Originally published in 1936, the author investigates the working of the mind in various types of experiences, showing how sense and thought, volition and cognition, practice and theory, work together, as well in secular as in religious experiences; that in each type of experience reality presents itself, but that while secular experiences are partial, religious experiences are whole experiences. The book discusses the love of God, the conception of God as law, the relation between the transcendent and the immanent, and concludes by showing that the conception of the Absolute is inherent in one type of Christianity.
