Others are affected by what I am, and say, and do. So that a single act of mine may spread and spread in widening circles, through a nation or humanity. Through my vice I intensify the taint of vice throughout the universe. Through my misery I make multitudes sad. On the other hand, every development of my virtue makes me an ampler blessing to my race. Every new truth that I gain makes me a brighter light to humanity.

We smile at the ignorance of the savage who cuts down the tree in order to reach its fruit; but the same blunder is made by every person who is over eager and impatient in the pursuit of pleasure.

I call that mind free which protects itself against the usurpations of society, and which does not cower to human opinion: Which refuses to be the slave or tool of the many or of the few, and guards its empire over itself as nobler than the empire of the world.

The mind, in proportion as it is cut off from free communication with nature, with revelation, with God, with itself, loses its life, just as the body droops when debarred from the air and the cheering light from heaven.

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

Of all the discoveries which men need to make, the most important, at the present moment, is that of the self-forming power treasured up in themselves. They little suspect its extent, as little as the savage apprehends the energy which the mind is created to exert on the material world.

Science and art may invent splendid modes of illuminating the apartments of the opulent; but these are all poor and worthless compared with the common light which the sun sends into all our windows, which he pours freely, impartially over hill and valley, which kindles daily the eastern and western sky; and so the common lights of reason, and conscience, and love, are of more worth and dignity than the rare endowments which give celebrity to a few.
