In everyday life, we constantly encounter and deal with useful things without pausing to inquire about the sources of their intelligibility. In Div. I of Being and Time, Heidegger undertakes just such an inquiry. According to a common reading of Heidegger's analysis, the intelligibility of our everyday encounters and dealings with useful things is ultimately constituted by practical self-understandings. In this paper, I argue that while such practical self-understandings may be sufficient to constitute the intelligibility of the tools and equipment (...) specific to many practices, these “tools of the trade” are only a small portion of the things we encounter, use, and deal with on a daily basis. Practical self-understandings cannot similarly account for the intelligibility of the more mundane things—like toothbrushes and sidewalks—used in everyday life. I consider whether an anonymous self-understanding as “one,” “anyone,” or “no one in particular” —das Man—might play this intelligibility-constituting role. In examining this possibility, another type of self-understanding comes to light: cultural identities. I show that the cultural identities into which we are “thrown,” rather than practical identities or das Man, constitute the intelligibility of the abundance of mundane things that fill our everyday lives. Finally, I spell out how this finding bears on our understanding of Heidegger's notion of authenticity. (shrink)

In this article, I examine various aspects of the application of Heidegger's motif of interpretative articulation (the core phenomenological motif of existential analytic) to the constitutional analysis of meaningful objects in scientific research that are contextually ready-to-hand. It is my contention that not only the concepts of the ‘fore-structure of understanding’ and the ‘as-structure of interpretation’, but also the extended concepts of the ‘hermeneutic fore-structure of meaning constitution’ and ‘characteristic hermeneutic situation’ are the keys to understanding the interpretative nature of (...) scientific research. The paper applies the constitutional analysis of hermeneutic phenomenology to several phenomena of scientific research—constitution of meaningful objects, situational fulfilment of a domain's general project, production of a domain's thematically given objects, implementation of readable technologies to what is contextually ready-to-hand, reading hypothetical theoretical objects, and exegetical textualizing within interrelated practices. The study is supplied with exemplary illustrations from enzymology and biochemistry. The correlation between a domain's interpretative articulation and the appropriation of research possibilities within the research everydayness is addressed. Special attention is paid to the belief in and reading of intracellular enzymes as hypothetical theoretical objects. (shrink)
