The Science of the Soul
In the English-speaking world, Christian thinkers played a fundamental role in laying the foundation for the scientific investigation of the mind. Those thinkers who equated the soul with the psyche and accorded the mind a privileged status in the overall scheme of things played a central role in shaping discourse in mental and moral philosophy and in opposing materialistic interpretations of the mind. During the late nineteenth century, research in neurophysiology, coupled with natural historians’ endorsement of the theory of organic evolution and the increasing use of experimental and quantitative methods of understanding the data of consciousness, led to the emergence of a ‘new psychology’. Although the new psychologists joined Christians in resisting efforts on the part of scientific naturalists to reduce mental phenomena to the activity of the nervous system, they insisted on eliminating ‘God-talk’ from their discipline, thereby differentiating their own preoccupations from those of religious thinkers.
