In chapter 8, Simon comes face-to-face with The Lord of the Flies, which is a severed pig's head jammed onto a stick in the middle of the forest. Before Simon hallucinates and speaks to The Lord of the Flies, he looks into its eyes and Golding writes,
The half-shut eyes were dim with the infinite cynicism of adult life. They assured Simon that everything was a bad business. (106)
The Lord of the Flies goes on to confirm Simon's previous conclusions about the beast on the island. The severed pig's head assures Simon that a physical creature does not exist on the island and the beast is actually the inherent evil inside each boy.
The "infinite cynicism of adult life" means that humans are inherently selfish, skeptical individuals, who are more concerned about their own well-being and interests than they are in magnanimous efforts to help others. The Lord of the Flies's cynical disposition and message that everything is "bad business" represents William Golding's beliefs about human nature. Golding believed that humans were inherently wicked, selfish beings, who act cynically in their own best interests. Later on in the chapter, Simon hallucinates and speaks to The Lord of the Flies about the true nature of the beast.
