“There is a soul-jealousy that can be as frantic as any body-jealousy.”

“It is only when you touch the higher that you realize how low we may be among the possibilities of creation.”

“It is a pity he did not write in pencil. As you have no doubt frequently observed, the impression usually goes through — a fact which has dissolved many a happy marriage.”

“I think that I had better go, Holmes.””Not a bit, doctor. Stay where you are. I am lost without my Boswell.”

“It’s a very cheery thing to come into London by any of these lines which run high and allow you to look down upon the houses like this.”I thought he was joking, for the view was sordid enough, but he soon explained himself.”Look at those big, isolated clumps of buildings rising up above the slates, like brick islands in a lead-coloured sea.””The board-schools.””Light-houses, my boy! Beacons of the future! Capsules with hundreds of bright little seeds in each, out of which will spring the wiser, better England of the future.”

“It is only goodness which gives extras, and so I say again that we have much to hope from the flowers.”

“Dr. Watson’s summary list of Sherlock Holmes’s strengths and weaknesses:”1. Knowledge of Literature: Nil.2. Knowledge of Philosophy: Nil.3. Knowledge of Astronomy: Nil.4. Knowledge of Politics: Feeble.5. Knowledge of Botany: Variable. Well up in belladonna, opium, and poisons generally. Knows nothing of practical gardening.6. Knowledge of Geology: Practical but limited. Tells at a glance different soils from each other. After walks has shown me splashes upon his trousers, and told me by their colour and consistence in what part of London he had received them.7. Knowledge of Chemistry: Profound.8. Knowledge of Anatomy: Accurate but unsystematic.9. Knowledge of Sensational Literature: Immense. He appears to know every detail of every horror perpetrated in the century.10. Plays the violin well.11. Is an expert singlestick player, boxer, and swordsman.12. Has a good practical knowledge of British law.”

“What a lovely thing a rose is!”He walked past the couch to the open window and held up the drooping stalk of a moss-rose, looking down at the dainty blend of crimson and green. It was a new phase of his character to me, for I had never before seen him show any keen interest in natural objects. “There is nothing in which deduction is so necessary as religion,” said he, leaning with his back against the shutters. “It can be built up as an exact science by the reasoner. Our highest assurance of the goodness of Providence seems to me to rest in the flowers. All other things, our powers, our desires, our food, are all really necessary for our existence in the first instance. But this rose is an extra. Its smell and its color are an embellishment of life, not a condition of it. It is only goodness which gives extras, and so I say again that we have much to hope from the flowers.”

“A sandwich and a cup of coffee, and then off to violin-land, where all is sweetness and delicacy and harmony.”

“It is easy to be wise after the event.”

“The devil’s agents may be of flesh and blood, may they not?”

“The ways of fate are indeed hard to understand. If there is not some compensation hereafter, then the world is a cruel jest.”

“There is a danger there – a very real danger to humanity. Consider, Watson, that the material, the sensual, the worldly would all prolong their worthless lives. The spiritual would not avoid the call to something higher. It would be the survival of the least fit. What sort of cesspool may not our poor world become?”

“Is there any point to which you would wish to draw my attention?’ ‘To the curious incident of the dog in the night-time.’ ‘The dog did nothing in the night-time.”That was the curious incident,’ remarked Sherlock Holmes.”

“My dear Watson,” said [Sherlock Holmes], “I cannot agree with those who rank modesty among the virtues. To the logician all things should be seen exactly as they are, and to underestimate one’s self is as much a departure from truth as to exaggerate one’s own powers.”
