Famous quotes containing the words cloud and/or base:

    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)

    Were I as base as is the lowly plain,
    And you, my Love, as high as heaven above,
    Yet should the thoughts of me, your humble swain,
    Ascend to heaven in honour of my love.
    Joshua Sylvester (1561–1618)
