This is a book that no one but Weyl could have written--and, indeed, no one has written anything quite like it since.

Decision-making capacity (DMC) is the gatekeeping element for a patient’s right to self-determination with regard to medical decisions. A DMC evaluation is not only conducted on descriptive grounds but is an inherently normative task including ethical reasoning. Therefore, it is dependent to a considerable extent on the values held by the clinicians involved in the DMC evaluation. Dealing with the question of how to reasonably support clinicians in arriving at a DMC judgment, a new tool is presented that fundamentally differs (...) from existing ones: the U-Doc. By putting greater emphasis on the judgmental process rather than on the measurement of mental abilities, the clinician as a decision-maker is brought into focus, rendering the tool more of an evaluation guide than a test instrument. In a qualitative study, the perceived benefits of and difficulties with the tool have been explored. The findings show on the one hand that the evaluation aid provides basic orientation, supports a holistic perspective on the patient, sensitizes for ethical considerations and personal biases, and helps to think through the decision, to argue, and to justify one’s judgment. On the other hand, the room for interpretation due to absent operationalisations, related ambiguities, and the confrontation with one’s own subjectivity may be experienced as unsettling. (shrink)

ver since the traditional criteria for medical decision-making capacity (understanding, appreciation, reasoning, evidencing a choice) were formulated, they have been criticized for not taking sufficient account of emotions or values that seem, according to the critics and in line with clinical experiences, essential to decision-making capacity. The aim of this paper is to provide a nuanced and structured overview of the arguments provided in the literature emphasizing the importance of these factors and arguing for their inclusion in competence evaluations. Moreover, (...) a broader reflection on the findings of the literature is provided. Specific difficulties of formulating and measuring emotional and valuational factors are discussed inviting reflection on the possibility of handling relevant factors in a more flexible, case-specific, and context-specific way rather than adhering to a rigid set of operationalized criteria.

A new study of the mathematical-physical mode of cognition.

Diem takes issue with the misuse of Kierkegaard's work in present-day theological and philosophical discussion. This is a translations of Die Existenzdialektik von Soren Kierkegaard.

Recent advances in neuroscience lead to a wider realm for philosophy to include the science of the Darwinian-evolved computational brain, our inner world producing organ, a non-recursive super- Turing machine combining 100B synapsing-neuron DNA-computers based on the genetic code. The whole system is a logos machine offering a world map for global context, essential for our intentional grasp of opportunities. We start from the observable contrast between the chaotic universe vs. our orderly inner world, the noumenal cosmos. So far, philosophy (...) has been rehearsing our thoughts, our human-internal world, a grand painting of the outer world, how we comprehend subjectively our experience, worked up by the logos machine, but now we seek a wider horizon, how humans understand the world thanks to Darwinian evolution to adapt in response to the metaphysical gap, the chasm between the human animal and its environment, shaping the organism so it can deal with its variable world. This new horizon embraces global context coded in neural structures that support the noumenal cosmos, our inner mental world, for us as denizens of the outer environment. Kant’s inner and outer senses are fundamental ingredients of scientific philosophy. Several sections devoted to Heidegger, his lizard debunked, but his version of the metaphysical gap & his doctrine of the logos praised. Rorty and others of the behaviorist school discussed also.

Impressions, energy radiated by phenomena in the momentary environmental scene, enter sensory neurons, creating in afferent nerves a data stream. Following Kant, by our inner sense the mind perceives its own thoughts as it ties together sense data into an internalized scene. The mind, residing in the brain, logically a Language Machine, processes and stores items as coded grammatical entities. Kantian synthetic unity in the linguistic brain is able to deliver our experience of the scene as we appear to see (...) it. Uniquely, the brain records its own history, synthesizing a Movie-in-the-Brain, called the Noumenal Cosmos. Attempting thereby to represent the actual Universe, this makes for a sovereign brain that governs itself. The brain is domicile of an Ego, with its selfhood at stake at all times. Yet, it can know itself only by its actions, in which it appears as an actor in its own movie. Phenomena enter garbled, as confused apparitions, and must be put in good form using top–down feedback control by Ego, so that each movie frame makes rational sense within the overall context of the Noumenal Cosmos. A stack of frames is processed typically in 40 Hz rhythm with 300 ms process time each, for about 12 in the stack at any time. Successive neural centers are processing the stack in the brain assembly line, based on data from increasingly global receptive fields. Ego stitches together the movie frames, but only the top frame is in consciousness for 25 ms. The top frame contains the whole scene where the Ego makes an appearance as the actor that imposes Kantian synthetic unity on the scene, merely an assembly of grammatical texts, in a system-internal coded process language, fitting the scene into the Noumenal Cosmos. But Ego observes Ego only to the extent permitted by the objectivity rule, only what it does and thinks, not its true face. From the Noumenal Cosmos, the Ego receives grammatical messages in the internal sense code. They are integrated into a whole in the reaction of the Ego to the momentary scene. The voluntary nature of Ego’s decisions is explained, based on its ability to code in advance its own actions sequentially in time, as it sees fit with a view to an orderly Noumenal Cosmos, records of code being arranged spatially in neural structures.

