『The better angels of our nature』要約

In "The Better Angels of Our Nature," Steven Pinker explores the decline of violence throughout human history, asserting that we are living in one of the most peaceful eras. Pinker uses a multidimensional framework to analyze historical trends in violence, supported by an array of statistics and psychological insights. He argues that this decline is attributable to various factors, including the rise of centralized governments, the spread of commerce, and the influence of Enlightenment values. The book is structured around a chronological examination of violence through six epochs, ranging from prehistory to modern times. Pinker contends that the evolution of human societies—marked by developments such as the establishment of rule of law, the expansion of literacy, and the growth of empathy—has significantly contributed to this decrease in violence. One of the distinctive arguments involves the concept of the “civilizing process,” which posits that as societies become more interconnected and literate, individuals grow more empathetic and less prone to violence. Pinker draws on a variety of case studies, including the reduction in homicide rates, the waning of slavery, and the decreasing prevalence of war. He also discusses psychological experiments and theories, such as the impact of cognitive biases on our perception of violence. Overall, Pinker’s analysis invites readers to reconsider their beliefs about human nature and the progress of civilization. By integrating historical data, social science, and philosophical inquiry, "The Better Angels of Our Nature" presents a provocative argument that challenges the notion of inherent human predisposition towards violence, instead highlighting the capacity for cooperation and compassion.
