Do you remember what Darwin says about music? He claims that the power of producing and appreciating it existed among the human race long before the power of speech was arrived at. Perhaps that is why we are so subtly influenced by it. There are vague memories in our souls of those misty centuries when the world was in its childhood.' That's a rather broad idea,' I remarked. One's ideas must be as broad as Nature if they are to interpret Nature,' he answered.
I was fifteen when I first met Sherlock Holmes, fifteen years old with my nose in a book as I walked the Sussex Downs, and nearly stepped on him. In my defense I must say it was an engrossing book, and it was very rare to come across another person in that particular part of the world in that war year of 1915.
To his eyes all seemed beautiful, but to me a tinge of melancholy lay upon the countryside, which bore so clearly the mark of the waning year, Yellow leaves carpeted the lanes and fluttered down upon us as we passed, The rattle of our wheels died away as we drove through drifts of rotting vegetation--sad gifts, as it seemed to me, for Nature to throw before the carriage of the returning heir of the Baskervilles.
Over the green squares of the fields and the low curves of a wood there rose in the distance a grey, melancholy hill, with a strange jagged summit, dim and vague in the distance like some fantastic landscape in a dream. Baskerville sat for a long time, his gaze fixed upon it, and I read upon his eager face how much it meant to him, this first sight of that strange spot where the men of his blood had held sway so long and left their mark so deep.
On glancing over my notes of the seventy odd cases in which I have during the last eight years studied the methods of my friend Sherlock Holmes, I find many tragic, some comic, a large number merely strange, but none commonplace; for, working as he did rather for the love of his art than for the acquirement of wealth, he refused to associate himself with any investigation which did not tend towards the unusual, and even the fantastic.
On westminster Bridge, Arthur was struck by the brightness of the streetlamps running across like a formation of stars. They shone white against the black coats of the marching gentlefold and fuller than the moon against the fractal spires of Westminster. They were, Arthur quickly realized, the new electric lights, which the city government was installing, avenue by avenue, square by square, in place of the dirty gas lamps that had lit London's public spaces for a century. These new electric ones were brighter. They were cheaper. They required less maintenance. And they shone farther into the dime evening, exposing every crack in the pavement, every plump turtle sheel of stone underfoot. So long to the faint chiaroscuro of London, to the ladies and gentlemen in black-on-black relief. So long to the era of mist and carbonized Newcastle coal, to the stench of the Blackfriars foundry. Welcome to the cleasing glare of the twentieth century.
What is the meaning of it Watson?What object is served by this circle of misery and violence and fear?It must tend to some end or else our universe is ruled by chance,which is unthinkable.But what end?There is this long standing perennial problem to which human reason is as far from an answer as ever.
Our relationship with literary characters, at least to those that exercise a certain attraction over us, rests in fact on a denial. We know perfectly well, on a conscious level, that these characters do not exist, or in any case do not exist in the same way as do the inhabitants of the real world. But things manifest in an entirely different way on the unconscious level, which is interested not in the ontological differences between worlds but in the effect they produce on the psyche.Every psychoanalyst knows how deeply a subject can be influenced, and even shaped, sometimes to the point of tragedy, by a fictional character and the sense of identification it gives rise to. This remark must first of all be understood as a reminder that we ourselves are usually fictional characters for other people 
There are many men in London, you know, who, some from shyness, some from misanthropy, have no wish for the company of their fellows. Yet they are not averse to comfortable chairs and the latest periodicals. It is for the convenience of these that the Diogenes Club was started, and it now contains the most unsociable and unclubbable men in town. No member is permitted to take the least notice of any other one. Save in the Stranger's Room, no talking is, under any circumstances, allowed, and three offenses, if brought to the notice of the committee, render the talker liable to expulsion. My brother was one of the founders, and I have myself found it a very soothing atmosphere.
