ABSTRACT
This chapter discusses the belief and doubt as modes of experience; and finds that they are feelings of the kind which we agreed to call "derived emotions." The Association Psychology described and explained belief as the persistence of an "inseparable association." It was said that if two "ideas" succeed one another again and again in "consciousness," they become more and more firmly linked together, until at last it is impossible for one of them to come to "consciousness" without being followed immediately by the other. Belief is, confidence on the intellectual plane; and doubt is hesitation or anxiety on the same plane of explicitly formulated propositions. Belief grows up gradually out of confidence with intellectual development, and there is no sharp line to be drawn between them. Belief in reality of other things is determined by a projection of one's own reality; and that reality is at bottom one's power of striving, of exerting an effort, of persisting toward a goal.
