The Master and His Emissary

About

Background summary — AI-generated; not source-grounded.

The Master and His Emissary (2009) is Iain McGilchrist’s major work on brain hemisphere lateralisation and Western cultural history. The title refers to a parable: a wise master (the right hemisphere) delegates to an emissary (the left hemisphere) who, overstepping, usurps control and ruins the kingdom. McGilchrist uses this as an allegory for the trajectory of Western thought since the Renaissance — a progressive shift from embodied, contextual, relational knowledge toward abstract, certain, reductive knowledge.

The first half presents the neurological evidence for hemispheric differences; the second applies this lens to the history of Western art, philosophy, science, and culture, arguing that left-hemisphere dominance has accelerated since the Enlightenment and underlies many features of modernity that we find troubling.
