Indifference is, indeed, one of the principal sources of credulity, because no one is ever credulous in the things that touch him closely and of which he treats, while on the other hand all (as is proved in daily life) are ready to lend an ear to more or less indifferent talk. Asceticism, diminishing the interest for things of the world and for history, assisted in the neglect and dispersion of books and documents, promoted credulity toward everything heard or read, unbridling the imagination, ever desirous of the wonderful and curious, to the disadvantage of discernment. It did this not only in history properly so called, but also in the science of nature or natural history, which was also indifferent to one, who possessed the ultimate truth of religion. The weak capacity for individualization noticeable in medieval historiography must be attributed to ascetism, which is usually satisfied with the general character of goodness or badness (the 'portrait' is very rare in it, as in the figurative arts of the same age), and it has even less consciousness of the historical differences of place and time, travestying persons and events in contemporary costume. It even goes so far as to compose imaginary histories and false documents, which portray the supposed type. This extends from Agnello of Ravenna, who declared that he wrote also the lives of those bishops of Ravenna about whom he possessed no information, _et credo_ (he said) _non mentitum esse,_ because, if they filled so high a past, they must of necessity have been good, charitable, zealous, and so forth, down to the false decretals of the pseudo-Isidore. We also owe to asceticism the _form of chronicle_ as its intimate cause, because, when the meaning of particular facts was neglected, it only remained to note them as they were observed or related, without any ideological connexion and with only the chronological connexion. Thus we frequently find among the historians of the Middle Ages the union (at first sight strange, yet not without logical coherence) of a grandiose history, beginning with the creation of the world and the dispersion of the races, and an arid chronicle, following the other principle and becoming ever more particular and more contingent as approach is gradually made to the times of the authors.
