The cognitive mind-brain is haunted by the ghost of consciousness. Cognitive science must face this ghost, since consciousness is perhaps the most important mental phenomenon: it forms a seemingly united, multimodal phenomenological world around the subject who experiences this world from a certain point of view. Many current approaches to consciousness fail to illuminate the nature of this “experienced world”. Some philosophers want to eliminate consciousness from science for good, others build theories in which the concept of consciousness is distorted beyond recognition. I argue that elimination and Daniel Dennett's “multiple drafts” model do not offer genuine explanations for consciousness. However, certain empirically-based approaches to consciousness succeed in exorcising its ghostly reputation and, at the same time, in preserving the experienced world of consciousness as an important explanandum.

The Character of Mind provides a sweeping and accessible general introduction to the philosophy of mind. Colin McGinn covers all of the main topics--the mind-body problem, the nature of acquaintance, the relation between thought and language, agency, and the self.In particular, McGinn addresses the issue of consciousness, and the difficulty of combining the two very different perspectives on the mind that arise from introspection and from the observation of other people. This second edition has been updated with three new cutting-edge chapters on consciousness, content, and cognitive science to make it the reader of choice on this vital topic.

I claim that consciousness, just as thought or action, is only to be found at the personal level of explanation. Dennett's account is often taken to be at odds with this view, as it is seen as explicating consciousness in terms of sub-personal processes. Against this reading, and especially as it is developed by John McDowell, I argue that Dennett's work is best understood as maintaining a sharp personal/sub-personal distinction. To see this, however, we need to understand better what content ascription at the sub-personal level actually means. When we do we can see how Dennett presents both a philosophical account of consciousness and informed empirical speculation on the nature of its sub-personal underpinnings. Consciousness is a product of certain capacities that are intelligible only at the personal level, capacities that are neither present at the sub-personal level of brain mechanism nor present in 'sub-persons', e.g. some, if not all, non-human animals.

In "Consciousness Explained," Dennett (1991) denies that split-brain humans have double consciousness: he describes the experiments as "anecdotal." In attempting to replace the Cartesian Theatre of the Mind" with his own "Multiple Drafts" view of consciousness, Dennett rejects the notion of the mind as a countable thing in favour of its being a mere "abstraction." His criticisms of the standard interpretation of the split-brain data are analyzed here and each is found to be open to objections. There exist people who have survived left ["dominant"] cerebral hemispherectomy; by Dennett's criteria, they would not have minds.