ZusammenfassungDie Bestimmung der Einwilligungsfähigkeit von Patienten beinhaltet weitreichende ethische und rechtliche Implikationen. Ausreichende Klärung des Begriffs ist daher unerlässlich. Solche Bemühungen gelten vorwiegend der Definition von Kriterien hinsichtlich relevanter mentaler Fähigkeiten. Grundlegendere Aspekte werden kaum explizit besprochen, so die Frage, ob Einwilligungsfähigkeit eher eine inhärente Fähigkeit oder ein ethisches Urteil bezeichnet. Zentral bei dieser Unterscheidung ist der Stellenwert ethischer Überlegungen die Zulässigkeit fürsorglicher Bevormundung betreffend. Geht man von einer inhärenten Fähigkeit aus, schließen solche Überlegungen an die Beurteilung von Einwilligungsfähigkeit an. (...) Im Fall eines Urteils sind diese konstitutiv für das Verständnis und die Bestimmung von Einwilligungsfähigkeit. Obwohl Einwilligungsfähigkeit idealerweise als inhärente Fähigkeit gedacht wird, weist die tatsächliche Herangehensweise eher in die Richtung, sie als ethisches Urteil zu verstehen. Diese verschiedenen Tendenzen sind für konzeptuelle Kontroversen hinsichtlich des Stellenwerts risiko-relativer Beurteilungen verantwortlich. Des Weiteren muss sich die Bestimmung von Einwilligungsfähigkeit – konzipiert man sie als ethisches Urteil – nicht rigide an einer bestimmten Definition des Begriffs der Autonomiefähigkeit orientieren und vermag so mit dessen definitorischen Unklarheiten besser umzugehen.

Both the title of this treatise and its traditional placement as the second of Aristotle's logical writings are highly misleading. What, on the one hand, De Interpretatione deals with is not, as its title suggests, a theory of interpretation, but rather a theory of statement-making sentences of different sorts and the logical relations that obtain between them; and what, on the other hand, this theory aims at is not, as suggested by the place which De Interpretatione traditionally occupies in the (...) Organon between the Categories and the Prior Analytics, providing preliminaries to the study of syllogistic by analyzing statement-making sentences as possible parts of syllogisms, but rather underpinning the study of dialectical debates by examining such sentences as possible members of contradictory pairs. Among other things, De Interpretatione deals with symbols or signs, truth, bivalence, determinism, modal logic, and modal statements. (shrink)

In this theoretical study we explore the concept of intentional-ity. Intentionality is the specific reference that mental phenomena have with respect to objects, also termed the 'aboutness' of cognitive acts. We discuss intentionality on the basis of self-organized pattern formation, a ubiquitous phenomenon in complex open systems. Dynamical systems theory provides an understanding of how emergent variables originate from microscopic variables. Control parameters comprise those external parameters and gradients that drive the systems they represent environmental inuences. The relationship between pattern (...) formation and control parameters therefore addresses the functioning of a system in its environment. Our hypothesis is that self-organizing systems exhibit intentionality-like capabilities in their responses to environmental inuences. This is modelled using differential calculus, by which we demonstrate how pattern formation reduces control parameters in an efficient manner. These ideas are applied to the complex system brain, using the Wilson-Cowan equations of axonal pulse rates in neural networks. (shrink)

Objective: While behavioral recommendations regarding physical activity commonly focus on reaching demanding goals by proposing ‘thresholds’, little attention has been paid to the question of how much of a behavioral change is needed to make people feel that they have changed. The present research investigated this relation between actual and felt behavior change. Design: Using data from two longitudinal community samples, Study 1 and 2 comprised 614 (63 % women) and 398 participants (61 % women) with a mean age of (...) 40.9 years (SD = 13.6) and 42.5 years (SD = 13.4), respectively. Using a stage-approach, participants were classified into four groups by asking them at the respective second measurement to indicate whether they had become more physically active since their last participation six months ago (“Changers”), had tried but did not succeed in becoming more physically active (“Attempters”), were already physically active on a regular basis (“Regular Actives”), or had not tried to become more physically active (“Non-Attempters”). Physical activity was measured using the International Physical Activity Questionnaire (IPAQ), and fitness level was assessed as physical working capacity (PWC) via bicycle ergometry. Mixed ANOVAs including Time and Perceived Change as within and between factors were conducted, followed up by simple effect analyses. Results: Participants stating to have become more active in the past six months (Changers) showed a significant increase in vigorous physical activity but not in moderate physical activity, with an average of 6.8 (Study 1) and 10.6 (Study 2) MET-h per week in vigorous activity. Corroborating these findings, objective fitness also significantly increased in the group of Changers. No systematic change in moderate or vigorous physical activity was observed for the three other ‘non-changer’ groups (regular actives, attempters, non-attempters). Conclusion: The intensity of physical activity is the crucial variable for people’s perception of change in physical activity. Moderate physical activity seems not to be perceived as an effective means for behavior change. It thus might fail to unfold sufficient motivational impact, despite its known positive effects on health. (shrink)

