How does Golding use Piggy to present ideas about people and society in Lord of the Flies?

Golding uses the theme of civilisation vs. savagery throughout the novel which is predominantly portrayed through Piggy and Jack. Piggy, like Ralph represents order and leadership, whereas Jack represents savagery and an unhealthy desire for power. Although Piggy portrays civilisation throughout the novel, Golding also presents him as naïve and immature. However, this isn’t surprising due to the young age of the boys, it is typical in the context of World War II, as teenagers, especially boys were expected to be mature past their age to fight for their country. Golding, an officer in the British army and who had participated in many battles throughout the war, portrays his novel as an allegoric microcosm of society throughout the duration of the war, with Piggy as the epitome of many of the young boys who fought.
