I, who cannot stay in my chamber for a single day without acquiring some rust, and when sometimes I have stolen forth for a walk at the eleventh hour of four o'clock in the afternoon, too late to redeem the day, when the shades of night were already beginning to be mingled with the daylight, have felt as if I had committed some sin to be atoned for.
Henry David ThoreauOur poets have sung of wine, the product of a foreign plant which commonly they never saw, as if our own plants had no juice in them more than the singers.
Henry David ThoreauThe earth is not a mere fragment of dead history, stratum upon stratum like the leaves of a book, to be studied by geologists and antiquaries chiefly, but living poetry like the leaves of a tree, which precede flowers and fruit ~ not a fossil earth, but a living earth; compared with whose great central life all animal and vegetable life is merely parasitic. Its throes will heave our exuviæ from their graves ... You may melt your metals and cast them into the most beautiful moulds you can; they will never excite me like the forms which this molten earth flows out into.
Henry David ThoreauWhat is commonly honored with the name of Friendship is no very profound or powerful instinct. Men do not, after all, love their Friends greatly. I do not often see the farmers made seers and wise to the verge of insanity by their Friendship for one another. They are not often transfigured and translated by love in each other's presence. I do not observe them purified, refined, and elevated by the love of a man.
