Famous quotes containing the words soil and/or chemistry:

    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 Thoreau (1817–1862)

    If thought makes free, so does the moral sentiment. The mixtures of spiritual chemistry refuse to be analyzed.
    Ralph Waldo Emerson (1803–1882)
