Note 3 — Chapter I · THE APPROACH
Reading edition
As the theory has a vital bearing on the relative values of different strata of tradition, Mr. Robertson cannot afford to ignore it. If we apply to himself the crude principle he applies to Paul and the evangelists, to wit, that if they don’t mention a thing they don’t know it, we must assume that Mr. Robertson is still ignorant of the very elements of the problem he is professing to solve. Since he has no clear or tenable view of the documents and their relations to one another, he obviously cannot answer the historical questions they raise.3... Presumably he omits to mention it because he does not see its significance.4
