Models underlying the use of similarity considerations, dimensionless numbers, and dimensional analysis in chemical engineering are discussed. Special attention is given to the many levels at which models and ceteris paribus conditions play a role and to the modeling of initial and boundary conditions. It is shown that both the laws or dimensionless number correlations and the systems to which they apply are models. More generally, no matter which model or description one picks out, what is being modeled is itself a model of something else. Instead of saying that the artifact S models the given B, it is therefore better to say that S and B jointly make up B and S

In this paper my aim is to shed light on the common behavior of human beings by looking at '' first contacts '': the situation where people with unshared histories first meet. The limits of the human life form are given by what is similar in the common behavior of human beings. But what is similar should not be understood as something that is biologically or psychologically or transcendentally shared by all human beings. What is similar is what human beings would recognize as similar in first or other contacts-a similarity that is, in a way, transcendentally grounded, but the content of this grounding remains tied to the local situation of actual encounters. To be a human person, it is both an empirical and a transcendental precondition that one knows the certainties of particular form of life and that one is capable of recognizing and dealing with an indefinite variety of human behaviors. Because I participate in form of life, I can interact with other form of life. By considering first contacts and by interacting with other communities, one can learn to understand better what the common behavior of human beings is/are.

In this article, we trace and elucidate Heidegger’s radical re-thinking on the relation between science and technology from about 1940 until 1976. A range of passages from the Gesamtausgabe seem to articulate a reversal of the primacy of science and technology in claiming that “Science is applied technology.” After delving into Heidegger’s reflection on the being of science and technology and their “coordination,” we show that such a claim is essentially grounded in Heidegger’s idea that “Science and technology are the Same [das Selbe].” In addition, we argue that, although different ontic epochs can be distinguished in the evolvement of science and/or technology, for Heidegger there is only one unique ontological Epoch of modernity that encompasses various ontic epochs. Therefore, the change from an “epoch of objectivity” to an “epoch of orderability [Bestellbarkeit]” cannot be considered to be an ontological shift. Furthermore, it is not right to ascribe to Heidegger the view that the development of quantum physics signals the beginning of a new ontological Epoch

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 paper I evaluate the soundness of the prototype paradigm, in particular its basic assumption that there are pan-human psychological essences or core meanings that refer to basic-level natural kinds, explaining why, on the whole, human communication and learning are successful. Instead I argue that there are no particular pan-human basic elements for thought, meaning and cognition, neither prototypes, nor otherwise. To illuminate my view I draw on examples from anthropology. More generally I argue that the prototype paradigm exemplifies two assumptions that dominate cognitive science: (1) If human beings use words they mean something particular and what they mean can be discovered by scientific methods. (2) There is a fixed number of domains of categorization, each made up of a fixed number of basic categories. I suggest that these two assumptions lead to Brave New World

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 paper I present a historiography of the recent emergence of philosophy of chemistry. Special attention is given to the interest in this domain in Eastern Europe before the collapse of the USSR. It is shown that the initial neglect of the philosophy of chemistry is due to the unanimous view in philosophy and philosophy of science that only physics is a proper science (to put in Kant's words). More recently, due to the common though incorrect assumption that chemistry can in principle be reduced to physics, the neglect continued, even when interest in sciences such as biology and psychology entered more strongly in philosophy of science. It is concluded that chemistry is an autonomous science and is perhaps a more typical science than physics.

The book is an “introductory” reconstruction of Davidson on interpretation —a claim to be taken with a grain of salt. Writing introductory books has become an idol of the tribe. This is a concise book and reflects much study. It has many virtues along with some flaws. Ramberg assembles themes and puzzles from Davidson into a more or less coherent viewpoint. A special virtue is the innovative treatment of incommensurability and of the relation of Davidson’s work to hermeneutic themes. The weakness comes in a certain unevenness. While generally convincing and well written, the book has low points which may leave the reader confused or unconvinced. Davidson is the hero in this book, and our hero is sometimes over idealized.

Recent discussions about the anthropic principle and the argument from design can perhaps be summarized as follows : The world is very unusual, so it must have been made by an intelligent creator. The world is very unusual, but unusual things do occur by chance. Both and , in their ordinary interpretations, have been labelled probabilistic fallacies. In my paper I will discuss in particular the following two aspects: The contemporary relevance of Cicero's discussions on chance. The fact that any talk of chance events is only possible subject to the more encompassing idea of "limited belief in chance"

In this paper I argue that all proposals for demarcation criteria distinguishing between scientific and non-scientific knowledge, have failed. Moreover, there is not a single set of epistemic virtues that characterizes 'good' knowledge, nor is there such a set that characterizes science. There are many different epistemic virtues and no universal rules about how they are to be applied in particular cases. Different virtues may dominate in different knowledge domains. In the 'same' domain there are neither universal nor domainspecific rules as to how to weigh different virtues. Different virtues may provide conflicting assessments of a knowledge claim. After glancing at contemporary epistemology in the analytic tradition, I conclude there is little interest in the question of metajustification of epistemic virtues. When it does come up, appeal is made to intuitions that are not grounded in philosophy , but in manifest life forms. Finally, I present pointers that should guide the application of the very general meta-epistemic virtues 'fitting with experience' and 'fitting with earlier knowledge': [i] rationality should be understood as bridled irrationality, [ii] knowledge should be evaluated in terms of rightness, not truth, [iii] any final grounding of epistemic virtues has to fall back on the manifest life forms
