This book explores the nature, value, and role of hope in human life under conditions of oppression. Oppression is often a threat and damage to hope, yet many members of oppressed groups, including prominent activists pursuing a more just world, find hope valuable and even essential to their personal and political lives. This book offers a unique evaluative framework for hope that captures the intrinsic value of hope for many of us, the rationality and morality of hope, and ultimately how we can hope well in the non-ideal world we share. It develops an account of the relationship between hope and anger about oppression and argues that anger tends to be accompanied by hopes for repair. When people’s hopes for repair are not realized, as is often the case for those who are oppressed, anger can evolve into bitterness: a form of unresolved anger involving a loss of hope that injustice will be sufficiently acknowledged and addressed. But even when all hope might seem lost or out of reach, faith can enable resilience in the face of oppression. Spiritual faith, faith in humanity, and moral faith are part of what motivates people to join in solidarity against injustice, through which hope can be recovered collectively. Joining with others who share one’s experiences or commitments for a better world and uniting with them in collective action can restore and strengthen hope for the future when hope might otherwise be lost.
