From the simple fact that even a man of plain common-sense and strong will may be driven to sleeplessness, or well nigh to madness, by the haunting presence of some wretched trifle, some mere jingle or rhyme, or idle memory, we may infer that we have here a great power which must in some way be capable of being led to great or useful results by some very easy process.  I once wrote a sketch, never completed, in which I depicted a man of culture who, having lost an old manuscript book which he had regarded in a light, semi-incredulous manner as a fetish, or amulet, on which his luck depended, began to be seriously concerned, and awaking to the fact, deliberately cultivated his alarm as a psychological study, till he found himself, even with his eyes wide open as an observer in terrible fear, or a semi-monomaniac.  The recovery of his lost charm at once relieved him.  This was a diversion of Attention for a deliberate purpose, which might have been varied ad infinitum to procure very useful results.  But I have myself known a man in the United States, who, having lost—­he being an actor or performer—­a certain article of theatrical properties on which he believed “luck” depended, lost all heart and hope, and fell into a decline, from which he never recovered.  In this, as in all such cases, it was not so much conviction or reason which influenced the sufferer as the mere effect of Attention often awakened till it had become what is known as a fixed idea.

A deliberate reflection on what I have here advanced can hardly fail to make it clear to any reader that if he really desires to take an interest in any subject, it is possible to do so, because Nature has placed in every mind vast capacity for attention or fixing ideas, and where the Attention is fixed, Interest, by equally easy process, may always be induced to follow.  And note that these preliminary preparations should invariably be as elementary and easy as possible, this being a condition which it is impossible to exaggerate.  In a vast majority of cases people who would fain be known as taking an interest in Art begin at the wrong end, or in the most difficult manner possible, by running through galleries where they only acquire a superficial knowledge of results, and learn at best how to talk showily about what they have skimmed.  Now to this end a good article in a cyclopaedia, or a small treatise like that of TAINE’S “AEsthetic” thoroughly read and re-read, till it be really mastered, and then verified by study of a very few good pictures in a single collection, will do more to awaken sincere interest than the loose ranging through all the exhibitions in the world.  I have read in many novels thrilling descriptions of the effect and results when all the glories of the Louvre or Vatican first burst upon some impassioned and unsophisticated youth, who from that moment found himself an Artist—­ but I still maintain that it would have been a hundred times better for him had his Attention and Interest been previously attracted to a few pictures, and his mind accustomed to reflect on them.
