"Ralph wept for...the fallthrough the air of the true, wise firend called Piggy," (pg. 202).
"'...I'll give the conch to the next person to speak...And he won't be interrupted!..We'll have rules!..Lots of rules!'" (pg. 33).
"'He came-disguised...So watch; and be careful," (pg. 160).
"'I cut the pig's throat' said Jack, proudly, and yet twitched as he said it," (pg. 69).
"'Fancy thinking the Beast was something you could hunt and kill!" (pg. 143).
"'You know perfectly well you'll only meet me down there-so don't try to escape!'" (pg. 143).
"'My poor, misguided child, do you think you know better than I do?" (pg. 143).
The conflict of good versus evil is shown through Simon, good, versus the Lord of the Flies, evil.
Before the conch is broken, it is what holds together Ralph's loosening connection to society. Once it is destroyed, the boys go completely savage, leaving order and civilization to be nothing but an afterthought.
"The breaking of the conch...lay over the island like a vapor...These painted savages would go further and further," (pg. 184).
"Roger gathered a handful of stones and began to throw them...Roger's arm was conditioned by civilization..." (pg. 62).
An overall theme is descent from civilization. When the boys first arrive, they try to form a government to remain order. The longer they are on the island, the more they strayed from this order, and the more savage they became.
"High overhead, Roger, with a sense of delirious abandonment, leaned all his weight on the lever." (pg. 180).
