In recent years, the study of psychology has become more prominent as technical terms, concepts, and theories have gained prominence and acceptance among laypeople. However, the prevalence of talk about psychology has not always led to greater understanding of the discipline itself. This introductory resource for Christian students examines the field from a distinctly Christian perspective. The first section looks to the history of psychological inquiry, focusing on thinkers such as Augustine and Thomas Aquinas, the influence of the Enlightenment and Darwinism, and the development of modernist psychology. In section two, readers interact with the "great ideas" of psychology, such as the origins of morality, nature vs. nurture, the relationship between the mind and the brain, and the concept of personal identity.
