[T]omorrow is a new day. You shall begin it well & serenely, & with too high a spirit to be cumbered with your old nonsense. This day ... is too dear with its hopes & invitations to waste a moment on the rotten yesterdays.
Natural science sharpens the discrimination. There is no false logic in nature. All its properties are permanent: the acids and metals never lie; their yea is yea, their nay, nay. They are newly discovered but not new.
I am the lover of uncontained and immortal beauty. In the wilderness, I find something more dear and connate than in streets or villages. In the tranquil landscape, and especially in the distant line of the horizon, man beholds somewhat as beautiful as his own nature.
He in whom the love of truth predominates . . . submits to the inconvenience of suspense and imperfect opinion; but he is a candidate for truth . . . and respects the highest law of his being.
The pest of society are the egotist, they are dull and bright, sacred and profane, course and fine. It is a disease that like the flu falls on all constitutions.

But I cannot recite, even thus rudely, laws of the intellect, without remembering that lofty and sequestered class of men who have been its prophets and oracles, the high-priesthood of the pure reason, the Trismegisti, the expounders of the principles of thought from age to age.
Faith and love are apt to be spasmodic in the best minds: Men live on the brink of mysteries and harmonies into which yet they never enter, and with their hand on the doorlatch they die outside.
Explore, and explore, and explore. Be neither chided nor flattered out of your position of perpetual inquiry. Neither dogmatise yourself, nor accept another's dogmatism. Why should you renounce your right to traverse the star-lit deserts of truth, for the premature comforts of an acre, house, and barn? Truth also has its roof, and bed, and board. Make yourself necessary to the world, and mankind will give you bread, and if not store of it, yet such as shall not take away your property in all men's possessions, in all men's affections, in art, in nature, and in hope.
