In issuing this little book, which aims at being, within the limits assigned, as objective a presentation of the Ritschlian Theology as is possible to one who, while conscious of having benefited by its teaching, does not share the standpoint of the school, the author desires to express his thanks to the Rev. Wm. M'Gilchrist, B.D., Ardrossan, for his kindness in aiding in the revision of the proofs, and for frequent helpful suggestions.
