This paper focuses on weather and climate as factors affecting certain facets of human activity during the Byzantine period. Various aspects of impact that weather phenomena and climatic conditions could have upon travel, travellers and communications by land, either in short-term or in long-term context, during the Byzantine period are discussed: Were there any long-term impacts of climatic change upon communications overland? Which weather phenomena are described by the Byzantine authors as affecting people on move? What was the impact of (...) weather upon land transport and communications? Which was the concept of weather that people on the move had and how can we combine weather reports with traveller's emotional and factual reality while experiencing meteorologically induced dangers during overland travel?

Deep brain stimulation of the subthalamic nucleus or the globus pallidus is an established treatment for Parkinson’s disease that yields a marked and lasting improvement of motor symptoms. Yet, DBS benefit on gait disturbances in PD is still debated and can be a source of dissatisfaction and poor quality of life. Gait disturbances in PD encompass a variety of clinical manifestations and rely on different pathophysiological bases. While gait disturbances arising years after DBS surgery can be related to disease progression, (...) early impairment of gait may be secondary to treatable causes and benefits from DBS reprogramming. In this review, we tackle the issue of gait disturbances in PD patients with DBS by discussing their neurophysiological basis, providing a detailed clinical characterization, and proposing a pragmatic programming approach to support their management.

Wells's The New Machiavelli (1911) offers an excellent case study of the use of anti-Machiavellian Machiavellism as both a philosophical and a rhetorical strategy. In Remington, Wells creates a protagonist who follows Machiavellian rules of behaviour and denounces those who do likewise. The novel is structured to show Remington's progress from an idealist refutation of Machiavellism, through a recognition of its necessity, to the formulation of a private and political method for the necessary pursuit of Machiavellian principles under the disguise (...) of anti-Machiavellism, including trenchant criticisms of Fabians as anti-Machiavellian Machiavellians. These stages, culminating in complete personal and public failure, are reflected in Remington's party allegiances, and broadened by Wells into an account of British party ideologies around the turn of the twentieth century. Wells's rhetorical design for mapping and assessing anti-Machiavellian Machiavellism is paralleled by an exploration of that technique in himself, attested by the predominance of autobiographical elements in The New Machiavelli, and by similarities between Remington's and Wells's own deception of others and themselves. Far from incidental, anti-Machiavellian Machiavellism is the motif that unites the shifting party allegiances, political conceits and moral hypocrisies, and private and public failures of Wells, Remington, and of the period of British politics that they intend to encapsulate.

This paper seeks to examine the relationship and the interaction between institutions, policy and the labour market in the light of the ideas of the first generation of institutional economists, who, in contrast to neoclassicals, conceived of the economy as a nexus of institutions, underlining, therefore, the significant role of institutional and non-market factors in the functioning of an economic system. They also criticised those who define (economic) welfare only in terms of efficiency and satisfaction of consumer interests; institutionalists instead (...) focus on issues related to justice, human self-development and labourers' welfare. In addition, early institutionalists paid considerable attention to the institutional framework of the labour market. In particular, the first generation of institutional economists highlighted the importance of institutions and other non-market parameters in determining the level of wages and employment (e.g. the role of the bargaining power of workers and employers). Furthermore, they made substantial contributions towards the field of labour policy and they were pioneers in the formulation of economic and social policy. Specifically, various modern institutions and labour market policies, such as unemployment benefits, industrial training and active employment policies, were implemented in the US, during the first decades of the 20th century, after the recommendation of the institutional labour economists. Therefore, their ideas, besides being interesting from a historical point of view, may also be useful in today's analysis of workers' problems and the functioning of modern labour markets. (shrink)

An anonymous oration, praising the emperor Manuel II Palaiologos, has been recently published by Ch. Dendrinos, who treats it as a funeral oration. However, it is evident that the emperor was still alive at the time of the composition of that text, so we can safely assume that it was intended as a an encomium of the ruling emperor, and it was written some time after the death of the emperor's nephew John VII Palaiologos (1408). On the basis of some (...) textual parallels between that anonymous text and the works of Makarios we put forward the hypothesis that the text published by Dendrinos was written by Makres himself. Finally an anonymous text praising Manuel II Palaiologos, attributed to Isidore of Kiev by G. Mercati, is published for the first time. That piece of oratory was composed shortly after Manuel's return from the West (1403). (shrink)

