It is often claimed that for any item to count as representational, it must form part of a general representational scheme or framework. Many people, though by no means all, claim that the idea of representation can be captured, in part, in terms of the concept of information. Many suppose that models of representation are subject to a teleological constraint. It is common to hold that, to be regarded as genuinely representational, a representation must be decouplable from the environment. In connection with the informational constraint, the possibility of representation is closely tied to the possibility of misrepresentation. Much recent work on cognition is characterized by an augmentation of the role of action coupled with an attenuation of the role of representation. This chapter discusses the representation and the extended mind, the first horn and the second horn.
