This article presents two different phenomenological paths leading from ego to alter ego: a Husserlian and a Merleau-Pontian way of thinking. These two phenomenological paths serve to disentangle the conceptual–philosophical underpinning of the mirror neurons system hypothesis, in which both ways of thinking are entwined. A Merleau-Pontian re-reading of the mirror neurons system theory is proposed, in which the characteristics of mirror neurons are effectively used in the explanation of action understanding and imitation. This proposal uncovers the remaining necessary presupposition (...) of a minimalized version of the Husserlian concept of pairing and its recent and improved version in terms of the intermodal system. This leads to a layered approach to the constitution of intersubjectivity. (shrink)
This paper investigates the role of a pre-existing body-model that is an enabling constraint for the incorporation of objects into the body. This body-model is also a basis for the distinction between body extensions (e.g., in the case of tool-use) and incorporation (e.g., in the case of successful prosthesis use). It is argued that, in the case of incorporation, changes in the sense of body-ownership involve a reorganization of the body-model, whereas extension of the body with tools does not involve (...) changes in the sense of body-ownership.

Main principles of the complex nonlinear thinking which are based on the notions of the modern theory of evolution and self-organization of complex systems called also synergetics are under discussion in this article. The principles are transdisciplinary, holistic, and oriented to a human being. The notions of system complexity, nonlinearity of evolution, creative chaos, space-time definiteness of structure-attractors of evolution, resonant influences, nonlinear and soft management are here of great importance. In this connection, a prominent contribution made to system analysis (...) and to a necessary reform of education and thinking by Edgar Morin is considered. (shrink)
This paper presents a way of classifying different forms of naturalness and unnaturalness. Three main forms of (un)naturalness are found as the following: history- based (un)naturalness, property-based (un)naturalness and relation-based (un)naturalness. Numerous subforms (and some subforms of the subforms) of each are presented. The subforms differ with respect to the entities that are found (un)natural, with respect to their all-inclusiveness, and whether (un)naturalness is seen as all-or-nothing affair, or a continuous gradient. This kind of conceptual analysis is needed, first, because (...) discussion concerning (un)naturalness is common in current bioethics and environmental ethics, and second, because the terms natural and unnatural are highly ambiguous. Thus, the lack of an exact definition of the type of (un)naturalness may lead into equivocation, other forms of bad argumentation, or at least vagueness. (shrink)

Using three paradigm cases of persons living with Parkinson's Disease (PD) the authors make a case for augmenting and enriching a Cartesian medical account of the pathophysiology of PD with an enriched understanding of the lived body experience of PD, the lived implications of PD for a particular person's concerns and coping with the illness. Linking and adding a thick description of the lived experience of PD can enrich caregiving imagination and attunement to the patient's possibilities, concerns and constraints. The (...) work of Merleau-Ponty is used to articulate the middle terms of the lived experience of dwelling in a lifeworld. Examining lived experience of embodied intentionality, skilled bodily capacities as highlighted in Merleau-Ponty's non-mechanistic physiology opens new therapeutic, coping and caregiving possibilities. Matching temporal rhythms can decrease the stress of being assisted with activities of daily living. For example, caregivers and patients alike can be taught strategies for extending their lived bodily capacities by altering rhythms, by shifting hyperactivity to different parts of the body and other strategies that change the perceptual experience associated with walking in different environment. A medical account of the pathophysiology of PD is nessessary and useful, but not sufficient for designing caregiving in ways that enrich and extend the existential skills of dwelling of persons with PD. The dominance of mechanistic physiology makes caregivers assume that it is the 'real discourse' about the disease, causing researchers and caregivers alike to overlook the equally real lived experience of the patient which requires different descriptive discourses and different sources of understanding. Lack of dialogue between the two discourses is tragic for patients because caregivers need both in order to provide attuned, effective caregiving. (shrink)
While the question of whether selected-effects accounts of function or causal-role accounts of function provide the ‘true' functional analysis has given way to a general pluralistic consensus, Philip Kitcher has suggested that different functional accounts allow for unification. I argue that Kitcher's attempt to unify the two functional analyses fails because he adopts the environment-centered perspective on selection as a premise. The premise is undermined by the role niche construction is likely to play in the context of evolution. Moreover, I (...) raise the tentative suggestion that niche construction may threaten the applicability, or at least the relevance, of selected-effects ascriptions. *Received October 2009; revised May 2010. †To contact the author, please write to: Institut für Philosophie Fakultät für Philosophie und Bildungswissenschaft, Universität Wien, Universitätsstraße 7 1010 Wien, Austria; e-mail: Adela.Roszkowski@univie.ac.at.

