Iain McGilchrist
Iain McGilchrist is a British psychiatrist, philosopher, and author best known for his work The Master and His Emissary: The Divided Brain and the Making of the Western World (2009). His central thesis is that the two cerebral hemispheres of the brain are not specialized for different types of content (e.g., logic vs. creativity) but for different ways of attending to the world — and that the Western world has suffered a catastrophic imbalance in favor of the left hemisphere's mode of attention.
The Divided Brain
McGilchrist argues that the left and right hemispheres attend to the world in fundamentally different ways:
- Right Hemisphere — Attends to the whole, the living, the embodied, the new, the ambiguous. It grasps things in their context and sees them as unique individuals. It is the hemisphere of empathy, metaphor, and the sacred.
- Left Hemisphere — Attends to the parts, the mechanical, the abstract, the known. It re-presents what the right hemisphere has already grasped, breaking it down into categories and manipulable components. It is the hemisphere of language, analysis, and control.
The hemispheres are meant to work in partnership — the right hemisphere as the "master" who sees the whole, the left as the "emissary" who analyzes and manipulates. But in the modern West, the emissary has usurped the master.

- Gestalt Psychology-The Mechanics of the Whole — McGilchrist's account of right-hemisphere attention — holistic, contextual, grasping the whole before the parts — is the neuroscientific foundation for Gestalt psychology's claim that the whole is prior to its parts.
- Søren Kierkegaard — Kierkegaard's critique of Hegelian systematic philosophy — the claim that "existence cannot be systematized" — anticipates McGilchrist's diagnosis of left-hemisphere dominance: the attempt to reduce the living, irreducible reality of existence to abstract categories.
