In 1964–1965, Hans Helmut Kornhuber and Lüder Deecke achieved a scientific breakthrough with the discovery of the Bereitschaftspotential (BP), or readiness potential. In The Will and its Brain, Kornhuber and Deecke present evidence that proves we can record activity from the human brain occurring prior to our volitional movements or actions. Such preparatory activity is generated by specific brain regions, particularly by the supplementary motor area (SMA) of the frontal lobe, which lies on the inner surface of the brain between the hemispheres. The primary (precentral) motor cortex (MI) later becomes activated in preparing for action. Consequently, the authors discriminate between two components of the preparatory activity of the Bereitschaftspotential: an early SMA-generated BP1 and a late MI-derived BP2. Between BP1 and BP2, the intentional activity runs over the so-called motor loop via the basal ganglia. Kornhuber and Deecke discuss these and other brain processing systems while focusing on the concept of free will. They claim that we, indeed, have free will. It may not be absolutely free, but free in terms of degrees. We can take efforts to increase our degrees of freedom through self-improvement, but we can also lose degrees of freedom through self-mismanagement.
This overview of Christian anthropology by Hans Schwarz uniquely emphasizes three things: (1) the biblical testimony, (2) the historical unfolding of Christian anthropology through the centuries, and (3) the present affirmation of Christian anthropology in view of rival options and current scientific evidence. Schwarz begins by elucidating the special place occupied by human beings in the world, then ponders the complex issue of human freedom, and concludes by investigating humanity as a community of men and women in this world and in the world beyond. While maintaining a strong biblical orientation, Schwarz draws on a wide range of resources, including philosophy and the natural sciences, in order to map out what it means to be human. Schwarz's Human Being will interest anyone who is concerned with how in the face of fascinating scientific insights we can intelligently talk today about human sinfulness, human freedom, and human beings as children of the God who created us.
The emancipation of the natural sciences from religion was a gradual affair during the last four centuries. Initially many of the leading scientists were churchmen indicating a symbiosis between faith and reason. Due to the increasing specialization in the sciences this close connection came to an end often leading to antagonism and mutual suspicion. This book traces this historical development with its twists and turns in both Europe and North America. It depicts the major players in this story and outlines their specific contributions. The main focus is on the 19th and 20th centuries with figures such as Darwin and Hodge, but also Beecher and Abbott in the 19th century. In the 20th century the narrative starts with Karl Barth and moves all the way to Hawking and Tipler. Special attention is given to representatives from North America, Great Britain, and Germany. In conclusion important issues are presented in the present-day dialogue between theology and the natural sciences. The issue of design and fine-tuning is picked up, and advances in brain research. Finally technological issues are assessed and the status of medicine as a helpmate for life is discussed. An informative and thought-provoking book.
