What revelations about joy and happiness does Equality 7-2521 have?

Equality does not understand his new, simple life, but forgets his questions as he watches the Golden One and her beauty as she walks through the forest. However, as they travel in silence, he continues to wonder about the truth of whether solitude is truly evil. He notices that although he has been taught to find joy only in working for others, he was only tired when he did so and only now finds joy as he lives for himself, and he wonders about where their thinking about morality went wrong.
