Knowledge is essential to freedom.

No one should part with their individuality and become that of another.

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

I call that mind free which jealously guards its intellectual rights and powers, which calls no man master, which does not content itself with a passive or hereditary faith, which opens itself to light whencesoever it may come, which receives new truth as an angel from Heaven.

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.

May your life preach more loudly than your lips.

A general loftiness of sentiment, independence of men, consciousness of good intentions, self-oblivion in great objects, clear views of futurity; thoughts of the blessed companionship of saints and angels, trust in God as the friend of truth and virtue,--these are the states of mind in which I should live.
