“Nothing which has entered into our experience is ever lost”

“No power in society, no hardship in your condition can depress you, keep you down, in knowledge, power, virtue, influence, but by your own consent.”

“Every mind was made for growth, for knowledge, and its nature is sinned against when it is doomed to ignorance”

“He who is false to the present duty breaks a thread in the loom, and you will see the effect when the weaving of a lifetime is unraveled”

“It is not the quantity but the quality of knowledge which determines the mind's dignity”

“Error is discipline through which we advance”
