People ask me, will I write any more Sherlock Holmes stories and I certainly don’t think it’s at all probable. But as I grow older, the psychic subject always grows in intensity and one becomes more earnest upon it, and I should think that my few remaining years will be probably devoted much more in that direction than in the direction of literature. My principal thoughts are that i should extend, if I can, that knowledge, which I have on psychic matters, and spread it as far as I can to those who have been less fortunate.
I don’t for one moment suppose that I’m taking it upon my self to say that I’m the inventor of spiritualism, or that I’m even the principal exponent of it. There are many great mediums, many great psychical researchers, investigators of all sorts — all that I can do is be a gramophone on the subject, to go about, to meet people face to face, to try to make them understand that this thing is not the foolish thing, which is so often represented, but that it really is a great philosophy and, as I think, the basis for all religious improvement in the future of the human race.” ~ Arthur Conan Doyle
