RESUMO Ainda que Tomás de Aquino não usasse o termo intencionalidade frequentemente, ele tem uma teoria que explica como nós, enquanto sujeitos, nos referimos intencionalmente aos objetos. Nossa referência funciona quando há uma "identidade formal" entre a forma no ato de percepção ou conhecimento do sujeito e a forma do objeto. Na literatura secundária, "identidade formal" é muitas vezes o nome usado para chamar essa teoria. Nosso artigo visa o fato de que, em Tomás, a tese da identidade formal não (...) é só epistemológica, mas ela exige uma base metafísico-ontológica. O resultado da nossa investigação é que, segundo a tese da identidade formal, a referência epistêmica aos objetos funciona de maneira direta, mas por meio disso ela não produz uma variedade de objetos imanentes ou intencionais na ontologia. ABSTRACT Even if Thomas Aquinas did not use the term intentionality often, He has a theory that explains how we, as subjects, intentionally refer to objects. Our reference works when there is a "formal identity" between the form in the act of perception or subject knowledge and the form of the object. In secondary literature, "formal identity" is the name used to refer to that theory. Our article aims at the fact that, in Thomas's writings, the formal identity thesis is not only epistemological, but requires a metaphysical-ontological basis. The result of our investigation is that, according to the formal identity thesis, the epistemic reference to objects works on a direct way, but by means of that it does not produce a variety of immanent or intentional objects within ontology.

The distinction between actus humanus and actus hominis is the best-known distinction in Thomas Aquinas’ theory of action. A human action (actus humanus) is a special case of an act of a human being (actus hominis). Several acts of our intellect and will form a human action and thereby put it from the realm of pure natural happenings (genus naturae) into the moral realm (genus moris). The paper at hand shows the character and main parameters of Thomas Aquinas’ action theory, (...) especially in the Summa theologiae I-II, quaestiones 6-17. Moreover, it presents Thomas Aquinas’ central idea of what is the essence of a human action. The analysis especially makes use of the element of command (imperium) It shows that, according to Aquinas, acting consists in the intellectually comprehensible self-disclosure of a person and therefore builds the basis for the moral evaluation of human actions.

The integration of ethics into the day-to-day work of research and innovation is an important but difficult challenge. However, with the Aachen method for identification, classification and risk analysis of innovation-based problems an approach from an engineering perspective is presented that enables the integration of ethical, legal and social implications into the day-to-day work of R&I practitioners. AMICAI appears in particular capable of providing a procedural guidance for R&I practitioners based on a method established in engineering science, breaking down the (...) object of consideration into partial aspects and prioritizing the innovation-based problems in dependence of potential risk. This enables the user to apply AMICAI continuously during all stages of the research and development process and to analyze and choose between certain sociotechnical alternatives. In this way, problems that affect ethical, legal, and social aspects can be understood, reflected and considered in the mostly technically focused R&D process. The paper gives a general guidance about AMICAI by describing principles and assumptions, providing the steps of analysis and application aids, giving an example application, explaining the necessary adjustments of AMICAI compared to the methodical basis of failure mode, effects, and criticality analysis and discussing the advantages and limits. AMICAI’s simple applications can stimulate interdisciplinary cooperation in the R&D process and be a starting point for the development of an “open RRI risk analysis platform” allowing society to evaluate innovation-based problems.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Achieving space domain awareness requires the identification, characterization, and tracking of space objects. Storing and leveraging associated space object data for purposes such as hostile threat assessment, object identification, and collision prediction and avoidance present further challenges. Space objects are characterized according to a variety of parameters including their identifiers, design specifications, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, processes, operational statuses, and associated persons, organizations, or nations. The Space Object Ontology provides a consensus-based realist framework (...) for formulating such characterizations in a computable fashion. Space object data are aligned with classes and relations in the Space Object Ontology and stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space domain awareness and the needs of spacecraft operators. This paper presents the core of the Space Object Ontology, discusses its advantages over other approaches to space object classification, and demonstrates its ability to combine diverse sets of data from multiple sources within an expandable framework. Finally, we show how the ontology provides benefits for enhancing and maintaining longterm space domain awareness. (shrink)

