In the following review, DeWitt states that The Large Scale Structure of Space-Time is a masterpiece but laments that it is primarily for mathematicians and not physicists.

Ask a prospective graduate student in theoretical physics what area he hopes to work in, and the chances today are better than 50-50 that he will reply "gravitation theory." This has caused problems for some physics departments, but it shows where the action is—or at least where many students think the action is. This prejudiced reviewer happens to think the students are right—in that the theory of gravity poses some of the most challenging conceptual problems in physics, problems that touch the foundations of nearly all physical theories. The students are simply expressing a gut awareness of the fact.

The theoretical framework for gravitational research has remained unaltered for...
