In this paper we argue that an operational organism concept can help to overcome the structural deficiency of mathematical models in biology. In our opinion, the structural deficiency of mathematical models lies mainly in our inability to identify functionally relevant biological characters in biological systems, and not so much in a lack of adequate mathematical representations of biological processes. We argue that the problem of character identification in biological systems is linked to the question of a properly formulated organism concept. (...) Lastly, we demonstrate how a decomposition of an organism into independent characters in the context of a specific biological process--such as adaptation by means of natural selection--depends on the dynamical properties and invariance conditions of the equations that describe this process.

The immediate successors of Kant in classical German philosophy considered a subjectivity irreducible to objecthood as the core of personhood. The thesis of an irreducible subjectivity has, after the German idealists, been advocated by the phenomenological movement, as well as by analytical philosophers of self-consciousness such as Hector-Neri Castaneda and Sydney Shoemaker. Their arguments together show that self-consciousness cannot be reduced to a relation whereby a subject grasps itself as an object, but that there must be a core of subjectivity (...) always already familiar with itself before reflection. A number of contemporary accounts of self-consciousness are unaware of these old and new arguments, and flawed in that they do not account for the core 'non-objectal subjectivity' necessary for self-consciousness and.

In the development of modern philosophy self-consciousness was not generally or unanimously given important consideration. This was because philosophers such as Descartes, Kant and Fichte thought it served as the highest principle from which we can 'deduce' all propositions that rightly claimed validity. However, the Romantics thought that the consideration of self-consciousness was of the highest importance even when any claim to foundationalism was abandoned. In this respect, Hölderlin and his circle, as well as Novalis and Schleiermacher, thought that self-consciousness, (...) itself, was not a principle but must be ranked on a minor or dependent level, and presupposed the Absolute as a superior but inaccessible condition or ground. This reservation did not hinder them from recognising that the foundationalist Fichte was the first to have shown conclusively that from Descartes, via German Rationalism and British Empiricism, up to Kant, self-consciousness was misconceived of as the result of an act of reflection by which a second-order act bent back upon a first-order act that is identical to itself. This conception entailed circular entanglements and infinite regresses, and was too high a price to pay. Whereas Fichte thought pre-reflexive self-awareness was a philosophical principle, the Romantics and their vehement critic Kierkegaard, abandoned the idea of self-consciousness as a foundational starting point of philosophy. Instead, they founded self-consciousness on transcendent Being, a prior non-conceptual consciousness ('feeling') and reproached Fichte for having fallen back into the repudiated reflection model of self-consciousness.

The following contribution1 was inspired by Cleo Condoravdi’s article on NPI licensing in temporal clauses (Condoravdi, this volume). Condoravdi gives a coherent and comprehensive account of be- fore which crucially involves coercion of propositions to the earliest or maximal times at which the propositions are true, and a modal component for non-factual interpretations. I argue for a nonmodal, non-coercive analysis of clauses like [A before B] as ‘A is the case when B has not been the case’, triggering a conversational (...) implicature that B will be the case later. I will discuss temporal operators involving measure phrases, like three hours before, and I will show that so-called “expletive” negation in corresponding clauses in German is, in fact, interpreted as negation.

This talk is based on Krifka (2001). Its topic is the interpretation of quantifiers in questions. I will use English data for illustration, but the phenomena to be discussed appear to be general enough to be relevant for other languages as well, at least those languages that have nominal quantifiers.

This book represents an effort to understand very old questions about biological form, function, and the relationships between them. The essays collected here reflect the diversity of approaches in evolutionary developmental biology, including not only studies by prominent scientists whose research focuses on topics concerned with evolution and development, but also historically and conceptually oriented studies that place the scientific work within a larger framework and ask how it can be pushed further. Topics under discussion range from the use of (...) theoretical and empirical biomechanics to understand the evolution of plant form, to detailed studies of the evolution of development and the role of developmental constraints on phenotypic variation. The result is a rich and interdisciplinary volume that will begin a wider conversation about the shape of Evo Devo as it matures as a field. (shrink)

Modern Standard German does not have distinct forms for nominatives and accusatives in the feminine gender. This is not only unique within Germanic languages, but also quite remarkable from a typological and functional viewpoint, under the plausible assumption that feminine NPs do not differ in animacy from masculine NPs. I will discuss the loss of the N/A distinction for feminines in detail and speculate about possible reasons – among others, that the referents of feminines are not typically animate, that the (...) syncretism was modelled after a similar syncretism in the plural, and that a sexist bias of the speech community in which the syncretism originated influenced a core part of the grammar of their language.

Caenorhabditis elegans is a tiny worm that has become the focus of a large number of worldwide research projects examining its genetics, development, neuroscience, and behavior. Recently several groups of investigators have begun to tie together the behavior of the organism and the underlying genes, neural circuits, and molecular processes implemented in those circuits. Behavior is quintessentially organismal—it is the organism as a whole that moves and mates—but the explanations are devised at the molecular and neurocircuit levels, and tested in (...) populations using protocols that span many levels of aggregation. Following a brief review of the main relevant features of C. elegans, I describe some of these circuits, and then discuss two contrasting approaches in behavioral genetics and neural network analysis of the worm. Finally, I outline the rudiments of a “field and focus” explanation model using the two contrasting approaches. (shrink)

Im Rahmen einer Erörterung der Philosophie J.G. Fichtes liegt die wissenschaftliche Bedeutung J.B. Schads nicht darin, daß dieser besonders scharfsinnig interpretierend oder kommentierend an die Wissenschaftslehre herangegangen sei. Das weist er selbst ausdrücklich von sich. Vielmehr kann die philosophische Leistung Schads, die es rechtfertigt, auf einem Fichte-Kongreß auch auf ihn näher einzugehen, darin gesehen werden, daß er als erster den Versuch macht, die Philosophie Fichtes nicht nur allgemeinverständlich darzustellen, sondern sie auch relativ frei aus sich selbst heraus nachzuentwickeln.

In this article, various objections will be discussed that have been put forward against ethical relativism, but which haven’t been considered seriously enough on the part of relativists and have been overrated on the part of their opponents. The objections will be concentrated into three arguments: the action-theoretic, the epistemological and the truth-theoretic argument. The article will discuss whether they can be rebutted by proponents of the two main types of relativism: indexical relativism and truth-relativism. The conclusion will be as (...) follows: one version of indexical relativism, the analytical version, gets into serious troubles by the action-theoretic argument, while its revisionary version will remain unaffected, the epistemological argument fails with respect to indexical relativism and stands on shaky ground as regards truth-relativism, the truth-theoretic argument puts considerable pressure on truth-relativism.
