Scepticism and Animal Faith

George Santayana's "Scepticism and Animal Faith" is a pivotal work that serves as a critical introduction to his monumental four-volume "Realms of Being." Published in 1923, this book marks a significant evolution in Santayana's philosophical thought, elevating his stature through enhanced theoretical precision and coherence. At its heart, the text explores the radical implications of scepticism, pushing it to its ultimate conclusion where nothing truly 'given' can be said to exist externally. From this ground of ultimate doubt, Santayana introduces his profound theory of 'immediately apprehended essences'—pure, timeless, and self-contained objects of intuition. He then unveils the indispensable role of 'animal faith'—a pre-rational, instinctive belief in the existence of an external world, substance, and self—as the foundational mechanism through which we construct meaning and knowledge from these essences. This work masterfully articulates how faith, not pure reason, bridges the gap between our subjective perceptions and the objective reality, making it essential for understanding the entirety of Santayana's later philosophical system.
