It will be remarked that these recognitions are most often made by women and children--that is to say, by precisely the most impressionable persons. They show us at the same time what is the worth in law courts of such witnesses. As far as children, more especially, are concerned, their statements ought never to be invoked. Magistrates are in the habit of repeating that children do not lie. Did they possess a psychological culture a little less rudimentary than is the case they would know that, on the contrary, children invariably lie; the lie is doubtless innocent, but it is none the less a lie. It would be better to decide the fate of an accused person by the toss of a coin than, as has been so often done, by the evidence of a child. To return to the faculty of observation possessed by crowds, our conclusion is that their collective observations are as erroneous as possible, and that most often they merely represent the illusion of an individual who, by a process of contagion, has suggestioned his fellows. Facts proving that the most utter mistrust of the evidence of crowds is advisable might be multiplied to any extent. Thousands of men were present twenty-five years ago at the celebrated cavalry charge during the battle of Sedan, and yet it is impossible, in the face of the most contradictory ocular testimony, to decide by whom it was commanded. The English general, Lord Wolseley, has proved in a recent book that up to now the gravest errors of fact have been committed with regard to the most important incidents of the battle of Waterloo--facts that hundreds of witnesses had nevertheless attested.[5] [5] Do we know in the case of one single battle exactly how it took place? I am very doubtful on the point. We know who were the conquerors and the conquered, but this is probably all. What M. D'Harcourt has said with respect to the battle of Solferino, which he witnessed and in which he was personally engaged, may be applied to all battles--"The generals (informed, of course, by the evidence of hundreds of witnesses) forward their official reports; the orderly officers modify these documents and draw up a definite narrative; the chief of the staff raises objections and re-writes the whole on a fresh basis. It is carried to the Marshal, who exclaims, `You are entirely in error,' and he substitutes a fresh edition. Scarcely anything remains of the original report." M. D'Harcourt relates this fact as proof of the impossibility of establishing the truth in connection with the most striking, the best observed events.
