Husserl’s notion of “sense” has often been interpreted through a Fregean lens. I will show that Husserl saw it as an acquaintance with the background or horizon of perceptual objects. He understands reason (Vernunft) as prescribing rules for performance with regard to perceptual objects. Thus Husserl’s view has a wider scope of experience than Kant’s sense of it as a pre-reflective acquaintance with one’s environment. After Ideas I Husserl develops these notions as part of his theory of the intersubjective world. (...) Heidegger takes over the insights of Husserl and brings out the performative turn inherent in phenomenology by critiquing Husserl’s orientation to theoretical perceptual experience. The reference of performative expressions is not determined by the contents but by performance. What is disclosed in the phenomenological notion of sense is the background against which human existence is to be understood. (shrink)

In this paper, I will focus on the phenomenological notion of sense which Husserl calls in Ideen I noematic sense. My reading of Ideen I is based on the interpretation of noema as “object as it is intended”. This notion is developed from “filling sense” in LU. Similar to the Russellian “knowledge by acquaintance”, Husserl means by this notion the direct intuitive acquaintance with an intentional object. However, unlike Russell, Husserl doesn’t restrict this notion to sense data, but extend it (...) to the acquaintance with the perspective way of appearance of an intentional object (Erscheinungsweise, Abschattungen). This is because, unlike Frege, Husserl includes not only intension (Materie), but also illocutionary force (Aktqualität) into his notion of sense (LU, 6. Untersuchung, p. 617). This performative notion of sense requires him to take account of the acquaintance with the background of speech acts as a constitutive part of the broadest notion of sense (Ideen I, p. 233f., 322). If a conjecture e.g. about the back side of a cube: “the back side must be a square”, changes through a perception into a claim about it: “this side is indeed a square”, the change of the illocutionary forces, that is, the “filling sense” of the perception is expressed not by intentional materials (side, square etc.), but by indexicals, modal verbs or tenses, which are understood in a direct acquaintance with the perspective appearance of the cube. Thus, “the changing noematic way of appearance of the whole object as sense” (Husserliana vol. XI, p. 333) is the background or horizon, in implicit acquaintance with which illocutionary forces (Aktqualität in LU, noetischer Charakter in Ideen I) of propositional attitudes towards perceptual objects can be understood.

Was heißt die existenziale Analytik? Um diese Grundfrage der Fundamentalontologie zu beantworten, geht der Autor von der Problematik des Ich-Sagens aus. Während der Marburger Vorlesungen entstand der Begriff Dasein durch Heideggers Umdeutung der aristotelischen Seele anhand des leiblich-lebensweltlichen Subjektivitätsbegriffs Husserls. Dabei entwickelte Heidegger mittels des Diltheyschen Begriffs Bedeutsamkeit das Noema als Zeug hermeneutisch weiter. Um das Sein eines Ich durch Handlungsprädikate auszulegen, ist es notwendig, mit der Bedeutsamkeit der Welt vorbegrifflich vertraut zu sein. Das Verstehen als Weltvertrautheit ist das Existenzial, (...) d. h. die Bedingung der Möglichkeit für das Ich-Sagen. So schlägt der Autor vor, die Schemata: Das Umwillen seiner , das Wovor und das Um-zu als Schematismus der Handlung zu deuten. Darüber hinaus wird untersucht, warum die geschichtliche Rationalität trotz seiner Aufnahme der praktischen Philosophie Aristoteles’ und Kants von Heidegger vernachlässigt wurde. (shrink)
