to be mentioned, we prefer to call it more precisely 'Internal Evidence of Readings'. Internal Evidence of Readings is of two kinds, which cannot be too sharply distinguished from each other; appealing respectively to Intrinsic Probability, having reference to the author, and what may be called Transcriptional Probability, having reference to the copyists. In appealing to the first, we ask what an author is likely to have written: in appealing to the second, we ask what copyists are likely to have made him seem to write. Both these kinds of evidence are alike in the strictest sense internal, since they are alike derived exclusively from comparison of the testimony delivered, no account being taken of any relative antecedent credibility of the actual witnesses.
A. 25—27. Intrinsic Probability
25. The first impulse in dealing with a variation is usually to lean on Intrinsic Probability, that is, to consider which of two readings makes the best sense, and to decide between them accordingly. The decision may be made either by an immediate and as it were intuitive judgement, or by weighing cautiously various elements which go to make up what is called sense, such as conformity to grammar and congruity to the purport of the rest of the sentence and of the larger context; to which may rightly be added congruity to the usual style of the author and to his matter in other passages. The process may take the form either of simply comparing two or more rival readings under these heads, and giving the preference to that which appears to have the advantage, or of rejecting a reading absolutely, for violation of one or more of the congruities, or of adopting a reading absolutely, for perfection of congruity.
