How do the pre-occupations of Ralph and Jack differ from each other?

Freed from adult authority and the mores of society, Ralph plays in the beach naked, a practice that at the time of Golding's writing was commonly associated with pre-industrial cultures believed to be "uncivilized" or "savage." Yet if Ralph's nudity is an uncivilized practice, it is also a reference to another popular conception of pre-civilized life, that of the Garden of Eden. Ralph does not panic over the children's abandonment on the island, but he approaches it as a paradise in which he can play happily. The reader, aware of the outcome of the Biblical Eden, should treat the boys' "paradise" with similar skepticism. Like Eden, the island paradise will collapse; the questions are how and why.

Golding idealizes Ralph from the beginning, lavishing praise on his physical beauty. In the island sun he immediately achieves a golden hue, a physical manifestation of his winning charisma. Ralph's value is not intellectual; importantly, he behaves somewhat childishly in his first encounter with Piggy. Still, Golding suggests that Ralph has a gravity and maturity beyond his years. He is a natural leader, a quality that the other boys immediately recognize when they vote him leader.

Piggy is immediately established as the intellectual of the group. Although he is physically inept, clumsy, and asthmatic, he has a rational mind and the best grasp of their situation. It is his knowledge of the conch shell that allows Ralph to summon the rest of the boys together and he who shows the most concern for some sort of established order in meetings and in day-to-day life. He has a particular interest in names, immediately asking Ralph for his and wishing that Ralph would reciprocate the question, as well as insisting that a list of names be taken when the boys assemble. This emphasis on naming is one of the first indications of the imposition of an ordered society on the island (it also recalls the naming of the animals in Genesis). For Piggy, names not only facilitate organization and communication but also mark one's position within a social hierarchy. It is significant that Piggy is forced by the others to keep his despised nickname from home, which re-inscribes his inferior social status from the Home Counties in the new dynamic of the island. We may also note that Piggy's name symbolically connects him to the pigs on the island, which in subsequent chapters become the targets of many of the boys' unrestrained violent impulses. As the boys turn their rage against the pigs, Golding foreshadows Piggy's own murder at the close of the novel.
