Since a fact is historical in so far as it is thought, and since nothing exists outside thought, there can be no sense whatever in the question, What are _historical facts_ and what are _non-historical facts?_ A non-historical fact would be a fact that has not been thought and would therefore be non-existent, and so far no one has yet met with a non-existent fact. A historical thought links itself to and follows another historical thought, and then another, and yet another; and however far we navigate the great sea of being, we never leave the well-defined sea of thought. But it remains to be explained how the illusion is formed that there are two orders of facts, historical and non-historical. The explanation is easy when we recollect what has been said as to the chroniclizing of history which dies as history, leaving behind it the mute traces of its life, and also as to the function of erudition or philology, which preserves these traces for the ends of culture, arranging scattered items of news, documents, and monuments in an orderly manner. News, documents, and monuments are innumerable, and to collect them all would not only be impossible, but contrary to the ends themselves of culture, which, though aided in its work by the moderate and even copious supply of such things, would be hindered and suffocated by their exuberance, not to say infinity. We consequently observe that the annotator of news transcribes some items and omits the rest; the collector of papers arranges and ties up in a bundle a certain number of them, tearing up or burning or sending to the dealer in such things a very large quantity, which forms the majority; the collector of antiques places some objects in glass cases, others in temporary safe custody, others he resolutely destroys or allows to be destroyed; if he does otherwise, he is not an intelligent collector, but a maniacal amasser, well fitted to provide (as he has provided) the comic type of the antiquarian for fiction and comedy. For this reason, not only are papers jealously collected and preserved in public archives, and lists made of them, but efforts are also made to discard those that are useless. It is for this reason that in the recensions of philologists we always hear the same song in praise of the learned man who has made a 'sober' use of documents, of blame for him who has followed a different method and included what is vain and superfluous in his volumes of annals, of selections from archives, or of collections of documents. All learned men and philologists, in fact, select, and all are advised to select. And what is the logical criterion of this selection? There is none: no logical criterion can be named that shall determine what news or what documents are or are not useful and important, just because we are here occupied with a practical and not with a scientific problem. Indeed, this lack of a logical criterion is the foundation of the sophism that tyrannizes
