An insightful and probing exploration of the contradiction between humans' enormous capacity for hatred and their evolutionary development as a social species

Why We Hate tackles a pressing issue of both longstanding interest and fresh relevance: why a social species like Homo sapiens should nevertheless be so hateful to itself. We go to war and are prejudiced against our fellow human beings. We discriminate on the basis of nationality, class, race, sexual orientation, religion, and gender. Why are humans at once so social and so hateful to each other? In this book, Michael Ruse looks at scientific understandings of human hatred, particularly Darwinian evolutionary theory.

Combining rigorous argument with an engaging and accessible style, Ruse makes frequent use of historical examples, examining the history of two World Wars, and the US offensive against Iraq. He also gives many pertinent and up-to-date examples of prejudice, including the significance of Brexit and the systemic racism that lead to the Black Lives Matter movement. Ruse pays special attention to egregious cases of hatred, such as the treatment of Jews by the Third Reich, and to pressing contemporary issues, including the status of women. Ruse concludes with constructive suggestions for ways in which we might reconcile the contradictory aspects of our nature.
