In "Lord of the Flies" by William Golding, Ralph experiences fear in several instances throughout the novel. One notable moment occurs in Chapter 9, titled "A View to a Death." In this chapter, Ralph grapples with the realization of the loss of order and civility among the boys, particularly as they descend into savagery. He feels a sense of fear and anxiety as he grapples with the chaos that has emerged on the island.
Another poignant moment of Ralph's fear can be found in Chapter 7, where he reflects on the concept of the beast and the darkness within themselves. His fear begins to manifest as he realizes that the true danger may stem from the boys themselves rather than any external creature.
If you're looking for a specific passage where Ralph articulates his fear, Chapter 9 is impactful as he confronts the chaotic environment and the reality of Simon's death, which symbolizes the total breakdown of civilization among the boys.
