The ring will come back to him from the dust of death. THE PRINCIPLES OF DISGUISE It is universally admitted that Datchery was disguised. Before seeking to identify him with a character already known to us I shall give a short note on the principles and limitations of disguise. Suppose one wishes to disguise himself, how far is it possible for him to succeed? What are the limits within which success is possible? The question was very carefully discussed in the _Berliner Tageblatt_ for 15th May 1912, under the title ‘On the Psychology of Dissimulation.’ The author, Dr. Hugo Eick, uses the word _Verstellung_ entirely in the sense of mental disguise or purposeful deception. In the closing paragraph he limits the possibilities. His remarks on this question are not without value for the students of certain literary problems. According to Dr. Eick, the really fundamental things which can never be imitated are all manifestations of positive life. For example, we cannot simulate courage, enthusiasm, humility. It is true that we can reproduce certain distinctive marks of courage and enthusiasm which may deceive the inexperienced; but the essence of these qualities can be expressed only by a person who has experienced them, and who possesses them. A brave man may simulate timidity and cowardice, the man who is capable of enthusiasm may wear the mask of apathetic indolence; all depressive and negative conditions may be imitated. But fulness of life and the sap which quickens it cannot be replaced by any dissimulation. The stupid person may persuade another stupid person to believe in his cleverness. But it is impossible to counterfeit cleverness before a clever person unless we possess a minimum of cleverness, because a certain amount of cleverness is needed for the deception itself. The real tone of truth’s voice can no more be copied than the fiery gleam of enthusiasm. At this point all the arts of deception fail; the voice contradicts the words. The man who possesses something of these qualities of soul can indeed simulate higher degrees of the same qualities, and can exploit them in unlimited measure. But the elemental things of life are inimitable, and lie beyond the reach of falsehood. He who imitates an elemental thing is immediately discovered—supposing, of course, that the discoverer has himself some share in the element. THE NECESSARY QUALIFICATIONS The idea that Datchery is a new character may safely be dismissed. It is in one of the characters already on the stage that we must find Datchery. I might proceed by taking the characters one by one, and by a process of exhaustion arrive at Datchery. But a simpler way may be to enumerate the qualifications required in Datchery, and to show that one character of the story possesses them all. The claims of the other characters may be then discussed.
