In chapter 11 of Lord of the Flies, why does Ralph bother to blow the conch when calling together the small assembly?
I think Ralph wants to instill some sort of order in an otherwise chaotic environment. By blowing the conch he's modeling to the others how to follow the rules.
The conch is a symbol of order. His decision to continue using the conch is continuing the routine they have established. It takes one person to follow the rules and other people will hopefully follow the lead.
