An idiolect, if there is such a thing, is a language that can be characterised exhaustively in terms of intrinsic properties of some single person at a time, a person whose idiolect it is at that time. The force of ‘intrinsic’ is that the characterisation ought not to turn on features of the person's wider linguistic community. Some think that this notion of an idiolect is unstable, and instead use ‘idiolect’ to describe a person's incomplete or erroneous grasp of their (...) language, where this latter is inherently social. Several important debates have featured discussion of individualistic, personal, or private languages. Some are considered in other entries (see the entries on the language of thought hypothesis, private language, and reference). This entry will concentrate on two influential and broadly idiolectal positions in the philosophy of language and linguistics: Noam Chomsky's preference for I-languages over E-languages (Section 2), and Donald Davidson's rejection of languages conceived as shared conventional structures that make communication possible (Section 3). David Lewis's claim that languages are a convention is a common target for both, and is outlined in an Appendix. The entry begins (Section 1) with some general remarks about the ontology of languages. Contents: 1. Idiolects and Language Individuation; 2.

Chimpanzee behaviour with mirrors makes it plausible that they can recognise themselves as themselves in mirrors, and so have a 'self-concept'. I defend this claim, and argue that roughly similar behaviour in pigeons, as reported, does not in fact make it equally plausible that they also have this mental capacity. But for all that it is genuine, chimpanzee self-consciousness may differ significantly from ours. I describe one possibility I believe consistent with the data, even if not very plausible: that the (...) chimpanzee is aware of itself only as a material being, and not as a subject of any psychological states. As I try to make clear, this possibility exists even if the chimpanzee has psychological states, and is aware of some of them. (shrink)

Language is at the core of the cognitive revolution that has transformed that discipline over the last forty years or so, and it is also the central paradigm for the most prominent attempt to synthesise psychology and evolutionary theory. A single and distinctively modular view of language has emerged out of both these perspectives, one that encourages a certain idealisation. Linguistic competence is uniform, independent of other cognitive capacities, and with a developmental trajectory that is largely independent of environmental input (...) (Pinker 1994; Pinker 1997). Thus language is seen as a paradigm of John Tooby and Leda Cosmides’ concept of “evoked culture”: linguistic experience serves only to select a specific item from a menu of innately available options (Tooby and Cosmides 1992). In explaining this concept, they appeal to the metaphor of a jukebox. The human genome pre-stores a set of options, and the different experiences provided by different cultures select different elements out of this option set. I think an appropriate evolutionary perspective on language substantially undercuts this idealisation and the evoked culture model of language. Variability between speakers; the sensitivity of linguistic development to environmental input; and the limits of encapsulation are not noise. They are central to the language and its evolution.

This article responds to two unresolved and crucial problems of cognitive science: (1) What is actually accomplished by functions of the nervous system that we ordinarily describe in the intentional idiom? and (2) What makes the information processing involved in these functions semantic? It is argued that, contrary to the assumptions of many cognitive theorists, the computational approach does not provide coherent answers to these problems, and that a more promising start would be to fall back on mathematical communication theory (...) and, with the help of evolutionary biology and neurophysiology, to attempt a characterization of the adaptive processes involved in visual perception. Visual representations are explained as patterns of cortical activity that are enabled to focus on objects in the changing visual environment by constantly adjusting to maintain levels of mutual information between pattern and object that are adequate for continuing perceptual control. In these terms, the answer proposed to (1) is that the intentional functions of vision are those involved in the establishment and maintenance of such representations, and to (2) that semantic features are added to the information processes of vision with the focus on objects that these representations accomplish. The article concludes with proposals for extending this account of intentionality to the higher domains of conceptualization and reason, and with speculation about how semantic information-processing might be achieved in mechanical systems.

Information is the fuel of cognition. At its most basic level, information is a matter of structures interacting under laws. The notion of information thus reflects the (relational) fact that a structure is created by the impact of another structure. The impacted structure is an encoding, in some concrete form, of the interaction with the impacting structure. Information is, essentially, the structural trace in some system of an interaction with another system; it is also, as a consequence, the structural fuel (...) which drives the impacted system's subsequent processes and behavior. Information takes various forms because the world has many levels of compositional and functional complexity, under different constraints. The key constraints that matter in the understanding of information are natural patterns of organization, or types, and systematic correlations among types, or laws. These level- sensitive constraints, in the form of types and laws, shape the very form in which information is tokened in some structure, that is, the very form in which it is encoded. As a result, the information-producing interactions bring about different sorts of structures, with various sorts of causal effects and functions, whence so many ways in which information is coded and utilized.

In his recent paper, Winch attacks a group of theories he calls cognitivism. These theories agree in holding that ‘the ability to think, both consciously and subconsciously, amounts to an ability to internally manipulate symbolic representations of that which we think about.The relevance of this attack to education is that ‘Cognitivism’ supplies plausible‐looking reasons for thinking that learning can take place without instruction, practice, memorisation or training and its prestige as a theory of learning devalues those activities within education.Its rejection (...) should therefore lead us to re‐examine our need for explicit teacher‐oriented pedagogies’.Cognitivism has led to an emphasis on autonomous learning and a consequent devaluing of the role of overt teaching, ‘the active transmission of knowledge and technique by an authoritative figure’.

A theory of the beliefs of non-human animals is not closed to us, only because we do not have beliefs of their kind. Starting from a theory of human beliefs and working on a building block model of propositional attitudes a theory of animal beliefs is viable. Such a theory is an example of the broader conception of a heterophenomenological approach to animal cognition. The theory aims at outlining the crucial differences between human and animal beliefs as well as the (...) relations between these attitudes and theories of them. By this it contributes both to a theory of human cognition and to a theory of the evolutionary origin of human cognition. The capacities of animals can thus be appreciated without making animals minor humans. Human cognition can be seen in its uniqueness without cutting the ties to its evolutionary origin. (shrink)

According to Donald Davidson, language is social in that only a person who has interacted linguistically with another could have a language. This paper is a discussion of Davidson’s argument in defence of that claim. I argue that he has not succeeded in establishing it, but that he has provided many of the materials out of which a successful argument could be built. Chief among these are the claims that some version of externalism about meaning is true, that possession of (...) a language requires possession of the concept of objectivity, and hence that the issue here concerns the identity of the external event that makes possible possession of the concept of objectivity. I end by presenting some reasons for thinking that only interpersonal linguistic interaction could play this role. (shrink)

I think recent discussions of content and reference have not paid enough attention to the role of language as a convention-governed system of communication. With this as a background theme, I explain the role of A-intensions in elucidating one important notion of content and correlative notions of reference.

According to a well-established tradition in the philosophy of language, we can understand what makes an arbitrary sound, gesture, or marking into a meaningful linguistic expression only by appealing to mental states, such as beliefs and intentions. In this paper, I explore the contrasting possibility of understanding the meaningfulness of linguistic expressions just in terms of observable linguistic behavior. Specifically, I explore the view that a type of sound becomes a meaningful linguistic expression within a group in virtue of the (...) production of that type of item becoming that group’s widespread, copied way of getting others to involve an object or relation in their activity. After discussing a preliminary version of the view, I develop it in response to some key concerns about whether it really does, as a matter of fact, eschew mental states, and about its adequacy as an account of linguistic meaning.
