The quote from Herman Melville's "Redburn" highlights the paradoxical nature of suffering and joy. It suggests that enduring hardships often leads to a deeper appreciation of joy once the suffering has ended. The pain experienced during difficult times can transform into a source of happiness when reflected upon, as we recognize the strength gained through those challenges.

Moreover, the remembrance of past struggles can evoke a sense of sweetness that surpasses the enjoyment of present delights. This perspective implies that the memories of overcoming difficulties enhance our capacity for joy, making us more grateful for the good times that follow. In essence, the past suffering enriches our emotional landscape, providing a complex yet profound understanding of happiness.
