Famous quotes containing the words rainbow and/or books:
“and Venus among the fishes skips and is a she-dolphin
she is the gay, delighted porpoise sporting with love and the sea
she is the female tunny-fish, round and happy among the males
and dense with happy blood, dark rainbow bliss in the sea.”
—D.H. (David Herbert)
“Postmodernism is, almost by definition, a transitional cusp of social, cultural, economic and ideological history when modernisms high-minded principles and preoccupations have ceased to function, but before they have been replaced with a totally new system of values. It represents a moment of suspension before the batteries are recharged for the new millennium, an acknowledgment that preceding the future is a strange and hybrid interregnum that might be called the last gasp of the past.”
—Gilbert Adair, British author, critic. Sunday Times: Books (London, April 21, 1991)
