Enactive and ecological approaches to cognitive science both claim a “mutuality” between agents and their environments – that they have a complementary nature and should be addressed as a single whole system. Despite this apparent agreement, each offers criticisms of the other on precisely this point – enactivists claiming that ecological psychologists over-emphasise the environment, while the complementary criticism, of agent-centred constructivism, is levelled by ecological psychologists at enactivists. In this paper I suggest that underlying the confusion between the two (...) approaches is the complexity of agency, which comes in different forms, at different scales or levels of analysis. Cognitive science has not theorised the relationship between these different forms in a sufficiently disciplined manner, and a task therefore remains of finding a way to map the complex territory of agency.

Perceptual modalities have been traditionally considered the product of dedicated biological systems producing information for higher cognitive processing. Psychological and neuropsychological evidence is offered which undermines this point of view and an alternative account of modality from the enactive approach to understanding cognition is suggested. Under this view, a perceptual modality is a stable form of perception which is structured not just by the biological sensitivities of the agent, but by their goals and the set of skills or expertise which (...) they are deploying at a given time. Such a view suggests that there is no such thing as an experience that is purely visual, auditory, or otherwise modal and that our attempts to understand consciousness and the mind must be conducted within a framework that provides an account of embodied, goal-directed adaptive coping with the world.

The world of Jedi is very different from our own, that their awareness of the universe is more encompassing, richer. The Jedi call that mystical aspect of reality they perceive the Force. Jedi younglings and padawans must put their body to new uses, perform new tasks, and learn new skills in physical activities that have profound effects on the way they see the world around them. What the Jedi say more than anything else about the Force is that it flows. (...) Jedi who are able to coordinate their actions with that flow can work with the full potency of the universal relationship between all things. Jedi do not need a special Force‐organ to perceive the Force. The Force is not something Jedi just see, or hear, or taste, or touch, but rather it is something they experience on its own terms, probably using their whole body to do it. (shrink)

The document titled “14 points of Wilson” was announced by the President of the United States Woodrow Wilson in his speech addressed to the United States Congress on 8th January 1918. The speech is one of the most well known documents of the First World War as it touched upon several world issues. The text has been interpreted ever since in respect to the importance and real meaning of points formulated by Wilson. One of the points referred to Poland. The (...) aim of the paper is to focus on the exponents of deontic modality used in that text of historical value and to find the answer to the question concerning the deontic value of each point. The analysis will encompass the principles of deontic logic as well as the meaning of deontic modals in legal discourse at the time of speech delivery as those 14 points should be classified as a text belonging to legal genres. The aim of the paper is to present the historical background and the linguistic analysis in order to find out whether historical facts, interpretations and language used correspond with one another.

Can we see the expressiveness of other people's gestures, hear the intentions in their voice, see the emotions in their posture? Traditional theories of social cognition still say we cannot because intentions and emotions for them are hidden away inside and we do not have direct access to them. Enactive theories still have no idea because they have so far mainly focused on perception of our physical world. We surmise, however, that the latter hold promise since, in trying to understand (...) cognition, enactive theory focuses on the embodied engagements of a cognizer with his world. In this paper, we attempt an answer for the question What is social perception in an enactive account? In enaction, perception is conceived as a skill, crucially involving action, an ability to work successfully within the set of regularities, or contingencies that characterize a given domain. If this is the case, then social perception should be a social skill. Having thus transformed the question of what social perception is into that of what social skill is, we examine the concept of social contingencies and the manner in which social skills structure—both constrain and empower— social interaction. Some of the implications of our account for how social and physical perception differ, the role of embodiment in social interaction and the distinction between our approach and other social contingency theories are also addressed.

The enactive approach to cognitive science involves frequent references to “action” without making clear what is intended by the term. In particular, though autopoiesis is seen as a foundation for teleology in the enactive literature, no definition or account is offered of goals which can encompass not just descriptions of biological maintenance, but the range of social and cultural activities in which human beings continually engage. The present paper draws primarily on the work of Juarrero (Dynamics in action. Cambridge, MA: (...) MIT Press, 1999) and Donald (Origins of the modern mind. London: Wiedenfeld & Nicolson, 1991) in an attempt to offer the broad outlines of an account of goals and goal-directedness which is consistent with the enactive approach and which explicates several forms of goal-directedness exhibited by human beings. Four stages of cognitive evolution described by Donald are examined for characteristic mechanisms of adaptivity and goal-directedness. Implications for an enactive theory of meaning are discussed.

