Omri Boehm's 'Radical Universalism' explores the concept of universal justice, drawing inspiration from Martin Luther King Jr.'s moral stance against the Vietnam War. Boehm argues that true justice transcends group interests and requires a commitment to abstract principles, even when it means acting against one's own interests. The book critiques contemporary politics for abandoning universalism in favor of parochialism and identity-based struggles, and challenges centrists for reducing universalism to a mere matter of rights without duties.

Boehm addresses current global conflicts, including the war in Gaza, to illustrate how universal values have been eroded. He recounts his own experience of being disinvited from a Holocaust commemoration for advocating universal values, emphasizing the need to extend the vow of 'never again' beyond any single group. Throughout, Boehm draws on the philosophy of Immanuel Kant to argue that universalism demands independent moral reasoning and a refusal to blindly obey authority.

The reviewer finds Boehm's case for universalism both inspiring and urgent, suggesting that a renewed sense of duty to others could be more transformative than any radical ideology. The book is praised for its timely and invigorating challenge to the prevailing culture of self-interest and division.
