In this book, Russell explores the relationship between sense-data and physics, challenging the traditional view that sense-data are the fundamental entities in the universe. He argues that sense-data are not directly observable and cannot be reduced to physical objects. Instead, he proposes that sense-data are a product of the mind's organization of sensory information. Russell contends that the mind organizes sensory data into a coherent picture of the world, which he calls "the external world." He concludes that the external world is not directly observable and cannot be reduced to physical objects.
