We define an applicative theory of truth TPTTPT which proves totality exactly for the polynomial time computable functions. TPTTPT has natural and simple axioms since nearly all its truth axioms are standard for truth theories over an applicative framework. The only exception is the axiom dealing with the word predicate. The truth predicate can only reflect elementhood in the words for terms that have smaller length than a given word. This makes it possible to achieve the very low proof-theoretic strength. (...) Truth induction can be allowed without any constraints. For these reasons the system TPTTPT has the high expressive power one expects from truth theories. It allows embeddings of feasible systems of explicit mathematics and bounded arithmetic.The proof that the theory TPTTPT is feasible is not easy. It is not possible to apply a standard realisation approach. For this reason we develop a new realisation approach whose realisation functions work on directed acyclic graphs. In this way, we can express and manipulate realisation information more efficiently. (shrink)

BackgroundBiobanking biospecimens and consent are common practice in paediatric research. We need to explore children and young people’s (CYP) knowledge and perspectives around the use of and consent to biobanking. This will ensure meaningful informed consent can be obtained and improve current consent procedures.MethodsWe designed a survey, in co-production with CYP, collecting demographic data, views on biobanking, and consent using three scenarios: 1) prospective consent, 2) deferred consent, and 3) reconsent and assent at age of capacity. The survey was disseminated (...) via the Young Person’s Advisory Group North England (YPAGne) and participating CYP’s secondary schools. Data were analysed using a qualitative thematic approach by three independent reviewers (including CYP) to identify common themes. Data triangulation occurred independently by a fourth reviewer.ResultsOne hundred two CYP completed the survey. Most were between 16–18 years (63.7%, N = 65) and female (66.7%, N = 68). 72.3% had no prior knowledge of biobanking (N = 73).Acceptability of prospective consent for biobanking was high (91.2%, N = 93) with common themes: ‘altruism’, ‘potential benefits outweigh individual risk’, 'frugality', and ‘(in)convenience’.Deferred consent was also deemed acceptable in the large majority (84.3%, N = 86), with common themes: ‘altruism’, ‘body integrity’ and ‘sample frugality’. 76.5% preferred to reconsent when cognitively mature enough to give assent (N = 78), even if parental consent was previously in place. 79.2% wanted to be informed if their biobanked biospecimen is reused (N = 80).ConclusionProspective and deferred consent acceptability for biobanking is high among CYP in the UK. Altruism, frugality, body integrity, and privacy are the most important themes. Clear communication and justification are paramount to obtain consent. Any CYP with capacity should be part of the consenting procedure, if possible. (shrink)

'Everyone knows what attention is’ according to William James. Much work on attention in psychology and neuroscience cites this famous phrase only to quickly dismiss it. But James is right about this: ‘attention’ was not introduced into psychology and neuroscience as a theoretical concept. I argue that we should therefore study attention with broadly the same methodology that David Marr has applied to the study of perception. By focusing more on Marr's Computational Level of analysis, we arrive at a unified (...) answer to the question of what attention is, what role it plays in the mind, and why organisms like us have that capacity. I propose a methodology for studying attention at Marr's Computational Level that optimizes in a three-dimensional space: it should capture core aspects of our first-person experience of attention, be explanatorily powerful in psychology and neuroscience, and fertile in an interdisciplinary context. I show how this methodology leads to what I call the priority structure account of attention. Attention is what organizes current information to make it more useful for the organism. We can identify it by four features. Attention, in this way, helps a cognitive system to integrate its informational state with its current motivational state. I describe how this account improves on alternatives and shows why attention is a useful concept in many disciplines and for connecting them. -/- This article is categorized under: Philosophy > Psychological Capacities Psychology > Attention Philosophy > Foundations of Cognitive Science.

The normative force of evidence can seem puzzling. It seems that having conclusive evidence for a proposition does not, by itself, make it true that one ought to believe the proposition. But spelling out the condition that evidence must meet in order to provide us with genuine normative reasons for belief seems to lead us into a dilemma: the condition either fails to explain the normative significance of epistemic reasons or it renders the content of epistemic norms practical. The first (...) aim of this paper is to spell out this challenge for the normativity of evidence. I argue that the challenge rests on a plausible assumption about the conceptual connection between normative reasons and blameworthiness. The second aim of the paper is to show how we can meet the challenge by spelling out a concept of epistemic blameworthiness. Drawing on recent accounts of doxastic responsibility and epistemic blame, I suggest that the normativity of evidence is revealed in our practice of suspending epistemic trust in response to impaired epistemic relationships. Recognizing suspension of trust as a form of epistemic blame allows us to make sense of a purely epistemic kind of normativity the existence of which has recently been called into doubt by certain versions of pragmatism and instrumentalism.

