Ron takes the debate over to mind vs. matter into language—which is where the mystery of mind is best revealed. He gives us a crash course in philosophy in ten minutes—and uses the colour 'red' to reveal the immense complexity in simply naming the world. The highlight though belongs to his one-year-old grandson, Levi—and he uses Levi's early experiments with words to celebrate the wonders of the mind at work through language and how we acquire it.