This article argues for a more rigorous distinction between body extensions on the one hand and incorporation of non-bodily objects into the body on the other hand. Real re-embodiment would be a matter of taking things (most often technologies) into the body, i.e. of incorporation of non-bodily items into the body. This, however, is a difficult process often limited by a number of conditions of possibility that are absent in the case of ‘mere’ body extensions. Three categories are discussed: limb (...) extensions/prostheses, perceptual extensions/prostheses and cognitive extensions/prostheses. For each category, a distinction between extensions and incorporations is proposed, and the conditions of possibility for real incorporation are discussed. These conditions of possibility differ in each category, but in general they ask for radical or fundamental alterations not only in the motor and/or sensory or cognitive constitution of a human subject, but also in his or her subjective experience.

Several recent accounts claim that imagination is a matter of simulating perceptual acts. Although this point of view receives support from both phenomenological and empirical research, I claim that Jean-Paul Sartre's worry formulated in L'imagination (1936) still holds. For a number of reasons, Sartre heavily criticizes theories in which the sensory material of imaginative acts consists in reviving sensory impressions. Based on empirical and philosophical insights, this article explains how simulation theories of imagination can overcome Sartre's critique by paying attention (...) to the motor dimension of imagination. Intending to clarify the status of the sensory in imagination, a motor theory of imagination is presented in which the sensory component of imagination is interpreted in terms of anticipated sensory consequences of preparation for motor action.

Richard Tieszen [Tieszen, R. (2005). Philosophy and Phenomenological Research, LXX(1), 153–173.] has argued that the group-theoretical approach to modern geometry can be seen as a realization of Edmund Husserl’s view of eidetic intuition. In support of Tieszen’s claim, the present article discusses Husserl’s approach to geometry in 1886–1902. Husserl’s first detailed discussion of the concept of group and invariants under transformations takes place in his notes on Hilbert’s Memoir Ueber die Grundlagen der Geometrie that Hilbert wrote during the winter 1901–1902. (...) Husserl’s interest in the Memoir is a continuation of his long-standing concern about analytic geometry and in particular Riemann and Helmholtz’s approach to geometry. Husserl favored a non-metrical approach to geometry; thus the topological nature of Hilbert’s Memoir must have been intriguing to him. The task of phenomenology is to describe the givenness of this logos, hence Husserl needed to develop the notion of eidetic intuition. (shrink)
The phenomenological tradition has had a long interest in embodiment, and bodily experience beyond the confines of the “skinbag” body. Here I respond to Helena De Preester’s analysis of different types of protheses: limb, perceptual, cognitive. In her paper “Technology and the body: the (im)possibilities of re-embodiment”, she wants to make finer distinctions between extensions and incorporations . Today’s hi-tech developments make this refinement necessary and possible. I respond to the three levels or types of prostheses taking note of (...) the increasing difficulty at each level and express certain worries about cognitively framed notions of bodily experience.