Die Intentionalität des Psychischen charakterisiert Meinong als Erfassen eines Gegenstandes durch das erfassende Erlebnis, wobei der erfaßte Gegenstand weder zu existieren noch zu bestehen braucht. Ein Gegenstand ist geradezu bestimmt als das, was erfaßt werden kann; der erfaßte Gegenstand ist aber nicht Teil des erfassenden Erlebnisses. Gleichsam als subjektives, psychisches Korrelat stellt Meinong dem erfaßten Gegenstand (Objekt, Objektiv etc.) den entsprechenden Erlebnisinhalt (Vorstellungsinhalt, Urteils- bzw. Annahmeinhalt etc.) gegenüber, der zu dem betreffenden Gegenstand in einer Adäquatheitsrelation steht. Ziel des Aufsatzes ist (...) es, einige der Schwierigkeiten zu besprechen, die die Einführung von derartigen psychischen Inhalten mit sich bringen. M.E. gibt es keinen brauchbaren Anhaltspunkt, herauszufinden, wie die psychischen Inhalte ihre Aufgabe, auf die Gegenstände zu referieren, sie dem Erfassen darzubieten, zu erfüllen vermögen. Weitere schwerwiegende Probleme ergeben sich aus der Frage, welche Gegenstände hinweisendem Denken entsprechen und wie es gelingen kann, durch einen Hilfsgegenstand den Zielgegenstand zu erfassen.

It is generally assumed that the brain causes conscious experience. A broad view of this kind can be termed neuronal reductionism. It is universally regarded that neuronal reductionism is founded on a solid empirical basis. However, it is possible to show that none of the arguments usually advanced to support its contentions are conclusive. Moreover, there are a number of serious empirical as well conceptual difficulties that this view has to face, and to which it has not responded in a (...) satisfactory way so far. Taking these challenges in their entirety it seems justified to claim that neuronal reductionism is a failed theory and that the search for an answer to the question about the origin of consciousness has to take a novel turn.

The boundary between spiritual experience and mental disorder remains unclear and should invite collaboration between psychiatry and other disciplines, including theology. Jackson and Fulford (1997), using the tools of analytic philosophy, have proposed a model allowing principled differentiation between spiritual experience and psychotic symptoms based on the personal values of the subject, a cognitive problem-solving model. Spiritual experience is described as positively evaluated psychotic experience, which enables the subject to do more than he or she normally does. In the present (...) paper, it is claimed that values and actions cannot alone always discriminate between religious experience and psychopathology. With reference to three case studies, drawn from the practice of one of us, it is argued that spirituality is not all about experience and that it cannot be understood without reference to the subject's personal history and spiritual tradition, however implicit or fragmented. This approach would allow an account of ordinary religious experience in those who have suffered ego disablement during mental illness. Drawing primarily on the Christian tradition, we argue that the use of theological criteria may allow levels of discrimination between spiritual experience and mental disorder not allowed for by philosophical psychopathology.

Akt, a protein kinase hyperactivated in many tumors, plays a major role in both cell survival and resistance to tumor therapy. A recent study,1 along with other evidences, shows interestingly, that Akt is not a single‐function kinase, but may facilitate rather than inhibit cell death under certain conditions. This hitherto undetected function of Akt is accomplished by its ability to increase reactive oxygen species and to suppress antioxidant enzymes. The ability of Akt to down‐regulate antioxidant defenses uncovers a novel Achilles' (...) heel, which could be exploited by oxidant therapies in order to selectively eradicate tumor cells that express high levels of Akt activity.

The paper deals with several problems concerning with notion of truth. The author is interested in logical aspects of the definition of truth given by Ajdukiewicz and Kotarbinski. He introduces the multimodal logical calculus with propositional quantifier and applies it to analysis of some formulations of the definition. The analysis is focused on two main formulations of the definition, namely on absolute and partial formulation. It is shown that the notion of truth specified by absolute formulation is unconstructive i.e. it (...) is possible to state that some utterance is true without stating any sentence which express the propositional content of the utterance. On the other hand after the partial formulation the notion of truth seems to have some counterintuitive features, for example the falsehood is no longer the same as the lack of truth. Moreover only the absolute approach leads to difficulties connected with the Liar Paradox. (shrink)

A number of nonmonotonic reasoning formalisms have been introduced to model the set of beliefs of an agent. These include the extensions of a default logic, the stable models of a general logic program, and the extensions of a truth maintenance system among others. In [13] and [16], the authors introduced nonmonotomic rule systems as a nonlogical generalization of all essential features of such formulisms so that theorems applying to all could be proven once and for all. In this paper, (...) we extend Rieter's normal default theories, which have a number of the nice properties which make them a desirable context for belief revision, to the setting of nonmonotonic rule systems. Reiter defined a default theory to be normal if all the rules of the default theory satisfied a simple syntatic condition. However, this simple syntatic condition has no obvious analogue in the setting of nonmonotonic rule systems. Nevertheless, an analysis of the proofs of the main results on normal default theories reveals that the proofs do not rely on the particular syntactic form of the rules but rather on the fact that all rules have a certain consistency property. This led us to extend the notion of normal default theories with respect to a general consistency property. This extended notion of normal default theories, which we call Forward Chaining normal , is easily lifted to nonmonotomic rule systems and hence applies to general logic programs and truth maintenance.
