Samuel Lee Wolff, The Cambridge History of American Literature (1917)
“ He is at once dogmatist and mystic; he works out his theology into dualistic metaphysics, yet he knows himself to be one with God; though he philosophizes away the Freedom of the Will, and preaches Hell for sinners, yet he meditates also the Benevolence of the Deity, and is translated into mystical rhapsodies upon the divine love and upon Nature as its symbol and emanation. The primacy he gives to motivation places him with those who insist that reward and punishment must be held up before depraved mankind to keep it even outwardly decent ”
