"Everything we do seeds the future. No action is an empty one."
Certainly this quote proves true in Lord of the Flies. Of all the characters, Simon realizes the veracity of this statement earlier than any of the other boys. Simon has the insight to realize the potential for disaster on the island, that the boys could indeed be their own worst enemies. At one of their tribal meetings when the boys gather to discuss the 'Beast,' Simon meekly suggests "maybe it's only us" (89).
The perfect case in point is Jack. His actions from the beginning of the novel where he identifies himself and the choir boys as 'hunters' to his first kill set him forward on a path that leads to violence and murder. Simon's insight concerning the 'beast' is utterly confirmed as Jack becomes more and more engrossed in the hunt, ultimately allowing his violent dance game to culminate in the death of another boy, Simon. Jack's actions do "seed the future," in the worst possible way imaginable.
