The preceding chapter as a whole showed the unity of man to rest upon a constant alliance between belief and affection, in order to regulate activity. Religion, by means of its source in affection, establishes and maintains harmony within us; while, by its foundation of reason, it completes and strengthens that harmony, making all subordinate to the world without us. These two fundamental conditions are necessarily combined in one in the final synthesis, which refers both of them alike to the Great Being, who is the natural center of man’s entire life.
