SECTION II.—INTERNAL CRITICISM
CHAPTER VI
INTERPRETATIVE CRITICISM (HERMENEUTIC)
I. When a zoologist describes the form and situation of a muscle, when a physiologist gives the curve of a movement, we are able to accept their results without reserve, because we know by what method, by what instruments, by what system of notation they have obtained them.[128] But when Tacitus says of the Germans, Arva per annos mutant, we do not know beforehand whether he took the right method to inform himself, nor even in what sense he used the words arva and mutant; to ascertain this a preliminary operation is required.[129] This operation is internal criticism.
The object of criticism is to discover what in a document may be accepted as true. Now the document is only the final result of a long series of operations, on the details of which the author gives us no information. He had to observe or collect facts, to frame sentences, to write down words; and these operations, which are perfectly distinct one from another, may not all have been performed with the same accuracy. It is therefore necessary to analyse the product of the author's labour in order to distinguish which operations have been incorrectly performed, and reject their results. Analysis is thus necessary to criticism; all criticism begins with analysis.
In order to be logically complete, the analysis ought to reconstruct all the operations which the author must have performed, and to examine them one by one, to see whether each has been performed correctly. It would be necessary to pass in review all the successive acts by which the document was produced, from the moment when the author observed the fact which is its subject up to the movements of his hand by which he traced the letters of the document; or, rather, it would be necessary to proceed in the opposite direction, step by step, from the movements of the hand back to the observation. This method would be so long and so tedious that no one would ever have the time or the patience to apply it.
Internal criticism is not, like external criticism, an instrument used for the mere pleasure of using it;[130] it yields no immediate satisfaction, because it does not definitively solve any problem. It is only applied because it is necessary, and its use is restricted to a bare minimum. The most exacting historian is satisfied with an abridged method which concentrates all the operations into two groups: (1) the analysis of the contents of the document, and the positive interpretative criticism which is necessary for ascertaining what the author meant; (2) the analysis of the conditions under which the document was produced, and its negative criticism, necessary for the verification of the author's statements. This twofold division of the labour of criticism is, moreover, only employed by a select few. The natural tendency, even of historians who work methodically, is to read the text with the object of extracting information directly from it, without any thought of first ascertaining what exactly was in the author's mind.[131] This procedure is excusable at most in the case of nineteenth-century documents, written by men whose language and mode of thought are familiar to us, and then only when there is not more than one possible interpretation. It becomes dangerous as soon as the author's habits of language or thought begin to differ from those of the historian who reads him, or when the meaning of the text is not obvious and indisputable. Whoever, in reading a text, is not exclusively occupied with the effort to understand it, is sure to read impressions of his own into it; he is struck by phrases or words in the document which correspond to his own ideas, or agree with his own a priori notion of the facts; unconsciously he detaches these phrases or words, and forms out of them an imaginary text which he puts in the place of the real text of the author.[132]
II. Here, as always in history, method consists in repressing the first impulse. It is necessary to be penetrated by the principle, sufficiently obvious but often forgotten, that a document only contains the ideas of the man who wrote it, and to make it a rule to begin by understanding the text by itself, before asking what can be extracted from it for the purposes of history. We thus arrive at this general rule of method: the study of every document should begin with an analysis of its contents, made with the sole aim of determining the real meaning of the author.
This analysis is a preliminary operation, distinct and independent. Experience here, as in the tasks of critical scholarship,[133] has decided in favour of the system of slips. Each slip will contain the analysis of a document, of a separate part of a document, or of an episode in a narrative; the analysis ought to indicate not only the general sense of the text, but also, as far as possible, the object and views of the author. It will be well to reproduce verbally any expressions which may seem characteristic of the author's thought. Sometimes it will be enough to have analysed the text mentally: it is not always necessary to put down in black and white the whole contents of a document; in such cases we simply enter the points of which we intend to make use. But against the ever-present danger of substituting one's personal impressions for the text there is only one real safeguard; it should be made an invariable rule never on any account to make an extract from a document, or a partial analysis of it, without having first made a comprehensive analysis[134] of it mentally, if not on paper.
To analyse a document is to discern and isolate all the ideas expressed by the author. Analysis thus reduces to interpretative criticism.
