Being and Time

The different modes of state-of-mind and the ways in which they are interconnected in their foundations cannot be Interpreted within the problematic of the present investigation. The phenomena have long been well-known ontically under the terms "affects" and "feelings" and have always been under consideration in philosophy. It is not an accident that the earliest systematic Interpretation of affects that has come down to us is not treated in the framework of 'psychology'. Aristotle investigates the πάθη (affects] in the second book of his Rhetoric. Contrary to the traditional orientation, according to which rhetoric is conceived as the kind of thing we 'learn in school', this work of Aristotle must be taken as the first systematic hermeneutic of the everydayness of Being with one another. Publicness, as the kind of Being which belongs to the "they" (Cf. Section 27), not only has in general its own way of having a mood, but needs moods and 'makes' them for itself. It is into such a mood and out of such [139] a mood that the orator speaks. He must understand the possibilities of moods in order to rouse them and guide them aright.

How the Interpretation of the affects was carried further in the Stoa, and how it was handed down to modem times through patristic and scholastic theology, is well known. What has escaped notice is that the basic ontological Interpretation of the affective life in general has been able to make scarcely one forward step worthy of mention since Aristotle. On the contrary, affects and feelings come under the theme of psychical phenomena, functioning as a third class of these, usually along with ideation [Vorstellen] and volition. They sink to the level of accompanying phenomena.

It has been one of the merits of phenomenological research that it has again brought these phenomena more unrestrictedly into our sight. Not only that: Scheler, accepting the challenges of Augustine and Pascal, has guided the problematic to a consideration of how acts which 'represent' and acts which 'take an interest' are interconnected in their foundations. But even here the existential-ontological foundations of the phenomenon of the act in general are admittedly still obscure.

A state-of-mind not only discloses Dasein in its thrownness and its submission to that world which is already disclosed with its own Being; it is itself the existential kind of Being in which Dasein constantly surrenders itself to the 'world' and lets the 'world' "matter" to it in such a way that somehow Dasein evades its very self. The existential constitution of such evasion will become clear in the phenomenon of falling.

A state-of-mind is a basic existential way in which Dasein is its "there". It not only characterizes Dasein ontologically, but, because of what it discloses, it is at the same time methodologically significant in principle
