I am about 50 pages into McGilchrist’s latest book, The Matter With Things: Our Brains, Our Delusions, and the Unmaking of the World. He is expanding upon the hemispheric thinking he so eloquently described in his book The Master and His Emissary.* Much of our modern thought is dominated by left mode** processing, which is thought to be logical, linear, and reasonable, but it is poor at appreciating the big picture.
McGilchrist writes, “The left hemisphere is aware of much less of what surrounds it–‘sees less,’ in all senses, than the right. It is less tolerant of ambiguity and tends towards exclusive ‘either/or’ thinking; the right hemisphere is more inclusive, inclined to ‘both/and’ thinking” (p. 44).
The implications for this thinking seem relatively obvious in much of western thought and, by extension, western (primarily evangelical) theology. As good as the left hemisphere is at analyzing details, it is exquisitely unaware of what it does NOT know, which is problematic. The same is true of much of intellectual and theological certainty.
*Most of the pop-psychological literature and thinking about hemispheric (left brain/right brain) differences is, frankly, BS. However, McGilchrist is no pop psychologist and has spent a lifetime exploring the science behind hemispheric asymmetry and the implications.
**I prefer the term “left-mode” to “left-hemisphere” because it seems to me that it is the processes, rather than the anatomy, that matter.