The present article is devoted to the second part of chapter 10 of Aristotle’s De interpretatione (20 a 16-40), which mainly deals with the logical relations between statements whose predicate is finite (i. e., of the affirmative form “is P”) and statements whose predicate is infinite (i. e., of the negative form “is not-P”). I attempt to show that this part of the chapter contains both a section the text of which is corrupt (20 a 20-23) and a section which (...) is misplaced (20 a 37-40). In the former section the likely false reading of the manuscripts τῇ δὲ … ἡ ἀντι- κειμένη ὅτι … (“while from ‘…’ the opposite [statement follows] that …”) should be corrected into ἡ δὲ … τῇ ἀντικειμένῃ ὅτι … (“while ‘…’ [follows] from the opposite [statement] that …”), and the latter section should be placed immediately after the former, with which it is intimately connected.

Georg Cantor's absolute infinity, the paradoxical Burali-Forti class Ω of all ordinals, is a monstrous non-entity for which being called a "class" is an undeserved dignity. This must be the ultimate vexation for mathematical philosophers who hold on to some residual sense of realism in set theory. By careful use of Ω, we can rescue Georg Cantor's 1899 "proof" sketch of the Well-Ordering Theorem––being generous, considering his declining health. We take the contrapositive of Cantor's suggestion and add Zermelo's choice function. (...) This results in a concise and uncomplicated proof of the Well-Ordering Theorem. (shrink)

We present a game semantics in the style of Lorenzen for Girard's linear logic . Lorenzen suggested that the meaning of a proposition should be specified by telling how to conduct a debate between a proponent P who asserts and an opponent O who denies . Thus propositions are interpreted as games, connectives as operations on games, and validity as existence of a winning strategy for P. We propose that the connectives of linear logic can be naturally interpreted as the (...) operations on games introduced for entirely different purposes by Blass . We show that affine logic, i.e., linear logic plus the rule of weakening, is sound for this interpretation. We also obtain a completeness theorem for the additive fragment of affine logic, but we show that completeness fails for the multiplicative fragment. On the other hand, for the multiplicative fragment, we obtain a simple characterization of game-semantical validity in terms of classical tautologies. An analysis of the failure of completeness for the multiplicative fragment leads to the conclusion that the game interpretation of the connective is weaker than the interpretation implicit in Girard's proof rules; we discuss the differences between the two interpretations and their relative advantages and disadvantages. Finally, we discuss how Gödel's Dialectica interpretation , which was connected to linear logic by de Paiva , fits with game semantics. (shrink)

Studie se zabývá tím, jak se v českých zemích obráželo bouřlivé období vývoje biologického myšlení od přelomu 19. a 20. století do první světové války, kdy vedle sebe existovaly velmi různé názory na evoluci. Mnohovrstevnatost teoretickou přitom doplňuje i kulturní a vědecká mnohovrstevnatost českých zemí, kde se jednak mísí vlivy německé a české biologie na svých autonomních institucích, a jednak lze spatřovat rozdíly i mezi lokálními centry Prahou a Brnem se svými badatelskými tradicemi a nezávislými vazbami na další centra ve (...) Vídni a evropských univerzitách. Centrem zájmu jsou teoreticky uvažující biologové, kteří buď sami dlouhodobě profilovali české biologické myšlení, anebo na něj měli díky zdejšímu působení přímý vliv. V letech ca 1900–1915 došlo k prvnímu otevřenému a diskutovanému vrcholu v české recepci evolucionismu a před jednoznačnými pozicemi a „velkými teoriemi“ má navrch spíše prostředkování diferencované zahraniční diskuse, podněty vlastní experimentální práce a opatrné očekávání od nového studia variability a dědičnosti.

Usually one reads that after the foundation of scientific journals the journal article took the place of scientific correspondence. It is shown here that periodicals did not replace the letter, but only supplemented it. Norms were developed for the journal article such that (in short) only the „context of justification”︁, not the „context of discovery”︁, could be discussed. Any scholar who wanted to participate in the „discussion out of which science arises”︁ had to resort to the letter; the reading of (...) journals did not suffice. — This circumstance is illustrated in particular by the example of quantum theory and by Wolfgang Pauli.
