Famous quotes containing the words imaginary and/or numbers:
“Fiction is not imagination. It is what anticipates imagination by giving it the form of reality. This is quite opposite to our own natural tendency which is to anticipate reality by imagining it, or to flee from it by idealizing it. That is why we shall never inhabit true fiction; we are condemned to the imaginary and nostalgia for the future.”
—Jean Baudrillard (b. 1929)
“The principle of majority rule is the mildest form in which the force of numbers can be exercised. It is a pacific substitute for civil war in which the opposing armies are counted and the victory is awarded to the larger before any blood is shed. Except in the sacred tests of democracy and in the incantations of the orators, we hardly take the trouble to pretend that the rule of the majority is not at bottom a rule of force.”
—Walter Lippmann (1889–1974)
