4. ”Are you conscious of the restful influence which the stars exert? To me they are the most soothing things in Nature. I am proud to say that I don't know the name of one of them.

But when a man is hot and flurried, and full of his own little ruffled dignities and infinitesimal misfortunes, then a star bath is the finest thing in the world.”

8. "Detection is, or ought to be, an exact science, and should be treated in the same cold and unemotional manner. You have attempted to tinge it with romanticism, which produces much the same effect as if you worked a love-story or an elopement into the fifth proposition of Euclid."

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 skilful 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."

19. “It is not really difficult to construct a series of inferences, each dependent upon its predecessor and each simple in itself. If, after doing so, one simply knocks out all the central inferences and presents one's audience with the starting-point and the conclusion, one may produce a startling, though perhaps a meretricious, effect.”
20. "Life is infinitely stranger than anything which the mind of man could invent."
21. "Love has been taken away from the poets, and has been brought within the domain of true science. It may prove to be one of the great cosmic elementary forces. When the atom of hydrogen draws the atom of chlorine towards it to form the perfected molecule of hydrochloric acid, the force which it exerts may be intrinsically similar to that which draws me to you. Attraction and repulsion appear to be the primary forces. This is attraction."
22. “Mediocrity does not see higher than itself. But talent instantly recognizes the genius.”
23. ”My mind rebels at stagnation. Give me problems, give me work, give me the most abstruse cryptogram, or the most intricate analysis, and I am in my own proper atmosphere. I can dispense then with artificial stimulants. But I abhor the dull routine of existence. I crave for mental exaltation.”

Treasure it in your minds and pass it on to your children, for the memory of a great age is the most precious treasure that a nation can possess. As the tree is nurtured by its own cast leaves so it is these dead men and vanished days which may bring out another blossoming of heroes, of rulers, and of sages.”
28. “Several incidents in my life have convinced me of spiritual interposition--of the promptings of some beneficent force outside ourselves, which tries tohelp us where it can.”
29. “So complex is the human spirit that it can itself scarce discern the deep springs which impel it to action.”
30. "Still, jealousy is a strange transformer of characters."
31. "Streams may spring from one source, and yet some be clear and some be foul."
32. "The charlatan is always the pioneer. From the astrologer came the astronomer, from the alchemist the chemist, from the mesmerist the experimental psychologist. The quack of yesterday is the professor of tomorrow."
33. "Then must you strive to be worthy of her love. Be brave and pure, fearless to the strong and humble to the weak; and so, whether this love prosper or no, you will have fitted yourself to be honored by a maiden's love, which is, in sooth, the highest guerdon which a true knight can hope for."
34. “The old couple had come round to that tragic imitation of the dawn of life when husband and wife, having lost or scattered all those who were their intimates, find themselves face to face and alone once more, their work done, and the end nearing fast.

39. “The unexpected has happened so continually in my life that it has ceased to deserve the name.”
40. "The world is full of obvious things which nobody by any chance ever observes."
41. "To put the world right in order, we must first put the nation in order; to put the nation in order, we must first put the family in order; to put the family in order, we must first cultivate our personal life; we must first set our hearts right."
42. “Unwelcome truths are not popular.”
43. “We surely know by some nameless instinct more about our futures than we think we know.”
44. “What can we know? What are we all? Poor silly half-brained things peering out at the infinite, with the aspirations of angels and the instincts of beasts.”
45. “When such men, who are beyond hope and fear, begin in their dim minds to see the source their woes, it may be an evil time for those who have wronged them. The weak man becomes strong when he has nothing, for then only can he feel the wild, mad thrill of despair.”
