The Sophia Lectures with Iain McGilchrist - Lecture 1: Division and Union

Listen to this episode from The Ralston College Podcast on Spotify. This lecture, like the very essence of Ralston College’s mission, explores the profound interplay between division and union—a relationship that illuminates the nature of wholeness itself.  Dr Iain McGilchrist delves into the insight that the whole is far more than the sum of its parts; it is a dynamic synthesis, a living interplay that transcends reductionism. Drawing on analogies from music, nature, and the human brain, McGilchrist reveals the delicate harmony between separation and connection, a truth exemplified most vividly in the brain’s two hemispheres. Here, division and union are not adversaries but partners, each essential to the vitality of the other, enabling the brain to function as a unified and life-giving organ of thought and perception. Such a model reflects the very spirit of Ralston College’s aim to unify what modernity has fractured—the intellectual and the spiritual, the individual and the communal, the ancient and the urgent. The lecture also engages with the concept of emergence, a phenomenon where systems reveal qualities and capacities far beyond what their components alone could predict. Ultimately, McGilchrist’s argument aligns with the vision of this College: that division and union are not contradictory but complementary forces, driving the renewal of meaning and vitality. It is through this synthesis, through holding the tension between opposites, that true wholeness and innovation emerge—a principle as foundational to the functioning of the human brain as it is to the regeneration of our civilization.
