In this paper, I argue against the interpretive view that locates an “undifferentiated mode” – a mode in which Dasein is neither authentic nor inauthentic – in Being and Time. Where Heidegger seems to be claiming that Dasein can exist in an “undifferentiated mode”, he is better understood as discussing a phenomenon I call indifferent inauthenticity. The average everyday “Indifferenz” which is often taken as an indication of an “undifferentiated mode”, that is, is better understood as a failure to distinguish (...) between the possibilities of authentic and inauthentic self-understanding. Dasein's average everyday self-understanding is indifferent to this distinction, and I show that this is precisely what renders it inauthentic. Recognizing this distinction, however, is not enough to render Dasein authentic. Rather, it opens up the possibility of a non-indifferent inauthenticity and what Heidegger calls the possibility of “genuine failure”. To read an “undifferentiated mode” into Being and Time is to misunderstand its methodological progression from Dasein's average everyday, inauthentic self-understanding to its authenticity – “to the thing itself”. A select few passages may at first seem to indicate otherwise. However, Being and Time – like both being in general and Dasein itself – cannot be properly understood “without further ado”.\.

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)
