Throughout the story, Dreiser views his older brother Paul as an artist and a dreamer. The story ends with Paul dying after falling into a deep depression and developing anemia. Perhaps through these lines Dreiser is trying to say that his brother is finally at peace, and human life is just a fleeting dream. He could also be saying that he refuses to grieve over a life like Paul’s, which was filled with beauty and warmth. He would rather celebrate it. So he asks readers whether we should mourn losing loved ones or rejoice over the lives they lived.
