This essay attempts to develop a psychologically informed semantics of perception reports, whose predictions match with the linguistic data. As suggested by the quotation from Miller and Johnson-Laird, we take a hallmark of perception to be its fallible nature; the resulting semantics thus necessarily differs from situation semantics. On the psychological side, our main inspiration is Marr's (1982) theory of vision, which can easily accomodate fallible perception. In Marr's theory, vision is a multi-layered process. The different layers have filters of (...) different gradation, which makes vision at each of them approximate. On the logical side, our task is therefore twofold • to formalise the layers and the ways in which they may refine each other, and • to develop logical means to let description vary with such degrees of refinement. The first task is formalised by means of an inverse systems of first order models, with reality appearing as its inverse limit. The second task is formalised by means of so-called conditional quantifiers, a new form of generalised quantification which can best be described as resource bounded quantification. We show that the logic provides for a semantics and pragmatics of direct perception reports. In particular, direct perception reports have a possibly nonveridical, approximative semantics, which becomes veridical only by virtue of our pragmatic expectation that what is perceived would continue to be the case, were we to perceive more accurately. It is a general feature of resource bounded logics that the underlying logics are weak, but that stronger principles can be obtained pragmatically, by strengthening the resource. For the logic of vision this feature is clarified by showing how changes in the resource capture different notions of partiality, and by studying how the perception verb interacts with connectives and quantifiers in different visual contexts. The inference Veridicality, which is now viewed rather as a nonmonotonic inference, is also studied in depth. We end with an attempt to buttress the proposed model by comparing it with suggestions put forward in Cognitive or Conceptual Semantics, in the literature on evidentials, and in Husserl's philosophy of perception.

Synthetic biology is an emerging technology that asks for inclusive reflection on how people frame the field. To unravel how we can facilitate such reflection, this study evaluates the Frame Reflection Lab. Building upon playfulness design principles, the FRL comprises a workshop with video-narratives and co-creative group exercises. We studied how the FRL facilitated frame reflection by organizing workshops with various student groups. Analysis of 12 group conversations and 158 mini-exit surveys yielded patterns in first-order reflection as well as patterns (...) in second-order reflection. Also patterns in participants’ framing of synthetic biology could be induced; participants’ viewpoints converged to some extent, yet with openness to individual viewpoint differences. Although the FRL method fortified the reflection processes of participants, the narratives and the workshop’s flexible format could inhibit the reflection too. Therefore, we advise designers of future frame reflection methods to apply stronger conversational facilitation and narratives of slightly mysterious yet identifiable narrators, in case e.g. video-narratives are created and used to scaffold the reflection process. Nevertheless, we argue that the use of a playful frame reflection method like the FRL could function well as a step to precede more application-specific deliberation or decision-making on synthetic biology and as a method for the collection of contemporary citizen viewpoints plus rationales underlying these, for the further responsible development of the emerging field.

Finding meaning in our lives is a central tenet to the human experience and a core contributor to mental health. Individuals tend to actively seek the sources of meaning in their lives or consciously enact efforts to create or “craft” meaning in different life domains. These overall “Life Crafting” behaviors refer to the conscious efforts individuals exert to create meaning in their lives through cognitively framing how they view life, seeking social support systems to manage life challenges, and actively seeking (...) challenges to facilitate personal growth. Specifically, these behaviors are actioned to better align life goals, personal needs, values, and capabilities. However, no psychological assessment instrument currently exists to measure overall life crafting. As such, the purpose of this paper was twofold: to conceptualize life crafting and to develop, validate and evaluate a robust measure of overall life crafting. A mixed-method, multi-study research design was employed. First, nine participants were interviewed to determine the methods or techniques used to craft meaningful life experiences. These methods/techniques were used as indicators to create an initial item pool which was then reviewed by a panel of experts to ensure face validity. Second, in Study 1, the factorial structure of the instrument was explored by gathering data from a convenience sample, with the results showing support for a three-factor structure of life crafting, consisting of cognitive crafting, seeking social support, and seeking challenges. Finally, in Study 2, the aim was to confirm the factorial structure of the Life Crafting scale and to determine its level of internal consistency, partial measurement invariance across genders, and criterion validity [meaning in life, mental health, work engagement, and job burnout ]. The results supported a second-order factorial model of Life Crafting, which comprised of three first-order factors. Therefore, the Life Crafting Scale can be used as a valid and reliable instrument to measure- and track the effectiveness of life crafting interventions. (shrink)

In academic research, many attempts have been undertaken to legitimize corporate community involvement by showing a business case for it. However, much less attention has been devoted to building understanding about the actual dynamics and challenges of managing CCI in the business context. As an alternative to existing predominantly static and top-down approaches, this paper introduces a social movement framework for analyzing CCI management. Based on the analysis of qualitative case study data, we argue that the active role of employees (...) pressuring for CCI policies and practices, as well as the organization audience responses to their efforts, are at the core of the challenges involved in managing CCI. These challenges also pose limits to how far CCI can be extended to a “business as usual” activity. (shrink)

This paper is on the update semantics for might of Veltman. Threeconsequence relations are introduced and studied in an abstract setting.Next we present sequent-style systems for each of the consequence relations.We show the logics to be complete and decidable.

This article draws on the results of an inductive qualitative study on the microdynamics of framing corporate community involvement. Insight is provided into these dynamics by using the metaphor of a social movement and drawing on that literature’s framing perspective. Based on accounts of diverse organizational members, we identify several double edges in framing CCI as a strategic issue, and we develop a model that helps to understand why and how strategizing CCI may be controversial.

