“Between falsehood and useless truth there is little difference. As gold which he cannot spend will make no man rich, so knowledge which cannot apply will make no man wise.”

“There is no problem the mind of man can set that the mind of man cannot solve.”

“Sir, there is nothing too little for so little creature as man. It is by studying little things that we attain the great knowledge of having as little misery and as much happiness as possible.”

“Every man is rich or poor according to the proportion between his desires and his enjoyments.”

“He who has so little knowledge of human nature as to seek happiness by changing anything but his own dispositions will waste his life in fruitless efforts and multiply the griefs which he purposes to remove”

“He who makes a beast of himself gets rid of the pain of being a man.”

“He that reads and grows no wiser seldom suspects his own deficiency, but complains of hard words and obscure sentences, and asks why books are written which cannot be understood.”
