Back in 1987 the physicist/theoretical biologist Walter Elsasser reviewed a range of philosophical issues at the foundation of organismal biology above the molecular level. Two of these are particularly relevant to quantifications of form: the concept of ordered heterogeneity and the principle of nonstructural memory, the truism that typically the forms of organisms substantially resemble the forms of their ancestors. This essay attempts to weave Elsasser’s principles together with morphometrics for one prominent data type, the representation of animal forms by (...) positions of landmark points. I introduce a new spectrum of pattern descriptors of the shape variation of landmark configurations, ranging from the most homogeneous through growth gradients and focal features to a model of totally disordered heterogeneity incompatible with the rhetoric of functional explanation. An investigation may end up reporting its findings by one of these descriptors or by several. These descriptors all derive from one shared diagrammatic device: a log–log plot of sample variance against one standard formalism of today’s geometric morphometrics, the bending energies of the principal warps that represent all the scales of variability around the sample average shape. The new descriptors, which I demonstrate over a variety of contemporary morphometric examples, may help build the bridge we urgently need between the arithmetic of today’s burgeoning image-based data resources and the rhetoric of biological explanations aligned with the principles of Elsasser along with an even earlier philosopher of biology, the Viennese visionary Hans Przibram.

Are living organisms--as Descartes argued--just machines? Or is the nature of life such that it can never be fully explained by mechanistic models? In this thought-provoking and controversial book, eminent geophysicist Walter M. Elsasser argues that the behavior of living organisms cannot be reduced to physico-chemical causality. Suggesting that molecular biology today is at the same point as Newtonian physics on the eve of the quantum revolution, Elsasser lays the foundation for a theoretical biology that points the way toward a (...) natural philosophy of organic life. Explicitly repudiating "vitalism" (the notion that the laws of nature need to be modified when applied to living organisms), Elsasser argues instead that the structural complexity of even a single living cell is "transcomputational"--that is, beyond the power of any imaginable system to compute. Beginning from this insight, Elsasser leads the reader through a step-by-step process that ultimately arrives at the conclusion that living and non-living matter are separated by "a no-man's land of irrationality." Trained in Germany as a physicist, Elsasser first pondered the implications of quantum mechanics for biology as early as 1951. The more closely he studied the inherent complexity of life, the more skeptical he became of the reductionist view of organisms as tiny machines. "An organism," he concluded, "is a source of causal chains which cannot be traced beyond a terminal point because they are lost in the unfathomable complexity of the organism." Like the physicist who works within the bounds of an unfathomable universe, Elsasser argues, the biologist must seek answers within a system that is no less unfathomable. (shrink)

The book of Bergson underlying the present study appeared in 1896. It is entitled “Matter and Memory” and is a philosophical disquisition into the relation and mutual limitations of organic life and inert matter. Bergson proposes to deal with this very general problem under the special aspect of a theory of the functioning of the human brain and the mechanism of ordinary memory. Such use of the inductive method, which starts from a special problem in order to arrive at results (...) that might be generalized later, might endear him to the exact scientist who has a healthy skepticism toward pure generalities. But let us for a moment remain in the realm of generalities in order to better circumscribe the subject: Few people would agree to an entirely mechanistic interpretation of organic life; hence there should be some point in biology at which the deviations from pure mechanism appear explicitly and in their fulness. For the present we shall adopt an intentionally oversimplified mode of expression. Let us say that mechanistic description is causal and that as our analysis progresses we must eventually arrive at a point where we can no longer trace the causal chains in their entirety. At that point we must replace causal “classical” physics by quantum mechanics and form our pictures of microscopic realities of organic matter in terms of the latter. Some of the pertinent problems have been pointed out by the present writer among others, following earlier suggestions by Niels Bohr. Suffice it here to say that certain processes of the atomic scale going on in a complex system such as the organic tissue essentially escape detailed observation that would allow us to determine the continuity of an entirely causal nexus. It is possible to make such observations, but they result in physical destruction of the very coherence of the organic tissue upon which the biological functioning depends. Bohr describes this condition by the term “generalized complementarity.” We cannot enter into a discussion of these problems here; let us adopt deliberately the oversimplified and somewhat vague expression that at some point indeterminacies become significant in the microscopic processes that take place in the organic body. We shall try to limit ourselves in this paper to the simplistic notion of a multiplicity of indeterminate events inserted into the play of molecular reactions that constitute the functioning of the organism from the viewpoint of the physicist and chemist.

