Represents the fall of man

To understand why Piggy's fall is emphasized, we need to analyze the novel "Lord of the Flies" by William Golding. One way to do this is by consulting detailed analysis and summaries, such as the one provided in the link you shared from SparkNotes.

When reading the novel, the emphasis on Piggy's fall can be understood in a few different ways. One reason is that Piggy serves as a symbol of civilization, rationality, and intellectualism. His glasses, in particular, act as a symbol of science and knowledge. By emphasizing Piggy's fall, the author highlights the theme of the decline of civilization and the triumph of savagery.

Moreover, Piggy's fall is also noteworthy because it represents the loss of sanity and humanity on the island. As the story progresses, the boys become increasingly violent and lose their grip on morality. Piggy's death marks a turning point, demonstrating how far the boys have descended into savagery.

To delve deeper into the significance of Piggy's fall and explore other themes in the novel, I recommend engaging with the SparkNotes analysis and summaries you shared. Reading the novel itself is also a valuable way to gain a comprehensive understanding of why Piggy's fall is emphasized in "Lord of the Flies."
