Famous quotes containing the word blade:
“When he painted a road, the roadmakers were there in his imagination. When he painted the turned earth of a ploughed field, the gesture of the blade turning the earth was included in his own act. Wherever he looked he saw the labour of existence; and this labour, recognized as such, was what constituted reality for him.”
—John Berger (b. 1926)
