The Master and His Emissary

Knowledge Graph: The Master and His Emissary (Iain McGilchrist, 2009)

Editorial spotlight: ↑ two ways of attending — not two sets of functions

Concepts

• Master and Emissary metaphor (importance 5): The right hemisphere is the Master with broad wisdom; the left is the Emissary sent to accomplish specific tasks but who has forgotten its subordinate role.. Source: (from training memory of book).
• RH broad vigilant attention (importance 4): Right hemisphere attention is open, sustained, global — watching for the unexpected, attending to context and the whole.. Source: (from training memory of book).
• LH narrow focused attention (importance 4): Left hemisphere attention is narrow, sharply focused, selective — grasping and manipulating specific items while ignoring context.. Source: (from training memory of book).
• RH implicit embodied knowledge (importance 4): The right hemisphere deals in implicit, embodied, context-dependent understanding — the kind that resists explicit formulation.. Source: (from training memory of book).
• LH explicit propositional knowledge (importance 4): The left hemisphere favors explicit, language-mediated, context-independent propositions and procedures.. Source: (from training memory of book).
• RH world as living process (importance 4): The right hemisphere experiences the world as alive, flowing, interconnected — a place of beings and becoming.. Source: (from training memory of book).
• LH world as mechanism (importance 4): The left hemisphere reduces the world to static categories, fixed entities, mechanical parts — things to be manipulated.. Source: (from training memory of book).
• RH world of betweenness (importance 4): The right hemisphere knows the world as relational, contextual, existing in the spaces between — not as isolated objects.. Source: (from training memory of book).
• McGilchrist's reciprocal feedback (importance 4): The manner of our attention shapes what we find; left-hemisphere attention creates a left-hemisphere world, reinforcing itself.. Source: (from training memory of book).
• RH embodied being-in-world (importance 4): The right hemisphere knows us as embodied beings embedded in a living world, not disembodied minds observing mechanism.. Source: (from training memory of book).