In Plato’s Parmenides 132a-133b, the widely known Third Man Paradox is stated, which has special interest for the history of logical reasoning. It is important for philosophers because it is often thought to be a devastating argument to Plato’s theory of Forms. Some philosophers have even viewed Aristotle’s theory of predication and the categories as inspired by reflection on it [Owen 1966]. For the historians of logic it is attractive, because of the phenomenon of self-reference that involves. Bocheński denies any (...) possibility of correct logical reasoning before Aristotle. In particular, he flatly declares of Plato that “correct logic we find none in his work” [1951, 15]. In this line, many papers have been written that call attention to the violation of a metalogical principle – the type rules – because of the Third Man Paradox. The problem of interpretation of the paradox raised many discussions, since the 50’s, and the literature devoted to this topic is today enormous. Nevertheless, many points in Plato’s reasoning remain obscure. Hitherto, it is commonly believed that the paradox was simply stated by Plato in his "Parmenides", but not actually solved. Even more, it is believed that it is hardly possible for Plato to have suggested a solution, because he confused the categories of substance and attribute. B. Russell has also argued that Plato violates in his arguments the restrictions imposed on language by the theory of logical types. This view is encouraged by the linguistic difficulties, which Plato has faced in his attempt to formulate an ontology of abstract entities, i.e. that in Greek language abstract and concrete terms are formally indistinguishable [Kneales 1984]. In this paper, we analyse the logical structure of the argument in an attempt to give a systematic consistent reconstruction of the text appealing to methods and concepts of modern logic and semantics. Already in 1954 G. Vlastos had noted in his seminal paper “The ‘Third Man’ Argument in the Parmenides” that “if any progress … is to be made at this juncture it must come from some advance in understanding the logical structure of the Argument”. Accordingly, our analysis is primarily focused on the line of logical reasoning, rather than the metaphysical underpinnings and philosophical implications of the paradox for Plato’s theory of Forms. We divide the Platonic text into three parts, presenting apparent thematic coherence: a) Formulation of the Third Man Paradox (132a-132b). The central issue of this part is a step-like generation of Forms that can continue ad infinitum. b) Discussion of the paradoxical situation (132b-c), by passing to the use of terminology echoing Eleatic philosophy. The concept of “thought” and the underlying semantics of Eleatic origin are central in this passage. c) Solution of the paradox (132d-133a). In our view, this part contains not only a resemblance regress, as most interpretators con-sider, but also the solution of the paradox by the introduction of a sound definition of the concept of “similarity”. We should note that the name ‘Third Man Paradox’ never occurs in Plato, who, strictly speaking, formulates a ‘Third Large Paradox’. The name ‘Third Man Paradox’ appears in the works of Aristotle and the commentators of the Peripatetic tradition. Later commentators have identified Aristotle’s Third Man with Plato’s Third Large Argument. In our paper, we also examine other testimonies about the Third Man Paradox found in the works of commentators in order to illuminate the logical structure of the argument. Although the vocabulary used in these versions is different, they do not affect its logical structure, but rather reveal different understandings by the ancient authors. These testimonies are divided into two main categories: those met in Neo-Platonic authors, notably in Proclus’ "Commentary on Plato’s Parmenides", and the versions of the Third Man Paradox found in texts of the Peripatetic tradition (Eudemus, Aristotle, Alexander). From our discussion, it becomes clear that the approaches to the paradox by the various scholars of antiquity are different, depending also on their participation in the one or the other campus of philosophical thought. We show that the Peripatetic authors are aware of the source of the paradox. However, the first scholar of antiquity who explicitly ascribes a solution to Plato seems to be Proclus. (shrink)

In this paper, we suggest the broader concept of proof-event, introduced by Joseph Goguen, as a fundamental methodological tool for studying proofs in history of mathematics. In this framework, proof is understood not as a purely syntactic object, but as a social process that involves at least two agents; this highlights the communicational aspect of proving. We claim that historians of mathematics essentially study proof-events in their research, since the mathematical proofs they face in the extant sources involve many informal (...) components, often not completely formalizable, and convey some kind of semantic content calling for understanding and verification. We illustrate the application of this methodological approach in some outstanding historical cases, paying particular attention to the process of proof interpretation that makes a proof-event alive. Finally, we suggest a classification of proof-events, according to the conditions imposed upon problem-solving. This enables us to speak about broad classes of proof-events in history of mathematics that share a common characteristic. (shrink)

