Enthusiasm is the engine of success.

We must not tamper with the organic motion of the soul.

The other terror that scares us from self-trust is our consistency; a reverence for our past act or word, because the eyes of others have no other data for computing our orbit than our past acts, and we are loath to disappoint them.

There is no history; only biography.

We swim, day by day, on a river of delusions, and are effectually amused with houses and towns in the air, of which the men aboutus are dupes. But life is a sincerity.

Eyes are bold as lions,--roving, running, leaping, here and there, far and near. They speak all languages. They wait for no introduction; they are no Englishmen; ask no leave of age or rank; they respect neither property nor riches, neither learning nor power, nor virtue, nor sex, but intrude, and come again, and go through and through you in a moment of time. What inundation of life and thought is discharged from one soul into another through them!

The poisons are our principal medicines, which kill the disease and save the life.
