Final answer:
Jonas's new feelings in 'The Giver' lead him to become more empathetic, question his society's restrictions, and ultimately feel isolated but enlightened about life's possibilities.
Step-by-step explanation:
The question about how Jonas's new, heightened feelings affect his life likely refers to his experiences in the novel The Giver, where Jonas begins to experience real emotions after being exposed to the memories of the past. These new feelings significantly impact Jonas's life by making him more empathetic and aware of the lack of choice within his community.
As a result, Jonas begins to question the society's rules and the notion of sameness that has been enforced, leading him to feel isolated but also enlightening him about the possibilities of life beyond the community's restrictions. Much like the reference provided, Jonas could either succumb to the misery of knowing what others lack—leading to cognitive dissonance—or he could change his beliefs and attitudes to align with his new understanding of emotions and depth of experience.
