"I want you to read the true system of the heart, drafted by a decent man and published under another name. I do not want you to be biased against good and useful books merely because a man unworthy of reading them has the audacity to call himself the Author."

“Watch a cat when she comes into a room for the first time; she goes from place to place, she sniffs about and examines everything, she is never still for a moment; she is suspicious of everything till she has examined it and found out what it is. It is the same with the child when he begins to walk, and enters, so to speak, the room of the world around him. The only difference is that, while both use sight, the child uses his hands and the cat that subtle sense of smell which nature has bestowed upon it. It is this instinct, rightly or wrongly educated, which makes children skilful or clumsy, quick or slow, wise or foolish.”

“As soon as we have contrived to give our pupil an idea of the word "Useful," we have got an additional means of controlling him, for this word makes a great impression on him, provided that its meaning for him is a meaning relative to his own age, and provided he clearly sees its relation to his own well-being. This word makes no impression on your scholars because you have taken no pains to give it a meaning they can understand, and because other people always undertake to supply their needs so that they never require to think for themselves, and do not know what utility is.

“The supreme enjoyment is in satisfaction with oneself ; it is in order to deserve this satisfaction that we are placed on earth and endowed with freedom.”

“Days of absence, sad and dreary,Clothed in sorrow's dark array,—Days of absence, I am weary: She I love is far away.”
