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

“It seems as if no man had ever died in America before, for in order to die you must first have lived. These men, in teaching us how to die, have at the same time taught us how to live.”

“The universe constantly and obediently answers to our conceptions; whether we travel fast or slow, the track is laid for us. Let us spend our lives in conceiving then. The poet or the artist never yet had so fair and noble a design but some of his posterity at least could accomplish it.”

“We are sometimes made aware of a kindness long passed, and realize that there have been times when our friends' thoughts of us were of so pure and lofty a character that they passed over us like the winds of heaven unnoticed; when they treated us not as what we were, but as what we aspired to be.”

“We live a short period of time in this world, but we live it according to the laws of eternal life.”

“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 should be blessed if we lived in the present always, and took advantage of every accident that befell us, like the grass which confesses the influence of the slightest dew that falls on it; and did not spend our time in atoning for the neglect of past opportunities, which we call doing our duty.”