Does the concept of “race” find support in contemporary science, particularly in biology? No, says Naomi Zack, together with so many others who nowadays argue that human races lack biological reality. This claim is widely accepted in a number of fields (philosophy, biology, anthropology, and psychology), and Zack’s book represents only the latest defense of social constructivism in this context. There are several reasons why she fails to make a convincing case. Zack starts by arbitrarily ascribing an anachronistically essentialist connotation (...) to the concept of race. After having made that everyday notion semantically so crude and outdated there is no wonder that she finds it quite easy to conclude that such an awkward category has no place in science. Her main rationale for seeing our race distinctions as being poorly matched to biological characteristics (e.g., population differences in gene frequencies) is that these biological characteristics do not fall into discrete and mutually exclusive categories as “required” by the common-sense taxonomy. This opposition between the continuity of variation found in biology and the alleged discreteness of common-sense “races” is repeated throughout the book, and it is presented as creating an unbridgeable gap between biology and the colloquial concept of race. Contrary to what Zack says, however, today’s common-sense ideas about race are not so radically disconnected from contemporary science. Rather, “race” in ordinary usage is informed by biological knowledge to a considerable extent. Most people no longer think about race in terms of pre-Darwinian racial “essences” and “mutually exclusive” ideal types. In fact, as pointed out by Anthony Appiah (whom Zack quotes on this matter but without taking him seriously enough), the discourse on race has long been characterized by a practice of “semantic deference,” according to which people tend to use the word “race” assuming that the biologists could say more precisely than they could what it meant..

Main figures in Byzantium after the Byzantium were Ioannis Zygomalas (1498-1584) and his son and fellow Theodosius (1544-1607) who drew a spiritual path that left many and rich traces and presumptions. They served in the Patriarchate of Constantinople in key positions. There they taught the ancient Greek language and they copied and distributed manuscripts of works of ancient and byzantine writers. Their mailing correspondence with European scholars and travelers is well known. Thanks to that, the humanistic Europe met not (...) only the Greek scholars of the 16th c. but also their spoken language of that era, as a continuation of the Greek classical times and the Byzantine world. The historical information concerning them that has been saved is of interest to many categories of specialists of human sciences: Theology and Philosophy, Social History, History of Law and Institutions, Literature and Linguistics, Palaeography and Codicology, Letter-writing.

Does action always arise out of desire? G. F. Schueler examines this hotly debated topic in philosophy of action and moral philosophy, arguing that once two senses of "desire" are distinguished - roughly, genuine desires and pro attitudes - apparently plausible explanations of action in terms of the agent's desires can be seen to be mistaken. Desire probes a fundamental issue in philosophy of mind, the nature of desires and how, if at all, they motivate and justify our actions. At (...) least since Hume argued that reason "is and of right ought to be the slave of the passions," many philosophers have held that desires play an essential role both in practical reason and in the explanation of intentional action. G. F. Schueler looks at contemporary accounts of both roles in various belief-desire models of reasons and explanation and argues that the usual belief-desire accounts need to be replaced. Schueler contends that the plausibility of the standard belief-desire accounts rests largely on a failure to distinguish "desires proper," like a craving for sushi, from so-called "pro attitudes," which may take the form of beliefs and other cognitive states as well as desires proper. Schueler's "deliberative model" of practical reasoning suggests a different view of the place of desire in practical reason and the explanation of action. He holds that we can arrive at an intention to act by weighing the relevant considerations and that these may not include desires proper at all. (shrink)

This paper aims to show that Godel's ontological argument can be parodied in much the same kind of way in which Gaunilo parodied Anselm's Proslogion argument. The parody in this paper fails; there is a patch provided in "Reply to Gettings" (Analysis 60, 4, 2000, 363-7).

ABSTRACT:Neuroethics, the study of the cognitive and neural mechanisms underlying ethical decision-making, is a growing field of study. In this review, we identify and discuss four themes emerging from neuroethics research. First, ethical decision-making appears to be distinct from other types of decision-making processes. Second, ethical decision-making entails more than just conscious reasoning. Third, emotion plays a critical role in ethical decision-making, at least under certain circumstances. Lastly, normative approaches to morality have distinct, underlying neural mechanisms. On the basis of (...) these themes, we draw implications for research in business ethics and the practice of ethics training. (shrink)

This paper is a critical examination of Stephen Neale's *The Philosophical Significance of Godel's slingshot*. I am sceptical of the philosophical significance of Godel’s Slingshot (and of Slingshot arguments in general). In particular, I do not believe that Godel’s Slingshot has any interesting and important philosophical consequences for theories of facts or for referential treatments of definite descriptions. More generally, I do not believe that any Slingshot arguments have interesting and important philosophical consequences for theories of facts or for referential (...) treatments of definite descriptions. Friends of facts and referential treatments of definite descriptions can, and should, proceed with the construction of their theories, blithely ignoring the many Slingshots which now litter the landscape. (Of course, there may be other considerations which should give such theorists pause -- but those are other considerations.). (shrink)

This paper offers a short extension of the dialogue between Anselm and the Fool that is contained in "The Ontological Argument Simplified" by Gary Matthews and Lynne Rudder Baker. My extension of the dialogue ends with the Fool proclaiming that "what looks like an argument of elegant simplicity turns out to be no argument at all".

