Famous quotes containing the word species:
“Heaven and hell suppose two distinct species of men, the good and the bad. But the greatest part of mankind float betwixt vice and virtue.”
—David Hume (1711–1776)
““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)
“If we consider the superiority of the human species, the size of its brain, its powers of thinking, language and organization, we can say this: were there the slightest possibility that another rival or superior species might appear, on earth or elsewhere, man would use every means at his disposal to destroy it.”
—Jean Baudrillard (b. 1929)