Rousseau and Geneva reconstructs the main aspects of Genevan socio-economic, political and religious thought in the first half of the eighteenth century. In this way Dr Rosenblatt effectively contextualizes the development of Rousseau's thought from the First Discourse through to the Social Contract. Over time Rousseau has been adopted as a French thinker, but this adoption obscures his Genevan origin. Dr Rosenblatt points out that he is, in fact, a Genevan thinker and illustrates for the first time that Rousseau's classical (...) republicanism, his version of natural law theory, his civil religion, and his hostility to the arguments of doux commerce theorists are all responses to the political use of such arguments in Geneva. The author also points out that it was this relationship with Geneva that played an integral part in his development into an original political thinker. (shrink)
Husserl’s notion of definiteness, i.e., completeness is crucial to understanding Husserl’s view of logic, and consequently several related philosophical views, such as his argument against psychologism, his notion of ideality, and his view of formal ontology. Initially Husserl developed the notion of definiteness to clarify Hermann Hankel’s ‘principle of permanence’. One of the first attempts at formulating definiteness can be found in the Philosophy of Arithmetic, where definiteness serves the purpose of the modern notion of ‘soundness’ and leads Husserl to (...) a ‘computational’ view of logic. Inspired by Gauss and Grassmann Husserl then undertakes a further investigation of theories of manifolds. When Husserl subsequently renounces psychologism and changes his view of logic, his idea of definiteness also develops. The notion of definiteness is discussed most extensively in the pair of lectures Husserl gave in front of the mathematical society in Göttingen (1901). A detailed analysis of the lectures, together with an elaboration of Husserl’s lectures on logic beginning in 1895, shows that Husserl meant by definiteness what is today called ‘categoricity’. In so doing Husserl was not doing anything particularly original; since Dedekind’s ‘Was sind und sollen die Zahlen’ (1888) the notion was ‘in the air’. It also characterizes Hilbert’s (1900) notion of completeness. In the end, Husserl’s view of definiteness is discussed in light of Gödel’s (1931) incompleteness results. (shrink)
Body integrity identity disorder (BIID), formerly also known as apotemnophilia, is characterized by a desire for amputation of a healthy limb and is claimed to straddle or to even blur the boundary between psychiatry and neurology. The neurological line of approach, however, is a recent one, and is accompanied or preceded by psychodynamical, behavioural, philosophical, and psychiatric approaches and hypotheses. Next to its confusing history in which the disorder itself has no fixed identity and could not be classified under a (...) specific discipline, its sexual component has been an issue of unclarity and controversy, and its assessment a criterion for distinguishing BIID from apotemnophilia, a paraphilia. Scholars referring to the lived body—a phenomenon primarily discussed in the phenomenological tradition in philosophy—seem willing to exclude the sexual component as inessential, whereas other authors notice important similarities with gender identity disorder or transsexualism, and thus precisely focus attention on the sexual component. This contribution outlines the history of BIID highlighting the vicissitudes of its sexual component, and questions the justification for distinguishing BIID from apotemnophilia and thus for omitting the sexual component as essential. Second, we explain a hardly discussed concept from Maurice Merleau-Ponty’s Phenomenology of Perception ( 1945a ), the sexual schema , and investigate how the sexual schema could function in interaction with the body image in an interpretation of BIID which starts from the lived body while giving the sexual component its due.

The modern conception of enactive cognition is under discussion from the standpoint concerning the notions of nonlinear dynamics and synergetics. The contribution of Francisco Varela and his precursors is considered. It is shown that the perceptual and mental processes are bound up with the “architecture” of human body and nonlinear and circular connecting links between the subject of cognition and the world constructed by him can be metaphorically called a nonlinear cobweb of cognition. Cognition is an autopoietic activity because it (...) is directed to the search of elements that are missed; it serves to completing integral structures. (shrink)
Conservation scientists are arguing whether naturalness provides a reasonable imperative for conservation. To clarify this debate and the interpretation of the term natural, I analyze three management strategies – ecosystem preservation, ecosystem restoration, and ecosystem engineering – with respect to the naturalness of their outcomes. This analysis consists in two parts. First, the ambiguous term natural is defined in a variety of ways, including (1) naturalness as that which is part of nature, (2) naturalness as a contrast to artifactuality, (3) (...) naturalness as an historical independence from human actions, and (4) naturalness as possession of certain properties. After that, I analyze the different conceptions with respect to their implications for the three management strategies. The main conclusion is that there exists no single conception of naturalness that could distinguish between the outcomes of the three management methods. Therefore, as long as the outcomes of the different methods are regarded as being of a different value in conservation, we should either abandon the idea of naturalness as the guiding concept in conservation or use the term natural only in the ways that take both its historical and feature dependent meanings into consideration.