A quarter of a century has elapsed since quantum mechanics was discovered. Perhaps it is not too much to say, in retrospect, that the time was ripe for this particular development. This is attested, not only by the speed with which the edifice of the theory was completed immediately following the basic discoveries of Heisenberg and Schrödinger, but also by the rapidity, well-nigh unprecedented in the history of science with which the new results were applied to almost every branch of (...) physics and chemistry. A mental readiness on the part of the scientists involved might have had much more to do with this than the facilities of modern communication systems. (shrink)

"The time-honored dualism of the mutually exclusive systems of thought, mechanistic biology on the one hand and vitalism on the other, expresses a pair of theoretical approaches which are both inadequate. We shall show how they can be replaced by an abstractly descriptive system of a different type that is far better adapted to the nature of biology"--Preface.

Hans Reichenbach, a philosopher of science who was one of five students in Einstein's first seminar on the general theory of relativity, became Einstein's bulldog, defending the theory against criticism from philosophers, physicists, and popular commentators. This book chronicles the development of Reichenbach's reconstruction of Einstein's theory in a way that clearly sets out all of its philosophical commitments and its physical predictions as well as the battles that Reichenbach fought on its behalf, in both the academic and popular (...) press. The essays include reviews and responses to philosophical colleagues, such as Moritz Schlick and Hugo Dingler; polemical discussions with physicists Max Born and D. C. Miller; as well as popular articles meant to clarify aspects of Einstein's theories and set out their philosophical ramifications for the layperson. At a time when physics and philosophy were both undergoing revolutionary changes in content and method, this book is a window into the development of scientific philosophy and the role of the philosopher.

Aus ganz unterschiedlichen Blickwinkeln, sei es aus musikhistorischer oder ethnomusikologischer Sicht, umkreisen zehn Beitrage das Thema aMusik - Zu Begriff und Konzepteno. Unter dieses Thema ein internationales Symposion in Berlin zu stellen, das zum Gedenken an Hans Heinrich Eggebrecht (1919-1999) veranstaltet wurde, erschien umso naheliegender, zumal Eggebrecht die Frage aWas ist Musik'o existenziell beruhrte, sie grundierte und sein Forscherleben als Musikwissenschaftler von den fruhen Veroffentlichungen nach dem Zweiten Weltkrieg bis zu den letzten Arbeiten durchzog. Inhalt Bruno Nettl: Was ist (...) Musik? Ethnomusikologische Perspektive Sabine Ehrmann-Herfort: Die Kantate.

Dans cet ouvrage, Gadamer (1900-2002) nous confie un veritable testament philosophique. Abordant des questions centrales de la pensee contemporaine, le maitre de l'hermeneutique livre ici ses dernieres reflexions sur des themes qui lui tiennent a coeur: l'art et la poesie, la reconnaissance et l'humanisme, l'amitie et l'ecoute. L'hermeneutique, selon Gadamer, est la theorie selon laquelle nous devons apprendre a ecouter.

In the late 1830s and early 1840s Hans. L. Martensen helped to introduce the thought of G.W.F. Hegel to the intellectual world of Copenhagen. Between Hegel and Kierkegaard offers the first English translations of three important early writings of Martensen in the philsophy of religion. These treatises evidence an original and critical interpretation of Hegel's thought from a speculative theological point of view. The heart of Martensen's philosophy of religion is the idea of freedom or personality grounded in its (...) relation to the divine. These writings exercised an important and formative influence on the young Kierkegaard, Martensen's student, even though Kierkegaard later became a formidable opponent and critic of Martensen.

A systematic effort is here made to express some of the general results of quantum mechanics in a conceptual form closer to ordinary language than is the case with most modern physics. Many of the implications of the theory appear much more clearly thereby, in particular the fact that the laws of quantum mechanics are only statistical propositions about classes, not referring to individual objects. Conversely, the microscopic structure of an object cannot be precisely defined in quantum mechanical terms. To (...) say that an object has a definite microscopic structure is an operationally meaningless statement; it is on the same level as saying in relativity that a selected coordinate system is “at rest.” This raises the need for a “theory of matching”: What is the best statement about the structure of an object, given that the tools of description are only statistical? A technique is known for this: the theory of inductive probabilities. There is no longer one true description but a manifold of statistical descriptions, some of which have a greater likelihood of being satisfactory than others. The main concrete application of this type of conceptual reasoning lies in its power to clean out the speculative underbrush which so far has prevented the transition from theoretical physics to theoretical biology.

