Ralph is the athletic, charismatic protagonist of Lord of the Flies.Elected the leader of the boys at the beginning of the novel,Ralph is the primary representative of order,civilization,and productive leadership in the novel.Piggy is a fat,shy twelve-year-old boy who has asthma;he is the only one who knows how to correctly pronounce asthma.The other boys on the island pronounce it as "ass-mar". Piggy wears "specs".
In the early parts of the novel, the fact that the boys maintain the fire is a sign that they want to be rescued and return to society. When the fire burns low or goes out, we realize that the boys have lost sight of their desire to be rescued and have accepted their savage lives on the island.
Free from the rules that adult society formerly imposed on them, the boys marooned on the island struggle with the conflicting human instincts that exist within each of them—the instinct to work toward civilization and order and the instinct to descend into savagery, violence, and chaos.