Today a change is imperative in approaching global problems: what is needed is not arm-twisting and power politics, but searching for ways of co-evolution in the complex social and geopolitical systems of the world. The modern theory of self-organization of complex systems provides us with an understanding of the possible forms of coexistence of heterogeneous social and geopolitical structures at different stages of development regarding the different paths of their sustainable co-evolutionary development. The theory argues that the evolutionary channel to (...) the observed increasing complexity is extremely narrow and only certain discrete spectra of relatively stable self-maintained structures are feasible in complex systems. There exists a restricted set of ways of assembling a complex evolutionary whole from diverse parts. The law of nonlinear synthesis of complex structures reads: the integration of structures in more complex ones occurs due to the establishment of a common tempo of their evolution. On the basis of the theory, we can see not only desirable but also attainable futures. (shrink)
This article outlines the distinctive contribution of Marxism to science studies. It traces the trajectory of Marxist ideas through the decades from the origins of Marxism to the present conjuncture. It looks at certain key episodes, such as the arrival of a Soviet delegation at the International History of Science Congress in London in 1931, as well as subsequent interactions between Marxists and exponents of other positions at later international congresses. It focuses on the impact of several generations of Marxists (...) who have engaged with science in diverse ways. It examines the influence of Marxism on contemporary trends in science studies. It concludes that Marxism survives in circuitous and complex ways. It argues not only for a positive interpretation of its contribution in the past but for its explanatory and ethical power in the present and future. (shrink)
The European Union’s policies regarding genetically modified food (GMF hereafter) are based on the precautionary principle and the requirement of respecting consumers’ autonomy. We ask whether the requirement of respecting consumers’ autonomy regarding GMF implies that both GMF and non-GMF products should be available in the market. According to one line of thought, consumers’ choices may be autonomous even when the both types of products are not available. A food market with only GMF or only non-GMF products does not strictly (...) speaking compel people to buy the type of products available, and a possibility to refuse to buy is enough for consumers’ choice to be autonomous. According to another line of thought, the unavailability of GMF or non-GMF products restricts the autonomy of those consumers who are unwilling to use the only type of products (GMF or non-GMF) available in the market. From the point of view of autonomy, a food market with only GMF or only non-GMF products does not offer enough alternatives for consumers. Moreover, the whole point of the European Union’s requirement of respecting consumers’ autonomy is to enable an autonomous choice between GMF and non-GMF—not just to give a possibility to refrain from buying. However, this does not imply that producers, processors, wholesalers, retailers, or public authorities have a moral duty to see that there are both GMF and non-GMF products available in the market. The requirement to respect autonomy is prima facie in nature, and in the context of GMF, other prima facie requirements are often stronger and override it. Not only the consumers’ autonomy of choice but also environmental values, other people’s well-being, and the autonomous choice of farmers, retailers, and other relevant parties should be respected. Thus, according to the both lines of thought, the requirement to respect consumers’ autonomy of choice does not imply that there should be both GMF and non-GMF products available in the market.

The philosophical consequences of synergetics, the interdisciplinary theory of evolution and self-organization of complex systems, are being drawn in the paper. The idea of discreteness of evolutionary paths is in the focus of attention. Although the future is open, and there are many alternative evolutionary paths for complex systems, not any arbitrary (either conceivable or desirable) evolutionary path is feasible in a given system. There are discrete spectra of possible evolutionary paths which are determined exclusively by inner properties of the (...) corresponding systems. Synergetics allows us to reveal general laws of self-organization and, therefore, certain limits of arbitrariness of nature in choosing possible paths of evolution as well as in constructing of a complex evolutionary whole. A comparative analysis between the modern synergetic notions and a few ideas of the Western philosophy (F. Nietzsche, N. Hartmann, M. Heidegger) and of the Eastern teachings (Taoism, Buddhism) is made. (shrink)
Individuals’ food choices are intimately connected to their self-images and world views. Some dietary choices adopted by consumers pose restrictions on their use of genetically modified food (GMF). It is quite generally agreed that some kind of labeling is necessary for respecting consumers’ autonomy of choice regarding GMF. In this paper, we ask whether the current practice of mandatory labeling of GMF products in the European Union is a sufficient administrative procedure for respecting consumers’ autonomy. Three issues concerning this question (...) are discussed. First, we argue that labeling needs to be accompanied by relevant and understandable information on genetic modification, genetically modified food, and the European practice of GMF labeling. Second, we claim that this type of informing makes it less likely that consumers start to avoid GMF products just because labels make them suspicious of the products. It is further noted that even though some consumers may react to labels this way, labels do not restrict their autonomy of choice. Third, a need for more precise labels indicating the source of the transferred gene is considered. It is found out that such labels are not morally necessary when also non-GMF products are available and no relevant differences (such as differences in price and healthiness) exist between them and GMF products. However, in some other cases more precise labels may be needed for respecting consumers’ autonomy of choice. (shrink)
This paper analyses the actual meaning of a transcendental philosophy of biology, and does so by exploring and actualising the epistemological and metaphysical value of Kant's viewpoint on living systems. It finds inspiration in the Kantian idea of living systems intrinsically resisting objectification, but critically departs from Kant's philosophical solution in as far as it is based in a subjectivist dogmatism. It attempts to overcome this dogmatism, on the one hand by explicitly taking into account the conditions of possibility at (...) the side of the subject, and on the other hand by embedding both the living and the knowing system into an ontology of complexly organized dynamical systems. This paper fits into the transcendental perspective in acknowledging the need to analyse the conditions of knowability, prior to the contents of what is known. But it also contributes to an expansion and an actualisation of the issue of transcendentality itself by considering the conditions of possibility at the side of the object as intrinsically linked to the conditions of possibility at the side of the subject.

