Sherlock Holmes

"It is a capital mistake to theorize before one has data."

"The world is full of obvious things which nobody by any chance ever observes."

"My dear Watson, you see everything. You observe nothing."

"I have no data yet. It is a capital mistake to theorize before you have data."

"When you have eliminated the impossible, whatever remains however improbable must be the truth."

"I am a creature of habit and I have my satisfactions."

"The truth is rarely pure and never simple."

"Crime is common. Logic is rare."

"You know my methods, Watson."

"How often have I said to you that when you have eliminated the impossible?"

"I never make exceptions. An exception disproves the rule."

"A man should keep his little brain attic stocked with all the furniture that he is likely to use."

"The curious incident of the dog in the night-time."

"I cannot agree with those who rank modesty amongst the virtues."

"Detection is, or ought to be, an exact science and should be treated in the same cold and unemotional manner."

"I deduce, therefore I exist."

"Watson, you have some remarkable qualities when you choose to exert them."

"My mind rebels at stagnation. Give me problems, give me work!"

"The game is afoot!"

"You will find that very useful if you will only think so."

"There is nothing in this world more important than truth."

"Elementary, my dear Watson."

"I never guess. It is a shocking habit destructive to the logical faculty."

"I cannot afford to waste energy upon trifles."

"Your powers of observation are remarkable, but you employ them for trivial things."

"Women are naturally secretive, and they like to do their own secreting."

"It is of the highest importance in the art of detection to be able to recognize out of a number of facts."

"I cannot help thinking that it is the greatest gift that a man can be born into a world of interests."

"Ah, that would be telling. Now is not the time."

"The public is none the wiser, and the criminal alone suffers."