Background: Smart sensors have been developed as diagnostic tools for rehabilitation to cover an increasing number of geriatric patients. They promise to enable an objective assessment of complex movement patterns. -/- Objective: This research aimed to identify and analyze the conflicting ethical values associated with smart sensors in geriatric rehabilitation and provide ethical guidance on the best use of smart sensors to all stakeholders, including technology developers, health professionals, patients, and health authorities. -/- Methods: On the basis of a systematic (...) literature search of the scientific databases PubMed and ScienceDirect, we conducted a qualitative document analysis to identify evidence-based practical implications of ethical relevance. We included 33 articles in the analysis. The practical implications were extracted inductively. Finally, we carried out an ethical analysis based on the 4 principles of biomedical ethics: autonomy, beneficence, nonmaleficence, and justice. The results are reported in categories based on these 4 principles. -/- Results: We identified 8 conflicting aims for using smart sensors. Gains in autonomy come at the cost of patient privacy. Smart sensors at home increase the independence of patients but may reduce social interactions. Independent measurements performed by patients may result in lower diagnostic accuracy. Although smart sensors could provide cost-effective and high-quality diagnostics for most patients, minorities could end up with suboptimal treatment owing to their underrepresentation in training data and studies. This could lead to algorithmic biases that would not be recognized by medical professionals when treating patients. -/- Conclusions: The application of smart sensors has the potential to improve the rehabilitation of geriatric patients in several ways. It is important that patients do not have to choose between autonomy and privacy and are well informed about the insights that can be gained from the data. Smart sensors should support and not replace interactions with medical professionals. Patients and medical professionals should be educated about the correct application and the limitations of smart sensors. Smart sensors should include an adequate representation of minorities in their training data and should be covered by health insurance to guarantee fair access. (shrink)

"These notes are about the process of design: the process of inventing things which display new physical order, organization, form, in response to function." This book, opening with these words, presents an entirely new theory of the process of design. In the first part of the book, Christopher Alexander discusses the process by which a form is adapted to the context of human needs and demands that has called it into being. He shows that such an adaptive process (...) will be successful only if it proceeds piecemeal instead of all at once. It is for this reason that forms from traditional un-self-conscious cultures, molded not by designers but by the slow pattern of changes within tradition, are so beautifully organized and adapted. When the designer, in our own self-conscious culture, is called on to create a form that is adapted to its context he is unsuccessful, because the preconceived categories out of which he builds his picture of the problem do not correspond to the inherent components of the problem, and therefore lead only to the arbitrariness, willfulness, and lack of understanding which plague the design of modern buildings and modern cities. In the second part, Mr. Alexander presents a method by which the designer may bring his full creative imagination into play, and yet avoid the traps of irrelevant preconception. He shows that, whenever a problem is stated, it is possible to ignore existing concepts and to create new concepts, out of the structure of the problem itself, which do correspond correctly to what he calls the subsystems of the adaptive process. By treating each of these subsystems as a separate subproblem, the designer can translate the new concepts into form. The form, because of the process, will be well-adapted to its context, non-arbitrary, and correct. The mathematics underlying this method, based mainly on set theory, is fully developed in a long appendix. Another appendix demonstrates the application of the method to the design of an Indian village. (shrink)