The introduction of new medical treatments based on invasive technologies has often been surrounded by both hopes and fears. Hope, since a new intervention can create new opportunities either in terms of providing a cure for the disease or impairment at hand; or as alleviation of symptoms. Fear, since an invasive treatment involving implanting a medical device can result in unknown complications such as hardware failure and undesirable medical consequences. However, hopes and fears may also arise due to the cultural (...) embeddedness of technology, where a therapy due to ethical, social, political and religious concerns could be perceived as either a blessing or a threat. While Deep Brain Stimulation (DBS) for treatment resistant depression (TRD) is still in its cradle, it is important to be proactive and try to scrutinize both surfacing hopes and fears. Patients will not benefit if a promising treatment is banned or avoided due to unfounded fears, nor will they benefit if DBS is used without scrutinizing the arguments which call for caution. Hence blind optimism is equally troublesome. We suggest that specificity, both in terms of a detailed account of relevant scientific concerns as well as ethical considerations, could be a way to analyse expressed concerns regarding DBS for TRD. This approach is particularly fruitful when applied to hopes and fears evoked by DBS for TRD, since it can reveal if our comprehension of DBS for TRD suffer from various biases which may remain unnoticed at first glance. We suggest that such biases exist, albeit a further analysis is needed to explore this issue in full. (shrink)
This paper analyzes business people's attitudes towards the tactics used for gathering competitive corporate intelligence both within their own and their competitors' corporations. Business people in large corporations are highly motivated to gather such intelligence. Their attitudes towards the ethicality of specific practices, however, are influenced by the corporate culture, their perceived effectiveness of the techniques, and their perception of the competitors' tactics. Interestingly enough, the most popular technique for securing information is socializing with competitors in nonbusiness settings. Business people (...) generally view their competitors negatively, believing that they go to much further lengths than does their own corporation in gathering competitive intelligence. (shrink)
The hope of finding new methods of predicting the course of historical processes could be connected with the recent developments of the theory of self-organisation, also called synergetics. It provides us with knowledge of constructive principles of co-evolution of complex social systems, co-evolution of countries and geopolitical regions being at different stages of development, integration of the East and the West, the North and the South. Due to the growth of population on the Earth in blow-up regime, the general and (...) local instability of development is increasing. The social world seems to go towards a unity, a sustainable commonwealth through pulsations rather than monotonously. It goes via alternation of disintegration, even if partial, and getting more powerful integrations of structures. There is a path of multiple reduction of temporal and material expenses, a path of a resonant excitation of desirable and — no less important — feasible in a given social system structure. In the case of the right topology of integration of geopolitical structures an arising whole organisation can accelerate its tempo of evolution. 1999 Elsevier Science Ltd. All rights reserved.

