Core claims

McGilchrist’s hemispheric model is not a neuroscience of lateralization but an ontological argument: the right hemisphere’s mode of attending constitutes a prior world that the left hemisphere’s abstractions parasitically depend upon and systematically betray.
The book’s title parable—a wise master who delegates to an emissary who then usurps the throne—is a civilizational diagnosis identical in structure to Hillman’s claim that ego consciousness has become a “delusional system,” but McGilchrist grounds it in neuroanatomy rather than mythology.
McGilchrist’s account of the left hemisphere’s self-referential closure provides the most rigorous materialist explanation for what depth psychology has always called the loss of soul: the foreclosure of metaphor, image, body, and the betweenness where psyche actually lives.

How does McGilchrist’s account of the left hemisphere’s self-referential closure compare to Hillman’s diagnosis in Re-Visioning Psychology that “ego has become a delusional system,” and what does each thinker propose as the corrective?
In what ways does Peterson’s concept of the “abolished Middle Voice” in The Iron Thūmos map onto McGilchrist’s hemispheric model, particularly regarding the right hemisphere’s capacity for participatory knowing that is neither active mastery nor passive collapse?
How might McGilchrist’s neurological case for the primacy of the right hemisphere’s metaphorical attention reshape Hillman’s claim in Archetypal Psychology: A Brief Account that “soul-as-metaphor” is the psyche’s fundamental mode of logos rather than a figure of speech?
