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 ..

In this article, I look at those passages in the Zhuangzi usually associated with “uselessness.” I discuss in what way these passages may have been suggestive to Martin Heidegger to explain his ideas of the necessity of the other thinking and of the “waiting people” being entirely unusable to others. Then I make some brief comments concerning basic conditions of interpretation, using examples taken from the Zhuangzi passages discussed. These conditions include family resemblance across the board, a principle of agreement, and the issue of “planetarization”.

Amidst the progress being made in the various (sub-)disciplines of the behavioural and brain sciences a somewhat neglected subject is the problem of how everything fits into one world and, derivatively, how the relation between different levels of discourse should be understood and to what extent different levels, domains, approaches, or disciplines are autonomous or dependent. In this paper I critically review the most recent proposals to specify the nature of interdiscourse relations, focusing on the concept of supervenience. Ideally supervenience is a relation between different discourses which has all the advantages of reduction, but without its disadvantages. I apply the more abstract considerations to two concrete cases: schizophrenia and colour. Usually an interlevel or interdiscourse relation is seen as asymmetrical: the overlaying discourse depends on the underlying discourse (and not vice versa), where the out- or un-spoken assumption is that the ultimate underlying discourse is physical. Instead I argue that scientific categories referred to in interdiscourse relations are, ultimately, dependent on common sense categories and common sense normative criteria. It is the manifest categories and common sense ideas about what is reasonable and what is right that determine the relevant categorisations at the deeper, underlying levels. I suggest that the implications of this are not merely methodological or epistemological.

Using the notorious bridge law “water is H 2 O” and the relation between molecular structure and quantum mechanics as examples, I argue that it doesn’t make sense to aim for specific definition(s) of intertheoretical or interdiscourse relation(s) between chemistry and physics (reduction, supervenience, what have you). Proposed definitions of interdiscourse and part-whole relations are interesting only if they provide insight in the variegated interconnected patchwork of theories and beliefs. There is “automatically” some sort of interdiscourse relation if different discourses claim to have something to say about the same situation (event, system), which is the basis of (contingent) local supervenience relations, which, proper empirically support being provided, can be upgraded to ceteris paribus bridge laws. Because of the ceteris paribus feature, and the discourse dependence of event identification, there is at best only global supervenience of the “special sciences” on the physical (and of parts of physics on other parts of physics)

In this target article the following hypotheses are discussed: (1) Colour is autonomous: a perceptuolinguistic and behavioural universal. (2) It is completely described by three independent attributes: hue, brightness, and saturation: (3) Phenomenologically and psychophysically there are four unique hues: red, green, blue, and yellow; (4) The unique hues are underpinned by two opponent psychophysical and/or neuronal channels: red/green, blue/yellow. The relevant literature is reviewed. We conclude: (i) Psychophysics and neurophysiology fail to set nontrivial constraints on colour categorization. (ii) Linguistic evidence provides no grounds for the universality of basic colour categories. (iii) Neither the opponent hues red/green, blue/yellow nor hue, brightness, and saturation are intrinsic to a universal concept of colour. (iv) Colour is not autonomous

While in the research area known,as ’philosophy of science' there is a growing interest in separate disciplines of the empirical sciences, applied sciences and even technologies, one can find hardly any reference to the discipline of chemistry other than some preliminary discussions of chemical concepts or studies concerning the rational reconstruction of the history of chemistry. No analyses, which might be called 'philosophy of chemistry’ can be found to date. It is hoped that this review paper on what has been published on the philosophy of chemistry will show that chemistry is a philosophically rich field. After an introduction, in section 2, a more detailed classification is given of the various areas from which a (marginal) interest in the philosophy of chemistry has emerged.In section 3 there is a review of the opinions on the subject matter of chemistry, be it straightforward definition or indications of the relation to other natural sciences, in particular physics. In section 4 publications on the philosophy of chemistry are reviewed which fit the conventional format of the philosophy of science (discussing laws, theories,explanations, models). In section 5 some of the literature on the concept of chemical species is reviewed. In section 6 and 7 a review of the literature on the concepts of chemical structure and chemical reactions is presented.

The primary purpose here is to ascertain what Heidegger's comportment toward East-West dialogue is most plausibly like in the light of his philosophical concerns and orientations. Considering that one should not uncritically take at face value occasional remarks by Heidegger that seem to suggest that he is preparing an East-West dialogue, we will proceed from Heidegger's own path of thinking and bring to light fundamental presuppositions in his thought and the response he may accordingly give to the issue of East-West dialogue.
