Sherlock Holmes’ multiple disguises reflect the multiple personality of Sir Arthur Conan Doyle (post 6)

My previous posts on Doyle made a good case for his multiple personality, but without discussing his most famous character, Sherlock Holmes, whose image is that of the fact-oriented ultra-rationalist, the last person you might suspect of having something as imaginative as multiple personality.

But in the vast literary commentary on, and adaptations of, Sherlock Holmes, there has been speculation about multiple personality, the most common being that super-villain Professor Moriarty didn’t exist, except as an imaginary person (an alternate personality) in Holmes’ mind.

Another source of speculation has been Holmes’ frequent use of disguises:

“Holmes would have made an actor, and a rare one. His expression, his manner, his very soul seemed to vary with every fresh part that he assumed…He had at least five small refuges in different parts of London in which he was able to change his personality…Here is the list of disguises used by Sherlock Holmes: a sailor, an asthmatic old master mariner, an amiable and simple-minded Nonconformist clergyman, a doddering opium smoker, a common loafer, a venerable Italian priest, an elderly book-collector, an East End familiar known to Captain Basil, a plumber with a rising business named Escott, an unshaven French ouvrier, a workman looking for a job, an old sporting man, an elderly woman, an Irish-American spy named Altamont.” https://www.arthur-conan-doyle.com/index.php/Sherlock_Holmes

In the following passage, note the reference to “exorcising” (demon possession is a pre-psychological theory of multiple personality); Holmes’ seeming to hear Moriarty’s voice (people with undiagnosed multiple personality often hear the voices of one or more of their alternate personalities) (even after the alternate personality's supposed death, because, as long as the person remains alive, death of an alternate personality often only means that the "dead" personality must remain inside; and the comparison of Holmes to Dorian Gray, a famous fictional character who has often been suspected of having multiple personality. (Search “Oscar Wilde” on this site.)

“As Watson says in The Final Problem, ‘… if [Holmes] could be assured that society was freed from Professor Moriarty he would cheerfully bring his own career to a conclusion.’ It was as if Holmes were exorcising himself. Yet even after Holmes ostensibly bested the ‘Napoleon of crime’ at the Reichenbach Falls, Moriarty exercised a hold over him. ‘I am not a fanciful person,’ said Holmes, ‘but I give you my word that I seemed to hear Moriarty’s voice screaming at me out of the abyss.’ It was, perhaps, the sound of his own demons that he was hearing. If Holmes is Dorian Gray, Moriarty equates to the picture he hides away in his attic—a grim reflection of the ravages of his soul that the detective keeps hidden from the world 
at large." https://strandmag.com/a-question-of-identity/
