The Capacity for Evil and the Nature of Human Morality One of the foundational themes Glover examines is human nature’s dual capacity for both evil and goodness. He discusses how the 20th century exposed the depths of human cruelty—through genocide, ethnic cleansing, and war—yet also highlighted extraordinary acts of altruism and moral courage. Glover challenges simplistic notions of inherent human evil, proposing instead that morality is complex and context-dependent. 2 The Development of Human Rights A significant aspect of the century’s moral progress was the recognition and institutionalization of human rights. Glover traces how atrocities such as the Holocaust and other genocides prompted a global moral awakening, leading to the Universal Declaration of Human Rights in 1948. This shift marked a collective effort to establish moral standards that transcend national borders, emphasizing dignity, equality, and justice. The Role of Responsibility and Moral Agency Glover emphasizes the importance of individual responsibility in moral development. He explores how ordinary people can commit extraordinary acts—both evil and good—depending on circumstances, social pressures, and personal choices. The concept of moral agency becomes central, highlighting that individuals are capable of moral reflection and decision-making even in complex situations. The Impact of Technology and War Technological innovations, especially in warfare, profoundly influenced moral considerations.
