What must jonas learn to do as the memories of strength and courage given to him by The Giver begins to fade? what theme does this suggest? support this question with detail@\!

Jonas must rely on his own strength and courage to handle his own psyche which includes emotions.  In the end, Jonas's respect for human life as gained through the memories allows him to understand what he must do in order to benefit the larger community. Meanwhile, the lack of memories held by the rest of the community prevents them from adjusting their own destinies wisely, so they remain terrified of change and are forced to remain in a static, stagnant existence.

what would the theme be?
