The pendulum of human destiny has oscillated between nature and nurture for centuries, often fueled by ideological biases. However, recent breakthroughs in developmental biology, genomics, epigenetics, and neuronal plasticity have blurred the lines between these two opposing views. Despite this, the media continues to sensationalize the discovery of genes linked to specific behaviors, and the field of behavioral genetics is increasingly encroaching on the social sciences, claiming to uncover the heritability of traits like religiosity and political affiliation. These developments pose significant threats to our understanding of human freedom and moral responsibility, with far-reaching implications for social harmony, the legal system, and religious beliefs. In this book, Denis Alexander delves into these challenges, ultimately concluding that true free will, influenced by genetic variation, arises from a holistic understanding of human personhood grounded in contemporary biology. He argues that this perspective aligns with a Christian view of human nature and moral responsibility, offering a more nuanced and realistic approach to understanding human flourishing.
