Famous quotes containing the word species:
““If Steam has done nothing else, it has at least added a whole new Species to English Literature ... the booklets—the little thrilling romances, where the Murder comes at page fifteen, and the Wedding at page forty—surely they are due to Steam?”
“And when we travel by electricity—if I may venture to develop your theory—we shall have leaflets instead of booklets, and the Murder and the Wedding will come on the same page.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“Prohibition will work great injury to the cause of temperance. It is a species of intemperance within itself, for it goes beyond the bounds of reason in that it attempts to control a man’s appetite by legislation, and makes a crime out of things that are not crimes. A Prohibition law strikes a blow at the very principles upon which our government was founded.”
—Abraham Lincoln (1809–1865)
“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)
