This lesson would, if operative, surely provide some law for the recognition, the determination in advance, of the just limits and the just extent of the situation, ANY situation, that appeals, and that yet, by the presumable, the helpful law of situations, must have its reserves as well as its promises. The storyteller considers it because it promises, and undertakes it, often, just because also making out, as he believes, where the promise conveniently drops. The promise, for instance, of the case I have just named, the case of the account to be taken, in a circle of free talk, of a new and innocent, a wholly unacclimatised presence, as to which such accommodations have never had to come up, might well have appeared as limited as it was lively; and if these pages were not before us to register my illusion I should never have made a braver claim for it. They themselves admonish me, however, in fifty interesting ways, and they especially emphasise that truth of the vanity of the a priori test of what an idee-mere may have to give. The truth is that what a happy thought has to give depends immensely on the general turn of the mind capable of it, and on the fact that its loyal entertainer, cultivating fondly its possible relations and extensions, the bright efflorescence latent in it, but having to take other things in their order too, is terribly at the mercy of his mind. That organ has only to exhale, in its degree, a fostering tropic air in order to produce complications almost beyond reckoning. The trap laid for his superficial convenience resides in the fact that, though the relations of a human figure or a social occurrence are what make such objects interesting, they also make them, to the same tune, difficult to isolate, to surround with the sharp black line, to frame in the square, the circle, the charming oval, that helps any arrangement of objects to become a picture. The storyteller has but to have been condemned by nature to a liberally amused and beguiled, a richly sophisticated, view of relations and a fine inquisitive speculative sense for them, to find himself at moments flounder in a deep warm jungle. These are the moments at which he recalls ruefully that the great merit of such and such a small case, the merit for his particular advised use, had been precisely in the smallness.
