Famous quotes containing the word services:
“Working women today are trying to achieve in the work world what men have achieved all along—but men have always had the help of a woman at home who took care of all the other details of living! Today the working woman is also that woman at home, and without support services in the workplace and a respect for the work women do within and outside the home, the attempt to do both is taking its toll—on women, on men, and on our children.”
—Jeanne Elium (20th century)
“Civil servants and priests, soldiers and ballet-dancers, schoolmasters and police constables, Greek museums and Gothic steeples, civil list and services list—the common seed within which all these fabulous beings slumber in embryo is taxation.”
—Karl Marx (1818–1883)
“I see this evident, that we willingly accord to piety only the services that flatter our passions.”
—Michel de Montaigne (1533–1592)
