Abstract

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Intentionalität aus semiotischer Sicht. Peirceanische PerspektivenChristian StrubStefan Kappner Intentionalität aus semiotischer Sicht. Peirceanische Perspektiven. Berlin/New York: de Gruyter2004, ISBN 3–11-018288–2, 432 pp.1. Problem focusKappner intended only partially a Peirce-interpretation; he attempts to think further along with Peirce, and he succeeds as well. The first chapter serves as a sketch of the problem of intentionality from a historical perspective, starting from Brentano. Kappner formulates the problem correctly by stating that from the contemporary standpoint on the one hand every sort of methodological mind—body dualism is obsolete, because the mainstream of research has adopted a methodological physicalism along with an anti-foundationalistic epistemology; yet on the other hand our common sense view of psychic and thus also of intentional phenomena, which is inclined towards just such a dualism, must be taken into consideration. The systematic task thus consists in describing the particular quality of psychic phenomena in such a manner that this description "is compatible with methodological naturalism" (47). Kappner's main concern is thus the attempt to anchor the intentionality of thoughts and of human consciousness in more primitive forms of intentionality which are already exhibited by non-psychic goal-oriented natural processes. The solution to this task must accomplish two things: firstly, Kappner must justify the distinction between three types of "carriers" of "intentionality": concrete objects which intentionally contain an object in themselves, i.e. signs (381f.): Ch. 7; organisms which are capable of producing "inner signs for the simulation of external processes" (cf. 320–326: insightful behavior) (382f): Ch. 8; organisms which are capable of understanding this production as their own (self-consciousness) (383): Ch. 9. I will call this distinction the "internal differentiation thesis" (IDT). Secondly, Kappner must demonstrate that these three types of carriers are founded in one another. Over and above this, Kappner asserts that sign-intentionality is founded in something which he (with Arno Ros, 263, cf. 144) calls "quasi-intentionality" (Ch. 6). I will call this the "founding thesis" (FT). Obviously FT presupposes IDT, but not vice versa. Kappner claims to have successfully concluded such an ambitious naturalization program (342). Even when one [End Page 439] does not always agree with the partial solutions of Kappner, reading the book is definitely rewarding, as it shows in what a precisely differentiated manner one can reflect on a central problem of the "philosophy of mind" using Peirce's array of semiotic instruments.The reader is, naturally, astonished to hear the name Peirce in the context of a program for the naturalization of intentionality, for Peirce himself never used the concepts of "intention" and "intentionality" in the sense in which Brentano used them (47, 66), and himself clearly espoused an antifoundationalism and a methodological monism—but never a methodological naturalism; rather its opposite, namely a methodological idealism which can only conceive of physical properties as derived from psychic properties (synechism; 50–54). The reader is all the more eager to see how Kappner will prove his thesis to the effect that Peirce nevertheless has made a systematic contribution to the solution of the problem of intentionality under contemporary conditions. The decisive methodological step of Kappner (60) in Ch. 2 consists in declaring Peirce's metaphysics to be independent of his epistemic realism, which holds reality to be independent of the subject's mode of access to this reality. It is first at the end of the work that Kappner can precisely formulate what he means by Peircean naturalism: "For [Peirce], it is not primarily a question of how in (mere) thought relations to real things can be produced [as it is for Brentano and Husserl], but rather the opposite, namely how the progressive distancing of humans from the linguistic or mentally denoted object was and is possible [ellipsis]. In my opinion Peirce's approach can above all for this reason be characterized as 'naturalistic'" (376). This is plausible—of course, only under the assumption (not acknowledged as such by Kappner) that something like a "protodistancing" from the world can already be ascertained in the realm of quasi-intentionality. Nevertheless, Kappner employs two different concepts of "naturalistic": a naturalistic theory of intentionality means (1...
