Famous quotes containing the words animals, observed and/or pass:
“Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are layed waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.”
—Anton Pavlovich Chekhov (1860–1904)
“In a restaurant one is both observed and unobserved. Joy and sorrow can be displayed and observed “unwittingly,” the writer scowling naively and the diners wondering, What the hell is he doing?”
—David Mamet (b. 1947)
“Bring me an axe and spade,
Bring me a winding-sheet;
When I my grave have made
Let winds and tempests beat:
Then down I’ll lie as cold as clay.
True love doth pass away!”
—William Blake (1757–1827)
