Abstract:
This paper falls into three parts. In Part 1 I give my reasons for rejecting two aspects of Horgan and Tienson's position as laid out in their book, the language of thought and belief-desire explanations of behaviour, while endorsing the connection they see between linguistic syntax and the syntax of a motor skill. In Part 2 I outline the theory that the brain consists of two input-output transformation systems consciousness whose function is (a) to categorise problematic inputs, (b) to select a response appropriate to such inputs once they have been categorised and (c) to initiate and monitor the execution of such response once selected, and the "zombie-within" whose function is (a) to identify and alert consciousness to any inputs that are problematic either because they are unexpected or because they are significant relative to the agent's current or perennial motivational concerns. In Part 3 I consider how far the properties of the two systems outlined in Part 2 can be understood in terms of the known properties of connectionist networks.

Abstract:
Cowey & Stoerig's (1995) demonstration that the phenomenon of blindsight applies to monkeys with striate cortical lesions in the same way as it does to humans with similar lesions makes it plausible to argue that the behaviour of mammals and probably that of other vertebrates is controlled by two distinct but closely interdependent and interacting systems in the brain which I shall refer to respectively as 'consciousness' and the 'sub-conscious automatic pilot or "zombie" within'. On this hypothesis, consciousness has three functions, (a) that of categorizing any input that is problematic in that it is either unexpected or significant relative to the individual's current or perennial motivational concerns, (b) that of selecting a response appropriate both to the presence of a thing of that kind and to the individual's motivational concerns with respect to it, and (c) that of monitoring the execution of that response. Conscious/phenomenal experience, on this view, is the first stage in the process whereby problematic inputs are processed by consciousness. Its function is to modify the figure-ground relations within the central representation of a problematic input until an adequate categorization is selected. The sub-conscious automatic pilot or “zombie-within” has two functions (a) that of continuously scanning the total current input and alerting consciousness to any input it identifies as problematic, (b) that of protecting consciousness from overload either by ignoring those non-problematic inputs which require no response or by responding appropriately but automatically to those for which there already exists a well practised skill or other “instinctive” response pattern.

Abstract:
There is an argument (Medlin, 1967; Place, 1988) which shows conclusively that if qualia are causally impotent we could have no possible grounds for believing that they exist. But if, as this argument shows, qualia are causally potent with respect to the descriptions we give of them, it is tolerably certain that they are causally potent in other more biologically significant respects. The empirical evidence, from studies of the effect of lesions of the striate cortex (Humphrey, 1974; Weiskrantz, 1986; Cowey and Stoerig, 1995) shows that what is missing in the absence of visual qualia is the ability to categorize sensory inputs in the visual modality. This would suggest that the function of private experience is to supply what Broadbent (1971) calls the “evidence” on which the categorization of problematic sensory inputs are based. At the same time analysis of the causal relation shows that what differentiates a causal relation from an accidental spatio-temporal conjunction is the existence of reciprocally related dispositional properties of the entities involved which combine to make it true that if one member of the conjunction, the cause, had not existed, the other, the effect, would not have existed. The possibility that qualia might be dispositional properties of experiences which, as it were, supply the invisible “glue” that sticks cause to effect in this case is examined, but finally rejected.
