This Introduction does not pretend to offer anything to specialists. It is written for theological students, ministers, and laymen, who desire to understand the modern attitude to the Old Testament as a whole, but who either do not have the time or the inclination to follow the details on which all thorough study of it must ultimately rest. These details are intricate, often perplexing, and all but innumerable, and the student is in danger of failing to see the wood for the trees. This Introduction, therefore, concentrates attention only on the more salient features of the discussion.
