In Saul Bellow's novel "Herzog," the protagonist experiences a shift in perspective that leads him to believe his actions carry historical significance. This notion, albeit somewhat irrational, suggests that his personal struggles and interactions are part of a larger experiment in life and human behavior. His mindset frames the challenges he faces as pivotal, causing him to view those who oppose him as impediments to this vital undertaking.

This belief emphasizes the protagonist's turmoil and self-reflection, as he grapples with his place in the world. The fantasy of having a crucial role not only highlights his inner conflict but also reflects a broader theme of searching for meaning in life's complexities. Ultimately, it underscores how personal experiences can be tied to universal questions of purpose and significance.