In dieser Untersuchung wird die Instandhaltung technischer Artefakte, neben deren Schaffung und Nutzung die dritte grundlegende Form technischen Handelns, als Teilthema der Technikphilosophie systematisch und umfassend analysiert. Nur durch Instandhaltung können die unermeßlichen und vielfältigen mittels technischer Verfahren erzeugten Werte vor vorzeitigem Verfall und Untergang bewahrt werden. Die Studie erschließt Instandhaltung in phänomenologischer (Grundlagen) und normativer Hinsicht (Instandhaltung und Gesellschaft). Die auf Unumkehrbarkeit des Handelns und ganz allgemein des Geschehens gegründete Endlichkeit seiner Dauer bindet das individuelle technische Artefakt als wesentliches (...) Element in den Verlauf der Allgemein-, Technik-, Kultur-, Wirtschafts- und Sozialgeschichte ein. (shrink)

It is often argued that there are no practical reasons for belief because we could not believe for such reasons. A recent reply by pragmatists is that we can often believe for practical reasons because we can often cause our beliefs for practical reasons. This paper reveals the limits of this recently popular strategy for defending pragmatism, and thereby reshapes the dialectical options for pragmatism. I argue that the strategy presupposes that reasons for being in non-intentional states are not reducible (...) to reasons to act. Pragmatists who want to preserve a motivational constraint on reasons therefore have exactly two options: either arguing that there are irreducible reasons for being in non-intentional states ; or arguing that we can believe directly for practical reasons. I argue that the prospects for the former option are dim because irreducible reasons to be in states are hard to square with the motivational constraint on reasons. Returning to the more traditional route of arguing for pragmatism by defending a version of doxastic voluntarism therefore seems to be the more promising way for pragmatists to go. (shrink)

What is attention? How does attention shape consciousness? In an approach that engages with foundational topics in the philosophy of mind, the theory of action, psychology, and the neurosciences this book provides a unified and comprehensive answer to both questions. Sebastian Watzl shows that attention is a central structural feature of the mind. The first half of the book provides an account of the nature of attention. Attention is prioritizing, it consists in regulating priority structures. Attention is not another (...) element of the mind, but constituted by structures that organize, integrate, and coordinate the parts of our mind. Attention thus integrates the perceptual and intellectual, the cognitive and motivational, and the epistemic and practical. The second half of the book concerns the relationship between attention and consciousness. Watzl argues that attentional structure shapes consciousness into what is central and what is peripheral. The center-periphery structure of consciousness cannot be reduced to the structure of how the world appears to the subject. What it is like for us thus goes beyond the way the world appears to us. On this basis, a new view of consciousness is offered. In each conscious experience we actively take a stance on the world we appear to encounter. It is in this sense that our conscious experience is our subjective perspective. (shrink)

A trusted guide into the inner realm where our spirits find strength to master life and live for God. It is hard to exaggerate the significance of Innerland, either for Eberhard Arnold or his readers. It absorbed his energies off and on for most of his adult life--from World War I, when he published the first chapter under the title War: A Call to Inwardness, to 1935, the last year of his life. Packed in metal boxes and buried at (...) night for safekeeping from the Nazis, who raided the author_s study a year before his death (and again a year after it), Innerland was not openly critical of Hitler_s regime. Nevertheless, it attacked the spirits that animated German society: its murderous strains of racism and bigotry, its heady nationalistic fervor, its mindless mass hysteria, and its vulgar materialism. In this sense Innerland stands as starkly opposed to the zeitgeist of our own day as to that of the author_s. At a glance, the focus of Innerland seems to be the cultivation of the spiritual life as an end in itself. Nothing could be more misleading. In fact, to Eberhard Arnold the very thought of encouraging the sort of selfish solitude whereby people seek their own private peace by shutting out the noise and rush of public life around them is anathema. He writes in The Inner Life:_These are times of distress. We cannot retreat, willfully blind to the overwhelming urgency of the tasks pressing on society. We cannot look for inner detachment in an inner and outer isolation...The only justification for withdrawing into the inner self to escape today's confusing, hectic whirl would be that fruitfulness is enriched by it. It is a question of gaining within, through unity with eternal powers, a strength of character ready to be tested in the stream of the world._ Innerland, then, calls us not to passivity, but to action. It invites us to discover the abundance of a life lived for God. It opens our eyes to the possibilities of that _inner land of the invisible where our spirit can find the roots of its strength and thus enable us to press on to the mastery of life we are called to by God._ Only there, says Eberhard Arnold, can our life be placed under the illuminating light of the eternal and seen for what it is. Only there will we find the clarity of vision we need to win the daily battle that is life, and the inner anchor without which we will lose our moorings. (shrink)