Several current theories have essences as primary drivers of inductive potential: e.g., people infer dogs share properties because they share essences. We investigated the possibility that people take occupational roles as having robust inductive potential because of a different source: their position in stable social institutions. In Studies 1–4, participants learned a novel property about a target, and then decided whether two new individuals had the property (one with the same occupation, one without). Participants used occupational roles to robustly generalize (...) rights and obligations, functional behaviors, personality traits, and skills. In Studies 5–6, we contrasted occupational roles (via label) with race/gender (via visual face cues). Participants reliably favored occupational roles over race/gender for generalizing rights and obligations, functional behaviors, personality traits, and skills (they favored race/gender for inferring leisure behaviors and physiological properties). Occupational roles supported inferences to the same extent as animal categories (Studies 4 and 6). In Study 7, we examined why members of occupational roles share properties. Participants did not attribute the inductive potential of occupational roles to essences, they attributed it to social institutions. In combination, these seven studies demonstrate that any theory of inductive potential must pluralistically allow for both essences and social institutions to form the basis of inductive potential.

This article examines two questions about scientists’ search for knowledge. First, which search strategies generate discoveries effectively? Second, is it advantageous to diversify search strategies? We argue pace Weisberg and Muldoon, “Epistemic Landscapes and the Division of Cognitive Labor”, that, on the first question, a search strategy that deliberately seeks novel research approaches need not be optimal. On the second question, we argue they have not shown epistemic reasons exist for the division of cognitive labor, identifying the errors that led (...) to their conclusions. Furthermore, we generalize the epistemic landscape model, showing that one should be skeptical about the benefits of social learning in epistemically complex environments. (shrink)

Überwindet Technik das unheimlich Unbeherrschbare? Oder wird sie uns selbst unheimlich? Zwei scheinbar widersprüchliche Narrative prägen die Geschichte und auch die Theorie der Technik: Das Narrativ der Entzauberung beschreibt, wie eine als fremd und gefährlich erfahrene Natur durch Verwissenschaftlichung und Technisierung gezähmt wurde. Das Narrativ der Verzauberung schildert, wie uns Artefakte und technologische Möglichkeiten unheimlich werden, insbesondere wenn sie sich zu verselbständigen scheinen oder mit „autonomem“ Eigensinn gegenübertreten. In den heutigen Debatten um selbstlernende, ubiquitär verteilte, im Assistenzmodus unsichtbare, dabei opake (...) Techniken schwingt das unheimliche Moment einer „Verselbständigung“ von Technik mit – und trägt im Anschluss an die Mechanisierungs- und Automatisierungsdiskurse des 20. Jahrhunderts zur „Dämonisierung“ der Technik bei. Technik macht Welt einerseits vertraut und nachvollziehbar: Paradigmatisch wird dies in der Idee, dass etwas dann verstanden wird, wenn es technisch rekonstruiert werden kann. Andererseits wird die technische Reproduktion von Welt – oder deren radikale Umgestaltung zu einer entfremdeten – als etwas Verstörendes erlebt. Spätestens, wenn Artefakte zu tun scheinen, „was sie wollen“ oder technische Großsysteme die Lebenswelt nach ihren „Eigenlogiken“ prägen, ist eine schon von Freud benannte Grenze erreicht, an der wir verunsichert werden, ob wir überhaupt noch in der modernen Welt leben.

The rapid diffusion of artificial intelligence (AI) technologies in the defence domain raises challenges for the ethical governance of these systems. A recent shift from the what to the how of AI ethics sees a nascent body of literature published by defence organisations focussed on guidance to implement AI ethics principles. These efforts have neglected a crucial intermediate step between principles and guidance concerning the elicitation of ethical requirements for specifying the guidance. In this article, we outline the key normative (...) choices and corresponding tradeoffs that are involved in specifying guidance for the implementation of AI ethics principles in the defence domain. These correspond to: the AI lifecycle model used; the scope of stakeholder involvement; the accountability goals chosen; the choice of auditing requirements; and the choice of mechanisms for transparency and traceability. We provide initial recommendations for navigating these tradeoffs and highlight the importance of a pro-ethical institutional culture. (shrink)

