Famous quotes containing the word human:
“It is better to pay court to a queen ... than to worship, as we too often do, some unworthy person whose wealth is his sole passport into society. I believe that a habit of respect is good for the human race.”
—M. E. W. Sherwood (1826–1903)
“There is no human failure greater than to launch a profoundly important endeavour and then leave it half done. This is what the West has done with its colonial system. It shook all the societies in the world loose from their old moorings. But it seems indifferent whether or not they reach safe harbour in the end.”
—Barbara Ward (1914–1981)
