Furthermore, I am always found in a mood, a Stimmung. This is mood is the strong Aristotelian sense of pathos, a passion of the soul or an affect, something befalls us and in which we find ourselves. The passions are not, for Heidegger, psychological colouring for an essentially rational agent. They are rather the fundamental ways in which we are attuned to the world. Indeed, musicologically, Stimmung is linked to tuning and pitch: one is attuned to the world firstly and mostly through moods. One of the compelling aspects of Heidegger's work is his attempt to provide a phenomenology of moods, of the affects that make up our everyday life in the world.As a corollary, music is the language of moods.
This is another way of approaching his central insight: that we cannot exist independently of our relation to the world; and this relationship is a matter of mood and appetite, not rational contemplation.
Such moods disclose the human being as thrown into the 'there' of my being-in-the-world. As Jim Morrisson [singer for The Doorrs] intoned many decades ago, 'Into this world we're thrown'.
