ABSTRACT
This chapter describes three authors who have written about split-brain research and differences between the two hemispheres of the human brain. They are Jill Bolte Taylor, Iain McGilchrist and Roderick Tweedy. They come from different backgrounds and each provides fascinating in sights into the human condition but they also fail to differentiate distinct dichotomies. McGilchrist states that the right hemisphere is "more realistic about how it stands in relation to the world at large, less grandiose, and more self-aware than the left", and describes the left hemisphere (L-mind) as "ever optimistic, but unrealistic about its short-comings". In attributing these characteristics to the hemispheres, McGilchrist is making the same error as Bolte Taylor, in failing to distinguish between pre- and post-conscious processes that are unique to one hemisphere and the conscious processes in each hemisphere that comprise a mind. The dichotomy that Tweedy finds in William Blake's work, attributes to the two hemispheres is dichotomy within ways of thinking within the L-mind.