This article is a reply to Michael Gettings' criticisms of a previous paper of mine on Godel's ontological argument. (All relevant bibliographical details may be found in the article.) I provide a patch to my previous -- faulty -- attempt to provide a parody of Godel's ontological argument on the model of Gaunilo's parody of Anselm's Proslogion 2 argument.

The Ramsey-sentence H* of any hypothesis H is shown to be a synthetic proposition containing mathematics as a finite component. Far from being quasi-tautological, H* proves to have as much physical content as H itself.

I criticise a paper by Peter Forrest in which he argues that a principle of unrestricted countable fusion has paradoxical consequences. I argue that the paradoxical consequences that he exhibits may be due to his Whiteheadean assumptions about the nature of spacetime rather than to the principle of unrestricted countable fusion.

Following Henkin’s discovery of partially-ordered (branching) quantification (POQ) with standard quantifiers in 1959, philosophers of language have attempted to extend his definition to POQ with generalized quantifiers. In this paper I propose a general definition of POQ with 1-place generalized quantifiers of the simplest kind: namely, predicative, or “cardinality” quantifiers, e.g., “most”, “few”, “finitely many”, “exactly α ”, where α is any cardinal, etc. The definition is obtained in a series of generalizations, extending the original, Henkin definition first to a (...) general definition of monotone-increasing (M↑) POQ and then to a general definition of generalized POQ, regardless of monotonicity. The extension is based on (i) Barwise’s 1979 analysis of the basic case of M↑ POQ and (ii) my 1990 analysis of the basic case of generalized POQ. POQ is a non-compositional 1st-order structure, hence the problem of extending the definition of the basic case to a general definition is not trivial. The paper concludes with a sample of applications to natural and mathematical languages. (shrink)

Features of threatening cues and the associated context influence the perceived imminence of threat and the defensive responses evoked. To provide additional knowledge about how the directionality of a threat (i.e. directed-towards or away from the viewer) might impact defensive responses in humans, participants were shown pictures of a man carrying a gun (threat) or nonlethal object (neutral) directed-away from or towards the participant. Cardiac and electrodermal responses were collected. Compared to neutral images, threatening images depicting a gun directed-towards the (...) participant induced sustained bradycardia and an increased electrodermal response, interpreted as immobility under attack. This defensive immobility reaction is evoked by high perceived threat and inescapable situations and indicates intense action preparation. Pictures of guns directed-away from the participant induced shorter bradycardia and no significant modulation of the electrodermal response compared to neutral pictures, which might be consistent with the perception of a less threatening situation. The results show that the directionality of threat stimuli is a key factor that prompts different patterns of defensive responses. (shrink)

Boldly focusing on sexuality as a crucial definer of social order, Being and Symptom argues that there is an "M theory" -- a master theory of theories -- not only in Quantum Physics, but also in Continental Philosophy, Psychoanalysis, and Sociology, disclosing how the ontological structure of the "fantastic four" ingredients of metaphysics (potentiality, impotentiality, actuality, completion) has recurred through time. Öğüt also seeks to turn Thomas Hobbes's political philosophy into a social theory within the fields of sexuality and sovereignty (...) and to locate parallels among Aristotle, Ibn Khaldun, Kant, Hegel, Heidegger, Foucault, Lacan, Agamben, Nash, Derrida, Girard, Kristeva, and Žižek, with a special emphasis on how Žižek has adapted Lacanian psychoanalysis into social theory. Öğüt conveys a highly original analysis of the unconscious of our social (sexual) relations, subjectivities, and politics. (shrink)

In order to study early human development while avoiding the burdens associated with human embryo research, scientists are redirecting their efforts towards so-called human embryo-like structures (hELS). hELS are created from clusters of human pluripotent stem cells and seem capable of mimicking early human development with increasing accuracy. Notwithstanding, hELS research finds itself at the intersection of historically controversial fields, and the expectation that it might be received as similarly sensitive is prompting proactive law reform in many jurisdictions, including the (...) Netherlands. However, studies on the public perception of hELS research remain scarce. To help guide policymakers and fill this gap in the literature, we conducted an explorative qualitative study aimed at mapping the range of perspectives in the Netherlands on the creation and research use of hELS. This article reports on a subset of our findings, namely those pertaining to (the degrees of and requirements for) confidence in research with hELS and its regulation. Despite commonly found disparities in confidence on emerging biotechnologies, we also found wide consensus regarding the requirements for having (more) confidence in hELS research. We conclude by reflecting on how these findings could be relevant to researchers and (Dutch) policymakers when interpreted within the context of their limitations. (shrink)
