In the novel "1Q84" by Haruki Murakami, the statement about the ego suggests that once a person develops a sense of self, they are confronted with the complexities of morality. This implies that with self-awareness comes the responsibility to navigate ethical dilemmas and societal expectations. The development of the ego marks a transition into a world that demands accountability and moral reasoning.

This idea reflects a broader philosophical inquiry into the nature of human identity and ethical living. The birth of the ego signifies not just individual consciousness but also the onset of moral judgment, leading individuals to consider their actions and their implications on others. Therefore, the struggle with morality becomes an integral part of the human experience, tangled with the very essence of what it means to be self-aware in society.
