The civilized nations--Greece, Rome, England--have been sustained by the primitive forests which anciently rotted where they stand. They survive as long as the soil is not exhausted. Alas for human culture! little is to be expected of a nation, when the vegetable mould is exhausted, and it is compelled to make manure of the bones of its fathers. There the poet sustains himself merely by his own superfluous fat, and the philosopher comes down on his marrow-bones.
Henry David ThoreauLet us consider under what disadvantages Science has hitherto labored before we pronounce thus confidently on her progress.
Henry David ThoreauOur whole life is startlingly moral. There is never an instant's truce between virtue and vice.
Henry David ThoreauWhat other words, we may almost ask, are memorable and worthy to be repeated than those which love has inspired? It is wonderful that they were ever uttered. They are few and rare indeed, but, like a strain of music, they are incessantly repeated and modulated by the memory. All other words crumble off with the stucco which overlies the heart. We should not dare to repeat these now aloud. We are not competent to hear them at all times.