The article argues for a contextualised reading of Wittgenstein’s Tractatus. It analyses in detail the role that use and application play in the text and how that supports a conception of transcendentality of logic that allows for contextualisation. The article identifies a tension in the text, between the requirement that sense be determinate and the contextual nature of application, and suggests that it is this tension that is a major driver of Wittgenstein’s later ideas.

This study investigated the relationship between the development of students? self-regulated learning and students? perceptions of the learning environment in terms of autonomy support, the emphasis on relevance and collaborative learning. In addition, we compared innovative learning environments that aim to enhance self-regulated learning with traditional learning environments. Questionnaires for measuring self-regulated learning and perceptions of the learning environment were administered by 648 students. Self-regulated learning was measured at the start of secondary education and again half way through the first (...) year. The results point to the importance of how students perceive the learning environment for self-regulated learning. There was a positive relationship between autonomy support and relevance and self-regulated learning. Furthermore, students in innovative environments perceived more autonomy support, more emphasis on relevance and more collaborative learning than those in traditional environments. Students in innovative environments, however, reported no more self-regulated learning than students in traditional environments. (shrink)

This note is on cautious cut elimination for one of Veitman's might logics. Syntactically, the logic is presented as an extension of a sequent system for classical proposition logic . I show that this extension preserves the completeness and decidability of CPL. The proof has cautious cut elimination as a corollary. I also give a rather general syntactic proof of cautious cut elimination. It states that any ‘base’ logic which has a reflexive, monotone consequence relation that allows cautious cut to (...) be eliminated preserves cautious cut elimination when extended to a might logic.

During the past three decades the Utrecht scholar Jaap Mansfeld has built up a formidable reputation in the field of the history of ancient philosophy. This state-of-the-art collection of articles is presented to him by colleagues and friends on his sixtieth birthday.

Modern technology (Technik, la technique) has constituted the gears on which the wheels of the modern world keep turning. The later Heidegger devotes sustained reflection to this unprecedented phenomenon in human history. It is notable that, compared with other figures from twentieth-century continental philosophy, Heidegger has served as the most frequent reference point in current philosophy of technology (Technikphilosophie). This field of philosophy came into being after the so-called empirical turn of “Science and Technology Studies.” While relevant scholars focus mainly (...) on “Die Frage nach der Technik” of 1953, “Das Ge-stell” of 1949,1 and some other texts written in that period,2 the time span of Heidegger’s ..

The article explores the relationship between Baukunst and Zeitwille in the practice and pedagogy of Ludwig Mies van der Rohe, and the significance of the notions of civilization and culture for his philosophy of education and design practice. Focusing on the negation of metropolitan life and mise en scene of architectural space as its starting point, it examines how Georg Simmel’s notion of objectivity could be related to Mies’s understanding of civilization. Its key insight is to recognize that Mie’s practice (...) and pedagogy was directed by the idea that architecture should capture the driving force of civilization. The paper also summarizes the foundational concepts of Mies’s curriculum in Chicago. It aims to highlight the importance of the notions of Zeitwille and impersonality in Mies van der Rohe’s thought and to tease apart the tension between the impersonality and the role of the autonomous individual during the modernist era.

The book aims to develop a new approach to philosophy of medicine. Much attention is paid to the relative merits of philosophical analysis in the Anglo-Saxon tradition, and phenomenology. Themes considered are cultural bias in philosophy of medicine, regular versus alternative medicine, concepts of health and disease, and the mind-body problem.

John Rawls wrote that people can voluntarily acquire political obligations to institutions only on the condition that those institutions are at least reasonably just. When an institution is seriously unjust, by contrast, attempts to create political obligation are “void ab initio.” However, Rawls's own explanation for this thought was deeply problematic, as are the standard alternatives. In this paper, I offer an argument for why Rawls's intuition was right and trace its implications for theories of authority and political obligation. These, (...) I claim, are more radical than is often thought. (shrink)

In Anarchy, State, and Utopia, Robert Nozick contrasts entitlement theories of justice and “traditional” theories such as Rawls', utilitarianism or egalitarianism, and advocates the former against the latter. What exactly is an entitlement theory of justice? Nozick's book offers two distinct characterizations. On the one hand, he explicitly describes “the general outlines of the entitlement theory” as maintaining “that the holdings of a person are just if he is entitled to them by the principles of justice in acquisition and transfer, (...) or by the principle of rectification of injustice ”. On the other hand, his famous “Wilt Chamberlain” argument against alternative theories is first said to apply to “non-entitlement conceptions”, and later to any “end-state principle or distributional patterned principle of justice” — which amounts to an implicit characterization of an entitlement conception as a conception of justice which is neither end-state nor patterned.

Ideals are important in social reality, but they have been neglected in theories of law, politics, and morality. This book has the role of ideals as its central theme. More specifically, it argues that ideals are necessary to understand pluralism, that they are key elements in controversy and debate, and that they enable development. It combines theoretical analysis of the concept of ideals with discussion of concrete debates and cases, including philosophical debates about politics and equality, sociological studies of the (...) diverse interpretations of the rule of law, and accounts of the development of environmental law and privacy law. Thus, the functioning of ideals is critically examined, showing the merits and limitations of an ideal-oriented approach. (shrink)
