In Pragmatism, William James introduces and defines the philosophical movement that judges ideas and beliefs based on their practical consequences and real-world application. Drawing from thinkers like Charles Peirce, James argues that truth is not fixed or abstract but emerges from experience and utility. Through accessible lectures, he explores how pragmatism bridges the gap between science and religion, idealism and materialism, offering a flexible approach to knowledge and belief. Rooted in American intellectual tradition, the book champions open-mindedness, pluralism, and the evolving nature of truth. James presents pragmatism as both a method of inquiry and a way of life, challenging rigid dogmas while affirming the value of human experience in shaping meaning. This groundbreaking work remains foundational in modern philosophy, influencing thought across disciplines.
