The scientist is first of all a person, set in the framework of family and society. The problems arising from his own make-up, and from the current social scene with its special stresses, will often bulk much larger in his life than anything concerned with science. However, there are some aspects of a scientist's life that mould his general approach to Christ, whether he is aware of them or not. The work of the physical scientist, for instance, is concerned with nature, regarded as a closed system—not with God, nor even with human persons as persons. He abstracts from the Cause of nature, and from human causes, and concentrates on the relations between natural facts. This, again, commits him to an interest in the minutiae of sense knowledge which would not be in place in other studies. Philosophers indeed are interested in nature, as well as scientists, but from a different point of view; they ask different questions about nature.
