In this fourth volume of a projected six, Huxley registers his deep misgivings about the course of history in the late 1930s as the world moved toward a second global war. Many of his essays reflect his continuing interest in the conventions of popular culture as well as the philosophy of science and history, particularly as they inform developments in art and politics. But his larger concerns oscillate between empirical science and the particulars of social history, on the one hand, and his need for a grounding of absolute truth that would transcend both. His critique of politics and the prevailing ideologies of fascism and capitalism overlaps with his attempt to locate a foundational truth in a world of change and diversity. He embraced a form of political pacifism that intersected with an increasing attraction to religious quietism and mysticism. And he made a sustained effort to reconcile mystical experience with contemporary theories of physics and the philosophy of science. At their best, Huxley's essays stand among the finest examples of the genre in modern literature. "A remarkable publishing event...beautifully produced and authoritatively edited."-Jeffrey Hart.
