Mistakes and errors are the discipline through which we advance.

Every human being has a work to carry on within, duties to perform abroad, influence to exert, which are peculiarly his, and which no conscience but his own can teach.

All noble enthusiasms pass through a feverish stage, and grow wiser and more serene

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.

Fix your eyes on perfection and you make almost everything speed towards it.

The fewer the voices on the side of truth, the more distinct and strong must be your own.

What a sublime doctrine it is, that goodness cherished now is eternal life already entered on!
