 In early 1912, Royce suffered a stroke. During his recovery, he continued to explore the philosophy of religion outlined in the Sources, with an eye toward adapting these ideas specifically to Christianity. He also returned to Peirce’s writings, seeking the solution to certain nagging problems in his own metaphysics. He found in Peirce’s semeiotic, or theory of signs, the technical tools he needed to address both issues at once. The Problem of Christianity presents, in place of the earlier Absolute Knower, the concept of an infinite community of interpretation guided by a shared spirit of truth-seeking. This Universal Community, which constitutes reality, develops greater understanding over time through its members’ continual development of the meaning of signs. Within this framework Royce endeavored to reconcile and explain many key Christian doctrines and experiences.
