frameworks. (shrink)

According to Foucault, the human body is the targeted object of modern power systems. In his genealogical studies, Foucault describes the manner in which these power systems leave an imprint on the body and utilize knowledge of the body as an indirect means of exercising subtle forms of control. In recent years, several researchers have claimed that the status of the body, subsumed as it is by modern power networks, has become a means for conducting a unique political critique in (...) which the human being is viewed as an agent of oppression and freedom. This article takes a fresh look at Foucault’s notions of life and death that underpin the critical understanding the body–power relationship. While this approach recognizes the completeness of subjective structuring processes, it also enables the formulation of new insights regarding the status of the modern individual as the subject of separate and independent modes of speech and action.

Liberal democracy suffers from an internal contradiction stemming from its ideological roots and rending it from within. On the one hand its goal is to generate a system of laws and rules that maximize individual rights and liberties; on the other hand, some of its fundamental assumptions pertaining to the Subject restrict the political and social agent's existential experience to a limited threshold of speech and action. The central assumption of this article is that the main meeting point of the (...) critics of modernity, Apel and Habermas primarily, and the post-structuralists, Foucault and Deleuze, in regard to the Subject, rehabilitates liberal discourse and creates an opening for a political theory that maximizes the freedom of the individual as a structured, anti-essentialist Subject. I will show that the expansion of the concept of the self in the two streams sheds new light on the concepts of political control and liberty, and in this way extends the normative discussion of all aspects of the political agent's status in a modern democracy.

In this paper we provide a proof theoretical investigation of logical argumentation, where arguments are represented by sequents, conflicts between arguments are represented by sequent elimination rules, and deductions are made by dynamic proof systems extending standard sequent calculi. The idea is to imitate argumentative movements in which certain claims are introduced or withdrawn in the presence of counter-claims. This is done by a dynamic evaluation of sequences of sequents, in which the latter are considered ‘derived’ or ‘not derived’ according (...) to the content of the sequence. We show that decisive conclusions of such a process correspond to well-accepted consequences of the underlying argumentation framework. The outcome is therefore a general and modular proof-theoretical approach for paraconsistent and non-monotonic reasoning with argumentation systems. (shrink)

Seventeenth-century optics naturalizes the eye while estranging the mind from objects. A mere screen, on which rests a blurry array of light stains, the eye no longer furnishes the observer with genuine re-presentations of visible objects. The intellect is thus compelled to decipher flat images of no inherent epistemic value, accidental effects of a purely causal process, as vague, reversed reflections of wholly independent objects. Reflecting on and trespassing the boundaries between natural and artificial, orderly and disorderly, this optical paradox (...) is a Baroque phenomenon; and it is the origin of Descartes’ celebrated doubt---whether we know anything at all.

Determining Risk Factors and Demographic Patterns of Suicide in Tehran Suicide refers to the death of a person that is primarily achieved by self-harm. Today, it is considered one of the major public health issues. One of the important risk factors associated with attempted suicide is social relations. This study is a descriptive and analytical study that aims to identify the suicide rate, the risk factors in suicide, and the methods of suicide. The findings show that there is a significant (...) relationship between suicide and demographic variables that include age, sex, educational level, adherence to religion, and occupation. This research also shows the psychological factors that lead to suicide include depression, addiction, lack of social activities, and mental disorders caused by chronic disease. (shrink)

Abstrak: Etika keduniawian Hannah Arendt muncul dari cara khasnya memikirkan dunia dan tindakan-tindakan manusia di dalamnya. Bagi Arendt, lewat berpikir, manusia mengungkapkan opini dan perhatiannya pada dunianya, apa yang terjadi di dunia. Lewat berpikir, manusia menunjukkan sebentuk tanggung jawabnya terhadap dunia dimana ia terlempar. Dengan menilai sebuah tindakan politik, manusia disetir oleh nilai-nilai moral yang berasal dari dunia itu sendiri. Penilaian yang ia berikan, pada gilirannya ada di bawah putusan orang-orang lain yang mengkonfrontasinya. Artinya, saat kita berpikir dan menilai, kita (...) mesti sadar akan makna tindakan politis bagi dunia pada umumnya, dan kita juga mesti menyadari apa yang akan dikatakan orang lain tentangnya. Kata-kata Kunci: Etika, keduniawian, berpikir, menilai, tanggungjawab. Abstract: This paper aims at reconstructing Arendt’s ethics of worldliness from her specific way of thinking about the world and how to judge an action takes place in it. For Arendt, in thinking, we express our concern and opinion about the world and what is going on in it. It is one way of showing our responsibility for the world into which we are thrown. In judging a political action we are directed by ethical constraints to come from the world itself and the verdict of spectators. That means, when we judge we should be aware of the things that an action could bring to the public realm and what others might say about it. Keywords: Ethics, worldliness, thinking, judging, responsibility. (shrink)
