“We need the tonic of wildness...At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be indefinitely wild, unsurveyed and unfathomed by us because unfathomable. We can never have enough of nature.”

“We can never have enough of nature. We must be refreshed by the sight of inexhaustible vigor, vast and titanic features, the sea-cost with its wrecks, the wilderness with its living and its decaying trees, the thunder-cloud, and the rain which lasts three weeks and produces freshets. We need to witness our own limits transgressed, and some life pasturing freely where we never wander.”

“All good things are wild and free.”

“There are many fine things we cannot say if we have to shout.”

“A man who has at length found something to do will not need to get a new suit to do it in. If there is not a new man, how can the new clothes be made to fit? All men want, not something to do with, but something to do, or rather something to be. Perhaps we should never procure a new suit until we have so conducted that we feel like new men in the old.”

“When it is time to die, let us not discover that we never lived.”

“Most men appear never to have considered what a house is, and are actually though needlessly poor all their lives because they think that they must have such a one as their neighbors have. As if one were to wear any sort of coat which the tailor might cut out for him, or gradually leaving off palm-leaf hat or cap of woodchuck skin, complain of hard times because he could not afford to buy him a crown! It is possible to invent a house still more convenient and luxurious than we have, which yet all would admit that man could not afford to pay for. Shall we always study to obtain more of these things, and not sometimes be content with less?”
