In this essay, we explore the various aspects of hermeneutic relativity that have rarely been explicitly discussed. Our notion of “hermeneutic relativity” can be seen as an extension, with significant revisions, of Gadamer’s notion of Vorurteil. It refers to various choices and constraints of the interpreter, including beliefs concerning the best way of doing philosophy, what criteria are to be used to evaluate competing interpretations, and so on. The interpreter cannot completely eliminate the guidance and constraint originating from his/her “background.” However, in principle the interpreter can “choose” to be guided by other constraints. Hence, we speak of “choices” or “commitments.” Hermeneutic relativity is the major cause for the variation of competing interpretations.

We argue that all general concepts are family resemblance concepts. These include concepts introduced by ostension, such as colour(s). Concepts of colour and of each of the specific colours are family resemblance concepts because similarities concerning an open‐ended range of colour or of appearance features crop up and disappear. After discussing the notion of “same colour” and Wittgenstein's use of the phrase “our colours”, we suggest family resemblance concepts in one tradition can often be extended to family resemblance concepts in another tradition, illustrated by Wittgenstein's use of the words Spiel and “game”.

In a rarely quoted paper, published in 1958 in the American Journal of Physics, T. Ehrenfest-Afanassjewa introduced the idea that the concept of chance as employed in physics is subject to what she called a ‘Limited Belief in Chance’. In this paper I elaborate the latter concept and the distinction between absolute chance and relative randomness, where the latter, but not the former, is governed by the theory of probability. I argue that in the twentieth century virtually nobody believes seriously in the possiblity of absolute chance, whereas the concept of chance in the Scientific World Picture is only ‘chancy’ relative to a limited belief in chance grounded in the Manifest World Picture of an orderly world.

According to the state of the art in psychology and philosophy, colour sensations are located in a 'quality space'. This space has three dimensions: hue , saturation , and brightness. This space is structured further via a small number of primitive hues or landmark colours, usually four or six . It has also been suggested that there are eleven semantic universals — the six colours previously mentioned plus orange, pink, brown, purple, and grey. Against the standard view, we argue that colour might better be regarded as the outcome of a social-historical developmental trajectory in which there is mutual shaping of philosophical presuppositions, scientific theories, experimental practices, technological tools, rhetorical frameworks, and their intercalated and recursive interactions with the lifeworld. That is: the domain of colour is the outcome of interactive processes of scientific, instrumental, industrial, and everyday lifeworlds

In this essay, we present a theory of intercultural philosophical dialogue and comparative philosophy, drawing on both hermeneutics and analytic philosophy. We advocate the approach of “de-essentialization” across the board. It is true that similarities and differences are always to be observed across languages and traditions, but there exist no immutable cores or essences. “De-essentialization” applies to all “levels” of concepts: everyday notions such as green and qing 青, philosophical concepts such as emotion(s) and qing 情, and philosophical categories such as forms of life and dao 道. We argue that interpretation is a holistic multi-directional process constrained by the principle of mutual attunement. It is necessary to assume that “the other” is a human being, who, in most cases, is consistent and stating that which is true or right. This is the condition of possibility for intercultural philosophical dialogue and comparative philosophy. No more necessary conditions are needed. There is no need to presuppose concepts or categories that are universal for all humans and their languages (such as emotion(s) and qing 情)

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.

Probably colour is the best worked-out example of allegedly neurophysiologically innate response categories determining percepts and percepts determining concepts, and hence biology fixing the basic categories implicit in the use of language. In this paper I argue against this view and I take C. L. Hardin's Color for Philosophers [1988] as my main target. I start by undermining the view that four unique hues stand apart from all other colour shades (Section 2) and the confidence that the solar spectrum is naturally divided into four categories (Section 3). For such categories to be truly universal, they have to be true for all peoples and in Section 4 I show that Berlin and Kay's [1969] widely quoted theory of basic colour categories is not sufficiently supported to lend it any credibility.Having disposed of the view that inspection of language or ‘pure’ perception unveils the universal colour categories. I turn to neurophysiological and psychophysical theories of colour vision to see whether they provide a more solid basis for deciding what the innate response categories are. In Section 5 I show that Hardin's account of the opponent-process theory neither supports his view that ‘colour-coding’takes place early in the visual neural pathway, nor his view that knowledge of colour vision science will help us solve many philosophical mysteries about colour.In Section 6 I give a more detailed review of what is known today about the neurophysiology of colour vision and I show that there's nothing in the brain which could be called a colour module, let alone a module with homunculi for particular basic colour categories. In Section 7 I show that psychophysical models do not support such rigid constraints on category formation either. Hence (Section 8), at least in the case of colour, current science supports a plasticity in the formation of categories that goes far beyond the requirements of those naturalistic philosophers who would like to ground primitive concepts in biology.

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.

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.