Conceptual engineering is the enterprise of evaluating and improving our representational devices. But how should we conduct this enterprise? One increasingly popular answer to this question proposes that conceptual engineering should proceed in terms of the functions of our representational devices. In this paper, we argue that the best way of understanding this suggestion is in terms of normative functions, where normative functions of concepts are, roughly, things that they allow us to do that matter normatively (for example, things in (...) virtue of which we have normative reasons to have these concepts). Not only does this introduce a novel view about functions to the literature. This proposal also fits more naturally than the alternatives with conceptual engineering as a normative enterprise, and it allows functions to play all of the explanatory roles assigned to them in the conceptual engineering literature. Our discussion of the explanatory advantages of normative functions also advances the understanding of the ways in which concepts can be authoritative, what this means for conceptual engineering, and highlights the importance of political philosophy for thinking about conceptual engineering in practice. Furthermore, the paper explicates what kind of role considerations about function can and should actually play in conceptual engineering. (shrink)

The three ancient philosophical introductions translated in this volume flesh out our picture of what it would have been like to sit in a first-year Philosophy course in ancient Alexandria. Ammonius (AD 445-517/26) set up a new teaching programme in Alexandria with up to six introductions to the philosophy curriculum, which made it far more accessible, and encouraged its spread from Greek to other cultures. This volume's three introductory texts include one by his student Olympiodorus and one each by Olympiodorus' (...) students Elias and David. Elias' Introductions to Philosophy starts with six definitions of Philosophy, to which David adds replies to the sceptical question whether there is such a thing as Philosophy. Olympiodorus' text translated here is an Introduction to Logic, which is just one of the three introductions he wrote himself. (shrink)

The development of artificial intelligence (AI) in medicine raises fundamental ethical issues. As one example, AI systems in the field of mental health successfully detect signs of mental disorders, such as depression, by using data from social media. These AI depression detectors (AIDDs) identify users who are at risk of depression prior to any contact with the healthcare system. The article focuses on the ethical implications of AIDDs regarding affected users’ health-related autonomy. Firstly, it presents the (ethical) discussion of AI (...) in medicine and, specifically, in mental health. Secondly, two models of AIDDs using social media data and different usage scenarios are introduced. Thirdly, the concept of patient autonomy, according to Beauchamp and Childress, is critically discussed. Since this concept does not encompass the specific challenges linked with the digital context of AIDDs in social media sufficiently, the current analysis suggests, finally, an extended concept of health-related digital autonomy.

Many of our attitudes are non-culpable: there was nothing that we should have done to avoid holding them. I argue that we can still be blameworthy for non-culpable attitudes: they can impair our relationships in ways that make our full practice of apology and forgiveness intelligible. My argument poses a new challenge to indirect voluntarists, who attempt to reduce all responsibility for attitudes to responsibility for prior actions and omissions. Rationalists, who instead explain attitudinal responsibility by appeal to reasons-responsiveness, can (...) make sense of blameworthiness for non-culpable attitudes. In response, voluntarists could propose a revision of our actual practices. This would lead us into a quite different debate. (shrink)

La cessation hebdomadaire du travail le dimanche est de plus en plus contestée dans notre société. Si les exigences économiques rendent nécessaire le fonctionnement ininterrompu des machines, il faudrait assurer à chaque employé un autre jour de repos. Peut-on alors définir le dimanche comme jour de repos commun à la majorité de la société ? Les chrétiens ont l’habitude de se prononcer en faveur du repos dominical en rappelant le commandement du Décalogue : «Observe le jour du sabbat ». Or (...) cet argument n’est pas pertinent pour des raisons historiques et herméneutiques. Il est toutefois possible de tirer de ce commandement, en particulier de sa version deutéronomique (Dt 5,12-15), des arguments susceptibles d’enrichir les débats d’aujourd’hui. (shrink)
