Before going further and theorizing about this case, let us once more state the matter precisely. I know that the reader may straightway and quite legitimately deny the value of anecdotes of this kind. He will say that we have to do with a neurotic who has drawn upon her imagination for all the elements that give a dramatic setting to the story and surround with a halo of mystery a sad but commonplace domestic accident. This is quite possible; and it is perfectly allowable to dismiss the case. But it is none the less true that, by thus deliberately rejecting everything that does not bear the stamp of mathematical or judicial certainty, we risk losing, as we go along, most of the opportunities or clues which the great riddle of this world offers us in its moments of inattention or graciousness. At the beginning of an enquiry we must know how to content ourselves with little. For the incident in question to be convincing, previous evidence in writing, more or less official statements, would be required, whereas we have only the declarations of the husband, a neighbour and a sister. This is insufficient, I agree; but we must at the same time confess that the circumstances are hardly favourable to obtaining the proofs which we demand. Those who receive warnings of this kind either believe in them or do not believe in them. If they believe in them, it is quite natural that they should not think first of all of the scientific interest of their trouble, or of putting down in writing and thus authenticating its premonitory symptoms and gradual evolution. If they do not believe in them, it is no less natural that they should not proceed to speak or take notice of inanities of which they do not recognize the value until after they have lost the opportunity of supplying convincing proofs of them. Also, do not forget that the little story in question is selected from among a hundred others, which in their turn are equally indecisive, but which, repeating the same facts and the same tendencies with a strange persistency, end by weakening the most inveterate distrust. 15
