Beyond the Tools of the Trade: Heidegger and the Intelligibility of Everyday Things

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 (such as being a gardener, shoemaker, teacher, mother, musician, or philosopher). 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.
