The purpose of this paper is to explore the semantics of metaphoric language in scientific contexts. According to the theory of metaphor advanced below, the benchmark of a metaphoric expression is the implicit transfer of semantic features across incongruous semantic fields. This transfer results in a conceptual variation of "meaning" in the receiving semantic field. Thus, the theory of metaphor rests on semantic field theory. Existing semantic approaches to metaphor are evaluated in Section 1. In Sections 2 and 3 an (...) alternative theory is introduced through an analysis of the mechanics of the feature transfer process followed by a discussion of some methodological cues for deciphering the metaphor's "meaning." As I explore in Section 4, this theory of metaphor explains how all metaphoric expressions are potentially literal depending on the general compliance of the community of speakers. Consequently, concept formation in scientific contexts is, in large measure, metaphoric. Finally, I argue in Section 5 that metaphoric concept formation is an essential aspect of scientific reasoning for the purpose of solving conceptual problems. (shrink)

The aim of this article is to analyse the role of metaphors for the infertile body in the context of assisted reproduction, using conceptual metaphor theory as a framework, and to evaluate the moral significance of these metaphors. This sub-study is part of a larger study examining the biosafety practices of new biotechnologies in Latvia. In the sub-study, special attention was paid to metaphors used by assisted reproductive technology users, egg donors and experts. It can be concluded that not only (...) does the infertility experience influence the choice of metaphors, but the use of certain metaphors can also change the infertility experience. In this process the practice of infertility treatment and the meaning of the body are socially and culturally shaped. The main groups of metaphors for the infertile body discovered through interview analysis are: order/disorder, the body as a resource, the body as a container, the body as a project, and anthropomorphization of gametes.

In this paper, we examine the use of the term ‘life’ in the debates within and about synthetic biology. We review different positions within these debates, focusing on the historical background, the constructive epistemology of laboratory research and the pros and cons of metaphorical speech. We argue that ‘life’ is used as buzzword, as folk concept, and as theoretical concept in inhomogeneous ways. Extending beyond the review of the significant literature, we also argue that ‘life’ can be understood as aBurstwordin (...) two concrete senses. Firstly, terms such as life easily turn into fuzzy, foggy and buzzy clouds of nonsense, if their use is not appropriately reflected. In these cases, the semantic orientation is detonated. This is theBurstword Icharacteristic of the concept of ‘life’ that we reveal for its unclear terminological use. Secondly, and in contrast toBurstword I, we show that the concept of ‘life’ can be used in a methodologically controlled way. We call this kind of useBurstword II. Here the concept of ‘life’ fulfils the function of expanding an inadequately narrow disciplinary or conceptual focus in different discursive contexts. In this second sense, ‘life’ receives an important operational function, for instance as a transdisciplinary research principle. It turns out that the innovative function and paradigm-changing power of metaphorical speech belong here as well. Finally, we illustrate three ethically relevant examples that show how ‘life’ can be applied asBurstword IIin the context of synthetic biology. (shrink)

Two points of contact are explored between contemporary philosophy of science and Dialectical Materialism. The first point deals with the interaction view of metaphor as an exemplification of the law of the unity of opposites. The contradiction is then noted between the strategy and tactics of much analytical philosophy and the lesson to be learnt from this account of metaphor. The concern to change category habits into category disciplines rules out the process of conceptual change of the interaction view. G. (...) A. Paul's dismissal of Lenin's theory of reflection is then criticized in the light of the interaction view. (shrink)
