In this philosophical treatise, 19th-century British theologian Baden Powell explores the nature of truth and the relationship between empirical knowledge and metaphysical speculation. Drawing on both classical and contemporary sources, Powell argues that truth is necessarily grounded in the particularities of experience and is always subject to revision and refinement. At the same time, he insists that there are universal principles of reason and morality that are accessible to human beings through intuition and reflection. A challenging but rewarding work.
