Answer:
They would live more fully.
Step-by-step explanation:
Thoreau believed that if people rejected conformity, they would be able to live their lives more fully. Thoreau thought that people who cared about the opinions of others could not act independently in the ways that they wanted to. He believed that this led people to have artificial lives that only satisfied others in order to be fully accepted by society. Therefore, the rejection of this would usually mean that their lives would be fuller and they would be happier.
