Harold resolves to remember Jude for the stories Jude did tell—not everything Jude left unsaid. This proposes that people generally must give people the benefit of the doubt and live with the possibility that they might one day leave, disappoint, or betray them. Jude was too afraid of experiencing more hurt and betrayal, so he shut others out, and this brought him more suffering—not less. A certain degree of blind optimism, the novel suggests, is essential to surviving a world full of so much pain and suffering: life is unfair and suffering unavoidable, so it’s inevitable that we will one day experience hurt, fear, and agony. So in light of this sad truth, people must open themselves up to happiness and human connection when they get the chance, even if this makes losing loved ones all the more difficult.
