In Wallace Stegner's novel "Angle of Repose," the theme of reconciliation is emphasized through the understanding that the past is irrevocable. The characters confront their histories and the decisions that have shaped their lives, recognizing that what has transpired can no longer be changed. This realization highlights the importance of acceptance in moving forward.

The quote serves as a poignant reminder that clinging to the past can hinder personal growth and healing. By acknowledging the need to reconcile with past experiences, individuals can find peace and develop a clearer vision for their future, ultimately accepting that the only path forward lies in embracing the present and letting go of what once was.