The dynamic approach to understanding of the human consciousness, its cognitive activities and cognitive architecture is one of the most promising approaches in the modern epistemology and cognitive science. The conception of embodied mind is under discussion in the light of nonlinear dynamics and of the idea co-evolution of complex systems developed by the Moscow scientific school. The cognitive architecture of the embodied mind is rather complex: data from senses and products of rational thinking, the verbal and the pictorial, logic (...) and intuition, the analytical and synthetic abilities of perception and of thinking, the local and the global, the analogue and the digital, the archaic and the post-modern are intertwined in it. In the process of cognition, co-evolution of embodied mind as an autopoietic system and its surroundings takes place. The perceptual and mental processes are bound up with the structure of human body. Nonlinear and circular connecting links between the subject of cognition and the world constructed by him can be metaphorically called a nonlinear cobweb of cognition. Cognition is an autopoietic activity because it is directed to the search of elements that are missed; it serves to completing integral structures. According to the theory of blow-up regimes in complex systems elaborated by Sergey P.Kudyumov and his followers, the idea of co-evolution is connected with the concept of tempoworlds. To co-evolve means to start to develop in one and the same tempoworld and to use the possibility – in case of a proper intergation into a whole structure – to accelerate the tempo of evolution. The cognitive activities of the human being can be considered as a movement (active walk) in landscapes of co-evolution when he cognizes and changes environment and is changed himself by the very activities. The similar conclusion can be drawn from Francisco Varela’s conception of enactive cognition. (shrink)

soft servants of durable material: they live without pretension in complicated relays and electrical circuits. Speed, docility are their strength. One asks: “What is 2 × 2?”—“Are you a machine?” They answer or refuse to answer, depending on what you demand. There are, however, other machines as well, more abstract automatons, bolder and more inaccessible, which eat their tape in mathematical formulae. They imitate in language. In infinite loops, farther and farther back in their retreat towards more subtle algorithms, more (...) recursive functions. They are logical and describe themselves.

The concept of animal welfare refersto the animal''s quality of life. The choice ofdefinition always reflects some basicvaluation. This makes a particular conceptionof welfare value-dependent. Also, the animalhusbandry system reflects certain values oraims. The values reflected in the chosenconception of animal welfare ought tocorrespond to values aimed for in the husbandrysystem. The IFOAM Basic Standards and otherwritings dealing with organic animal husbandryshould be taken as a departure point for adiscussion of how to interpret the conceptionof welfare in organic farming systems. (...) Theconception of welfare is related to two corevalues in the organic agriculture movement.These core values should be considered in termsof (1) aim for holistic view and (2) aim forsustainability. A third, implicit core value,based on bio- and ecocentric views: (3) respectfor nature is needed as a supplement to thesetwo core values. There are importantimplications of these core values for an``organic'''' conception of animal welfare and forconfronting two dilemmas due to conflictinginterests. Comparisons among the three commonlyused welfare definitions will show thesuperiority of the third approach, which canprovide an outline for a conception of animalwelfare more suitable for organic farmingsystems. This outline combines a holisticecocentric approach with respect for theindividual animal, and it can be used as thebasis for a complex definition with emphasis onnatural behavior. Such a systemic approachconsiders welfare in relation to differentsystemic levels. The systemic view also offerspossibilities for resolving the dilemmas in newways. (shrink)
Algebraic approach to study of classical and non-classical logical calculi was developed and systematically presented by Helena Rasiowa in [48], [47]. It is very fruitful in investigation of non-classical logics because it makes possible to study large families of logics in an uniform way. In such research one can replace logics with suitable classes of algebras and apply powerful machinery of universal algebra. In this paper we present an overview of results on interpolation and definability in modal and positive (...) logics,and also in extensions of Johansson's minimal logic. All these logics are strongly complete under algebraic semantics. It allows to combine syntactic methods with studying varieties of algebras and to flnd algebraic equivalents for interpolation and related properties. Moreover, we give exhaustive solution to interpolation and some related problems for many families of propositional logics and calculi. (shrink)
After a brief introduction to Kuipers' views on explanations of laws we argue that micro-explanations of laws can have two formats: they work either by aggregation and transformation (as Kuipers suggests) or by means of function ascriptions (Kuipers neglects this possibility). We compare both types from an epistemic point of view (which information is needed to construct the explanation?) and from a means-end perspective (do both types serve the same purposes? are they equally good?).
Owing to intensive development of the theory of self-organization of complex systems called also synergetics, profound changes in our notions of time occur. Whereas at the beginning of the 20th century, natural sciences, by picking up the general spirit of Einstein's theory of relativity, consider a geometrization as an ideal, i.e. try to represent time and force interactions through space and the changes of its properties, nowadays, at the beginning of the 21st century, time turns to be in the focus (...) of attention. It turns to be possible to represent space through time, because synergetics shows that historical and evolutionary stages of development of a complex structure can be found now, in its present spatial configuration. A whole series of paradoxical notions, such as “the influence of the future upon the present”, a “possibility of touching of a rather remote future today”, “availability of the past and the future now, in praesenti”, “irreversibility and elements of reversibility in the course of evolutionary processes in time”, “discrete unites, quanta of time”, appear in synergetics.

