In practice we rarely need to know what an author believed, unless we are making a special study of his character. We have no direct interest in the author; he is merely the medium through which we reach the external facts he reports. The aim of criticism is to determine whether the author has reported the facts correctly. If he has given inexact information, it is indifferent whether he did so intentionally or not; to draw a distinction would complicate matters unnecessarily. There is thus little occasion to make a separate examination of an author's good faith, and we may shorten our labours by including in a single set of questions all the causes which lead to misstatement. But for the sake of clearness it will be well to discuss the questions to be asked in two separate series.

The questions in the first series will help us to inquire whether we have any reason to distrust the sincerity of a statement. We ask whether the author was in any of those situations which normally incline a man to be insincere. We must ask what these situations are, both as affecting the general composition of a document, and as affecting each particular statement. Experience supplies the answer. Every violation of truth, small or great, is due to a wish on the part of the author to produce a particular impression upon the reader. Our set of questions thus reduces to a list of the motives which may, in the general case, lead an author to violate truth. The following are the most important cases:—

(1) The author seeks to gain a practical advantage for himself; he wishes to deceive the reader of the document, in order to persuade him to an action, or to dissuade him from it; he knowingly gives false information: we then say the author has an interest in deceiving. This is the case with most official documents. Even in documents which have not been composed for a practical purpose, every interested statement has a chance of being mendacious. In order to determine which statements are to be suspected, we are to ask what can have been the general aim of the author in writing the document as a whole; and again, what can have been his particular purpose in making each of the separate statements which compose the document. But there are two natural tendencies to be resisted. The first is, to ask what interest the author could have had in lying, meaning what interest should we have had in his place; we must ask instead what interest can he have thought he had in lying, and we must look for the answer in his tastes and ideals. The other tendency is to take sole account of the individual interest of the author; we ought, however, to remember that the author may have given false information in order to serve a collective interest. This is one of the difficulties of criticism. An author is a member at one and the same time of several different groups, a family, a province, a country, a religious denomination, a political party, a class in society, whose interests often conflict; we have to discover the group in which he took most interest, and for which he worked.

(2) The author was placed in a situation which compelled him to violate truth. This happens whenever he has to draw up a document in conformity with rule or custom, while the actual circumstances are in some point or other in conflict with rule or custom; he is then obliged to state that the conditions were normal, and thus make a false declaration in respect of all the irregularities. In nearly every report of proceedings there is some slight deviation from truth as to the day, the hour, the place, the number or the names of those present. Most of us have observed, if not taken part in, some of these petty fictions. But we are too apt to forget them when we come to criticise documents relating to the past. The authentic character of the documents contributes to the illusion; we instinctively make authentic a synonym of sincere. The rigid rules which govern the composition of every authentic document seem to guarantee sincerity; they are, on the contrary, an incentive to falsify, not the main facts, but the accessory circumstances. From the fact of a person having signed a report we may infer that he agreed to it, but not that he was actually present at the time when the report mentions him as having been present.

(3) The author viewed with sympathy or antipathy a group of men (nation, party, denomination, province, city, family), or an assemblage of doctrines or institutions (religion, school of philosophy, political theory), and was led to distort facts in such a manner as to represent his friends in a favourable and his opponents in an unfavourable light. These are instances of a general bias which affects all the statements of an author, and they are so obvious that the ancients perceived them and gave them names (studium and odium); from ancient times it has been a literary commonplace for historians to protest that they have steered clear of both.

(4) The author was induced by private or collective vanity to violate truth for the purpose of exalting himself or his group. He made such statements as he thought likely to give the reader the impression that he and his possessed qualities deserving of esteem. We have therefore to inquire whether a given statement may not be influenced by vanity. But we must take care not to represent the author's vanity to ourselves as being exactly like our own vanity or that of our contemporaries. Different people are vain for different reasons; we must inquire what was our author's particular vanity; he may have lied in order to attribute to himself or his friends actions which we should consider dishonourable. Charles IX. falsely boasted of having organised the Massacre of St. Bartholomew. There is, however, a kind of vanity which is universal, and that is, the desire to appear to be a person of exalted rank playing an important part in affairs. We must, therefore, always distrust a statement which attributes to the author or his group a high place in the world.[149]

(5) The author desired to please the public, or at least to avoid shocking it. He has expressed sentiments and ideas in harmony with the morality or the fashion of his public; he has distorted facts in order to adapt them to the passions and prejudices of his time, even those which he did not share. The purest types of this kind of falsehood are found in ceremonial forms, official formulæ, declarations prescribed by etiquette, set speeches, polite phrases. The statements which come under this head are so open to suspicion that we are unable to derive from them any information about the facts stated. We are all aware of this so far as relates to the contemporary formulæ of which we see instances every day, but we often forget it in the criticism of documents, especially those belonging to an age from which few documents have come down to us. No one would think of looking for the real sentiments of a man in the assurances of respect with which he ends his letters. But people believed for a long time in the humility of certain ecclesiastical dignitaries of the middle ages, because, on the day of their election, they began by refusing an office of which they declared themselves unworthy, till at last comparison showed that this refusal was a mere conventional form. And there are still scholars who, like the Benedictines of the eighteenth century, look in the chancery-formulæ of a prince for information as to his piety or his liberality.[150]

In order to recognise these conventional declarations there are two lines of general study to be pursued: the one is directed to the author, and seeks to discover what was the public he addressed, for in one and the same country there are usually several different publics, each of which has its own code of morals or propriety; the other is directed towards the public, and seeks to determine its morals or its manners.

(6) The author endeavoured to please the public by literary artifices. He distorted facts in order to embellish them according to his own æsthetic notions. We have therefore to look for the ideal of the author or of his time, in order to be on our guard against passages distorted to suit that ideal. But without special study we may calculate on the common kinds of literary distortion. Rhetorical distortion consists in attributing to persons noble attitudes, acts, sentiments, and, above all, words: this is a natural tendency in young boys who are beginning to practise the art of composition, and in writers still in a semi-barbarous stage; it is the common defect of the mediæval chroniclers.[151] Epic distortion embellishes the narrative by adding picturesque details, speeches delivered by the persons concerned, numbers, sometimes names of persons; it is dangerous, because the precision of the details produces an illusive appearance of truth.[152] Dramatic distortion consists in grouping the facts in such a way as to enhance the dramatic effect by concentrating facts, which in reality were separate, upon a single moment, a single person, or a single group. Writing of this kind is what we call "truer than the truth." It is the most dangerous form of distortion, the form employed by artistic historians, by Herodotus, Tacitus, the Italians of the Renaissance. Lyrical distortion exaggerates the intensity of the sentiments and the emotions of the author and his friends: we should remember this when we attempt to reconstruct "the psychology" of a person.

Literary distortion does not much affect archives (though instances of it are found in most charters of the eleventh century); but it profoundly modifies all literary texts, including the narratives of historians. Now, the natural tendency is to trust writers more readily when they have talent, and to admit statements with less difficulty when they are presented in good literary form. Criticism must counteract this tendency by the application of the paradoxical rule, that the more interesting a statement is from the artistic point of view,[153] the more it ought to be suspected. We must distrust every narrative which is very picturesque or very dramatic, in which the personages assume noble attitudes or manifest great intensity of feeling.
