1.2.1 Representation
The notions ‘representation’ and ‘representing’ are used in a relational sense as well as in a functional sense. On the one hand, they designate a two-place relation: a (representational) subject (an individual, or a person) relates to an object (a representational object, or representatum) by representing it. That is, the representationalist conception basically involves a primordial separation or distinction between subject and object, and yet a connection between them established in that the subject represents the object. By means of representation, individual aspects of the world (representational objects) are singled out and (mentally) grasped by an individual (the representing subject). The outcome of representing an object is that the subject entertains a representational state, or is in a state of representing. The function of token representational states is to represent objects as they are. As functional notions, ‘representation’ and ‘representing’ refer to the aim of token representational states, namely to disclose the representational object to the subject as it is actually constituted, that is, to deliver an accurate description of the object. If they do so, that is, if token representational states are veridical, the fulfil their function to the effect that the subject represents the object as it is. In this case, there is a representational relation holding between the token representational state in question and the respective representational object.
The representationalist theory of mind presumes that the world represented by individuals is ‘objective’. With respect to the ontology of representational objects, it is generally committed to ‘realism’ about the world ‘external’ to the subject. Although the views as to how realism ought to be further elaborated vary, realism minimally involves an ontological claim about representational objects and an epistemological claim about the way they are accessed in representing. The objects of mental representation are real in the sense that they are ontologically mind-independent. Thus, they are individuable independently of whether, in which way and from which perspective they are represented and their boundaries are identifiable by objective criteria. Further, ‘representation’ denotes a uniform phenomenon, its function is identical for different individuals. The apprehension of representational objects thus is equally perspective-independent as the objects themselves. Under favourable circumstances, mental representation delivers knowledge about the respective representational objects as they really are. The nature of representational objects remains unchanged by being represented. Both claims result from the idea that representational states can be assessed with respect to their veridicality, that is, with respect to whether they represent their objects as they are. The idea of veridicality implies that representational states and representational objects are comparable, which requires that the object represented by a particular representational state is identifiable beyond the respective state. The criteria by which any representational object is identifiable provide for the verifiability of representational states and, accordingly, must be objectively accessible.
An individual subject’s representational states interrelate according to certain principles, adding up to series, or sequences of interrelating representational states, that is, mental processes. The totality of an individual subject’s representational states in this way constitutes an interlocking structure or system, which is regarded as tantamount to, or at least partly constitutive of, the subject’s mind.
The relationship of the notions ‘representation’ and ‘intentionality’ is a matter of disagreement. Sometimes, they are used equivalently (for example, Crane (2003) and Searle (1983)), sometimes the notion ‘intentionality’ is deemed to include, but not be limited to that of representationality, that is, that intentional states contain non-representational elements (for example, Chalmers (2004)), or that there are some forms of intentionality, which do not include representational content at all.
I will use the notions ‘mental states’, ‘intentional states’ and ‘representational states’ interchangeably and sometimes use the notions ‘experiences’ and ‘experiential states’, without denying that at least some representationalist views hold that ‘the mental’ and ‘intentionality’ are not entirely analysable into representational states, and that ‘experiences’ and ‘experiential states’ involve non-representational elements, if they are not considered entirely non-representational.
1.2.1.1 The Two-Component-Model of Representational States
The ideas of perspectivity, veridicality, and mind-independence respond to the commonplace intuitions that the world appears to different people in different ways, that one can take different attitudes towards the same state of affairs, and that the world really is not always as it seems to be. This observation can be formulated like this: In every instance of representation, the world is represented from a certain perspective as being in a certain way. These considerations are unified in a conception of representational states, which lies at the core of representationalism and is shared by all its versions, the two-component model of the mind. This model extends to all kinds of representational states including perceptual experience (as far as this is representational), and particularly applies to intentional and linguistic states.
According to the representationalist view, representational states, or mental states, can be analysed into two components, a representational mode, and a representational content. The content of a representat...
