grammarian, to determine their value and age. The investigation of the literary sources of history has been a peculiarly German pastime. Doubtless such an investigation has been necessary. But it is exposed to the danger of trying to make bricks without straw. More often than not the materials are wanting for arriving at conclusions of solid scientific value. The results announced in such cases are due partly to the critic’s own prepossessions and postulates, partly to the imperfection of the evidence. It is easy to doubt, still easier to deny, especially where the evidence is defective, and the criticism of the literary sources of a narrative has sometimes meant an unwarrantable and unintelligent scepticism. To reverse traditional judgments, to reject external testimony, and to discover half-a-dozen authors where antiquity knew of but one, may be a proof of the critic’s ingenuity, but it does not always demonstrate his appreciation of evidence. Criticism of the literary sources of our historical knowledge is indeed necessary, and a recognition of the fact has much to do with the advance which has been made during the present century in the study of the past. But it must not be forgotten that such criticism has its weak side. Internal evidence alone is always unsatisfactory; it offers too much scope for the play of the critic’s imagination and the impression of his own idiosyncrasies upon the records of history. It resembles too much the procedure of the spider who spins his web out of himself. It is wanting in that element of comparison without which scientific truth is unattainable. To determine the age and trustworthiness of our literary authorities is doubtless of extreme importance to the historian, but unfortunately the materials for doing so are too often absent, and the fancies and assumptions of the critic are put in their place. The trustworthiness of an author, like the reality of the facts he narrates, can be adequately tested in only one way. We must be able to compare his accounts of past events with other contemporaneous records of them. Sometimes these records consist of pottery or other products of human industry which anthropology is able to interpret; often they are the far more important inscriptions which were written or engraved by the actors in the events themselves. In other words, it is to archæology that we must look for a verification or the reverse of the ancient history that has been handed down to us as well as of the credibility of its narrators. The written monuments of the ancient East which belong to the same age as the patriarchs or Moses can alone assure us whether we are to trust the narrative of the Pentateuch or to see in it a confused medley of legends the late date of which makes belief in them impossible.
