Single Species

Famous quotes containing the words single and/or species:

    We saw many straggling white pines, commonly unsound trees, which had therefore been skipped by the choppers; these were the largest trees we saw; and we occasionally passed a small wood in which this was the prevailing tree; but I did not notice nearly so many of these trees as I can see in a single walk in Concord.
    Henry David Thoreau (1817–1862)

    Let us guard against saying that death is opposed to life. The living is merely a species of the dead, and a very rare species.
    Friedrich Nietzsche (1844–1900)
