Umberto Eco argues that a mirror image is not a sign. At best it is a double, a thing that ceases to be once the reflected object is removed. Harry Mulisch narratively suggests that mirror images function metaphorically as gateways between human suffering and the divine. And interestingly, science employs mirrors and mirror images both to turn our gaze upwards and to show us reflections of our place in the cosmos. Tying together Eco's notion of the double, (...) class='Hi'>Mulisch's insistence that mirror images reflect humanity's construction of the divine, and the Giant Magellan Telescope Project's cosmic images, it is my contention that modern, telescopic mirror images are much more than snapshots of the cosmos. They are constructions of human and divine meaning that—signifying—pose the question, what is reflected: the cosmos or humanity? (shrink)

'Mass terms', words like water, rice and traffic, have proved very difficult to accommodate in any theory of meaning since, unlike count nouns such as house or dog, they cannot be viewed as part of a logical set and differ in their grammatical properties. In this study, motivated by the need to design a computer program for understanding natural language utterances incorporating mass terms, Harry Bunt provides a thorough analysis of the problem and offers an original and detailed solution. (...) An extension of classical set theory, Ensemble Theory, is defined, and this provides the conceptual basis of a framework for the analysis of natural language meaning which Dr Bunt calls Two-level model-theoretic semantics. The validity of the framework is convincingly demonstrated by the formal analysis of a fragment of English including sentences with quantified and modified mass terms. Separate chapters of the book are devoted to an axiomatic definition of Ensemble Theory and a detailed discussion of its status as a mathematical formalism. (shrink)

This article addresses the critical comments that focus on what is perceived as lack of clarity with regard to different uses of the system concept: on the one hand, in the usual general sense, on the other, in a specific ‘Habermassian’ sense. This final reply tries to remedy this in critical discussion with Morin, arguing that Morin’s paradigm of generalized complexity addresses the question of what subjects are, but remains silent with regard to the question of who they are. Answering (...) this question confronts us with a specific ethical manifestation of complexity that cannot be adequately understood within the conceptual space of systems-oriented complexity theory.

This paper argues that the substance concept, as discussed by Aristotle in his Categories, aids us to improve our understanding of human nature. Aristotle distinguished the primary from the secondary substance, and substantial from accidental change. We explain these distinctions, their use for understanding phenomena, and discuss how we can integrate them with evolutionary explanations of human nature. For explaining of how the typical human characteristics evolved, we extend our investigations with a discussion of the concept of person. It is (...) argued that psychological attributes, used to characterize persons, are not attributes of a separate mental substance, as Cartesians believe. The concept of a person, though not a substance concept, qualifies a substance concept of a human being possessing rational powers. The latter evolved as the result of language evolution. (shrink)

This Is A New Release Of The Original 1920 Edition.

The Gestalt psychologist Kurt Lewin called for a “psychological ecology” that would bring to light the social structures serving as the context for individual action and choice in everyday life. He envisioned social and physical environmental structures affecting the individual at a “boundary” within psychological experience. But how are we to conceptualize the manner in which such environmental structures influence individual experience and action? After all, the “nonpsychological” and the psychological domains are typically framed in quite different conceptual language, and, (...) in some cases, at different levels of analysis. This paper examines this question with respect to two bodies of work. In the case of perception, Fritz Heider’s pioneering analysis of perception, followed decades later by James Gibson’s ecological approach to perception, illuminated the significance of a medium for perceiving that conveys structure specific to environmental entities. As for action among community structures, Roger Barker’s research revealed the significance of the hierarchical structure of the environment of community life, and how some higher-order structures can influence and constrain individual constituent actions nested within them. Recent treatment of the psychological boundary within the 4E cognition literature is also briefly and critically examined. (shrink)

