A shorter form of this review might be appearing in The Psychologist at some point, but I thought I’d post the whole thing here so that books on consciousness can fill some stockings this Christmas…
At the beginning of The Ravenous Brain, Daniel Bor reminds us “There is nothing more important to us than our own awareness”. Western society’s focus on brain, rather than cardiac, death as the natural endpoint to a meaningful life is testament to this assertion.
But only 20 years ago, consciousness science was regarded as a fringe endeavour. Now, particularly in the UK, consciousness is going mainstream, spearheaded by the Sackler Center for Consciousness Science at the Universtiy of Sussex, where Bor is based. Of course, in varying degrees, all psychologists study consciousness: attention and working memory are core components of high-level conscious function. But only recently has a deeper question been tackled: how might these functions come together to underpin awareness? Why are humans blessed with a rich, private consciousness that might not be present in other animals? And how should we tackle the all-too-frequent disorders and distortions of consciousness in neuropsychiatric disorders?
With infectious enthusiasm, Bor takes us on a tour of the latest research into how the brain generates consciousness. His scope is broad, ranging from experiments on aneasthesia and subliminal priming, to our sense of self and progress on communicating with patients in a vegetative state. One of the most difficult questions in the field is addressing what consciousness is for. Circular answers often result: if language is usually associated with consciousness, for instance, than maybe consciousness is for producing language. Bor’s answer is that consciousness is for innovation, and dealing with novelty. Again, I am not convinced that this proposal completely slips the bonds of circularity – is innovation possible without awareness? – but it opens up new avenues for future research.
This is an accessible, engaging account from a practitioner who is well aware of the messy reality of science. Bor is that rare combination of working scientist, story-teller and lucid explainer. The Ravenous Brain reads as a dispatch from a foreign country engaged in a revolution – one that is far from over.