A first order uncountably valued logicL Q(0,1) for management of uncertainty is considered. It is obtained from approximation logicsL T of any poset type (T, ) (see Rasiowa [17], [18], [19]) by assuming (T, )=(Q(0, 1), ) — whereQ(0, 1) is the set of all rational numbersq such that 0q is the arithmetic ordering — by eliminating modal connectives and adopting a semantics based onLT-fuzzy sets (see Rasiowa and Cat Ho [20], [21]). LogicL Q(0,1) can be treated as an important (...) case ofLT-fuzzy logics (introduced in Rasiowa and Cat Ho [21]) for (T, )=(Q(0, 1), ), i.e. asLQ(0, 1)-fuzzy logic announced in [21] but first examined in this paper.L Q(0,1) deals with vague concepts represented by predicate formulas and applies approximate truth-values being certain subsets ofQ(0, 1). The set of all approximate truth-values consists of the empty set ø and all non-empty subsetss ofQ(0, 1) such that ifqs andqq, thenqs. The setLQ(0, 1) of all approximate truth-values is uncountable and covers up to monomorphism the closed interval [0, 1] of the real line.LQ(0, 1) is a complete set lattice and therefore a pseudo-Boolean (Heyting) algebra. Equipped with some additional operations it is a basic plain semi-Post algebra of typeQ(0, 1) (see Rasiowa and Cat Ho [20]) and is taken as a truth-table forL Q(0,1) logic.L Q(0,1) can be considered as a modification of Zadeh's fuzzy logic (see Bellman and Zadeh [2] and Zadeh and Kacprzyk, eds. [29]). The aim of this paper is an axiomatization of logicL Q(0,1) and proofs of the completeness theorem and of the theorem on the existence ofLQ(0, 1)-models (i.e. models under the semantics introduced) for consistent theories based on any denumerable set of specific axioms. Proofs apply the theory of plain semi-Post algebras investigated in Cat Ho and Rasiowa [4]. (shrink)
Neste texto analisamos blogs da Internet como espaços educativos nos quais se produzem/constroem as identidades juvenis de indivíduos que buscam se inserir no grupo cultural conhecido como nerd/geek. Inseridos nos Estudos Culturais, na sua vertente pós-moderna e pós-estruturalista, valemo-nos da noção de Representação Cultural para analisar como as identidades são constituídas com a escrita/leitura de blogs disponibilizados na web. Destacamos que a forma como se dá o agrupamento dos jovens que escrevem/leem os blogs é efêmera e espontânea, baseada no prazer (...) de estar junto, no consumo de alguns itens e no estabelecimento de alguns laços afetivos momentâneos. Tal compartilhamento tem semelhança com outras “tribos” urbanas deste início de século XXI. Destacamos, também, que não estamos associando a juventude a uma faixa etária particular, mas, isto sim, a um estilo de vida fortemente ligado ao lazer e ao consumo. Os blogs analisados, ao colocarem em circulação representações de identidades nerd/geek, contribuem para a produção discursiva dessas mesmas identidades em função dos modos como os/as integrantes desse grupo partilham formas de apropriar-se de saberes diversos, de utilizar equipamentos tecnológicos, de consumir produtos comerciais e textos midiáticos.

In order to develop further the methods of scenario building and to facilitate the paths towards desirable and sustainable futures, we cannot do without a nonlinear evolutionary thinking. The theory of self-organization of complex systems, called also synergetics, is a scientific basis for such a thinking, the main principles of which are under consideration in the paper. Synergetics provides us with the knowledge of constructive principles of coevolution of the complex social systems, coevolution of countries and geopolitical regions being at (...) different stages of development, integration of the East and the West, the North and the South.