Suggests that acknowledging that social inquiry may be indelibly linked to ethical reflection raises difficult questions . There seem to be a few fundamental metatheoretical options available, each presuming some ontology of human existence and colored by at least a few basic moral or spiritual commitments. The options are briefly sketched, and their virtues and blind spots highlighted. The options include mainstream social science, "descriptivisms," liberal individualism, existential freedom, and contemporary hermeneutics. It is suggested that a hermeneutic view of social (...) theory as practice offers an alternative to both explanatory and constructionist accounts. 2012 APA, all rights reserved). (shrink)

Thomas Aquinas situates virtues of character in the noncognitive appetite. He also claims that virtues of character provide the ends in practical matters. Since providing proper ends seems to be a cognitive act, it is unclear how virtues of character, qua perfections of the noncognitive appetite, provide ends. After criticizing three approaches to this interpretive challenge, we suggest that Aquinas provides us with a theory of practical identity. We argue that that on Aquinas's view a practical identity is constituted both (...) by a virtuous disposition in the appetitive power and by a rational commitment to proximate ends, a rational commitment that results from acquiring the virtuous disposition. With this account of practical identity in mind, we explain how Aquinas can consistently claim that virtues, qua perfections of the appetite, provide ends. (shrink)

The German Act on Autonomous Driving constitutes the first national framework on level four autonomous vehicles and has received attention from policy makers, AI ethics scholars and legal experts in autonomous driving. Owing to Germany’s role as a global hub for car manufacturing, the following paper sheds light on the act’s position within the ethical discourse and how it reconfigures the balance between legislation and ethical frameworks. Specifically, in this paper, we highlight areas that need to be more worked out (...) in the future either through ethical conventions, corporate measures or legal measures and examine how the law can be incorporated into the existing discourse on the regulation of technologies. Based on this examination, we derive implications for future discourse and elaborate on companies’ responsibilities in developing autonomous driving technologies in an ethical sense. (shrink)

This article provides a methodology for the interpretation of AI ethics principles to specify ethical criteria for the development and deployment of AI systems in high-risk domains. The methodology consists of a three-step process deployed by an independent, multi-stakeholder ethics board to: (1) identify the appropriate level of abstraction for modelling the AI lifecycle; (2) interpret prescribed principles to extract specific requirements to be met at each step of the AI lifecycle; and (3) define the criteria to inform purpose- and (...) context-specific balancing of the principles. The methodology presented in this article is designed to be agile, adaptable, and replicable, and when used as part of a pro-ethical institutional culture, will help to foster the ethical design, development, and deployment of AI systems. The application of the methodology is illustrated through reference to the UK Ministry of Defence AI ethics principles. (shrink)

Contemporary architecture is increasingly grounded in science and mathematics. Architectural discourse has shifted radically from the sometimes disorienting Derridean deconstruction, to engaging scientific terms such as fractals, chaos, complexity, nonlinearity, and evolving systems. That's where the architectural action is -- at least for cutting-edge architects and thinkers -- and every practicing architect and student needs to become conversant with these terms and know what they mean. Unfortunately, the vast majority of architecture faculty are unprepared to explain them to students, not (...) having had a scientific education themselves. Here is an architecture book by an architect/scientist, just in time to help architects in the new millennium. Alexander discusses many of the scientific terms arising in cutting-edge architecture, and explains them to those who don't have scientific training or advanced mathematical knowledge. We find discussions of the evolution of forms; the importance of process in design; iteration; genetic algorithms; sequences of transformations; different levels of scale (i.e. fractals); etc. They are explained here by an architect who is also a scientist, because he wants to change the way architects think and build. Alexander is not merely popularizing other scientists' results and making them accessible to architects: he is in fact presenting new and original scientific work that ties many of these concepts together in a way that will be useful to architects.

