critics, but all convinced upholders of supernatural revelation." But even among these Christian, evangelical, higher critics a distinction must be made between two classes. The one may be called, for want of a better name, traditional, because its adherents insist that their investigations on the line of the higher criticism have confirmed in all essentials the positions held during many centuries. It should be noted, however, that many scholars who are sometimes quoted as upholders of the traditional view are ready to make many concessions to those who believe that the traditional views are no longer tenable.[13] On the other hand is a class of critics which may be called nontraditional, critics who claim that {84} their investigations, while confirming the truth of many traditional positions, compel them in other cases to set aside the traditional views in favor of some more in accord with the facts in the case. It may be difficult to state all the causes responsible for the differences in the conclusions of these two classes of critics. However, the writings of some scholars in the former class seem to show that the authors are influenced, to some extent at least, by the fear that further concessions would affect the Christian theory of inspiration. Another cause may be found in the fact that the present generation of Old Testament scholars received its training largely at the hands of those accustomed to the traditional viewpoint; the influence of this early training manifests itself to some extent in the present attitude. A more important cause, however, is supplied by the nature of the evidence upon the basis of which these critical questions must be settled. Mathematical demonstration is impossible in very many cases. The critic must be qualified to estimate probabilities, and various degrees of probability, depending upon the nature of the grounds on which it rests. In the nature of the case, the personal element enters into the estimate of the degree of probability. What to some may appear a high degree of probability, or amount to practical certainty, may to another investigator, perhaps less familiar with {85} the facts in the case, appear of less value and lead him to reject the conclusion entirely. As long as this condition of affairs continues--and there is no reason to suppose that it ever will be otherwise--perfect agreement among critical investigators need not be expected; but a fair and thorough examination of the facts by all must be insisted upon.
