Anyhow, as has been said, psycho-analysis depends in practice upon the interpretation of dreams. I do not know whether making masses of people, chiefly children, confess their dreams, would lead to a great output of literature; though it would certainly lead, if I know anything of human nature, to a glorious output of lies. There is something touching in the inhuman innocence of the psychologist, who is already talking of the scientific exactitude of results reached by the one particular sort of evidence that cannot conceivably be checked or tested in any way whatever. But, as Mr. Beresford truly says, the general notion of finding signs in dreams is as old as the world; but even the special theory of it is older than many seem to suppose. Indeed, it is not only old, but obvious; and was never discovered, because it was always noticed. Long before the present fashion I myself (who, heaven knows, am no psychologist) remember saying that as there is truth in all popular traditions, there is truth in the popular saying that dreams go by the rule of contraries. That is, that a man does often think at night about the very things he does not think by day. But the popular saying had in it a certain virtue never found in the anti-popular sciences of our day. Popular superstition has one enormous element of sanity; it is never serious. We talk of ages like the mediæval as the ages of faith; but it would be quite as true a tribute to call them the ages of doubt; of a healthy doubt, and even a healthy derision. There was always something more or less consciously grotesque about an old ghost story. There was fun mixed with the fear; and the yokels knew too much about turnips not occasionally to think of turnip-ghosts. There is no