We investigate dependence of recursively enumerable graphs on the equality relation given by a specific r.e. equivalence relation on ω. In particular we compare r.e. equivalence relations in terms of graphs they permit to represent. This defines partially ordered sets that depend on classes of graphs under consideration. We investigate some algebraic properties of these partially ordered sets. For instance, we show that some of these partial ordered sets possess atoms, minimal and maximal elements. We also fully describe the isomorphism (...) types of some of these partial orders. (shrink)

This article represents a concerted Laszlo effort. What you will find here is a collection of autobiographical reflections written by Ervin Laszlo that speaks to his involvement with the field of systems thinking and his impact on it, interspersed with comments and illustrative examples on points of special interest. As such, this essay should be read as a reflection piece?one in which a new generation of Laszlos muse on the power and inspiration of the vision that has served as a (...) platform not only for them but for many others in the systems community as well. To understand Ervin Laszlo and his contributions to the systems view of the world, one must place him in context?both ontologically and epistemologically. This narrative will do both, first presenting a chronological overview of his personal history up to the present and subsequently exploring the world of ideas and ideals that he traversed (and continues to traverse with unrelenting momentum). However, this narrative will inevitably be nonlinear, and bits and pieces of his adventure in thought are woven into his chronological development and vice-versa. (shrink)

Spiel und Arbeit gelten oft als Gegensätze: Das Spiel als freie Betätigung menschlicher Vermögen, die Arbeit als deren Subordination unter einen äußeren Zweck. Die Festlegung des Spiels auf konsequenzlose Wiederholbarkeit hat ihm den Ruf des Unernsten eingetragen, während das Abzwecken der Arbeit auf die Nützlichkeit ihres Resultats im Bund mit der Sorge ums Dasein steht. Auf einen zweiten Blick scheint dieser Gegensatz jedoch, gerade in den hochentwickeltsten Ausprägungen beider Tätigkeitsformen, zu verschwinden. So kann eine hochgradige Rationalisierung von Spielpraktiken in Arbeit (...) umschlagen, wie etwa im Leistungssport, oder ein komplexer Arbeitsvorgang selbstzweckhafte Momente und Eigendynamiken gewinnen, die ihm Spielcharakter verleihen. Auch andere technologische Entwicklungen geben Anlass dazu, das Verhältnis von Spiel und Arbeit noch einmal grundsätzlich zu bedenken, etwa im Hinblick auf: adaptive Systeme in der Robotik, serious games, Kreativitätstechniken in Unternehmenskulturen, wissenschaftliche Experimentalanordnungen, Online-Rollenspiele oder die Kommodifizierung nicht-zweckrationaler Lebensvollzüge, die traditionell vom Begriff produktiver Arbeit ausgeschlossen waren – einschließlich der Spielräume, die durch neue Umwelt- und Biotechniken erschlossen werden. Die Beschaffenheit der jeweils zum Einsatz kommenden Mittel und Verfahren sowie die Setzung, Variation oder Preisgabe von Zwecken können den Charakter von Spiel und Arbeit sowie ihr Verhältnis zueinander bestimmen oder verändern.

Unter der Leitdifferenz „Steuern – Regeln“ werden in der herkömmlichen Technikphilosophie die beiden Operationsmodi „klassischer“ Technik gefasst und beschrieben. Dies geschieht in zweierlei Hinsicht: zum einen in der Absicht, die sich seit der neolithischen Revolution ausprägende menschliche Technik im Unterschied zur „Zufallstechnik“ höherer Spezies oder der Urmenschen zu spezifizieren; zum anderen mit dem Ziel, das Verhältnis von Technik und Wissenschaft genauer freizulegen. Indessen fordern aktuelle Technologien, historische Zustandsbeschreibungen einer „Technoscience“ sowie neue epistemische Praktiken die Zweiteilung von „Steuern“ und „Regeln“ heraus. (...) Mit Blick auf sogenannte „new emerging sciences and technologies“ und andere Entwicklungen in den Informations-, Kognitions-, Nano- und Biotechnologien fragt dieser Band danach, wer oder was als Subjekt von Steuerungs- und Regelungsprozessen konzeptualisiert werden kann. Im Kontext großtechnischer Systeme sowie der Organisation großer sozialer Gebilde werden die Steuerungsmöglichkeiten dabei zunehmend problematisch, denn insbesondere digitale Informationstechnologien eröffnen neue, vielfältige Optionen zur Manipulation und Regulation von Prozessen oder Zuständen, während gegenläufige Konsequenzen derselben Entwicklung die Möglichkeiten einer koordinierten Steuerung zunehmend in Frage stellen.

