Introduction/AbstractPerhaps the philosophical thesis most commonly associated with Brentano is that intentionality is the mark of the mental. But in fact Brentano often and centrally uses also what he calls 'inner perception' to demarcate the mental. In this chapter, Ioffer a new interpretation of Brentano's conception of the interrelations among mentality, intentionality, and inner perception. According to this interpretation, Brentano took the concept of mind to be a natural--kind concept, with intentionality constituting the underlying nature of the mental and inner--perceivability serving as the concept's reference--fixer.
Intentionality as the Mark of the Mental: Problems with the Orthodox InterpretationBrentano's (1874) Psychology from an Empirical Standpoint is an attempt to provide systematic conceptual and methodological foundations for the scientific study of mind. The first order of business for such an exercise is to offer a sound and principled demarcation of the relevant domain of phenomena. Brentano addresses this task in the first chapter of Book II of the Psychology. There are two problems with this interpretation, however. The first and most obvious is that in the chapter of the Psychology dedicated to the demarcation issue, Brentano endorses no fewer than six ways of drawing the mental/physical distinction. Intentionality is only one of them -the third he considers. In what sense, then, is intentionality the mark (rather than just a mark) of the mental? The others include:(M1) All and only mental phenomena are either presentations or based on presentations. 2 (M2) All and only mental phenomena are not spatially extended. 3 (M4) All and only mental phenomena are objects of inner perception. 4 (M4')All and only mental phenomena are objects of perception in the success sense of the term (Wahrnehmung). 5 (M5) All and only mental phenomena are not only phenomenally but also noumenally real (they are not only appearances but also realities). 6 (M6) All and only mental phenomena necessarily appear to us as unities. 7 I will discuss some of these more fully in §3. For now, what is important to note is that intentionality is neither the first nor the last of the marks discussed by Brentano, and he does not discuss it at any special length. 4 My goal in this chapter is to present an interpretation of Brentano's view that answers these questions. I will try to show that Brentano's view is not only stable but also quite plausible. In §2, I lay out my interpretation without argument. In § §3--4, I make a case for the interpretation's assignment of theoretical roles to intentionality and inner--perceivability (respectively).
The Concept of Mind: Reference-Fixing and Underlying NatureThe tension between intentionality and inner--perceivability as potential signatures of the mental is arguably a manifestation of a deeper tension that is something of a recurring theme in the philosophy of mind. This is the tension between metaphysical and epistemological ways of conceiving of the mental domain. There are good...