The heuristic value of synergetic models of evolving and self-organizing complex systems as well as their application to epistemological problems is shown in this paper. Nonlinear synergetic models turn out to be fruitful in comprehending epistemological problems such as the nature of human creativity, the functioning of human intuition and imagination, the historical development of science and culture. In the light of synergetics creative thinking can be viewed as a selforganization and self-completion of images and thoughts, filling up gaps in (...) the nets of knowledge. Insight, fast and sudden solutions of scientific problems, instabilities when “an idea is in the air” are considered as examples of blow-up regimes in the cognitive field. (shrink)
Introduction: All countries face theissue of choice in healthcare. Allocation ofhealthcare resources is clearly associated withthe concept of distributive justice and to theexistence of a right to healthcare.Nevertheless, there is still the question ofwhether this right should include all types ofhealthcare services or if it should be limitedto selected types. It follows that choices mustbe made, priorities must be set and thatefficiency of healthcare services should bemaximum.
What happens to education when the potential it helps realizing in the individual works against the formal purposes of the curriculum? What happens when education becomes a vehicle for its own subversion? As a subject-forming state apparatus working on ideological speciesism, formal education is engaged in both human and animal stratification in service of the capitalist knowledge economy. This seemingly stable condition is however insecured by the animal rights activist as undercover learner and—worker, who enters education and research laboratories under (...) false premises in order to extract the knowledge necessary to dismantle the logic of animal utility on which the scientific-educational apparatus rests. The present article is based on a semi-structured interview with an undercover worker. It draws on a synthesis of critical education and posthumanist theories to configure knowledge creation and subjectification processes in the “negative spaces” of education. The techne of undercover work includes mnemotechnical and prosthetic devices, calculation of risk, and mimetic labor. The article argues that the agenda of the undercover worker generates a multi-strained mimetic complex that composes a parasitic educational subject-assemblage redirecting scientific knowledge away from the animal stratification logic of the knowledge economy into different viral circuits; different lines of flight. It invites a rearticulation of the formal education state apparatus in more indeterminate directions, provoking scientific-educational knowledge-practices to become a catalytic impulse for their own disintegration.

Decline of biodiversity—richness, variety and variability of living beings—is an issue of concern world wide. Nevertheless, not all biological diversity is valued by conservation biologists. Most of them reject an idea of creation of so called A-areas—i.e. maximally rich and diverse biotic areas which have been produced by methods like genetic engineering and species introduction. Reasons for this are considered. A-areas are artefacts: their existence has been intentionally brought about by intentionally modifying their properties in order to produce an entity (...) of their type. Nevertheless, since some restored ecosystems are equally artifacts and still valued over A-areas in biodiversity management, artifactuality cannot alone explain the low value of the A-areas. The essential difference between A-areas and restored ecosystems is in naturalness of their properties. By contrast with the properties of A-areas, the properties of any restored ecosystem are similar to the properties of some ecosystems that have originated through evolutionary processes. I conclude that biodiversity management decisions are based on multiple and different conceptions of natural, unnatural and artificial. The most desired alternatives are natural in all senses of the terms. Because of limits set by the real world, conservation biologists sometimes have to settle for second best alternatives that are unnatural in some sense of the term, but not in all or many of them.

The desire to use established corporate law skill sets in the pro bono context has lead some lawyers to extend pro bono services to charitable and non-profit organisations. But does the provision of free legal services to well-funded organisations constitute pro bono work, and how can providers of pro bono legal services best prioritise among competing organisations? The author surveys various sources of formal and informal regulation in Singapore and selected Asian and other common law jurisdictions and suggests that when (...) distinguishing between non-profit organisations with different levels of funding, a coherent guideline would evaluate whether the payment of legal fees would deplete economic resources to the extent of significantly impairing organisation programmes.

In this paper, semi-Post algebras are introduced and investigated. The generalized Post algebras are subcases of semi-Post algebras. The so called primitive Post constants constitute an arbitrary partially ordered set, not necessarily connected as in the case of the generalized Post algebras examined in [3]. By this generalization, semi-Post products can be defined. It is also shown that the class of all semi-Post algebras is closed under these products and that every semi-Post algebra is a semi-Post product of some generalized (...) Post algebras. (shrink)