Das Nichtwissen ist in aller Munde. Von Nichtwissenskulturen in der zweiten oder reflexiven Moderne ist die Rede, von Agnotologie als neuem Forschungszweig, von wicked problems und ihren clumsy solutions. Wo Nichtwissen sich durch Komplexitäts­steigerung unwiderruflich im zu Wissenden einnistet, fordert es als Grenze, Schranke und Kehrseite des Wissens die sogenannte Wissensgesellschaft heraus. Vor allem Risiko­poten­ziale und Gefahren kommen hier in den Blick, von denen wir gerade genug wissen, um Wissensansprüche zu formulieren, die sich womöglich nie einlösen lassen. Das klassisch erkenntnistheoretische (...) Problem: „Was können wir wissen?“ steht heute in einem Spannungsverhältnis zu der wissenspolitischen Frage: „Was müssen wir wissen?“ Was wir wissen müssen, ist einerseits so viel wie nötig, wenn es um Fragen von Sicherheit und Gesundheit geht – andererseits aber so wenig wie möglich, wenn es in Alltag, Wirtschaft oder Wissen­schaft darauf ankommt, Wissen an technische Systeme oder Expertenkulturen zu delegieren. Bezeichnet politisch handlungsorientiertes und wissenschaftliches Nichtwissen zunächst ein Defizit, ist technisches Nichtwissen gleichermaßen erstrebenswert und problematisch. Einige, die Technik für angewandtes Wissen halten, mögen darin eine contradictio in adjecto sehen, manche sich um eine dem technischen Nichtwissen geschuldeten Technik­feindlichkeit sorgen, andere daraus die nötige Demut gegen verstiegene Allmachts­fantasien beziehen, während ihre Gegenspieler von Maschinen träumen, die über den Horizont intellektueller Nachvollziehbarkeit immer weiter hinauseilen.

The venerable cities of the past, such as Venice or Amsterdam, convey a feeling of wholeness, an organic unity that surfaces in every detail, large and small, in restaurants, shops, public gardens, even in balconies and ornaments. But this sense of wholeness is lacking in modern urban design, with architects absorbed in problems of individual structures, and city planners preoccupied with local ordinances, it is almost impossible to achieve. In this groundbreaking volume, architect and planner Christopher Alexander presents (...) a new theory of urban design which attempts to recapture the process by which cities develop organically. To discover the kinds of laws needed to create a growing whole in a city, Alexander proposes here a preliminary set of seven rules which embody the process at a practical level and which are consistent with the day-to-day demands of urban development. He then puts these rules to the test, setting out with a number of his graduate students to simulate the urban redesign of a high-density part of San Francisco, initiating a project that encompassed some ninety different design problems, including warehouses, hotels, fishing piers, a music hall, and a public square. This extensive experiment is documented project by project, with detailed discussion of how each project satisfied the seven rules, accompanied by floorplans, elevations, street grids, axonometric diagrams and photographs of the scaled-down model which clearly illustrate the discussion. A New Theory of Urban Design provides an entirely new theoretical framework for the discussion of urban problems, one that goes far to remedy the defects which cities have today. (shrink)

We respond to Conor McHugh's claim that an evaluative account of the normative relation between belief and truth is preferable to a prescriptive account. We claim that his arguments fail to establish this. We then draw a more general sceptical conclusion: we take our arguments to put pressure on any attempt to show that an evaluative account will fare better than a prescriptive account. We briefly express scepticism about whether McHugh's more recent ‘fitting attitude’ account fares better.
