The quote from Milan Kundera's "The Joke" suggests that people often fall into the trap of self-deception, holding on to two misplaced beliefs. They tend to believe in the intrinsic value of people and their actions, as well as in the necessity of addressing wrongdoings. However, Kundera argues that both of these beliefs are misguided.
According to the author, the truth lies in the idea that over time, all wrongs will fade into oblivion, and the pursuit of justice—whether through vengeance or forgiveness—will ultimately be rendered meaningless. Kundera highlights the futility of seeking redress, as time will erase the memory of past injustices, leading people to forget rather than rectify their grievances.
