Piggy suggested to use the conch towhat the answer
In the novel "Lord of the Flies" by William Golding, the author has the boys find a beautiful conch shell on the beach. Piggy (always the man of ideas in the novel) thinks it would make a marvellous 'authority statement' - perhaps in the same way as a bishop's mitre or a crown. Because the conch is beautiful and unique, everyone will look at it and it will command silence and curiosity which will confer some respect on the holder. Those holding it while speaking might be able to expect some silence while they present their case. What Piggy does not foresee however, is that these symbols often only hold their power while the people are in awe of the establishment that presents it - once they no longer respect or fear that establishment, it's symbols and props can be be easily overpowered and torn down. This happens later in the book.
In the book The Lord of the Flies Piggy is well aware of the need for civilization to continue and to have some sense of order when the boys gather together. He hears different ones trying to talk at the same time. He suggests that they use the conch as a representation/symbol so that when one is holding it everyone else is quiet and that one is the allowed speaker. The others should listen to him until the individual holds the conch. Piggy does not realize that later the conch will be destroyed just as his civilized values will be destroyed by the boys.