In his article ‘Better Communication Between Engineers and Managers: Some Ways to Prevent Many Ethically Hard Choices’1 Michael Davis analyzes the causes of the disaster in terms of a communications gap between management and engineers. When the communication between (representatives of) both groups breaks down, the organization is in (moral) trouble. Crucial information gets stuck somewhere in the organization prohibiting a careful discussion and weighing of all (moral) arguments. The resulting judgment has therefore little (moral) quality. In this paper I (...) would like to comment on some of Michael Davis’s interesting and thought-provoking insights and ideas. A company which implements Davis’s recommendations at least shows some sensitivity to organizational moral issues. But it might miss the point that moral trouble can also result from a common understanding between managers and engineers. Organizational members sometimes tend to be myopic with regard to safety issues. This paper: 1. describes different meanings of safety Managers and engineers, as Davis mentions, are sometimes willing to compromise quality, but do sacrifice safety. It is my contention that safety—in the sense of putting people’s lives on the line—will always be compromised, and that the discussion is about the ways to negotiate the risks./li 2. focuses on a shared understanding of the situation and its implications for safety Using examples from a case study I did on behalf of a commercial airline,2 I will try to show that it is not always the communications gap between managers and engineers which poses a risk to the stakeholders involved, but a common understanding of the situation. 3. focuses on a ‘timely concatenation of both active and latent failures’ as a cause for accidents I will argue that—in spite of our efforts to strengthen ethical consciousness and organizational practices—there will always be accidents. They are part of the human condition, since we cannot completely control the complexity of the situations in which they occur. One can, however, make them less costly. (shrink)

The use of a reporter gene in transgenic mice indicates that there are many local mutations and large genomic rearrangements per somatic cell that accumulate with age at different rates per organ and without visible effects. Dissociation of the cells for monolayer culture brings out great heterogeneity of size and loss of function among cells that presumably reflect genetic and epigenetic differences among the cells, but are masked in organized tissue. The regulatory power of a mass of contiguous normal cells (...) is expressed in its capacity to normalize the appearance and growth behavior of solitary homophilic neoplastic cells, and to redirect differentiation of solitary heterophilic stem‐like cells. Intimate contact between the interacting cells is required to induce these changes. The normalization of the neoplastic phenotype does not require gap junctional communication between cells, though transdifferentiation might. These varied relationships are manifestations of the unifying biological principle of “order in the large over heterogeneity in the small”. BioEssays 28: 515–524, 2006. © 2006 Wiley Periodicals, Inc.

Erstmals im deutschsprachigen Raum werden in diesem repräsentativen Reader Arbeiten von Harry G. Frankfurt publiziert, dessen Überlegungen bedeutsam wurden für nicht-utilitaristische Werttheorien, für die Ethik der Fürsorge bzw. der Tugendethik, aber auch für die moderne Rationalitätstheorie. Freiheit und Determinismus sind miteinander vereinbar - diese Auffassung vertritt Frankfurt nachdrücklich. Zunächst entwickelte er ein hierarchisches Modell des Wünschens und arbeitete eine philosophische Begründung für das Argument aus, daß die Bedingung, jemand hätte anders handeln können, keine notwendige Bedingung für Freiheit und Verantwortung (...) bildet. In seinen neuesten Arbeiten entwirft er ein umfassenderes Konzept der Selbstbestimmung und der Rationalität, wobei er sein früheres Wunschmodell ersetzt durch ein erweitertes hierarchisches Modell fundamentaler Einstellungen, zu denen neben Wünschen nunmehr auch Überzeugungen und Emotionen zählen, die sich daher zugleich auf Konzeptionen unseres Charakters und unserer Integrität richten.

Maung argues that an externalist understanding of mental disorder exposes how, if society was more just for the most deprived, patterns of access to assisted dying might be different. I counter that reducing inequality lacks relevance to the immediate permissibility of assisted dying for mental disorder, owing to the need for solutions for those in distress. I suggest that the question of assistance in death for mental disorders is one of pragmatic politics, not for obfuscatory philosophy.
