Famous quotes containing the word species:

    “Any reading not of a vicious species must be a good substitute for the amusements too apt to fill up the leisure of the labouring classes.”
    —James Madison (1751–1836)

    “Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.”
    —Ralph Waldo Emerson (1803–1882)

    “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)
