  A recurring theme in Norris' writings is the importance of solitude and meditation. Christianity, for Norris, was a highly personal relationship with one's God. Being a good Christian involves the opening of one's mind to a comprehension of God. “For Passion is the great Contrariety to Reason, and will draw a cloud over the brightest Mind. The quiet and sedate Soul is most fit for the Contemplation of Truth, as the calmest Weather is commonly the most serene” (Two Treatises in Treatises upon Several Subjects 353).