History, Metaphors, and Fables collects the central writings by Hans Blumenberg and covers topics such as on the philosophy of language, metaphor theory, non-conceptuality, aesthetics, politics, and literary studies. This landmark volume demonstrates Blumenberg's intellectual breadth and gives an overview of his thematic and stylistic range over four decades. Blumenberg's early philosophy of technology becomes tangible, as does his critique of linguistic perfectibility and conceptual thought, his theory of history as successive concepts of reality", his anthropology, or his studies (...) of literature. History, Metaphors, Fables allows readers to discover a master thinker whose role in the German intellectual post-war scene can hardly be overestimated. (shrink)

The Hans Reichenbach Papers comprise published and unpublished manuscripts, lectures, correspondence, photographs, drawings, and related materials from his early student days until his death. The correspondence contains about 9000 pages to and from Reichenbach; it ranges over his entire career. Those with whom Reichenbach maintained lifelong contact include Rudolf Carnap, Ernst Cassirer, Herbert Feigl, Philip Frank, Carl Hempel, Sidney Hook, Paul Oppenheim and Wolfgang Pauli. In addition, there is significant correspondence with von Astor, Bergmann, Bertalanffy, Dingler, Dubislav, Einstein, Fraenkel, (...) Frank, Freundlich, Grelling, Grünbaum, Paul Hertz, Hutten, Jordan, Landé, von Laue, Lewin, C.I. Lewis, Charles Morris, Nagel, Neurath, Northrop, Planck, Quine, Regener, Rougier, Salmon, Schillp, Schlick, Scholz, Schrödinger, Martin Strauss, Tarski, Vaihinger, Weiss, Williams, Zawarski, and Zilsel. The correspondence provides a valuable source of information about Reichenbach’s personal and philosophical development. It also provides primary source material for research into one of the 20th century most influential philosophical movements. Reichenbach’s manuscripts include many of his own notes as a student. Some go as far back as his university days in science and mathematics. Some of the most significant of these notes are those taken by him as a student of Albert Einstein on the special and general theories of relativity. There are four such notebooks dating from 1918. In addition there are his student notes on astronomy, Planck and electricity, Hilbert’s “Statistical Mechanics” and “Problems and Principles.” He also kept many of his lecture notes from Germany, Turkey, and the United States. The number of lectures runs to over 100 and provides a glimpse into the problems of philosophy and how he presented them to his students. Many of his lectures discussed principles of radio and issues in philosophy and modern science, often in form of popularizations of questions in relativity and quantum theory delivered on radio programs for a wider audiences. In addition to this there are an abundance of notes, calculations, and diagrams used to draft both published and unpublished papers. (shrink)

Within psychiatric research, the field of 'technotherapy' has been centred primarily on attempts to assess the computer as a treatment tool. The situation of daily clinical usage is, however, often ignored within such research, as for instance in controlled clinical trials. Our empirical study illustrates how health professionals and clients use different concepts of science and health in the attempts of formulating standards for using computers in psychiatric practice. The psychiatrists at a major psychiatric hospital decided and justified clients' use (...) of computers on the basis of a 'techno-medical' quality assurance. At the same hospital the occupational therapists stressed the improvement of social relations as a treatment goal. And, at a psychiatric outside clinic the clients used concepts of 'normality' for articulating quality in computer use. Our study exemplifies how the use of computers is a multifaceted 'performance'. What is called for is a kind of research not limited by artificial borders of 'the context' and the 'user-perspective'. In much humanistic research as well as in action research concepts of 'context' and 'user-perspective' imply a somehow romantic view on practice as pure and uncontaminated by the outside world contrasted to a 'general' or an 'objective' way of knowing the world. These sharp distinctions were however difficult to maintain in our study, where health professionals and clients took local contingencies into account when they interpreted computer use, while they simultaneously drew on a socio-historical reservoir of resources.
