摘要

Information integration is a measure, due to Tononi and co-researchers, of the capacity for dynamic neural networks to be in informational states which are unique and indivisible [1]. This is supposed to correspond to the intuitive 'feel' of a mental state: highly discriminative and yet fundamentally integrated. Recent versions of the theory include a definition of qualia which measures the geometric contribution of individual neural structures to the overall measure [2]. In this paper we examine these approaches from two philosophical perspectives, enactivism (externalism) and phenomenal states (internalism). We suggest that a promising enactivist response is to agree with Tononi that consciousness consists in integrated information, but to argue for a radical rethink about the nature of information itself. Using Cox's theorem, we argue that information is most naturally viewed as a three-place relation, involving a Bayesian-rational subject, the subject's evidence, and the world (as brought under the subject's evolving understanding). Therefore, to have (or gain) information is to behave in a certain (Bayesian-rational) way in response to evidence. As such, information only ever belongs to whole subjects (rationally behaving agents); and information is only 'in the brain' from the point of view of a theorist seeking to explain such behaviour. Moreover, rational behaviour (and hence information) will depend on brain, body and world - embodiment matters. From a phenomenal states perspective, we examine the way that internal states of a network can be not only unique and indivisible, but also reflect this coherence as it might exist in an external world. Extending previously published material [3], we propose that two systems could both score well on traditional integration measures where one had meaningful world representing states and the other did not. A model which involves iconic learning and depiction is discussed and tested in order to show how internal states can be about the world and how measures of integration influence this process. This retains some of the structure of Tononi's integration measurements but operates within sets of states of the world as filtered by receptors and repertoires of internal states achieved by depiction. This also suggests a formalisation of qualia which does not ignore world reflecting content and relates to internal states that aid the conscious organism's ability to act appropriately in the world of which it is conscious. Thus, a common theme emerges: Tononi has good intuitions about the necessary nature of consciousness, but his is not the only theory of experience able to do justice to these key intuitions. Furthermore, Tononi's theory has an apparent weakness, in that it treats conscious 'information' as something intrinsically meaningless (i.e. without any necessary connection to the world) whereas both the approaches canvassed here naturally relate experienced information to the world.
