This paper begins as a reflective account of Heidegger’s notion of mood. Mood according to Heidegger is part of our thrownness in that we find ourselves so attuned. A mood is more than something subjective within the individual; it is not primordially an interior condition. Rather a mood is an atmosphere that is already there that sets the tone for our being-in-the-world. In this way mood opens us up or tunes us into a disclosure of what is important to us. Attunement is another word that captures the constituting nature of mood; that is, mood discloses not only what matters to us but also discloses our being in relation to our situatedness. A mood is pervasive; it is an atmosphere that saturates our being. Using a paradigm case from my doctoral thesis as well as a casual conversation with an individual encountered on public transportation, I will explore the meaning and experience of mood for these two individuals, myself as researcher, and conference attendees listening to the case narratives.
