Science, philosophy, and religion are considered as limited aspects of a given body of truth. Attention is given to careful definition of each term. Then science and philosophy are discussed as two branches of religion. Faith, reason, and revelation are mentioned with regard to the creation account. The author concludes that Christian thinkers should agree that philosophy may be understood to be the activity of right reason, and science may be said to be the knowledge of things knowable to sensory perception (direct or indirect), and these cannot be studied without reference to religion, but must serve religion which is Christian truth and life.
