The same Justice which punishes sin may also most graciously forgive it, and that no ban is so heavy but that by prayer and repentance it may be removed.
The Hound of the Baskervilles by Arthur Conan Doyle
While the individual man is an insoluble puzzle, in the aggregate he becomes a mathematical certainty. You can, for example, never foretell what any one man will do, but you can say with precision what an average number will be up to. Individuals vary, but percentages remain constant. So says the statistician.
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.
A man`s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose.A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things, so that he has a difficulty in laying his hands upon it. Now the skillful workman is very careful, indeed, as to what he takes into his brain-attic.He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it, there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.
To the logician all things should be seen exactly as they are, and to underestimate oneself is as much a departure from truth as to exaggerate one`s own powers.
The Memoirs of Sherlock Holmes by Sir Arthur Conan Doyle
A man should keep his little brain attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber room of his library, where he can get if he wants it.
