In William Golding's "Lord of the Flies," Piggy often criticizes the other boys for their lack of order and rationality, especially as the situation on the island deteriorates. When chaos ensues, particularly symbolized by the fragility of the flower or the descent into savagery, Piggy highlights their failure to maintain civilization and reason. He frequently admonishes them for abandoning the rules and leadership they initially tried to establish, emphasizing the importance of discussion and civilized behavior. His criticisms often reflect his concern about the fragility of social order and the potential for chaos when rationality is lost.
