Final answer:
The actions of the boys in Lord of the Flies are primarily driven by the instinct to survive, but other factors also play a role.
Step-by-step explanation:
The actions of the boys in Lord of the Flies can be seen as primarily driven by the instinct to survive. For example, the mounting of the sow's head can be interpreted as the boys' attempt to assert dominance and establish a hierarchy for their own safety. Simon's ascent up the mountain can be seen as his desperate search for truth and understanding in order to navigate the uncertain and dangerous situation they are in.
Furthermore, the murder of Piggy can be viewed as a means for the boys to eliminate a threat and maintain their own survival. These examples, along with other key scenes in the novel, suggest that the boys' actions are indeed influenced by the instinct to survive in difficult conditions.
However, it is important to note that other factors also play a role in their actions. The boys' fear, power struggles, and the breakdown of societal norms are significant factors that contribute to their behavior. Therefore, it can be said that the boys' actions are a combination of survival instinct and other factors.
Overall, Lord of the Flies provides evidence to support the idea that human behavior is influenced by the instinct to survive. The novel explores the complexities of human nature when faced with extreme circumstances, highlighting the primal instinct to protect oneself and secure one's survival.
