Much of McGilchrist's approach depends on differentiating the holistic perspective from the object-oriented one. Where he pins this difference to hemispheres, others in neuroscience claim the dorsal brain specialized in "where" (holistically), while the ventral brain specializes in "what" (objects). Are both perspectives true, such that the RH had more dorsal capacity, and the LH more ventral? And, where McGilchrist makes much of case studies with hemispheric damage, what do case studies of damage to just the dorsal, or just the ventral, show?

My concern here is that in internalizing the RH v LH McGilchrist view, the natural thing is to take it as a metaphor of two sides either in opposition or coordination; whereas if we internalize a dorsal v ventral view of how our holistic sense relates to our sense of objects, the metaphor is of levels rather than sides, and there's less of a temptation to take the picture as being one of an inevitable competition, as if we were to each be both Cain and Able.

This is a good summary as far as it goes - that is, uncritically. But it fails to mention that none of these 11 metaphysical claims follow at all from McGilchrist's brilliant earlier work on the hemispheres. The hemispheres tell us about how we engage with the world, but nothing about the world itself. Nor does it take into account the extreme one-sidedness of attacking materialist metaphysics as over-left-brained, but leaving traditional Platonism practically untouched. I'm a great fan of 'The Master and his Emissary', which has greatly influenced my own work, but this metaphysical development is profoundly equivocal: it wrongly assumes that a hemisphere balanced perspective somehow justifies that ultimately extreme left brain pursuit - metaphysics. It's also completely inadequate from a practical point of view. I have written an in-depth review at https://www.middlewaysociety.org/the-matter-with-the-matter-with-things/ which both Iain and Jonathan Rowson know about, but have totally ignored. They continue to promote the book in a one-sided way as though there were no issues with its relationship with the earlier work on the hemispheres, shutting down the important critical discussion that needs to take place.
