Moods as Groundlessness of the Human Experience. Heidegger and Wittgenstein on Stimmung

The paper analyzes the ontological meaning of mood (Stimmung) in Heidegger’s conception of Attunement (Befindlichkeit), in order to relate this notion of Stimmung specifically to our “attunement” (Übereinstimmung) to a form of life, as conceived in Wittgenstein’s philosophy of language. It claims that moods spell out the constitutive impossibility to grasp and found the human experience as such. However, this impossibility is not a lack of human knowledge, but rather corresponds to the necessary opacity, indeterminability and groundlessness of every human experience, which make it possible as such. The paper argues that the ontological mood of anxiety in Heidegger’s thought cannot be understood as a dark feeling, since it points to a constitutive sense of disorientation, which involves the impossibility to found and ensure the very familiarity of our ordinary experience. Moreover, the paper claims that the same impossibility is also involved in our “attunement” to language and to a form of life, as described by Wittgenstein in his Philosophical Investigations. By analyzing the mood of trust sketched out by Wittgenstein in On Certainty, the paper suggests that the ontological mood of trust, as the groundless certainty of our praxis, points to the very impossibility to found and ensure every human experience. From this perspective, moods reveal the groundlessness of human experience and make us acknowledge it.
