Hope Without Optimism explores the philosophical and political meaning of hope and distinguishes it from simple optimism, cheerfulness, wishful thinking, or belief in inevitable progress. Eagleton argues that genuine hope is grounded in realism and can exist even in situations marked by uncertainty, failure, or suffering.

Drawing on thinkers such as Thomas Aquinas, Søren Kierkegaard, Karl Marx, and Ernst Bloch, the book examines how hope has been understood throughout history. Eagleton contends that authentic hope requires commitment, self-discipline, and a willingness to confront reality without surrendering to despair.

The work contributes to debates in ethics, political philosophy, religion, and cultural theory, making it valuable for students and scholars interested in contemporary social and political thought
